HOME AUTOMATION AND SECURITY FOR MOBILE DEVICES
ABSTRACT
As mobile devices continue to grow in popularity and functionality, the demand for advanced ubiquitous mobile applications in our daily lives also increases. This paper deals with the design and implementation of HASec, a Home Automation and Security system for mobile devices, that leverages mobile technology to provide essential security to our homes and associated control operations.
In particular, with the help of mobile devices, HASec operates and controls motion detectors and video cameras for remote sensing and surveillance, streams live video and records it for future playback, and finally manages operations on home appliances, such as turning ON/OFF a television or microwave or altering the intensity of lighting around the house.
The proposed home security solution hinges on our novel integration of cameras and motion detectors into a mobile application. For instance, when motion is detected, the cameras automatically initiate recording and the iOS device alerts the homeowner of the possible intrusion.
HASec has two main components interacting with each other: the iOS application that executes on the mobile device and server-side scripts that run in a cloud. Although HA-Sec is implemented for Apple's iOS devices such as iPhone, iPod Touch, and iPad, it can be easily ported to other mobile platforms. Furthermore, our application is not only limited to smart-phones but also can be used by feature phones through their browsers.

DESIGN AND DEVELOPMENT OF MICROCONTROLLER BASED ELECTRONIC QUEUE CONTROL SYSTEMS
ABSTRACT
In this work, low-cost, portable microcontroller based electronic queue control (EQC) systems have been developed for the purpose of controlling queue in banking, hotel reservation counter, ticket counter, insurance company, customer service center etc. The aim of the designed systems is to maintain a queue with order and efficiency.
Two different queue control systems have been implemented with slightly different features. In EQC system-1, a general display has been used for displaying token number and service counter number whereas in EQC system-2, each token number has been displayed individually in each service counter with separate displays.
In the both systems, each customer has to collect a token and then will be served whenever the token number is displayed. The systems were designed around a 16F72 IC, a low-cost 8-bit PIC microcontroller and entirely software controlled.
The control programs have been developed using the PIC assembly language. Finally, the systems have been tested under different conditions to evaluate their performance.

DESIGN AND IMPLEMENTATION OF PYROELECTRIC INFRARED SENSOR BASED SECURITY SYSTEM USING MICROCONTROLLER
ABSTRACT
This paper evaluates the development of a Low-cost security system using small PIR (Pyroelectric Infrared) sensor built around a microcontroller. The low-power PIR detectors take advantage of pyroelectricity to detect a human body that is a constant source of Passive Infrared (radiation in the infrared region).
The system senses the signal generated by PIR sensor detecting the presence of individuals not at thermal equilibrium with the surrounding environment. Detecting the presence of any unauthorized person in any specific time interval, it triggers an alarm & sets up a call to a predefined number through a GSM modem.
This highly reactive approach has low computational requirement, therefore it is well-suited to surveillance, industrial applications and smart environments. Tests performed gave promising results.

ACCELEROMETER ASSISTED HIGH BANDWIDTH CONTROL OF TIP-TILT MIRROR FOR PRECISION POINTING STABILITY
ABSTRACT
Pointing stability that defines acceptable displacement of an observation target on the optical detector during the exposure time in a satellite telescope system largely dominates the quality of the image. This research proposes a new control approach to improve pointing stability using a tip-tilt mirror.
While conventional control systems for a tip-tilt mirror use feedback error signals obtained from the optical detector, the signal loses enough bandwidth to compensate for high frequency disturbances when pointing at a dark reference guide star.
This paper presents a control system subsidiarily using accelerometers to generate high bandwidth feedforward control references to a tip-tilt mirror by properly identifying transfer function between acceleration and pointing displacement. The numerical simulation and experiments using a disturbance source and a tip-tilt mirror verifies feasibility of this method.

A MICROCONTROLLER BASED MULTI-FUNCTION SOLAR TRACKING SYSTEM
ABSTRACT
Renewable energy solutions are becoming increasingly popular. Photovoltaic (solar) systems are but one example. Maximizing power output from a solar system is desirable to increase efficiency.
In order to maximize power output from solar panels, one needs to keep the panels aligned with the sun. As such, a means of tracking the sun is required. This is definitely a more cost effective solution than purchasing additional solar panels. It has been estimated that the yield from solar panels can be increased by 30 to 60 percent by utilizing a tracking system instead of a stationary array.
In this paper, a prototype for a microcontroller-based multi-function solar tracking system is described, which will keep the solar panels aligned with the sun in order to maximize efficiency.
The maximum power point tracking (MPPT) data can be transmitted in real time to other solar systems in need of this data.

POWER HARVESTING FOR SMART SENSOR NETWORKS IN MONITORING WATER DISTRIBUTION SYSTEM
ABSTRACT
Recently, there has been a growing interest in using wireless sensor networks for monitoring water distribution infrastructure to help drinking water utilities to have better understanding of hydraulic and water quality statement of their underground assets.
One of the challenges is limited power resources for operating the smart sensors and sensor networks. Current common used power supplies for sensor node are batteries. Batteries have many drawbacks such as short life time and need to be replaced on regular basis which is uneconomical and unmanageable in hard access environment such as buried underground water pipelines.
Energy harvesting of ambient energy in the water pipeline and powering wireless sensor node including sensing, processing, and communications would be particularly attractive option because the life time of the node will be potentially infinite for supporting wireless sensor networks.
The paper will review and discuss the potential of using power harvesting techniques for monitoring water distribution networks and the work done in the area of monitoring water distribution systems using smart sensor networks.

A NOVEL LIGHT-SENSOR-BASED INFORMATION TRANSMISSION SYSTEM FOR INDOOR POSITIONING AND NAVIGATION
ABSTRACT
This paper describes a novel light-sensor-based information transmission system for indoor positioning and navigation with particular benefits for mobile and wearable computers. It can seamlessly extend outdoor GPS tracking to the indoor environment.
In a novel manner, fluorescent light is used as the medium to transmit information, which is encoded by using a pulse-frequency modulation technique. The user receives the encoded light information through a photoreceiver. The information is passed into the wearable or mobile computer after the data are decoded.
This information allows positioning information to be given to indoor mobile and wearable computers. We design an economical transmitter circuit by adding a few components to a commercial electronic ballast circuit for fluorescent lamps with a price of less than 10 USD.
The proposed system can be used in indoor guidance and navigation applications. Exemplary applications are included in the paper, with experimented results detailed.

AUTONOMOUS PEDESTRIAN COLLISION AVOIDANCE USING A FUZZY STEERING CONTROLLER
ABSTRACT
Collision avoidance is one of the most difficult and challenging automatic driving operations in the domain of intelligent vehicles. In emergency situations, human drivers are more likely to brake than to steer, although the optimal maneuver would, more frequently, be steering alone.
This statement suggests the use of automatic steering as a promising solution to avoid accidents in the future. The objective of this paper is to provide a collision avoidance system (CAS) for autonomous vehicles, focusing on pedestrian collision avoidance. The detection component involves a stereo-vision-based pedestrian detection system that provides suitable measurements of the time to collision.
The collision avoidance maneuver is performed using fuzzy controllers for the actuators that mimic human behavior and reactions, along with a high-precision Global Positioning System (GPS), which provides the information needed for the autonomous navigation.
The proposed system is evaluated in two steps. First, drivers' behavior and sensor accuracy are studied in experiments carried out by manual driving. This study will be used to define the parameters of the second step, in which automatic pedestrian collision avoidance is carried out at speeds of up to 30 km/h. The performed field tests provided encouraging results and proved the viability of the proposed approach.

THE INTELLIGENT EMBEDDED CONTROL WARNING SYSTEM FOR CAR REVERSING
ABSTRACT
Most of the car drivers used the reverse radar or a reverse camera to detect the road situation behind the vehicle when it is engaged in reverse gear. As a matter of fact, the pedestrians can virtually know if the vehicle is backing up or not only by seeing the permanent bright reverse lamps. And as there is not much change with the reverse lamp to be seen, therefore their warning function for pedestrians seems to be still insufficient eventually.
Therefore, this research tries to design a set of embedded intelligent car backup warning system so as to promote the safety of the walkers or the other drivers on the road. This embedded system uses Microsoft Win CE operating system and matches with the Mini2440 developing board. It also uses the Visual Studio 2005 for developing the intelligent touch panel operating mode.
The UART interface on the Mini 2440 developing board controls the frequency converter, RC server and LED by using PIC16F877 to transform the signal of the sensors. And then, connecting to the sensors of angle, luminosity and distance so as to read the voltage value of the sensor and transferring them into actual values and followed by using 27 fuzzy logic rules to carry on the fuzzy logic deduction. And the angle of the LED reverse lamp bracket is adjusted and driven automatically according to the results of this logic deduction eventually.
This research tries to do the simulated test by using a mobile frame in the same height as a real automobile. To let the test mobile frame being located 240 cm away from the obstacle and then start the driven motor and set the frequency of it to be with 60 Hz. (in other words, its speed is approximately in 2.52 Km/h.) the let the test mobile frame to stop at 40 cm in front of the obstacle.
We found out that the warning lamp bracket installation angle will be changed correspondently with the distance between test mobile frame and obstacle and being declined automatically from 90 degree to 0 degree. Apparently, from th- - e test results, it has been proven that this system can reach the goal of automatically controlled car back-up warning function truly.

ADVANCEMENTS IN NONCONTACT, MULTIPARAMETER PHYSIOLOGICAL MEASUREMENTS USING A WEBCAM
ABSTRACT
We present a simple, low-cost method for measuring multiple physiological parameters using a basic webcam. By applying independent component analysis on the color channels in video recordings, we extracted the blood volume pulse from the facial regions.
Heart rate (HR), respiratory rate, and HR variability (HRV, an index for cardiac autonomic activity) were subsequently quantified and compared to corresponding measurements using Food and Drug Administration-approved sensors.
High degrees of agreement were achieved between the measurements across all physiological parameters. This technology has significant potential for advancing personal health care and telemedicine.

CLOSED-LOOP ANESTHETIC DRUG CONCENTRATION ESTIMATION USING CLINICAL-EFFECT FEEDBACK
ABSTRACT
This letter presents a novel closed-loop approach to anesthetic drug concentration estimation using clinical-effect measurement feedback. Compared with the open-loop prediction used in current target-controlled infusion systems, closed-loop estimation exploits the discrepancy between the measured and predicted clinical effects to make corrections to the drug-concentration estimate, achieving improved robustness against variability in the patient pharmacokinetics and pharmacodynamics.
A robust estimator, which processes drug administration and clinical-effect measurements to estimate the plasma- and effect-site drug concentrations, is designed using -synthesis theory. Initial proof of principle of the closed-loop estimation is demonstrated using the Monte Carlo simulation of surgical procedures with a wide range of patient models.
Closed-loop estimation results in statistically significant reductions in median percentage, median absolute percentage, and maximum absolute percentage drug-concentration errors compared to open-loop prediction.

MULTIPLE FUNCTIONAL ECG SIGNAL IS PROCESSING FOR WEARABLE APPLICATIONS OF LONG-TERM CARDIAC MONITORING
ABSTRACT
In this paper, an integrated electrocardiogram (ECG) signal-processing scheme is proposed. Using a systematic wavelet transform algorithm, this signal-processing scheme can realize multiple functions in real time, including baseline-drift removal, noise suppression, QRS detection, heart beat rate prediction and classification, and clean ECG reconstruction.
Utilizing the novel low-cost hardware architecture, the proposed ECG signal-processing scheme is implemented in application-specific integrated circuits with 0.18 µm CMOS technology.
This ECG signal-processor chip achieves low area and power consumptions, and is highly suitable for wearable applications of long-term cardiac monitoring.

HEARTBEAT CLASSIFICATION USING FEATURE SELECTION DRIVEN BY DATABASE GENERALIZATION CRITERIA
ABSTRACT
In this paper, we studied and validated a simple heart beat classifier based on ECG feature models selected with the focus on an improved generalization capability. We considered features from the RR series, as well as features computed from the ECG samples and different scales of the wavelet transform, at both avail able leads.
The classification performance and generalization were studied using publicly available databases: the MIT-BIH Arrhythmia, the MIT-BIH Supraventricular Arrhythmia, and the St. Pe tersburg Institute of Cardiological Technics (INCART) databases. The Association for the Advancement of Medical Instrumentation recommendations for class labeling and results presentation were followed.
A floating feature selection algorithm was used to obtain the best performing and generalizing models in the training and validation sets for different search configurations. The best model found comprehends eight features, was trained in a partition of the MIT-BIH Arrhythmia, and was evaluated in a completely disjoint partition of the same database.
The results obtained were: global accuracy of 93%; for normal beats, sensitivity (S) 95%, positive predictive value (P+) 98%; for supraventricular beats, S 11%, P+ 39%; and for ventricular beats S 81%, P+ 87%. In order to test the generalization capability, performance was also evaluated in the INCART, with results comparable to those obtained in the test set.
This classifier model has fewer features and performs better than other state-of-the-art methods with results suggesting better generalization capability.

MONITORING OF POSTURE ALLOCATIONS AND ACTIVITIES BY A SHOE-BASED WEARABLE SENSOR
ABSTRACT
Monitoring of posture allocations and activities enables accurate estimation of energy expenditure and may aid in obesity prevention and treatment. At present, accurate devices rely on multiple sensors distributed on the body and thus may be too obtrusive for everyday use.
This paper presents a novel wearable sensor, which is capable of very accurate recognition of common postures and activities. The patterns of heel acceleration and plantar pressure uniquely characterize postures and typical activities while requiring minimal preprocessing and no feature extraction. The shoe sensor was tested in nine adults performing sitting and standing postures and while walking, running, stair ascent/descent and cycling.
Support vector machines (SVMs) were used for classification. A fourfold validation of a six-class subject-independent group model showed 95.2% average accuracy of posture/activity classification on full sensor set and over 98% on optimized sensor set.
Using a combination of acceleration/pressure also enabled a pronounced reduction of the sampling frequency (25 to 1 Hz) with out significant loss of accuracy (98% versus 93%). Subjects had shoe sizes (US) M9.5-11 and W7-9 and body mass index from 18.1 to 39.4 kg/m2 and thus suggesting that the device can be used by individuals with varying anthropometric characteristics.

A WEB-BASED SYSTEM FOR HOME MONITORING OF PATIENTS WITH PARKINSON'S DISEASE USING WEARABLE SENSORS
ABSTRACT
This letter introduces MercuryLive, a platform to enable home monitoring of patients with Parkinson's disease (PD) using wearable sensors. MercuryLive contains three tiers: a resource-aware data collection engine that relies upon wearable sensors, web services for live streaming and storage of sensor data, and a web-based graphical user interface client with video conferencing capability.
Besides, the platform has the capability of analyzing sensor (i.e., accelerometer) data to reliably estimate clinical scores capturing the severity of tremor, bradykinesia, and dyskinesia.
Testing results showed an average data latency of less than 400 ms and video latency of about 200 ms with video frame rate of about 13 frames/s when 800 kb/s of bandwidth were available and we used a 40% video compression, and data feature upload requiring 1 min of extra time following a 10 min interactive session.
These results indicate that the proposed platform is suitable to monitor patients with PD to facilitate the titration of medications in the late stages of the disease.

MAPPING AND PURSUIT-EVASION STRATEGIES FOR A SIMPLE WALL-FOLLOWING ROBOT
ABSTRACT
This paper defines and analyzes a simple robot with local sensors that moves in an unknown polygonal environment. The robot can execute wall-following motions and can traverse the interior of the environment only when following parallel to an edge.
The robot has no global sensors that would allow precise mapping or localization. Special information spaces are introduced for this particular model.
Using these, strategies are presented to solve several tasks:
1) counting vertices,
2) computing the path winding number,
3) learning a combinatorial map, which is called the cut ordering, that encodes partial geometric information, and
4) solving pursuit-evasion problems.

METHODS AND TECHNOLOGIES FOR THE IMPLEMENTATION OF LARGE-SCALE ROBOT TACTILE SENSORS
ABSTRACT
Even though the sense of touch is crucial for humans, most humanoid robots lack tactile sensing. While a large number of sensing technologies exist, it is not trivial to incorporate them into a robot. We have developed a compliant “skin” for humanoids that integrates a distributed pressure sensor based on capacitive technology.
The skin is modular and can be deployed on nonflat surfaces. Each module scans locally a limited number of tactile-sensing elements and sends the data through a serial bus. This is a critical advantage as it reduces the number of wires.
The resulting system is compact and has been successfully integrated into three different humanoid robots. We have performed tests that show that the sensor has favorable characteristics and implemented algorithms to compensate the hysteresis and drift of the sensor. Experiments with the humanoid robot iCub prove that the sensors can be used to grasp unmodeled, fragile objects.

TWO-FLEXIBLE-FINGERS GRIPPER FORCE FEEDBACK CONTROL SYSTEM FOR ITS APPLICATION AS END EFFECTOR ON A 6-DOF MANIPULATOR
ABSTRACT
Flexible manipulators have many advantages over rigid robots when used in grasping tasks, owing to the characteristic flexibility of the materials used in their construction, which allow them to absorb energy during impact and make them controllable in order to limit the force applied during contact. In this paper, a two-flexible-finger gripper with a simple sensory feedback system is proposed.
A generalized proportional-integral controller is implemented to acquire high control accuracy, while eliminating the need for derivatives of system output. The performance of this force feedback control system is investigated when mounted on a 6-degree-of-freedom (6-DOF) manipulator and grasping different objects.
The experimental results indicate that the system proposed is able to manipulate different types of objects (both rigid and flexible) in an industrial environment by perfectly controlling the applied contact torque.

TOUCH-SCREEN TERMINAL APPLICATION FOR REMOTE DATA BASED ON AUTHORIZED ACCESS

ABSTRACT
Touch-screen all-in-one-machine is the simplest, most convenient and most natural human-computer interaction method as a new kind of computer input devices.
For the disadvantages of the current touch screen systems such as the relatively simple function of the system and the lack of security features, this paper proposes a common software interface, which makes use of B/S mode to realize the browsing of the remote data, provides the authorized access mechanism based on Web secure access control, and achieves classification access of the remote data.

GESTURE CONTROL AND THE NEW AND INTELLIGENT MAN-MACHINE INTERFACE
ABSTRACT
Summary form only given. Human-computer interfaces (HCI) have evolved from mouse-keyboard based interaction using text and mouse events to multi-touch screens and other exotic approaches such as using special gloves or other devices to translate human actions into application controls.
One of the trends which are “en vogue” in our days is the control of computer applications and/or computer controlled devices using human gestures and/or body movements. There were and still are a series of attempts to produce computer control scripts via gesture based interfaces, and research literature is abundant in papers on this subject.
However, little or few are of value, as the computer based control via gestures has to be robust and in real-time. Any lag in the result can lead to users abandoning it. More recently, 3D IR cameras provide a promised path to produce depth images. The depth information extracted by the 3D IR camera is mapped to different grey levels in a black and white image.
This image is finally interpreted by image processing suites. 3D IR cameras use near-infrared illumination, allowing objects that are closer to the camera to appear brighter than the rest. This means that computer vision software modules can much more accurately distinguish hands and fingers from the rest of a person's body, even in complete darkness.
In this talk, we will discuss various technologies to be used to build a 3D IR Camera, review which will be finalized with a discussion of the 3D IR Camera designed and implemented by our group. Based on data provided by the 3D IR Camera a series of related image processing applications will be discussed.
A demonstration, of a 3D IR camera system will be presented and applications related to gaming, learning, and immersion in a 3D virtual reality space will be given at the end.

The proposed methods are general and can be applied to a variety of applications. Finally, experimental results on real datasets from the DARPA-LAGR program are given to illustrate the effectiveness of the proposed approaches.

Finally, we present the construction and deployment of the sensor on a robot in both telepresence and autonomous operation.

DESIGN OF A POWER-ASSIST WHEELCHAIR FOR PERSONS WITH HEMIPLEGIA
ABSTRACT
Persons with hemiplegia often require a one arm drive wheelchair. Current designs exhibit substantially degraded performance when compared to a standard manual wheelchair. A power-assist, one arm drive wheelchair was developed that was maneuverable, foldable and easy to operate.
A motor powers the wheel on the user's affected side, encoders on both rear wheels track wheel positions and a rotary heel interface mounted on a footrest controls steering. A control system analyzes wheel and steering positions and responds to the motion of the hand-driven wheel.
The prototype met and exceeded predetermined design specifications based on standard industry test procedures. The power-assist components could be attached to a wide range of manual wheelchairs with only minimal modifications.

CONTROL LAYER FOR MULTI-VENDOR INDUSTRIAL ROBOT INTERACTION PROVIDING INTEGRATION OF SUPERVISORY PROCESS CONTROL AND MULTIFUNCTIONAL CONTROL UNITS
ABSTRACT
Based on recent industrial needs for a flexible integration of supervisory control systems and novel intuitive manual control units a new control layer is introduced. The control layer affords adaptive behaviour in terms of process and motion planning as well as flexible manual control of arbitrary robot controllers. It is located between the industrial robot controller and the control units.
For the purpose of a flexible manufacturer-independent access to the robot controller we define an object-oriented programming interface. The set of robot commands is manufacturer-independent and includes all basic robot functions regarding motion and program control.
An inherent capability of the control layer is the transformation of neutral object-oriented robot commands to manufacturer-specific robot languages. With an emphasis on the development of a flexible control layer, we aim for a media-independent communication solution. In order to cover a broad range of robotic applications, different communication standards of industrial automation are implemented.
Finally, two applications, a smartphone robot control and a distributed robot control system, are presented and discussed.

DYNAMIC MODELING AND ENERGY CONSUMPTION ANALYSIS OF CRAB WALKING OF A SIX-LEGGED ROBOT
ABSTRACT
In this paper, an attempt has been made to develop a detailed dynamic model of a realistic six-legged robot during its crab motion. An energy consumption model has been derived for statically stable wave-crab gaits after considering a minimum of dissipating energy for optimal feet forces distributions.
Two approaches, such as minimization of norm of feet forces and minimization of norm of joint torques have been developed. The performances of these approaches have been compared with each other for different values of duty factor.
The effects of walking parameters, namely velocity, stroke, duty factor and crab angle are studied on energy consumption during crab walking. Wave gait with a lower duty factor is found to be more energy-efficient compared to that with the higher duty factor at the highest possible velocity.

INTELLIGENT OBSTACLE AVOIDENCE SYSTEM DESIGN OF AN UNMANNED GROUND VEHICLE WITH STEREO VISION
ABSTRACT
The main theme of this paper is to develop a navigation vehicle system without GPS. With stereo vision, the geographic information ahead of the vehicle is obtained by the principle of plane induced parallax. The profiles of left and right vision are acquired by Canny Edge Detection algorithm.
Then, an intersection line of the obstacle and the level ground is found by the way of image processing. Finally, the position and distance of the obstacle is calculated by the homography matrix method.
Integrating the above-distributed schemes unmanned vehicle can avoid collisions with obstacles and arrive at the target in difference scenario. Experimental results show that the proposed navigation and control methodology are practicable.

WIND ESTIMATION AND AIRSPEED CALIBRATION USING A UAV WITH A SINGLE-ANTENNA GPS RECEIVER AND PITOT TUBE
ABSTRACT
This paper proposes a method that uses an aircraft with a single-antenna GPS receiver and Pitot tube to estimate wind speed and direction and to calibrate the airspeed. This sensor combination alone does not determine the true attitude of the aircraft, so the wind parameters cannot be obtained directly from the measurements.
However, if the aircraft flies at different headings, such as in banking turns or circle maneuvers, the wind magnitude and direction can be estimated from the geometrical relation between the wind and the measurements. An extended Kalman filter (EKF) is applied to estimate wind parameters.
The EKF can also estimate the scaling factor used to convert dynamic pressure to airspeed. This is useful for the operation of small unmanned aerial vehicles (UAVs) because of difficulty in determining the airspeed scaling factor of a low-cost UAV.
Simulations are performed for a constant 2-D wind. To test the effectiveness of the proposed method, flight tests of a small UAV are conducted. Simulations and flight test results show that the proposed method is effective.

A talking robot which adaptively learns the vocalization skill by an auditory feedback learning is being developed. The talking robot is constructed by the mechanical vocal systems, which respectively correspond to human organs.
In vocalization, the vibration of vocal cords generates a source sound, and then the sound wave is led to a vocal tract, which works as a resonance filter to determine the spectrum envelope.
The talking robot autonomously learns the vocalization by applying auditory feedback. In this study, a human-like expressive speech production by the talking robot is introduced. A human generates speech by controlling their own vocal organs for changing the speech expressions such as the volume and the intonations.
To realize the human-like expressive speech production, a control method for the mechanical organs has to be established. In the first part of the paper, the construction of the talking robot and the acquisition of the vocalization will be described, and then the control method for producing human-like speech with various expressions will be introduced.

A PATROLLING SCHEME IN WIRELESS SENSOR AND ROBOT NETWORKS
ABSTRACT
In this paper, we design a bio-inspired patrolling algorithm based on digital pheromone. As events have different importance, we refer to them as having different priorities.
In our patrolling schemes, robots efficiently handle as many high priority events as possible. Inspired by the pheromone-based communication among ants, we introduce the concept of digital pheromones and propose a digital pheromone-based patrolling algorithm.
Digital pheromones are introduced to denote the priority of an event. The main purpose of this algorithm is to lead robots to handle more events with higher priorities. Simulations demonstrate the impact of robots' patrol speed, speed of robots' handling events, etc.

DYNAMIC VEHICLE ROUTING FOR ROBOTIC SYSTEMS
ABSTRACT
Recent years have witnessed great advancements in the science and technology of autonomy, robotics and networking. This paper surveys recent concepts and algorithms for dynamic vehicle routing (DVR), that is, for the automatic planning of optimal multi-vehicle routes to perform tasks that are generated over time by an exogenous process.
We consider a rich variety of scenarios relevant for robotic applications. We begin by reviewing the basic DVR problem: demands for service arrive at random locations at random times and a vehicle travels to provide on-site service while minimizing the expected wait time of the demands.
Next, we treat different multi-vehicle scenarios based on different models for demands (e.g., demands with different priority levels and impatient demands), vehicles (e.g., motion constraints, communication and sensing capabilities), and tasks. The performance criterion used in these scenarios is either the expected wait time of the demands or the fraction of demands serviced successfully.
In each specific DVR scenario, we adopt a rigorous technical approach that relies upon methods from queueing theory, combinatorial optimization and stochastic geometry.
First, we establish fundamental limits on the achievable performance, including limits on stability and quality of service. Second, we design algorithms, and provide provable guarantees on their performance with respect to the fundamental limits.

SITUATION-DRIVEN CONTROL OF A ROBOTIC WHEELCHAIR TO FOLLOW A CAREGIVER
ABSTRACT
Recently, several robotic/intelligent wheelchairs that have autonomous functions to get to some goals or user-friendly interfaces, have been proposed. Although it is desirable for wheelchair users to go out alone, caregivers often accompany them.
Therefore it is important to consider reducing caregivers' load and support their activities. Hence, we have proposed a robotic wheelchair that can move with a caregiver side by side by observing his/her behaviors such as body position and orientation.
This way of motion enables easy communication between the wheelchair user and the caregiver. However, caregivers cannot always move with the wheelchair side by side. For instance, they may step forward of the wheelchair to open a door, and they may step aside when pedestrians are approaching in narrow corridors.
To cope with these situations we propose a new robotic wheelchair that can move with a caregiver collaboratively depending on the situation. A laser range sensor is used for observing the environment around the wheelchair. When any obstacles are found in its travelling direction, the wheelchair gives up moving with the caregiver side by side and follows him/her behind. When the caregiver stops at a door, the wheelchair waits for him/her to open the door and follows him/her while avoiding obstacles.
The wheelchair returns to move side by side with the caregiver when it enters wide space. We propose a motion control method based on the potential field method, which enables the wheelchair to take an appropriate position with respect to the caregiver depending on the situation.

SELF-PACED BRAIN-CONTROLLED WHEELCHAIR METHODOLOGY WITH SHARED AND AUTOMATED ASSISTIVE CONTROL
The consistency and reliability of the brain computer interface (BCI) system is often questioned to be safe for controlling a wheelchair as BCIs characteristically experience a low signal-to-noise ratio and low classification accuracy.
Electroencephalogram (EEG) acquired non-invasively consists of multiple time-series which are highly correlated because of volume conduction and ambient noises, thus providing a rather blurred image of the brain activity. This low signal-to-noise ratio and low spatial resolution of the data can degrade the translational performance of the BCI.
To overcome the low classification accuracy and the uncertainty in commands of the BCI systems, the user has to impart additional concentration and time to navigate the wheelchair to the desired location.
This paper presents a brain-controlled wheelchair (BCW) control strategy that reduces the total time required to complete a task and the concentration effort imparted by the user.
Two BCW approaches are investigated in this work; a synchronous BCW and a self-paced BCW. These methodologies involve a shared control methodology between the BCI/user component and the automated assistive control (AAC) component.
The proposed BCW strategies are compared to state-of-the-art BCW control methodologies available in the literature. The results show that the proposed methods not only reduce the concentration time but also provide a safer and reliable control compared to other BCWs.

PATH FOLLOWING SYSTEM OF SMALL UNMANNED AUTONOMOUS VEHICLE FOR SURVEILLANCE APPLICATION
ABSTRACT
A path following flight control is developed to be implemented in a small UAV system. The path following control is designed such that the UAV is able to follow smooth flight-paths within its maneuvering capabilities.
Payload space, weight, and power source constraints dictate the system to be designed with limited application of sensors and actuators, while it is still required to be able to perform its mission within a predefined measures. The control scheme is intended to be able to steer the UAV flight close to a predefined path and control its heading angle accordingly.
The controller principally works by driving the cross-track and course angle errors of the UAV flight, relative to the desired path, to zero, through performing Bank to Turn (BTT) maneuvers. The system generates corrective commands based on the error information and transforms it into a heading change via roll maneuver.
The roll maneuver controller is designed using LQR technique such that it can provide an appropriate roll dynamics of the UAV. Simulation results will be presented and analyzed to investigate the performance of the proposed system.

A TRANSFORMERLESS MEDIUM-VOLTAGE STATCOM TOPOLOGY BASED ON EXTENDED MODULAR MULTILEVEL CONVERTERS
ABSTRACT
A new transformerless four-leg topology is suggested for shunt compensation, the modular multilevel converters (MMC) based on the half-bridge converters, to achieve higher performance as a STATCOM in a distorted and unbalanced medium-voltage large-current (MV-LC) system.
Further, an extended MMC (EMMC) is proposed in order to manage more accurate compensation for high-power applications. Both proposals can be controlled for various purposes such as reactive power and unbalance compensation, voltage regulation, and harmonic cancellation. Moreover, related control strategies are also suggested for both the MMC and the EMMC to ensure that the source-end three-phase currents are sinusoidal and balanced. Also, the dc-link capacitors of the half-bridge converters are regulated.
One interesting application for the EMMC-based STATCOM could be the improvement in power quality and performance of the electrified railway traction power supply system.
Both the MMC- and the EMMC-based STATCOM along with their proposed control strategies were simulated; further, to verify the suggestions, these proposals were also implemented on a 30-kVA modular laboratory prototype. Experiments and simulations confirm the predefined objectives.

AN INTEGRATED-CONTROLLED AC/DC INTERFACE FOR MICROSCALE WIND POWER GENERATION SYSTEMS
ABSTRACT
In this paper, a novel ac/dc interface with an integrated controller is proposed for the microscale wind power generation system (WPGS). The proposed interface is mainly composed of a dynamic maximum power point tracking (MPPT) control and a half-controlled single-stage rectifier with an integrated control.
The half-controlled single-stage rectifier is proposed to replace the widely used two-stage converter for improving the current total harmonics distortion (THD) as well as the efficiency. The analytic expressions of the duty ratios for controlling the rectifier are also derived.
Moreover, the dynamic response of the wind turbine and the extracted wind power are enhanced by the integrated dynamic MPPT control. Finally, from the experimental results, it can be seen that the current THD is reduced to around 5%, and the total efficiency is increased by about 12%-15% depending on the wind speed variations.

A NEW SINGLE-PHASE SOFT-SWITCHING POWER FACTOR CORRECTION CONVERTER
ABSTRACT
In this paper, single-phase soft-switching power factor correction (PFC) circuit is developed with a new active snubber cell. This active snubber cell provides zero-voltage transition turn ON and zero-current transition turn OFF for the main switch without any extra current or voltage stresses.
Auxiliary switch is turned ON and OFF with zero-current switching (ZCS) without additional voltage stress. Although, there is a current stress on the auxiliary switch, it is decreased by diverting a part of the current to the output side with coupling inductance.
The output current and voltage are controlled by the proposed PFC converter in very wide line and load range. This PFC converter has simple structure, low cost, and ease of control as well.
In this study, a detailed steady-state analysis of the new converter is presented, and this theoretical analysis is verified exactly by 100 kHz and 300 W prototypes. This prototype has 98% total efficiency and 0.99 power factor with sinusoidal current shape.

A REAL MAXIMUM POWER POINT TRACKING METHOD FOR MISMATCHING COMPENSATION IN PV ARRAY UNDER PARTIALLY SHADED CONDITIONS
ABSTRACT
Conventional popular maximum power point tracking (MPPT) methods are effective under uniform solar irradiance. However, under solar irradiance mismatching conditions [partially shaded conditions (PSCs)], these MPPTs can fail for real MPPT (RMPPT), because multiple local maxima can be exhibited on the power-voltage characteristic curve.
Although some researchers have worked on RMPPT under partial shading conditions, the methods have some drawbacks in terms of complexity and requirements for additional circuits, etc. In this paper, a novel MPPT method capable of RMPPT under PSCs is proposed.
The performance of the proposed MPPT method is analyzed according to the RMPP position and is verified by simulation and experimental results.

A MINIMUM POWER-PROCESSING-STAGE FUEL-CELL ENERGY SYSTEM BASED ON A BOOST-INVERTER WITH A BIDIRECTIONAL BACKUP BATTERY STORAGE
ABSTRACT
When low-voltage unregulated fuel-cell (FC) output is conditioned to generate ac power, two stages are required: a boost stage and an inversion one. In this paper, the boost-inverter topology that achieves both boosting and inversion functions in a single stage is used to develop an FC-based energy system that offers high conversion efficiency, low-cost, and compactness.
The proposed system incorporates additional battery-based energy storage and a dc-dc bidirectional converter to support instantaneous load changes. The output voltage of the boost-inverter is voltage-mode controlled and the dc-dc bidirectional converter is current-mode controlled.
The load low-frequency current ripple is supplied by the battery, which minimizes the effects of such ripple being drawn directly from the FC itself. Analysis, simulation, and experimental results are presented to confirm the operational performance of the proposed system.

A HIGH POWER DENSITY SINGLE-PHASE PWM RECTIFIER WITH ACTIVE RIPPLE ENERGY STORAGE
ABSTRACT
It is well known that single-phase pulse width modulation rectifiers have second-order harmonic currents and corresponding ripple voltages on the dc bus. The low-frequency harmonic current is normally filtered using a bulk capacitor in the bus, which results in low power density.
However, pursuing high power density in converter design is a very important goal in the aerospace applications. This paper studies methods for reducing the energy storage capacitor for single-phase rectifiers.
The minimum ripple energy storage requirement is derived independently of a specific topology. Based on the minimum ripple energy requirement, the feasibility of the active capacitor's reduction schemes is verified.
Then, we propose a bidirectional buck-boost converter as the ripple energy storage circuit, which can effectively reduce the energy storage capacitance. The analysis and design are validated by simulation and experimental results.

INTELLIGENT ONLINE MEASUREMENT AND MANAGEMENT OF ENERGY METER DATA THROUGH ADVANCED WIRELESS NETWORK
ABSTRACT
Recently the Electrical supply companies are trying to adopt the electronic measurement of energy consumption data because of reduced manufacturing cost, improved measurement accuracy, increased timely information, miniature size and many other benefits that go well beyond the traditional rotor-plate energy meter type.
In this paper with the help of an energy chip, an improved energy metering solution is developed, where automating the progression of measurement through digital wireless communication technique is adopted to get the above benefits along with smooth control. The developed energy meter calculates the total average active power mainly for residential consumers.
The hardware circuit accepts single phase voltage and currents as its inputs and provides the output in the form of logic data proportional to the average real power.
This data is fed to a remote computer server through the wireless ZigBee network that represents the concept of distant wireless metering, practically involving no manpower. This paper also presents a software solution developed for total electrical energy billing and data management system.

FAULT-TOLERANT TORQUE CONTROL OF BLDC MOTORS
ABSTRACT
Fault tolerance is critical for servomotors used in high-risk applications, such as aerospace, robots, and military. These motors should be capable of continued functional operation, even if insulation failure or open-circuit of a winding occur.
This paper presents a fault-tolerant (FT) torque controller for brushless dc (BLdc) motors that can maintain accurate torque production with minimum power dissipation, even if one of its phases fails. The distinct feature of the FT controller is that it is applicable to BLdc motors with any back-electromotive-force waveform.
First, an observer estimates the phase voltages from a model based on Fourier coefficients of the motor waveform. The faulty phases are detected from the covariance of the estimation error. Subsequently, the phase currents of the remaining phases are optimally reshaped so that the motor accurately generates torque as requested while minimizing power loss subject to maximum current limitation of the current amplifiers.
Experimental results illustrate the capability of the FT controller to achieve ripple-free torque performance during a phase failure at the expenses of increasing the mean and maximum power loss by 28% and 68% and decreasing the maximum motor torque by 49%.

FINGERID: A NEW SECURITY MODEL BASED ON FINGERPRINT RECOGNITION FOR DISTRIBUTED SYSTEMS
ABSTRACT
The current practice of password based security for distributed systems in general and the Internet in particular is inadequate. Besides, remembering a plethora of long passwords and pass phrases sometimes as many as 15 or 20 is cumbersome.
This raises the need to introduce a better and more reliable authentication mechanism which is not dependent on a series of characters, but rather on a technology that is unique and only possessed by the individual. Similar services already exist, and they are good in some situations, but prove to be inadequate under other circumstances.
Overall, three main requirements of the everyday Internet user remain unaddressed – freedom from memorizing many passwords and pass phrases; convenience and ease of use; and security.
The present paper attempts to offer an answer to all these problems by just one solution, named FingerID. The contribution of this study is of considerable significance, as it would revolutionize the way Internet security is managed.

HIGH-EFFICIENCY REGULATION METHOD FOR A ZERO-CURRENT AND ZERO-VOLTAGE CURRENT-FED PUSH–PULL CONVERTER
ABSTRACT
A new high-efficiency regulation method for a zero-current and zero-voltage current-fed push-pull converter is presented. The method proposed is based on the use of a controlled transformer as a post-regulator, which adds or subtracts an additional voltage to the output filter of the converter.
An auxiliary regulator, which only handles a percentage of the output power, controls this transformer, and therefore, results in much higher efficiency than a normal preregulator would have. The novelty of the presented converter is that regulation is achieved without affecting the zero-voltage and zero-current switching in any working conditions.
Small- and large-signal models of the converter have been developed and a low-power prototype has been simulated and implemented. The good agreement, between the experimental simulations and theoretical results, validates the theoretical developments.

DYNAMIC MODELING AND ENERGY CONSUMPTION ANALYSIS OF CRAB WALKING OF A SIX-LEGGED ROBOT
ABSTRACT
The superior terrain adaptability and maneuverability characteristics of multi-legged robots compared to wheeled or tracked vehicles for off-road locomotion motivated the development of six-legged walking robots.
Six-legged robot might be used for locating and disarming bombs, extinguishing fires, underground mining to recover natural resources, explorations of ocean floors and planets, and others, where a human cannot sustain or which would be dangerous for him/her. However, with today’s technologies, the legged systems have the disadvantages of pay load to weight ratio, and poor energy efficiency.
An autonomous walking robot cannot function satisfactorily with a poor energy efficiency, due to the fact that it has to carry all driving and control units in addition to payload and trunk body. Long duration missions are also subjected to power supply constraints.
The minimization of energy consumption plays a key role in the design of an autonomous multi-legged robot. Various approaches are available in the literature to obtain energy-efficient gaits of multi-legged robots

BRAIN-ACTUATED HUMANOID ROBOT NAVIGATION CONTROL USING ASYNCHRONOUS BRAIN-COMPUTER INTERFACE
ABSTRACT
Brain-actuated robotic systems have been proposed as a new control interface to translate different human intentions into appropriate motion commands for robotic applications. This study proposes a brain-actuated humanoid robot navigation system that uses an EEG-BCI.
The experimental procedures consisted of offline training sessions, online feedback test sessions, and real-time control sessions. During the offline training sessions, amplitude features from the EEGs were extracted using band power analysis, and the informative feature components were selected using the Fisher ratio and the linear discriminant analysis (LDA) distance metric.
The Intentional Activity Classifier (IAC) and the Motor Direction Classifier (MDC) were hierarchically structured and trained to build an asynchronous BCI system.
During the navigation experiments, the subject controlled the humanoid robot in an indoor maze using the BCI system with real-time images from the camera on the robot's head. The results showed that three subjects successfully navigated the indoor maze using the proposed brain-actuated humanoid robot navigation system.

CONTROLLING HUMAN ATTENTION THROUGH ROBOT'S GAZE BEHAVIORS
ABSTRACT
Controlling someone's attention can be defined as shifting his/her attention from the existing direction to another. However, it is not easy task for a robot to shift a particular human's attention if they are not in face-to-face situation.
If the robot would like to communicate a particular person, it should turn its gaze to that person and make eye contact to establish mutual gaze. However, only such a turning action is not enough to set up eye contact when the robot and the target person are not facing each other.
Therefore, the robot should perform some actions so that it can attract the target person and meet their gaze. In this paper, we present a robot that can attract a target person's attention by moving its head, make eye contact through showing gaze awareness by blinking its eyes, and establish joint attention by repeating its head turns from the person and the target object.
Experiments using twenty human participants confirm the effectiveness of the robot actions to control human attention

DESIGN AND IMPLEMENTATION OF PYROELECTRIC INFRARED SENSOR BASED SECURITY SYSTEM USING MICROCONTROLLER
ABSTRACT
This paper evaluates the development of a Low-cost security system using small PIR (Pyroelectric Infrared) sensor built around a microcontroller. The low-power PIR detectors take advantage of pyroelectricity to detect a human body that is a constant source of Passive Infrared (radiation in the infrared region).
The system senses the signal generated by PIR sensor detecting the presence of individuals not at thermal equilibrium with the surrounding environment. Detecting the presence of any unauthorized person in any specific time interval, it triggers an alarm & sets up a call to a predefined number through a GSM modem.
This highly reactive approach has low computational requirement, therefore it is well-suited to surveillance, industrial applications and smart environments. Tests performed gave promising results.

THE IMPLEMENTATION OF THE INTELLIGENT TRANSPORT SYSTEM FOR THE REAL-TIME ROADSIDE ENVIRONMENT INFORMATION TRANSFER
ABSTRACT
The paper proposed a novel system “RTCS (Real-Time Control System for road environment)” to prevent accidents of drivers. This paper deployed sensors on roads and used these sensors to collect information to coordinators. How to use sensors to prevent accidents in vehicular environment is an interesting issue.
Vehicles are equipped with OBU (On-Board Unit) and use the OBU to query information if the coordinator or RSU (Road-Side Unit) is located in its communication range. This system also distributed events into different priority due to the different damages.
For your example, RSU collects and analyzes the roadside information for the driver's safety and which provides to an OBU and a management system according to the service priority. In the higher rank terminal, the developed IP-based set-top box application provides information such as the traffic information, road environmental information, environmental sensor station error, and etc.
The system has a high potential to improve traffic in two ways. First, it collects local environmental data and passes it to a central facility to further process it and pass it to vehicles. Second, it takes care that urgent local information is passed directly and thus quickly to local vehicles which increases traffic safety.
The paper presents architecture to connect a USN (Ubiquitous Sensor Network) with the ITS (Intelligent Transport System) consisting of connected OBU and RSU. The goal of the system is to provide the ITS with local environmental data gathered by the USN nodes.

THE INTELLIGENT EMBEDDED CONTROL WARNING SYSTEM FOR CAR REVERSING
ABSTRACT
Most of the car drivers used the reverse radar or a reverse camera to detect the road situation behind the vehicle when it is engaged in reverse gear. As a matter of fact, the pedestrians can virtually know if the vehicle is backing up or not only by seeing the permanent bright reverse lamps. And as there is not much change with the reverse lamp to be seen, therefore their warning function for pedestrians seems to be still insufficient eventually.
Therefore, this research tries to design a set of embedded intelligent car backup warning system so as to promote the safety of the walkers or the other drivers on the road. This embedded system uses Microsoft Win CE operating system and matches with the Mini2440 developing board. It also uses the Visual Studio 2005 for developing the intelligent touch panel operating mode.
The UART interface on the Mini 2440 developing board controls the frequency converter, RC server and LED by using PIC16F877 to transform the signal of the sensors.

THREE-PHASE TO SINGLE-PHASE POWER-CONVERSION SYSTEM
ABSTRACT
A power-conversion system for converting three-phase power into single-phase power is proposed in this paper. The proposed three-phase to single-phase (3f/1f) power-conversion system comprises a power converter, a zero-sequence transformer set, and a filter capacitor.
The output currents of the power converter are divided into two parts. One is a set of positive-sequence sinusoidal currents, whose phases are in phase with the voltages of the three-phase power source. The positive-sequence sinusoidal currents are employed to absorb a real power from the three-phase power source.
In addition, the power converter can perform the functions of three-phase balance, low harmonic distortion, and unity power factor when the single-phase load is used. The other is a set of zero-sequence currents, which will pass through the zero-sequence transformer set and build a single-phase voltage with high power quality for the single-phase load.
Since the proposed 3f/1f power-conversion system contains only one power converter, it has the advantages of simplifying both the power circuit and control circuit. A prototype is developed and tested to demonstrate the performance of the proposed 3f/1f power-conversion system.
The experimental results show that the proposed system can achieve the expected performance.

MULTIPHASE DC–DC CONVERTERS USING A BOOST-HALF-BRIDGE CELL FOR HIGH-VOLTAGE AND HIGH-POWER APPLICATIONS
ABSTRACT
In this paper, multiphase dc-dc converters are proposed for high-voltage and high-power applications. A generalized converter is configured such that the boost-half-bridge (BHB) cells and voltage doublers are connected in parallel or in series to increase the output voltage and/or the output power.
In addition to reduced device voltage and current ratings by the connection, the proposed converter has the following features: high-step-up voltage gain with significantly reduced transformer turn ratio, low-input current ripple due to interleaving effect, zero-voltage switching turn-ON of switches and zero-current switching turn-OFF of diodes, no additional clamping and start-up circuits required, high-component availability and easy thermal distribution due to the use of multiple small components, and flexibility in device selection resulting in optimized design.
A design guideline of determining the optimum circuit configuration for given output voltage and power level is presented. Experimental results are also provided to validate the proposed concept.

ONLINE VOTING SYSTEM POWERED BY BIOMETRIC SECURITY USING STEGANOGRAPHY
ABSTRACT
Using Cryptography and Steganography at the same time, we try to provide Biometric as well as Password security to voter accounts. The scheme uses images as cover objects for Steganography and as keys for Cryptography. The key image is a Biometric measure, such as a fingerprint image.
Proper use of Cryptography greatly reduces the risks in these systems as the hackers have to find both secret key and the template. The basic idea is to merge the secret key with the cover image on the basis of key image.
The result of this process produces a stego image which looks quite similar to the cover image but not detectable by human eye. The system targets the authentication requirement of a voting system.

SINGLE-PHASE BACK-TO-BACK CONVERTER FOR ACTIVE POWER BALANCING, REACTIVE POWER COMPENSATION, AND HARMONIC FILTERING IN TRACTION POWER SYSTEM
ABSTRACT
An active power compensator (APC) based on single-phase back-to-back power converter is proposed in this paper to solve problems of power quality of electric railway power supply system. This system adopts a single-phase feeding connection, which is called cophase power supply scheme.
In this scheme, APC connects the balance transformer between feeding phase for power supply and another phase for compensation. It has some characteristics, such as active power balancing, reactive power compensating, and harmonics filtering. In order to achieve these characteristics, the control scheme requires seven combination models. In this paper, a multifunctional control algorithm is proposed to realize every conceivable model.
A cophase system with APC based on field programmable gate array (FPGA) and YNvd balance transformer is also designed and evaluated. The experimental results obtained from this prototype illustrate that the compensating ability is extremely high in steady-state and dynamic responses, and the power quality of a substation with distorted loads can be improved integrally.

HIGH-EFFICIENCY REGULATION METHOD FOR A ZERO-CURRENT AND ZERO-VOLTAGE CURRENT-FED PUSH–PULL CONVERTER
ABSTRACT
A new high-efficiency regulation method for a zero-current and zero-voltage current-fed push-pull converter is presented. The method proposed is based on the use of a controlled transformer as a post-regulator, which adds or subtracts an additional voltage to the output filter of the converter.
An auxiliary regulator, which only handles a percentage of the output power, controls this transformer, and therefore, results in much higher efficiency than a normal preregulator would have. The novelty of the presented converter is that regulation is achieved without affecting the zero-voltage and zero-current switching in any working conditions.
Small- and large-signal models of the converter have been developed and a low-power prototype has been simulated and implemented. The good agreement, between the experimental simulations and theoretical results, validates the theoretical developments.

FAULT-TOLERANT TORQUE CONTROL OF BLDC MOTORS
ABSTRACT
Fault tolerance is critical for servomotors used in high-risk applications, such as aerospace, robots, and military. These motors should be capable of continued functional operation, even if insulation failure or open-circuit of a winding occur.
This paper presents a fault-tolerant (FT) torque controller for brushless dc (BLdc) motors that can maintain accurate torque production with minimum power dissipation, even if one of its phases fails. The distinct feature of the FT controller is that it is applicable to BLdc motors with any back-electromotive-force waveform.
First, an observer estimates the phase voltages from a model based on Fourier coefficients of the motor waveform.
The faulty phases are detected from the covariance of the estimation error. Subsequently, the phase currents of the remaining phases are optimally reshaped so that the motor accurately generates torque as requested while minimizing power loss subject to maximum current limitation of the current amplifiers.
Experimental results illustrate the capability of the FT controller to achieve ripple-free torque performance during a phase failure at the expenses of increasing the mean and maximum power loss by 28% and 68% and decreasing the maximum motor torque by 49%.

DYNAMIC MODELING AND ENERGY CONSUMPTION ANALYSIS OF CRAB WALKING OF A SIX-LEGGED ROBOT
ABSTRACT
In this paper, an attempt has been made to develop a detailed dynamic model of a realistic six-legged robot during its crab motion. An energy consumption model has been derived for statically stable wave-crab gaits after considering a minimum of dissipating energy for optimal feet forces distributions.
Two approaches, such as minimization of norm of feet forces and minimization of norm of joint torques have been developed. The performances of these approaches have been compared with each other for different values of duty factor.
The effects of walking parameters, namely velocity, stroke, duty factor and crab angle are studied on energy consumption during crab walking. Wave gait with a lower duty factor is found to be more energy-efficient compared to that with the higher duty factor at the highest possible velocity.

VOLTAGE-SOURCE PWM RECTIFIER–INVERTER BASED ON DIRECT POWER CONTROL AND ITS OPERATION CHARACTERISTICS
ABSTRACT
This paper describes a novel control strategy of direct power-control-based voltage-source pulsewidth modulation (PWM) rectifier-inverter. The key of this strategy is direct selection of a switching state of the PWM rectifier-inverter on basis of instantaneous power errors.

As a result, unity power factor operation is achieved by the proposed method, and the output currents are confirmed to be sinusoidal waveforms without large distortion under balanced and unbalanced power-source condition.

SENSORLESS VECTOR CONTROL OF INDUCTION MOTORS AT VERY LOW SPEED USING A NONLINEAR INVERTER MODEL AND PARAMETER IDENTIFICATION
ABSTRACT
The performance of vector-controlled induction motor drives without a speed sensor is generally poor at very low speed. The reasons are offset and drift components in the acquired feedback signals, voltage distortions caused by the nonlinear behavior of the switching converter, and the increased sensitivity against model parameter mismatch.
New modeling and identification techniques are proposed to overcome these problems. A pure integrator is employed for stator flux estimation which permits high-estimation bandwidth. Compensation of the drift components is done by offset identification.
The nonlinear voltage distortions are corrected by a self-adjusting inverter model. A further improvement is a novel method for online adaptation of the stator resistance. Experiments demonstrate smooth steady-state operation and high dynamic performance at extremely low speed.

BI-DIRECTIONAL DCM DC TO DC CONVERTER FOR HYBRID ELECTRIC VEHICLES
ABSTRACT
This paper presents a bi-directional DC to DC converter with a unique concept in control. The converter was designed for hybrid electric vehicles, so size becomes a pressing design parameter. For that reason a buck converter in DCM was used to realize the DC to DC converter.

A NEW ADAPTIVE WEIGHT ALGORITHM FOR SALT AND PEPPER NOISE REMOVAL
ABSTRACT
A new adaptive weight algorithm is developed for the removal of salt and pepper noise. It consists of two major steps, first to detect noise pixels according to the correlations between image pixels, then use different methods based on the various noise levels.
For the low noise level, neighborhood signal pixels mean method is adopted to remove the noise, and for the high noise level, an adaptive weight algorithm is used.
Experiments show the proposed algorithm has advantages over regularizing methods in terms of both edge preservation and noise removal, even for heavily contaminated image with noise level as high as 90%, it still can get a significant performance.

REMOVAL OF HIGH DENSITY SALT AND PEPPER NOISE THROUGH MODIFIED DECISION BASED UNSYMMETRIC TRIMMED MEDIAN FILTER
ABSTRACT
A modified decision based unsymmetrical trimmed median filter algorithm for the restoration of gray scale, and color images that are highly corrupted by salt and pepper noise is proposed in this paper.
The proposed algorithm replaces the noisy pixel by trimmed median value when other pixel values, 0's and 255's are present in the selected window and when all the pixel values are 0's and 255's then the noise pixel is replaced by mean value of all the elements present in the selected window.
This proposed algorithm shows better results than the Standard Median Filter (MF), Decision Based Algorithm (DBA), Modified Decision Based Algorithm (MDBA), and Progressive Switched Median Filter (PSMF).
The proposed algorithm is tested against different grayscale and color images and it gives better Peak Signal-to-Noise Ratio (PSNR) and Image Enhancement Factor (IEF).

ADIABATIC TECHNIQUE FOR ENERGY EFFICIENT LOGIC CIRCUITS DESIGN
ABSTRACT
The Energy dissipation in conventional CMOS circuits can be minimized through adiabatic technique. By adiabatic technique dissipation in PMOS network can be minimized and some of energy stored at load capacitance can be recycled instead of dissipated as heat.

In analysis, two logic families, ECRL (Efficient Charge Recovery Logic) and PFAL (Positive Feedback Adiabatic Logic) are compared with conventional CMOS logic for inverter and 2:1 multiplexer circuits. It is find that adiabatic technique is good choice for low power application in specified frequency range.

Carry Select Adder (CSLA) is one of the fastest adders used in many data-processing processors to perform fast arithmetic functions. From the structure of the CSLA, it is clear that there is scope for reducing the area and power consumption in the CSLA.
This work uses a simple and efficient gate-level modification to significantly reduce the area and power of the CSLA. Based on this modification 8-, 16-, 32-, and 64-b square-root CSLA (SQRT CSLA) architecture have been developed and compared with the regular SQRT CSLA architecture.
The proposed design has reduced area and power as compared with the regular SQRT CSLA with only a slight increase in the delay. This work evaluates the performance of the proposed designs in terms of delay, area, power, and their products by hand with logical effort and through custom design and layout in 0.18-$mu$m CMOS process technology. The results analysis shows that the proposed CSLA structure is better than the regular SQRT CSLA.

A PIPELINE VLSI ARCHITECTURE FOR HIGH-SPEED COMPUTATION OF THE 1-D DISCRETE WAVELET TRANSFORM
ABSTRACT
In this paper, a scheme for the design of a high-speed pipeline VLSI architecture for the computation of the 1-D discrete wavelet transform (DWT) is proposed. The main focus of the scheme is on reducing the number and period of clock cycles for the DWT computation with little or no overhead on the hardware resources by maximizing the inter- and intrastage parallelisms of the pipeline.
The interstage parallelism is enhanced by optimally mapping the computational load associated with the various DWT decomposition levels to the stages of the pipeline and by synchronizing their operations. The intrastage parallelism is enhanced by decomposing the filtering operation equally into two subtasks that can be performed independently in parallel and by optimally organizing the bitwise operations for performing each subtask so that the delay of the critical data path from a partial-product bit to a bit of the output sample for the filtering operation is minimized.
It is shown that an architecture designed based on the proposed scheme requires a smaller number of clock cycles compared to that of the architectures employing comparable hardware resources. In fact, the requirement on the hardware resources of the architecture designed by using the proposed scheme also gets improved due to a smaller number of registers that need to be employed.
Based on the proposed scheme, a specific example of designing an architecture for the DWT computation is considered. In order to assess the feasibility and the efficiency of the proposed scheme, the architecture thus designed is simulated and implemented on a field-programmable gate-array board.
It is seen that the simulation and implementation results conform to the stated goals of the proposed scheme, thus making the scheme a viable approach for designing a practical and realizable architecture for real-time DWT computation.

DUAL STACK METHOD: A NOVEL APPROACH TO LOW LEAKAGE AND SPEED POWER PRODUCT VLSI DESIGN
ABSTRACT
The development of digital integrated circuits is challenged by higher power consumption. The combination of higher clock speeds, greater functional integration, and smaller process geometries has contributed to significant growth in power density. Scaling improves transistor density and functionality on a chip.
Scaling helps to increase speed and frequency of operation and hence higher performance. As voltages scale downward with the geometries threshold voltages must also decrease to gain the performance advantages of the new technology but leakage current increases exponentially.
Today leakage power has become an increasingly important issue in processor hardware and software design. In 65 nm and below technologies, leakage accounts for 30-40% of processor power.
In this paper, we propose a new dual stack approach for reducing both leakage and dynamic powers. Moreover, the novel dual stack approach shows the least speed power product when compared to the existing methods.

REMOVAL OF HIGH DENSITY SALT AND PEPPER NOISE THROUGH MODIFIED DECISION BASED UNSYMMETRIC TRIMMED MEDIAN FILTER
ABSTRACT
A modified decision based unsymmetrical trimmed median filter algorithm for the restoration of gray scale, and color images that are highly corrupted by salt and pepper noise is proposed in this paper.
The proposed algorithm replaces the noisy pixel by trimmed median value when other pixel values, 0's and 255's are present in the selected window and when all the pixel values are 0's and 255's then the noise pixel is replaced by mean value of all the elements present in the selected window.
This proposed algorithm shows better results than the Standard Median Filter (MF), Decision Based Algorithm (DBA), Modified Decision Based Algorithm (MDBA), and Progressive Switched Median Filter (PSMF).
The proposed algorithm is tested against different grayscale and color images and it gives better Peak Signal-to-Noise Ratio (PSNR) and Image Enhancement Factor (IEF).

A NEW ADAPTIVE WEIGHT ALGORITHM FOR SALT AND PEPPER NOISE REMOVAL
ABSTRACT
A new adaptive weight algorithm is developed for the removal of salt and pepper noise. It consists of two major steps, first to detect noise pixels according to the correlations between image pixels, then use different methods based on the various noise levels.
For the low noise level, neighborhood signal pixels mean method is adopted to remove the noise, and for the high noise level, an adaptive weight algorithm is used.
Experiments show the proposed algorithm has advantages over regularizing methods in terms of both edge preservation and noise removal, even for heavily contaminated image with noise level as high as 90%, it still can get a significant performance.

A MODIFIED WEIGHTED BASED FILTER FOR REMOVAL OF RANDOM IMPULSE NOISE (MWB)
ABSTRACT
In this paper an effort has been made to device an algorithm for highly corrupted images. In this paper a novel Modified Weighted Based(MWB) filter has been proposed, which is based on the weighted differences between the current pixel and its neighbors aligned with four main directions.
Simulations showed that the MWB filter provides optimal performances of suppressing impulse with high noise level which may enhance the performance in terms of removal of random-valued impulse noise compared to the directional weighted median (DWM) filter along with other filters like signal-dependent rank order mean (SDROM)filter, multistate median (MSM) filter, adaptive center weighted median (ACWM) filter, pixel-wise MAD(PWMAD) filter etc.

RANDOM IMPULSE NOISE REMOVAL FROM IMAGE SEQUENCES BASED ON FUZZY LOGIC
ABSTRACT
In this paper a new filter for image sequences corrupted with random impulse noise is presented. In order to preserve the image details as much as possible, the noise is removed in different successive filtering steps. In each step, only the pixels that are detected as being noisy are filtered, while the noise-free pixels remain unchanged.
The noise detection is based on fuzzy set theory and fuzzy rules, which are very useful for the processing of human knowledge and linguistic values. To exploit the temporal information in image sequences as much as possible, detected pixels are finally filtered in a motion compensated way.
From the experimental results it can be seen that the proposed method outperforms other state-of-the-art filters both in terms of the peak-signal-to-noise ratio, the mean absolute error, and visually.

POISSON NOISE REMOVAL FROM IMAGES USING THE FAST DISCRETE CURVELET TRANSFORM
ABSTRACT
We propose a strategy to combine the variance stabilizing transform (VST), used for Poisson image denoising, with the fast discrete Curvelet transform (FDCT). The VST transforms the Poisson image to approximately Gaussian distributed, and the subsequent denoising can be performed in the Gaussian domain. However, the performance of the VST degrades when the original image intensity is very low.
On the other hand, the FDCT can sparsely represent the intrinsic features of images having discontinuities along smooth curves. Therefore, it is suitable for denoising applications. Combining the VST with the FDCT leads to good Poisson image denoising algorithms, even for low intensity images.
We present a simple approach to achieve this and demonstrate some simulation results. The results show that the VST combined with the FDCT is a promising candidate for Poisson denoising.

MDS-BASED MULTIRESOLUTION NONLINEAR DIMENSIONALITY REDUCTION MODEL FOR COLOR IMAGE SEGMENTATION
ABSTRACT
In this paper, we present an efficient coarse-to-fine multiresolution framework for multidimensional scaling and demonstrate its performance on a large-scale nonlinear dimensionality reduction and embedding problem in a texture feature extraction step for the unsupervised image segmentation problem.
We demonstrate both the efficiency of our multiresolution algorithm and its real interest to learn a nonlinear low-dimensional representation of the texture feature set of an image which can then subsequently be exploited in a simple clustering-based segmentation algorithm.
The resulting segmentation procedure has been successfully applied on the Berkeley image database, demonstrating its efficiency compared to the best existing state-of-the-art segmentation methods recently proposed in the literature.

DISCRETE WAVELET TRANSFORM-BASED SATELLITE IMAGE RESOLUTION ENHANCEMENT
ABSTRACT
Satellite images are being used in many fields of research. One of the major issues of these types of images is their resolution. In this paper, we propose a new satellite image resolution enhancement technique based on the interpolation of the high-frequency subbands obtained by discrete wavelet transform (DWT) and the input image.
The proposed resolution enhancement technique uses DWT to decompose the input image into different subbands. Then, the high-frequency subband images and the input low-resolution image have been interpolated, followed by combining all these images to generate a new resolution-enhanced image by using inverse DWT.
In order to achieve a sharper image, an intermediate stage for estimating the high-frequency subbands has been proposed. The proposed technique has been tested on satellite benchmark images.
The quantitative (peak signal-to-noise ratio and root mean square error) and visual results show the superiority of the proposed technique over the conventional and state-of-art image resolution enhancement techniques.

WAVELET ENHANCED FUSION ALGORITHM FOR MULTISENSOR IMAGES
ABSTRACT
Due to the limitation of the image acquisition equipment itself and the constraints of taking environment and other factors, the resolution and contrast of the obtained images have declined, and some important information in the images was hidden in the acquisition process.
Therefore, in order to get a richer picture, the source images must be enhanced prior to the integration, so as to access the hidden information. The proposed paper introduces the general integration scheme based on image enhancement, and presents a fusion method with the wavelet image enhancement technology.
We first enhance the source images according to wavelet image enhancement technology, and then use the appropriate fusion rule to integrate the coefficients of the original images and the enhanced images.
Experimental results show that the enhancement of the source images prior to integration, could improve the fusion effect and obtain the hidden information barely acquired through directly fusion without enhancement.

A STEGANOGRAPHIC METHOD BASED ON INTEGER WAVELET TRANSFORM AND GENETIC ALGORITHM
ABSTRACT
This paper proposes a novel steganography scheme based on Integer Wavelet Transform and Genetic Algorithm. The novel scheme embeds data in integer wavelet transform coefficients by using a mapping function based on Genetic Algorithm in an 8 × 8 block on the cover image.
The optimal pixel adjustment process is applied after embedding the message. We employed frequency domain to increase the robustness of our steganography method. Integer wavelet transform avoids the floating point precision problems of the wavelet filter.
We use GA and Optimal Pixel Adjustment Process to obtain an optimal mapping function to reduce the difference error between the cover and the stego-image and to increase the hiding capacity with low distortions respectively.
Simulation results show that the novel scheme outperforms adaptive steganography technique based on integer wavelet transform in term of peak signal to noise ratio and capacity, 35.17 dB and 50% respectively.

SECURITY ANALYSIS ON SPATIAL 1 STEGANOGRAPHY FOR JPEG DECOMPRESSED IMAGES
ABSTRACT
Although many existing steganalysis works have shown that the spatial ±1 steganography on JPEG pre-compressed images is relatively easier to be detected compared with that on the never-compressed images, most experimental results seem not very convincing since these methods usually assume that the quantization table of the JPEG stegos previously used is known before detection and/or the length of embedded message is fixed.
Furthermore, there are just few effective quantitative algorithms for further estimating the spatial modifications. In this letter, we firstly propose an effective method to detect the quantization table from the contaminated digital images which are originally stored as JPEG format based on our recently developed work about JPEG compression error analysis, and then we present a quantitative method to reliably estimate the length of spatial modifications in those gray-scale JPEG stegos by using data fitting technology.
The extensive experimental results show that our estimators are very effective, and the order of magnitude of prediction error can remain around measured by the mean absolute difference.

ISOLATED WIND–HYDRO HYBRID SYSTEM USING CAGE GENERATORS AND BATTERY STORAGE
ABSTRACT
This paper deals with a new isolated wind-hydro hybrid generation system employing one squirrel-cage induction generator (SCIG) driven by a variable-speed wind turbine and another SCIG driven by a constant-power hydro turbine feeding three-phase four-wire local loads.
The proposed system utilizes two back-to-back-connected pulsewidth modulationcontrolled insulated-gate-bipolar-transistor-based voltage-source converters (VSCs) with a battery energy storage system at their dc link.
The main objectives of the control algorithm for the VSCs are to achieve maximum power tracking (MPT) through rotor speed control of a wind-turbine-driven SCIG under varying wind speeds and control of the magnitude and the frequency of the load voltage.
The proposed wind-hydro hybrid system has a capability of bidirectional active- and reactive-power flow, by which it controls the magnitude and the frequency of the load voltage.
The proposed electromechanical system using SCIGs, an MPT controller, and a voltage and frequency controller are modeled and simulated in MATLAB using Simulink and Sim Power System set toolboxes, and different aspects of the proposed system are studied for various types of linear, nonlinear, and dynamic loads, and under varying wind-speed conditions.
The performance of the proposed system is presented to demonstrate its capability of MPT, voltage and frequency control (VFC), harmonic elimination, and load balancing.

TECHNO-ECONOMIC ANALYSIS OF SVC-HVDC TRANSMISSION SYSTEM FOR OFFSHORE WIND
ABSTRACT
One of the trends concerning offshore wind farms is to increase the distance from the wind farm to the shore, and has to be transported over very long distances to make a connection with the main supply grid. But placing wind farms offshore rises a lot o challenges related to construction, installation and nevertheless with the energy transmission.
VSC HVDC is a rather new technology with promising characteristics for offshore wind transmission. And the techno-economic value analysis for VSC HVDC is necessary as all projects require a maximal effort in order to make the offshore wind farm viable. The possible structures for offshore wind farm and some feasible turbine topologies for offshore wind were introduced in the paper.
Based on the grid code requirements, a techno-economic analysis for VSC HVDC with SCIG was proposed. This HVDC system is compared to the main variable-speed topologies (DFIG and DDPMSG) in combination with HVAC and a typical wind farm is put upfront to investigate. Result show that the SVC HVDC transmission system with SCIC could get a cost-efficient.

GRID INTERCONNECTION OF RENEWABLE ENERGY SOURCES AT THE DISTRIBUTION LEVEL WITH POWER-QUALITY IMPROVEMENT FEATURES
ABSTRACT
Renewable energy resources (RES) are being increasingly connected in distribution systems utilizing power electronic converters. This paper presents a novel control strategy for achieving maximum benefits from these grid-interfacing inverters when installed in 3-phase 4-wire distribution systems.
The inverter is controlled to perform as a multi-function device by incorporating active power filter functionality. The inverter can thus be utilized as: 1) power converter to inject power generated from RES to the grid, and 2) shunt APF to compensate current unbalance, load current harmonics, load reactive power demand and load neutral current.
All of these functions may be accomplished either individually or simultaneously. With such a control, the combination of grid-interfacing inverter and the 3-phase 4-wire linear/non-linear unbalanced load at point of common coupling appears as balanced linear load to the grid.
This new control concept is demonstrated with extensive MATLAB/Simulink simulation studies and validated through digital signal processor-based laboratory experimental results.

A NEW APPROACH TO MULTIFUNCTIONAL DYNAMIC VOLTAGE RESTORER IMPLEMENTATION FOR EMERGENCY CONTROL IN DISTRIBUTION SYSTEMS
ABSTRACT
The dynamic voltage restorer (DVR) is one of the modern devices used in distribution systems to protect consumers against sudden changes in voltage amplitude. In this paper, emergency control in distribution systems is discussed by using the proposed multifunctional DVR control strategy.
Also, the multiloop controller using the Posicast and P+Resonant controllers is proposed in order to improve the transient response and eliminate the steady-state error in DVR response, respectively. The proposed algorithm is applied to some disturbances in load voltage caused by induction motors starting, and a three-phase short circuit fault. Also, the capability of the proposed DVR has been tested to limit the downstream fault current.
The current limitation will restore the point of common coupling (PCC) (the bus to which all feeders under study are connected) voltage and protect the DVR itself.
The innovation here is that the DVR acts as a virtual impedance with the main aim of protecting the PCC voltage during downstream fault without any problem in real power injection into the DVR. Simulation results show the capability of the DVR to control the emergency conditions of the distribution systems.

FLEXIBLE D-STATCOM PERFORMANCE AS A FLEXIBLE DISTRIBUTED GENERATION IN MITIGATING FAULTS
ABSTRACT
This paper proposes a flexible D-STATCOM (Distribution Static COMpensator) and its new controller system, that be able to both mitigate all types of faults and operate as a Distributed Generation (DG), when it supplies power to sensitive loads while the main utility source is disconnected (i.e. it is under islanded operating condition).
Thus D-STATCOM operates same as a flexible DG (FDG) and consequently, it is called Flexible D-STATCOM (FD-STATCOM). This paper validates the performance of FD-STATCOM system to mitigate power quality problems and improve distribution system performance under all types of system related disturbances and system unbalanced faults, such as Line-to-Line (LL) and Double Line to Ground (DLG) faults and supplies power to sensitive loads under islanding condition.
In this paper, the 12-pulse D-STATCOM configuration with IGBT is designed and the graphic based models of the D-STATCOM are developed using the PSCAD/EMTDC electromagnetic transient simulation program.
The reliability and robustness of the control schemes in the system response to the voltage disturbances caused by LL and DLG faults and islanded operating condition are obviously proved in the simulation results.

MATRIX CONVERTER-BASED UNIFIED POWER-FLOW CONTROLLERS ADVANCED DIRECT POWER CONTROL METHOD
ABSTRACT
This paper presents a direct power control (DPC) for three-phase matrix converters operating as unified power flow controllers (UPFCs). Matrix converters (MCs) allow the direct ac/ac power conversion without dc energy storage links; therefore, the MC-based UPFC (MC-UPFC) has reduced volume and cost, reduced capacitor power losses, together with higher reliability.
Theoretical principles of direct power control (DPC) based on sliding mode control techniques are established for an MC-UPFC dynamic model including the input filter. As a result, line active and reactive power, together with ac supply reactive power, can be directly controlled by selecting an appropriate matrix converter switching state guaranteeing good steady-state and dynamic responses.
Experimental results of DPC controllers for MC-UPFC show decoupled active and reactive power control, zero steady-state tracking error, and fast response times.
Compared to an MC-UPFC using active and reactive power linear controllers based on a modified Venturini high-frequency PWM modulator, the experimental results of the advanced DPC-MC guarantee faster responses without overshoot and no steady-state error, presenting no cross-coupling in dynamic and steady-state responses.

MODELING, ANALYSIS, AND CONTROL FOR THE RECTIFIER OF HYBRID HVDC SYSTEMS FOR DFIG-BASED WIND FARMS
ABSTRACT
In order to improve the dynamic performance of the hybrid HVdc system for doubly fed induction generator wind farms, this paper presents the modeling, analysis, and control methods for its line-commutated rectifier.
First, the state variable model of the rectifier subsystem on the reference frame is derived considering different control modes of the current source inverter subsystem. Then, the ac current dynamic of the rectifier subsystem is quantitatively analyzed based on the eigenvalue analysis method.
According to the analysis results, a double loop control scheme is designed: the inner loop utilizes the inverse system control technique plus a switchable phase-lead compensator, and the outer loop implements an ordinary propotional-integral controller.
Finally, the validity of the quantitative analysis method and the superiority of the proposed control scheme are verified by Simulink / SimPowerSystems simulations.

A 2.4-GHZ ENERGY-EFFICIENT TRANSMITTER FOR WIRELESS MEDICAL APPLICATIONS
Biomedical Circuits and Systems, IEEE Transactions on
ABSTRACT
A 2.4-GHz energy-efficient transmitter (TX) for wireless medical applications is presented in this paper. It consists of four blocks: a phase-locked loop (PLL) synthesizer with a direct frequency presetting technique, a class-B power amplifier, a digital processor, and nonvolatile memory (NVM).
The frequency presetting technique can accurately preset the carrier frequency of the voltage-controlled oscillator and reduce the lock-in time of the PLL synthesizer, further increasing the data rate of communication with low power consumption. The digital processor automatically compensates preset frequency variation with process, voltage, and temperature.
The NVM stores the presetting signals and calibration data so that the TX can avoid the repetitive calibration process and save the energy in practical applications. The design is implemented in 0.18- µm radio-frequency complementary metal-oxide semiconductor process and the active area is 1.3 mm 2.
The TX achieves 0-dBm output power with a maximum data rate of 4 Mb/s/2 Mb/s and dissipates 2.7-mA/5.4-mA current from a 1.8-V power supply for on-off keying/frequency-shift keying modulation, respectively. The corresponding energy efficiency is 1.2 nJ/b·mW and 4.8 nJ/b· mW when normalized to the transmitting power.

A DECISION-SUPPORT MODEL FOR FILTERING RFID READ DATA IN SUPPLY CHAINS
ABSTRACT
The introduction of radio-frequency identification (RFID) tags in supply chains engenders the need for incorporating and utilizing the additional generated data. It is generally assumed that these data, once generated, are complete and rife with necessary information for making decisions.
The reality is, however, that these data are not error free. Common errors observed in these data include false positives and false negatives. Given that these data are among the set of primary inputs for decision-making purposes, the read-rate accuracy is of paramount importance for effectively managing supply chains incorporating such data. Although there are means by which the RFID tag read rate could be improved to a certain extent, the errors in read rate cannot be completely eliminated, and decision makers are left to deal with such data while managing the supply chain.
We present and illustrate few algorithms that can be used to reduce false read rates. We consider models for filtering data that are already being gathered in RFID systems and utilize it to improve read-rate accuracy. We implement the proposed models and illustrate their performance.

A HYBRID WIRED/WIRELESS NETWORKING INFRASTRUCTUREFOR GREENHOUSE MANAGEMENT
This paper appears in: Instrumentation and Measurement, IEEE Transactions on
ABSTRACT
In this paper, the problems related to the management of a farm made up of several greenhouses are discussed. The management of this kind of farms requires data acquisition in each greenhouse and their transfer to a control unit which is usually located in a control room, separated from the production area.
At present, the data transfer between the greenhouses and the control system is mainly provided by a suitable wired communication system, such as a fieldbus. In such contexts, even though the replacement of the wired system with a fully wireless one can appear very attractive, a fully wireless system can introduce some disadvantages.
A solution based on a hybrid wired/wireless network, where Controller Area Network and ZigBee protocols are used, is presented along with all the related problems that this integration involves. In particular, in order to integrate at the Data Link Layer the wireless section with the wired one, a suitable multiprotocol bridge has been implemented.
Moreover, at the Application Layer, porting of Smart Distributed System services on ZigBee, called ZSDS, allows one to access the network resources independently from the network segment they are connected to.

A SELF-SUPPLIED INERTIAL PIEZOELECTRIC ENERGY HARVESTER WITH POWER-MANAGEMENT IC
ABSTRACT
Harvesting energy from ambient vibrations is a promising technology for fully autonomous wireless sensor nodes, which can give birth to new applications in biomedical, industrial, and environmental monitoring.
There have been independent solutions in increasing the harvesting efficiency either on the mechanical harvester or on its power management circuitry.
Recently, a piezo electric MEMS harvester using AIN was demonstrated to generate enough energy to autonomously power a wireless temperature sensor with a full-bridge rectifier built with off-the-shelf components. Meanwhile, AC-DC converters for piezoelectric harvesters have been designed to enable efficient power extraction, or efficient rectification of low-voltage outputs, and have been tested with commercial meso-scale piezoelectric beams.
However, to realize an efficient stand-alone energy generator platform, it is necessary to integrate these efforts into a single low-volume system. This paper presents a self-supplied energy generator, which includes a MEMS harvester hybridly integrated with its power management circuitry for autonomous charging of an energy reservoir.

A STANDALONE RFID INDOOR POSITIONING SYSTEM USING PASSIVE TAGS
This paper appears in: Industrial Electronics, IEEE Transactions on
ABSTRACT
Indoor positioning systems (IPSs) locate objects in closed structures such as office buildings, hospitals, stores, factories, and warehouses, where Global Positioning System devices generally do not work. Most available systems apply wireless concepts, optical tracking, and/or ultrasound.
This paper presents a standalone IPS using radio frequency identification (RFID) technology. The concept is based on an object carrying an RFID reader module, which reads low-cost passive tags installed next to the object path. A positioning system using a Kalman filter is proposed.
The inputs of the proposed algorithm are the measurements of the backscattered signal power propagated from nearby RFID tags and a tag-path position database. The proposed algorithm first estimates the location of the reader, neglecting tag-reader angle-path loss.
Based on the location estimate, an iterative procedure is implemented, targeting the estimation of the tag-reader angle-path loss, where the latter is iteratively compensated from the received signal strength information measurement. Experimental results are presented, illustrating the high performance of the proposed positioning system.

A TESTBED FOR ANALYZING SECURITY OF SCADA CONTROL SYSTEMS (TASSCS)
ABSTRACT
The critical infrastructures of our society are in the process of being modernized. Most significantly impacted are the industrial control systems through replacement of old electromechanical systems with advanced computing and communication technologies. This modernization has introduced new vulnerabilities to those infrastructures.
Securing critical infrastructures is a challenging research problem, as these control systems were not designed with security in mind. This paper presents a testbed designed to study and simulate the various available techniques for securing and protecting Supervisory Control and Data Acquisition (SCADA) systems against a wide range of cyber attacks.
The testbed is also used to evaluate the detection rate, false alerts and effectiveness of the protection techniques. We present preliminary results on using the testbed to detect a selected set of cyber attacks and the impact of the protection techniques on the operations of the system.

A VIBRATION-BASED ELECTROMAGNETIC ENERGY HARVESTER USING MECHANICAL FREQUENCY UP-CONVERSION METHOD
ABSTRACT
This paper presents a new vibration-based electromagnetic energy harvester using a mechanical frequency up-conversion method for harvesting energy from external low-frequency vibrations within a range of 1-10 Hz.
The structure consists of a magnet placed on a diaphragm, a polystyrene cantilever carrying a pick-up coil, and a mechanical barrier which converts low-frequency vibrations to a higher frequency, hence increasing the efficiency of the system. The tested structure proved to generate 88.6 mV and 544.7 µW rms power output by up-converting 10-Hz external vibration to 394 Hz. The obtained power density is 184 µW/cm3, with a device volume of 2.96 cm3.
An analytical model is developed to analyze the behavior of the energy harvester prototypes with various dimensions. The model predicts the performance parameters of the structures within 5% error range. The effect of scaling down the device dimensions is investigated through the developed model and fabricated prototypes.
It is shown that the power density of the energy harvester is increased as its dimensions are scaled down, proving that the proposed structure is a good candidate to be used in low-power wireless microsystems operating at low-frequency vibrations.

AUTOMATED OFF-LINE RESPIRATORY EVENT DETECTION FOR THE STUDY OF POSTOPERATIVE APNEA IN INFANTS
ABSTRACT
Previously, we presented automated methods for thoraco-abdominal asynchrony estimation and movement artifact detection in respiratory inductance plethysmography (RIP) signals. This paper combines and improves these methods to give a method for the automated, off-line detection of pause, movement artifact, and asynchrony. Simulation studies demonstrated that the new combined method is accurate and robust in the presence of noise. The new procedure was successfully applied to cardiorespiratory signals acquired postoperatively from infants in the recovery room. A comparison of the events detected with the automated method to those visually scored by an expert clinician demonstrated a higher agreement (? = 0.52) than that amongst several human scorers (? = 0.31) in a clinical study . The method provides the following advantages: first, it is fully automated; second, it is more efficient than visual scoring; third, the analysis is repeatable and standardized; fourth, it provides greater agreement with an expert scorer compared to the agreement between trained scorers; fifth, it is amenable to online detection; and lastly, it is applicable to uncalibrated RIP signals. Examples of applications include respiratory monitoring of postsurgical patients and sleep studies.

DESIGN AND IMPLEMENTATION OF A HOME EMBEDDED SURVEILLANCE SYSTEM WITH ULTRA-LOW ALERT POWER
This paper appears in: Consumer Electronics, IEEE Transactions on
ABSTRACT
In this paper we design and implement a home embedded surveillance system with ultra-low alert power. Traditional surveillance systems suffer from an unnecessary waste of power and the shortcomings of memory conditions in the absence of invasion. In this design we use Pyroelectric Infrared sensors (PIR) and pressure sensors as the alert group in windows and doors where an intruder must pass through. These low-power alert sensors wake up the MCU (Micro Controller Unit) which has power management for the ultrasonic sensors and PIR sensors indoors. This state transition method saves a large number of sensors required for the alert power. We also use the Majority Voting Mechanism (MVM) to manage the sensor groups to enhance the probability of multiple sensors sensing. After the MCU sends the sensor signals to the embedded system, the program starts the Web camera. Our sensing experiment shows that we reduce the system's power consumption.

With respect to the advantages and disadvantages of all the sensors, according to the actual work condition, in this system the sensors information is rationally selected as measurements, and the centralized Kalman filter algorithm is adopted to estimate and correct the errors of the system. Thus it can realize the high-accuracy, continuous and reliable navigation of the system.

DETECTION OF COGNITIVE INJURED BODY REGION USINGMULTIPLE TRIAXIAL ACCELEROMETERS FOR ELDERLY FALLING
ABSTRACT
This paper aimed to use several triaxial acceleration sensor devices for joint sensing of injured body parts, when an accidental fall occurs. The model transmitted the information fed by the sensors distributed over various body parts to the computer through wireless transmission devices for further analysis and judgment, and employed cognitive adjustment method to adjust the acceleration range of various body parts in different movements. The model can determine the possible occurrence of fall accidents, when the acceleration significantly exceeds the usual acceleration range. In addition, after a fall accident occurs, the impact acceleration and normal (habitual) acceleration can be compared to determine the level of injury. This study also implemented a sensing system for analysis. The area of the body parts that may sustain greater impact force are marked red in this system, so that more information can be provided for medical personnel for more accurate judgment.

DEVELOPMENT OF A DISTRIBUTED DATA COLLECTION SYSTEM BASED ON EMBEDDED ETHERNET
ABSTRACT
We describe a low cost distributed data collection system based on embedded Ethernet. Embedded Ethernet is nothing but a microcontroller which is able to communicate with the network. Low cost microcontrollers have memory limitations, and therefore, have limited connectivity options. Enabling a microcontroller to communicate to a data communication network would allow greater flexibility and enhance their usage in several applications that require distributed data collection, monitoring or controlling such applications.

ENHANCED VOICE ACTIVITY DETECTION USING ACOUSTIC EVENT DETECTION AND CLASSIFICATION
This paper appears in: Consumer Electronics, IEEE Transactions on
ABSTRACT
We examine user-friendly voice interface that requires the hands-free speech acquisition in the continuously listening environment. The traditional voice activity detection (VAD) algorithms cannot successfully identify potential acoustic event sounds from speech. This makes the speech recognition system frequently or incorrectly activated. In this paper, we propose a novel voice activity detection technique that consists of two major modules: 1) classification and 2) detection module. In the classification module, we label the successive audio segments based on the training models. Then, in the detection module, we remove the acoustic event sounds and make decision of the explicit utterance boundary from the input audio stream. As a result, the proposed technique enables the efficient operation of speech recognition in the continuously listening environment without any touch and/or key input. Experiments in a real-world environment and performance comparison with state-of-the-art techniques are conducted to demonstrate the effectiveness of the proposed technique.

ABSTRACT
The present paper addresses the topic of fault location in power networks with cable lines. In the era of smart-grid the demand of intelligent measurement systems capable of providing quickly and with high accuracy the right location of faults in power networks is growing fast. Many proposals can be found in literature relevant to different approaches. Some commercial instrumentation is also available on the market for this purpose. Protection relays implementing this feature can either be found. This paper presents the experimental results of a measurement campaign carried out in the MV power network in the city of Milan (Italy). For this purpose the local Utility (A2A SpA) is using a commercial distributed measurement system (the ALTEA FLS) for locating both faults and also fast transients due to customers' loads operation. Preliminary experimental results have shown good performance. They have been better analyzed in order to investigate over the reliability and the accuracy of such measurement system.

FEATURE SELECTION FOR ACCELEROMETER-BASED POSTUREANALYSIS IN PARKINSON’S DISEASE
This paper appears in: Information Technology in Biomedicine, IEEE Transactions on
ABSTRACT
Posture analysis in quiet standing is a key component of the clinical evaluation of Parkinson's disease (PD), postural instability being one of PD's major symptoms. The aim of this study was to assess the feasibility of using accelerometers to characterize the postural behavior of early mild PD subjects. Twenty PD and 20 control subjects, wearing an accelerometer on the lower back, were tested in five conditions characterized by sensory and attentional perturbation. A total of 175 measures were computed from the signals to quantify tremor, acceleration, and displacement of body sway. Feature selection was implemented to identify the subsets of measures that better characterize the distinctive behavior of PD and control subjects. It was based on different classifiers and on a nested cross validation, to maximize robustness of selection with respect to changes in the training set. Several subsets of three features achieved misclassification rates as low as 5%. Many of them included a tremor-related measure, a postural measure in the frequency domain, and a postural displacement measure. Results suggest that quantitative posture analysis using a single accelerometer and a simple test protocol may provide useful information to characterize early PD subjects. This protocol is potentially usable to monitor the disease's progression

ABSTRACT
Recently the Electrical supply companies are trying to adopt the electronic measurement of energy consumption data because of reduced manufacturing cost, improved measurement accuracy, increased timely information, miniature size and many other benefits that go well beyond the traditional rotor-plate energy meter type. In this paper with the help of an energy chip, an improved energy metering solution is developed, where automating the progression of measurement through digital wireless communication technique is adopted to get the above benefits along with smooth control. The developed energy meter calculates the total average active power mainly for residential consumers. The hardware circuit accepts single phase voltage and currents as its inputs and provides the output in the form of logic data proportional to the average real power. This data is fed to a remote computer server through the wireless ZigBee network that represents the concept of distant wireless metering, practically involving no manpower. This paper also presents a software solution developed for total electrical energy billing and data management system.

MODEL-BASED OPTIMAL EFFICIENCY CONTROL OF INDUC-TION GENERATORS FOR WIND POWER SYSTEMS
ABSTRACT
In this paper, a novel control algorithm for optimal operating efficiency of induction generators for wind power generation is presented. The proposed method is based on the flux level reduction, where the flux level is computed from the machine model for the optimum d-axis current of the generator. For the vector-controlled induction generator, the d-axis current controls the excitation level in order to minimize the generator loss while the q-axis current controls the generator torque, by which the speed of the induction generator is controlled according to the variation of the wind speed in order to produce the maximum output power. An experimental setup has been implemented in laboratory to validate the theoretical development. The experimental results show that the loss minimization process is more effective at low wind speed and that the percent of power saving can approach to 25%. Experimental results are shown to verify the validity of the proposed scheme

ABSTRACT
On the basis of a previous one-axis accelerometer motion compensation system for automotive SAR, an updated scheme is presented in this paper, which contains a one-axis gyroscope and two-axis accelerometer. The requirement for extra Degrees of Freedom (DoF) leads to a new motion signal model. The complete procedure of calculating motion deviation in image display plane (IDP) from the raw roll angle rate and accelerations measured in body frame has been presented. The requirement for the Inertial Measurement Unit (IMU) has been analyzed quantitatively. According to the out-field measurements, the improved motion compensation system can cope with worse road conditions.

ON-LINE RECOGNITION OF DRIVING ROAD CONDITION USING SUPPORT VECTOR MACHINE
ABSTRACT
A person operating a mobile robot in a remote environment receives a realistic visual feedback about the condition of the road on where the mobile robot is moving. A categorization of the road condition is necessary to evaluate the condition for safe and comfortable driving. For this purpose, the mobile robot should be capable of recognizing and classifying the condition of the road surfaces. In a previous research, author proposed a method to recognize the type of the road surfaces on the basis of the friction between the mobile robot and the road surfaces. The friction is estimated by a reaction torque observer, and a Support Vector Machine (SVM) is used to classify the surfaces. In this paper, SVM is calculated on-line, and multi-class classification is realized. Moreover, the operator is given feedback of haptic information by using mobile-hapto system As a result, the operator is given visual and force feedback about road condition. By experiments, the validity of the proposed method is confirmed.

OPTIMIZED WIND ENERGY HARVE STING SYSTEM USING RESISTANCE EMULATOR AND ACTIVE RECTIFIER FOR WIRELESS SENSOR NODES
ABSTRACT
This paper presents an optimized wind energy harvesting (WEH) system that uses a specially designed ultra-low-power-management circuit for sustaining the operation of a wireless sensor node. The proposed power management circuit has two distinct features: 1) an active rectifier using MOSFETs for rectifying the low amplitude ac voltage generated by the wind turbine generator under low wind speed condition efficiently and 2) a dc-dc boost converter with resistor emulation algorithm to perform maximum power point tracking (MPPT) under varying wind-speed conditions. As compared to the conventional diode-bridge rectifier, it is shown that the efficiency of the active rectifier with a low input voltage of 1.2 V has been increased from 40% to 70% due to the significant reduction in the ON-state voltage drop (from 0.6 to 0.15 V) across each pair of MOSFETs used. The proposed robust low-power microcontroller-based resistance emulator is implemented with closed-loop resistance feedback control to ensure close impedance matching between the source and the load, resulting in an efficient power conversion. From the experimental test results obtained, an average electrical power of 7.86 mW is harvested by the optimized WEH system at an average wind speed of 3.62 m/s, which is almost four times higher than the conventional energy harvesting method without using the MPPT.

PERFORMANCE OF POWER LINE COMMUNICATION SYSTEMS WITH NOISE REDUCTION SCHEME FOR SMART GRID APPLICATIONS
This paper appears in: Consumer Electronics, IEEE Transactions on
In this paper, we propose clipping scheme and equalizer as methods to reduce the effects of impulsive noise and channel attenuation in power line communication (PLC) system. Clipping is cutting off the amplitude of the received signal over threshold level without its phase change in order to reduce noise effects. The equalizer compensates for effects of PLC channel. The performance is evaluated in terms of bit error rate (BER). From simulation results, it is confirmed that the proposed clipping scheme has slightly better performance than conventional PLC system. The results of the paper can be applied to PLC systems for smart grid.

PHYSICAL MOVEMENT MONITORING USING BODY SENSORNETWORKS: A PHONOLOGICAL APPROACH TO CONSTRUCT SPATIAL DECISION TREES
This paper appears in: Industrial Informatics, IEEE Transactions on
ABSTRACT
Monitoring human activities using wearable sensor nodes has the potential to enable many useful applications for everyday situations. Limited computation, battery lifetime and communication bandwidth make efficient use of these platforms crucial. In this paper, we introduce a novel classification model that identifies physical movements from body-worn inertial sensors while taking collaborative nature and limited resources of the system into consideration. Our action recognition model uses a decision tree structure to minimize the number of nodes involved in classification of each action. The decision tree is constructed based on the quality of action recognition in individual nodes. A clustering technique is employed to group similar actions and measure quality of per-node identifications. We pose an optimization problem for finding a minimal set of sensor nodes contributing to the action recognition. We then prove that this problem is NP-hard and provide fast greedy algorithms to approximate the solution. Finally, we demonstrate the effectiveness of our distributed algorithm on data collected from five healthy subjects. In particular, our system achieves a 72.4% reduction in the number of active nodes while maintaining 93.3% classification accuracy.

Simulation of earthquakes and tsunami through GSM network
ABSTRACT
Every year thousands of people die because of earthquake occurs in a dangerous place or during a defenseless sleep. Here's a GSM-based seismic alert system that could warn before an earthquake strikes. Earthquakes strike without warning. The resulting damage can be minimized and lives can be saved if people living in the earthquake-prone area are already prepared to survive the strike. This requires a warning before strong ground motion from the earthquake arrival. Such a warning system is possible because of energy wave released at the epicenter of the earth quake travels slower than light. The warning signal from the earthquake epicenter can be transmitted to different places using satellite communication network, fiber-optics network, pager service, Cell phone services or a combination of these. The satellite-based network is ideal when an alert system has to cover a large country like India. For earthquake-prone states like Gujarat, a seismic alert system using the global system for mobile communication network spread throughout the state is proposed here. This system does not try to find the epicenter or fault line caused by the earthquake. It simply monitors the earth vibrations and generates alert signal when the level of earth vibrations crosses a threshold.

RF Fingerprinting Physical Objects for Anticounterfeiting Applications
ABSTRACT
Rendering typical RF identification (RFID) tags physically unique and hard to near-exactly replicate by complementing them with unique RF certificates of authenticity (RF-CoAs) can prove a valuable tool against counterfeiting. This paper introduces a new robust RFID system with enhanced hardware-enabled authentication and anticounterfeiting capabilities that relies on the near-field RF effects between a 5 × 5 antenna array and the uniquely modified substrate of the RF-CoAs. A microcontroller-enabled, low-power, and low-cost reader is used to accurately extract the near-field response (“RF fingerprint”) of the certificates meant to complement typical RFID tags in the 5-6-GHz frequency range. The RF characterization of all the reader's components, with an emphasis on the accuracy provided, has been performed. The state diagram of the fast and accurate reader operation is outlined. Rigorous performance and security test results are presented and verify the unique features of this technology.

TORSIONAL-VIBRATION ASSESSMENT AND GEAR-FAULTDIAGNOSIS IN RAILWAY TRACTION SYSTEM
ABSTRACT
The diagnosis of mechanical faults in railway traction systems (RTSs) has a significant importance on both safety and reliability, which can avoid train crashes. This paper deals with torsional-vibration assessment and gear-fault diagnosis in the mechanical transmission of a high-speed RTS by a fully noninvasive technique. Previous studies on a simple gearbox-based electromechanical system have shown that the influence of gearbox torsional vibrations on the torque and on the stator-current signatures are obvious. The aim of this paper is to demonstrate that the traction motor can be considered as a torque sensor through its electromagnetic-torque estimation for torsional-vibration monitoring without any extra mechanical sensor. The effects of both tooth-damage and surface-wear faults at the output wheel on the stator current and on the estimated electromagnetic torque have been investigated. The results of the estimation are compared with the measured mechanical torque and validated through a reduced-scale RTS in both stationary and nonstationary conditions.

In this system, with the help of the RFID tags in the ambulances and wireless sensor nodes on the roads, the dispatch control center in the hospital can collect the real-time traffic conditions where wireless sensor nodes locates. The report messages are sent to the control center by the multi-hop method. Based on the information coming from sensor nodes, the control center forecasts the optical path to provide the fastest route for the ambulances. In this decision process, the control center will ignore some information from the nodes, which have higher traffic jam than the average. Experimental results show that our system can provide the best route to the ambulances. And it also has the more potential applications in wide areas.

VEHICLE INFRASTRUCTURE INTEGRATION SYSTEM USING VISIONSENSORS TO PREVENT ACCIDENTS IN TRAFFIC FLOW
ABSTRACT
This study describes the development of a vision sensor for detecting shock waves which is one of the main factors of accidents in highway traffic flow. The major contributions of this research are development of vehicle tracking and detection of shock wave in saturated traffic. Moreover, realisation of a vehicle infrastructure integration (VII) system for providing arrival information of such propagation to drivers is proposed. The experiment on the analysis of the propagation with the developed image sensor has shown that an error might occur in the arrival time information of the propagation provided to the driver. Therefore a prediction technique at the arrival time of the propagation is integrated in the authors' system. By using this prediction technique and taking the error tolerance of drivers into account, the experimental results show that prediction success rates are improved by about 5%.

LOCON: A LOCATION BASED SERVICES PLATFORM TO IMPROVE AIRPORT SAFETY
ABSTRACT
Location and context awareness services have generated a lot of interest in the recent years, becoming a key feature to many applications of mobile devices. The rapid development in wireless communications and in satellite navigation systems also contributed to the popularity of location based services. The location technologies when properly combined can provide valuable event driven services to notify users about ongoing occurrences, creating important advances in surveillance activities. This is particularly relevant for operational environments where surveillance of surface movement's through electronic means represents a major challenge. Although advantages in location based services have opened up new perspectives at validating safety and security requirements in environments such as airports, harbours, or industrial plants, there are, however different ways to look at these services to provide location awareness. This paper presents a contribution developed in an European research project called LocON that implements a generic platform to provide a set of location based services using different wireless location technologies. The location awareness provided by the LoCON platform relies on multiple location-based technologies which cooperate at providing the data to a middleware layer. Based on a data fusion process the positioning data are passed to the application layer enabling operational decision makers to monitor and track events according to business logic. LocON is being tested at Faro airport in Portugal to validate how well it can improve airport safety and security procedures.

HARDWARE–SOFTWARE CODE SIGN OF AUTOMATIC SPEECH RECOGNITION SYSTEM FOR EMBEDDED REAL-TIME APPLICATIONS
ABSTRACT
We present a hardware-software coprocessing speech recognizer for real-time embedded applications. The system consists of a standard microprocessor and a hardware accelerator for Gaussian mixture model (GMM) emission probability calculation implemented on a field-programmable gate array. The GMM accelerator is optimized for timing performance by exploiting data parallelism. In order to avoid large memory requirement, the accelerator adopts a double buffering scheme for accessing the acoustic parameters with no assumption made on the access pattern of these parameters. Experiments on widely used benchmark data show that the real-time factor of the proposed system is 0.62, which is about three times faster than the pure software-based baseline system, while the word accuracy rate is preserved at 93.33%. As a part of the recognizer, a new adaptive beam-pruning algorithm is also proposed and implemented, which further reduces the average real-time factor to 0.54 with the word accuracy rate of 93.16%. The proposed speech recognizer is suitable for integration in various types of voice (speech)-controlled applications.

DISCUSSIONS ON ACCESSIBILITY IN INDUSTRIAL AUTOMATION SYSTEMS
ABSTRACT
Importance of industrial automation systems [1], also known as technical devices, has been a growing area during the past decades. Web applications from one side and industrial automation systems from the other side have become a standard part of people's daily life and more user groups have to deal with them. Hence they must be accessible to all users. Unfortunately, often by the development of such systems, certain user groups are being neglected. Therefore, a systematic concept is required to support the development of industrial automation systems and Web applications. In this paper, we will present the concept, which is proposed in the context of a research project funded by Deutsche Forschungsgemeinschaft (DFG)a. We will discuss the suited methods to effectively assess accessibility requirements.

A SYSTEM FOR THE DYNAMIC CONTROL AND THERMAL CHARACTERIZATION OF ULTRA LOW POWER GAS SENSORS
ABSTRACT
This paper describes a system for the simultaneous dynamic control and thermal characterization of the heating and cooling phases of an ultralow-power (ULP) micromachined sensor, featuring thermal characteristics that are quite similar to those of innovative ULP semiconducting metal-oxide gas sensors. A pulsewidth-modulated (PWM) excitation system has been realized using a microcontroller featuring an ARM7 core to characterize the thermal behavior of a device formed by a Pt microheater and a Pt temperature sensor, over an insulating membrane. Three operating modes, i.e., constant target heater resistance, constant heating power, and cooling phase monitoring, were implemented. Objectives of the research were to analyze the relation between the time period and duty cycle of the PWM signal and the operating temperature of such ULP micromachined systems, to observe the thermal time constants of the device during the heating and cooling phases, and to measure the total thermal conductance. Experiments indicated that an approximately constant heater temperature in the constant target heater resistance regime (i.e., after the initial thermal transient due to the heating algorithm) can only be obtained if the time period of the heating signal is smaller than 50 µs, i.e., much faster than the time constant of the device. Constant power experiments show quantitatively a unique time constant t for both the heater and the temperature sensor (T-sensor) in the heating phase (with a known applied power) and the cooling phase (with zero power). This time constant decreases during heating in a range of 2.3-2 ms as a function of an increasing temperature rise ?T between the ambient and the operating temperature. Moreover, we observed that, in the chosen operating temperature range, the thermal conductance is a linear function of ?T. Finally, repeatability of experimental results was assessed by guaranteeing that the standard deviation of the controlled temperature was within ±5.5°C in worst-case conditions.

IMPLEMENTATION OF IN-VEHICLE MULTI-SENSOR INFORMATION FUSION GATEWAY FOR COOPERATIVE DRIVING
Active safety is an important feature of a modern vehicle to provide precaution warning or compensatory control before the pre-crash stage of vehicle safety. All vehicle signals and information are acquired by several in-vehicle sensors on ECUs or surrounding vehicles, and integrated in vehicle gateway through in-vehicle or vehicle-to-vehicle communications. The information exchanged among the host and surrounding vehicles provides comprehensive vehicle and driving status of each vehicle, so the driver can drive more safely with the cooperative driving mechanism. The demonstration system consists of a vehicle gateway, which is based on a heterogeneous multi-core processor, consisting of one ARM core for I/O control and system management and two DSP cores for intensive computation of information fusion. After reaching within the communication limit, the vehicles set up time synchronization and then exchange vehicle information. The acquired sensor data and received vehicle information are time aligned and fed into PAC DSPs for information fusion, which consists of four phases, signal processing, location mapping, trajectory prediction and risk assessment. The risk assessment evaluates the probability of car crash and broadcast the warning message to its surrounding vehicles, if the risk level is raised beyond a threshold. The cooperative driving is fulfilled by sharing the vehicle information and emergency warning through wireless communication, so a driver can be aware of the dangerous situation and also be suggested an adequate response earlier.

THE RESEARCH ON OPTIMAL PARKING SPACE CHOICE MODEL IN PARKING LOTS
ABSTRACT
In order to deal with the parking guidance issue of the parking guidance and information system in the parking lots, the behavior of choosing parking space was analyzed to build the optimal parking space choice model in the parking lots. Based on the specific situation of the parking lots, the habits and preferences of the drivers when parking their cars were all taken into consideration in this model. After summarizing the key factors which may influence drivers' parking space choice, a multiple attribute decision parking model is proposed to help PGIS in the parking lots choose the optimal parking space for drivers. A case is presented to verify the proposed model. The results show that the model can choose the optimal parking space and provide effective guidance for drivers. It can also take the drivers less time to find the parking space and it will take great help to the intelligent management for the parking guidance and information system, too.

MEASURING NEUROMUSCULAR CONTROL DYNAMICS DURING CAR FOLLOWING WITH CONTINUOUS HAPTIC FEEDBACK
ABSTRACT
In previous research, a driver support system that uses continuous haptic feedback on the gas pedal to inform drivers of the separation to the lead vehicle was developed. Although haptic feedback has been previously shown to be beneficial, the influence of the underlying biomechanical properties of the driver on the effectiveness of haptic feedback is largely unknown. The goal of this paper is to experimentally determine the biomechanical properties of the ankle–foot complex (i.e., the admittance) while performing a car-following task, thereby separating driver responses to visual feedback from those to designed haptic feedback. An experiment was conducted in a simplified fixed-base driving simulator, where ten participants were instructed to follow a lead vehicle, with and without the support of haptic feedback. During the experiment, the lead vehicle velocity was perturbed, and small stochastic torque perturbations were applied to the pedal. Both perturbations were separated in the frequency domain to allow the simultaneous estimation of frequency response functions of both the car-following control behavior and the biomechanical admittance. For comparison to previous experiments, the admittance was also estimated during three classical motion control tasks (resist forces, relax, and give way to forces). The main experimental hypotheses were that, first, the haptic feedback would encourage drivers to adopt a “give way to force task,” resulting in larger admittance compared with other tasks and, second, drivers needed less control effort to realize the same car-following performance. Time- and frequency-domain analyses provided evidence for both hypotheses. The developed methodology allows quantification of the range of admittances that a limb can adopt during vehicle control or while performing a variety of motion control tasks. It thereby allows detailed computational driver modeling and provides valuable information on how to design an- - d evaluate continuous haptic feedback systems.

THE IMPLEMENTATION OF THE INTELLIGENT TRANSPORT SYSTEM FOR THE REAL-TIME ROADSIDE ENVIRONMENT INFORMATION TRANSFER
ABSTRACT
The paper proposed a novel system “RTCS (Real-Time Control System for road environment)” to prevent accidents of drivers. This paper deployed sensors on roads and used these sensors to collect information to coordinators. How to use sensors to prevent accidents in vehicular environment is an interesting issue. Vehicles are equipped with OBU (On-Board Unit) and use the OBU to query information if the coordinator or RSU (Road-Side Unit) is located in its communication range. This system also distributed events into different priority due to the different damages. For your example, RSU collects and analyzes the roadside information for the driver's safety and which provides to an OBU and a management system according to the service priority. In the higher rank terminal, the developed IP-based set-top box application provides information such as the traffic information, road environmental information, environmental sensor station error, and etc. The system has a high potential to improve traffic in two ways. First, it collects local environmental data and passes it to a central facility to further process it and pass it to vehicles. Second, it takes care that urgent local information is passed directly and thus quickly to local vehicles which increases traffic safety. The paper presents architecture to connect a USN (Ubiquitous Sensor Network) with the ITS (Intelligent Transport System) consisting of connected OBU and RSU. The goal of the system is to provide the ITS with local environmental data gathered by the USN nodes.

A pragmatic approach to aid visually impaired people in reading, visualizing and understanding textual contents with an automatic electronic pen
ABSTRACT
Blindness is an obstacle that is not even comprehendible for the non-blind. Many day-to-day activities may become challenging, complicated and may require much more labor for those with eye-sight problems or blindness. One of the major problems they face is understanding visual or text information which are not in the Braille form. Not every written or printed document that a blind person would like to read is available in Braille. A blind cannot read any of the handwritten documents. They feel it very difficult, while someone has to read it for them. This is the fundamental issue that we deal with, and try to solve, with a new piece of technology, which is essentially an automated text-to-audio converting pen. According to this keynote concept, any piece of text that a person would like to read/understand is converted to an audio signal. This audio signal is transmitted to the person's ears through wireless technology such as ZigBee. Since this technology is in the form of a pen, it is very convenient to use and is also portable. This instrument is radical and can definitely be a empowering force in a blind person's life, and can be helpful in relieving them of their frustration of not being able to read whatever they want, thus making their life easier.

SMART CARD WITH IRIS RECOGNITION FOR HIGH SECURITY ACCESS ENVIRONMENT
ABSTRACT
Smart cards are increasingly being used as a form of identification and authentication. One inherent problem with smart cards, however, is the possibility of loss or theft. Current options for securing smart cards against unauthorized use are primarily restricted to passwords. Passwords are easy enough for others to steal so that they do not offer sufficient protection. This has promoted interest in biometric identification methods, including iris recognition. The iris is, due to its unique biological properties, exceptionally suited for identification. It is protected from the environment, stable over time, unique in shape and contains a high amount of discriminating information. This paper proposes a method to integrate iris recognition with the smart card to develop a high security access environment. An iris recognition system and smart card programming circuit with its software have been designed. Template on card (TOC) category has been employed. Hence, the extracted iris features stored in smart card are compared against the data acquired from a camera or database for authentication. The proposed algorithm has superior performance in terms of security, accuracy and consistency compared with other published technology.

COMPUTING TECHNOLOGY USED IN RETRIEVAL OF PATIENT’S RECORD
ABSTRACT
The majority of healthcare workers in hospitals continue to record, access and update important patient information using paper charts. Disparate patient data (clinical information, laboratory results and medical imagery) is entered by different caregivers and stored at different locations around the hospital. This is a cumbersome, time consuming process that can result in critical medical errors such as documents being mislaid or prescriptions being misinterpreted due to illegible handwriting. Hospitals everywhere are moving to integrate health data sources using Electronic Health Record (EHR) systems as well as taking advantage of the flexibility and speed of wireless computing to improve the quality and reduce the cost of healthcare. We are developing a mobile application that allows doctors to efficiently access accurate real-time patient information at the point-of-care. The system can assist caregivers in automatically searching through very large repositories of previous patient cases as increasingly large hospital databases are making manual searches of such information unfeasible. The system performs computational prognosis by providing decision support for pre-screening of medical diagnosis. A presenting patient's symptoms can be input to a portable device and the application can quickly retrieve the most similar profiles with known diagnoses from large databases which can be used to compare treatments, diagnosis, test results and other information.

THE SOLUTION OF HYBRID ELECTRIC VEHICLE INFORMATION SYSTEM BY MODBUS PROTOCOL
ABSTRACT
This paper introduces the hybrid electric vehicle information system, which is realized by modbus protocol. Using a remote terminal control unit (RTU) with EVEW touch-screen, the system achieves the communication between electronic control units (ECU) and the RTU by means of the modbus protocol at the baud rate 38400kb/s, and it finishes the task of human-machine exchange. Hybrid electric vehicle control unit uses dual-core processors: the host processor and the coprocessor XGATE. XGATE can reduce the load on the host processor, which makes the host processor timely response to a number of hybrid control tasks, and it improves the requirements of real-time in hybrid control system. In addition, because modbus protocol has opening characteristics, most of serial communication controllers support the protocol. Therefore, the system can be applied in the serial communication with modbus protocol.

A TEST BED FOR ANALYZING SECURITY OF SCADA CONTROL SYSTEMS (TASSCS)
ABSTRACT
The critical infrastructures of our society are in the process of being modernized. Most significantly impacted are the industrial control systems through replacement of old electromechanical systems with advanced computing and communication technologies. This modernization has introduced new vulnerabilities to those infrastructures. Securing critical infrastructures is a challenging research problem, as these control systems were not designed with security in mind. This paper presents a testbed designed to study and simulate the various available techniques for securing and protecting Supervisory Control and Data Acquisition (SCADA) systems against a wide range of cyber attacks. The testbed is also used to evaluate the detection rate, false alerts and effectiveness of the protection techniques. We present preliminary results on using the testbed to detect a selected set of cyber attacks and the impact of the protection techniques on the operations of the system.

SUPPORT VECTOR MACHINE BASED DATA CLASSIFICATION FOR DETECTION OF ELECTRICITY THEFT
ABSTRACT
Most utility companies in developing countries are subjected to major financial losses because of non-technical losses (NTL). It is very difficult to detect and control potential causes of NTL in developing countries due to the poor infrastructure. Electricity theft and billing irregularities form the main portion of NTL. These losses affect quality of supply, electrical load on the generating station and tariffs imposed on electricity consumed by genuine customers. In light of these issues, this paper discusses the problems underlying detection of electricity theft, previously implemented ways for reducing theft. In addition, it presents the approximate energy consumption patterns of several customers involving theft. Energy consumption patterns of customers are compared with and without the presence of theft. A dataset of customer energy consumption pattern is developed based on the historical data. Then, support vector machines (SVMs) are trained with the data collected from smart meters, that represents all possible forms of theft and are tested on several customers. This data is classified based on rules and the suspicious energy consumption profiles are grouped. The classification results of electricity consumption data are also presented.

Energy diversification is very important to the sustainable economy growth. In this paper we develop an endogenous growth model and analyze some major relationship between the energy diversification and sustainable economy growth. The dynamic optimization results of the model show that the technology progress will make great contributions to the energy diversification and the specialized energy R&D plays an important role in the energy diversification process, which can accelerates energy supply source expansion. Propelled by the specialized energy R&D, energy diversification will redistribute the labor force among different sectors, offset the adverse effects of diminishing marginal return of factors, and help economy step into sustainable growth e entually.

DEVELOPING AND INSTALLING SUBSTATIONS FOR OIL AND GAS FACILITIES IN VERY COLD AND REMOTE LOCATIONS
ABSTRACT
Oil and gas companies are venturing into colder, more remote locations in their search for attainable oil and gas reserves. In many instances, extracting these “harder to reach” reserves requires power intensive unconventional methods. Heaters, drill rigs, compressors, pumps, and other exploration and production equipment required for the exploration and production operations can amount to hundreds of megawatts. To supply these large loads, oil and gas companies are using electric power at higher voltage levels and installing their own transmission and distribution substations and, in some cases, their own transmission and distribution network. Historically, substation designs were based on previous engineering experience and knowledge. Given the challenges associated with frontier extreme weather locations, defaulting to traditional designs may be a flawed approach. This paper discusses different aspects to consider in the development and installation of remote high-voltage substations in very cold conditions, with emphasis on a few key criteria: personnel safety and environmental issues, reliability and availability, low maintenance, remote monitoring and control, equipment and material suitable for cold environment, and cost effectiveness. Other considerations such as unique end-user requirements, qualified labor resources, logistics challenges, and cost optimization will also be discussed. A methodology incorporating the aforementioned factors will be offered for selecting a substation solution for a large oil and gas facility in a cold and remote location.

CONTROL LAYER FOR MULTI-VENDOR INDUSTRIAL ROBOT INTERACTION PROVIDING INTEGRATION OF SUPERVISORY PROCESS CONTROL AND MULTIFUNCTIONAL CONTROL UNITS
ABSTRACT
Based on recent industrial needs for a flexible integration of supervisory control systems and novel intuitive manual control units a new control layer is introduced. The control layer affords adaptive behaviour in terms of process and motion planning as well as flexible manual control of arbitrary robot controllers. It is located between the industrial robot controller and the control units. For the purpose of a flexible manufacturer-independent access to the robot controller we define an object-oriented programming interface. The set of robot commands is manufacturer-independent and includes all basic robot functions regarding motion and program control. An inherent capability of the control layer is the transformation of neutral object-oriented robot commands to manufacturer-specific robot languages. With an emphasis on the development of a flexible control layer, we aim for a media-independent communication solution. In order to cover a broad range of robotic applications, different communication standards of industrial automation are implemented. Finally, two applications, a smartphone robot control and a distributed robot control system, are presented and discussed.

EVALUATION OF TELE-ROBOTIC INTERFACE COMPONENTS FOR TEACHING ROBOT OPERATION
ABSTRACT
Remote-learning has been an increasingly growing field in the last two decades. The Internet development, as well as the increase in PC's capabilities and bandwidth capacity, has made remote-learning through the internet a convenient learning preference, leading to a variety of new interfaces and methods. In this work, we consider a remote-learning interface, developed in a Computer-Integrated-Manufacturing (CIM) Laboratory, and evaluate the contribution of different interface components to the overall performance and learning ability of end users. The evaluated components are the control method of the robotic arm and the use of a three-dimensional simulation tool before and during the execution of a robotic-task. An experiment is designed and executed, comparing alternative interface designs for remote-learning of robotic-operation. A Teleoperation task was given to 120 engineering students through five semesters. The number of steps required for completing the task, the number of errors during the execution and the improvement rate during the execution were measured and analyzed. The results provide guidelines for a better design of an interface for remote-learning of robotic-operation. The main contribution of this paper is in the introduction of a new teaching tool for laboratories and the supplied guidelines for an efficient design of such tools.

A ZigBee-based telecardiology system for remote healthcare service delivery
ABSTRACT
Patients with heart disease suffer much to have diagnostic ECG sessions especially in rural areas and areas with high population. This is mainly due to the remoteness of distance between patients and the medical units, as well as traffic congestion. Doctors also need a fast and reliable way to be able to check on their patients and provide a diagnosis irrespective of where they are. In this paper we describe the design and implementation of a telecardiology system using ZigBee. Our proposed system will provide doctors with the ability to monitor, and diagnose their patients remotely over the Internet. The system is capable of receiving a serial stream of data and extracting relevant packets from the measurements of the patient's vital signs. The implemented software allows patients to easily connect with their doctors and to send their data via Internet. The ECG signal is monitored in a real-time mode with the ability of keeping records through SCP-ECG (Standard Communication Protocol) standard.

ISOLATED WIND–HYDRO HYBRID SYSTEM USING CAGE GENERATORS AND BATTERY STORAGE
ABSTRACT
This paper deals with a new isolated wind-hydro hybrid generation system employing one squirrel-cage induction generator (SCIG) driven by a variable-speed wind turbine and another SCIG driven by a constant-power hydro turbine feeding three-phase four-wire local loads.
The proposed system utilizes two back-to-back-connected pulsewidth modulationcontrolled insulated-gate-bipolar-transistor-based voltage-source converters (VSCs) with a battery energy storage system at their dc link.
The main objectives of the control algorithm for the VSCs are to achieve maximum power tracking (MPT) through rotor speed control of a wind-turbine-driven SCIG under varying wind speeds and control of the magnitude and the frequency of the load voltage.
The proposed wind-hydro hybrid system has a capability of bidirectional active- and reactive-power flow, by which it controls the magnitude and the frequency of the load voltage.
The proposed electromechanical system using SCIGs, an MPT controller, and a voltage and frequency controller are modeled and simulated in MATLAB using Simulink and Sim Power System set toolboxes, and different aspects of the proposed system are studied for various types of linear, nonlinear, and dynamic loads, and under varying wind-speed conditions.
The performance of the proposed system is presented to demonstrate its capability of MPT, voltage and frequency control (VFC), harmonic elimination, and load balancing.

TECHNO-ECONOMIC ANALYSIS OF SVC-HVDC TRANSMISSION SYSTEM FOR OFFSHORE WIND
ABSTRACT
One of the trends concerning offshore wind farms is to increase the distance from the wind farm to the shore, and has to be transported over very long distances to make a connection with the main supply grid. But placing wind farms offshore rises a lot o challenges related to construction, installation and nevertheless with the energy transmission.
VSC HVDC is a rather new technology with promising characteristics for offshore wind transmission. And the techno-economic value analysis for VSC HVDC is necessary as all projects require a maximal effort in order to make the offshore wind farm viable. The possible structures for offshore wind farm and some feasible turbine topologies for offshore wind were introduced in the paper.
Based on the grid code requirements, a techno-economic analysis for VSC HVDC with SCIG was proposed. This HVDC system is compared to the main variable-speed topologies (DFIG and DDPMSG) in combination with HVAC and a typical wind farm is put upfront to investigate. Result show that the SVC HVDC transmission system with SCIC could get a cost-efficient.

GRID INTERCONNECTION OF RENEWABLE ENERGY SOURCES AT THE DISTRIBUTION LEVEL WITH POWER-QUALITY IMPROVEMENT FEATURES
ABSTRACT
Renewable energy resources (RES) are being increasingly connected in distribution systems utilizing power electronic converters. This paper presents a novel control strategy for achieving maximum benefits from these grid-interfacing inverters when installed in 3-phase 4-wire distribution systems.
The inverter is controlled to perform as a multi-function device by incorporating active power filter functionality. The inverter can thus be utilized as: 1) power converter to inject power generated from RES to the grid, and 2) shunt APF to compensate current unbalance, load current harmonics, load reactive power demand and load neutral current.
All of these functions may be accomplished either individually or simultaneously. With such a control, the combination of grid-interfacing inverter and the 3-phase 4-wire linear/non-linear unbalanced load at point of common coupling appears as balanced linear load to the grid.
This new control concept is demonstrated with extensive MATLAB/Simulink simulation studies and validated through digital signal processor-based laboratory experimental results.

A NEW APPROACH TO MULTIFUNCTIONAL DYNAMIC VOLTAGE RESTORER IMPLEMENTATION FOR EMERGENCY CONTROL IN DISTRIBUTION SYSTEMS
ABSTRACT
The dynamic voltage restorer (DVR) is one of the modern devices used in distribution systems to protect consumers against sudden changes in voltage amplitude. In this paper, emergency control in distribution systems is discussed by using the proposed multifunctional DVR control strategy.
Also, the multiloop controller using the Posicast and P+Resonant controllers is proposed in order to improve the transient response and eliminate the steady-state error in DVR response, respectively. The proposed algorithm is applied to some disturbances in load voltage caused by induction motors starting, and a three-phase short circuit fault. Also, the capability of the proposed DVR has been tested to limit the downstream fault current.
The current limitation will restore the point of common coupling (PCC) (the bus to which all feeders under study are connected) voltage and protect the DVR itself.
The innovation here is that the DVR acts as a virtual impedance with the main aim of protecting the PCC voltage during downstream fault without any problem in real power injection into the DVR. Simulation results show the capability of the DVR to control the emergency conditions of the distribution systems.

FLEXIBLE D-STATCOM PERFORMANCE AS A FLEXIBLE DISTRIBUTED GENERATION IN MITIGATING FAULTS
ABSTRACT
This paper proposes a flexible D-STATCOM (Distribution Static COMpensator) and its new controller system, that be able to both mitigate all types of faults and operate as a Distributed Generation (DG), when it supplies power to sensitive loads while the main utility source is disconnected (i.e. it is under islanded operating condition).
Thus D-STATCOM operates same as a flexible DG (FDG) and consequently, it is called Flexible D-STATCOM (FD-STATCOM). This paper validates the performance of FD-STATCOM system to mitigate power quality problems and improve distribution system performance under all types of system related disturbances and system unbalanced faults, such as Line-to-Line (LL) and Double Line to Ground (DLG) faults and supplies power to sensitive loads under islanding condition.
In this paper, the 12-pulse D-STATCOM configuration with IGBT is designed and the graphic based models of the D-STATCOM are developed using the PSCAD/EMTDC electromagnetic transient simulation program.
The reliability and robustness of the control schemes in the system response to the voltage disturbances caused by LL and DLG faults and islanded operating condition are obviously proved in the simulation results.

MATRIX CONVERTER-BASED UNIFIED POWER-FLOW CONTROLLERS ADVANCED DIRECT POWER CONTROL METHOD
ABSTRACT
This paper presents a direct power control (DPC) for three-phase matrix converters operating as unified power flow controllers (UPFCs). Matrix converters (MCs) allow the direct ac/ac power conversion without dc energy storage links; therefore, the MC-based UPFC (MC-UPFC) has reduced volume and cost, reduced capacitor power losses, together with higher reliability.
Theoretical principles of direct power control (DPC) based on sliding mode control techniques are established for an MC-UPFC dynamic model including the input filter. As a result, line active and reactive power, together with ac supply reactive power, can be directly controlled by selecting an appropriate matrix converter switching state guaranteeing good steady-state and dynamic responses.
Experimental results of DPC controllers for MC-UPFC show decoupled active and reactive power control, zero steady-state tracking error, and fast response times.
Compared to an MC-UPFC using active and reactive power linear controllers based on a modified Venturini high-frequency PWM modulator, the experimental results of the advanced DPC-MC guarantee faster responses without overshoot and no steady-state error, presenting no cross-coupling in dynamic and steady-state responses.

MODELING, ANALYSIS, AND CONTROL FOR THE RECTIFIER OF HYBRID HVDC SYSTEMS FOR DFIG-BASED WIND FARMS
ABSTRACT
In order to improve the dynamic performance of the hybrid HVdc system for doubly fed induction generator wind farms, this paper presents the modeling, analysis, and control methods for its line-commutated rectifier.
First, the state variable model of the rectifier subsystem on the reference frame is derived considering different control modes of the current source inverter subsystem. Then, the ac current dynamic of the rectifier subsystem is quantitatively analyzed based on the eigenvalue analysis method.
According to the analysis results, a double loop control scheme is designed: the inner loop utilizes the inverse system control technique plus a switchable phase-lead compensator, and the outer loop implements an ordinary propotional-integral controller.
Finally, the validity of the quantitative analysis method and the superiority of the proposed control scheme are verified by Simulink / SimPowerSystems simulations.

AVERAGE CURRENT CONTROLLED SWITCHING REGULATORS WITH CASCADE BOOST CONVERTERS
Power Electronics
ABSTRACT
A controller design methodology for an n-stage cascade boost converter is given using average current-mode control. This class of converters has n-LC filters; thus, it will exhibit 2n-order characteristic dynamics.
The proposed scheme employs the inductor current of the input stage and the capacitor voltage of the output stage; thus, there are (n-1) capacitor voltages and (n-1) inductor currents that are not used for feedback purposes.
The sensed current can also be used for one-cycle overload protection; therefore the full benefits of current-mode control are maintained. Owing to the fact that this scheme uses only a reduced set of variables for feedback, it is important to study the internal stability.
The results given in this study allow the designer to easily pinpoint the control circuit parameters that optimise the converter-s performance. Experimental results are given for a 100 W switching regulator where the robustness of the proposed controller is tested under changes in the input voltage and output load.

NONISOLATED HIGH STEP-UP STACKED CONVERTER BASED ON BOOST-INTEGRATED ISOLATED CONVERTER
Power Electronics, IEEE Transactions on
ABSTRACT
To obtain a high step-up gain with high efficiency in nonisolated applications, a high step-up technique based on isolated-type converters is introduced in this paper. By stacking the secondary side of an isolated converter in addition to its primary side, a high step-up conversion ratio and a distributed voltage stress can be achieved.
Moreover, a careful choice of an isolated converter can provide zero-voltage switching, continuous input current, and reduced reverse recovery on diodes.
Based on a conventional voltage-doubler-rectifier boost-integrated half-bridge converter, the derived converter satisfies all these features, which make it suitable for high step-up applications.
The operational principle and characteristics of the proposed converter are presented, and verified experimentally with a 135-W, 24-V input, 250-V output prototype converter for a LED driver.

SOFT-SWITCHING TECHNIQUES FOR EFFICIENCY GAINS IN FULL-BRIDGE FUEL CELL POWER CONVERSION
Power Electronics, IEEE Transactions on
ABSTRACT
This paper presents a set of novel soft-switching techniques to increase the power conversion efficiency in fuel cell (FC) systems using a full-bridge topology. For this purpose, a special right-aligned modulation sequence is developed to minimize conduction losses while maintaining soft-switching characteristics in the MOSFETs.
Traditional auxiliary elements in the primary, such as series inductors that are impractical for realizing due to the extreme input current, are avoided and reflected to the output of the rectifier to minimize circulating current and generate soft transitions in the output diodes.
As a result, the proposed combined techniques successfully reduce conduction losses, minimize reverse-recovery losses in the output rectifiers, minimize transformer ringing, and ensure low stress in all the switches. The high efficiency is maintained in the entire range of loading conditions (0%-100%) while taking into consideration remarkable challenges associated with FC power conversion: high input current, low voltage and poor regulation, and wide range of loading conditions.
A detailed analysis of the techniques for efficiency gains are presented and a phase-shift zero-voltage switching topology is employed as a reference topology to highlight the mechanisms for performance enhancement and the advantages in the use of the special modulation.
Experimental results of a 1-kW power converter are presented to validate the efficiency gains, illustrate the benefits of the special modulation, and demonstrate the soft-switching transitions.

INTERLEAVED ACTIVE-CLAMPING CONVERTER WITH ZVS/ZCS FEATURES
Power Electronics, IEEE Transactions on
ABSTRACT
In this paper, an interleaved soft-switching dc-to-dc converter configuration is proposed. It consists of two parts: the primary side is a constant-frequency asymmetrical converter with active-clamp feature and the secondary side is a series-resonant tank circuit.
The active-clamp circuit recycles the energy stored in the magnetizing inductance of transformer to allow main/auxiliary switches turn-ON at zero-voltage switching and clamps the voltage stress of the main switches. Series-resonant tank circuit employs the transformer leakage inductance and secondary resonant capacitance to achieve zero-current switching of the output diodes.
The circuit features constant-frequency operation and soft switching for both the transistors and the diodes. Interleaving operation of this configuration combines the aforementioned benefits and small output capacitor.
Theoretical analysis and computer simulation of the converter were given. An 80-KHz 500-W experimental circuit of the proposed converter was demonstrated.

INHERENT CLAMP FLYBACK–BUCK CONVERTER WITH WINDING CROSS-COUPLED INDUCTORS
Power Electronics, IET
ABSTRACT
An isolated interleaved buck-type converter is deduced by inserting a third winding of the coupled inductor to each phase of the interleaved flyback converter.
By making some topology modifications and adding one small clamp capacitor, the existed power switches of the derived flyback-buck converter can serve as the clamp switches for the interleaved phase to absorb the leakage energy of the coupled inductor and to reduce the switch turn-off voltage stress, which simplifies the circuit configuration and improves the circuit reliability.
Furthermore, the current falling rate of the output diodes is limited by the leakage inductance to alleviate the output diode reverse-recovery problem. Finally, a 160-W 200-V-input 15-V-output prototype is built and tested to verify the improved performance of the proposed converter.

A NOVEL CONTROL SCHEME OF SYNCHRONOUS BUCK CONVERTER FOR ZVS IN LIGHT-LOAD CONDITION
Power Electronics, IEEE Transactions on
ABSTRACT
This paper proposes a new control technology that enables a synchronous rectifier (SR) buck converter to realize zero voltage switching (ZVS) in light load condition. The SR control technique is applicable to DC low voltage output because the replacement of output rectifier diode by MOSFET can minimize conduction losses and increase the efficiency of the whole circuit.
However, the technique cannot achieve good efficiency in light load condition. The control technique introduced in this paper enables a SR buck converter to carry out ZVS in light load condition to increase efficiency. No extra auxiliary switches or RLC passive components are required; thus, it is low cost and easy to control.
The output of buck converter with 5V/25W featured by SR is developed in this paper; the availability of the technique introduced herein is also proven. The experimental results are satisfactory.

INTERLEAVED FOUR-PHASE BUCK-BASED CURRENT SOURCE WITH CENTER-TAPPED ENERGY-RECOVERY SCHEME FOR ELECTRICAL DISCHARGE MACHINING
Power Electronics, IEEE Transactions on

ABSTRACT
This paper proposes a center-tapped energy-recovery scheme used in the interleaved four-phase buck-based current source in continuous-conduction mode for electrical discharge machining (EDM).
A pulse-machining current with high-slew rate is required for the EDM. Using the interleaving technique, the output-current slew rate of the buck-based current source can be improved because of the paralleled inductors at the start of discharge.
The proposed center-tapped energy-recovery scheme provides a major path for the inductor to release its stored energy to avoid high-voltage stress in the output terminal when the gap is in the high-impedance state.
The energy stored in the inductor is recovered to the input capacitor, and can be reused for machining. The experimental results are provided as the verification of the high-output-current slew rate and the energy recovery when the gap is in high-impedance state.

A SERIES-TUNED INDUCTIVE-POWER-TRANSFER PICKUP WITH A CONTROLLABLE AC-VOLTAGE OUTPUT
Power Electronics, IEEE Transactions on
ABSTRACT
This paper presents a new type of series ac-processing pickup used in inductive-power-transfer applications. The proposed pickup uses an ac switch operating under zero-current-switching conditions in series with a resonant network to produce a controllable ac voltage source suitable for driving incandescent lights. When a rectifier is cascaded onto this pickup, it can also produce a precisely controlled dc voltage.
This topology eliminates the need to use an extra buck converter after the traditional series pickup for controlling the output load voltage to a desired value, which may be different from the induced voltage of the pickup.
Furthermore, this pickup has the ability to control the inductor current directly, and hence, eliminate the transient inrush current at startup for the series-tuned resonant tank. The circuit is analytically analyzed and the maximum efficiency for a 1.2-kW prototype is measured to be 93%.

BRIDGELESS HIGH-POWER-FACTOR BUCK CONVERTER
Power Electronics, IEEE Transactions on
ABSTRACT
A bridgeless buck power factor correction rectifier that substantially improves efficiency at low line of the universal-line range is introduced. By eliminating input bridge diodes, the proposed rectifier's efficiency is further improved.
Moreover, the rectifier doubles its output voltage, which extends useable energy of the bulk capacitor after a dropout of the line voltage. The operation and performance of the proposed circuit was verified on a 700-W, universal-line experimental prototype operating at 65 kHz.
The measured efficiencies at 50% load from 115 and 230 V line are both close to 96.4%. The efficiency difference between low line and high line is less than 0.5% at full load. A second-stage half-bridge converter was also included to show that the combined power stages easily meet Climate Saver Computing Initiative Gold Standard.

The main concept of the new method is to use the inverter to perform off-line tests for quality assessment of the vulnerable components in the inverter, cable, and induction motor automatically whenever the motor is stopped.
This new approach is suitable for monitoring system components that deteriorate gradually to failure, if the degradation is observable. Off-line test methods for monitoring the quality of the 1) dc-link aluminum electrolytic capacitor; 2) electrical connections; 3) cable and stator winding insulation; 4) stator core; and 5) rotor bar are presented along with a summary of the failure mechanism and existing test methods.
It will be shown that the new strategy can be implemented with minimal hardware requirements, and that it has many advantages over existing off-line and on-line tests.
An experimental study performed under simulated fault conditions for each component shows that the method provides a reliable and sensitive indication of drive system problems for reliable, efficient, and safe operation.

A NEW SINGLE-PHASE TO THREE-PHASE CONVERTER USING QUASI Z-SOURCE NETWORK
Applied Power Electronics

ABSTRACT
This paper introduces a new cost effective structure of a 4-switch single-phase to three-phase converter using a Quasi Z-source (QZs) network for induction motor drive applications.
In comparison to the traditional 6-switch structure, the proposed circuit reduces the cost of the system, switching losses and the complexity of the control method as well as the interface circuits used to make the trigger signals.
In addition, The Quasi Z-Source network, similar to the Z-Source network uses a unique LC network with added advantages, such as; lower component ratings, reduced source stress, reduced component count and simplified control strategies for Adjustable Motor Drives (ASD) which require large range of gain.
By controlling the zero shoot-through duty cycle, the converter can generate any desired output voltage, even greater than the supply voltage. Consequently, the converter is capable of extending the output voltage range, improving the power factor and reliability, reduces line harmonics and provides ride-through ability at the voltage sag interval. Simulation results on the proposed converter have indicated its efficiency and potential for further development.

OPEN LOOP V/F CONTROL OF INDUCTION MOTOR BASED ON HYBRID PWM WITH REDUCED TORQUE RIPPLE
ABSTRACT
Voltage source inverter (VSI) fed induction motors are widely used in variable speed applications. Space Vector Pulse Width Modulation (SVPWM) has become the successful techniques to construct three phase sine wave Voltage Source Inverter (VSI) parallel to control three-phase induction motor using v/f control. Because of the low maintenance and robustness induction motors have many applications in the industries.
The speed control of induction motor is more important to achieve maximum torque and efficiency. VSI fed induction motor produces a pulsating torque due to the application of non sinusoidal voltages. Among the various modulation strategies Space Vector pulse width Modulation Technique is the efficient one because it has better spectral performance and output voltage is more closed to sinusoidal.
Torque pulsation is strongly influenced by PWM technique used. This paper compares the torque ripples of convectional space vector PWM with hybrid PWM techniques. In hybrid PWM both continuous PWM and discontinuous PWM techniques are employed.
The open loop V/f control of induction motor with hybrid PWM shows better reduction in torque ripples when compared with conventional space vector PWM technique. The simulated design is tested using MATLAB 7.8.

ON DYNAMIC EFFECTS INFLUENCING IGBT LOSSESIN SOFT-SWITCHING CONVERTERSIN SOFT-SWITCHING CONVERTERS
Power Electronics, IEEE Transactions on
ABSTRACT
Two different dynamic effects influencing the insulated gate bipolar transistor (IGBT) losses in soft-switching converters are demonstrated. The first one, the Dynamic tail-charge effect shows that the tail charge is dependent not only on the absolute value of the current at turn-off, but also on the dynamics of the current.
This effect may have a significant impact on the optimization of zero-current-switching converters. The Dynamic conduction losses originate from the conductivity modulation lag of the IGBT. It is shown by experiments that the on-state losses depend on the operating frequency.
Different methods to accurately determine the on-state losses are evaluated. It was found that the best method is an indirect measurement, where the stray inductance is identified by the use of an oscillating circuit. The experiments are performed under a sinusoidal current excitation at a fixed amplitude (150 A) for different frequencies (up to 104 kHz).
The switching devices used are IGBT modules rated 300-400 A/1200 V in a bridge-leg configuration. From the experiments performed, it is found that IGBTs of a modern punch-though (PT) designs have the lowest losses in the series-loaded resonant converters studied in this paper.

ASYMMETRIC DUTY CONTROL OF A DUAL-HALF-BRIDGE DC/DC CONVERTER FOR SINGLE-PHASE DISTRIBUTED GENERATORS
Power Electronics, IEEE Transactions on
ABSTRACT
A dual-half-bridge (DHB) converter is integrated with a half-bridge 60-Hz inverter as a converter/inverter system for a small distributed generator. This topology provides an isolation between the power source and the load with a 100-kHz transformer, and therefore, the system volume is small.
On the other hand, it reduces the number of switching devices greatly. However, the half-bridge inverter causes severe capacitor-voltage fluctuations.
The unbalanced voltage problem can be solved by controlling the converter switching: In addition to the conventional phase-shift control method, an asymmetric charging method is used that charges the upper and lower secondary capacitors differently.
This means that the voltage imbalance is corrected by adjusting the switching time of the secondary switches. Furthermore, a decoupling control algorithm can be derived from this approach. The usefulness of this method is then validated by simulation and experimental results

MODELING AND ANALYSIS OF GRID HARMONIC DISTORTION IMPACT OF AGGREGATED DG INVERTERS
Power Electronics, IEEE Transactions on

ABSTRACT
This paper proposes an impedance-based analytical method for modeling and analysis of harmonic interactions between the grid and aggregated distributed generation (DG) inverters.
The root cause of harmonic interaction/resonance problems is the impedance-network quasi-resonance between the effective output impedance of the inverter and the equivalent grid impedance at the connection point. Starting with the output impedance modeling of an inverter, a Norton model of the inverter is derived. Comparing with the switching model and the average model of the inverter, simulation results show the effectiveness of the model.
This paper proposes that impedance limits should be specified and used as an extra design constraint for DG inverters in order to minimize the harmonic distortion impact on the grid.
Assuming the impedance models of individual inverters and local loads within a distribution grid are known, especially in the case of new grids under construction, harmonic interactions between the grid and a certain number of DG inverters can be preliminarily estimated.

INTERLEAVED SOFT-SWITCHING BOOST CONVERTER FOR PHOTOVOLTAIC POWER-GENERATION SYSTEM
Power Electronics, IEEE Transactions on

ABSTRACT
In this paper, a interleaved soft switching boost converter (ISSBC) for a photovoltaic (PV) power-generation system is proposed. The topology used raises the efficiency for the dc/dc converter of the PV power conditioning system (PVPCS), and it minimizes switching losses by adopting a resonant soft-switching method.
A detailed mode analysis of the proposed topology is presented. The feasibility of the proposed topology is experimentally verified for a 1.2-kW prototype.
The experimental results imply that 97.28% efficiency is achieved under the full-load condition. Consequently, it is confirmed that the overall efficiency is increased by about 1.5% compared with the conventional hard switching interleaved boost converter

Power Electronics, IEEE Transactions on

ABSTRACT
This paper introduces a single-phase digital power-factor correction (PFC) control approach that requires no input voltage sensing or explicit current-loop compensation, yet results in low-harmonic operation over a universal input voltage range and loads ranging from high-power operation in continuous conduction mode down to the near-zero load.
The controller is based on low-resolution A/D converters and digital pulsewidth modulator, requires no microcontroller or DSP programming, and is well suited for a simple, low-cost integrated-circuit realization, or as a hardware description language core suitable for integration with other power control and power management functions. Experimental verification results are shown for a 300-W boost PFC rectifier.

DETECTING BACKGROUND SETTING FOR DYNAMIC SCENE
ABSTRACT
Processing Real-Time image sequence is now possible because of advancement of technological developments in digital signal processing, wide-band communication, and high-performance VLSI.
With the developments in video technology, the surveillance system can be built with some low cost gadget such as the web-camera. In this modern life with increasing number of crime rate, people in society need for security and safety; video surveillance has become important reason to oppose threats of crime and terrorism.
The most fundamental part of surveillance is foreground detection, which is retrieval of an object of interest. The object of interest can remodel by common background subtraction technique. There is some problem arises by using this technique, where because of variation of light source, the background constantly changes.
The intensity of pixel changes throughout the object detection takes place. Intensity of pixel value changes leads to improper foreground detection, the background detected as foreground object.
This paper proposes a method to model and update the background of the scene by intersection solving method.

A new mapping scheme and its hardware implementation to error-freely compute the Daubechies 8-tap wavelet transform is presented. The multidimensional technique maps the irrational transform basis coefficients with integers and results in considerable reduction in hardware and power consumption.
When implemented in Xilinx FPGA, the scheme costs 518 logic cells, 186 registers and runs at a frequency of 71MHz. While comparing with finite-precision architecture, the proposed scheme yields a reduction of 15% in hardware and 41% in power consumption for similar image reconstruction, and noticeable improvement in image reconstruction quality.

PERFORMANCE ANALYSIS OF INTEGER WAVELET TRANSFORM FOR IMAGE COMPRESSION
ABSTRACT
For image compression, it is very necessary that the selection of transform should reduce the size of the resultant data as compared to the original data set .In this paper, a new lossless image compression method is proposed.
For continuous and discrete time cases, wavelet transform and wavelet packet transform has emerged as popular techniques. While integer wavelet using the lifting scheme significantly reduces the computation time, we propose a completely new approach for further speeding up the computation.
First, wavelet packet transform (WPT) and lifting scheme (LS) are described. Then an application of the LS to WPT is presented which leads to the generation of integer wavelet packet transform (IWPT).
The proposed method, Integer Wavelet Packet Transform (IWPT) yields a representation which can be lossless, as it maps an integer valued sequence onto the integer valued coefficients. The idea of Wavelet Packet Tree is used to transform the still and color images.
IWPT tree can be built by iterating the single wavelet decomposition step on both the low-pass and high-pass branches, with rounding off in order to achieve the integer transforms. Thus, the proposed method provides good compression ratio.

AUTOMATIC ROAD EXTRACTION USING HIGH RESOLUTION SATELLITE IMAGES BASED ON LEVEL SET AND MEAN SHIFT METHODS
ABSTRACT
Analysis of high resolution satellite images has been an important research topic for urban analysis. One of the important features of urban areas in urban analysis is the automatic road network extraction. Two approaches for road extraction based on Level Set and Mean Shift methods are proposed.
From an original image it is difficult and computationally expensive to extract roads due to presences of other road-like features with straight edges. The image is preprocessed to improve the tolerance by reducing the noise (the buildings, parking lots, vegetation regions and other open spaces) and roads are first extracted as elongated regions, non-linear noise segments are removed using a median filter (based on the fact that road networks constitute large number of small linear structures). Then road extraction is performed using Level Set and Mean Shift method.
Finally the accuracy for the road extracted images is evaluated based on quality measures. The 1m resolution IKONOS data has been used for the experiment.

A NEW ADAPTIVE WEIGHT ALGORITHM FOR SALT AND PEPPER NOISE REMOVAL
ABSTRACT
A new adaptive weight algorithm is developed for the removal of salt and pepper noise. It consists of two major steps, first to detect noise pixels according to the correlations between image pixels, then use different methods based on the various noise levels.
For the low noise level, neighborhood signal pixels mean method is adopted to remove the noise, and for the high noise level, an adaptive weight algorithm is used.
Experiments show the proposed algorithm has advantages over regularizing methods in terms of both edge preservation and noise removal, even for heavily contaminated image with noise level as high as 90%, it still can get a significant performance.

REMOVAL OF HIGH DENSITY SALT AND PEPPER NOISE THROUGH MODIFIED DECISION BASED UNSYMMETRIC TRIMMED MEDIAN FILTER
ABSTRACT
A modified decision based unsymmetrical trimmed median filter algorithm for the restoration of gray scale, and color images that are highly corrupted by salt and pepper noise is proposed in this paper.
The proposed algorithm replaces the noisy pixel by trimmed median value when other pixel values, 0's and 255's are present in the selected window and when all the pixel values are 0's and 255's then the noise pixel is replaced by mean value of all the elements present in the selected window.
This proposed algorithm shows better results than the Standard Median Filter (MF), Decision Based Algorithm (DBA), Modified Decision Based Algorithm (MDBA), and Progressive Switched Median Filter (PSMF).
The proposed algorithm is tested against different grayscale and color images and it gives better Peak Signal-to-Noise Ratio (PSNR) and Image Enhancement Factor (IEF).

ADIABATIC TECHNIQUE FOR ENERGY EFFICIENT LOGIC CIRCUITS DESIGN
ABSTRACT
The Energy dissipation in conventional CMOS circuits can be minimized through adiabatic technique. By adiabatic technique dissipation in PMOS network can be minimized and some of energy stored at load capacitance can be recycled instead of dissipated as heat.
But the adiabatic technique is highly dependent on parameter variation. With the help of TSPICE simulations, the energy consumption is analyzed by variation of parameter.
In analysis, two logic families, ECRL (Efficient Charge Recovery Logic) and PFAL (Positive Feedback Adiabatic Logic) are compared with conventional CMOS logic for inverter and 2:1 multiplexer circuits. It is find that adiabatic technique is good choice for low power application in specified frequency range.

DESIGN AND FPGA IMPLEMENTATION OF MODIFIED DISTRIBUTIVE ARITHMETIC BASED DWT-IDWT PROCESSOR FOR IMAGE COMPRESSION
ABSTRACT
Image compression is one of the major image processing techniques that is widely used in medical, automotive, consumer and military applications. Discrete wavelet transforms is the most popular transformation technique adopted for image compression.
Complexity of DWT is always high due to large number of arithmetic operations. In this work a modified Distributive Arithmetic based DWT architecture is proposed and is implemented on FPGA. The modified approach consumes area of 6% on Virtex-II pro FPGA and operates at 134 MHz.
The modified DA-DWT architecture has a latency of 44 clock cycles and a throughput of 4 clock cycles. This design is twice faster than the reference design and is thus suitable for applications that require high speed image processing algorithms.

ABSTRACT
Field Programmable Gate Array (FPGA) technology has become a viable target for the implementation of real time algorithms suited to video image processing applications.
The unique architecture of the FPGA has allowed the technology to be used in many applications encompassing all aspects of video image processing. Among those algorithms, linear filtering based on a 2D convolution, and non-linear 2D morphological filters, represent a basic set of image operations for a number of applications.

ABSTRACT
This paper enumerates low power, high speed design of flip-flop having less number of transistors and only one transistor being clocked by short pulse train which is true single phase clocking (TSPC) flip-flop.
Compared to Conventional flip-flop, it has 5 Transistors and one transistor clocked, thus has lesser size and lesser power consumption. It can be used in various applications like digital VLSI clocking system, buffers, registers, microprocessors etc.
The analysis for various flip flops and latches for power dissipation and propagation delays at 0.13 Â¿m and 0.35 Â¿m technologies is carried out. The leakage power increases as technology is scaled down.

LOW-POWER AND AREA-EFFICIENT CARRY SELECT ADDER
ABSTRACT
Carry Select Adder (CSLA) is one of the fastest adders used in many data-processing processors to perform fast arithmetic functions. From the structure of the CSLA, it is clear that there is scope for reducing the area and power consumption in the CSLA.
This work uses a simple and efficient gate-level modification to significantly reduce the area and power of the CSLA. Based on this modification 8-, 16-, 32-, and 64-b square-root CSLA (SQRT CSLA) architecture have been developed and compared with the regular SQRT CSLA architecture.
The proposed design has reduced area and power as compared with the regular SQRT CSLA with only a slight increase in the delay. This work evaluates the performance of the proposed designs in terms of delay, area, power, and their products by hand with logical effort and through custom design and layout in 0.18-$mu$m CMOS process technology. The results analysis shows that the proposed CSLA structure is better than the regular SQRT CSLA.

A PIPELINE VLSI ARCHITECTURE FOR HIGH-SPEED COMPUTATION OF THE 1-D DISCRETE WAVELET TRANSFORM
ABSTRACT
In this paper, a scheme for the design of a high-speed pipeline VLSI architecture for the computation of the 1-D discrete wavelet transform (DWT) is proposed. The main focus of the scheme is on reducing the number and period of clock cycles for the DWT computation with little or no overhead on the hardware resources by maximizing the inter- and intrastage parallelisms of the pipeline.
The interstage parallelism is enhanced by optimally mapping the computational load associated with the various DWT decomposition levels to the stages of the pipeline and by synchronizing their operations. The intrastage parallelism is enhanced by decomposing the filtering operation equally into two subtasks that can be performed independently in parallel and by optimally organizing the bitwise operations for performing each subtask so that the delay of the critical data path from a partial-product bit to a bit of the output sample for the filtering operation is minimized.
It is shown that an architecture designed based on the proposed scheme requires a smaller number of clock cycles compared to that of the architectures employing comparable hardware resources. In fact, the requirement on the hardware resources of the architecture designed by using the proposed scheme also gets improved due to a smaller number of registers that need to be employed.
Based on the proposed scheme, a specific example of designing an architecture for the DWT computation is considered. In order to assess the feasibility and the efficiency of the proposed scheme, the architecture thus designed is simulated and implemented on a field-programmable gate-array board.
It is seen that the simulation and implementation results conform to the stated goals of the proposed scheme, thus making the scheme a viable approach for designing a practical and realizable architecture for real-time DWT computation.

DUAL STACK METHOD: A NOVEL APPROACH TO LOW LEAKAGE AND SPEED POWER PRODUCT VLSI DESIGN
ABSTRACT
The development of digital integrated circuits is challenged by higher power consumption. The combination of higher clock speeds, greater functional integration, and smaller process geometries has contributed to significant growth in power density. Scaling improves transistor density and functionality on a chip.
Scaling helps to increase speed and frequency of operation and hence higher performance. As voltages scale downward with the geometries threshold voltages must also decrease to gain the performance advantages of the new technology but leakage current increases exponentially.
Today leakage power has become an increasingly important issue in processor hardware and software design. In 65 nm and below technologies, leakage accounts for 30-40% of processor power.
In this paper, we propose a new dual stack approach for reducing both leakage and dynamic powers. Moreover, the novel dual stack approach shows the least speed power product when compared to the existing methods.

POWER MANAGEMENT OF MIMO NETWORK INTERFACES ON MOBILE SYSTEMS
Very Large Scale Integration (VLSI) Systems,
IEEE Transactions on
ABSTRACT
High-speed wireless network interfaces are among the most power-hungry components on mobile systems. This is particularly true for multiple-input-multiple-output (MIMO) network interfaces which use multiple RF chains simultaneously.
In this paper, we present a novel power management solution for MIMO network interfaces on mobile systems, called antenna management. The key idea is to adaptively disable a subset of antennas and their RF chains to reduce circuit power consumption, when the capacity improvement of using a large number of antennas is small. Antenna management judiciously determines the number of active antennas to minimize energy per bit while satisfying the data rate requirement.
This work provides both theoretical framework and system design of antenna management. We first present an algorithm that efficiently solves the problem of minimizing energy per bit and, then offer its 802.11n-compliant system designs.
We employ both Matlab-based simulation and prototype-based experiment to validate the energy efficiency benefit of antenna management. The results show that antenna management can achieve 21% one-end energy per bit reduction to the front end of the MIMO network interface, compared to a static MIMO configuration that keeps all antennas active.

HIGH-SPEED LOW-POWER VITERBI DECODER DESIGN FOR TCM DECODERS
Very Large Scale Integration (VLSI) Systems
IEEE Transactions on
ABSTRACT
High-speed, low-power design of Viterbi decoders for trellis coded modulation (TCM) systems is presented in this paper. It is well known that the Viterbi decoder (VD) is the dominant module determining the overall power consumption of TCM decoders.
We propose a pre-computation architecture incorporated with $T$-algorithm for VD, which can effectively reduce the power consumption without degrading the decoding speed much. A general solution to derive the optimal pre-computation steps is also given in the paper.
Implementation result of a VD for a rate-3/4 convolutional code used in a TCM system shows that compared with the full trellis VD, the precomputation architecture reduces the power consumption by as much as 70% without performance loss, while the degradation in clock speed is negligible

IEEE Transactions on
ABSTRACT
A current source with a small current error has been proposed to maintain the bandwidth of the system without an increase in power consumption for a margin. It minimizes the current error under process, supply voltage, and temperature (PVT) variations.
Because the on-resistance of the nMOS array is self-calibrated digitally by an on-chip digital PVT detector, a current error of only ${pm}$ 2% is achieved.
The current source has been implemented in an 80-nm CMOS process, occupies 0.018 mm$^{2}$ and consumes 94.9 $mu$ W at a supply voltage of 1.0 V.

LOW-COMPLEXITY SEQUENTIAL SEARCHER FOR ROBUST SYMBOL SYNCHRONIZATION IN OFDM SYSTEMS
Very Large Scale Integration (VLSI) Systems
IEEE Transactions on
ABSTRACT
Based on the frequency-domain analog-to-digital conversion (FD ADC), this work builds a low-complexity sequential searcher for robust symbol synchronization in a 4$,times,$ 4 FD multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) modem.
The proposed scheme adopts a symbol-rate sequential search with simple cross-correlation metric to recover symbol timing over the frequency domain. Simulation results show that the detection error is less than 2% at signal-to-noise ratio (SNR) $leqq $5 dB. Performance loss is not significant when carrier frequency offset (CFO) $leqq $100 ppm.
Using an in-house 65-nm CMOS technology, the proposed solution occupies 84.881 k gates and consumes 5.2 mW at 1.0 V supply voltage. This work makes the FD ADC more attractive to be adopted in high throughput OFDM systems

AN AUTONOMOUS VECTOR/SCALAR FLOATING POINT COPROCESSOR FOR FPGAS
ABSTRACT
We present a Floating Point Vector Coprocessor that works with the Xilinx embedded processors. The FPVC is completely autonomous from the embedded processor, exploiting parallelism and exhibiting greater speedup than alternative vector processors.
The FPVC supports scalar computation so that loops can be executed independently of the main embedded processor. Floating point addition, multiplication, division and square root are implemented with the Northeastern University VFLOAT library.
The FPVC is parameterized so that the number of vector lanes and maximum vector length can be easily modified. We have implemented the FPVC on a Xilinx Virtex 5 connected via the Processor Local Bus (PLB) to the embedded PowerPC. Our results show more than five times improved performance over the PowerPC augmented with the Xilinx Floating Point Unit on applications from linear algebra: QR and Cholesky decomposition.

BUILDING AN AMBA AHB COMPLIANT MEMORY CONTROLLER
ABSTRACT
Microprocessor performance has improved rapidly these years. In contrast, memory latencies and bandwidths have improved little. The result is that the memory access time has been a bottleneck which limits the system performance.

4 BIT SFQ MULTIPLIER BASED ON BOOTH ENCODER
ABSTRACT
We have designed a 2-bit Booth encoder with Josephson Transmission Lines (JTLs) and Passive Transmission Lines (PTLs) by using cell-based techniques and tools. The Booth encoding method is one of the algorithms to obtain partial products.
With this method, the number of partial products decreases down to the half compared to the AND array method. We have fabricated a test chip for a multiplier with a 2-bit Booth encoder with JTLs and PTLs. It has a processing frequency of 20 GHz with the bias margin ±25%.
The frequency of this circuit increases up to 45 GHz with the bias voltage by 25% increased from the design voltage. The circuit area of the multiplier designed with the Booth encoder method is compared to that designed with the AND array method.

HIGH-ACCURACY FIXED-WIDTH MODIFIED BOOTH MULTIPLIERS FOR LOSSY APPLICATIONS
ABSTRACT
The fixed-width multiplier is attractive to many multimedia and digital signal processing systems which are desirable to maintain a fixed format and allow a little accuracy loss to output data. This paper presents the design of high-accuracy fixed-width modified Booth multipliers.
To reduce the truncation error, we first slightly modify the partial product matrix of Booth multiplication and then derive an effective error compensation function that makes the error distribution be more symmetric to and centralized in the error equal to zero, leading the fixed-width modified Booth multiplier to very small mean and mean-square errors.
In addition, a simple compensation circuit mainly composed of the simplified sorting network is also proposed. Compared to the previous circuits, the proposed error compensation circuit can achieve a tiny mean error and a significant reduction in mean-square error (e.g., at least 12.3% reduction for the 16-bit fixed-width multiplier) while maintaining the approximate hardware overhead.
Furthermore, experimental results on two real-life applications also demonstrate that the proposed fixed-width multipliers can improve the average peak signal-to-noise ratio of output images by at least 2.0 dB and 1.1 dB, respectively.

EFFICIENT WEIGHTED MODULO 2N+1 ADDERS BY PARTITIONED PARALLEL-PREFIX COMPUTATION AND ENHANCED CIRCULAR CARRY GENERATION
ABSTRACT
In this paper, we propose a low complexity design of weighted modulo 2n+1 adder, derived by decomposition of parallel-prefix computation into several blocks of smaller input bit-widths.
Besides, we have proposed a novel enhanced circular carry generation (ECCG) unit to process the carry-bits produced by all the parallel-prefix computation units (of small input bit-widths) to obtain the final modulo sum efficiently in terms of area-delay product.
We have implemented the proposed adders using 0.13 μm CMOS technology; and from the synthesis results we find that our proposed adder outperforms the previously reported weighted modulo 2n+1 adders. It offers a saving of area-delay product up to 49% over the existing methods.

DESIGN AND CHARACTERIZATION OF PARALLEL PREFIX ADDERS USING FPGAS
ABSTRACT
Parallel-prefix adders (also known as carry-tree adders) are known to have the best performance in VLSI designs. However, this performance advantage does not translate directly into FPGA implementations due to constraints on logic block configurations and routing overhead.
This paper investigates three types of carry-tree adders (the Kogge-Stone, sparse Kogge-Stone, and spanning tree adder) and compares them to the simple Ripple Carry Adder (RCA) and Carry Skip Adder (CSA).
These designs of varied bit-widths were implemented on a Xilinx Spartan 3E FPGA and delay measurements were made with a high-performance logic analyzer. Due to the presence of a fast carry-chain, the RCA designs exhibit better delay performance up to 128 bits.
The carry-tree adders are expected to have a speed advantage over the RCA as bit widths approach 256.

HIGH SPEED ASIC DESIGN OF COMPLEX MULTIPLIER USING VEDIC MATHEMATICS
ABSTRACT
Vedic Mathematics is the ancient methodology of Indian mathematics which has a unique technique of calculations based on 16 Sutras (Formulae). A high speed complex multiplier design (ASIC) using Vedic Mathematics is presented in this paper.
The idea for designing the multiplier and adder/sub-tractor unit is adopted from ancient Indian mathematics “Vedas”. On account of those formulas, the partial products and sums are generated in one step which reduces the carry propagation from LSB to MSB.
The implementation of the Vedic mathematics and their application to the complex multiplier ensure substantial reduction of propagation delay in comparison with DA based architecture and parallel adder based implementation which are most commonly used architectures.
The functionality of these circuits was checked and performance parameters like propagation delay and dynamic power consumption were calculated by spice spectre using standard 90nm CMOS technology.
The propagation delay of the resulting (16, 16)×(16, 16) complex multiplier is only 4ns and consume 6.5 mW power. We achieved almost 25% improvement in speed from earlier reported complex multipliers, e.g. parallel adder and DA based architectures.

A LIGHTWEIGHT HIGH-PERFORMANCE FAULT DETECTION SCHEME FOR THE ADVANCED ENCRYPTION STANDARD USING COMPOSITE FIELDS
ABSTRACT
The faults that accidently or maliciously occur in the hardware implementations of the Advanced Encryption Standard (AES) may cause erroneous encrypted/decrypted output. The use of appropriate fault detection schemes for the AES makes it robust to internal defects and fault attacks.
In this paper, we present a lightweight concurrent fault detection scheme for the AES. In the proposed approach, the composite field S-box and inverse S-box are divided into blocks and the predicted parities of these blocks are obtained.
Through exhaustive searches among all available composite fields, we have found the optimum solutions for the least overhead parity-based fault detection structures. Moreover, through our error injection simulations for one S-box (respectively inverse S-box), we show that the total error coverage of almost 100% for 16 S-boxes (respectively inverse S-boxes) can be achieved.
Finally, it is shown that both the application-specific integrated circuit and field-programmable gate-array implementations of the fault detection structures using the obtained optimum composite fields, have better hardware and time complexities compared to their counterparts.

IMPLEMENTATION AND PERFORMANCE ANALYSIS OF SEAL ENCRYPTION ON FPGA, GPU AND MULTI-CORE PROCESSORS
ABSTRACT
Accelerators, such as field programmable gate arrays (FPGAs) and graphics processing units (GPUs), are special purpose processors designed to speed up compute-intensive sections of applications. FPGAs are highly customizable, while GPUs provide massive parallel execution resources and high memory bandwidth.
In this paper, we compare the performance of these architectures, presenting a performance study of SEAL, a fast, software-oriented encryption algorithm on a Virtex-6 FPGA, a Graphics Processor Unit (GPU), and Intel Core i7, a 2-way hyper-threaded, 4-core processor.
We show that each platform has relative competitive advantages in encrypting an input plaintext using SEAL.

ON THE TRANSMISSION METHOD FOR SHORT RANGE MIMO COMMUNICATIONS
ABSTRACT
This paper investigates a transmission scheme that is suitable for short-range multiple-input-multiple-output (MIMO) transmission. Since the distance between two array antennas that face each other is comparable with the size of the array antenna aperture in short-range MIMO, the propagation characteristics are greatly different from those in conventional MIMO.
Unlike conventional MIMO, the optimal element spacing, which maximizes channel capacity, exists in short-range MIMO. Moreover, the channel capacity with optimal antenna spacing exceeds the ergodic capacity of independent identically distributed (i.i.d.) channels since optimal eigenvalue distribution, which can maximize channel capacity, is obtained in the short-range MIMO.
In this paper, we focus on the actual transmission methods, because complex transmission schemes such as eigenmode transmission or maximum-likelihood detection are required to obtain ideal channel capacity. We clarify that the channel capacity obtained by zero forcing (ZF) at the receiver without beamforming at the transmitter is almost the same as that using eigenmode transmission when considering the optimal element spacing.
The effectiveness of short-range MIMO communication is also clarified using a 4 × 4 MIMO testbed with actual signals based on the IEEE 802.11n standard. Simulated and measured results show that optimal element spacing is a key parameter in the short-range MIMO communication. We found that designing antenna arrays with optimal element spacing is a very effective approach to achieving a simple hardware configuration.

DESIGN AND IMPLEMENTATION OF CORDIC PROCESSOR FOR COMPLEX DPLL
ABSTRACT
Now-a-days various Digital Signal Processing systems are implemented on a platform of programmable signal processors or on application specific VLSI chips. Coordinate Rotation Digital Computer (CORDIC) algorithm has turned out to be such kind of programmable signal processor.
In recent times, it has been a widely researched topic in the field of vector rotated Digital Signal Processing (DSP) applications due to its simplicity. This paper presents the design of pipelined architecture for coordinate rotation algorithm for the computation of loop performance of complex Digital Phase Locked Loop (DPLL) in In-phase and quadrature channel receiver.
The design of CORDIC in the vector rotation mode results in high system throughput due to its pipelined architecture where latency is reduced in each of the pipelined stage.
For on-chip application, the area reduction in proposed design can is achieved through optimization in the number of micro rotations. For better loop performance of first order complex DPLL and to minimize quantization error, the numbers of iterations are also optimized.

DIRECT DIGITAL FREQUENCY SYNTHESIZER USING NONUNIFORM PIECEWISE-LINEAR APPROXIMATION

ABSTRACT
This paper investigates a novel direct digital frequency synthesizer architecture, based on piecewise linear approximation with segments of nonuniform length.
The new approach allows reducing the total number of segments with respect to the well-known uniform segmentation. In this way the size of the coefficient ROM is also reduced with beneficial effects in terms of speed and power.
We show that the optimal nonuniform segmentation (that maximizes the spurious-free dynamic range for a given number of nonuniform segments) can be obtained as the solution of a mixed-integer linear programming problem.
Three simple, suboptimal, nonuniform segmentation schemes (which lend themselves to efficient hardware implementation) are proposed in this paper. We present also several design examples and VLSI implementation results, which demonstrate the effectiveness of the developed technique.

A ROTATION-BASED BIST WITH SELF-FEEDBACK LOGIC TO ACHIEVE COMPLETE FAULT COVERAGE
ABSTRACT
This paper presents a deterministic BIST technique that can efficiently achieve complete fault coverage without using any storage devices. A novel test structure containing a self-feedback logic unit and a circular shift register is proposed by which all the required deterministic patterns can be generated on-chip in real time.
Experiments on ISCAS 85 benchmark circuits show that compared with previous work addressing the same problem our technique requires much less test time to achieve 100% fault coverage for all testable stuck-at faults.

TASK MIGRATION IN MESH NOCS OVER VIRTUAL POINT-TO-POINT CONNECTIONS
Processor allocation in todays many core MPSoCs is a challenging task, especially since the order and requirements of incoming applications are unknown during design stage. To improve network performance, balance the workload across processing cores, or mitigate the effect of hot processing elements in thermal management methodologies, task migration is a method which has attracted much attention in recent years.
Runtime task migration was first proposed in multicomputer with load balancing as the major objective. However, specific NoC properties such as limited amount of communication buffers, more sensitivity to implementation complexity, and tight latency and power consumption constraints bring new challenges in using task migration mechanisms in NoCs.
As a consequence, the efficiency and applicability of traditional migration mechanisms (developed for multicomputers) are under question. Due to the limited resource budget in NoC-based MPSoCs as well as tight performance constraints of running applications, in this paper, we propose an efficient methodology based on virtual point-to-point (VIP for short) connections.
These dedicated VIP connections provide low-latency and low-power paths for heavy communication flows created by task migration mechanisms. Analyzing the results show that the proposed scheme reduces message latency by 13% and migration latency by 14%, while 10% power savings can be achieved compared to the previously proposed task migration strategy (known as Gathering-Rout-Scattering) for mesh multiprocessors.

DYNAMIC CONFLICT-FREE QUERY SCHEDULING FOR WIRELESS SENSOR NETWORKS
Mobile Computing, IEEE Transactions
ABSTRACT
With the emergence of high data rate sensor network applications, there is an increasing demand for high- performance query services in such networks. To meet this challenge, we propose Dynamic Conﬂict-free Query Scheduling (DCQS), a novel scheduling technique for queries in wireless sensor networks.
In contrast to earlier TDMA protocols designed for general-purpose networks and workloads, DCQS is speciﬁcally designed for query services supporting in-network data aggregation. DCQS has several important features.
First, it optimizes the query performance and energy efficiency by exploiting the temporal properties and precedence constraints introduced by data aggregation. Second, it can efficiently adapt to dynamic workloads and rate changes without explicitly reconstructing the transmission schedule.
In addition, we provide an analytical capacity bound for DCQS in terms of query completion rate. This bound enables DCQS to handle overload through rate control.
NS2 simulation results demonstrate that DCQS signiﬁcantly outperforms a representative TDMA protocol (DRAND) and the 802.11 protocol in terms of query latency, throughput, and energy efficiency.

COOPERATING WITH SMARTNESS: USING HETEROGENEOUS SMART ANTENNAS IN MULTI-HOP WIRELESS NETWORKS
Mobile Computing, IEEE Transactions
ABSTRACT
The use of smart antennas in multi-hop wireless networks (MWNs) has garnered significant attention over the last few years. While homogeneous MWNs with all nodes having the same antenna capabilities will have certain applications, we argue that MWNs with nodes having heterogeneous antenna capabilities are more likely to be the norm due to a variety of motivating factors.
In the context of such heterogeneous smart antenna networks (HSANs), we investigate and motivate the need for a simple form of node cooperation called retransmit diversity. We show that while such a simple form of node cooperation cannot bring significant benefits to homogeneous omni-directional antenna networks, they can bring great gains to heterogeneous smart antenna networks.
We then present several key properties pertaining to node cooperation in HSANs along with analytical reasoning. In the process, we identify a fundamental trade-off between exploiting smart antenna gain and cooperation gain, that undermines the ability of HSANs to leverage node cooperation to their maximum potential.
To address this tradeoff, we then present an adaptive cooperation mechanism and incorporate this mechanism through the design of a simple but efficient MAC protocol. The performance of the MAC protocol is evaluated through ns2 simulations along with a realistic physical layer channel model for smart antenna environments.

CACAO: DISTRIBUTED CLIENT-ASSISTED CHANNEL ASSIGNMENT OPTIMIZATION FOR UNCOORDINATED WLANS
Parallel and Distributed Systems, IEEE Transactions on
ABSTRACT
IEEE 802.11 WLANs are becoming more and more popular in homes and urban areas. As compared to traditional WLAN setups (such as in campuses) where knowledgeable network administrators can make centralized decisions on channel selection, access points (APs) in these networks are often deployed by network nonspecialists in an uncoordinated manner, leading to unplanned topologies, interference, and therefore unsatisfactory throughput performance.
We consider in this paper a distributed channel assignment algorithm for uncoordinated WLANs, where APs can self-configure their operating channels to minimize interference with adjacent APs. We first formulate the optimization problem on channel assignment which overcomes some of the weaknesses encountered by uncoordinated WLANs.
We show that the problem is NP-hard, and propose an efficient, simple, and distributed algorithm termed CACAO (Client-Assisted Channel Assignment Optimization). In CACAO, the clients feed back traffic information to their APs.
This leads to better network condition knowledge and better channel assignment decisions at the APs. We conduct extensive simulation study and comparisons using Network Simulator 2 (NS2).
Our results show that CACAO outperforms other traditional and recent schemes in terms of TCP and UDP throughputs with a similar level of fairness. Furthermore, it converges quite fast and reduces cochannel interference significantly.

SCHEDULABILITY ANALYSIS FOR HARD NETWORK LIFETIME WIRELESS SENSOR NETWORKS WITH HIGH ENERGY FIRST CLUSTERING
Reliability, IEEE Transactions
ABSTRACT
Network lifetime predictability is an essential system requirement for the type of wireless sensor network (WSN) used in safety-critical and highly-reliable applications. All sensor nodes in these time-critical WSNs should meet the lifetime constraint at any time instance, else it may cause severe consequences that involve economic losses, or even fatalities.
In the literature, clustering sensors into groups is a popular strategy to maximize the network lifetime, but none of the clustering algorithms address the predictability issue for time-critical WSNs. In this paper, the High Energy First (HEF) clustering algorithm is chosen as a design reference model, which is proved in this paper to be an optimal clustering policy under certain ideal conditions.
To address network lifetime predictability in practice, the network lifetime bounds and feasibility test for the HEF are developed via the worst case energy consumption analysis.
The network simulator 2 (NS2) is used to verify the proposed network lifetime predictability model, and the results show that the derived bounds of the predictability provide accurate estimations of the system lifetime.

TRANSIENT ANALYSIS OF IEEE 802.15.4 SENSOR NETWORKS
Wireless Communications
ABSTRACT
We study the delay performance of a sensor network, whose nodes access the medium by using the unslotted MAC protocol specified by the IEEE 802.15.4 standard.
Unlike previous works, which focus on the average throughput and delay analysis, we develop a detailed model that allows us to obtain the delivery delay distribution of messages sent by concurrently contending sensors toward a central controller.
We carry out a transient analysis that is of particular interest when sensor networks are deployed to provide k-coverage for real-time applications, and we study both single- and multi-hop network topologies. We validate our analytical results against simulation results obtained through ns

SELF-RECONFIGURABLE WIRELESS MESH NETWORKS
Networking, IEEE/ACM Transactions on

ABSTRACT
During their lifetime, multihop wireless mesh networks (WMNs) experience frequent link failures caused by channel interference, dynamic obstacles, and/or applications' bandwidth demands. These failures cause severe performance degradation in WMNs or require expensive manual network management for their real-time recovery.
This paper presents an autonomous network reconfiguration system (ARS) that enables a multiradio WMN to autonomously recover from local link failures to preserve network performance. By using channel and radio diversities in WMNs, ARS generates necessary changes in local radio and channel assignments in order to recover from failures.
Next, based on the thus-generated configuration changes, the system cooperatively reconfigures network settings among local mesh routers. ARS has been implemented and evaluated extensively on our IEEE 802.11-based WMN test-bed as well as through ns2-based simulation.
Our evaluation results show that ARS outperforms existing failure-recovery schemes in improving channel-efficiency by more than 90% and in the ability of meeting the applications' bandwidth demands by an average of 200%.

DYNAMIC CLUSTERING-BASED ADAPTIVE MOBILE GATEWAY MANAGEMENT IN INTEGRATED VANET — 3G HETEROGENEOUS WIRELESS NETWORKS
Communications, IEEE Journal on
ABSTRACT
Coupling the high data rates of IEEE 802.11p-based VANETs and the wide coverage area of 3GPP networks (e.g., UMTS), this paper envisions a VANET-UMTS integrated network architecture. In this architecture, vehicles are dynamically clustered according to different related metrics.
From these clusters, a minimum number of vehicles, equipped with IEEE 802.11p and UTRAN interfaces, are selected as vehicular gateways to link VANET to UMTS. Issues pertaining to gateway selection, gateway advertisement and discovery, service migration between gateways (i.e., when serving gateways lose their optimality) are all addressed and an adaptive mobile gateway management mechanism is proposed.
Simulations are carried out using NS2 to evaluate the performance of the envisioned architecture incorporating the proposed mechanisms. Encouraging results are obtained in terms of high data packet delivery ratios and throughput, reduced control packet overhead, and minimized delay and packet drop rates.

OPTIMAL ROUTE SELECTION METHOD WITH SATELLITE SYSTEM FOR COGNITIVE WIRELESS NETWORK IN DISASTER INFORMATION NETWORK
Networking
ABSTRACT
Cognitive wireless network consisted of multiple different types of wireless interface is one of efficient wireless transmission methods for Disaster Information Network, because it solves single wireless network problems like characteristics of wireless frequency or congestion form the use of same radio frequency.
However, even if Disaster Information Network consisted of Cognitive Wireless Network, some of wireless node might be broken after severe disaster is happened. Therefore, it is necessary to consider about additional functions which the system never die. In this paper, we introduce Satellite System for optimal transmission control method in Cognitive Wireless Network in order to consider with severe disaster.
First, as our previous study, proper wireless link and route selection is held by Extend AHP and Extend AODV with Min-Max AHP value methods for optimal transmission control in Cognitive Wireless Network. Then, check-alive function, alternate data transmission function, possible alternative route suggestion, and network reconfiguration are introduced to our proposed Disaster Information Network by using Satellite System.
In the simulation, ns2 are used for the computational results to the effectiveness of the suggested transmission methods in the hybrid system of cognitive wireless and satellite network system.

INFLUENCE OF ROUTING PROTOCOLS IN PERFORMANCE OF WIRELESS MOBILE ADHOC NETWORK
Information Technology
ABSTRACT
An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. A number of routing protocols such as Dynamic Source Routing (DSR), Ad Hoc on-Demand Distance Vector Routing (AODV) and Destination-Sequenced Distance-Vector (DSDV) have been implemented.
In this paper, an attempt has been made to compare the performance of two prominent on-demand reactive routing protocols for mobile ad hoc networks: DSR and AODV, along with the traditional proactive DSDV protocol. A simulation model with Media Access Control (MAC) and physical layer models are used to study interlayer interactions and their performance implications.
The On-demand protocols, AODV and DSR perform better than table-driven DSDV protocol. Although DSR and AODV share similar on-demand behavior, the differences in the protocol mechanism can lead to measurable amount of variation in performance. A variety of workload are characterized by mobility, load and size of the ad hoc network in a given scenario were simulated which helped to analyze the performance.
The main reason for degradation in performance as a result of node mobility is due to traffic control overhead required for maintaining accurate routing tables in case of table-driven protocols and maintaining routes in on-demand protocols. We quantify the effect of node mobility and message length on the Bit Error Rate (BER) of an average multi-hop route using a recently developed communication-theoretic framework for adhoc wireless network.
We study the network performance such as throughput, delivery ratio, and end-to-end delay when position-based routing is used. Also node mobility and position error affect the performance. The variation in performance differentials are analyzed by use of varying simulation time.
These simulations are carried out using NS-2 simulator. The results presented in this work illustrate the importance in carefully evaluating and implementing routing protocols in an ad hoc environment.

ADAPTIVE, CLUSTER BASED, SENSOR NETWORK ROUTING PROTOCOL
ABSTRACT
In wireless sensor networks, sensor nodes have a limited power resource. The energy consumed to route data from the sensor node to its destination raises as a critical issue in designing wireless sensor network routing protocols.
In this paper we propose a routing protocol called MIN-RC to enhance the hierarchical routing protocol LEACH-C. MIN-RC uses an adaptive method to control the round time considering the current state of the network.
The simulation results of our proposed protocol using the ns2 simulator show that we improve the network efficiency in comparison to existing state-of-the-art protocols.

EFFICIENT TARGET TRACKING THROUGH BINARY-DETECTION IN SPARSELY DEPLOYED WSN
Networking
ABSTRACT
The problem of tracking moving objects with help of wireless sensor network (WSN) has been studied in past. Most of the solutions rely on the use of specialized and expensive sensors, and on dense deployment of sensors. These techniques are infeasible for applications in low budget domains.
In this paper, we propose two novel techniques to track targets using binary sensing that does not need overlapping sensing regions. These techniques can track a target, and estimate the distance it has traversed on the basis of the time that target spends in the vicinity of sensors.
In the first technique, the path traced by a moving target is approximated by tangent estimations to three circles, each representing range of a sensor. It allows us to convert the original problem into a semi definite program.
The other tracking scheme identifies a band of small width where the target is guaranteed to lie. The band is first approximated using the distance travelled after coming out of vicinity of one sensor and before entering the vicinity of second sensor.
This band is then reduced using the distance travelled inside the vicinity of the sensors. We simulated the two methods in NS2 and evaluate both the methods.

AN IMPROVED AODV PROTOCOL WITH LOWER ROUTE COST AND SMALLER DELAY - PWAODV
ABSTRACT
In this paper, an improved AODV - PWAODV (Piggyback and Weighted neighbor stability Ad hoc On-demand Distance Vector routing) protocol with lower route cost and smaller delay is presented.
In the algorithm we introduce a piggyback mechanism and weighted neighbor stability algorithm. Essentially, the route cost can be reduced greatly by the use of piggyback mechanism and the link stability algorithm decreases the delay because of ensuring the robustness of the network topology.
Finally, by comparison in the simulation via NS2, our newly-mentioned protocol could acquire better route cost and delay performances

CHANNEL-AWARE ROUTING IN MANETS WITH ROUTE HANDOFF
Mobile Computing, IEEE Transactions on

ABSTRACT
In wireless mobile ad hoc networks (MANETs), packet transmission is impaired by radio link fluctuations. This paper proposes a novel channel adaptive routing protocol which extends the Ad hoc On-Demand Multipath Distance Vector (AOMDV) routing protocol to accommodate channel fading.
Specifically, the proposed Channel-Aware AOMDV (CA-AOMDV) uses the channel average nonfading duration as a routing metric to select stable links for path discovery, and applies a preemptive handoff strategy to maintain reliable connections by exploiting channel state information.
Using the same information, paths can be reused when they become available again, rather than being discarded. We provide new theoretical results for the downtime and lifetime of a live-die-live multiple path system, as well as detailed theoretical expressions for common network performance measures, providing useful insights into the differences in performance between CA-AOMDV and AOMDV.
Simulation and theoretical results show that CA-AOMDV has greatly improved network performance over AOMDV.

GNDA: DETECTING GOOD NEIGHBOR NODES IN ADHOC ROUTING PROTOCOL
ABSTRACT
With the popularization of Internet and formation of wireless technologies provide significant impact on Internet and Communication Technologies. These technologies have support of one of famous technique known as Adhoc Network. Adhoc Networks are assortment of mobile nodes connected by wireless links and also receiving attention in the scientific community.
In adhoc networks, routes may be disconnected due to dynamic movement of nodes. So, route selection and topology combination is very difficult and challenging issue.
Such networks are more vulnerable to both internal and external attacks due to presence of bad neighbor nodes. Observed problem affects performance of routing protocol in adhoc networks.
In this paper, impact of bad neighbor nodes in adhoc routing is briefly discussed and proposed a method (GNDA) for identifying good neighbor nodes in the network. Besides, this approach is extended by adding extra parameters i.e. signal strength, flow capacity and relative position of a node in to the account.
Proposed method optimizes the routing issues by using AODV. The result of this paper is an appropriate solution against neighbor attacks.

AN ALGORITHM FOR INTELLIGIBILITY PREDICTION OF TIME-FREQUENCY WEIGHTED NOISY SPEECH
Audio, Speech, and Language Processing, IEEE Transactions on
ABSTRACT
In the development process of noise-reduction algorithms, an objective machine-driven intelligibility measure which shows high correlation with speech intelligibility is of great interest. Besides reducing time and costs compared to real listening experiments, an objective intelligibility measure could also help provide answers on how to improve the intelligibility of noisy unprocessed speech.
In this paper, a short-time objective intelligibility measure (STOI) is presented, which shows high correlation with the intelligibility of noisy and time–frequency weighted noisy speech (e.g., resulting from noise reduction) of three different listening experiments.
In general, STOI showed better correlation with speech intelligibility compared to five other reference objective intelligibility models. In contrast to other conventional intelligibility models which tend to rely on global statistics across entire sentences, STOI is based on shorter time segments (386 ms).
Experiments indeed show that it is beneficial to take segment lengths of this order into account. In addition, a free Matlab implementation is provided.

ADAPTIVE MULTISCALE COMPLEXITY ANALYSIS OF FETAL HEART RATE
Biomedical Engineering, IEEE Transactions on
ABSTRACT
Per partum fetal asphyxia is a major cause of neonatal morbidity and mortality. Fetal heart rate monitoring plays an important role in early detection of acidosis, an indicator for asphyxia.
This problem is addressed in this paper by introducing a novel complexity analysis of fetal heart rate data, based on producing a collection of piecewise linear approximations of varying dimensions from which a measure of complexity is extracted.
This procedure specifically accounts for the highly non-stationary context of labor by being adaptive and multiscale. Using a reference dataset, made of real per partum fetal heart rate data, collected in situ and carefully constituted by obstetricians, the behavior of the proposed approach is analyzed and illustrated.
Its performance is evaluated in terms of the rate of correct acidosis detection versus the rate of false detection, as well as how early the detection is made. Computational cost is also discussed. The results are shown to be extremely promising and further potential uses of the tool are discussed

TISSUE-SPECIFIC COMPARTMENTAL ANALYSIS FOR DYNAMIC CONTRAST-ENHANCED MR IMAGING OF COMPLEX TUMORS
Medical Imaging, IEEE Transactions on
ABSTRACT
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) provides a noninvasive method for evaluating tumor vasculature patterns based on contrast accumulation and washout. However, due to limited imaging resolution and tumor tissue heterogeneity, tracer concentrations at many pixels often represent a mixture of more than one distinct compartment.
This pixel-wise partial volume effect (PVE) would have profound impact on the accuracy of pharmacokinetics studies using existing compartmental modeling (CM) methods. We therefore propose a convex analysis of mixtures (CAM) algorithm to explicitly mitigate PVE by expressing the kinetics in each pixel as a nonnegative combination of underlying compartments and subsequently identifying pure volume pixels at the corners of the clustered pixel time series scatter plot simplex.
The algorithm is supported theoretically by a well-grounded mathematical framework and practically by plug-in noise filtering and normalization preprocessing. We demonstrate the principle and feasibility of the CAM-CM approach on realistic synthetic data involving two functional tissue compartments, and compare the accuracy of parameter estimates obtained with and without PVE elimination using CAM or other relevant techniques.
Experimental results show that CAM-CM achieves a significant improvement in the accuracy of kinetic parameter estimation.
We apply the algorithm to real DCE-MRI breast cancer data and observe improved pharmacokinetics parameter estimation, separating tumor tissue into regions with differential tracer kinetics on a pixel-by-pixel basis and revealing biologically plausible tumor tissue heterogeneity patterns.
This method combines the advantages of multivariate clustering, convex geometry analysis, and compartmental modeling approaches. The open-source MATLAB software of CAM-CM is publicly available from the Web.

CELLULAR NEURAL NETWORKS, NAVIER-STOKES EQUATION AND MICROARRAY IMAGE RECONSTRUCTION
Image Processing, IEEE Transactions on
ABSTRACT
Despite the latest improvements in the microarray technology, many developments are needed particularly in the image processing stage. Some hardware implementations of microarray image processing have been proposed and proved to be a promising alternative to the currently available software systems. However, the main drawback is the unsuitable addressing of the quantification of the gene spots which depend on many assumptions.
It is our aim in this paper to present a new Image Reconstruction algorithm using Cellular Neural Network, which solves the Navier-Stokes equation. This algorithm offers a robust method to estimate the background signal within the gene spot region.
Quantitative comparisons are carried out, between our approach and some available methods in terms of objective standpoint. It is shown that the proposed algorithm gives highly accurate and realistic measurements in a fully automated manner, and also, in a remarkably efficient time.

MEMORY-EFFICIENT ARCHITECTURE FOR HYSTERESIS THRESHOLDING AND OBJECT FEATURE EXTRACTION
Image Processing, IEEE Transactions on
ABSTRACT
Hysteresis thresholding is a method that offers enhanced object detection. Due to its recursive nature, it is time consuming and requires a lot of memory resources. This makes it avoided in streaming processors with limited memory.
We propose two versions of a memory-efficient and fast architecture for hysteresis thresholding: a high-accuracy pixel-based architecture and a faster block-based one at the expense of some loss in the accuracy. Both designs couple thresholding with connected component analysis and feature extraction in a single pass over the image.
Unlike queue-based techniques, the proposed scheme treats candidate pixels almost as foreground until objects complete; a decision is then made to keep or discard these pixels. This allows processing on the fly, thus avoiding additional passes for handling candidate pixels and extracting object features.
Moreover, labels are reused so only one row of compact labels is buffered. Both architectures are implemented in MATLAB and VHDL. Simulation results on a set of real and synthetic images show that the execution speed can attain an average increase up to 24× for the pixel-based and 52× for the block-based when compared to s

A CLOSED-FORM APPROXIMATION OF THE EXACT UNBIASED INVERSE OF THE ANSCOMBE VARIANCE-STABILIZING TRANSFORMATION
Image Processing, IEEE Transactions on

ABSTRACT
We presented an exact unbiased inverse of the Anscombe variance-stabilizing transformation and showed that when applied to Poisson image denoising, the combination of variance stabilization and state-of-the-art Gaussian denoising algorithms is competitive with some of the best Poisson denoising algorithms.
We also provided a Matlab implementation of our method, where the exact unbiased inverse transformation appears in non-analytical form. Here we propose a closed-form approximation of the exact unbiased inverse, in order to facilitate the use of this inverse.
The proposed approximation produces results equivalent to those obtained with the accurate (non-analytical) exact unbiased inverse, and thus notably better than one would get with the asymptotically unbiased inverse transformation, which is commonly used in applications.

IMPLEMENTATION OF NEURAL NETWORK CONTROLLED THREE-LEG VSC AND A TRANSFORMER AS THREE-PHASE FOUR-WIRE DSTATCOM
Industry Applications, IEEE Transactions on
ABSTRACT
In this paper, a neural-network (NN)-controlled distribution static compensator (DSTATCOM) using a dSPACE processor is implemented for power quality improvement in a three-phase four-wire distribution system.
A three-leg voltage-source-converter (VSC)-based DSTATCOM with a zig-zag transformer is used for the compensation of reactive power for voltage regulation or for power factor correction along with load balancing, elimination of harmonic currents, and neutral current compensation at the point of common coupling.
The Adaline (adaptive linear element)-based NN is used to implement the control scheme of the VSC. This technique gives similar performance as that of other control techniques, but it is simple to implement and has a fast response and gives nearly zero phase shift.
The zig-zag transformer is used for providing a path to the zero-sequence current in a three-phase four-wire distribution system. This reduces the complexity and also the cost of the DSTATCOM system.
The performance of the proposed DSTATCOM system is validated through simulations using MATLAB software with its Simulink and Power System Blockset toolboxes and hardware implementation.

POSTURE CONTROL OF ELECTROMECHANICAL ACTUATOR-BASED THRUST VECTOR SYSTEM FOR AIRCRAFT ENGINE
Industrial Electronics, IEEE Transactions on
ABSTRACT
This paper deals with the dynamical modeling and posture control of the electromechanical actuator (EMA)-based thrust vector control (TVC) system for aircraft engine. Addressing the issues of the large inertia and low stiffness existed in the TVC system driven by EMA, this paper established a 2-DOF mathematical model to describe EMA dynamic characteristics.
In order to overcome the influence of the motion coupling of the TVC-EMA existed in the pitching and yawing channels, we presented a kind of dual-channel coordinated-control method which realizes the trust vector control for the swung aircraft engine based on the inverse kinematics.
This control strategy uses the command Eulers angles transformation to solve the desired actuator linear lengths, and tracks the desired lengths via the compound control law composed of robust PID with the lead compensation and Bang-Bang control in the two actuators.
The hybrid experimental simulation system based on dSPACE was set up, the control parameters of the compound control methods were confirmed by off-line simulation based on Matlab, and the load experiments of circular motion and step response were implemented on the test system. The simulation and test results show that the designed thrust vector controller can achieve the satisfactory control performances.

MODELING, CONTROL AND MONITORING OF S3RS BASED HYDROGEN COOLING SYSTEM IN THERMAL POWER PLANT
Industrial Electronics, IEEE Transactions on
ABSTRACT
The faster heat dissipation of generators in power plant call for hydrogen cooling, and water is used as coolant to cool down the hot hydrogen which comes out from the hydrogen cooling system (HCS) at generating end. Therefore, in large generating plants the process of cooling and coolant becomes an integral part of the Heat Exchangers. Hence, requirement of a reliable hydrogen cooling system is a must.
This paper presents development and implementation of supervisory control and data acquisition (SCADA) based process control and monitoring system. A novel method of Six Stage Standby Redundant Structured (S3RS) HCS is proposed for the cooling of large generators in thermal power plant(s).
This proposed system is equally reliable for steam turbine based generating plants and Integrated Gasification Combined Cycle (IGCC) plants. The entire process control and monitoring, popularly known as human machine interface (HMI) of HCS has been developed and simulated on RSViewSE, a real-time automation platform by Rockwell Automation. And, the system reliability of the proposed S3RS process model is implemented using MATLAB

POWER LOSS COMPARISON OF SINGLE- AND TWO-STAGE GRID-CONNECTED PHOTOVOLTAIC SYSTEMS
Energy Conversion, IEEE Transactions on
ABSTRACT
This paper presents power loss comparison of single- and two-stage grid-connected photovoltaic (PV) systems based on the loss factors of double line-frequency voltage ripple (DLFVR), fast irradiance variation + DLFVR, fast dc load variation + DLFVR, limited operating voltage range + DLFVR, and overall loss factor combination.
These loss factors will result in power deviation from the maximum power points. In this paper, both single-stage and two-stage grid-connected PV systems are considered. All of the effects on a two-stage system are insignificant due to an additional maximum power point tracker, but the tracker will reduce the system efficiency typically about 2.5%.
The power loss caused by these loss factors in a single-stage grid-connected PV system is also around 2.5%; that is, a single-stage system has the merits of saving components and reducing cost, and does not penalize overall system efficiency under certain operating voltage ranges. Simulation results with the MATLAB software package and experimental results have confirmed the analysis.

SIMPLE ANALYTICAL METHOD FOR DETERMINING PARAMETERS OF DISCHARGING BATTERIES
Energy Conversion, IEEE Transactions on
ABSTRACT
This paper derives simple and explicit formulas for computing the parameters of Thevenin's equivalent circuit model for a discharging battery. The general Thevenin's equivalent circuit model has $n$ pairs of parallel resistors and capacitors (nth-order model).
The main idea behind the new method is to transform the problem of solving a system of high-order polynomial equations into one of solving several linear equations and a single-variable $n$th-order polynomial equation, via some change of variables. The computation can be implemented with a simple MATLAB code less than half-page long.
Experimental and computational results are obtained for three types of batteries: Li-polymer, lead--acid, and nickel metal hydride. For all the tested batteries, the first-order models are not able to generate voltage responses that closely match the measured responses, while second-order models can generate well-matched responses. For some of the batteries, a third-order model can do a better job matching the voltage responses.

BOOSTING COLOR FEATURE SELECTION FOR COLOR FACE RECOGNITION
Image Processing, IEEE Transactions on

ABSTRACT
This paper introduces the new color face recognition (FR) method that makes effective use of boosting learning as color-component feature selection framework. The proposed boosting color-component feature selection framework is designed for finding the best set of color-component features from various color spaces (or models), aiming to achieve the best FR performance for a given FR task.
In addition, to facilitate the complementary effect of the selected color-component features for the purpose of color FR, they are combined using the proposed weighted feature fusion scheme.
The effectiveness of our color FR method has been successfully evaluated on the following five public face databases (DBs): CMU-PIE, Color FERET, XM2VTSDB, SCface, and FRGC 2.0.
Experimental results show that the results of the proposed method are impressively better than the results of other state-of-the-art color FR methods over different FR challenges including highly uncontrolled illumination, moderate pose variation, and small resolution face images.

AUTOMATIC EXACT HISTOGRAM SPECIFICATION FOR CONTRAST ENHANCEMENT AND VISUAL SYSTEM BASED QUANTITATIVE EVALUATION
Image Processing, IEEE Transactions on

ABSTRACT
Histogram equalization, which aims at information maximization, is widely used in different ways to perform contrast enhancement in images. In this paper, an automatic exact histogram specification technique is proposed and used for global and local contrast enhancement of images.
The desired histogram is obtained by first subjecting the image histogram to a modification process and then by maximizing a measure that represents increase in information and decrease in ambiguity. A new method of measuring image contrast based upon local band-limited approach and center-surround retinal receptive field model is also devised in this paper.
This method works at multiple scales (frequency bands) and combines the contrast measures obtained at different scales using Lp-norm. In comparison to a few existing methods, the effectiveness of the proposed automatic exact histogram specification technique in enhancing contrasts of images is demonstrated through qualitative analysis and the proposed image contrast measure based quantitative analysis.

HIGH DYNAMIC RANGE IMAGE DISPLAY WITH HALO AND CLIPPING PREVENTION
Image Processing, IEEE Transactions on

ABSTRACT
The dynamic range of an image is defined as the ratio between the highest and the lowest luminance level. In a high dynamic range (HDR) image, this value exceeds the capabilities of conventional display devices; as a consequence, dedicated visualization techniques are required.
In particular, it is possible to process an HDR image in order to reduce its dynamic range without producing a significant change in the visual sensation experienced by the observer. In this paper, we propose a dynamic range reduction algorithm that produces high-quality results with a low computational cost and a limited number of parameters.
The algorithm belongs to the category of methods based upon the Retinex theory of vision and was specifically designed in order to prevent the formation of common artifacts, such as halos around the sharp edges and clipping of the highlights, that often affect methods of this kind.
After a detailed analysis of the state of the art, we shall describe the method and compare the results and performance with those of two techniques recently proposed in the literature and one commercial software.

GRADIENT PROFILE PRIOR AND ITS APPLICATIONS IN IMAGE SUPER-RESOLUTION AND ENHANCEMENT
Image Processing, IEEE Transactions on

ABSTRACT
In this paper, we propose a novel generic image prior-gradient profile prior, which implies the prior knowledge of natural image gradients. In this prior, the image gradients are represented by gradient profiles, which are 1-D profiles of gradient magnitudes perpendicular to image structures.
We model the gradient profiles by a parametric gradient profile model. Using this model, the prior knowledge of the gradient profiles are learned from a large collection of natural images, which are called gradient profile prior.
Based on this prior, we propose a gradient field transformation to constrain the gradient fields of the high resolution image and the enhanced image when performing single image super-resolution and sharpness enhancement. With this simple but very effective approach, we are able to produce state-of-the-art results.
The reconstructed high resolution images or the enhanced images are sharp while have rare ringing or jaggy artifacts

EXPLORING DUPLICATED REGIONS IN NATURAL IMAGES
Image Processing, IEEE Transactions on

ABSTRACT
Duplication of image regions is a common method for manipulating original images, using typical software like Adobe Photoshop, 3DS MAX, etc. In this study, we propose a duplication detection approach that can adopt two robust features based on discrete wavelet transform (DWT) and kernel principal component analysis (KPCA). Both schemes provide excellent representations of the image data for robust block matching.
Multiresolution wavelet coefficients and KPCA-based projected vectors corresponding to image-blocks are arranged into a matrix for lexicographic sorting. Sorted blocks are used for making a list of similar point-pairs and for computing their offset frequencies. Duplicated regions are then segmented by an automatic technique that refines the list of corresponding point-pairs and eliminates the minimum offset-frequency threshold parameter in the usual detection method.
A new technique that extends the basic algorithm for detecting Flip and Rotation types of forgeries is also proposed. This method uses global geometric transformation and the labeling technique to indentify the mentioned forgeries.
Experiments with a good number of natural images show very promising results, when compared with the conventional PCA-based approach. A quantitative analysis indicate that the wavelet-based feature outperforms PCA- or KPCA-based features in terms of average precision and recall in the noiseless, or uncompressed domain, while KPCA-based feature obtains excellent performance in the additive noise and lossy JPEG compression environments.

AUTOMATIC ROAD EXTRACTION USING HIGH RESOLUTION SATELLITE IMAGES BASED ON LEVEL SET AND MEAN SHIFT METHODS
ABSTRACT
Analysis of high resolution satellite images has been an important research topic for urban analysis. One of the important features of urban areas in urban analysis is the automatic road network extraction. Two approaches for road extraction based on Level Set and Mean Shift methods are proposed.
From an original image it is difficult and computationally expensive to extract roads due to presences of other road-like features with straight edges. The image is preprocessed to improve the tolerance by reducing the noise (the buildings, parking lots, vegetation regions and other open spaces) and roads are first extracted as elongated regions, non-linear noise segments are removed using a median filter (based on the fact that road networks constitute large number of small linear structures).
Then road extraction is performed using Level Set and Mean Shift method. Finally the accuracy for the road extracted images is evaluated based on quality measures. The 1m resolution IKONOS data has been used for the experiment

PERFORMANCE ANALYSIS OF INTEGER WAVELET TRANSFORM FOR IMAGE COMPRESSION
ABSTRACT
For image compression, it is very necessary that the selection of transform should reduce the size of the resultant data as compared to the original data set .In this paper, a new lossless image compression method is proposed.
For continuous and discrete time cases, wavelet transform and wavelet packet transform has emerged as popular techniques. While integer wavelet using the lifting scheme significantly reduces the computation time, we propose a completely new approach for further speeding up the computation.
First, wavelet packet transform (WPT) and lifting scheme (LS) are described. Then an application of the LS to WPT is presented which leads to the generation of integer wavelet packet transform (IWPT).
The proposed method, Integer Wavelet Packet Transform (IWPT) yields a representation which can be lossless, as it maps an integer valued sequence onto the integer valued coefficients. The idea of Wavelet Packet Tree is used to transform the still and color images.
IWPT tree can be built by iterating the single wavelet decomposition step on both the low-pass and high-pass branches, with rounding off in order to achieve the integer transforms. Thus, the proposed method provides good compression ratio.

TRACKING AND COUNTING PEOPLE IN VISUAL SURVEILLANCE SYSTEMS
ABSTRACT
The greatest challenge on monitoring characters from a monocular video scene is to track targets under occlusion conditions. In this work, we present a scheme to automatically track and count people in a surveillance system.
First, a dynamic background subtraction module is employed to model light variation and then to determine pedestrian objects from a static scene. To identify foreground objects as characters, positions and sizes of foreground regions are treated as decision features.
Moreover, the performance to track individuals is improved by using the modified overlap tracker, which investigates the centroid distance between neighboring objects to help on target tracking in occlusion states of merging and splitting.
On the experiments of tracking and counting people in three video sequences, the results exhibit that the proposed scheme can improve the averaged detection ratio about 10% as compared to the conventional work.

A VIEW ON LATEST AUDIO STEGANOGRAPHY TECHNIQUES
ABSTRACT
Steganography has been proposed as a new alternative technique to enforce data security. Lately, novel and versatile audio steganographic methods have been proposed.
A perfect audio Steganographic technique aim at embedding data in an imperceptible, robust and secure way and then extracting it by authorized people. Hence, up to date the main challenge in digital audio steganography is to obtain robust high capacity steganographic systems.
Leaning towards designing a system that ensures high capacity or robustness and security of embedded data has led to great diversity in the existing steganographic techniques.
In this paper, we present a current state of art literature in digital audio steganographic techniques. We explore their potentials and limitations to ensure secure communication. A comparison and an evaluation for the reviewed techniques is also presented in this paper.

DETECTING BACKGROUND SETTING FOR DYNAMIC SCENE
ABSTRACT
Processing Real-Time image sequence is now possible because of advancement of technological developments in digital signal processing, wide-band communication, and high-performance VLSI.
With the developments in video technology, the surveillance system can be built with some low cost gadget such as the web-camera. In this modern life with increasing number of crime rate, people in society need for security and safety; video surveillance has become important reason to oppose threats of crime and terrorism.
The most fundamental part of surveillance is foreground detection, which is retrieval of an object of interest. The object of interest can remodel by common background subtraction technique. There is some problem arises by using this technique, where because of variation of light source, the background constantly changes.
The intensity of pixel changes throughout the object detection takes place. Intensity of pixel value changes leads to improper foreground detection, the background detected as foreground object.
This paper proposes a method to model and update the background of the scene by intersection solving method.

This system features double DSP architecture so it can transmit and process image very fast. It is small, light, low power consumption and low cost. It is easy for single taking and operation, so has good application prospect in field reconnaissance, traffic surveillance, city layout and the situation of bad weather or a disaster and so on.

AN IMPROVED MEDIAN FILTERING ALGORITHM COMBINED WITH AVERAGE FILTERING
ABSTRACT
To solve the contradiction between the noise-reducing effect and the time complexity of the standard median filter algorithm, the paper proposed an improved median filter algorithm combined with average filtering.
According to the correlation of the image, the algorithm adaptively resizes the filter mask according to noise levels of the mask. According to the sorting results of the selected pixel values in the neighborhood, the algorithm uses the median to replace the original pixel.
Experimental results show that the improved algorithm can effectively reduce time complexity and has better noise-reducing effect than the standard median filter algorithm. It has a good application prospect in image processing.

REMOVAL OF HIGH DENSITY SALT AND PEPPER NOISE THROUGH MODIFIED DECISION BASED UNSYMMETRIC TRIMMED MEDIAN FILTER
ABSTRACT
A modified decision based unsymmetrical trimmed median filter algorithm for the restoration of gray scale, and color images that are highly corrupted by salt and pepper noise is proposed in this paper.
The proposed algorithm replaces the noisy pixel by trimmed median value when other pixel values, 0's and 255's are present in the selected window and when all the pixel values are 0's and 255's then the noise pixel is replaced by mean value of all the elements present in the selected window.
This proposed algorithm shows better results than the Standard Median Filter (MF), Decision Based Algorithm (DBA), Modified Decision Based Algorithm (MDBA), and Progressive Switched Median Filter (PSMF).
The proposed algorithm is tested against different grayscale and color images and it gives better Peak Signal-to-Noise Ratio (PSNR) and Image Enhancement Factor (IEF).

A NEW ADAPTIVE WEIGHT ALGORITHM FOR SALT AND PEPPER NOISE REMOVAL
ABSTRACT
A new adaptive weight algorithm is developed for the removal of salt and pepper noise. It consists of two major steps, first to detect noise pixels according to the correlations between image pixels, then use different methods based on the various noise levels.
For the low noise level, neighborhood signal pixels mean method is adopted to remove the noise, and for the high noise level, an adaptive weight algorithm is used.
Experiments show the proposed algorithm has advantages over regularizing methods in terms of both edge preservation and noise removal, even for heavily contaminated image with noise level as high as 90%, it still can get a significant performance.

A MODIFIED WEIGHTED BASED FILTER FOR REMOVAL OF RANDOM IMPULSE NOISE (MWB)
ABSTRACT
In this paper an effort has been made to device an algorithm for highly corrupted images. In this paper a novel Modified Weighted Based(MWB) filter has been proposed, which is based on the weighted differences between the current pixel and its neighbors aligned with four main directions.
Simulations showed that the MWB filter provides optimal performances of suppressing impulse with high noise level which may enhance the performance in terms of removal of random-valued impulse noise compared to the directional weighted median (DWM) filter along with other filters like signal-dependent rank order mean (SDROM)filter, multistate median (MSM) filter, adaptive center weighted median (ACWM) filter, pixel-wise MAD(PWMAD) filter etc.

RANDOM IMPULSE NOISE REMOVAL FROM IMAGE SEQUENCES BASED ON FUZZY LOGIC
ABSTRACT
In this paper a new filter for image sequences corrupted with random impulse noise is presented. In order to preserve the image details as much as possible, the noise is removed in different successive filtering steps. In each step, only the pixels that are detected as being noisy are filtered, while the noise-free pixels remain unchanged.
The noise detection is based on fuzzy set theory and fuzzy rules, which are very useful for the processing of human knowledge and linguistic values. To exploit the temporal information in image sequences as much as possible, detected pixels are finally filtered in a motion compensated way.
From the experimental results it can be seen that the proposed method outperforms other state-of-the-art filters both in terms of the peak-signal-to-noise ratio, the mean absolute error, and visually.

POISSON NOISE REMOVAL FROM IMAGES USING THE FAST DISCRETE CURVELET TRANSFORM
ABSTRACT
We propose a strategy to combine the variance stabilizing transform (VST), used for Poisson image denoising, with the fast discrete Curvelet transform (FDCT). The VST transforms the Poisson image to approximately Gaussian distributed, and the subsequent denoising can be performed in the Gaussian domain. However, the performance of the VST degrades when the original image intensity is very low.
On the other hand, the FDCT can sparsely represent the intrinsic features of images having discontinuities along smooth curves. Therefore, it is suitable for denoising applications. Combining the VST with the FDCT leads to good Poisson image denoising algorithms, even for low intensity images.
We present a simple approach to achieve this and demonstrate some simulation results. The results show that the VST combined with the FDCT is a promising candidate for Poisson denoising.

MDS-BASED MULTIRESOLUTION NONLINEAR DIMENSIONALITY REDUCTION MODEL FOR COLOR IMAGE SEGMENTATION
ABSTRACT
In this paper, we present an efficient coarse-to-fine multiresolution framework for multidimensional scaling and demonstrate its performance on a large-scale nonlinear dimensionality reduction and embedding problem in a texture feature extraction step for the unsupervised image segmentation problem.
We demonstrate both the efficiency of our multiresolution algorithm and its real interest to learn a nonlinear low-dimensional representation of the texture feature set of an image which can then subsequently be exploited in a simple clustering-based segmentation algorithm.
The resulting segmentation procedure has been successfully applied on the Berkeley image database, demonstrating its efficiency compared to the best existing state-of-the-art segmentation methods recently proposed in the literature.

DISCRETE WAVELET TRANSFORM-BASED SATELLITE IMAGE RESOLUTION ENHANCEMENT
ABSTRACT
Satellite images are being used in many fields of research. One of the major issues of these types of images is their resolution. In this paper, we propose a new satellite image resolution enhancement technique based on the interpolation of the high-frequency subbands obtained by discrete wavelet transform (DWT) and the input image.
The proposed resolution enhancement technique uses DWT to decompose the input image into different subbands. Then, the high-frequency subband images and the input low-resolution image have been interpolated, followed by combining all these images to generate a new resolution-enhanced image by using inverse DWT.
In order to achieve a sharper image, an intermediate stage for estimating the high-frequency subbands has been proposed. The proposed technique has been tested on satellite benchmark images.
The quantitative (peak signal-to-noise ratio and root mean square error) and visual results show the superiority of the proposed technique over the conventional and state-of-art image resolution enhancement techniques.

WAVELET ENHANCED FUSION ALGORITHM FOR MULTISENSOR IMAGES

ABSTRACT
Due to the limitation of the image acquisition equipment itself and the constraints of taking environment and other factors, the resolution and contrast of the obtained images have declined, and some important information in the images was hidden in the acquisition process.
Therefore, in order to get a richer picture, the source images must be enhanced prior to the integration, so as to access the hidden information. The proposed paper introduces the general integration scheme based on image enhancement, and presents a fusion method with the wavelet image enhancement technology.
We first enhance the source images according to wavelet image enhancement technology, and then use the appropriate fusion rule to integrate the coefficients of the original images and the enhanced images.
Experimental results show that the enhancement of the source images prior to integration, could improve the fusion effect and obtain the hidden information barely acquired through directly fusion without enhancement.

A STEGANOGRAPHIC METHOD BASED ON INTEGER WAVELET TRANSFORM AND GENETIC ALGORITHM

ABSTRACT
This paper proposes a novel steganography scheme based on Integer Wavelet Transform and Genetic Algorithm. The novel scheme embeds data in integer wavelet transform coefficients by using a mapping function based on Genetic Algorithm in an 8 × 8 block on the cover image.
The optimal pixel adjustment process is applied after embedding the message. We employed frequency domain to increase the robustness of our steganography method. Integer wavelet transform avoids the floating point precision problems of the wavelet filter.
We use GA and Optimal Pixel Adjustment Process to obtain an optimal mapping function to reduce the difference error between the cover and the stego-image and to increase the hiding capacity with low distortions respectively.
Simulation results show that the novel scheme outperforms adaptive steganography technique based on integer wavelet transform in term of peak signal to noise ratio and capacity, 35.17 dB and 50% respectively.

SECURITY ANALYSIS ON SPATIAL 1 STEGANOGRAPHY FOR JPEG DECOMPRESSED IMAGES

ABSTRACT
Although many existing steganalysis works have shown that the spatial ±1 steganography on JPEG pre-compressed images is relatively easier to be detected compared with that on the never-compressed images, most experimental results seem not very convincing since these methods usually assume that the quantization table of the JPEG stegos previously used is known before detection and/or the length of embedded message is fixed.
Furthermore, there are just few effective quantitative algorithms for further estimating the spatial modifications. In this letter, we firstly propose an effective method to detect the quantization table from the contaminated digital images which are originally stored as JPEG format based on our recently developed work about JPEG compression error analysis, and then we present a quantitative method to reliably estimate the length of spatial modifications in those gray-scale JPEG stegos by using data fitting technology.
The extensive experimental results show that our estimators are very effective, and the order of magnitude of prediction error can remain around measured by the mean absolute difference.
