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

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.


^ FAULT LOCATION IN UNDERGROUND POWER NETWORKS: A CASE STUDY

This paper appears in: Innovative Smart Grid Technologies (ISGT), 2011 IEEE PES

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


^ 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.

^ 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


^ MOTION COMPENSATION WITH ONE-AXIS GYROSCOPE AND TWO-AXIS ACCELEROMETER FOR AUTOMOTIVE SAR

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.

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.

The fabricated system has been used for field trials and very satisfactory results are obtained.


^ 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.


^ DESIGN AND IMPLEMENTATION FOR AMBULANCE ROUTE SEARCH BASED ON THE INTERNET OF THINGS

ABSTRACT

The internet of things (IoT) is a network to realize interconnects between almost any object and web services. It can be applied in many domains, such as radio frequency identification (RFID), wireless sensor network(WSN) and so on. The application of IoT brings us the higher efficiency and the more convenient life.

In this paper, we propose a new IoT application framework to search the optimal routes for the ambulances with taking into account the effects for the traffic in the ambulance running time. 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.

ABSTRACT

In order to solve the problems of the communication among various metering devices in the traditional wireless meter reading system, Smart Message Language (SML) which is the definition of the German national standard for Automatic Meter Reading System is introduced.

^ 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.

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 τ 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 ΔT 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 ΔT. 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.

^ SYSTEM LEVEL DESIGN OF A SECURE HEALTHCARE SMART CARD SYSTEM

ABSTRACT

Smart card-based healthcare system has several advantages over conventional paper-based systems in terms of security, privacy and portability. In this study, a secure health care smart card system was designed and simulated.

The goal of the project is to design a smart card system which will meet the major requirements of a healthcare identity system. Main features of the proposed system are data storage and secure data transfer. The system is a heterogeneous system with hardware and software components and it was designed using electronic system-level design methodology (ESL) with a top-down approach.

It consists of cryptographic primitives, a central processing unit and memory blocks. RSA and AES are used for key share and encryption, respectively. An LFSR is employed to generate pseudo-random numbers which are used for calculating keys. We have used Aldec Active-HDL Student Edition to develop the system and perform mixed-language simulations. We have functionally verified the system using Active-HDL.


^ 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.

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.

^ 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.

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.
