This paper presents a neural network-based motion detector system of an object. The system consists of two components: a preprocessing and data compression part and a decision making subsystem that provides information about the motion of an object. A neural network is used as a decision making subsystem. The network is trained with a general object motion and tested on a specific unseen motion by the network. The training and testing errors were used to judge the performance of the network. The result is promising and shows the potential application of neural network to design a motion detection system.<>

This paper presents both experimental results and calculations of CFO voltages for 115 kV and 230 kV substations. Several different methods are used to calculate the CFO voltage. The accuracy of specific equations and a graphical method used for the evaluation of CFO voltages for HV substations are discussed. The paper concludes with a discussion and analysis of equations used for the estimation of air clearances in HV substations based on CFO voltages.<>

Today's mobile professionals must not only stay connected any time, anywhere and with anybody, but they must have the ability to communicate many types of information anywhere and with anybody. The accelerating trend in information appliances for people on the go is setting new standards. The latest advances in computer and communication technologies has made possible an entirely new breed of hand-held communications/information appliance. This article describes the communicator, and discusses the technical challenges of integrating a fully functional computer with an RF transmitter/receiver, modem, fax, etc. into the IBM Personal Communicator.<>

This paper describes methods for verifying and testing very large scale integrated (VLSI) electronic devices and subsystems according to an architecture specification. With these methods, the specification serves as the database which drives the verification and testing of the device through all phases of development: simulation, functional testing, and characterization. A hierarchical method of organization for an architecture specification is shown, verified, used to generate test cases for simulation and testing on a VLSI test system. Finally, methods for generating test programs and characterization tests are described. The unifying theme of these methods is that an architectural specification can be used to generate all phases of development.<>

The multi-valley transport model using the displaced Maxwellian distribution (DMD) is applied to study hot-electron transport phenomena in a two-valley semiconductor in fast transient situations. It is shown that the DMD approach at high fields is inadequate. The velocity overshoot behavior given by this approach is less pronounced than the Monte Carlo results. Also, the DMD leads to relatively small mean energy and large average velocity at high fields.<>

The convergence properties of linearly stable multi-dimensional systems are investigated for the case of delta-operator implementations in fixed-point format. It is shown that zero-convergence is almost never achieved, if the sampling time is small. Using a one-dimensional analysis, it is demonstrated that zero-convergence cannot be guaranteed along the axis of the first hyper-quadrant for a first hyper-quadrant causal system. This limits the use of delta-operators for solving partial differential equations in discrete time with fixed-point arithmetic.<>

This paper proposes a novel PWM converter which is a modified version of the conventional boost topology with output electrical isolation and zero-voltage switching (ZVS). The steady-state analysis and the control characteristic curves are presented. Also, the authors present a closed loop system for the converter as a power factor correction circuit (PFCC) application. The system uses voltage referencing and current sensing. This is achieved by implementing the commercially available chip ML4821 (average current mode controller) in the closed loop system. Circuit simulation based on PSPICE of the proposed topology is given. It is shown that the simulation and theoretical results are in agreement.<>

Virtual reality (VR) has been applied in developing systems for vehicle simulation, robot control, decision support and analysis, virtual interfaces to complex systems, entertainment, electronic art, medical science, and education. As an off-spin of virtual reality, a number of sensory hardware components have been developed. One of the greatest potentials of VR exists in medicine and surgery. The author discusses some of the sensory devices developed for VR systems, and then suggests an application in evaluating the performance of impaired hand. The proposed system can be used to monitor patient's progress in therapy and to devise better treatment strategies. The author finally concludes with a discussion on some of the challenges and issues facing the existing technology.<>

This paper presents the results of an investigation of the lightning performance of a transmission line with spline ball ionizers. An experimental investigation was conducted to determine the critical flashover (CFO) voltage between a scale model of a charged cloud and a transmission line with spline ball ionizers. The CFO voltages for the standard lightning impulses were measured for both positive and negative polarity.<>
