The s t u 4 investigates the variation of both the single-event induced current and the consequent collected charge with bias, substrate doping and minority carrier lifetime. We show that the minority carrier lifetime is the key factor in determining the amount of the total collected charge. We suggest that the reduction of the minority carrier lifetime in the substrate renders the device more immune against single events.","PeriodicalId":180043,"journal":{"name":"International Conference on Electrical, Electronic and Computer Engineering, 2004.

The circuit demultiplexes the input clock signal into thirteen phased output signals by streaming sets of twenty-six clock phases. A phase difference equal to the half period of the clock is maintained between consecutive output transitions. The VHDL description of the PDMUX13 cell is given and the simulation and synthesis results are generated. A 2-level tree-like structure is built by applying the phased outputs of the PDMUX13 cell into the corresponding clock inputs of thirteen cell replicas that extend the circuit behavior. The EXOR13 gate is attached to the PDMUX13 cell output ports and is aggregating all the phases that the phased clock signals are carrying while preserving their phase associations.","PeriodicalId":180043,"journal":{"name":"International Conference on Electrical, Electronic and Computer Engineering, 2004.

In such techniques the source nodes can estimate the network state and make the routing decision locally, hence reducing the signaling traffic at core routers and other network elements. However, using only locally collected information to make routing decision is not a completely reliable technique to achieve trusted QoS performance. The Localized Multi-Path Selection (LMPS) approach is proposed in this paper to overcome the common drawbacks of the localized techniques. The LMPS technique is a multi-path selection algorithm, which selects paths that are capable of satisfying the bandwidth requirement of the call, while at the same time trying to avoid the overloaded links to minimize the overall blocking ratio in the network.","PeriodicalId":180043,"journal":{"name":"International Conference on Electrical, Electronic and Computer Engineering, 2004.

The detection of low-level ground-currents using any conventional over-current or ground fault type relays is both difficult and sometimes inaccurate. [ 1-71. The Arc-nature of all (HIF) faults, being intermittent in nature, characterized by very low level fault current is also rich in low harmonic content and high frequency noise spectra that identify and fingerprint any existence of Arc hazardous HIF faults. High Impedance Arc-Type faults are safety hazard to Humans, Live stocks and Electric Utility Personnel. If left undetected for hours, weeks, and possibly months can prove fatal to humans and animals at typical current level of 50 milliampere or above. The need to find a simple, fast and accurate detection scheme using only time domain substation voltage and current signals (few cycles) at the feeder is the motivation for this novel Pattendshape Based Recognition and Identification approach. Other techniques by the first author [8-101 encompass Neutral Residual harmonics, excursion harmonic-vector, frequency-based nonlinear transformations, Artificial Neural Network and this new concept of the Harmonic PattemsPhase Portraits (HPP-Concept) introduced in this paper.

Decision fusion may be pursued to combine the outputs of dflerent classifiers applied on the same data, in the hope of combining the best of what each approach provides.

The method is based on decoupled control of instantaneous active and reactive power components, where the corresponding reference ac line currents are obtained using two PI-controllers loops. One PI controller is for the active power loop and the other is for the reactive power component. This scheme can be considered as simplified direct power control valid for both three-phase and single-phase PWM rectifiers. Both dynamic and steady state performance are studied. According to the obtained results, the control scheme offers several advantages such as: control of dc side voltage, fast dynamic performance, and sinusoidal ac line currents. Moreover, the proposed scheme does not require high sampling rates which was the major drawback of conventional direct power control strategy.","PeriodicalId":180043,"journal":{"name":"International Conference on Electrical, Electronic and Computer Engineering, 2004.

Our system, known as GenShade, evaluates evolutionarily generated procedural textures by comparing their rendered images with single or multiple target images of a desired texture. It uses a multiresolution image querying metric to automatically prioritize parents for breeding. GenShade uses a novel approach to the genetic algorithm problem, mimicking several key factors in natural selection. It employs a multiple generation breeding population, a notion of gender, and the concept of aging to maintain diversity while providing many breeding opportunities to highly successful offspring. The approach is also especially efficient running in a multiple processor, multiple selectionstrategy mode.
