Diffuse electron-beam ionized discharges break down into arc discharges under three different conditions: static (no discharge orE-beam), dynamic (discharge on) and pulsed (inductive) overvoltage at switch-off. Dynamic breakdown voltages are lower than static breakdown voltages but in normal operation the discharge "on" voltage is kept to a minimum. The maximum load voltage will only be present...

Spin-dependent quantum transport properties in twisted carbon nanotube and stretched carbon nanotube are calculated using density functional theory (DFT) and non-equilibrium green’s function (NEGF) formulation. Twisting and stretching have no effect on spin transport in CNTs at low bias voltages. However, at high bias voltages the effects are significant. Stretching restricts any spin-up curren...

Deep Brain Stimulation or DBS is the second solution for Parkinson's Disease. Its three parameters are: frequency, pulse width and voltage. They must be optimized to achieve successful treatment. Nowadays it is done clinically by neurologists and there is not certain numerical method to detect them. The aim of this research is to introduce simulation and modeling of Parkinson's Disease treatmen...

Design techniques for low-voltage analog TUters In CMOS technologies are discussed. The use of OTA-C implementation techniques towards low power supply voltages (3 V and below) requires special source degeneration and input signal folding techniques. Firstly, design techniques to achieve Pull CMOS continuous-time filters with low distortlon (Total harmonic distortion c -50 dB) and low power sup...

This paper presents a resource-constrained scheduling scheme and a latency-constrained scheduling scheme that minimize power consumption for the case when the resources operate at multiple voltages. The resource-constrained scheduling reduces the power consumption by maximally utilizing resources operating at reduced voltages and, at the same time, reducing the latency. The latency-constrained ...

This paper presents a novel circuit architecture for implementing analog Turbo-style decoders in subthreshold CMOS with low supply voltage. Various analog Turbo decoding circuits have been demonstrated in recent years which require significantly less power and silicon area than digital circuits while providing high throughput. As CMOS process technologies improve, allowable supply voltages are ...

In this paper, we study the unbalance problem of the input Direct Current (DC) voltages of the five-level neutral point clamping (NPC) voltage source inverter (VSI) used in hybrid renewable energy system. The hybrid system is composed of doubly fFed induction generator (DFIG) driven by wind turbine, the rotor is connected to three fivelevel NPC VSI feed by photovoltaic voltage source. We show p...

The inverse problem in 3D eddy current imaging is ill-posed and non-linear. The most commonly used image reconstruction algorithms for electrical imaging are based on a linear approximation (the Jacobian Matrix). We start with an initial conductivity distribution. The forward problem is solved and the predicted voltages compared with the calculated voltages from the Finite Element model. The co...

ABSTRACT The main focus of this paper is to control the active power supplied by distributed generation (DG) system while compensating harmonics and reactive currents caused by the nonlinear loads using shunt active power filter (APF). The APF control is based on load currents sensing for reference current estimation in a-b-c reference frame. In order to get the grid currents sinusoidal and in-...
