Noise and variability are fundamental companions to ion channels and synapses and thus inescapable elements of brain function. The overriding unresolved issue is to what extent noise distorts and limits signaling on one hand and at the same time constitutes a crucial and fundamental enrichment that allows and facilitates complex adaptive behavior in an unpredictable world. Here we review the gr...

In this paper, we investigate various aspects of the polysilicon gate influence on the random dopant induced threshold voltage fluctuations in sub-100 nm MOSFET’s with ultrathin gate oxides. The study is done by using an efficient statistical three-dimensional (3-D) “atomistic” simulation technique described elsewhere [1]. MOSFET’s with uniform channel doping and with low doped epitaxial channe...

Arc furnaces can be classified as electricity receivers, which largely affect the quality of in power system. Voltage fluctuations are main disturbance generated by arc furnaces. The effects voltage include phenomenon flickering light. Apart from fluctuations, devices, to a lesser extent, source current and asymmetry, curve distortion, dips. purpose theoretical considerations is assess article ...

– We consider arrays of Josephson junctions as well as single junctions in both the classical and quantum-mechanical regimes, and examine the generalized (frequency-dependent) resistance, which describes the dynamic responses of such Josephson-junction systems to external currents. It is shown that the generalized resistance and the power spectrum of voltage fluctuations are related via the flu...

The hybrid AC-DC microgrid (HMG) architecture has the merits of both DC and AC coupled structures. Microgrids are subject to intermittence when the renewable sources are used. In the HMG, since power fluctuations occur on both subgrids due to varying load and unpredictable power generation from renewable sources, proper voltage and frequency regulation is the critical issue. This article propos...

With the expansion of introduction of renewable energy sources (RES) such as photovoltaics (PV), voltage fluctuations (fluctuated voltage by PV output ups and downs depending on sunshine changing) in distribution network can be increasing. As a method of suppressing voltage fluctuations, intensive control of voltage control equipment by the introduction of a centralized voltage control system (...
