We report on two microfluidic elastomeric autoregulatory devices-a diode and a rectifier. They exhibit physically interesting and complex nonlinear behaviors (saturation, bias-dependent resistance, and rectification) with a Newtonian fluid. Due to their autoregulatory properties, they operate without active external control. As a result, they enable increased microfluidic device density and ove...

Space vector control is popular for controlling motor drives or three-phase rectifiers since it offers reduced switching losses and better utilization of the DC bus compared to conventional PWM modulation. This report describes a space vector controller for a three-phase boost-type rectifier that is implemented in PLECS. The schematic diagram of the boost rectifier is shown in Fig. 1. The sourc...

Rectified Linear Units (ReLUs) have been shown to ameliorate the vanishing gradient problem, allow for efficient back-propagation, and empirically promote sparsity in the learned parameters. Their use has led to state-of-the-art results in a variety of applications. In this paper, we characterize the expressiveness of ReLU networks. From this perspective, unlike the sign (threshold) and sigmoid...

Deep neural network acoustic models produce substantial gains in large vocabulary continuous speech recognition systems. Emerging work with rectified linear (ReL) hidden units demonstrates additional gains in final system performance relative to more commonly used sigmoidal nonlinearities. In this work, we explore the use of deep rectifier networks as acoustic models for the 300 hour Switchboar...

Design considerations and performance evaluations of a three-phase, four-switch, single-stage, isolated zero-voltage-switching (ZVS) rectifier are presented. The circuit is obtained by integrating the three-phase, two-switch, ZVS, discontinuous-current-mode (DCM), boost power-factorcorrection (PFC) rectifier, named for short the TAIPEI rectifier, with the ZVS full-bridge (FB) phase-shift dc/dc ...

In order to achieve the transformation of electrical energy in Variable Speed Constant Frequency (VSCF) Wind Power Generation System (WPGS), a novel Space Vector Pulse Width Modulation (SVPWM) pulse trigger technology applied in high efficient PWM rectifier is proposed. Rectifier is an important part of WPGS and its performance affects the harmonic content and power factor of the power energy d...

The membrane models of (Cannon et al. [l] and Alberink et al. [2 ] for mammaliain skeletal muscle fibers are based upon Hodgkin-Huxley descriptions of sodium, potassium delayed rectifier and leak conductance’s and the capacitive current taking into account fast inactivation of sodium channels. Now inward rectifier and chloride ion currents, sodiumpotassium oump and slow inactivation of sodium c...

In nucleus basalis neurons, substance P (SP) causes a slow excitation, mediated through a pertussis toxin-insensitive G protein, by suppressing an inward rectifier K+ channel. Here we report that SP applied outside the patch pipette inhibited the single-channel activity, recorded on-cell, of the inward rectifier. The PKC inhibitors staurosporine and PKC(19-36) suppressed this effect in whole-ce...

Active heat flow control is essential for broad applications of heating, cooling, and energy conversion. Like electronic devices developed for the control of electric power, it is very desirable to develop advanced all-thermal solid-state devices that actively control heat flow without consuming other forms of energy. Here we demonstrate temperature-gated thermal rectification using vanadium di...

A bridgeless PFC rectifier allows the current to flow through a minimum number of switching devices compared to the conventional PFC rectifier. Accordingly, the converter conduction losses can be significantly reduced and higher efficiency can be obtained, as well as cost savings. The comparative study is done between the bridgeless buck and Cuk converter. Hence the harmonics are reduced to obt...
