VOLT-AMPERE CHARACTERISTIC AND INDUCED CURRENT IN THE EXTERNAL CIRCUIT OF AVALANCHE-GENERATOR DIODES ON THE BASIS OF THE BACK DISPLACED ABRUPT P–N-JUNCTIONS [PDF]

open access: yesРадиофизика и электроника, 2015
Creation of modern solid-state microwave power sources is based on the application of active elements with expanded functionality. The reverse-biased p–n-junctions with DC voltage are active elements of diodes generators. Avalanche-generator diodes (AGD)

Weakening Assumptions for Deterministic Subexponential Time Non-Singular Matrix Completion [PDF]

open access: yes, 2009
In (Kabanets, Impagliazzo, 2004) it is shown how to decide the circuit polynomial identity testing problem (CPIT) in deterministic subexponential time, assuming hardness of some explicit multilinear polynomial family for arithmetical circuits.

A simplified mathematical theory of MHD power generators

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
We present a simplified version of the Faraday magnetohydrodynamics (MHD) generators theory. The effect of the Loretz force against the fluid ow is neglected, whence it follows the uniform ow of the plasma. We use Lazăr Dragoș’s analytic solution for the

State Estimation-Based Hybrid-Triggered Controller Design for Synchronization of Repeated Scalar Nonlinear Complex Dynamical Networks

open access: yesIEEE Access, 2023
The goal of this work is to examine the issue of state estimation-based synchronization of nonlinear complex dynamical networks that are prone to external disturbances, repeated scalar nonlinearities and time-varying coupling delays.

Inductance in Neural Systems [PDF]

open access: yes, 2018
Abstract:A neural circuit model involving inductance is established to explain the neural networks’ behavior. A parallel resistor-inductor-capacitor (RLC) circuit was used to fit the stimulus artifacts in the electromyography (EMG) recording of cortical and pelvic electrical nerve stimulations.

The Design and Optimization of a Novel Hybrid Excitation Generator for Vehicles

open access: yesWorld Electric Vehicle Journal
Silicon rectifier generators, which are single-excitation generators, are commonly used in vehicles. However, a traditional single-excitation generator cannot satisfy the requirements of modern vehicles due to its low efficiency, high failure rate and ...
