Switched reluctance motor (SRM) drive has a remarkable characteristic, high efficiency, and good controllability, which makes it attractive for high-speed applications. In this paper, the basic control strategy for a switched reluctance motor drive circuit is explained and then three different resonant discharge topologies for SRM drive circuit are proposed. Due to resonantly discharging of exc...

computation of the second order delay in rc-tree based circuits is important during the design process of modern vlsi systems with respect to having tree structure circuits. calculation of the second and higher order moments is possible in tree based networks. because of the closed form solution, computation speed and the ease of using the performance optimization in vlsi design methods such as...

Millimeter-wave communication uses a frequency of at least 30GHz, which is higher than that commonly used for wireless local-area networks (LANs) and cellular phones. Millimeter waves have been used for business communications and radar in luxury cars; however, their use has not yet spread to the general public. In recent years, an increasing amount of research results on millimeter-wave comple...

This thesis contributes to the computer-aided design (CAD) of spiral inductors and LC resonators with spiral inductors exploiting full-wave electromagnetic (EM) analysis. The spiral inductor is widely used in radio frequency integrated circuits (RF ICs), such as low noise amplifiers (LNA) and voltage controlled oscillators (VCO). The design of spiral inductors has a direct influence on the perf...

Rodent models of absence epilepsy generate spike-and-wave oscillations at relatively fast frequency (5±10 Hz) compared with humans (» 3 Hz). Possible mechanisms for these oscillations were investigated by computational models that included the complex intrinsic ®ring properties of thalamic and cortical neurons, as well as the multiple types of synaptic receptors mediating their interactions. Th...

The aim of this review is to cover recent developments in the mathematical analysis subwavelength resonators. use sophisticated mathematics field metamaterials reported, which provides a framework for focusing, trapping, and guiding waves at scales. Throughout review, power layer potential techniques combined with asymptotic solving challenging wave propagation problems scales demonstrated.
