microhole electrical discharge machining (EDM) system with daptive fuzzy logic control and precision piezoelectric stage is eveloped in this study. A high-speed EDM monitoring system is mplemented to measure the gap voltage, current, and ignition elay time, which are used to derive three input parameters—the verage gap voltage, deviation in spark ratio, and change in the eviation in spark ratio...

This paper presents design and torque analysis in various types of magnetic gear with different magnetic materials and air gap. This type of gear offer both high speed and high torque required for drive applications. In the proposed gear analysis the low speed side is connected to prime mover and high speed side is connected to load, suitable for wind power, automobile applications and group dr...

The education gap between men and women has closed, or has even reversed in many countries. Have countries also made progress in closing other gaps facing women? Using micro-level Census data for close to 40 countries, we examine several dimensions of gender disparity: we compare men and women’s labor force participation (the labor force participation gap), married and single women’s labor forc...

In this paper, an analytical method based on Modified Slab Method of analysis is presented to study the asymmetrical rolling process due to difference in work rolls radii, rolls speeds and interface frictions. The shear force imposed on material along the contact region is considered to be a function of the frictional factor and the roll gap geometry. Elastic-plastic with linear work hardening ...
