induction heating is widely used in metal industry for melting or heating thin slabs in a continuous casting plant. the wide application is based on good efficiency, high production rate and non-polluting conditions. for designing a parallel resonant induction heating system, calculating the capacitance for the resonant circuit is important, because its value affects resonance frequency, output...

Based on role enactment theory, leadership task theory, and emerging notions of leadership as a collective process, this study examined the existence and performance correlates of collective team leadership in state department of transportation road maintenance teams. Confirmatory factor analysis (n=277) supported a hypothesized four-factor model consisting of: planning and organizing, problems...

in this paper particle swarm optimization with smart inertia factor (pso-sif) algorithm is proposed to solve combined heat and power economic dispatch (chped) problem. the chped problem is one of the most important problems in power systems and is a challenging non-convex and non-linear optimization problem. the aim of solving chped problem is to determine optimal heat and power of generating u...

in this research using statistical analysis the effect of machining parameters such as cutting velocity, feed rate, and tool type on machining power (p m ) in machining process of en-ac 48000 aluminum alloy has been studied. a taguchi l 27 standard array has been utilized as the most economical array to evaluate the factors and their interaction. en-ac 48000 alloy is frequently used in automoti...

This paper discusses the circuit theory aspects of power factor correction in switching converter circuits. The discussion begins with an examination of the requirement of power factor correction in dc=dc converters. Using the concept of zero-order converter circuits, su cient conditions for a dc=dc converter circuit to provide power factor correction are derived. The duality principle is appli...

In this paper, a simple algorithm based on a two-diode circuit model of the solar cell is proposed for calculating different parameters of PV panels. The input parameters required for this algorithm are available from datasheets of the standard PV modules. The values of series and parallel resistances, as well as the recombination factor of Diode 2, are estimated through an iterative solution p...
