Power factor performance on 0.35 mm and 0.50 mm thicknesses of steel sheets for 0.5 Hp induction motor using FEM software
(Science and Engineering Publishing Company, 2012-12)
Decrease the thicknesses of steel sheets will increase the power factor of the 0.5 Hp induction motor. This paper presents the effect of thicknesses in power factor for non-oriented electrical steel sheets. The study was ...
Effect of lattice constant on band-gap energy and optimization and stabilization of high-temperature In xGa 1 -xN quantum-dot lasers
(Springer US, 2012-07)
We analyze the effect of the lattice constant on the band-gap energy of In x Ga1−x N and optimize the structure of the device with a separate-confinement heterostructure. To vary the lattice constants, we change the In ...
Comparison study on chebyshev and composite lowpass filter for harmonic rejection in two ways radio
(Malaysian Technical Universities Network (MTUN), 2012-11-20)
The paper is on a comparison study on Chebyshev and Composite lowpass filter designed at 300-400 MHz used for harmonic rejection in two ways radio. The filter is used to attenuate harmonic that generated by power amplifier ...
Performance improvement of spectral amplitude coding-optical code division multiple access systems using NAND detection with enhanced double weight code
(The Optical Society of Japan, 2012-01)
The bit-error rate (BER) performance of the spectral amplitude coding-optical code division multiple access (SACOCDMA) system has been investigated by using NAND subtraction detection technique with enhanced double weight ...
In house construction of an induction motor rotor by using 0.35mm thickness of steel sheet for efficiency based investigation
(Trans Tech Publications, 2012)
In this paper, an in house production of a 0.5hp induction motor's rotor is investigated. This investigation considers the induction motor's efficiency and losses dissipation as an important aspect to determine the rotors ...
Reactive power tracing in pool-based power system utilising the hybrid genetic algorithm and least squares support vector machine
(The Institution of Engineering and Technology, 2012-02)
This study presents a new method for reactive power tracing in a pool-based power system by introducing the hybrid genetic algorithm and least squares support vector machine (GA-LSSVM). The idea is to use GA to obtain the ...
A comparison on PSO variants in calculating HEPWM switching angles for a cascaded H-bridge multilevel inverter
(Springer Science+Business Media, LLC, 2012)
This paper presents a comparison study on the application of various PSO algorithms in calculating the Pulse Width Modulation (PWM) switching angles of a cascaded H-bridge multilevel inverter. It aims to investigate the ...
