Research ArticleOpen accessIn the abstractChoice Of Input Data Type Of Artificial Neural Network To Detect Faults In Alternative Current SystemsT. Benslimane, B. Chetate, R. BeguenaneThis paper present a study on different input data types of ANN used to detect faults such as over-voltage in AC systems (AC network , induction motor). The input data of ANN are AC voltage and current. In no fault condition, voltage and current are sinusoidal. The input data of the ANN may be the instantaneous values of voltage and … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 6,779 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModeling and Simulation of a Novel Switched Reluctance Motor Drive System with Power Factor ImprovementG. Venkatesan, R. Arumugam, M. Vasudevan et al.This study presents a novel Switched Reluctance Motor (SRM) drive system with power factor improvement. Recently, many of the converters with variable speed drives have no input power factor correction circuits. This results in harmonic pollution of the utility supply, which should be avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,099 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Whole-body Magnetic Field on Changes of Glucose and Cortisol Hormone in Guinea PigsS. Zare, H. Hayatgeibi, S. Alivandi, A. G. EbadiThe main goal of this study was to evaluate the possible effect of whole-body Magnetic Field (MF) exposure on the variations of glucose and corlisol hormone levels on 36 adult male Guinea pigs in four separate experiments, male Guinea pigs, were exposed to sinusoidal 5Hz, 0.013 μT and 50 Hz-0.207 μT MF. Duration of exposure was 2 and 4 h/day … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 4 · 31 Dec 2005 · 6,272 accessesView PDF Cite
