Optimization methods are increasingly used for the design process of electrical machines. The quality optimization result and necessary simulation effort depend on methods, machine models parameters used. This paper presents a multi-stage environment induction It uses strategies simulated annealing, evolution strategy pattern search. Artificial neural networks to reduce solution optimization. s...

A sensorless online temperature estimator is presented in this paper, which estimates the using a novel signal injection strategy. This allows to eliminate sensors machine, as well their faults, increasing system reliability. double dead-time DC injected adding controlled offset control drive through inverter. The proposed strategy eliminates effect of signal, an important drawback strategies f...

This paper presents a non-invasive procedure to detect inter-turn short circuit faults in the stator windings of AC electrical machines. It proposes use stray external magnetic field measured vicinity machine determine faults. The originality introduced by this is analysis method presented paper, which when compared usual diagnosis methods, does not require any data on healthy state machine. us...

objective: this study was conducted with the aim to investigate and compare iranian produced and foreign oxytocin for use in induction of labor. materials and methods: this random clinical trial was conducted on a population of 198 pregnant women with live fetus and cephalic presentation and conditions conducive to induction of labor, monitored by obstetricians and gynecologists. they were rand...
