This paper presents a parametric low differential order model, suitable for mathematically analysis for Induction Machines with faulty stator. An adaptive Kalman filter is proposed for recursively estimating the states and parameters of continuous–time model with discrete measurements for fault detection ends. Typical motor faults as interturn short circuit and increased winding resistance ...

Several field-oriented induction motor drive methods without rotational transducers have been proposed. These methods have a disadvantage that the rotor resistance variation causes an estimation error of the motor speed. Therefore, simultaneous estimation of the motor speed and the rotor resistance is required. This paper presents a method of estimating simultaneously the motor speed and the ro...

This paper proposes a modified dynamic equivalent circuit model for linear induction motor considering both longitudinal end effect and transverse edge effect. The (speed-dependent effect) is based on conventional Duncan’s approach. investigated by using three correction factors applied to the secondary resistance magnetizing inductance. Moreover, iron saturation effect, skin air-gap leakage ar...

Background: Visfatin is an adipokine secreted from visceral adipose tissue and involved in glucose homeostasis. The aim of the present study was to investigate the effect of eight-week resistance training on plasma visfatin levels and its relation to insulin resistance in insulin-resistant male rats. Methods: In this experimental study twenty-four Wistar male rats­ (220±20 gr) were acclimati...

Single-phase squirrel cage and three-phase induction electromotors are the most popular electromotors used in industry from long ago. When an induction motor starts with direct connection method, it takes a lot of current from the power supply (several times the nominal current); so, several methods have been devised to start such electromotors. These methods either reduce the voltage of the st...

Cytochrome P450 enzymes metabolize various endogenous and exogenous small molecular weight compounds. Transport-associated proteins, such as P-glycoprotein, multidrug resistance-associated protein and lung resistance protein are overexpressed in drug-resistant cell lines, as well as in human tumors from various histologic origins, including malignant melanoma. Little is known about the expressi...
