The paper presents a novel secondary reactance control technique in the rotor circuit of a three phase wound rotor induction motor (WRIM). The problem associated with the conventional rotor capacitive reactance control is the demand of exceptionally large capacitance requirement for enhancing the performance of the motor in wide operating range. In the proposed technique, a three phase bridge r...

BACKGROUND Impulse oscillometry (IOS) is a non-demanding lung function test. Its diagnostic use may be particularly useful in patients of advanced age with physical or mental limitations unable to perform spirometry. Only few reference equations are available for Caucasians, none of them covering the old age. Here, we provide reference equations up to advanced age and compare them with currentl...

Knowledge of patient fluid distribution would be useful clinically. Both single-frequency (SF) and impedance modeling approaches are proposed. The high intercorrelation between body water compartments makes determining the best approach difficult. This study was conducted to evaluate the merits of an SF approach. Mathematical simulation was performed to determine the effect of tissue change on ...

Psychological reactance theory posits that when people are faced with threats to, or elimination of, behavioral freedom, they experience an aversive motivational state (i.e., psychological reactance). Recent research indicates people’s of mind affects arousal processes. We hypothesized being in a threatening uncertainty would cause to less freedom-threatening communication than those certainty....

OBJECTIVES Non-compliance with neuroleptic medication in schizophrenia is a major cause of relapse. A number of sociodemographic variables, and illness, attitudinal and treatment variables, have been demonstrated to be associated with non-compliance. The present study examined a range of these variables and their predictive value in determining past and current compliance. METHODS Thirty-nine...

This paper presents a new method of substantially improving frequency pullability and linearity using reactance in series with an AT fundamental crystal operated with a series load capacitance in the range of 3 to 50 pF and frequencies in the range of 3.5 to 21 MHz. The research describes high quartz pullability and linearity by varying the load capacitance. The paper also gives impedance circu...

This paper presents a systematic procedure for modelling and simulation of a power system installed with a power system stabilizer (PSS) and a flexible ac transmission system (FACTS)-based controller. For the design purpose, the model of example power system which is a single-machine infinite-bus power system installed with the proposed controllers is developed in MATLAB/SIMULINK. In the develo...
