This paper deals with the control of voltage and frequency of a wind turbine driven isolated asynchronous generator. The controller consists of an IGBT (Insulated Gate Bipolar Junction Transistor) based 3-leg voltage source converter and a battery at its DC link. The controller is having bidirectional flow capability of active and reactive powers by which it controls the system voltage and freq...

introduction: bipolar spectrum disorders include a variety of mood disorders from bipolar ii disorder to conditions characterized by hyperthymic mood states. it has been suggested that psychosocial factors also play an important role in bipolar disorders, in this study we have used social network analysis in order to better understand the social positions of those affected by bipolar spectrum d...

Inspired by an electromagnetic hydropower station that contains a reverse polarized magnet, we proposed new design methodology of electret rotatory energy harvester (e-REH) with bipolar-charged electrets for boosting its output performance. A selectively localized corona discharging method is invented to have both positive and negative ultra-high-resolution charges implanted into single thin fi...

This paper deals with a integrated Electronic Load Controller (IELC) for an isolated asynchronous generator (IAG), used in constant power pico hydro power generation for feeding three-phase four-wire loads. The proposed IELC is used to control the voltage and frequency of IAG in the integrated manner. This IELC is realised using a T-connected transformer and three-leg insulated gate bipolar tra...

BACKGROUND Overall and left temporal scalp area reductions of P300 have been demonstrated in schizophrenia. P300 amplitude and topography in psychotic affective disorder, a crucial comparison in assessing the specificity of P300 abnormalities to schizophrenia, are not well studied. METHODS P300 was recorded from 35 schizophrenic, 20 psychotic manic, and 30 control subjects. All were right-han...
