the purpose of this research was to identify sources of management power in physical education organization managers and to determine its relationship to employees' readiness and satisfaction with their supervisors. the method of this research was descriptive correlational. the statistical population consisted of all employees of physical education organization. a random sample of 118 empl...
Low power efficiency is one of the main problems THz sources, colloquially known as gap. In this work we present prototypes devices based on whisker-crystals a hightemperature superconductor Bi2Sr2CaCu2O8+d with record high radiation 12% at frequency 4 THz. We employ various on- and off-chip detection techniques and, in particular, use radiative cooling phenomenon for accurate evaluation emissi...
this paper presents a control strategy developed for optimizing the power flow in a fuel cell hybrid vehicle structure. this method implements an on-line power management based on the optimal fuzzy controller between dual power sources that consist of a battery bank and a fuel cell (fc). the power management strategy in the hybrid control structure is crucial for balancing between efficiency an...
In conventional power systems, frequency and voltage deviations are chosen as indexes for characterizing conventional power system security. While in an autonomous micro grid with Electronically Interfaced Distributed Generation (EIDG), frequency and voltage deviations against power and loads disturbances perfectly controlled by f-P and V-Q controller. Unlike conventional power syst...
