the aim of this study was to investigate the relationship between leadership style and power source of coaches in iranian super league volleyball teams from players’ point of view as well as to prioritize leadership styles and power sources in coaches of all teams. for this purpose, all iranian super league volleyball team players in season 2008-2009 completed the leadership scale for sport (ch...
In this paper a multi-variable LPV/H∞ control approach is applied to design a strategy for power source coordination within a multi-source energy system. Three different kinds of power sources – fuel cell, battery and ultracapacitor – compose the power supply system of an electric vehicle. All sources are current-controlled and paralleled together with their associated DC-DC converters on a com...
The need for high power apparatus in industry has increased in recent years. Multilevel inverters have developed as easy alternatives for such power requirements. Multilevel inverters consist of a group of semiconductor switches and a set of voltage source components like capacitors or independent sources. The basic concept of these inverters depends on using this series of switches and sources...
This paper study the recent seismicity in Earthquake hazard zones in India. A large historical earthquake event catalog to cover the period of 1900-2018, the parameters date, time, latitude, longitude, depth and magnitude has been used to calculating frequency-magnitude distribution (b-value) of seismic hazard zones in India. To convert different magnitude scales into a single moment magnitude ...
Mid-infrared laser sources are of great interest for various applications, including light detection and ranging, spectroscopy, communication, trace-gas detection, and medical sensing. Silicon photonics is a promising platform that enables these applications to be integrated on a single chip with low cost and compact size. Silicon-based high-power lasers have been demonstrated at 1.55 μm wavele...
The annals of history are replete challenges over which feelings have been widely ambivalent. Beyond any shadow of doubt clean and reasonable power production based on environmental problems and lack of fossil fuel sources is one of them. This essay takes an in-depth look at the result of an output simulation of a multi sources hybrid power system includes Wind, PV and Diesel generators to show...
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...
Microturbine generation system is one of the most promising and a fast growing distributed generation sources. It is used in various applications thanks to high efficiency, quick start and high reliability. Combination of the microturbine and storage system (e.g. battery bank) is desirable selection to satisfy the load requirements under all conditions and hence the battery bank can play an imp...
