The actual market volume of high-power lasers for manufacturing is dominated by diffusion cooled CO2 laser systems at the multi-kW range and lamp pumped Nd:YAG laser systems at the kW range. Substituting the lamps by diodes the Nd:YAG laser in rod design entered the market as diode pumped solid state laser of the first generation. With output powers up to 6 kW the diode pumped rod is used in in...
the renewable energy sources and plug-in electric vehicles (pevs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. this paper presents modelling and control of a building integrated fuel cell and plug-in electric vehicles (bifc-pev) in smart distribution systems. in bifc-pev system, conventional building elements could be replaced by sp...
Nowadays high-voltage power sources is used in different areas such as generation of atmospheric-pressure plasma. Different voltage waveforms affect the plasma generation and its quality. In this paper a new high voltage square wave with DC-offset power source is presented to study the different parameters on plasma generation and propagation. The proposed converter which is based on power semi...
Entangled photon spectroscopy is a nascent field that has important implications for measurement and imaging across chemical, biology, materials fields. potentially offers improved spatial temporal-frequency resolutions, increased cross sections multiphoton nonlinear measurements, new abilities in inducing or measuring quantum correlations. A critical step enabling entangled spectroscopies the ...
The expansion of Islamic awaking waves in the middle-east has managed to substantially influence the sources of soft power of global powers and the US and great regional powers such as Iran. This study tries to analyze the impacts of recent public-religiousuprisings on the change of soft power sources of Iran and the US. The findings of this study suggest that regarding the nature and purposes ...
course contents of b.sc. and even m.sc. or ph.d. programs in electrical power engineering in our country is mainly based on conventional; technologies employed in different sectors of generation, transmission and distribution of electricity. electricity industry in iran has been successful in localization and transfer of technology from foreign countries and research centers and universities ha...
scaling challenges and limitations of conventional silicon transistors have led the designers to apply novel nano-technologies. one of the most promising and possible nano-technologies is cnt (carbon nanotube) based transistors. cnfet have emerged as the more practicable and promising alternative device compared to the other nanotechnologies. this technology has higher efficiency compared to t...
