Electric and hybrid electric vehicles are attractive candidates for sustainable transportation due to its higher efficiency and low emission. The critical choice on the electric motors is its capability of motoring and regenerative braking characteristics. Switched reluctance machines are viable candidate as with proper control and extended constant power range operation replacing the multi-gea...
Supply development is a major challenge in electric power industry. In order to fulfill this need, and regarding complexities in the energy sector, a comprehensive model such as system dynamics is zimperative. The purpose of this study is to reach this model. The performance of the model was based on the selection of a technology which could give way to the lowest total cost of genera...
The electric field in cavity accelerates charged particles and magnetic field of magnets changes the direction of these particles in cyclotrons. In order to establish the electric field inside the cavity, a noiseless radio frequency (RF) signal should be generated, amplified and sent to cavity. The resonant frequency of the cavity could be changed by temperature variation. Variation of resonant...
Three-phase induction motors are widely used in electric traction systems. Impacts of the traction vehicle equipped by three-phase induction motors on power quality are much different from the impacts of vehicles with DC traction motors. In this paper, the effects of the traction vehicle operation with threephase induction motors on power quality in 110 kV transmission network are investigated....

Heterodyne light scattering is employed to probe the electrophoretic flow behavior of a concentrated, deionized model colloidal suspension. Both for the fluid and crystalline regime, the power spectra are well described as velocity distributions, which let assume that the power spectra are dominated by the self-dynamic structure factor. Furthermore, all measured power spectra show an increase o...
