a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
Living near high-voltage power lines and exposure to high-frequency electromagnetic fields (EMFs) is a potential serious hazard to animal and human health. The present study was carried out to evaluate the effect of high-frequency EMFs from simulated high-voltage electric towers on cognitive, anatomical, and biological changes in male Macaque. In this study, two Rhesus Macaque were recruited, ...
in this paper, an attempt has been made to introduce a new control strategy including plug-in hybrid electric vehicle (phev) and diesel engine generator to control the voltage and frequency of autonomous microgrids. the proposed control strategy has multiple advantages over the recent control methods in microgrids. the proposed method applies the primary and secondary frequency control strategy...

Electromagnons, which are coupled polar and magnetic excitations in magnetoelectric materials, of large interest for electronic computing technological devices. Using molecular dynamics simulations based on an ab initio effective Hamiltonian, we predict that the frequency several electromagnons can be tuned by application electric fields model multiferroic ${\mathrm{BiFeO}}_{3}$, with this eith...
This paper aims to find the efficient state of hybrid electric vehicle (HEV) by simultaneous optimization of the control strategy and the power train. The power transmission employed in this vehicle is a power-split continuously variable transmission (CVT) which uses several fixed ratio mechanisms. After describing this transmission, the rules of electric assist control strategy are introduced....
