Photovoltaic systems normally use a maximum power point tracking (MPPT) technique to continuously deliver the highest possible power to the load when variations in the isolation and temperature occur, Photovoltaic (PV) generation is becoming increasingly important as a renewable source since it offers many advantages such as incurring no fuel costs, not being polluting, requiring little mainten...

extended interaction oscillators (eio) are vacuum electronic sources of microwave, millimeter-wave and terahertz radiations. in this paper, eio is investigated by using a circuit model. the value of the coupling element in the model is evaluated from the near band-edge dispersion characteristics of the rf structure. the end external loading of the interaction structure is equivalently modeled b...

voltages and currents are induced into electronic circuit boards as electromagnetic waves are radiated on them. the strength of induction depends on the wavefront and the circuit board characteristics. in this paper, by solving maxwell’s equations using fdtd method and then by extending it by three dimensional simulation using the gpml criteria for boundary conditions and tf/sf technique, effec...

This chip uses both biological motivation and compact focal-plane processing to solve a real commercial problem such as 2D camera pointing [1]. This system is unique in its use of a spatially variant layout and arbitration between smooth pursuit (in fovea) and acquisition (in periphery) to improve the tracking process (similar to primate visual tracking). Furthermore, with the exception of the ...

In modern and crowded traffic life, it becomes mandatory to save the human life by reaching the hospital very sooner than possible. This paper explains about the advancement in tracking the ambulance presence amidst the traffic with the usage of GPS tracking system calculating the position of the ambulance from the traffic signal which replaces the RF transmitter receiver circuitry. This paper ...

The increasing interests in using renewable energies are coming from solar thermal energy and solar photovoltaic systems to the micro production of electricity. Usually we already have considered the solar tracking topology in large scale applications like power plants and satellite but most of small scale applications don’t have any solar tracker system, mainly because of its high cost and com...
