nowadays with increasing use of numerous nonlinear loads, voltage and current harmonics in power systems are one of the most important problems power engineers encounter. many of these nonlinear loads, because of their dynamic natures, inject time-varying harmonics into power system. common techniques applied for harmonics measurement and assessment such as fft have significant errors in presen...

A recent theory is reviewed for the shot noise of coherent radiation propagating through a random medium. The Fano factor P/Ī (the ratio of the noise power and the mean transmitted current) is related to the scattering matrix of the medium. This is the optical analogue of Büttiker’s formula for electronic shot noise. Scattering by itself has no effect on the Fano factor, which remains equal to ...

For data communication over any medium, it is necessary to determine the characteristics of the communication channel. Powerline channel has been considered as a medium not only for low-rate, control purpose communication, but also for high-speed data communication, such as home networking and Internet access. In order to implement advanced communication technologies, the complete knowledge of ...

Due to a limited battery capacity, an energy efficient architecture is vital for a 3G mobile phone. In this paper the characteristics (in terms of power consumption and quality) of a rake receiver in combination with a turbo decoder are considered. Important parameters are selected and their influences on the energy consumption and quality are investigated by means of simulations.

-The performance of IC interconnects has been stretched tremendously recently years by high speed integrated circuit systems. Even though S-parameters are popularly used for the characterization of IC interconnects, their modeling has to consider the existence of active devices, such as buffers and drivers. The I/O model is difficult to obtain due to the IP protection and limited information. I...

Wind power generation systems influence power quality in a specific way making important the need for detailed and accurate evaluation of disturbances caused by wind generators. Wind power system can cause suband interharmonic components to appear in the spectrum of voltages and currents. The paper shows different aspects of spectrum estimation in power systems, including the doubly fed inducti...
