Power quality testing is important to wind power applications for several reasons. The nature of wind turbine generation is different from conventional power plants. Although windfarms are growing in capacity and diversifying in nature in the U.S. and throughout the globe, there is no standard that addresses the power quality of wind turbines or wind farms. The International Electrotechnical Co...

Modern society critically depends on the services electric power provides. Power systems rely on a network of power lines and transformers to deliver power from sources of power (generators) to the consumers (loads). However, when power lines fail (for example, through lightning or natural disasters) or when the system is heavily used, the network is often unable to fulfill all of the demand fo...

fue to the importance of selecting imaging parameters in magnetic resonance brain angiography, this study was carried out to choose optimum theoretical and experimental parameters for improving image controast and resolution and achieve shorter imaging time for practical reasons.a 1.5t super conductive magnet mri with gradient power of 13 nt/m and larmour frequency of 63 mhz with imaging coli o...

The authors have studied a new method to find parameters of broadband power line communication channel model. Lossless power line communication channel model is compared with classical interferometers approach to develop this model. The authors also used coaxial cables to simulate a multipath channel, because it can behave like a lossless power line communication channel. Thus, measurements wer...

The transmission of electricity from the source to load is mainly carried out using a three-phase line [...]

AlxwaciThis contribution introduces instrumental speech quality measures for the GSM system based only on transmission parameters. Certain combinations of CSM parameters which quantify the transmission quality in terms of bit error rate, received power level, etc., were shown be suitable for the prediction of the resulting speech quality. Neither the original nor the received speech signal is n...
