For events that produce massive numbers of casualties, the system is overwhelmed and many victims whose lives possibly could have been salvaged in a multiple-casualty situation will succumb to their injuries/illnesses as ...

The main feature of the Fast-Field Cycling (FFC) Nuclear Magnetic Resonance (NMR) power supplies is to drive a controlled current fulfilling the requirements of this technique. This feature allows fast switching the current of the FFC magnet and performing accurate and repetitive current cycles. When designing this equipment the power losses is not a fundamental parameter of the optimization pr...

Recently, power quality (PQ) has because a significant issue for both power supplies and customers. Researchers in all developed countries know that power quality is one of the factors of losses in the network. Increasing power electronic equipment changes current waveform in distribution networks and this can cause many problems in networks. Distortion of voltage waveforms results in the appea...
