many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...

The paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. Some mathematical vector models were obtained for control system multicriterion quality indices with due ...

In this paper, an extension of the power half-normal (PHN) distribution is introduced. This new model built on application slash methodology for positive random variables. The result a with greater kurtosis than PHN; i.e., its right tail heavier PHN distribution. Its probability density, survival and hazard rate function are studied, moments, skewness coefficientes obtained, along relevant prop...
