This paper describes the modelling and the analysis of control logic for a Nano-Device- based PWM controller.A comprehensive simple SPICE schematic model for Single Electron transistor has been proposed.The operation of basic Single Electron colts dog collar Transistor logic gates and SET flip flops were successfully designed and their performances
Hypersonic aircraft represent an important area of aerospace development.Raising the aircraft lift-to-drag ratio, improving the efficiency of attitude control, and optimizing aerodynamic performance are important goals.Active flow control technology can improve the aerodynamic performance of the aircraft while optimizing its control attitude.In the
Potential evapotranspiration (PET) is an importance process in water balance studies controlled by a number of meteorological factors such as temperature, wind speed, atmospheric pressure, solar radiation, vapor pressure gradient, relative humidity and biological factors such as vegetation type, canopy height and plant density that varied in time-s
