In today's world, the development of electromagnetic devices require the magnetic cores to be operated at higher frequency. Soft magnetic composite (SMC) materials are suitable for these applications because of their properties like high electrical resistivity which leads to the low eddy current loss, and 3-D magnetic isotropy which provides great design(More)
Self organizing genetic algorithm (SOGA) is a class of heuristic multi-objective optimization method that has high capabilities for solving multiple conflicting objective functions. This paper presents an application of SOGA for optimizing multi-objectives components placement of multi voltage regulator (MVR) system on printed circuit board by considering(More)
Advancement of electronic technology has led to increase heat dissipation of the component, especially in Central Processing Unit (CPU). This problem occurs when the component has scaled down to increase the power density and the speed of data processing. This heat dissipation has increased the temperature of the device, which can reduce the reliability and(More)
Sensors play a very important role in all kind of industrial plant. Types of sensor can vary from level, flow, pressure and temperature. In an industrial plant, a huge quantity of sensors are being installed for monitoring purpose. These sensors involve complex installation architecture due to cable and installation cost. Each and every single sensor only(More)
