Breast cancer is a common disease with unknown reason. So, early detection or prediction is better way to fight against this disease. A method can be used to detect mass in mammograms and predict breast cancer in its early ...

Design of a fractal antenna structure based on iteration 1 and iteration 2 of hexaflake fractal structure is proposed. A multiport network model of basic hexagonal patch structure is analysed. Based on hexagonal structure ...

AC voltage converters are widely used as one of the power electronics systems to control an output ac voltage, where a variable ac voltage is obtained from a fixed ac voltage, for power ranges from few watts up to fraction ...

In this research a new method is proposed for tracing the individual contribution from each generator to each line’s flow, each line’s loss and each load which is very much essential for billing the individual entities ...

Two new topologies of single-phase Buck-Boost AC-DC converters with low input current THD and high input power factor are proposed and presented. Instead of using a single phase rectifier followed by a boost dc-dc ...

An accurate model to simulate drain current versus gate voltage characteristics is developed for double gate MOSFET and a drain current model is proposed for double gate uniaxially strained silicon MOSFET. The model can ...

Optical wireless, also known as free-space optics (FSO), has become very popular in recent years as a cost-effective, license-free communication technique for high-rate ‘last-mile’ terrestrial communications [1]. However, ...

Bangladesh has joined the submarine cable consortium in the 4th September 2002. However, the deployment of submarine cable connectivity alone would not ensure provisions for different e-services, such as data, voice, video, ...

The goal of this thesis is to obtain a simple and easily implementable scheme for input power factor correction and harmonic reduction in a three phase rectifier. A basic three phase diode rectifier having specified ...
