Performance improvement of SHWS by increasing thermal efficiency using insulation materials and optimum position of solar collectors
(BRAC University, 2011-12)
The word itself “Solar” describes that we are dealing with some renewable energy source for a hot water system. A Solar Hot Water System (SHWS) has been already designed; further implementation has been done by working on ...
Cognitive radio wireless networks
(BRAC University, 2011-04)
Standards groups and regulatory bodies around the world are increasingly seeking new ways of using, allowing access to, or allocating spectrum. In most parts of the world, cellular network bands are overloaded, but amateur ...
Performance improvement of solar hot water system by reducing solar irradiation from solar collector and solar tank
(BRAC University, 2011-04)
The word itself ―Solar‖ describes that we are dealing with some renewable energy source for a hot water system. The solar hot water system has been a popular throughout the world as it is cost effective and easy to maintain. ...
Develop and test a method to convert wired systems into wireless systems ( wireless communication)
(BRAC University, 2011)
In this research, we will develop and test a niche which may be used as a
standard to convert wired links into wireless links. We will develop a step by step
procedure to identify the key parameters of a wired system ...
Design of a pure sine wave inverter for PV application
(BRAC University, 2011-10-11)
An inverter circuit by using Sinusoidal Pulse Width Modulation (SPWM) switching schemes is developed to run AC utilities. Inverter is a circuit that converts a DC source to an AC source. DC is one type of energy that is ...
Complete analytical model of GaN MESFETs for high power and Microwave frequency applications
(BRAC University, 2011-12)
In the past few years, growing interest has been paid to the wide band gap materials such as GaN because of its low thermal generation rate and high breakdown field for its potential use in high power, high temperature and ...
Design of a single phase switch mode AC-DC Converter
(BRAC University, 2011-12)
The people mover project
(BRAC University, 2011-05-03)
Performance analysis of a Multi-tone direct sequence code division multiple access (MT-DS-CDMA) system over a nakagami-m fading channel
(BRAC University, 2011-05)
Performance analysis has been carried out for a multi-tone DS-CDMA wireless communication system over a faded channel considering the channel limitations. The analysis is based on MT-DS-CDMA system and a rake receiver with ...
The evaluation of quality of transformer oil by measuring capacitance
(BRAC University, 2011-12-15)
Transformer oil plays an important role to keep transformer active and operate efficiently. It keeps transformer cool and works as an insulator between transformer windings and body. Due to arcing, corona discharge, ...
