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. ...
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 ...
Performance analysis of a space time block coded MIMO system over faded channel
(BRAC University, 2011-04-20)
Performance analysis will be carried out for a MIMO wireless link with space time block
coding to find the performance over a Raleigh fading channel. The expression for the
signal and SNR at the receiver output will be ...
Performance analysis of a MIMO Optical wireless link with space time block code (STBC)
(BRAC University, 2011-04-28)
Performance analysis will be carried out for a space time block coded multiple input multiple output (MIMO) optical wireless link considering Nakagami-m fading model. The diversity reception in the receiving will be carried ...
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 ...
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, ...
Graphene as a replacement for Si in nano-electronics
(BRAC University, 2011-12)
In this paper, device manufacturing as a whole has been explored to discover whether graphene could be a
prospective material for device fabrication or not. As a part of this exploration, the current device manufacturing
process ...
Performance analysis of a free-space MIMO optical wireless link over strong atmospheric turbulences
(BRAC University, 2011-04)
Performance analysis will be carried out for optical wireless link with multiple transmitters & multiple receivers over a strong atmospheric turbulence channel. The receiver will be consisted of direct detection receiver ...
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 ...
