Design of an efficient energy harvester from ambient vibration
(BRAC University, 2012-04)The aim of this thesis was to design and an efficient energy harvester from ambient vibrations. An energy harvester is merely a device that will convert ambient energy into some usable electrical energy. In this work we ... -
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 ... -
Study of soliton propagation inside optical fiber for ultra-short pulse
(BRAC University, 2011-12-15)We will study the pulse propagation in optical fiber. The effect of non-linearity and dispersion of the pulse propagation causes temporal spreading of pulse and it can be compensated by nonlinear effect. When the effects ... -
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 ... -
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, ... -
Data processing through biosensors and development of simulation software in windows & RT-Linux
(BRAC University, 2012-04-05)Solving real life problems are often very time demanding due to the high sensitivity of the system such as biomedical devices which are actually used to get data to represent the critical state of a human or animal body. ... -
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 ... -
Virtual Mouse: Design and implementation of an accelerometer based wireless mouse
(BRAC University, 2011-12-15)The concept of Accelerometer Based Hand Action Recognition is a known phenomenon and has its execution in the field of gaming controller. By the use of this concept, we intend to build up a device that we would like to ... -

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 ... -
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 ... -
People mover project (control system part)
(BRAC University, 2011-12-07)People-Mover is an electrical self-motivated medium. The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks, but is sometimes applied to ... -
Designing and implementation of a intensity based fiber optic vibration sensor
(BRAC University, 2011-04-28)This paper describes the design of an intensity based fiber optic displacement sensor, which can measure the amplitude and frequency of the vibration . The proposed device consists of a fiber optic transmitter, photodiode ... -
