An enhanced tree based key management scheme for secure communication of wireless sensory network
(BRAC University, 2010-04)
Wireless sensor networks (WSN) are mobile ad hoc networks in which sensors have limited resources and communication capabilities. Secure communications in some wireless sensor networks are critical. Key management is the ...
Design a solar clean car
(BRAC University, 2012-04)
Prior to year 2000, most vehicles in Bangladesh were used to run on petroleum. Though we have to import it and in international market the demand of petroleum oil is always higher than the supply and that’s why it is always ...
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 ...
Contingency analysis and reliability evaluation of Bangladesh power system
(BRAC University, 2011-04)
An over-riding factor in the operation of the power system is the desire to maintain security and expectable reliability level in all the sectors- power generation, transmission and distribution. System security can be ...
Design and VLSI implementation of high performance face recognition system
(BRAC University, 2013-04)
In this paper, we have proposed a novel hardware architecture for face-recognition system. In order to make the system cost effective we have used a simple yet efficient algorithm of face-recognition system. We have designed, ...
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 ...
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 ...
Location based service for the mobile users using the GPS technology
(BRAC University, 2012-12-15)
Mobile phone- a mass media for making communication & sharing information in present days among the people has been enriched with different applications by the advancement of internet & network technology. It brought the ...
Developing a remote control for digital data transmission using infrared and rario frequency : wireless communication
(BRAC University, 2013-04-27)
In this work we will first realize a TV remote control system. The system will allow digital data to be transmitted over a significant distance using a radio link where the input will be infrared (IR) signal. As a result ...
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 ...
