Smart power security system
(BRAC Univeristy, 2017)
Digital Bangladesh is still lacking of electricity. Electricity is the major source of power for most of the country's economic activities. So to decrease the power losses our team come up with a solution by planning to ...
Intelligent classroom management system
(BRAC University, 2013-12)
Modern day class rooms are equipped with electronic devices that have supporting software to improve and facilitate teaching methods. However, it is often seen that significant class time is wasted on taking attendance, ...
Fully automated satellite tracking system for directional antenna
(BRAC University, 2018)
When a Low Orbiting Cube satellite passes over a location it can receive and transmit HF/UHF frequency in a directional radiation. We get maximum efficiency when the satellite and the GS’s antenna stays in straight direction. ...
The application of Internet Of Things (IoT) to the traditional power grid
(Brac University, 2019-08)
The use of Internet of Things (IoT) in the traditional power grid has the potential to pave the way for the deployment of modernized Smart Grid in Bangladesh. This integration of IoT will not only cater for the exponential ...
Microcontroller based multilevel sun tracking solar PV system
(BRAC University, 2012-09)
Electricity generation has now become a mammoth task for a country like Bangladesh while development is directly proportional to energy production. It is also posing a great threat to our climate. Moreover, country like ...
Implementation of unnamed ground vehicle
(BRAC University, 2010-04)
Unmanned ground vehicles (UGV) are robotic platforms that are used as an extension of human capability. This type of robot is generally capable of operating outdoors and over a wide variety of terrain, functioning in place ...
Simulation based electrostatic study of different multigate quantumwell field effect transistors by changing the gate oxide thickness and metal work function
(BRAC University, 2016)
This paper analyses the C-V characteristics by altering the gate oxide thickness and metal workfunction used in the gate of non-planer, multi-gate InGaAs channel Quantum Well Field-Effect Transistor (QWFET). In this paper, ...
Wimax security analysis
(Department of Electrical and Electronic Engineering, 2011-04-28)
Worldwide Interoperability for Microwave Access (WiMAX) is a wireless metropolitan area network (WMAN) communications technology using the IEEE 802.16 standard. The original purpose of IEEE 802.16 technologies was to provide ...
A comparative study of DC/AC pure sine wave inverters
(BRAC University, 2013-12)
A power inverter or inverter is an electrical power converter that changes direct current (DC) to alternating current (AC). The converted AC can be at any required voltage and frequency with appropriate transformer, switching ...
Optimisation of photonic crystal weveguide based optical filter
(BRAC University, 2013-04)
Photonic integrated circuits (PIC) based on Photonic Crystals are becoming increasingly favoured in emerging signal processing and optical communication technologies. Photonic crystals (PhCs) are periodic dielectric ...
