IoT based real-time synchronized clock
(BRAC Univeristy, 2018-04)
Maintaining the perfect timing is a necessity in every human life. We all are accustomed to clocks, both the analog and its digital counterpart. But, different clocks, even within the same geographical position, show ...
Study of AC-DC converter
(BRAC University, 2018-10)
The modern electronic devices operate with low DC output voltage. The AC utility supply needs
to be converted and step down to a suitable DC voltage. During earlier days, the converters were huge in size and were expensive ...
A detailed analysis on BUCK converter in different conduction mode
(BRAC University, 2018)
A DC-DC BUCK Converter is a basic type of switch mode power converter. It has variety of
application. It behaves differently in different conduction mode. In this thesis a buck converter is
designed first considering the ...
Simulation based distracted driver detection system using alcohol sensor and fusion of bioelectric signals to disseminate them through V2V/V2I to alleviate risky driving
(BRAC University, 2018)
The rampant road accidents due to drowsy or drunk driving and its dire consequences of
losing countless life including making million others maimed each year in the whole world,
which claims the attention of all concerned ...
Design of metamaterial loaded microstrip patch antenna array
(BRAC University, 2018-10)
Rectangular patch antenna is a commonly used antenna for the microwave ranges. It is easily
manufactured and has been studied thoroughly. But its size cannot be reduced as it is inversely
proportional to operating ...
Performance evolution of Spin Valve transistor
(BRAC University, 2018-08)
A necessity of new alternative for electronic devices are arising in which spin property of electron will be engaged for better energy efficiency. Combination of both ferromagnet and semiconductor materials opens the new ...
Wireless power transfer
(BRAC Univeristy, 2018)
Electric vehicles are making a new era in the world of vehicles and electronics where
Bangladesh has just started getting the touch of this technology. It is very efficient and a way of
saving our natural resources aiming ...
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. ...
Performance analysis of dye sensitized solar cell based on ZnO compact layer and TiO2 photoanode
(BRAC University, 2018-08)
Harnessing solar energy as an alternative solution to power production. Power can
be produced through burning fossil fuels. To gain optimum benefit through solar
energy is an extreme challenge for scientists and researchers ...
Crowdsourcing medical emergency system using Internet of things in Bangladesh perspective
(Brac University, 2018-12-25)
Bangladesh is a developing country with huge population in this small territory.
In population census 2011, we knew that our 7.48% populations are aged above
60 years of age. Also most of our people are unaware of the ...
