Analysis of Thyristor based dual converter controlling the firing angle for HVDC transmission
(BARC University, 2017-12)
Electricity is one of the most reliable energy sources because it can be converted into any form of energy and can easily be transmitted from one place to another. For transmission purpose we use Alternating current because ...
Portable environmental monitoring system
(Brac University, 2019-04)
In this modern world of 21st century, the development of new technologies is rapid than in the past.
People are more concerned about new industries and businesses. As a result, environment has
become less important to ...
A metering network for a smart prepaid scheme under an electrical utility organization
(Brac University, 2020-10)
The present prepaid metering scheme is connected to server mainly using the GSM network.
It creates an inherent dependence on mobile companies. Moreover, there is always an
operational (recurring) cost to maintain different ...
Green IoT based plant growth monitoring system
(Brac University, 2018-12)
The usage of Internet of things (IoT) for plant advancement and natural organization is a promising new field of research. Here an arrangement of reliably interfaced sensors are used to support data went for giving more ...
Development of Torque Sensor Based Electrically Assisted Hybrid Rickshaw
(Department of Electrical and Electronic Engineering (EEE), 2012-09-04)
Cycle rickshaws are the most popular form of transportation inside the cities of
Bangladesh, especially for its route and time-flexibility and door-to-door services.
Considering the fact that a significant portion of ...
Information transmission through a quantum information channel
(BARC University, 2017-12)
We consider the transmission of classical information over a quantum chan-
nel. The channel is expressed by an alphabet of quantum states. For an
example, we can express quantum states by photon polarization. For ...
Design and development of a stepper motor position control system in micro-stepping mode using Atmega32 Microcontroller
(BRAC Univeristy, 2018-04)
Stepper motor mainly operates on open loop controller which actually causes loss of steps and slip of steps and so closed loop position control is being developed to overcome these drawbacks. The controller is usually of ...
Development and implementation of a battery and solar powered DC compressor based cold storage for off grid rural areas ensuring food security
(BRAC University, 2016)
Preserving perishable goods as soon as they are harvested is the main concern for the farmers in the rural areas of Bangladesh for lack of cold storage facilities and absence of electricity supply. To supply ample facilities ...
Development of electric stove for smart use of Solar Photovoltaic energy with national grid
(BRAC University, 2013-12)
Saving energy is now one of the major concerns for the researchers. Still a lot of fossil fuels are being consumed directly or indirectly just for cooking and hence affecting the global environment. With the rapid increase ...
Photovoltaic performance of P3HT:CNT:PCBM based bilayer solar cell
(BRAC University, 2016-04)
Organicbilayer solarcells have the potential to replace silicon based solar cell devices due to its low cost fabrication cost and high mechanical flexibility. However, despite possessing such remarkable properties their ...
