A study on the challenges and importance of vehicular network in the context of Bangladesh
(© 2011 Institute of Electrical and Electronics Engineers Inc., 2011)The emergence of vehicular ad-hoc network (VANET) has provided the vital answer to vehicular communications. VANET can be either infrastructure based or simply lacking any. In our paper, we have dealt with an exemplary ... -
Evaluation of a mathematics program for preprimary children in rural Bangladesh
(© 2012 Elsevier Ltd, 2012)A randomized evaluation of a 9-month comprehensive math program for preprimary Bangladeshi school children addressed skills such as numbers, measurement, shapes, patterns, and space. Nine schools were randomly selected for ... -
Boost and buck topology based single phase AC-DC converters with low THD and high power factor
(© 2011 Institute of Electrical and Electronics Engineers Inc., 2011)Two topologies of single-phase Buck and Boost AC-DC converters are presented. Instead of using a single phase rectifier followed by a boost dc-dc converter, or using a bridge rectifier with two diodes and two switches, the ... -
Design challenges and scope for cognitive radio wireless networks in Bangladesh
(© 2011 Institute of Electrical and Electronics Engineers Inc., 2011)Standards groups and regulatory bodies around the world are increasingly seeking new ways of using and allowing access to allocating spectrum. In most parts of the world, cellular network bands are overloaded, but amateur ... -
Ćuk topology based single phase AC-DC converter wih low THD and high power factor
(© 2011 Institute of Electrical and Electronics Engineers Inc., 2011)To topologies of single-phase Ćuk AC-DC converters with low input current THD and high input power factor are proposed. Instead of using a single phase rectifier followed by a boost DC-DC converter, or using a bridge ... -
Feasibility and importance of an automatic controller for solar hot water system
(© 2011 Institute of Electrical and Electronics Engineers Inc., 2011)Being a developing country, Bangladesh has a very poor condition in terms of generating electricity. Alongside, natural resources like fuel and coal are in limited amount and will not be able to sustain forever. As a result, ... -
Effect of Fluctuating surface heat and mass flux on natural convection flow along a vertical flat plate
(© 2015 Hindawi Publishing Corporation, 2015)An investigation has been carried on double diffusive effect on boundary layer flow due to small amplitude oscillation in surface heat and mass flux. Extensive parametric simulations were performed in order to elucidate ... -
Nontraditional security challenges in South Asia
(© 2012 by The National Bureau of Asian Research, 2012)This NBR Monograph examines maritime security issues in Southeast Asia, including disputes over resources, piracy, and other threats to strategic waterways, and draws implications for U.S. policy in the region. -
Health threats as nontraditional security challenges for Bangladesh
(© 2012 National Bureau of Asian Research, 2012)This essay discusses health problems that have the potential to emerge as nontraditional security challenges for Bangladesh in the coming decades. -
