Solar electric ambulance van unfolding medical emergencies of rural Bangladesh
(© 2016 IEEE, 2016-10)
Rickshaws are a key mode of transportation in Bangladesh. When it was changed to electrically-assisted ones, it achieved prevalence but was soon banned because of overconsumption of power from the national grid. In ...
The interference management and cost analysis perspective of femtocell in 4G network
(© 2016 IEEE., 2016-12-19)
Telecommunication has seen distinct upgrade since the innovation of wireless communication. The latest addition is LTE-Advanced. LTE-Advanced requires implementation of femtocell. Spontaneous femtocell deployment introduces ...
Learning algorithms for anomaly detection from images
(© 2017 IGI Global, 2016-08-30)
Visual surveillance networks are installed in many sensitive places in the present world. Human security officers are required to continuously stare at large numbers of monitors simultaneously, and for lengths of time at ...
Performing sentiment analysis in Bangla microblog posts
(© 2014 IEEE Computer Society, 2014)
Much of the research work on sentiment analysis has been carried out in the English language, but work in Bangla is limited to only news corpus and blogs. Microblogging sites are becoming a valuable source for publishing ...
Real-time monitoring of Solar Battery Charging Station
(© 2016 IEEE, 2016-08-31)
This paper represents a real-time monitoring technique of all the components of a Solar Battery Charging Station (SBCS). Its ability to generate clean energy at free of cost, along with availability almost all year round ...
Electrically facilitated solar cargo hauler - a key to easy and safe transportation of goods without dependency on the national grid
(© 2016 IEEE, 2016-10)
Cargo is a vital mode of transporting goods. In Bangladesh, most of the cargo haulers are manually driven in rural areas. If motorized, the cargos are likely to draw a huge amount of power from the national grid which in ...
A modular one-switch three-phase Single Ended Primary Inductor (SEPIC) rectifier
(© 2017 IEEE, 2017-04-26)
An input switch based modular Single Ended Primary Inductor (SEPIC) three phase AC-DC converter is proposed in this paper. The proposed rectifier has the advantage of step-up/down voltage gain with boost input stage. Input ...
Transient anode voltage modeling of IGBT and its carrier lifetime dependence
(© 2015 IEEE, 2015-11)
This work presents a minority carrier lifetime estimation technique through investigation into transient anode voltage modeling of Non-punch Through (NPT) Insulated Gate Bipolar Transistor (IGBT). Parabolic approximation ...
Transient anode voltage modeling of IGBT and its base doping profile investigation
(© 2015 Institute of Electrical and Electronics Engineers Inc., 2015-12)
In many power converter applications, study of doping concentration in the carrier storage region of IGBT is considered desirable. This paper introduces an estimation technique for base doping concentration through ...
Three phase one switch modular-boost/vienna power factor corrected (PFC) rectifier
(© 2017 IEEE, 2017-04-26)
The power conversion circuit of a three phase Vienna or Modular-Boost switching power factor corrected (PFC) rectifier uses three controlled switches, eighteen diodes and two output split capacitors. Three PFC controller ...
