    • Performing sentiment analysis in Bangla microblog posts 

      Chowdhury, Shaika; Chowdhury, Wasifa (© 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 

      Priyanka, Mirza Karishma; Chowdhury, Abrar Alvi; Mahmud, Bushra; Chowdhury, Sheri Jahan; Azad, Akm M.M.Abdul Malek (© 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 ...

    • Solar electric ambulance van unfolding medical emergencies of rural Bangladesh 

      Tarek, R.; Anjum, Adiba; Hoque, Md Ashiqul; Azad, Akm M.M.Abdul Malek (© 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 ...

    • Three phase one switch modular-boost/vienna power factor corrected (PFC) rectifier 

      Uddin, Mohammad Nasir; Abedin, Amina Hasan; Bashar, Khandaker Lubaba; Islam, Samia M.Naeemul; Choudhury, Mohammad Ali A.Shoukat (© 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 ...

    • Transient anode voltage modeling of IGBT and its base doping profile investigation 

      Das, Avijit; Md Ziaur Rahman, Khan (© 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 ...

    • Transient anode voltage modeling of IGBT and its carrier lifetime dependence 

      Das, Avijit; Islam, Nazmul; Haq, Masud Ul; Khan, Ziaurrahman (© 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 ...

    • Two switch three phase ĆUK regulated rectifier 

      Abedin, Amina Hasan; Choudhury, Mohammad Ali A.Shoukat (© 2016 IEEE, 2016-11-22)
      A three phase Vienna/Modular-Boost rectifier provides only boost voltage gain regulation using three single phase PFC controller to achieve power factor correction and input current waveform improvement. A Buck-Boost voltage ...
