Evolutionary based maximum power point tracking technique using differential evolution algorithm
(Elsevier B.V., 2013)
This paper presents a maximum power point tracking (MPPT) technique for photovoltaic (PV) system using a modified differential evolution (DE) algorithm. The standard DE is modified to deal with dynamic objective function ...
Performance improvement of dye sensitized solar cell by using recycle material for counter electrode
(Trans Tech Publications, 2013)
This project is to investigate the counter electrode material from two different carbon sources to fabricate dye sensitized solar cell (DSSC). The carbon sources are extracted from battery and pencil lead. The method to ...
Development of pyramidal microwave absorber using sugar cane bagasse (SCB)
(EMW Publishing, 2013)
The need to find ways to effectively utilize the large quantities of agricultural waste that are produced is indicative of the huge potential associated with producing an alternative pyramidal microwave absorber for anechoic ...
Design of UHF harmonic butterworth low pass filter for portable 2 ways-radio
(Engg Journals Publications, 2013)
This paper presents the design of a compact Butterworth low pass filter designed operating at frequency range of 300-400MHz with input and output impedance of 50 ohm have been designed, simulated and fabricated. This filter ...
A comparative study of confined carrier concentration of laser using quantum well and quantum dot in active layer
(Trans Tech Publications, 2013)
This paper presents a comparative analysis of the characteristics of confined carrier concentration in the gain medium as well as the carrier concentration at the threshold. We have studied extensively these phenomena by ...
The influence of human head model wearing metal-frame spectacles to the changes of SAR and antenna gain: Simulation of frontal face exposure
(EMW Publishing, 2013)
The relationship between specific absorption rate (SAR) and antenna gain inside the head due to the metal-frame spectacles was investigated. The radio frequency (RF) energy source considered is the smartphone used in the ...
Optimal overcurrent relay coordination: a review
(Elsevier Ltd., 2013)
This paper presents an overview on optimal overcurrent relay coordination in protection system and protective relays. Efforts have been made to include all methods used for the coordination of overcurrent relays. It includes ...
Smart receiver system of green hybrid antennas
(Wiley Periodicals, Inc., 2013-04)
A hybrid of multiformities receiver system is proposed in this article.The system is developed through a combination of reconfigurable beam-steering antenna, reconfigurable beam-shaping antenna, and data acquisition (DAQ) ...
Resemblance of rain fall in Bangladesh with correlation dimension and neural network learning
(Science Publication, 2013-10)
Rain fall and Temperature are undoubtedly two important factors that balance water in the environment. Adequate study of the rain behavior helps to forecast it. The time series obtained from different stations of the country ...
An earth fault location scheme for isolated and compensated neutral distribution systems
(Praise Worthy Prize S.r.l., 2013-10)
This paper proposes a scheme to locate an earth fault in an unearthed or a compensated neutral medium voltage (MV) network using the transient signal recorded from MV/LV substations. The algorithm applies continuous wavelet ...
