Affordable Electricity for Bhashan Char from Renewable Energy

Abstract: Bangladesh is a developing country with energy problem causing various after effects like load shedding, energy distribution & transmission. Major problem is population and adding more population may end in more scarcity of electricity distribution. Rohingya people fled away from Myanmar makes the number of population rising and energy problem is also increasing with more people as Bangladesh Government decided to relocate them in an island called Bhashan Char (Also known as Thenger Char, Char Piya). Bhashan Char is located at the southwest part of Bangladesh away from the main land and in the Bay of Bengal. Energy distribution from National grid is not a solution to the problem and as it is a remote area and detached from the main land transmission from the National grid is not feasible. The only solution is to provide electricity with renewable resources by means of PV, Wind or any other electricity generation systems. The HOMER simulation software was used for the design. The software also predicts the cost of electricity with sustainable manners. The proposed system has per unit electricity cost of 8.9 BDT.

Feature based semantic analyzer for parsing Bangla complex and compound sentences

Abstract: Semantic analyzer determines the semantic meaning of the words in a sentence. This paper proposes a semantic analyzer that can semantically parse the Bangla sentences. Without semantic analysis, it is very difficult to find the accurate meaning of the translated sentences in one language into their equivalent sentences in other language. To analyze the Bangla sentences semantically, this study identifies a set of features of each word categories in Bangla. Experimental results show that proposed features can be used effectively for analyzing all kinds of Bangla sentences with semantic analyzer.

Design of a Miniature Microstrip Wide Band Antenna for On-body Biomedical Telemetry

Abstract: In this paper, a compact microstrip wideband antenna is proposed for on body biomedical application. The antenna is designed to operate in the Industrial, Scientific and Medical band at 2.45GHz. The overall dimension of the recommended antenna is 30 × 40 × 1.76 mm3 and has an open end slotted fed line and a slotted ground plane. Parasitic patch is used to enhance the bandwidth of the recommended antenna. The main features of this antenna are low profile, flexible, wideband and biocompatible. The performance of the proposed antenna is analyzed in terms of impedance bandwidth, return loss (dB), VSWR, Specific Absorption Rate (SAR), radiation pattern, gain, and directivity. The antenna performance is analyzed in a three-layer human phantom model. The results obtained from the simulation show an impressive impedance matching having a return loss of around −48.99 dB at 2.45 GHz and the bandwidth coverage of nearly 900 MHz. To design & simulate the antenna, CST (Computer Simulation Technology) Microwave Studio is used.

Performance of reinforced concrete hospital building subjected to earthquake using base-isolation system

Abstract: The frequent occurrence of earthquake in the Bangladesh and up-gradation of seismic design code (BNBC-1993) has heightened the need for investigation of seismic performance of existing lifeline structure specially hospital building. The objective of this study is to evaluate seismic capacity and corresponding improvement of an existing hospital building (Ancillary Building) of Chittagong Medical College Hospital (CMCH). For this purpose, a three dimension (3-D) numerical model of Ancillary Building (AB) of CMCH was developed using SAP 2000 finite element program. A non-linear static analysis was performed to determine seismic capacity of the building model. The result indicates the seismic capacity of the hospital building is sufficient to mitigate the seismic demand according to BNBC-1993, whereas the seismic capacity is found insufficient as per revised BNBC. To reduce the seismic effect on AB, base-isolation devices have been designed and were used as link element to the numerical model. The application of base-isolation devices as a retrofitting strategy makes the considered hospital building safer for seismic excitation suggested in revised BNBC.
