Causes of Subsidence In and Around the Baropukuria Coal Mining Area, Dinajpur, Bangladesh: Insight f
Corresponding Author : M. Farhad Howladar (dmfh75@yahoo.com)
Abstract :
The subsidence around the Baropukuria Coal Mine field is the most important and major hazards or threats for safely extracting the coal from underground. From this point of view, the present research mainly investigated the causes of subsidence and its possible preventive plans by direct field investigation method. The analysis shows that subsidence is caused by many factors such as applied mining method, multi-sliced ultra thick coal seams, less competency of overburden strata, depth & dip of the coal seam,…
Design and Implementation of Mongol Dip: Software for the People with Visual Impairments

Abstract :
The software Mongol Dip helps people with visual impairments to operate windows operating system for computational tasks. In this software we have used text to speech technology to echo every operation done by the user. This software assists people to move through the disk spaces and open documents, rich media files as well as working with these files. This software use Microsoft Speech API and Bengali Text to Speech application “Subachan” to read out the contents of the document in…
Natural Gas Properties Analysis of Bangladesh: A Case Study of Titas Gas Field
Corresponding Author : Mohammad Islam Miah (dmfh75@yahoo.com)
Abstract :
Titas is the largest gas field in Bangladesh and the highest gas producer in the country at present which was discovered in 1962 by Shell Oil Company, Pakistan. In designing gas production, processing, transport and handling systems, a complete knowledge of natural gas properties is crucial. For this reason, a detailed research has been done for the measurement and prediction of hydrocarbon fluid properties. This research shows the reservoir of natural gas properties analysis of Titas gas field from gas…
WEBTracker: A Web Crawler for Maximizing Bandwidth Utilization
Corresponding Author : Md. Ruhul Amin (shajib-cse@sust.edu)
Abstract :
The most challenging part of a web crawler is to download contents at the fastest rate to utilize bandwidth and processing of the downloaded data so that it will never starve the downloader. Our implemented scalable web crawling system, named as WEBTracker has been designed to meet this challenge. It can be used very efficiently in the distributed environment to maximize downloading. WEBTracker has a Central Crawler Server and it administers all the crawler nodes. At each crawler node, Crawler…
Synthesis and Characterization of a Bis(silyl) compound Based on O-Heterocyclic Aromatics
Corresponding Author : Rockshana Begum (rockshana-che@sust.edu)
Abstract :
A new bis(silyl) compound based on O-heterocyclic aromatics with the dibenzofuran backbone was prepared by dilithiation of the 4,5-positions of dibenzofuran using n-BuLi in the presence of tetramethylethylenediamine (TMEDA) followed by treatment with chlorodimethylsilane. The product DBFsil2 was characterized by 1H NMR, 13C NMR, 29Si NMR, Mass (EI) and Elemental analysis.
SUPara: A Balanced English-Bengali Parallel Corpus
Corresponding Author : Md. Abdullah Al Mumin (mumin-cse@sust.edu)
Abstract :
Parallel corpora have become an essential resource in natural language processing. In spite of their importance in many multi-lingual applications, a few effective English-Bengali corpus has been made available, given the scarcity of its resources and the intensive lobors required in its creation. This paper introduces Shahjalal University Parallel (SUPara) corpus, an English-Bengali sentence-aligned parallel corpus consisting of more than 200,000 words in either languages, which is the largest among freely released corpus of its kind. A balanced corpus refers…
Some Characterizations of J--Rings
Corresponding Author : Md. Mahbubur Rashid (mrashid_math@yahoo.com)
Abstract :
The purpose of this paper is to introduce J-Γ-rings and a few of their most basic properties.
We first study on the commutativity of J-Γ-rings and then we see that the class of all J-Γrings is a radical class. We next study a couple of necessary and sufficient conditions for
J-Γ-rings. We also develop some other characterizations of J-Γ-rings.

40Ca(6Li,d)44Ti Reaction and Effect of Three Potentials on the Spectroscopic Factors
Corresponding Author : U. K. Mazumder (skdas-phy@sust.edu)
Abstract :
Full finite-range distorted-wave Born approximation method has been applied to analyze the angular distribution of cross-sections of 40Ca(6 Li,d) 44Ti reaction for the 32 transitions involving both the bound and unbound states of 44Ti by using the normal optical, Michel and molecular potentials. As far as we know, Michel and molecular optical potentials have been used for the first time in analyzing these reaction data. All the three optical potentials are found to produce satisfactory fits to the experimental data.…
Measurement of the Nonlinear Refractive Index of LiNb03 by Z-scan Technique
Corresponding Author : S. M. Sharif (sharif-phy@sust.edu)
Abstract :
Nonlinear refractive index, n of an undoped z-cut photorefractive LiNbO3 crystal has been investigated here by the Z-scan technique using a continuous wave (cw) laser beam from a multiline argon-ion laser. Here both the sign and magnitude of the measured n are considerably different from the reported z-scan result in LiNbO3 obtained with picoseconds pulsed laser at 532 nm but in good agreement with other reported value with a cw laser beam at 514 nm. In the present work, the…
