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…

An Overview of Geology, Hydrogeology and Open Pit Mining Perspective of the Phulbari Gondwana Coal D

Corresponding Author : Mohammed Omar Faruque (faruque_pge@yahoo.com)

Abstract :

The Phulbari coal deposit is one of the largest coal reserves in NW Bangladesh. The country requires exploring this resource to overcome the present energy crisis. Two types of mining methods-open-pit and underground, might be considered for the exploration of coal worldwide. However, depths of the coal seam, geological, and hydrogeological circumstances of the Phulbari area vigorously disfavor open-pit mining. In this article, geology and hydrogeology of the area have been reviewed first, and then Boundary Element Method (BEM) numerical…

Comparable Analysis of Engineering Properties between Crushed Hardrock Dust of Maddhyapara Granite M

Corresponding Author : Tareq-Uz-Zaman (dmfh75@yahoo.com)

Abstract :

This paper reports the experimental study undertaken to investigate some engineering properties of crushed hardrock dust of Maddhyapara Granite Mine (MGM), Dinajpur and natural sand. Engineering properties of these two materials have been compared to draw a conclusion for whether crushed hardrock dust can be used as an alternative of sand in construction work. The properties that were determined are fineness modulus, bulk specific gravity, apparent specific gravity, absorption capacity, unit weight, percentage of voids and relative density. Besides, the…

Comparative Study of Biodiesel Preparation Methods

Corresponding Author : Kaniz Ferdous (engr_kaniz@yahoo.com)

Abstract :

Biodiesel is usually produced from food-grade vegetable oils using transesterification process. Base catalyzed transesterification reaction is widely used for biodiesel production from vegetable oil due to its faster kinetics than that of acid catalyzed process. But if free fatty acid (FFA) content in the oil is more than 2%, the base catalyzed process is not feasible. In the present paper biodiesel is prepared from non-edible oils, such as nahor seed oil (NSO) and rubber seed oil (RSO) by different methods.…

Earthquake Vulnerability Assessment of Schools and Colleges of Sylhet, a North-eastern City of Bangl

Corresponding Author : M. Ahmed (mushtaq_cee@yahoo.com)

Abstract :

Sylhet, the north-eastern divisional city of Bangladesh, is one of the most earthquake prone areas of the country. In this paper, seismic vulnerability of the educational institutions of Sylhet city has been assessed. Rapid Visual Screening (RVS) and Modified Turkish Method have been used to evaluate the seismic vulnerability of the existing school and college buildings of the city. More than fifty schools and colleges have been surveyed with an objective to identify the most vulnerable buildings, so that retrofitting…
