A Fine-Grained Tagset for Bengali Language

Corresponding Author : Md. Abdullah Al Mumin (mumin-cse@sust.edu)

Abstract :

The lexical tags, called Tagsets, play a significant role providing the large amount of information about a word and its neighbors, telling us something about how the words are pronounced, being used in stemming for information retrieval[1]. So, a standard tagset is necessary for working with a language in any computational linguistic field. Two major kinds of tagsets for a language are fine-grained tagset, which uses a large number of tags, and coarsegrained tagset, which uses a small number of…

An Enhanced Selection Sort Algorithm

Corresponding Author : Md. Khairullah (khairullah-cse@sust.edu)

Abstract :

Sorting is a commonly used operation in computer science. In addition to its main job, sorting is often required to facilitate some other operations such as searching, merging and normalization. There are many sorting algorithm that are being used in practical life as well as in computation. A sorting algorithm consists of comparison, swap, and assignment operations. In this paper an enhanced version of the classical selection sort algorithm is presented, which eliminates some unnecessary comparisons to find the maximum…

Antibacterial Activity and DNA Interaction of the Pd(bpy)(ONO2)2 Coordination Complex

Corresponding Author : Muhammad Younus (myounus-che@sust.edu)

Abstract :

Antibacterial activity of Pd(bpy)(ONO2)2 complex (bpy = bipyridine) was studied by disc diffusion method against Escherichia coli, Staphylococcus aureus, Klebsiella oxytoca, Pseudomonas aeruginosa and Enterococcus faecalis. The compound was found to be active against the bacteria. DNA binding constant of that complex was studied with extracted DNA from lemon by UV-Vis spectroscopy. The calculated binding strength was found to be 2.09×106 which is significantly higher than that of the [Pd(bpy)(OH2)2] 2+ complex with CT-DNA.

Calculation of Travelling Velocity of an Axisymmetric Vortex Ring

Corresponding Author : T. K. Sheel (tarunbd@gmail.com)

Abstract :

An initial value problem of the Navier-Stokes equation is solved, at low Reynolds numbers, for evolution of an axisymmetric vortex ring. The travelling velocity is written down in closed form over the whole time range, in term of the generalized hyper geometric functions, for a vortex ring starting with infinitely thin core. We show how the ideas of topology and variation principle, opened up by Euler, facilitate the calculation of motion of vortex rings. We consider finiteamplitude Kelvin waves on…

Catalytic Activity of 0.4% Rh Supported ZrP2O7 Catalyst for the NO-CO-C2H6-O2 Reactions Under Modula

Corresponding Author : Ahmed Jalal Samed (ajf-che@sust.edu)

Abstract :

Catalytic activity of the 0.4% Rh/ ZrP2O7 catalyst for the NO-CO-C2H6-O2 reactions under modulated air-to-fuel ratio (A/F) conditions were studied with a view to evaluate its catalytic performance under both oxidizing and reducing environment. In situ EXAFS experiments were carried out further to evaluate its catalytic performance. This newly developed catalyst exhibited outstanding 85% NO removal efficiency in oxidizing environment where conventional 0.4% Rh/ZrO2 catalyst showed 45% NO removal efficiency. The strong Rh-O-P linkage has been confirmed by EXAFS investigation…

DWBA Study of Reactions Using Different Optical Potentials

Corresponding Author : S. K. Das (skdas-phy@sust.edu)

Abstract :

Full Finite Range (FFR) Distorted Wave Born Approximation (DWBA) calculations have been performed using non-monotonic shallow (molecular), non-monotonic deep, Michel (SWS) and Woods-Saxon (WS) potentials to analyze the angular distributions of cross section for Ni t Cu 60 62, 64, 61 63, 65, (α, ) reactions at the incident energy 26.7 MeV. Shallow potentials and normal Wood-Saxon (WS) potential seem to be a bit better candidates for fitting experimental data. The spectroscopic factors are extracted for different potentials and compared…

Extended Bangla Keyboard

Corresponding Author : M. R. Selim (selim@sust.edu)

Abstract :

Bangla language has a big size character set. To fit all the characters within the existing keyboards, all the Bangla fixed keyboard layouts use several typing layers. Since using characters of a non-default typing layer requires pressing an extra key, it slows down the overall typing speed significantly. In this paper, to reduce the effect of multilayer typing, we propose to add some extra keys in the keyboards used by the Bangla language users. We show quantitatively the efficiency improvement…

Jordan Generalized k-Derivations of Completely Prime ΓN-Rings

Corresponding Author : Sujoy Chakraborty (sujoy_chbty@yahoo.com)

Abstract :

In the theory of gamma rings, it is evident that every generalized k-derivation of a Γ-ring M is a Jordan generalized k-derivation of M. Here we show, in particular, that its converse is also true if one chooses M as a 2-torsion free completely prime ΓN-ring.

Of Boullée and Kahn, and the Spirit of the Sublime

Corresponding Author : K. Taufiq Elahi (elahi-arc@sust.edu)

Abstract :

If we look at the string of development-trend in architectural history and theory in a broader spectrum, it would have been seen that two diverse but distinctive ideals have waged war against one another throughout the centuries. The rationalists were the pioneers amongst the two – as far into the past as texts were found on building art and its relevant issues – they sought for absolute truth and beauty in every object of creation, believing in their hearts that…

Spatial Distributions of the Axis of Coherent Fine Scale Eddies in Turbulence

Corresponding Author : M. Ashraf Uddin (auddin-mat@sust.edu)

Abstract :

Spatial distributions of axis of coherent fine scale eddies in turbulence are discussed by using visualization with some physical insights. The axes are determined from DNS data of decaying homogeneous isotropic turbulence up to Reλ =87.9. Visualizations of the axes in the volume unit of integral length scale (lE), Taylor microscale (λ) and Kolmogorov microscale (η) are compared by selecting the visualized width of axes as constant value, square root of Qc * and Qc * , respectively, where Qc…

SUMono: A Representative Modern Bengali Corpus

Corresponding Author : Md. Abdullah Al Mumin (mumin-cse@sust.edu)

Abstract :

The development of Language Engineering applications requires availability of sizable, reliable and representative corpora. However, such corpora are not routinely available for Bengali language. This paper introduces Shahjalal University Monolingual (SUMono) corpus, a representative modern Bengali corpus consisting of more than 27 million words, which is the largest of its kind. This paper describes how we have constructed SUMono corpus from available online and offline Bengali texts, with articles tagged as belonging to 6 domains: Natural Science, Social Science, Computer…

Abstract :

The object of this paper is to characterize the unit-regular Γ- rings. In this paper we prove some basic properties of regular gamma rings and develop a number of equivalent characterizations of the unit regularity of regular Γ-rings. We finally prove that the class of all unit-regular Γ-rings is a radical class.
