Finite element formulation employing higher order elements and software for one dimensional engineering problems
Corresponding Author : Razwan Ahamad (rahamad-mat@sust.edu)
Abstract : The paper concentrates to present finite element formulation of equilibrium problem in one dimension employing lower to higher-order finite elements and the development of the relevant software based on the explicit schemes. Present formulation is new and the elements of order one to tenth are considered and element matrices are presented in such a way that the code in any computer language can be developed easily. Finally, the efficiency and accuracy tested through the demonstration of application examples.
Synthesis, Characterization and Structure of an Iron-silyl Complex Containing Bis(silyl) Ligand Based on O-Heterocyclic Aromatics
Corresponding Author : Rockshana Begum (rockshana-che@sust.edu)
Abstract : The bis-(silyl)ligand-based on O-heterocyclic aromatic backbone DBFsil-H2 (1) were prepared by dilithiation of the 4,5-positions of dibenzofuran using n-BuLi in presence of tetramethyl ethelenediamine (TMEDA) followed by addition of chlorodimethylsilane. UV irradiation of Cp*Fe(CO)2Me and 1 in pentane produced Cp*Fe(DBFsilH)(CO)2 (2). X-ray diffraction analysis ensured the structure of complex 2 along with the rigid nature of the dibenzofuran core.
Application of Stochastic Frontier Model in Evaluating the Efficiency of Allowance related Public Safety Nets Programmes in Bangladesh
Corresponding Author : Dr. Md. Zakir Hossain (mzhossain.bds@gmail.com)
Abstract : The stochastic frontier model is usually used in estimating the technical efficiency of production of firms. Several social safety nets programmes in Bangladesh are working to protect individuals living in vulnerable conditions. Using the primary data of 130 rural clusters covering 620 households for old age people, 327 for widows and 173 households for disables, this study attempts to apply the stochastic frontier model to evaluate the efficiency of three main allowance related public safety nets programmes considering two outcome…
Localized states of modified Dirac equation
Corresponding Author : S.B. Faruque (awsbf62@yahoo.com)
Abstract : In this paper, we introduce an extension of the Dirac equation, very similar to Dirac oscillator, that gives stationary localized wave packets as eigenstates of the equation. The extension to the Dirac equation is achieved through the replacement of the momentum operator by a PT-symmetric generalized momentum operator. In the 1D case, the solutions represent bound particles carrying spin having continuous energy spectrum, where the envelope parameter defines the width of the packet without affecting the dispersion relation of the…
Spatio - Temporal Change Detection of Shoreline outside of the Coastal Embankment of Bangladesh: The Case Study on Barguna Sadar Upazila, Barguna District
Corresponding Author : Md. Bahuddin Sikder (bahuddinsikder@gmail.com)
Abstract : The main aim of this study is to delineate the shoreline change outside of the coastal embankment of Bangladesh. To fulfill this purpose, choose Barguna Sadar Upazila as a study area due to its unique position. This site is located at such a place where west and east side situated near the bank of the Bishkhali and Payra river, and in the south, the Bay of Bengal and these two rivers formed an estuary, which is the breeding place for…
Preparation of Nanostructured Iron Oxide Particles and Their Surface Functionalization with Oleic Acid, APTMS and Silver Nanoparticles
Corresponding Author : Nur Uddin Ahamad (nur-che@sust.edu)
Abstract : In this article, preparation of magnetic nanostructured iron oxide particles (IOs) and their surface functionalization with oleic acid, 3-Aminopropyltrimethoxysilane (APMTS) and Ag nanoparticles are reported. IOs particles were prepared by co-precipitation method and colloidal silver nanoparticles were synthesized by polyol method. The nanoscale IOs particles (<100nm) exhibited paramagnetic property and surface functionalization did not alter its magnetism. Colloidal stability of IOs particles is dependent on the nature of the surfactants. Necked IOs, and IOs functionalized with APTMS and Ag nanoparticles…
ANNIHILATOR IDEALS IN 0-DISTRIBUTIVE LATTICES
Corresponding Author : M.R. Talukder (r.talukder-mat@sust.edu)
Abstract : In this paper, we generalized some results of annihilator ideals for 0-distributive lattices. We prove that the set of all annihilator ideals of a 0-distributive lattice form a Boolean algebra. We also prove Stone type separation theorem for annihilator ideals of 0-distributive lattices.
Correlates of stunting and underweight among under five children of Sylhet district in north-eastern Bangladesh
Corresponding Author : Sumonkanti Das (sumonkanti-sta@sust.edu)
Abstract :
Sylhet is the most populated district in the north-east part of Bangladesh where half of the under-five children are either stunted or underweight. The correlates of stunting and underweight have not yet been explored extensively for the children of Sylhet district. This study aims to explore the correlates of stunting and underweight in Sylhet by selecting an appropriate logistic model for each of the indicators. A total of 809 under-5 children were selected in the household survey via two-stage cluster…
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…
