A Modular Landscape Model for Low Cost Settlement. Case study: Sylhet, Bangladesh
Corresponding Author : Mohammad Shamsul Arefin (msan_arch-arc@sust.edu)
Abstract : This study aims to innovate an affordable landscape design model for under privileged urbanized areas of a growing cities. The lower income population from rural areas, frequently migrate to the urban areas for short or long-term basis to ease their poverty. This internal migration takes place for several reasons caused by manmade and natural disaster and dream of better life expectancies. These migrant people may get work and money in a certain number per single family, but it keeps them…
Assessment of Occupational Injuries, Health, and Risk Faced by the Workers in the Engineering Workshops: A Survey Based Approach
Corresponding Author : Pronob Kumar Biswas (pronob-ipe@sust.edu)
Abstract :
This study assesses the attributes of occupational injuries among workers, and the risk associated with the hazards prevailed in engineering workshops. Injury data were collected using a semi-structured questionnaire. Pareto analysis was performed to find the vital few from trivial many. The associated risk levels were measured using a Semi-Quantitative Risk Assessment Matrix. 92% of the worker used to work more than 8 hours per day and 75% of injuries were found to occur after 8 hours of working period.…
Seismic Performance of Building with Haunched Beams by Simplified Non-Linear Static Analysis (NSA)
Corresponding Author : Md. Foisal Haque (mfh.civil@gmail.com)
Abstract : Haunch mechanism of beam influences on the building performance under seismic loading. Displacement coefficient method expresses better performance of haunch than capacity spectrum method. Actually, evaluation of overall performance of a building is very complex because many primary and secondary components are involved with it. However, in this paper, seismic performance of 12-storied building with haunched beams is evaluated by displacement controlled non-linear static analysis (NSA) by using ETABS. Two variable parameters effect on overall performance of building and individual…
Distribution of Internal Rural-Urban Migration in Bangladesh: Application of Probability Models
Corresponding Author : Dr. Md. Zakir Hossain (mzhossain.bds@gmail.com)
Abstract : The study of migration through probability models is very crucial for an in-depth understanding of the pattern, the volume of migration, and the factors acting on it. The study is devoted to the application of probability models to describe the pattern of household-level migration in Bangladesh. The probability models have been tested using a nationwide representative dataset of Bangladesh generated by the project “Rural-urban Migration and its Implications for Food Security in Bangladesh” under the National Food Policy Capacity Strengthening…
Synthesis and Characterization of Palladium Acetylide Complexes with Heterocyclic N-Donor Ligands
Corresponding Author : Muhammad Younus (myounus-che@sust.edu)
Abstract :
Mono- and bis-acetylide complexes of palladium with two different N-donor ligands of the type cis-[Pd(LL)(C≡CR)2] (LL = 1,10-phenanthroline, R = C6H5 3, and LL = 2, 2-bipyridine, R = C6H5 5) and [Pd(LL)Cl(C≡CR)] (LL = 1,10-phenanthroline, R = C6H5 4, and LL = 2, 2-bipyridine, R = C6H5 6) were prepared by the dehydrohalogenation reaction between cis-[Pd(LL)Cl2] and phenyl acetylene ligand. The complexes were characterized by IR, UV-vis spectroscopy. These palladium-carbon σ-bonded complexes were sensitive to air in contrast to…
Monte Carlo simulation of Bose-Einstein condensation in a harmonic potential trap
Corresponding Author : Dr Md Enamul Hoque (mjonyh-phy@sust.edu)
Abstract : Bose-Einstein condensation has been attained using Monte Carlo simulation on non-interacting ideal bosons confined in a harmonic potential trap at near-zero temperature (~0K). A connection has been established between the cyclic paths originated by the interchange of identical bosons and condensation. At low temperatures, long cycles appear and condensation is obtained consequently. The simulated result is in perfect agreement with the corresponding theoretical findings.
Simulation of Waveform Generator

Abstract : Dirac's equation deals with the electromagnetic interactions in quantum mechanics. This equation can be modified for the classical modulated waveform. This paper presents a simulation approach for generating electromagnetic wave packets from the modified Dirac's electromagnetic equation solution. From this solution, an equivalent numerical circuit using SIMULINK is designed. This numerical circuit generates an exact amplitude modulated waveform of the solution. An analog circuit of the equation using op-amp is also designed with SIMULINK. The circuit generates an amplitude modulated…
Photoluminescence Quenching in blends with Poly(3-hexylthiophene) and Fullerene/Non-fullerene Acceptors
Corresponding Author : Nazia Chawdhury (nc-phy@sust.edu)
Abstract :
Photogenerated charge transfer behavior from a p-type poly(3-hexylthiophene) (P3HT) donor material to an n-type fullerene and non-fullerene acceptor materials have been studied in blend solution with the help of photoluminescence (PL) quenching. The PL spectra were studied using two different excitation sources. The small gap fullerene-ethyl nipecotate and phenyl-C61-butyric acid methyl ester (PCBM) are fullerene-based and poly naphthalene-bithiophene (N2200) is a non-fullerene-based n-type acceptor material used in this research work. Observation shows that the P3HT:N2200 blend with a weight ratio…
Biomass and Carbon Estimation of the Four Major Tree Species in Ratargul Swamp Forest, Bangladesh

Abstract : Wetland forests– a major ecosystem of Bangladesh, is still being neglected despite of having enormous potentials particularly in case of ecosystem balancing and CO2 accumulation. Under this purview, the present study aimed at estimating the biomass and carbon stock of four major tree species namely Pongamia pinnata, Barringtonia acutangula, Syzygium fruticosum and Lagerstroemia speciosa at Ratargul swamp forest under Sylhet Forest Division. Thirty sample plots (20 m × 20 m) were taken to enumerate biomass and carbon stock of the…
Are Diamond’s assembly rules applicable in tropical threatened vascular plants assemblages in the Tarap Hill Reserve in Bangladesh?
Corresponding Author : Mahmuda Sharmin (m.sharmin@westernsydney.edu.au)
Abstract : Disentangling the co-existing patterns (random or non-random) of species and to infer about assembly rules underpinning the observed patterns are central research issues in community ecology. Previous empirical results suggested that Diamond’s assembly rule explains a considerable amount of observed species spatial distribution pattern variation. However, the rule has yet to be checked in tropical forests where plant communities experience high anthropogenic disturbances and rapid conversion of natural forests has resulted in fragmented forests with many threatened species. In this…
