Abstract : This study mainly focuses on the quantification of various components of water balance of the Surma basin in Sylhet City using Geographic Information Systems (GIS) and The Soil and Water Assessment Tool (SWAT) model. This study has been carried out to understand the relationship among the basin’s water balance elements, the water accessibility, and watershed features of the Surma river basin, which is essential for sustainable water resource management and planning of Sylhet city. ArcGIS software is used to process…
Preliminary Assessment of Earthquake Vulnerability of RC Buildings by Japanese Index Method
Corresponding Author : Mushtaq Ahmed (mushtaq_cee@yahoo.com)
Abstract :
The principal observation of this study is emphasized on the structural seismic evaluation of low to medium-rise buildings and it is tried to establish the Japanese Index Method as a precise and user-friendly structural vulnerability assessment method for reinforced concrete (RC) buildings. In this study, a detailed survey has been carried out on 8 low to medium-rise RC residential buildings from Shahjalal Upashahar of Sylhet, Bangladesh to assess the earthquake vulnerability. The first level, out of the three levels of…
Improvement of the compressive strength of soft clayey soil using the bio-treatment method

Abstract : As environmental concerns, economic viability, and application practicability have grown in importance, the creation of novel methods to enhance the engineering qualities of soil has emerged as a new area of geotechnical engineering. Numerous techniques of soil improvement have been put forth in this respect in an effort to meet sustainability requirements, lower the overall cost of construction, and ensure safe field application. To fulfill these requirements, the Microbially Induced Calcite Precipitation (MICP) technique is now widely used. The objective…
Higher Order Statistical Analysis of Group Delay Spectrum for Formant Estimation of Noisy Speech Signal
Corresponding Author : Husne Ara Chowdhury (husna-cse@sust.edu)
Abstract :
The spectral distortion caused by different additive Gaussian noise degrades the speech quality. As a result, it imposes problems when estimating the formant frequency. In this paper, we proposed a technique for
estimating the formant frequencies from the noisy speech signal. A process is described to suppress the noise of the noise-perverted speech, employing the higher-order statistical (HOS) analysis. After analyzing a few issues related to the magnitude spectrum, we used a minimum phase signal to extract an efficient group delay…
Variation in biochemical composition and quality of commercially available green tea and black tea in Bangladesh
Corresponding Author : Mitu Samadder (msamadder-fet@sust.edu)
Abstract : <p>This study investigates the biochemical composition and quality attributes of commercially available black and green tea samples in Bangladesh. Ten popular tea brands, five each of black and green teas, were analyzed for various parameters including total polyphenol content, antioxidant activity, caffeine content, moisture content, lipid content, ash content, and water extract. The results revealed that green tea generally contains higher levels of polyphenols and exhibits greater antioxidant activity compared to black tea. Conversely, black tea samples showed higher caffeine…
Productivity Improvement Applying “Theory of Constraints” Approach – An in-depth case Study in An Agro-Processing Organization in Bangladesh
Corresponding Author : M. H. Kibria (kibria-ipe@sust.edu)
Abstract :
The Agro and Food processing industry is a rapidly growing sector in Bangladesh. It employs a significant portion of the labor force in the country. This sector exports many items, including processed food products such as frozen fish, shrimp, food in dry form, processed meat, ready-to-cook food like paratha, dal puri, etc., and earns considerable
foreign currency. It has indeed more potential to earn as global demand is upraising. To cope-up with competitive edges, the industry must increase productivity by ensuring…
