Effective placement of fluid viscous damper in irregular shaped reinforced concrete buildings
Corresponding Author : N. Ahmed (nirob.cee@gmail.com)
Abstract :
Damping has a significant task to diminish the reaction of the structures when exposed to sidelong loads like earthquake loads. There are a few kinds of dampers being used. Among them, Fluid Viscous Dampers (FVD500) is used in this study to evaluate the response of irregular shaped reinforced concrete buildings. Four types of buildings having plan irregularities, namely Box Shaped Building, C Shaped Building, I Shaped Building, and L Shaped Building, are analyzed with FVD500 at the Corners and Exterior…

Abstract :
Bangladesh is one of the most tectonically active regions in the world. It rests where three tectonic plates meet. Recent occurrences of several frequent minor tremors indicate that Bangladesh is at high risk of a devastating earthquake. Most of the buildings in Bangladesh are not constructed following current building codes and in the majority, seismic behavior is not taken into consideration. So, it has become quite vital to quantify earthquake risks and to develop a strategy that will be followed…

Abstract :
Nowadays, while the globe is facing extreme difficulty with COVID-19, Artificial Intelligence can help to cope with this epidemic in an innumerable number of ways. Motivated by this, in this article, a robust prediction model has been proposed for pandemic COVID-19 using Sequential Deep Learning (SDL), called COVID-SDL to predict the total positive cases. The proposed model utilizes the correlation information among the features that have strengthened the prediction capability. In addition, to assist the prediction ability of COVID-SDL, ReLu…
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

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…
