Techno‑Economic Analysis of Off-Grid and Grid-Connected Solar PV Systems for an University Building
Corresponding Author : Muhammad Mahamood Hasan (muhammad.hasan-ipe@sust.edu)
Abstract : To meet daily energy demands, the world depletes all natural resources, especially fossil fuels, resulting in rapid depletion of natural fuel reserves and irreversible environmental damage. In today's world, there is an urgent need to replace fossil fuel-derived energy with renewable energy. Solar energy, as an inexhaustible and abundant renewable energy source, is gaining popularity worldwide, including in Bangladesh, due to its geographical location and climate. The current research project aims to design photovoltaic (PV) energy systems, including grid-connected and…
Group Delay Moment of Cepstrum for Formant Estimation of High-Pitched Noisy Speech
Corresponding Author : Husne Ara Chowdhury (husna-cse@sust.edu)
Abstract :
The estimation task of formant frequencies is challenging for some spectral estimation issues. However, it is significant in the female or child speech-processing arena. This paper proposes a method for calculating the formant frequencies of high-pitched speech employing third-order group delay moment (GDM) of cepstrum. The GDM is a time domain equivalent signal estimated using the inverse discrete Fourier transform (DFT) of group delay spectrum (GDS). The GDS is calculated from the cepstrum. The stabilized spectral root cepstrum (SRC)…
Investigation on opacity of gaseous stars
Corresponding Author : Syed Badiuzzaman Faruque (awsbf62@yahoo.com)
Abstract :
Following Sir A.S. Eddington’s work on the interior of gaseous stars, we derive a simple equation that gives opacity of a star which depends on the mass of the star and another stellar parameter. We compare our result with the existing result of Kramer. We conclude that massive gaseous stars have lower density and higher temperature than low mass gaseous stars.
Microcontroller based Digital System for Monitoring and Analyzing Seismic Activity

Abstract :
An earthquake is a devastating natural disaster that can have a significant negative impact on our civilization. To decrease the damage from an earthquake and save several lives, we need to gather deep knowledge about seismicity and develop a seismic activity analyzer to record the ground motion caused by an earthquake. This article presents the development method of an Arduino-based low-cost electric device that can be constructed easily to detect and graphically present any seismic activity with a warning…
An Analysis of Seismic Risk for the Building Stocks in the Sylhet City Corporation, Sylhet, Bangladesh: A Case Study on Ward No. 1
Corresponding Author : Najmul Kabir (n.kabir-gee@sust.edu)
Abstract :
Bangladesh is one of the most earthquake-prone countries in the world because of the difference in energy between the Indian and Burma plates. Frequent earthquakes could lead to massive loss of property and destruction. This study aims to determine the seismic risk of building stocks in Sylhet City Corporation (SCC). Amongst 28 wards, Ward No. 1 was selected, as it is one of the preferable residential areas and has almost 2143 buildings. By following Sloven’s formula (1960), 320 buildings…
