Corresponding Author : Md Mostafizur Rahman (mostafizur.cep@gmail.com)
Abstract :
This study highlights on synthesis of conductive polypyrrole (PPy) composites and application in the development of supercapacitor. PPy was synthesized using FeCl, as an oxidant in aqueous medium. Polypyrrole composite were synthesized with ZnSO,, NiCl,, MgCl,, Cuci, Sodium Dodecylbenzene Sulfonate (DBŞNa) in various compositions. The experimental result showed that the polypyrrole composite exhibited higher electrical conductivity compared to polypyrrole. Among Polypyrrole composite containing different inorganic and organic salts, DBSNa-PPy composite showed the highest electrical conductivity of 25 S/cm and capacitance…

Abstract : Replacing fossil fuel based energy by renewable energy is a crying need of the present world. Solar energy is one of the most popular and important sources of renewable energy. The geographical position and climatic conditions of Bangladesh are favorable for solar energy. The diurnal variation of solar irradiance is an important issue for all solar PV installations. In this research work, the solar irradiance at different tilting angles was measured during the sunshine hour. The daily data collection is…
Evaluation of a Sustainable Effluent Treatment Plant for Textile Industries
Corresponding Author : Muhammad Abdus Samad (samad-ipe@sust.edu)
Abstract :
Textile industries in Bangladesh produce a great amount of effluents, as a byproduct. Despite many regulations set by the DoE to make sure that the textile factories treat their effluents according to the quality standards, many of the existing textile factories do not follow it. Some of the main reasons for not following regulations include the lack of financial resources, and lack of knowledge, and lack of expertise in maintaining an effluent treatment plant. This work aims to provide a…
Company Readiness towards Green Manufacturing - A Case Study in Readymade Garments
Corresponding Author : Mst. Nasima Bagumn (nasima-ipe@sust.edu)
Abstract :
Green manufacturing processes mitigate environmental pollution, save energy and maximize resource efficiency. Nowadays, Readymade garments are showing increased attention in achieving Leadership in Energy & Environmental Design (LEED) certificate. However, LEED certification requires high initial investment and low profit at the initial stage. LEED comprises factors to alleviate energy and resource consumption in building design, transportation, and water usage. However, green manufacturing also requires criteria such as the participation of stakeholders, waste minimization in the production, sourcing and selling green…
Bangla Sign Language Alphabet Recognition Using Hand Gestures : A Deep Learning Approach
Corresponding Author : T. B. Das (taanmoycse15@gmail.com)
Abstract : Real-time recognition of Bangla Sign Language (BSL) alphabet using hand gestures is a fascinating research topic for image processing and computer vision enthusiasts. A significant amount of researches has been done on this topic recently. BSL is a blessing for deaf and mute people of the Bengali community around the world as it minimizes discomfort in their day-to-day lives. However, in most cases, people without disabilities do not know Bangla Sign Language, thus there is a huge barrier to communication…
Machine Learning Based Approaches for Recommending Colleges to HSC Appointees
Corresponding Author : M. Rahman (moqsad-cse@sust.edu)
Abstract : Getting admitted to a suitable college that provides quality higher education becomes the dream of every student after crossing the barrier of the Secondary School Certificate (SSC) exam. Insufficiency of proper quality institutions and the high increasing rate of candidates are the main challenges against the attainment of this dream. Mitigation of this challenge may be possible through a recommender system. Is there any possibility of a recommender system that will recommend suitable colleges to a higher secondary education appointee?…
Development of Aloe Vera Based Bio-preservatives and Their Effect on The Quality of Tomato (Lycopersicon esculentum) and Banana (Musa acuminata)
Corresponding Author : W. Zzaman (wahid-ttc@sust.edu)
Abstract : Bangladesh produces a huge amount of Banana (Musa acuminata species named Sagor) and Tomato (Lycopersicon esculentum) every year but the postharvest loss of this product is almost 35-40% due to lack of proper storage methods. The study aimed to develop an Aloe Vera based bio-preservative (Aloe Vera Gel) and Aloe Vera gel formulation with an organic acid and their effects on the quality of the samples were investigated. The fruit weight loss, titratable acidity, total soluble solids content (TSS), pH…

End-to-End Bengali Speech Recognition using DeepSpeech
Corresponding Author : M. M. H. Nahid (nahid-cse@sust.edu)
Abstract : One of the main challenges in Bengali speech recognition is modeling phoneme alignment. The exact prior probabilities of phoneme transitions in an individual word are not known; in this paper, we seek to investigate the DeepSpeech network for recognizing individual Bengali speech samples. There are recurrent LSTM layers at the heart of this network for modeling internal phoneme representation. We have added convolutional layers at the bottom which obviates the need of assuming anything about internal phoneme alignment. We have…
