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…

Abstract : Heavy metal pollution and its effects on public health and the environment have led to an increased interest in developing biotechnological approaches. This study was carried out to check the heavy metal biosorption capacity of locally available blue-green microalgae. In this study, microalgae were collected from local ponds and cultured in BG-11 medium. Sixteen different algal doses from 0.2 g/L to 20 g/L were applied to synthetic wastewater and their removal efficiencies of Cr(VI), Ni(II) and Zn(II) were found to…
Estimation of Water Quality in Surma River Using Digital Image Data

Abstract : Typical water quality measuring techniques in Bangladesh are time-consuming, costly, and are not certainly accessible to the general people while it is very essential for ensuring safe water for different household and drinking purposes. In this study, a low-cost digital camera has been used to measure different water quality parameters aimed to shape it as an alternative to the traditional system. Water samples were collected from two points of the Surma River, and subsequent images were taken with camera height…
A Study on the Efficiency of Permeable Concrete with Scrap Tire Rubber
Corresponding Author : M.I. Kabir (imran.kabir-cee@sust.edu)
Abstract : With the advancement of civilization, the volume of polymeric wastes, for example, tire rubber is expanding at a quick rate. This study attempts to utilize this discarded tire rubber to produce permeable concrete for stormwater management in urban area facilitating water sensitive urban design and to compare it with the conventional permeable concrete. In this study, 5%, 10% and 15% coarse aggregate are replaced with shredded tire rubber (as w/w ratio) maintaining a constant water cement ratio of 0.32. It…
Rethinking Urban Retail Spaces due to Covid-19 Pandemic in the context of Sylhet, Bangladesh

Abstract :
Maintaining social distancing is currently an ultimate prerequisite to evade the crowd owing to the Covid-19 pandemic in public spaces like marketplaces, retail shops, parks, and streets. Adopting social distancing is quite thought-provoking mostly in public buildings in Bangladesh since the building design concept allure public gathering, more accessibility, and shared facility. Retail spaces like markets and shopping malls are one of the centers of public crowds where people commonly share facilities and circulation significantly. Apart from social distancing, there…
Evaluate Bearing Capacity of Fixed Type Sand Compaction Pile (SCP) in Clay with the Variation of Clear Distance between Two Successive Piles
Corresponding Author : Md. Foisal Haque (mfh.civil@gmail.com)
Abstract :
Sand compaction pile (SCP) is the economic and less time-consuming technique of ground improvement for most of the countries concerning other piling methods based on the historical data and it is used for the replacement of cast-in-situ, precast, timber, and composite piles. The installation method of SCP is easier and faster than other methods because of less unit weight and no additional materials are inserted during construction. Square patterns of SCP are most suitable and easier to construct than others…

Abstract : The rate at which COVID-19 has rapidly been spreading has made every sector of human life to feel its impact immediately. Like adults, children are also suffering heavily since the outbreak of Covid-19. The education institutes in most parts of the world have been closed since last week of March, 2020. When the school break became longer, new online learning policies were taken and most of the students around the globe started to attend online classes. Children have started to…
Dimension Reduction Using Supervised LDA and Unsupervised PCA and 3D CNN for Classification of Hyperspectral Image
Corresponding Author : T. Jannat (jannat22tasmia@gmail.com)
Abstract : Hyperspectral Image (HSI) classification is becoming extremely appealing now-a-days because it contains huge information about a scene. The main problem of dealing with hyperspectral image is “Hughes Phenomenon” caused by the large number of dimensions. To address this, dimensionality reduction techniques need to be applied as a preprocessing step. In this paper, we used supervised LDA and unsupervised PCA for dimension reduction. Then for classification we used 3D CNN. Performance of classification depends on both spatial and spectral information for…

Abstract :
As the world population is growing fast, the demand for electricity in our daily life is also increasing rapidly. To meet the high demand and fight against global warming worldwide, use of renewable energy sources seems the inevitable choice. In the last few decades, the use of renewable energy has increased immensely. Our country is not an exception to that. Though the government has taken many initiatives to send electricity to the most remote corners of the country, yet due…
Effect of Blanching Pre-Treatment and Drying Temperature on Drying Kinetics and Quality Characteristics of Mango Peel Powder
Corresponding Author : M.S. Hossain (sajjad.bau@gmail.com)
Abstract : <p>Mango is a seasonal nutritious fruit as it generates mango peel as a byproduct from the mango processing industries in a huge amount. The effect of pretreatment (hot water blanching & steam blanching) and drying temperatures (60°C, 65°C, 70°C) by convective drying on drying kinetics of mango peel and sensory properties of dried mango peel powder (MPP) were evaluated. Increasing Drying rate and decreasing drying time were observed by increasing the drying temperature. The maximum drying rate was observed for…
