    Assessing Lake Water Quality During COVID-19 Era Using Geospatial Techniques and Artificial Neural Network Model
    (Springer, 2023-04-24) Mohinuddin, S.K.; Sengupta, Soumita; Sarkar, Biplab; Saha, Ujwal Deep; Islam, Aznarul; Islam, Abu Reza Md Towfiqul; Hossain, Zakir Md; Mahammad, Sadik; Ahamed, Taushik; Mondal, Raju; Zhang, Wanchang; Basra, Aimun
    The present study evaluates the impact of the COVID-19 lockdown on the water quality of a tropical lake (East Kolkata Wetland or EKW, India) along with seasonal change using Landsat 8 and 9 images of the Google Earth Engine (GEE) cloud computing platform. The research focuses on detecting, monitoring, and predicting water quality in the EKW region using eight parameters—normalized suspended material index (NSMI), suspended particular matter (SPM), total phosphorus (TP), electrical conductivity (EC), chlorophyll-α, floating algae index (FAI), turbidity, Secchi disk depth (SDD), and two water quality indices such as Carlson tropic state index (CTSI) and entropy‑weighted water quality index (EWQI). The results demonstrate that SPM, turbidity, EC, TP, and SDD improved while the FAI and chlorophyll-α increased during the lockdown period due to the stagnation of water as well as a reduction in industrial and anthropogenic pollution. Moreover, the prediction of EWQI using an artificial neural network indicates that the overall water quality will improve more if the lockdown period is sustained for another 3 years. The outcomes of the study will help the stakeholders develop effective regulations and strategies for the timely restoration of lake water quality.

    E-Commerce Based Internship Report
    (Daffodil International University, 2018-12) Mondal, Raju
    This Internship report is for completion of my B.Sc. at Daffodil International University in computer science, aimed to improve and use the acquired knowledge during my studies. Providing Internship with a real work is number one to ensuring program’s success. Internship should be doing work related to their major, that is challenging, that is recognized by the organization as valuable and that fills the entire work term. For this I had internship over “E-Commerce Based web design” at a software company named Sumtech IT Institute. That company provides all quality assured IT services Web Development, Mobile Apps Development, Graphics Design and Ecommerce Solution. I have joined in Sumtech IT Institute. There I had many responsibilities like installing and configuring XAMPP server, website design and development like as HTML, CSS, PHP, Bootstrap-Framework, Query, JavaScript, PSD to HTML,testing the different browsers. In this internship report I basically tried to show that how I managed those things and how efficient I was there in the time of internship. Moreover, I tried to present whether my internship was a successful or not.Taking care of genuine issues was another key issue. This report takes me through all the details of every knowledge and experience gathered during this internship period. Finally I have created a small information site.
