(North South University, 2021) Asrafi Akter; Naziba Nasir; Saheeb Tareque; Mohammad Monirujjaman Khan; 1711502042; 1612618042; 1721809042
The deadly COVID-19 started its journey in December 2019 in China. For most of the patients, it’s like a mild fever and non-specific gastrointestinal symptoms to a lesser extent. Aged people with previous illnesses like diabetes, heart problems, and high blood pressure suffer the most. Until 26th May 2021, there have been 169,094,726 confirmed cases of COVID-19, including 3,512,510 deaths, reported to the World Health Organization. Since COVID-19, lifestyle has changed for almost everyone. That’s when e-learning had a bigger impact on all the students worldwide. It is no different for the students of Bangladesh, either. To keep the study of the students, the government of Bangladesh made a decision and advised the educational institutions to take classes online. While attending online classes, students are facing many opportunities and obstacles, such as disruption in class, health issues, financial issues, and saving time from traffic. However, being captive, they have utilized their time a lot better, and this has reflected on their performances too. Machine Learning is a sub-region of man-made reasoning, which predicts outcomes depending on the features of a given dataset. In this paper, with the help of a machine learning approach, 6 university students during the pandemic were found. By creating our dataset, the model was trained, and then a prediction was made depending on the different features of the dataset. The collection of data that helped to create a model and gave the highest accuracy over students’ performance. Exploration was done using different algorithms, i.e., Linear Discriminant Analysis (LDA), Logistic Regression, and K-Nearest Neighbor (KNN) for classification. Prediction score Accuracy of 81.05 % by LDA, 86.3% by Logistic Regression, and 84.2% by KNN was achieved. The highest prediction score was achieved by Logistic Regression (86.3%). The accuracy shows the effectiveness of online classes during the pandemic through a Machine Learning approach. It shows how the online classes are effective for a particular student when the input fields are filled. Overall, after performing the three algorithms (K-Nearest Neighbor, Logistic Regression, Linear Discriminant Analysis)with satisfactory results and successfully predicting with a high level of accuracy, while maintaining its objective of being easy to understand.

(North South University, 2021) Tareq Rahman; Mohammad Ali; Tahia Tasnim; Atiqur Rahman; 1611097042; 1612571042; 1811155042
We built a project that will improve hospital experience among patients, doctors, and hospital authorities. That’s why the name of our project is “E-Care Management System”. The entire system will be based on the Internet. People will be able to schedule appointments with doctors, obtain prescriptions, and seek advice from doctors through this website, and doctors will be able to communicate with patients. This project aims to create a general-purpose e-care system that will allow patients to get their preferred service during critical periods from the comfort of their own home over the Internet. Our project's key objectives are to administer the entire system and put hospital officials, doctors, and patients under one roof to make the system transparent and user-friendly[1].

Optical Pulling Force for Distinct Nanoparticle in a mixture of three nanoparticles
(North South University, 2020) Rahul Mahmud; Masud Rana; Mahdy Rahman Chowdhury; 1621204045; 1620161043
Every aspect of this world has become advanced in the last decade due to the development of science and technology. In our experiment, we have used three kinds of nanoparticles, such as Dielectric, Plasmonic(PEC), and Chiral. These nanoparticles are kept in a substrate whose surface is plasmonic(PEC). We are trying to obtain remarkable pulling force. We have used lights such as angles that can obtain pulling force. We have checked from 400 nm to 1800 nm to get better pulling forces. But in our experiment on a plasmonic substrate, we don’t obtain a good amount of pulling force. Most of the time, pulling forces are missing. So we are trying to find the reason why we don’t get optical pulling force. Our experiment will essentially help in medical uses in the future. If we can modify and implement beautifully, then it can be used widely in medical science. We can also use this force to increase the amount of electricity we use. So our experiment can help in our everyday life.

Metasurface “Solar Sail” For Flexible Motion Radiation Pressure Control
(North South University, 2020) Mohammad Sabbir Ahmed; Rifat Sarker APU; Mahdy Rahman Chowdhury; 1721550043; 1721186043
We analyzed the theoretical and experimental data of metasurface solar sails and their effect on the three forces (repulsive, attractive, lateral) applied to the sail. Our experiment goal is to control radiation pressure; the solar sail motion range will increase. In addition, we present mathematical analyses on different electromagnetic fields and make a balance with our experimental data. Using unusual optical reflections from metasurface to generate pure forces in the plane. Specifically, we design a new metasurface and experiment based on previous researchers’ theory and compare it with previous work. We also present mathematical synthesis and make configurations that allow for pushing and lateral movement for new metasurfaces.

THE CAUSAL RELATIONSHIP BETWEEN OIL PRICE AND INFLATION IN BANGLADESH: AN EMPIRICAL ANALYSIS
(North South University, 2022-12) Sakib Bin Amin; Maimaz Afiabi Atiqtee; Farheen Rishia Butte Benazirs; Helal Ahammad
Bangladesh is one of the fastest growing developing economies in the South Asian region with very little fossil fuel endowment. As a result, the country typically relies on imported energy sources. Existing media reports point out an increase in global energy prices in recent years. An increase in global oil price simultaneously increases the rate of inflation in the oil importing countries as well. Hence, the aim of this paper is to empirically analyze the short-run and long- run causal relationship between oil price in the international market and domestic inflation in Bangladesh. Using annual data ranging from 1980 to 2021, the paper conducts a Johansen's cointegration test to identify the variables' cointegrating relationship. Moreover, Granger Causality and VECM causality tests confirm a unidirectional causality runs from oil price in the international market to domestic inflation in Bangladesh. both in the short run and in the long run.

IMPACT OF ENERGY USE ON WOMEN EMPOWERMENT IN BANGLADESH: AN EMPIRICAL ANALYSIS
(North South University, 2022-12) Anta Atalantial; Sakib Bin Amin; Helal Ahammad
Bangladesh achieved significant progress in the energy sector from 2009 to 2019, and it has helped the country to improve the socio-economic conditions of women. However, to the best of our knowledge, there are no empirical time-series studies that explicitly address the relationship between electrification and women's empowerment. For an emerging country like Bangladesh, where women's work is often undervalued and society seems to be biased towards men, the demonstrated relationship between electrification and women's empowerment may have unveiled the immense impact that this might have had on the society. Hence, this paper investigates and quantifies the impact of electrification on women's empowerment, taking the general view that increasing electrification in Bangladesh results in empowering women in a community. Augmented Dickey-Fuller (ADF), Dickey-Fuller- GLS (DF-CLS), Johansen Cointegration methods have been used in this paper to explore this relationship. Moreover, the Granger-causality-test, Vector-Error-Correction Model (VECM) tests have also been applied to quantify this relationship. Our results support the view that energy use has a potential impact on the female laborforce in Bangladesh's both in the long and short run. Moreover, it also has a statistically significant effect on the female literacy rate in the long run. The Dynamic OLS (DOLS) results show that a 1-unit increase in energy consumption can lead to a 0.20 percent increase in female labor force participation in the long run other things remain unchanged. So, access to adequate electricity can provide the opportunity for employment creation to the poor female. To do so, the Bangladesh government should pay more attention to the development of off-grid electrification to better the socio-economic conditions of the unprivileged rural women in Bangladesh.

AN INVESTIGATION OF THE MODERATING EFFECT OF SELF-EFFICACY AND ALERTNESS ON REGULATIVE, COGNITIVE, AND NORMATIVE DETERMINANTS OF ENTREPRENEURIAL INTENTION
(North South University,, 2022-12) Md Reaz Uddinf; Md Shaifid Islam; Helal Ahammad
The purpose of this study is to investigate the relationship between institutional environment and entrepreneurial intentions and to determine whether self-efficacy and alertness moderate this relationship. Drawing on institutional theory, we set hypotheses and test them by applying regression based on a primary dataset of students collected from the local public and private universities. The results show that cognitive institutions positively influence entrepreneurial intentions; thus, they inspire students to set up more entrepreneurial minds. Furthermore, we find direct positive effects of entrepreneurial alertness and self-efficacy on entrepreneurial intentions. Still, we do not see any moderating (interaction) effects of the institutional environment on entrepreneurial intentions. The research results suggest that Bangladesh needs to develop cognitive institutions to encourage student& entrepreneurial intentions. Future research should be expanded for retesting the empirical validity of the included moderators by using longitudinal datasets.
