(Daffodil International University, 23-03-29) Shahiduzzaman, Md.
The internship program is a prerequisite for obtaining a Master of Business Administration (MBA) degree from Daffodil International University (DIU). All students are required to complete an internship program before graduation. In the modern business world, internships help students demonstrate their skills and abilities from supervised experience, and can also demonstrate academic learning and acceptable professional, personal, and interpersonal conduct. . It is an opportunity for students to know the actual situation through this program. This internship report is prepared on the basis of US Retirement Planning and Real Estate Valuation and Operations of Odin Offshore Sourcing in Bangladesh to meet the requirements of pursuing postgraduate studies in his MBA program at Daffodil International University (DIU) it was done. By completing this internship program, you will get to know the professional working environment. I He has been working for Odin Offshore Sourcing since December 1, 2021 as a Financial Analyst. From there, I gained a better understanding of key issues such as: B. Conducting Real Estate Appraisals and Reporting Rules and Regulations for American Retirement Benefit Plans. This report reflects my performance at the company based on about one year of professional experience.
Determinants of Health Condition and Estimation of Demographic Parameters of Street Children in Dhaka City, Bangladesh
(University of Rajshahi, Rajshahi, 2021) Shahiduzzaman, Md.; Islam, Md. Rafiqul; Ali, M. Korban; Islam, Md. Nurul
Health and demographic condition of street children are important issues for the development of any country. Several researchers estimated that a substantial percent of total street children in Bangladesh are living in the Capital City, Dhaka, Bangladesh. But no study is available which concentrated to in-depth study of health condition and estimation of demographic parameters for the street children. So the aim of this study is to identify the determinants of health condition and estimation of demographic parameters of street children in Dhaka city, Bangladesh. We have used convenient sampling for selection of samples. The data were collected from 1108 street children in different places of Dhaka City using a comprehensive questionnaire. In this study, x2 statistic was used to test the significance of the association between the dependent and independent variables of the street children. Binary logistic regression model was also employed to identify the effect of the some important independent variables on dependent variable. To have a smooth pattern of age 3 years moving average technique and "4253H twice" smoothing technique were applied in this study. It was found that among total sample data 84.9% were male and only 15.1 % were female. Age structure of street children followed a polynomial function of degree four. Probability of dying (qJ calculated for street Children showed an expected pattern. The migration rate from rural to urban of male street children was higher than that of female street children. Migration rate of street working children was the highest among four types of street children. Migration rate of street children of illiterate fathers was higher than that of street children of literate fathers. Migration rate of street children of illiterate mothers was higher than that of street children of literate mothers.
Navigating Challenges and Promises for Next-Generation CsPbIBr2 Perovskite Solar Cells: A Review
(Wiley, 2024-09) Aamir, Muhammad; Hossain, Mohammad Ismail; Akhtaruzzaman, Md.; Rafij, Junayed Hossain; Uddin, Jamal; Akhtar, Javeed; Amin, Nowshad; EL Ganaoui, Mohammad; Nunzi, Jean-Michel; Taima, Tetsuya; Shahiduzzaman, Md.
Given the increasing demand for electricity due to modernization and population growth, there is an urgent need to develop renewable energy conversion technologies such as photovoltaics. Among these technologies, CsPbIBr2, an all-inorganic lead halide-based perovskite, has shown promise due to its thermal stability, phase stability, and ease of fabrication. However, challenges remain, particularly in addressing device hysteresis and stability. Novel materials and optimized device designs could help overcome these challenges. This comprehensive review discusses strategies such as interface engineering, film quality improvement, compositional engineering, defect passivation, band alignments, and metal ion doping to enhance the performance of CsPbIBr2-based perovskite films and, in turn, their potential for photovoltaic applications.
Revealing the full potential of CsPbIBr2 perovskite solar cells: advancements towards enhanced performance
(Royal Society of Chemistry, 2024-06) Hossain, Mohammad Ismail; Shahiduzzaman, Md.; Rafij, Junayed Hossain; Tamang, Asman; Akhtaruzzaman, Md.; Hamad, Almohamadi; Uddin, Jamal; Amin, Nowshad; Nunzi, Jean-Michel; Taima, Tetsuya
Cesium lead iodide bromide (CsPbIBr2) perovskite solar cells (PSCs) have improved stability compared to other perovskite compositions. However, they still face significant challenges due to their poor photovoltaic performance parameters, which limit the devices’ power conversion efficiencies (PCEs). This study proposes a novel device design to tailor the potential of CsPbIBr2 PSCs by improving their optoelectronic properties. An advanced 3D multiphysics approach was rigorously used to investigate the optics and electrical properties of the proposed CsPbIBr2 PSCs. This approach combines finite-difference time-domain (FDTD) and finite element method (FEM) techniques with the particle swarm optimization (PSO) algorithm. The outcome from the adapted numerical approach is in good agreement with the experimental results. The optimized CsPbIBr2 PSC demonstrates a promising power conversion efficiency (PCE) of over 16.4%, associated VOC of 1.53 V, FF of 80.6%, and JSC of 13.4 mA cm2. Therefore, the potential of CsPbIBr2 perovskites could be further explored with continued research and development in material science and device physics.
Web Application Development in i2soft Technology Limited
(Daffodil International University, 2019-12-10) Shahiduzzaman, Md.
A temporary job on "Web Application Development," working with different web innovations and picking up information to build up a significant undertaking has been broadly talked about. Working with various tasks and an enormous group in the earth is entirely unexpected as we for the most part think. This report talked about the obligations of a web engineer or developer and the agreeable working methodology. Working involvement in JavaScript, PHP, and WordPress among various web innovation, for example, JS(AngularJS; ReactJS), PHP(Raw PHP), CMS(WordPress) was the topic of the exchange. Why helpful coordinated effort is tended to in the examination by actualizing a typical working model. There are numerous degrees of improvement of the undertaking. What layer I worked with has been tended to and my involvement in that layer. My work in the making of papers, online business and a lot progressively differing sites were tended to principally. Plan of frontend with a backend system and picking up information on being a full stack designer has been quickly tended to.
