A Comparative Study on Blockchain Based Banking Sector
(Daffodil International University, 2020-10-26) Imran, Md. Al; Gupta, Prithula; Rana, Md. Juyel
The banking sector is arguably the most important sector of any country. While all other losses from different sectors can be compensated, normally the losses in the banking sector are so high that it devastates the country’s economy. Now, there are many reasons behind the losses of the banking sector, ranging from transparency issues, inefficiency issues to maintenance issues. All these issues make the banking sector vulnerable to the attacks of criminals. As a result, we have seen different crimes happening in banking sector such as money laundering, cyber-attacks etc. The biggest worry is that these crimes make really big losses in the country’s economy. As a result, to make the banking sector resilient against such things, blockchain technology is a potential solution. Blockchain technology offers a very secure method for transactions. The combined use of smart contract & blockchain makes it really hard for cyber attackers to penetrate into the system. It also allows a better monitoring system for the banking authority. As a result, the total maintenance system becomes easy. It also provides the system with other benefits like cost reduction & time waste reduction. In this writing, We will try to build such a blockchain-based banking sector which will have all the tools to replace the current banking sector.
Castep-Based First-Principles Study Of The Electronic Structure And Properties Of α-Ga2O3
(Daffodil International University, 2025-09-25) Akheruzzaman, Md.; Imran, Md. Al; Shekh, Md. Alauddin
Gallium oxide (Ga2O3 )is a wide-band semiconductor. Applications include power electronics, photodetectors and solar cells, among others. Gallium oxide (Ga2O3) is generally a typical n-type conduction mineral and so far it is very difficult to obtain stable p-type conduction. A great deal of work has been devoted to enhancing the p- type behavior of Ga2O3, particularly in the monoclinic β-Ga2O3 phase, by introducing metals such as Ca, Zn, and Cu. This research work mainly but not completely comes to the existence of very few theoretical work on the electrical band structure and other properties of doped allotrope α-Ga2O3. We investigate Cu-doped α-Ga2O3 with first- principles calculations in this paper. We optimized the geometry using the CASTEP calculation approach and the Perdew-Burke-Ernzerhof (PBE) functional of the Generalized Gradient Approximation (GGA). We are particularly interested in understanding the band structure, density of states (DOS), and optical properties of Cu- doped α-Ga2O3. All simulations were performed using Materials Studio, a software specifically designed for modeling and simulating materials. In this study, we would like to know how p-type conductivity occurs in α-Ga. We hope our findings will lead others to consider how to develop new semiconductor devices using α-Ga2O3.
Smart Tourism Bangladesh
(Daffodil International University, 2018-12-26) Khan, Md. Tazul Islam; Islam, Md. Ariful; Islam, Nourin; Imran, Md. Al
Nowadays a smartphone user always looks for an android application for his daily need. Android makes it easier for people to use new applications on their device. Now the development of worldwide travel has been more outstanding and perfect. It is very important to offer travelers an outstanding travel platform. This project is to produce a travel guide for the whole of Bangladesh which can efficiently guide the travelers who visit this country. The aim of this project is to explore the requirements of tourists in Bangladesh and developed the solution of android application including some basic guidance for the travelers of the whole of Bangladesh. Every year thousands of tourists from different countries come to Bangladesh for traveling purposes. ―Smart Tourism Bangladesh‖ is also for native tourists who use Android-operated smartphones. This application has some advanced features for tourist to simplify their trip. This application helps a tourist as their guide and it contains lots of tourist spot information with their location, direction, and route. Traveler or tourist can use this app easily in their Android smartphones. This application provides a fast, simple, efficient and high-quality performance to the users.
