Analysis of Loan & Advances on Bank Asia Limited
(Daffodil International University, 2020-10-03) Anisur Rahman
This notice is subject to lending rates and advance payment to Bank Asia Limited, Savar branch. Through this report, the reader will be able to learn about the current state of the loan and about the forthcoming branch of Asia Limited in Savar. This report also describes the different types of loans that they offer to their clients and the different treatments that lead to different types of loans. This article will provide readers with more information about the various divisions of Bank Asia Limited, the branches in Savar and how they do their job. The two branches of the branch are described in detail. First the report will tell the reader about the banking institution of the branch, which is to give the reader the importance of the general banking process and then the people. Use business products that banks provide, for example, savings accounts, accounts, pension plans, fixed deposits and more. Second, the reader will be familiar with the credit lending process based on its product portfolio like its loans, home finances, fixed assets, unsecured loans and other and last but last but not least, the reader will be able to understand the effectiveness of all organizations in the market, even if the financial analysis (return on fairness, part income, return on assets,etc.
Detection of control loop interaction and prioritization of loop maintenance
(Department of Chemical Engineering (Ch.E), 2011-03) Anisur Rahman; Choudhury, Dr. Md. Ali Ahammad Shoukat
In automatic control system of a chemical process, tens or hundreds of control loops are used in a multiloop control con guration. Loop interaction arises in these loops when changes are made in one of the parameters of the control loops. It is di cult to measure the degree of interactions between the control loops and rank the loops according to their extent of interactions. This study presents two novel data driven techniques to determine control loop interactions and rank the loops according to their importance. In rst approach, two new indices have been developed using integral of absolute or squared error (IAE or ISE) criteria to quantify loop interaction and determine rank of the loops. The rst index calculate the presence of interaction from one loop to another using IAE or ISE of the two interacting loops. Then by using these loop interaction values a loop interaction matrix has been formed. The second index uses the loop interaction matrix to calculate the rank of the loops. In another approach, a novel method based on canonical correlation analysis has been developed to calculate interaction among the loops. An index has been proposed in this method to determine the ranking of the loops and the ranking has been done with respect to the maximum canonical correlation value of the control loops. The proposed methods have been evaluated using both simulation and experimental studies. Both simulation and experimental results demonstrate the validity and e cacy of the proposed methods.
Electricity generation using gravity and buoyancy force
(North South University, 0000) Amena Akter Sumona; Abdullah Al Noman; Anisur Rahman; Shah Sadad Ahmed Nabil; Zunayeed Bin Zahir
The consumer of electricity is increasing day by day due to many domestic and convenient electric devices like TV, fridge, lift etc. As a result, production of electricity has also increased over the years. Patrol, gas, coal etc are used to produce electricity, which causes environmental pollutions and global warming. If that goes on for too long, there will be a time when the earth may need to face the scarcity of all those resources in the near future. Consequently, there is a huge need for producing power from renewable sources. The reason for choosing gravity is that it is available everywhere on Earth and it does not diminish. In this project we present an electrical generator, which will be powered by gravitational and buoyancy force. The generator is divided in two parts, the mechanical domain and the electrical domain.
Performance evaluation of shading devices used in tall office buildings of Dhaka city
(Department of Architecture, BUET, 2007-05) Anisur Rahman; Ahamed, Dr. Khnndaker Shabbir
One of the characteristics of to.lloffice building:; in nhah city i< the extensive uoe of glazing on d,e bwlding facades. This inct~a,ing U3e of glaS3 has cau3ed con:;iderable changes in the relation3hip b~tv.'een interior and ambient dimate, where the problem of overheating ha3 become a major concern. So facades of tall building< need protection from soJar heat gam to achieve desitable indoor env;ron.meot and to reduce the enetgy consumption ill the building" by the air conditioning "ystem. External shading devices c.~n be utili,ed to block the ,olar rac.ltltion before it teaches the window surface and hence more effective than intetrull shading deviccs. The ptoblem was approached by performance evaluation of sclccted commonly used shadIng devices of tall office buildings through simulation study_ Shadow simulation alIo", stud)' of the effect of changes in one aspect, keeping other factots con,tant. The observations of simulated performancc that occurs due to changing parametcrs allow the identifiotion of elements, the reduction or introduction of which in the design contnbute to solar heat gain. Through simulation study, it is possible 10 analyse the performance of shading devic~' for any period of the yeat. The simulation .luille. were conducted fot the months from March to September repcc.enring hot-dry and warmhumid period, which is mo,t .ignificant in term. of dimatic severity.
