A comparative study on machine learning algorithms for improved prediction measures for COVID-19
(International Islamic University Chittagong, 2022-02) Rahman, Md. Ziaur
The Corona-virus (COVID-19) is an emerging disease responsible for infecting millions of people since the first notification until nowadays. Corona virus causes respiratory ailment like influenza with symptoms for example, cold, coughs, fatigue, fever and gradually increases the breathing problem. The disease and symptoms are changing frequently thus due to time constraints it is literally impossible to test. Analysis of Covid-19 data using machine learning paradigm is becoming a major interest of the researchers in this situation. The aim of this study is to develop a better predicting model for Covid-19 patients. Patients feature can be assessed statistically and traditionally. But with this day and age of advanced machine learning approaches Covid-19 can be predicted using machine learning techniques with better accuracy. In this work four well known machine learning approaches was used for better prediction in Covid-19. However, this study focuses on optimizing machine learning approaches. Two optimization approaches employed for Grid Search and Random Search are used for fine tune in prediction.
A geometrical feature-based framework for pedestrian crossing recognition
(International Islamic University Chittagong, 2023-07) Md. Khaliluzzaman
In this work, a framework for the recognition of pedestrian crossing (PC) regions based on geometrical features is proposed. A distinctive feature of a pedestrian crossing (PC) is that each end point of the horizontal strip edges at pedestrian crossings intersects with a vertical stripe width edge, which comprises two connected points (2CP). Another unique feature of PC is that the PC stripe's edges are formed in ascending parallel order. These two features are utilized to identify the PC candidate region in the PC image. Where the 2CP and parallel edge segment in sorted order is used to validate and justify the PC region. Finally, classifier support vector machine (SVM) confirms the potential PC region. Here, the features of the candidate area are extracted using the uniform rotationally invariant Local Binary Pattern (LBP). The proposed framework is tested with our own dataset, and the results reveal significant improvement over previous work.
A review of β-caryophyllene oxide for its pharmacological properties supported by in silico findings
(International Islamic University Chittagong, 2022-12) Kamal, A.T.M. Mostafa
Bicyclic sesquiterpene, β-caryophyllene oxide (BCO) is one of the major components of essential oil derived from aromatic plants. It is reported to possess several interesting pharmacological prospects. BCO’s ability to suppress a few signaling cascades and down regulating various gene products responsible for cancer development against several cancer cell lines was seen along with some analgesic properties. Besides, its interaction with enzymes responsible for metabolism of the drugs performed in-vitro and in-vivo was found to show diminishing and enhancing effects on the enzymes. All the possible relevant published articles on BCO were collected using some popular search engines such as Google Scholar, Pubmed, ScienceDirect etc. The molecular docking was carried out with the help of Schrodinger Suites-Maestro 2017-1. In addition, the in-silico findings also provided strong evidence in favor of BCO with the ability to be a prospective therapeutic agent. However, from all the information gathered on this compound and clinical trials, this compound may yield beneficial results novel drug discovery.
A statistical analysis of the relationship between working capital management and profitability: Evidence from selected manufacturing companies of Bangladesh
(International Islamic University Chittagong, 2021-12) Hossain, Mohammad Emdad
The aim of this study is to measure the relationship between working capital management and profitability. The research is based on secondary data derived from annual reports of companies listed on Bangladeshi stock exchanges. The sample spans nine years, from 2011 to 2019, and includes 52 manufacturing enterprises in Bangladesh, including 20 pharmaceutical companies and 32 textile companies. The cash conversion cycle is significantly positively associated with profitability, the average collection period is significantly negatively associated with profitability, and the inventory conversion period is also significantly negatively associated with profitability, but the average payable period is not significantly associated with profitability. This research adds to the literature by focusing on working capital management and profitability, particularly in the textile and pharmaceutical industries. There have been a few research on this topic, however they are limited in sample size and time period. This research looks at all active businesses in these two industries. As a result, policymakers in these disciplines may utilize these findings to make decisions.
A study of in-vivo antidepressant, antidiarrheal and ex-vivo thrombolytic activities of methanol extract of Mikania micrantha leaves
(International Islamic University Chittagong, 2023-07) Ali, Md. Hazrat
Mikania micrantha (Asteraceae) has useful properties in the field of medicine. This study is aimed to elucidate the therapeutic potential of crude methanol extract of Mikania micrantha (MEMM) leave, on Swiss mice. The tests for antidepression potential were carried out using the model of both in-vivo forced swimming test (FST) and tail suspension test (TST). Again, the anti-diarrheal efficiency was carried out through the castor oil-induced diarrheal model; the clot-lytic property was investigated by thrombus dissolution property. The test samples showed dose¬dependent (200 mg/kg BW, 400 mg/kg BW) potentiality in antidepressant, anti-diarrheal and thrombolytic activities. MEMM demonstrated a significant increase in swimming tone and mobility in FST and TST. MEMM 400 (mg/kg; b.w.; p.o.) exhibited a significant reduction of diarrhoea over 4 hours. Besides, MEMM produced promising (400 (mg/kg; b.w.; p.o) 43.76 %) clot lysis activity. The observed results of this scientific investigation revealed the possibility of the suitable use of this plant and whether this plant is useful as a source of alternative medicine and new therapeutics.
A woman empowered with the power of love: A study of Alu in ¬e Swamp Dwellers by Wole Soyinka
(International Islamic University Chittagong, 2022-12) Uddin, Md. Abu Saleh Nizam
The Swamp Dwellers by Wole Soyinka (born, 1934) is mostly discussed for the emphasis it puts on the strong family ties felt by all the characters, presence of the elements of the absurd drama, corruption by the priests and human-nature relationship. But the powerful character Alu is also an area to concentrate on. She is a powerful woman with the power of love. This virtue of love she receives from her instinct, and her African tradition turns her into a powerful woman. Thus empowered, she plays her role in family, society, religion and nature. In the modern world where utmost cruelty looms large everywhere, love-empowered Alu is an example for positive change. Thus, this paper aims at exploring how Alu in The Swamp Dwellers is an empowered woman with love, who simultaneously receives her rights and does her duties in family and society, and nurtures deep feeling for religion and nature, and becomes an example to inspire humanity in a world of human catastrophes.
Accounting in Islamic Perspective: A Timely Opportunity, a Timely Challenge
(CRP, International Islamic University Chittagong, Bangladesh, 2012-12) Ahmed, Alim Al Ayub; Billah, Arif; Islam, Md Alidul
Accounting from Islamic Perspectives (AIP) is an emerging field. Recent years have attracted scholars from around the world who have contributed their thoughts about how accounting can be seen from the Islamic lens. However, the efforts so far are rather fragmented and without a clear agenda for future research. This paper presents a review of the literary achievements made in the field and the areas of current focus. Although the field carries a huge growth potential, the author argues that there are several challenges and problems that the proponents of AIP will face as the field develops further. This paper outlines these problems and challenges and makes suggestions to surmount the potential pitfalls. It is argued herein that, in order to develop AIP as a formal discipline and integrate it within real-life business practices, the research efforts need to be more organized through an international consortium of researchers. A brief proposal for such consortium is included here. Finally, recommendations are made for potential research directions in which future research on AIP can be pursued.

The Advent of Islam in Bengal; An Economic Perspective
(CRP, International Islamic University Chittagong, Bangladesh, 2010-12) Islam, Md Thowhidul
This article aims at examining the causes to the advent of Islam in Bengal with a view to identify the economic perspectives in particular. Islam took about six hundred years for its advent into Bengal with political conquest by Bakhtiyar Khalji in the early 13th century, while it had come to Arabia at the beginning of the 7th century. But long before the conquest of Bengal by Bakhtiyar Khalji, the Arab traders had established commercial relation with the coastal lands of Bengal. Islam began to enter into Bengal with the hands of these early Arab Muslim traders. With the beginning of this early advent, Islam started to enter into Bengal through both the sea and land routes on different circumstances. Though there were many other reasons and grounds for the advent of Islam in Bengal, but the economic perspectives were the foremost and forerunner of the causes.
Alison Porter in Look Back in Anger: Is She Responsible for her Sufferings?
(CRP, International Islamic University Chittagong, Bangladesh, 2014-12) Haque*, Salma
John Osborne’s play Look Back in Anger is a dramatic study of a strained marriage relationship. In it Jimmy Porter is the protagonist and Alison Porter, a retired Colonel’s daughter, is the heroine. The actual action of the play is centered around Jimmy’s relationship with her. Despite his dominance, his wife Alison Porter, is the most important supporting character on whom Jimmy inflicts pain by his tirades all the time until eventually she feels she can bear no more. Later on she leaves him in her pregnant state to seek peace. After the loss of the baby she comes back to him when both have lost faith in each other. So they will go back to their previous unhealthy relationship causing her to become deplorable again. My reading of Alison Porter is that she is a suffering person though some find Jimmy a sufferer. This paper aims at assessing her sufferings and the reasons behind them
Alternative Dispute Resolution (ADR) in the Administration of Civil Justice: Law and Practice in Bangladesh
(CRP, International Islamic University Chittagong, 2008-12) Hossain, Jahangir
The ADR system has been introduced and developed in the administration of civil justice in order to eliminate the endless suffering of the litigants. In most cases, the ever mounting expenses of litigation, congested court schedules, delay in disposal of suits have battered' the confidence of the people in the administration of civil justice and have put question on the efficacy of the system. The common forms of ADR are negotiation, conciliation, mediation and arbitration. All these various forms have some different characteristics but the ultimate goals of those forms are to relieve court backlog, undue cost and delay and to provide more effective, efficient and satisfactory dispute resolution to improve the quality of justice. This article is aimed at scrutinizing the mechanisms of ADR, incorporating in the provisions of different laws in Bangladesh and it's success. This article recommends for strengthening ADR mechanisms in the administration of civil justice and encourages litigants to resolve dispute through the mechanisms of ADR for establishing justice amicable settlement in the true sense.
Ambivalence: The Divided Selfin Sylvia Plath’s Poetry
(CRP, International Islamic University Chittagong, Bangladesh, 2006-12) Sharif, Mohd.Yasin
Ambivalence, mixed good and bad feelings about particular entity, individual or circumstance, became a ruling passion in Sylvia Plath’s life. These ambivalence and breakdown are closely dealt with in her poems. Confessional poets usually reveal their own personal experiences without straining excruciating sentiment. Sylvia Plath, one of the 1960s most influential confessional poets used the same resentment and anguish that developed from her personal grief as the subject of many of her poems. SP is well known among the celebrities for her ambivalence schizophrenic, schizoid and paranoid nature. As an obsessive-compulsive neurotic, ambivalence dominated both her works as well as her life. This ambivalent personality of SP made her and her works obscure and bizarre to the readers. Many of her poems bear the evidence of narcissism, self-hatred, deep attachment and simultaneously deep hatred towards her dear and near ones. The present study is an endeavor to interpret this complex ambivalent personality of SP in light of her poems, her journals and her letters where she clearly confesses all her neurotic obsessed activities directly, honestly and sincerely without any hesitation. The study will also dug out the true logical reasons that lead to the suicide of a blooming star in her makeup.
An effective and efficient protocol for propagating large files in Peer-to-Peer systems
(International Islamic University Chittagong, 2023-12) Hoque, MD Jiabul
Distributed Hash Tables (DHTs) are integral components in peer-to-peer systems, providing storage and lookup services for key-value pairs. While they have proven highly successful in managing and locating replicas of small files (typically under 1 MB), their efficiency in handling larger files diminishes. Factors like sluggish data senders and slow receivers further exacerbate the inefficiencies in peer-to-peer systems, causing delays in the file propagation process. To address these challenges, peer-to-peer systems require more efficient protocols and resources to expedite the handling of relatively large data files. This study introduces a novel, efficient, and effective mechanism to propagate substantial files within DHTs while balancing load and minimizing system overhead. To assess the proposed protocol's effectiveness, we evaluated using the PeerSim simulator. We analyzed two crucial metrics linked to our proposed system: overhead and propagation time. The outcomes of this research demonstrate a significant reduction in propagation time while system overhead remains minimal. Consequently, the proposed protocol can ensure seamless operation in real-world streaming applications.
Analysis of Retail Investors' Behavior in the Capital Market
(CRP (International Islamic University Chittagong), 2014-06) Islam, Serajul; Hoque, Nazamul; Hassan, Rizwan
There are various types of investors in the capital market, but retail investors are a mentionable portion and they behave in the market in different ways. They are of different age, sex, education background and size of the family. They are different on the basis of income level also. Investors' behavior is influenced by demographic, financial and macro factors. This paper examines the various influencing factors of behavior and thereby finds some motivating factors for which investors behave aggressively, moderately and conservatively in the market. Due to imbalanced behavior by some investors, the market price fluctuates extremely. As a result new investors sometimes lose their capital and that is de-motivational for the new as well as potential investors. So the paper is an attempt to study the investors' behavior for finding relevantfactors to control the market behavior that will protect the investors' interest as well as to develop the efficient capital market.
Antecedents, focus, and outcomes of work-life balance: A conceptual review
(CRP, Center for Research and Publication, 2020-12) Uddin, Mahi
Grounded on a thorough literature review, this study proposes a conception about work-life balance (WLB) in an integrated approach, which includes antecedents, focus and outcomes of work-life interface. This framework includes two essential aspects such as, commitment to work and non-work roles and minimum role conflicts between role domains of work and non-work. Based on our conceptualization, this study reviews evidence regarding the consequences of WLB relating to work, personal life and stress outcomes. The study finally reviewed 57 published articles in their entirety out of 181 articles selected through searching databases. The study then pinpoints organizational and personal predictors to WLB and describes their influences on WLB. After that, I explained relevant theoretical approaches are aligning WLB and life satisfaction. The findings explored two key predictors such as organizational and individual, and three key consequences including, work-related, non-work-related, and stress-related consequences. The study further explained several theories relating to WLB and life satisfaction. Finally, I highlight policy implications and directions for future research.

(CRP, International Islamic University Chittagong, Bangladesh, 2017-06) Sayeed, Mohammed Abu; Hossen, Altaf; Saha, Repon; Jakaria, Md.
The study was aimed to finding the antimicrobial activities among probiotics isolated from different yoghurts and their metabolites against some common bacterial pathogens. The nutrient agar media overlay method (Disc diffusion Method) was used to determine the presence of antibacterial effects among the isolated probiotics. Probiotics produced potential antibacterial activities against several pathogenic bacteria and fungi. The maximum antibacterial property (13.5 mm of zone of inhibition) of bacterial strain found against Salmonella paratyphi. Conversly, bacterial metabolites produced maximum effect (10.3 mm of zone of inhibition) against Staphylocuccos aureaus. The antibacterial effect is one of the most important criteria for probiotics selection, and the verified antibacterial activities of the probiotics supports the development of these functional foods as a key to the enhancement of health in the consuming public.
