    A domain and noise adversarial bird tune classification pipeline using deep neural network
    (BRAC University, 9/29/2022) Riya, Aparna Sarker; Roy, Arpita; Fahim, Md. Abrar; Tasnim, Zarin; Islam, Rakibul; Mostakim, Moin; Reza, Md Tanzim
    Birds are an important category of animals that ecologists keep track of utilizing autonomous recording units as a key indication of environmental health. Because of the consequences of climate change and the rising number of endangered species, many experts suggested developing an animal species recognition system to help them in specialized research. Researchers can improve their ability to assess the state of biodiversity and its patterns in crucial ecosystems by precise sound detection and categorization, which is supported by machine learning, allowing them to better support global conservation efforts. However, producing analysis outputs with high precision and recall remains a difficulty. Due to a lack of appropriate methods for efficient and accurate extraction of interest signals, the vast bulk of data remains unexplored (e.g., bird calls). Moreover, due to strong source-domain specific features and artificial/natural noises, these acquired raw data create different distributions in datasets. So, to ensure a generalized feature learning, domain adaptation [1] techniques will be implemented in this work to make the networks familiar towards both acquisition sensor noises and background noises without having to do intensive dataset specific augmentations. We used 3 popular and powerful DNN models, including CNN, VGG19 and ResNet50. Out of them, for the bird species classification task VGG19 achieved the best accuracy of 96.02% in testing and 94.01% in training. To the best of our knowledge, this will guide towards convenient and deployable in real life models which will allow future works into the pipeline to ensure better coverage.

    A Fine Tune Robust Transfer Learning Based Approach for Brain Tumor Detection Using Vgg-16
    (Institute of Electrical and Electronics Engineers Inc., 2023-12-15) Islam, Rakibul; Akhi, Amatul Bushra; Akter, Farzana
    Brain tumor recognition by magnetic resonance imaging (MRI) is crucial because it improves survival rates and allows them to plan treatments accordingly. An accumulation of abnormal cells known as a brain tumor can spread to nearby tissues and endanger the patient. Magnetic resonance imagery is the primary imaging technique which determines the extent of brain tumors. Deep learning techniques rapidly grew in computer vision due to ample data for model training and improved designs on applications. MRI has shown promising results when using deep learning approaches to identify and classify brain tumors. This study uses MRI data and a convolutional neural network (CNN) to create a reliable transfer learning model that classifies tumors under four classes. Brain tumors' unwanted parts are excised, the quality is improved, and the cancer is coloured. By eliminating artefacts, decreasing noise, and boosting the image. The number of MRI images has increased using two augmentation techniques. A number of CNN architectures, including VGG19, VGG16, MobileNet, InceptionV3, and MobileNetV2 analyzed the augmented dataset. Where VGG-16 provides the accuracy of highest level. The best model underwent a hyperparameter ablation investigation, which led to the suggested hyper-tuned VGG16 obtaining 99.21% test and validation accuracy and 99.01% test accuracy.

    A Fine Tune VGG16 Model Based on Ablation Study for Diagnosing Brain Tumor from MRI Images
    (Daffodil International University, 23-01-29) Islam, Rakibul
    Brain tumor recognition by magnetic resonance imaging (MRI) is crucial because it improves survival rates and allows them to plan treatments accordingly. The patient is at risk if a tumour in the brain, which is made up of a cluster of abnormal cells, spreads to nearby tissues. MRI is the primary technique of imaging which is used for determining the extent of brain tumours. Deep Learning techniques have rapidly expanded in popularity in computer vision applications due to the abundance of data available for training models and advancements in designing models that provide more accurate estimations. When using deep learning techniques to recognize and categorize brain tumors, magnetic resonance imaging (MRI) has produced satisfactory performance. In this paper, we develop a strong deep-learning model which classifies brain tumors into four groups depending on MRI scans using a CNN. Unsolicited areas of brain tumours are deleted with the help of artefact removal, lowering noise, and quality-enhanced images. With improved image quality the cancer is tinted. The number of MRI images has increased using two augmentation techniques. The augmented dataset was analyzed by a number of CNN architectures, including VGG19, MobileNetV2, InceptionV3, VGG16, and Mobile Net. In this situation, VGG-16 offers the highest level of accuracy. The best model was then chosen, and a ablation study was performed on it based on the hyperparameters. The best outcomes were achieved by the hyper-tuned VGG16, which had test accuracy of 98.56% and validation and test accuracy of 99.23%.

    Assessing Early Stage Design of a mHealth App for Gestational Diabetes Mellitus Management in Bangladeshi Women
    (The International Diabetes Federation (IDF), 2023, 2023-10) Islam, Ashraful; AHMED, ESHTIAK; Zaman, Marzia; Rangon, Fairy Hasan; Amin, M Ashraful; Islam, Rakibul
    There is significant concern over the rising incidence of Gestational Diabetes Mellitus (GDM) among expectant mothers in Bangladesh [1]. Limited healthcare facilities in rural areas hinder prompt diagnosis and efficient management of GDM in Bangladesh. Despite mHealth's benefits, there is a lack of GDM management apps in Bangla, the native language of Bangladeshi citizens. To assess the viability of the first GDM management mHealth app in Bangla, users were asked about its early designs and functionalities. The app features a blood glucose tracker, food diary, medication reminder, educational resources, activity tracker, and personalized recommendations. 30 women with pre-existing GDM who were visiting a clinic in Dhaka, Bangladesh, were freely recruited during July 2023, and participation was anonymized. Participants ranged in age from 24 to 43 years (mean 33.43, SD 5.4). Following a briefing on the app's features and functionalities, participants were shown early sketches of the app. Later, they were prompted with a series of questions to provide feedback on the initial design and features. The majority (n=24) participants exhibited a positive response towards the app, expressing a wish that they had such a tool during their experience with GDM. However, 2 participants viewed the app as an impractical tool, while 3 were uncertain, expressing concerns about the accuracy of the information and guidance provided by the app. Beyond a textual interface, 1 participant suggested the inclusion of voice-based interaction to accommodate users who are illiterate, unfamiliar with using apps or having visual impairments. All participants appreciated the interface's use of the Bangla language and its cultural tailoring. 9 participants specifically highlighted the culturally tailored dietary recommendation feature as particularly praiseworthy. The app can play a crucial role in managing GDM in Bangladesh based on the early-stage evaluation feedback. However, further research is warranted to evaluate the real-world effectiveness and feasibility of it with a high-fidelity prototype for in-situ evaluation with the target users.

    (Malaysian Online Journal of Education, 2019) Hossain, Mohammad Emdad; Hoq, Mohammad Nazmul; Sultana, Israth; Islam, Rakibul; Hassan, Md. Zahid
    The purpose of this study is to identify the relative importance of factors that influence the students’ satisfaction at private and public universities in Bangladesh. Moreover, the study examines different demographic and socio-economic variables that also affect stakeholders’ satisfaction at university. Quantitative method research design was conducted for the study and a sample of 182 students was taken from different private and public universities in Bangladesh. The results showed that students were mostly satisfied with teachers’ expertise and design of course curriculum in both categories of universities in Bangladesh while food facilities had the lowest positive response factor of the students. The exceptionality of this study is to use binary logistic regression analysis to identify the most important demographic determinants regarding satisfaction. It is found that female students were less likely to be satisfied overall on their respective institutions than their male counterparts. In addition, students from the urban area and also from middle-class economic condition had more likely to be satisfied than any other counterparts. Understanding these variables could assist educational institutions with bettering their strategies to achieve their desired goal. Moreover, the strategy of development of strong personal relations with students and faculty members can definitely alleviate the dissatisfaction of the students.

    Determination of Strong Ion Difference and Anion Gap from blood biochemical parameters in Lactating Cow
    (Chattogram Veterinary and Animal Sciences University Khulshi, Chattagram-4225, Bangladesh, 2021-11) Islam, Rakibul
    The objectives of this study are to determine serum strong ion differences (SID) and anion gap (AG) of 8 high yielding lactating dairy cows with a history of inappetence and drop of milk production. Blood biochemical data of 8 cows were collected from diagnostic reports done at the Department of Physiology, Biochemistry and Pharmacology, Chattogram Veterinary and Animal Sciences University. Concentrations of quantitatively important strong ions (Na+, K+, Ca2+, Mg2+, Cl-) and nonvolatile buffer ions (total protein and phosphate) were determined and a fixed L-lactate value was used. Mean (±SD) of Strong ion difference (SID) was determined by calculating the differences between measured strong anion and cation concentrations (SID3, 37.56 mEq/L; SID4, 37.02 mEq/L; SID6, 40.14 mEq/L). Mean value of Atot, total plasma concentration of nonvolatile weak acids was calculated (Atot, 28.10 mmol/L) and this value along with a fixed value of Ka, effective dissociation constant for plasma weak acids and pH is then used to calculate concentrations of HCO3-. Anion Gap is then determined and the mean value of anion gap (AG) is 16.62 mEq/L, which is within the normal reference range. Although acid-base abnormalities are frequently present in sick animals. Measuring SID and AG will not only help in explaining the underlaying disease mechanisms of Acid-base disorders but also will help in proper treatment protocols.

    Effect of E-Banking on the Performance of Commercial Banks: A Case Study on Selected Banks of Bangladesh.
    (HAJEE MOHAMMAD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR., 2016-06) Islam, Rakibul; Saiful Islam
    In this present world, we are always interacting with Information & Technologies and always trying to keep pace with using new & newer Information & Technologies (IT) and IT related devices. E-Banking is one of the parts to become a digital Bangladesh and also it is being tried to adapt this in various organizations. As apparently, it can be assumed that the adaptation of E-Banking can produce good results for the organizations. This paper is a result of survey on the impact of E-Banking on the performance of commercial banks, particularly some banks in Dinajpur area. Continuous technological development, particularly information technology revolution of the decades has forced the banks to introduce the E-Banking operations for their sustainable growth in expanded competitive environment. E-Banking has made financial transactions easier for the participants and has introduced wide range of financial products and services. The main focus of this research is to present the scenario, prospects & the impact of E-Banking on the performance of commercial banks. The study is descriptive in nature and data were gathered both through direct observation and reaching at the websites of different banks, conversation with bankers and interview by structured questionnaires through random sampling technique with current customers of different banks. To measure operating performance, I have analyzed questionnaire data from respondents those are primary in nature. It indicates that operating performance of the banks is much more satisfied due to E-Banking systems. Again, ROE, ROCE and ROA are also calculated to measure financial performance with specified formulas data from annual reports. The result of this measurement shows that E-Banking has a negative effect on the performance of the commercial banks. Primary data analysis has produced commendable effect on the performance of banks. But secondary data analyses have provided the result that is after adaptation of E-Banking, Banking performance has been declined. And for this, only EBanking system is not liable. As we are in primary stage of adaptation process and our people are not well accustomed with the system that occur increase in operating expenses or more investment that didn’t provide required return. Again political instability and also the effect of economic slowdown may cause for this result. If everything remains better, we hope this system may provide a good result in near future. The study also highlights some constraints and steps of overcoming those constraints of E-Banking in banking sector of Bangladesh.

    Evaluating the Performance of Piled Raft Foundations on Soft Soil Using PLAXIS 2D
    (Daffodil International University, 2024-12-08) Islam, Rakibul
    A large number of building projects have been built on soft soil in recent years. Differential settlements can occur in structures built on soft soil because of its properties. The raft foundation is one way to lessen differential settling. It may result in excessive settling even when it has a sufficient bearing capacity. A piled raft foundation system is one that uses piles in conjunction with a raft foundation. The analysis of piled raft foundations in soft soil conditions presents a critical challenge in geotechnical engineering due to the complexities associated with soil-structure interactions and settlement behavior. This study employs PLAXIS 2D, a finite element analysis software, to investigate the performance of piled raft foundations subjected to varying load conditions on soft soil. The research aims to optimize the design by examining the contribution of piles to load sharing and settlement reduction. Key parameters such aspile length, pile spacing, and raft thickness are analyzed to evaluate their impact on the overall foundation behavior. Results from numerical simulations highlight the significant influence of pile arrangement and soil properties on the settlement response and load distribution efficiency. The findings provide a comprehensive understanding of the piled raft system, offering insights for the effective design of foundations in challenging soft soil environments, enhancing stability and reducing excessive settlement. Based on the permitted settlements, the ideal amount of piles for a piled raft foundation system must be taken into account for an economical design.

    Identification of molecular biomarkers and pathways of NSCLC
    (Journal of Genetic Engineering and Biotechnology, Springer, 2021-03-19) Islam, Rakibul; Ahmed, Liton; Paul, Bikash Kumar; Ahmed, Kawsar; Bhuiyan, Touhid; Ali Moni, Mohammad
    Background Worldwide, more than 80% of identified lung cancer cases are associated to the non-small cell lung cancer (NSCLC). We used microarray gene expression dataset GSE10245 to identify key biomarkers and associated pathways in NSCLC. Results To collect Differentially Expressed Genes (DEGs) from the dataset GSE10245, we applied the R statistical language. Functional analysis was completed using the Database for Annotation Visualization and Integrated Discovery (DAVID) online repository. The Differential Net database was used to construct Protein–protein interaction (PPI) network and visualized it with the Cytoscape software. Using the Molecular Complex Detection (MCODE) method, we identify clusters from the constructed PPI network. Finally, survival analysis was performed to acquire the overall survival (OS) values of the key genes. One thousand eighty two DEGs were unveiled after applying statistical criterion. Functional analysis showed that overexpressed DEGs were greatly involved with epidermis development and keratinocyte differentiation; the under-expressed DEGs were principally associated with the positive regulation of nitric oxide biosynthetic process and signal transduction. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway investigation explored that the overexpressed DEGs were highly involved with the cell cycle; the under-expressed DEGs were involved with cell adhesion molecules. The PPI network was constructed with 474 nodes and 2233 connections. Conclusions Using the connectivity method, 12 genes were considered as hub genes. Survival analysis showed worse OS value for SFN, DSP, and PHGDH. Outcomes indicate that Stratifin may play a crucial role in the development of NSCLC

    Mutual fund performance: an analysis of mutual funds’ return compare to the market return (DSEX).
    (BRAC University, 1/14/2015) Islam, Rakibul; Afiruzzaman, S. M.
    Mutual Fund is a Capital Market Investment Vehicle. In Bangladesh there are 48 Mutual Funds under 17 Asset Management Companies. This paper focused on evaluating the performance of 48 growth oriented mutual funds on the basis of weekly returns compared to market returns. Risk adjusted performance measures suggested by Jenson, Treynor, Sharpe and statistical models are employed. It is found that, most of the mutual funds have performed better according to Jenson and Treynor measures but not up to the benchmark on the basis of Sharpe ratio. However, most of the mutual funds are diversified and have reduced its unique risk. The growth oriented funds have performed better in terms of total risk and the funds are offering advantages of diversification and professionalism to the investors. So, mutual funds perform better with their expertise.
