Automated Diabetic Retinopathy Detection Using Bag of Words Approach  [PDF]
Monzurul Islam, Anh V. Dinh, Khan A. Wahid
Journal of Biomedical Science and Engineering (JBiSE) , 2017, DOI: 10.4236/jbise.2017.105B010
Imaging and computer vision systems offer the ability to study quantitatively on human physiology. On contrary, manual interpretation requires tremendous amount of work, expertise and excessive processing time. This work presents an algorithm that integrates image processing and machine learning to diagnose diabetic retinopathy from retinal fundus images. This automated method classifies diabetic retinopathy (or absence thereof) based on a dataset collected from some publicly available database such as DRIDB0, DRIDB1, MESSIDOR, STARE and HRF. Our approach utilizes bag of words model with Speeded Up Robust Features and demonstrate classification over 180 fundus images containing lesions (hard exudates, soft exudates, microaneurysms, and haemorrhages) and non-lesions with an accuracy of 94.4%, precision of 94%, recall and f1-score of 94% and AUC of 95%. Thus, the proposed approach presents a path toward precise and automated diabetic retinopathy diagnosis on a massive scale.

Abstract: New advances in enabling technologies, as well as the growth of Internet traffic have continuously driven the fast evolution of networks. All optical packet switching provides high throughput, rich routing functionalities and excellent flexibility. These characteristics make it an excellent candidate for next-generation metropolitan area networks, which will be much more dynamic and demanding than today s networks. This study proposes Dense Wavelength Division Multiplexing (DWDM) based data networking using fiber optical backbone in a Dhaka city of Bangladesh. DWDM is used in this study as a backbone controller from centralized location. Two DWDM devices are placed at the two important location of the Dhaka city. DWDM based optical infrastructure is a future demanded technology.
The Impact of Television on Sexual Attitudes and Behaviors among Teenagers, Ages 15 - 17 Years Old, in the City of Klina, Kosovo  [PDF]
Islam Borinca
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.66068
Abstract: Sexual content on television has been shown to have significant impacts on sexual attitudes and behaviours of people, especially among teenagers. Consequently, numerous studies have been conducted over the last decade to examine the connection among these areas, among other goals. Also, it is an attempt to analyze the connection between sexual attitudes and behaviours of teens and sexual content on television, as well as the dissatisfaction created, as a result of the high levels of these contents. 80 students were included in this study, conveniently selected from three schools in the city of Klina. The hypothesis is that portrayals of sex on television lead adolescents to sexual relationships. In addition, high levels of sexual content push teens to dissatisfaction with their sexual experiences. From the obtained results, it is concluded that, although TV provides consid-erable levels of sexual content, it does not encourage teenagers to early sexual intercourse, but if TV shows such content in high levels, then teenagers can be disappointed with their experience and have health as well as social problems.
Governance Matters and Economic Growth: Beyond the Egyptian Revolution  [PDF]
Islam Abdelbary
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.84051
Abstract: Following the Egyptian revolution in January 2011, the need for a new development approach has become essential. That is development with a human face. This study aims to contribute to the discussion on sustainable economic growth in Egypt by examining the interdependence of inclusive governance, economic and social inclusion, through empirically assessing the relationship between governance indicators and economic growth in Egypt. The study applied a vector error correction model (VECM) to assess the causal relationship between the two key variables, using Worldwide Governance Indicators (WGI) from the World Bank and economic indicators from Economic Intelligent Unit (EIU) database over the period 1996-2016. The results show that the Egyptian economy suffered during the study period from a significant decrease in the level of governance. The analysis indicated that most of the governance indicators have a causal relationship with economic growth except corruption control, while economic growth has a positive effect and contributes to the development of political stability and regulatory quality. The paper concludes that appropriate initiatives and efficient governance could play a significant role in influencing economic growth in Egypt. This is consistent with previous studies on the impact of institutions on economic growth and development. However, these results need further investigation to determine additional key variables that influence the growth of GDP in Egypt.

This is about 25℃ in afternoon hours.
Insights the Practice of Integrated Reporting: A Study on MNCs in Bangladesh on the Degree of Adherence to the Reporting Framework  [PDF]
Ranjita Islam, Mohammad Rakibul Islam
Open Journal of Business and Management (OJBM) , 2018, DOI: 10.4236/ojbm.2018.63056
Integrated Reporting (IR) stands for organizational reporting which is prepared for public disclosure and includes both financial and important non-financial information. Existing financial reporting standards are inadequate to address issues like the importance of intangible assets, corporate impacts on the environment, human health, societal conditions and corporate influence on the political process. Thus, the concept of IR emerged to deal with these issues that affect corporate success. The traditional reporting model focuses on a relatively narrow account of historical financial performance of the value-creation process. Keeping this in mind, the International Integrated Reporting Council (IIRC) has developed an International Integrated Reporting Framework, the core objective of which is to guide organizations in communicating the broad set of information needed by investors and other stakeholders to assess the organization’s long-term prospects in a clear, concise, connected and comparable format. The IIRC shares the view that the evolution of corporate reporting should be led by the communication of value creation by the corporate entities. This paper focuses on the degree of disclosure of Integrated Reporting requirements by the top eleven multinational companies of Bangladesh as per market capitalization. Using annual report content analysis, the findings show that the companies have lately started providing non-financial information regarding environment, society and governance along with financial figures. But it is prominent that they are still providing these information in disconnected strands and as a part of Corporate Governance or CSR disclosures instead of linking these to financial information and providing it as an integrated report.
A Modified and Secured RSA Public Key Cryptosystem Based on “n” Prime Numbers  [PDF]
Muhammad Ariful Islam, Md. Ashraful Islam, Nazrul Islam, Boishakhi Shabnam
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.63006
Abstract: Cryptography is the study that provides security service. It concerns with confidentiality, integrity, and authentication. Public key cryptography provides an enormous revolution in the field of the cryptosystem. It uses two different keys where keys are related in such a way that, the public key can use to encrypt the message and private key can be used to decrypt the message. This paper proposed an enhanced and modified approach of RSA cryptosystem based on “n” distinct prime number. This existence of “n” prime number increases the difficulty of the factoring of the variable “N” which increases the complexity of the algorithm. In this approach, two different public key and private key generated from the large factor of the variable “N” and perform a double encryption-decryption operation which affords more security. Experiment on a set of a random number provided that the key generation time, analysis of variable “N”, encryption and decryption will take a long time compared to traditional RSA. Thus, this approach is more efficient, highly secured and not easily breakable.
Detection of Mechanical Deformation in Old Aged Power Transformer Using Cross Correlation Co-Efficient Analysis Method  [PDF]
Asif Islam, Shahidul Islam Khan, Aminul Hoque
Energy and Power Engineering (EPE) , 2011, DOI: 10.4236/epe.2011.34073
Abstract: Detection of minor faults in power transformer active part is essential because minor faults may develop and lead to major faults and finally irretrievable damages occur. Sweep Frequency Response Analysis (SFRA) is an effective low-voltage, off-line diagnostic tool used for finding out any possible winding displacement or mechanical deterioration inside the Transformer, due to large electromechanical forces occurring from the fault currents or due to Transformer transportation and relocation. In this method, the frequency response of a transformer is taken both at manufacturing industry and concern site. Then both the response is compared to predict the fault taken place in active part. But in old aged transformers, the primary reference response is unavailable. So Cross Correlation Co-Efficient (CCF) measurement technique can be a vital process for fault detection in these transformers. In this paper, theoretical background of SFRA technique has been elaborated and through several case studies, the effectiveness of CCF parameter for fault detection has been represented.
Correlation between Atmospheric Temperature and Soil Temperature: A Case Study for Dhaka, Bangladesh  [PDF]
Khandaker Iftekharul Islam, Anisuzzaman Khan, Tanaz Islam
Atmospheric and Climate Sciences (ACS) , 2015, DOI: 10.4236/acs.2015.53014
Abstract: The main intention of this study was to substantiate the relation between atmospheric temperature and soil temperature within a system boundary. The study focused on coefficient of correlation that demonstrates the association between two variables. The earth surface temperature is anticipated to be affected by a set of meteorological parameters. Atmospheric temperature, humidity, precipitation and solar radiation directly influence the adjacent soil and the extent of impact must be varied at different part of the earth because of multiple factors. The primary step to validate the correlation was to collect two series of data for two variables i.e. atmospheric temperature and soil temperature of last ten years from 2003 to 2012. The coefficient of correlation was determined through Pearson’s distribution whereas atmospheric temperature was considered as independent and soil temperature was dependent variable. The coefficients were calculated distinctly taking the soil temperature not only at several depths but also at separate faces of a day commensurate to overlying air temperature. The results indicated strong positive correlation up to 20 cm depth of soil which blatantly validates the premise of the study. The procedure was concluded with the regression analyses through which dependent variable (soil temperature) is projected corresponding to independent variable (air temperature). All possible coefficients of correlation were gathered in order to make the final comparison and analyses over the variation of magnitudes. Anomalies at which two variables are unable to continue linearity were portrayed in figures of the paper. Finally, influence graph is made to illustrate relative influence at different nominated depth of soil based on the coefficient of correlation.
Land Rights, Land Disputes and Land Administration in Bangladesh—A Critical Study  [PDF]
Shahidul Islam, Golam Moula, Mominul Islam
Beijing Law Review (BLR) , 2015, DOI: 10.4236/blr.2015.63019
Abstract: The article examines the various ways to ensure land rights and also recommends different mechanism to settle land dispute. It is also intended to highlight the problems of present land administration of Bangladesh and to suggest the reformation of the land administration for proper management of land. Land turns around the life of the people of Bangladesh. The present land laws, land administration and land management in Bangladesh are not only full of intricacy, procedural difficulties and mismanagement but also not accessible and responsive to the interest of the common people of the country. Furthermore, the present mechanism to settle land dispute is not time saving, cost effective, peaceful and sophisticated. If the land laws are made public spirited and land administration is made well-structured in the sense of good governance, e-governance and development, land interest of the common people is upheld and land disputes are settled with public satisfaction and confidence, a revolutionary change may bring about in the socio-economic development of the common people.
