A novel approach Using acknowledgement for highly efficient secured intrusion -detection system for MANETS

A wireless network is method by which homes, telecommunications network and business enterprise installations, avoid the costly process of introducing the cables or connection between various equipment locations. Mobile ad hoc networks are an infrastructure less internet protocol based network. The absence of centralized firewall and distributed nature of operation of nodes make MANETS vulnerable to malicious attacks. In this case, it is crucial to develop efficient intrusion-detection mechanisms to protect MANET from attacks. With the improvements of the technology and cut in hardware costs, we are witnessing a current trend of expanding MANETs into industrial applications. To adjust to such trend, it is vital to address its potential security issues. In this paper, we propose and implement a new intrusion-detection system named Enhanced Adaptive Acknowledgment (EAACK) specially designed for MANETs. Compared to contemporary approaches, EAACK demonstrates higher malicious behavior detection rates in certain circumstances while does not greatly affect the network performances.
Reporting Standard ’ s ( IFRS ) Adoption in Ghana : Rationale , Benefits and Challenges 1

The International Financial Reporting Standards (IFRS) was adopted by Ghana in 2007. The study assessed eighteen (18) professional accountants from listed firms on the Ghana Stock Exchange (GSE), to measure the benefits and challenges of IFRS. The study revealed that IFRS improved the access of local companies to international markets. It was also observed that the local firms gained more credibility, transparency, acceptance and consolidation following its adoption. However, most respondents believed that decreasing information cost, competitive leading edge, and integration of accounting Information Technology system were not major benefits as proposed by literature. Nonetheless, some of these local companies after the migration faced challenges like coping with the sophistication of the new standard, lack of qualified personnel, and additional operational cost. Nevertheless, most of the respondents disagreed with the proposition that IFRS had a negative impact on their firms‘ balance of retained earnings.
A Context Aware Recommendation System through Exploring and Optimizing Latent Preferences

- Recommender system is a tool that provides personalized service to help users to find their desired content. Context-aware recommendations personalize the search for such desired content by considering the contextual information. In many recommendation aspects, incorporating the context of users has been shown to improve the quality of recommendations. In this work, we propose a model that improves the user experience of finding the content they desire by analyzing their contextual information. By conducting an empirical analysis of a dataset from last.fm, we demonstrate the extraction of latent preferences for recommending items under a given context and study how contextual information can be exploited to improve the prediction accuracy of recommender systems. Additionally, we use an optimization function to further minimize the root mean square error (RMSE) measure of the resulted prediction capability of the latent preference models. Finally, we proposed a latent collaborative preference model to predict the final rating of users to items by combining the extracted latent preference models. The experimental results achieved in this work shows our context-aware latent collaborative model can improve the prediction accuracy of recommender systems as compared to state of the art non-context aware approaches.

Isolation and identification of oil utilizing microorganisms from different environmental sources

Microorganisms such as bacteria, fungi, yeast etc. present in a wide range of environments have been capable of producing biosurfactants. Thus different biosurfactants are classified according to the presence of sugar, amine or lipid group and they are rhamnolipid, lipopeptide, polymeric biosurfactants etc. Their multiple uses as antimicrobial agent, bioremediation of environmental pollutants, pesticides etc. have increased its significance for its large production. Total 27 different environmental samples were collected from VIT University, Vellore and Ottappalam, Palakkad District of India. 27 isolates from soil, 12 from water and 11 from salt pan samples were isolated and biosurfactant activity of these isolates was measured by oil displacement. 54%, 30% and 16% of the isolates were categorized into low, moderate and high biosurfactant producing isolates, respectively. 14 isolates were further selected for 16S rRNA sequencing according to their activities. Using these results, phylogenetic tree analysis was performed with the strains submitted in NCBI which have been reported to have biosurfactant activity. From those 14 strains, six strain sequences were submitted in the GenBank and acquired accession numbers. Biochemical characterization was also used for the identification of strains. Since these isolated strains were found to be capable of producing biosurfactants, they can be potential candidates for environmental application.
A Survey on Honeyword Based Password Cracking Detection System

— The previous research in the area of security tells that many password hashes are vulnerable to hackers. Honeywords(fake passwords) are suitable to detect attacks against hashed password databases. Honeyword approach stores the number of password for each user account in order to detect the existence of an attacker. Proper honeywords selection accidents an adversary for stealing a file of hashed passwords, because an adversary can not sure whether the password is real or a fake for any account. The HoneyChecker (a secure server) is used to distinguish between a user’s real password between the honeywords of each user. However, an attacker made attempt login with different kind of combinations generated from hashed password database if it is a honeyword, additionally the system will take appropriate actions against attacker, that specific actions set by an administrator. In this survey paper, study, we study the honeyword generation methodology and different attacking scenarios as well as different related approach to the honeywords

IMPACT ASSESSMENT OF MICROCREDIT ON THE WELL-BEING OF WOMEN IN GHANA A CASE OF ATWIMA MPONUA DISTRICT, GHANA

The World Bank and other development agencies recognize the importance of women‘s access to financial resources as an important strategy in poverty reduction. Donors, therefore, continue to direct microfinance services and resources to women as a way of encouraging productivity. In spite of the proliferation of Microfinance Institutions and services (MFIs) in Ghana, poverty is still ubiquitous especially in the rural areas among women. Using a sample of 400 women in the informal sector from Atwima Mponua District of Ghana, and Ordered logistic regression analysis, this study was basically conducted to find the impact of MFI microcredit’s or loans received by women on their well-being using four well-being indicators in Ghana. The major finding was that women utilised the services of microfinance institutions, but few have access to credit or loans. The women who accessed credits had improved well-being in relation to their ability to afford quality healthcare, children’s education and comfortability in current accommodation than non-beneficiaries. This study therefore recommended that policies must be adopted to encourage the MFIs to grant more loans to more women.
