A Reformed Information Security Management System (R-ISMS)

An Information Security Management System (ISMS) specifies the instruments and methods that an administration/management level of an institution uses to comprehensibly manage the tasks and activities aimed at achieving information security. ISMS evolved as a systematic and structured approach to managing information following advances in IT infrastructure, services and applications so that they remain secure. While there are various implemented ISMS frameworks, researchers continually try to emphasize and increase human participation in ensuring information security. The aim of this research study is to develop an algorithm-based model to facilitate effective ISMS services for organizations. This algorithm-based ISMS model employed Information Technology General Controls (ITGC) technique as an expansion of the vistas of known ISMS frameworks, to improve information security control in organizations. The purpose of refinement is to make the frameworks more easily understood, implemented, and measured in organizations by stakeholders.Microsoft Office Visio 2010 software was used in designing the reformed model. Bactracking and Branch-and-bound algorithms were used in developing the model. The model utilises the above named methods to address the problem of inadequate management systems for information security. The results of this study showed that, with the level of usability, International Organization for Standardization (ISO) standards are more easily implemented and well recognized by stakeholders (top management, staff, suppliers, customers/clients, regulators) unlike the other security frameworks.  In conclusion, this study showed that R-ISMS is a customized algorithm model that assists organizations to enhance the ability in monitoring the performance of their activities, policies and procedures.

Proposed Multi-Mode Home Node-B Air Interface Protocol Stack Architecture

A Multi-mode Home NodeB (MHNB) is a system that can offer cellular service(s) to more than one different generation technology. The Universal Mobile Telecommunication System (UMTS) technology using NodeB as its transceiver station was developed to offer a high frequency range of 5MHz and because of this, the signal from the NodeB dilutes faster once reaching indoor. Studies showed that the idea of Home NodeB system by Third Generation Partnership Project (3GPP) came as a means to boost the diluted indoor signals. The challenge with this system is that it can only accommodate small number of subscribers as its Close Subscriber Group (CSG) without allowance for expansion. This study seeks to address the small capacity issue of the existing HNB by proposing a system that will accommodate wider capacity range and also, modify its operation from a single network mode to a Multi network mode technology. This will also offer great benefit to developing countries through extension of their GSM coverage and will also create a uniform platform for all cellular generation technologies.

Femtocell Congestion Mitigation Technique using Poisson Point Process

The idea of femtocell technology came in order to boost the signal strength of indoor Universal Mobile Telecommunication System (UMTS) users. The number of subscribers a femtocell device can accommodate is closed from the manufactures’ end in order to check the capacity limit. The challenge with this form of technology is that only registered subscribers are permitted to gain access. This study seeks to enable flexibility in the control of its capacity limit by employing Poisson Point Process as a congestion control tool. The outcome of the study showed that the spatial Poisson Point Process can effectively be used to control the capacity limit of femtocell device, using co-channel interference technique. This will enable the device to operate as an open system while controlling the capacity limit. Keywords: Femtocell, Poisson Point Process, Cellular Network, Home Node

Antioxidant and antimicrobial evaluation of the methanol leaf extract and fractions of dacryodes klaineana pierre (burseraceae)

ABSTRACT. Dacryodes klaineana is used in traditional medicine for the treatment of painful menstruation; tachycardia and cough. The study aims to evaluate the antioxidant and antimicrobial properties of the plant. The extract and fractions of D. klaineana were screened for their antioxidant effects using the 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and the total phenolic contents (TPC) assay methods. The antimicrobial activity of the plant was evaluated using the agar diffusion method against four different bacterialstrains (Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa) and two fungi strains (Aspergillus niger and Candida albicans). The crude methanol extract (MLE), hexane fraction (MLHF), ethyl acetate fraction (MLEF) and butanol fraction (MLBF) produced dose-dependent antioxidant activity using DPPH and FRAP assays. The antioxidant activity of MLEF was comparable to the standard drug, ascorbic acid. MLEF also gave the highest content of total phenol content with a percent gallic acid equivalent of 100.68 ± 1.17 mg GAE/g. The extract and fractions were active against the bacteria species, but inactive against the fungi species. The study demonstrated that the antioxidant and antimicrobial potentials of D. klaineana may offer a promising source of new antioxidants and antimicrobials in the ethnomedicinal management of diseases.                 KEY WORDS: Medicinal plant, FRAP, TPC, DPPH, Antioxidant, Dacryodes klaineana   Bull.
