    CAMDIT: A Toolkit for Integrating Heteregeneous Data for Enhanced Service Provisioning
    (IEEE International, 2014-11-03) Ipadeola, A; Ipadeola, O; Ameen, Ahmed O; Sadiku, Joseph S
    Data Integration is classified as an Open and Lingering (OL) problem which must be sufficiently addressed due to its myriad benefits and significances, especially in the health sector where collaborative medicine is vital. Data integration problem evolved from the disparity in semantics and syntactic representations of medical data. It is a challenge, which must be solved to realize effective collaboration in the health sector and paramount for efficient health care service provisioning. In recent times, different approaches and software artifacts such as services, components and tools have been proposed for resolving data integration problem. However, existing approaches are faced with data inaccuracy, data unreliability, increased query response time, network bottleneck and poor system performance. The focus of this paper is to present our technique and the CAMDIT toolkit which efficiently achieves data integration, data accuracy, reliability and reduced query-response time and impacts of network bottleneck on systems performances.Data Integration is classified as an Open and Lingering (OL) problem which must be sufficiently addressed due to its myriad benefits and significances, especially in the health sector where collaborative medicine is vital.

    DESIGN AND ANALYSIS OF NETWORK MODELS FOR QOS ROUTERS ON UDP AND CBR
    (Georgian Technical University & St Andrew University of Patriarchy of Georgia, 2017) Ameen, Ahmed O; Olatinwo, D D; Alamu, F O; Olatinwo, S O; Balogun, A O
    To address the issues of packet delay and unfairness among multimedia UDP flows, this paper presents the design and evaluation of network models to study different parameters for quality-of-service (QoS) provisioning in differentiated service (DiffServ) routers using user datagram protocol (UDP) as network traffic agent and constant bit rate (CBR) as traffic generator. Traffic marker algorithms are used to define the treatment an incoming traffic (packet streams) receives at the edge routers in a DiffServ domain. In order to implement the TSW2CM and TSW3CM marker algorithms, a network model was designed. The designed models were simulated, analysed and evaluated. For the purpose of evaluation, packet delay and fairness index were considered. The obtained evaluation results were analysed based on a ranking system approach to showcase the strengths and weaknesses of the TSW2CM and TSW3CM algorithms for multimedia UDP flows. The adopted approach showed that the TSW3CM algorithm was ranked first with a packet delay value of 0.237704 while TSW2CM algorithm was marked second (with 0.431778), and the TSW3CM algorithm was ranked first with a fairness rate value of 0.3823960 while TSW2CM algorithm was ranked second (with 0.2817353). The obtained results indicate that applications that requires low packet delay can be deployed on UDP protocol using TSW3CM algorithm while applications that requires high fairness rate values can be deployed on UDP protocol using TSW3CM algorithm.

    Design and Development of a Safe and Effective Online Marketplace for Nigeria
    (Faculty of Management and Social Science, Geofrey Okoy University, Enugu, Nigeria, 2017-12-01) Ameen, Ahmed O; Aremu, Mukaila A; Olagunju, Mukaila; Awotunde, Joseph B; Olowe, O T
    Buying and selling has gone beyond what is carried out only in a physical environment, as the availability of internet has made market and marketing a thing done online. Most online marketplaces (Websites) are individually managed in a way that it monopolises and restricts users to only products and services placed on them, thereby making users to think that only goods placed on such media are those available in the market. The paper proposed, designed and developed a web-based marketplace system using UML (Unified Model Language) and PHP as the Front-end (Programming Language) and MYSQL as the back-end (Database) running under WAMP (Window, Apache, PHP and MYSQL) Platform. The study used Case diagram and Class diagram, offered by UML for designing the system. The system provides a secured marketplace for products and services with the resources available online which is secure and provide customers marketplace with unlimited and unrestricted search. With the adoption of limited search engine optimisation that converges, accesses to various marketplaces through the use of links have been made possible. The study recommended that online marketplace should be improved on by not only limited to products in the country but goods and services outside the country

    Design and Development of a Unified Subscrbers' Sim Registration Platform Using Top-Down Approach
    (Department of Library and Information Technology, Federal University of Technology, Minna, Nigeria, 2016-12-02) Ameen, Ahmed O; Akanni, O A; Alimi, O M; Haliru, S
    Compulsory SIM registration in Nigeria started in 2008 in response to several mobile crimes being perpetrated by fraudsters and also to improve service delivery. The decentralized systems currently in use in the country lack flexibility to register heterogeneous SIM cards and encourage multiple registrations. This work, the “design and development of a centralized, unified subscribers‟ SIM registration platform” therefore seeks to address these loopholes. The work employs top-down design approach using HTML, PHP, JAVASCRIPT, CSS, and MySQL as development tools. The new system surpasses the existing one as it is able to register all SIM cards of the four (4) major telecommunication operators in Nigeria and verify if a SIM had already been registered thus bringing stability, flexibility, and single platform for all. It is recommended that SIM card availability/sales on the road side should be stopped or such SIM cards be denied access to network until they are properly registered.

    Development of E-wallet System for Tertiary Institution in a Developing Country
    (Georgian Technical University & St Andrew University of Patriarchy of Georgia, 2016) Fashoto, Stephen G; Uzoka, F M E; Ameen, Ahmed O; Mabayoje, M
    The absence of adequate automated teller machines (ATMs) and banks in and around some university campuses has left students high and dry on many occasions. After banking hours, in a situation where ATMs are unable to dispense cash, students are left unable to purchase products they need at that time. The research methodology develops a new prototype for a practical e-wallet whose goal is to allow the instant money transfers between two users. Although the e-Wallet concept has many implementations, we improve the present level of knowledge by joining the online technology and the classic concepts about money restricted to the university students portal/server due to lack of bank network most times on campus. As opposed to the storing of various plastic card details on the mobile device, a single virtual card is suggested. Monetary value can be transferred to the virtual card. The proposed e-wallet system is very essential as it ensure access to funds kept in the virtual account at alltime via the internet; these reduce the dependency on the ATMs. The e-wallet system is a vital tool in the tertiary institutions. It is of benefit to students and merchants within the campus and thus should be properly managed

    Performance Analysis of Network Trafficfor Diffserv QoS Router
    (Pacific Juornal of Science and Technology, Akamai University, 2017) Ameen, Ahmed O; Olatinwo, D D; Olatinwo, S O
    This paper presents the design and evaluation of network traffic models to examine the strengths and weaknesses of the TSW2CM and TSW3CM algorithms on different data traffic using transmission control protocol (TCP) and file transfer protocol as the traffic protocol (agent) and traffic generator. The TSW2CM and TSW3CM algorithms were implemented on the designed traffic models to define the treatment each traffic scenario receives as it transverses through the routers in the network. The traffic models were simulated, analyzed, and evaluated. The evaluation was done using packet loss and one-way latency (packet delay) as QoS parameters, and the simulation was carried out on network simulator 2 (NS-2). The results obtained in this study were further analyzed using a ranking system approach which revealed the strengths and weaknesses of various applications (TCP traffic flow) on TSW2CM and TSW3CM algorithms using the above mentioned QoS parameters. The ranking system revealed that TCP-traffic based on TSW2CM and TSW3CM algorithms had a packet loss rate of 0.23% and 0.90%, and one-way packet delay values of 0.058282 and 0.045672, respectively. Therefore, the evaluation results revealed that applications that require a low packet loss rate can be deployed on TCP protocol using TSW2CM algorithm, and applications that requires a low latency (packet delay) can be deployed on TCP protocol using TSW3CM algorithm.

    The reported preparedness and disposition by students in a Nigerian university towards the use of information technology for medical education
    (Usman Danfodiyo University Sokoto, 2010) Fadeyi, A; Desalu, O O; Ameen, Ahmed O
    Background: The computer and information technology (IT) revolution have transformed modern health care systems in the areas of communication, storage, retrieval of medical information and teaching, but little is known about IT skill and use in most developing nations. Objectives: The aim of this study has been to evaluate the reported preparedness and disposition by medical students in a Nigerian university toward the use of IT for medical education. Methods: A self-administered structured questionnaire containing 24 items was used to obtain information from medical students in the University of Ilorin, Nigeria on their level of computer usage, knowledge of computer software and hardware, availability and access to computer, possession of personal computer and e-mail address, preferred method of medical education and the use of computer as a supplement to medical education. Results: Out of 479 medical students, 179 (37.4%) had basic computer skills, 209 (43.6%) had intermediate skills and 58(12.1%) had advanced computer skills. Three hundred and thirty (68.9%) have access to computer and 451(94.2%) have e-mail addresses. For medical teaching, majority (83.09%), preferred live lecture, 56.78% lecture videos, 35.1% lecture handout on web site and 410 (85.6%) wants computer as a supplement to live lectures. Less than half (39.5%) wants laptop acquisition to be mandatory. Students with advanced computer skills were well prepared and disposed to IT than those with basic computer skill. Conclusion: The findings revealed that the medical students with advanced computer skills were well prepared and disposed to IT based medical education. Therefore, high level of computer skill is required for them to be prepared and favorably disposed to IT based medical education.
