  • Development of Winter Season Optimal Tilt Angle Model for Fixed Tilted Plane PV Installation in Akwa Ibom State, Nigeria

    Ekpenyong, Akpan Ikoedem; Umoren, Anthony Mfonobong; Markson, Idorenyin (2017)
    In this paper, a polynomial model is developed for determining the winter season optimal tilt angle for fixed-tilt PV installations in Uyo metropolis, Akwa state of Nigeria. Satellite-derived NASA SSE  solar radiation data  was used in the  study and the simulation was done using PVSyst software. The polynomial  model is given as  WTF(β)= -0.00013(β^2 ) + 0.00643(β) + 0.99991; where WTF(β)  is the winter average transposition factor and β is the tilt angle in degrees. The model has prediction...

    Flowchart for Clustered-Based Channel Allocation Management Scheme

    Ezenugu, Isaac A.; Eke, James; Onoh, G. N. (2017)
    In the GSM system, several Base Transceiver Station (BTS) are controlled by a single Base Station Controller (BSC). In this paper, the BTSs in a given BSC is referred to as a cluster.  In this paper, flowchart for clustered-based channel allocation management scheme is presented. The mechanism is meant to reduce call blocking/dropping to the barest minimum. Usually, traffic intensity value varies from one BTS to another, as it is directly proportional to the number of GSM users that make or r...

    Development of Students Result Management System: A case study of University of Uyo

    Ekanem, Akpasam Joseph; Ozuomba, Simeon; Jimoh, Afolayan J. (2017)
    In this paper, an automated platform for managing result of all categories of students in a seamless and interactive manner is presented. The system was developed using PHP, CSS, HTML, MYSQL and was hosted locally using Apache web server. The software development methodology adopted is a participatory incremental process model (PIP Model). The data used were obtained from the Department of Electrical/Electronic and Computer Engineering, University of Uyo. Functional decomposition of the syste...

    Scanning for Vulnerabilities in the Security Mechanisms of the Hosts in the Academic Institutions and Government Agencies

    Hristov, Hristo (2018)
    In this paper a sophisticated investigation and scanning for vulnerabilities in the security mechanisms of the hosts in the academic institutions and government agencies is made. The port and network scanner are specialized software tools that can discover detail information about the selected target hosts such as open, filtered, closed ports and the whole computer network topology.

    Modelling of Nigerian Residential Electricity Consumption Using Multiple Regression Model with One Period Lagged Dependent Variable

    Amlabu, Runcie; Okpura, Nseobong I.; Umoren, Anthony Mfonobong (2017)
    This paper presents the modelling and forecasting of residential electricity consumption in Nigeria based on nine years (2006 and 2014) data and  multiple regression model with one period lagged dependent variable. A Socio economic parameter (population), and climatic parameter (annual average temperature) are used as explanatory variables in modelling the and  forecasting of residential electricity consumption in Nigeria. The results of the multiple regression analysis applied to the data ar...
