ABSTRACT Every semester, students from each school in AUN take on their Senior Project. This project is expected to be a culmination of their work at the University and represent what they have learned. One of the biggest issues students have is what project they should take on. From the inception of AUN, there have undoubtedly been a great number of projects that have been done. Some could have been expanded upon or even improved; there has however seldom been an opportunity for this to tak...
ABSTRACT Condition monitoring of Electrical power equipment has attracted considerable attention for years. The aim of this work is to use Fuzzy logic (FL) Tool Box in building a simulation system that will diagnose all kinds of incipient faults, phase to phase fault and overloading in a transformer and monitor its conditions. Current and rate of change of current with time have been identified as the input variables, duly represented in the programme as “Error” and “Error-Dot”. Thes...
ABSTRACT The construction industry in developing countries is under tremendous pressure to improve its performance and the quality of its products and services. The small-scale construction firms dominate the construction industry and governments had globally recognized micro and small-scale enterprises as an instrument of economic growth and development. Past studies by various researchers have recommended a number of performance improvement strategies. However each country has peculiar prob...
ABSTRACT The study was undertaken to measure the variational change in residual chlorine decay in water distribution network. A total of 330 water sample were collected at different periods of the day for ten days. Ten water sample locations at water stand taps, were taken for the study area in Calabar South Local Government Area of Cross River State, Nigeria. The effect of various Pipe diameter, water sample point distance, change in chlorine concentration with time on residual chlorine and...
Abstract In industries like oil and gas, Telecommunication Networks used multiple communication technologies to eliminate any possibilities of failures, when the network is operational, in case of catastrophic situation these networks have strict and tight requirements for robust. Accordingly availability of the transmission network is essential, even short interruptions especially during catastrophic risks may cause considerable economic losses and major environmental impacts. In reality th...
Abstract Sediments resulting from soil erosion are the major non-point source pollutant of surface waters in agricultural watersheds. Annualized Agricultural Non-Point Source Pollution Model (AnnAGNPS) is a computer-based watershed model that predicts non-point source pollutants and runoff loadings within agricultural watersheds. AnnAGNPS v5.2 was used in conjunction with Arcview 3.2 GIS to predict streamflow and sediment discharges from a 250.89 ha agricultural watershed, Upper Ebonyi River...
ABSTRACT This study brought to the fore, a critical evaluation of the potentials of natural gas in the economic development of Nigeria. Natural gas option was considered the best alternative energy resource to other resources for optimizing income earning, indigent capacity building and the socio-economic development of an over populated Nigeria. Data and statistical reports from the various oil companies ere collaborated with the central bank economic report to determine the income generati...
ABSTRACT Automated Fish Feeder is a system, which focuses on aiding small scale fish farmers to feed their farms efficiently. By using Arduino and Internet of Things, this is made possible. This provides fish farmers with time and adequate information as the system is set to feed at several time intervals and send information through the internet should the feed container be low or empty . In addition, the system has so many potentials. The system can be embed into other systems such as a wa...
ABSTRACT Maintaining power system security of large power system is one of the challenging tasks to have secure operation point. The security assessment is an essential task as it gives the knowledge about the system state in the event of a contingency. Contingency analysis technique is being widely used to predict the effect of outages like buses, transmission lines, generators and inter-bus transformers, these may cause transmission line over loading and bus voltage limits violations. A...
ABSTRACT This world in which we are in is characterized by a multitude of natural phenomena. It is a world of change, of movement and energy; of storms, earthquakes, cosmic rays and solar flares. The range and complexity of these changes is so great, that it would seem the height of foolishness to attempt to find a common trend, or a theme that runs through them all. Never the less, men have come to the understanding of the factors involved. At the heart of such a science is the concept of en...
Abstract: Sequence stratigraphy model developed for the Ningning field is based on the interpretation carried out on the different wells that penetrated the various subsurface lithologies. Basically three depositional sequences were delineated from the five wells studied. The Vail model used made out a third and forth order stratigraphic surfaces that all fall within the central swamp depobelt of the Basin. The five wells used show the presentation of the interpretation and the models. All th...
ABSTRACT. Cost effective steel utilization as distinct from steel utilization is an engineering challenge of our time, especially in this austere period. Steel scrap recovery is defmitely one of the areas to be seriously looked into by Nigerian engineers. After estimating the recoverable steel scrap to the year 200AD, this paper aims at fmding an appropriate technology and size for steel scrap recovery bearing in mind the need for self reliance and the level of our technological advancement....

Abstract This Study Examined The Effects Of Effluent Discharges From Various Point-Loads On A Purposively Selected Receiving River, The Self-Recovery Ability Of The River And The Treatability Of Both The Discharges And The Receiving Stream In A Heavily Industrialized Community. The Work Involved Field Survey Of Industries Producing And Discharging Effluents In The Study Area (Ado Odo/ Otta Industrial Zone Of Ogun State, Nigeria); Determination Of The Effluents‘ Physico – Chemical, Biolog...
ABSTRACT This paper deals with the measurement of dielectric properties of some local cereals (com, beans, rice) in the audio frequency range (0.3- 20KHz) since dielectric properties of various agrofoods and biological materials are finding increasing applications, as fast and new technologies adapt/adopt these cereals for use in their respective industries and research laboratories. A Marconi instrument, 0.1% universal impedance bridge together with a specially designed and constructed coax...
