ABSTRACT This work examined thermo-mechanical and metallurgical parameters (temperature and cooling rate) that give rise to substantial improvement in the basic functional strength characteristics of high-yield reinforcing steels produced in a conventional mill. A new process tagged Temperature Tracking-Jet Water Spray (TT-JEWAS) was developed to achieve requisite in-process control of thermal variations on one hand and fast undercooling by spray quenching on the other. The alternative micro...
SUMMARY Metal forming is a production technique which enhances economic use of engineering material by minimizing metal wastage that occurs in machining processes such as lathe turning and milling. This technique employs a press tool for mass production of parts that are dimensionally compatible. The press tool comprises the section that provides the force the press, and the tooling section the die. Investigation of stretch-forming conditions to produce a si dome in order to determine the opt...
ABSTRACT The quest for effective forecasting models to meet the ever growing electricity demand around the globe has heightened and taken a much challenging dimension that cuts across rural and urban communities in under-developed, developing and developed economies. Electric Load Forecasting which is the accurate prediction of both the magnitude and geographical distributions of electrical energy demand over the different periods of planning horizon has become a vital process in the planning...
ABSTRACT On the 27th June, 1995, the Engineering professionals, policy makers , representatives from various sectors and the Hon. Minister of Works and Housing - Major General Abdukarim Adisa gathered here to witness the launching of the NIGERIAN ASSOCIATION OF ENGINEERING CRAFTSMEN (NAEC). An Association that into existence in 1993 after the amended Decree 55/70 by 27/92 which empowered COREN to regulate engineering profession in Nigeria.
ABSTRACTA study was undertaken to developed a model that will be used to predict sugar and theby-products from sugar cane. The model developed from MATLAB was used to predictthe sugar, bagasse, filter cake and molasses yield from sugar cane. The predicted valuesfrom the model were compared to yield data obtained from the production of sugar canefrom the Savannah Sugar Company, Numan, Nigeria for 90 days. The analysis ofvariance (ANOVA) at p ≤ 0.01 was used to determine if there were signifi...
ABSTRACT Locating the position of a mobile user with a high degree of accuracy is a trending research interest. It holds the key to a breakthrough in many service challenges faced by operators in the wireless communication industry. With a success in this field, it will be possible for call rates in mobile phones to be charged based on the location a subscriber is calling from; fighting crimes and delivering emergency services through the mobile network’s ability to detect the caller’s po...
ABSTRACT In making a choice of solar Photovoltaic or diesel generator system as an alternative for power generation, life cycle costs (LCC) analysis are considered to be potentially important to such a decision. It incorporates all costs arising from owning, operating, maintaining and ultimately disposing of a project. In this study, a software computer program is developed to determine life cycle cost of solar Photovoltaic and diesel generator systems in Nigeria. The software is developed th...

STRACT Global warming is a serious problem facing the world today as well as the world in the future if left unchecked. In order to stop or avert this problem, our today’s society must change her ways, by learning how to alter what they do or use in order to be less harmful to the environment. Making our buildings and general structural facilities “green” would greatly impact this problem. There are many ways for this to be done and more ways are being developed rapidly. As these new de...
ABSTRACT This research work on “Modelling and Simulation of Leakage-Induced Pressure drops along oil and gas pipelines tends to develop flow equations that can detect and localize leakages in oil and gas pipelines by modifying the Darcy-weisbach equation for liquid/oil flow, and the Panhandle B equation for natural gas flow in pipelines. These modified equations were simulated using matlab to show how flow rate values for the oil and gas pipelines vary when; the pipeline is working at full ...
