Global System for Mobile Communication (GSM) is a telecommunication network that is used globally for communication services such as voice communication, data connection for fax, short message service (SMS) and full dial-up connection to the internet for e-m…
This research work set out to develop decaying exponential models for predicting the setting time of concrete as a function of its penetration by proctor needle using common sugar as the admixture. Various percentages of sugar by weight of cement (0.01% —1%)…
DECISION SUPPORT FRAMEWORK DEVELOPMENT FOR FLOOD PLAINS IN NIGERIA (A RISK BASED APPROACH)
PUBLISHEDWater we all know is the most vital and prominent need of man. However, its unbelievable effect in 2012 across the whole of West Africa showed that it can also cause untimely death, havoc, disaster and poverty when in excess. The Nigerian hydrological servic…
Dam projects are very costly projects all over the world. Also, in case of dam failure, the effect is always catastrophic and devastating. This leads to loss of human lives and devastating environmental effects. In view of these, it is required that dam proj…
Power system engineers face difficulty in economic operation of large inter-connected power systems. Economic Load Dispatch (ELD) of large inter-connected power system is complex, constrained and non-linear problem which require rigorous and complex calculat…
The research addresses the hydrophilic behaviors of the natural ukam plant fiber material at various studied conditions. The aim of this work was to reveal the possibilities to model the liquid water absorption characteristics of untreated ukam fiber which a…
The paper deals with the design optimization of voltage source inverter (VSI) fed squirrel cage induction motor. A set of nine independent variables were selected and to make the machine feasible and practically acceptable, certain constraints were imposed o…
This study investigates the effect of the various process conditions such as temperature, extraction duration, particle size and solute/solvent ratio on the seed oil solvent extractions using ethanol, n-hexane and methanol/chloroform (50:50) as solvents from…
The shortfalls of fossil fuel, rapid depletion of reserves, nonrenewable, non-biodegradable, low lubricity, emissions of poisonous gases have resulted in the search for alternative energy source to fill the gap. This research work focused on synthesis, engin…
Statistical Quality Control (SQC) analysis deals with quantitative data; it is also a scientific method of analyzing masses of numerical data so as to summarize the essential features and relationship of data in order to generalize from the analysis pattern …
This work addresses the gully erosion problems of the Nanka/Agulu area of Anambra State, Nigeria. Field reconnaissance and observation visits were made to five (5) major erosion sites in the study axis between the months of November, 2011 and February, 2015 …
VARIOUS TYPES OF INSULATORS USED IN POWER SYSTEM FOR SAFE OPERATIONS OF THE TRANSMISSION LINES
PUBLISHEDOverhead bare conductors on steel towers or concrete poles are utilized in transmission and distribution of bulky electric power. These conductors are bare and do not have any insulated coating over them. To ensure safe operation of the lines, a necessary cl…
