ABSTRACT The Electric Power and Energy Systems (EPES) group forms a core research area of the Department of Electrical and Information Engineering. Our research cluster is motivated by the need to address the issues related to the design and operation of modern, “smarter”, greener electric power grids. In addition, renewed interest in hybrid--‐electric distributed systems and home automation calls for advances in the area of energy conversion and power electronics. The EPES research c...
Abstract Over the past several years, the Internet environment has become more complex and untrusted. Enterprise networked systems are inevitably exposed to the increasing threats posed by hackers as well as malicious users internal to a network. IDS technology is one of the important tools used now-a-days, to counter such threats. The goal of intrusion detection is to identify unauthorized use, misuse and abuse of computer system insiders and outsiders penetrators. Various IDS techniques ha...
ABSTRACT Failure of engineering components in service, especially in marine applications, has recently been a major global concern, and corrosion resulting from biofouling has been the primary source of these failures. Ultimately, biofouling and corrosion are detrimental to the lifespan of parts in service. Thus, there is a need to develop protective coatings which are highly resistant to the biofouling-corrosion system. This study developed affordable, eco-friendly and durable bi-phase of Zn...
ABSTRACT African nations have been characterized by conflicts, total war, slave trade, poverty of the highest order, corrupt leadership, undeveloped infrastructures, indisciplined society, we can go on to mention as many as the vices that estranged the continent. It is an irony to see all these in African continent, where civilization of the world began. For all these calamities that befell Africa, I sometimes wonder, if that is why the observation of our God in Genesis 6:5 was made. “The L...

The computational model simulation development was use the commercial computational fluid dynamics of GT-POWER 2016 software were specially development for internal combustion engines performance simulation. The research concentrated on th...
ABSTRCT Materials have been the milestones of progress. All civilizations have been categorized by the materials they used; The Stone Age, The Gold Age, The Silver Age, The Bronze Age, The Iron Age, etc. Some of these periods in history lasted centuries but in recent times both the rate of major materials breakthroughs and their improvements are increasing ever faster. Materials are constituents of the earth and the earth is materials. In Genesis 2:1, it reads: “In the beginning, God crea...
Abstract The Use Of Ferrous Gluconate As Corrosion Inhibitor On Aluminium Alloy In 0.5M H2SO4 Solution Was Studied Using Gravimetric And Potentiodynamic Polarization Measurements. The Surface Morphology Of The Aluminium Alloy Was Studied After Exposure To 0.5 M H2SO4 Solution In The Presence And Absence Of Inhibitor Using High Resolution Scanning Electron Microscopy Equipped With Energy Dispersive Spectroscopy (HRSEM – EDS). The Adsorption Behaviour Of The Inhibitor Was Investigated. T...
ABSTRACT Zeolites are important chemical materials used in chemical processes. The manufacture of the materials usually involves the use of expensive chemicals. This study involves the use of Elefun Nigerian Kaolin (ENK) as precursor material for the development of zeolite Y. The synthesis of zeolite Y was successful following a sequence: collection of raw kaolin clay from Elefun area of Ogun state, Nigeria; subjecting it to, calcination, partial dealumination and final hydrothermal syn...
ABSTRACT Electricity, of which Light is a product is the whole essence of life. This informed God's decision to command light into existence before the creation of all other things. Unfortunately, the undertakers of our electric power sector will not allow this beautiful idea of God to work in this country [2]. Electricity is not a primary source of energy; however, it is one of the most versatile forms [3]. It is known to play a significant role in the advancement of the standard of life of ...

ABSTRACT In this study, a nonlinear dynamic model for large scale fossil fueled boiler turbine power generation units is presented. The challenge in controller design for these plants exists because they are typically nonlinear and multi-variable with multiple control objectives. This thesis presents the application of a fuzzy logic based controller for boiler turbine plant to control the drum pressure, power output and water level. Fuzzy control system have been successfully applied to a wi...
ABSTRACT The Stone Age, The Gold Age, The Silver Age, The Bronze Age, The Iron Age, etc. Some of these periods in history lasted centuries but in recent times both the rate of major materials breakthroughs and their improvements are increasing ever faster. Materials are constituents of the earth and the earth is materials. In Genesis 2:1, it reads: “In the beginning, God created the heaven and the earth”. So the earth was either created simultaneously with the heaven or it was c...
ABSTRACT The proposed methods to solve optimal control problems are classified as direct methods and indirect methods. This thesis is based on solving optimal control problems using direct methods in which an optimal control problem is converted into a mathematical programming problem. The direct methods can be employed by using the parameterization technique which can be applied in three different ways: control parameterization, control-state parameterization and state parameterization. Her...
Abstract The objective of this research is focused on the vortex flow in Kaplan turbine runner - a tip vortex. CFD analysis was performed to predict the water flow inside the turbine for more diagnosing and investigation of the hydro power problem. On the basis of this analysis it is possible to estimate the existing and the intensity of vortex, danger of possible blade surface and runner chamber cavitations’ pitting and power losses. In the research, the ways how to predict vortex flow an...
