Abstract: Series hybrid electric vehicle (HEV) formed by a combination of internal combustion engine and batteries/ultra capacitors in the appropriate ways, provides high-performance and high efficiency power systems for HEV applications. This paper discusses the performance characteristics of series HEV using advanced vehicle simulator. Different sizes of motor and engine were utilized with various battery capacities to explore the optimal component combinations. A comparative simulation was...
ABSTRACT One of the most important resources of a nation is energy. The significance of energy definitely cannot be overemphasized as it is immensely utilized in our everyday activities as a very germane requirement for survival and robust lifestyle. The amount of energy availability and its usage in a country measures the level of industrialization. Several devices including machines, electronics, household electrical appliances and other domestic equipment and machines, industrial pro...
Abstract Energy is one of the major drivers for the economic development of any country. In order to reduce energy consumptions for sustainable development, continuous energy audit of industrial machines become necessary. Energy audit is one of the most comprehensive methods in achieving energy savings in industry and thus reducing excessive energy consumption. This paper analyzes energy auditing in power system in or...
ABSTRACT Cuckoo search algorithm (CSA) is an effective and highly reliable swarm intelligence basedoptimization approach. It is a technique of determining the most efficient, low cost and reliable operation of a power system by dispatching the available electricity generation resources to supply the load on the system. This paper presents a comprehensive review of CSA application in Economic Load Dispatch (ELD) problem. This review will assist po...

ABSTRACT For the past few years, the oil and gas industry has faced several economic, geographic and technical challenges largely due to decline in crude oil prices and market volatility. In the quest to address some of these challenges to accelerate production and subsequently maximize ultimate recovery, operators are limited to remote hydraulic and electro-hydraulic monitoring and control of safety valves providing the means of obtaining downhole production data which demands peri...
Sustainable energy sources have been a topic of interest over a period of time for many researchers. Nuclear energy is one of the sources that have long been exploited for generating heat and electricity both in large scale and small scale. One of the methods for converting this heat into electrical power is using thermoelectric generators. Radioisotope thermoelectric generators are currently the longest-lived sources of energy; it does not require any human maintenance or refuelling. This pa...
Abstract: Melon dehusking is often associated with lots of manual labour and stresses. In order to reduce the stress and boredom usually involved in manual dehusking of melon process, a melon dehusking and separation machine was designed, constructed and tested for operation as presented in this paper. The melon dehusking machine operates on the principle of attrition/friction as opposed to the use of an impact force in the dehusking chamber for shelling of melon seeds. This principle resu...
According to the Sustainable Development Goals (SDG) ‘s indicator baseline 2017 report of South Africa, the percentage of the population using safely managed drinking water services has remained more or less constant around 91% between 2014 and 2016. The observation of the same variable from 1996 to 2011, shows a significant increase from 76.6% to 89.4%. This therefore means between 2011 and 2016, the change has been insignificant. To have a sample analysis in this regard, on the dynamics...
A paper on Electronic Source Code Plagiarism Checker/Detection This paper covers a few algorithms used in an attempt to detect plagiarism among students’ computer program source codes electronically, that is, using a computer software program. One algorithm proved to meet most of the requirements with acceptable results and was implemented using VB .Net programming language. Keywords: plagiarism detection, source code, kheme, source code plagiarism detection, plagiarism detector, source...
CHAPTER ONE INTRODUCTION1.1 BACKGROUND OF THE STUDY: trolling body weight, reducing the chances of heart diseases, reducing the risk of diabetes and some other chronic diseases by improving the functions of the heart, lungs and improving the biomechanical system of the body. Aside surgeryand medication, several methods have been proposed for the prevention and treatment of heart conditions. One of such methods is the use of regulated and supervised exercise as therapy both for prevention of ...

ABSTRACT The presence of methylene blue (MB) in wastewater is a major concern in the environment due to its low biodegrability and harmful effect on man. The treatment of effluent containing such dye is important where adsorption on activated carbon (AC) produced from agricultural waste is of great choice. Optimization of the removal efficiency of MB from aqueous solution onto AC prepared from mango shell was investigated. The AC was prepared from mango shell, activated with BaCl2 at I.R (0.0...
Abstract The ever-increasing rate of failure of engineering students in engineering mathematics is one which the school management and entire stakeholders need not wink at any longer. Engineering mathematics is a prerequisite for all engineering discipline. It equips the student with problem solving skills and cognitive ability needed for higher thinking. The research was conducted to investigate and critically analyze the causes of the recent poor performance of engineering students in ...
Abstract: Wireless power transfer system charging multiple devices, through inductive coupling method which is classified under near field transfer region. In this project, we intend to achieve wireless power transfer charging multiple devices such as mobile phone, toothbrush and other low end power devices without the use of conventional copper wire or cable between the transmitter module and receiver module. In t...
