Abstract Ashesi University College is faced with the challenge of effectively scheduling courses at the beginning of the semester so that there are no class clashes for both lecturers and students. In an attempt to solve the Course Timetabling Problem at Ashesi University College, five algorithms: Genetic Algorithm, Constraint Programing, Particle... Continue Reading

ABSTRACT Lecture timetabling is a very important process in any educational institution. It is an open-ended program in which courses must be arranged around a set of time slot ’T’ and remains so that some constraints are satisfied. It constitutes a class of difficult-to-solve optimization problems that lacks analytical solution method. Data... Continue Reading

Abstract This thesis aims to extract d-axis machine parameters of a 214 MVA high-speed turbogenerator using well-established offline techniques. MATLAB/SIMULINK tool has been utilized to model the generator and perform sudden short-circuit (SSC) tests. Because constant speed operation of the generator is vital consideration for the accuracy of SSC... Continue Reading

Abstract In this work, a 2.8kva alternator was coupled to a 4 H.P dc motor acting as a prime mover to produce a fuel-less generator. The coupling was done using two crankshaft pulleys to match the speed of the alternator to that of the dc motor. Two 24v dc deep cycle batteries were also used as the exciter unit and a sustainable output voltage of... Continue Reading

DESIGN AND MANUFACTURE OF A FUEL-LESS GENERATOR ABSTRACT The fuel-less generator is a flywheel energy storage system (FESS) which has attracted new research attention recently in applications like power quality, regenerative braking and uninterruptible power supply (UPS). As a sustainable energy storage method, flywheel energy storage has become a... Continue Reading

Abstract The university libraries are libraries established to cater for the academic and research needs of the university. They serve the reading and research interests of undergraduates, lecturers, researchers, and other users. University libraries are big repositories of information and knowledge from all fields of learning to the academic... Continue Reading

ABSTRACT  A drastic change in the perception of electric energy . But at the same time there is misreading of FREE ENERGY. Energy becomes free only at a point after which we don’t have to pay for power generation after hiring the unit. By using the magnetic force of magnets continuous motion (Energy) is made. This magnet also produces a... Continue Reading

ABSTRACT As technological advancement has been on the increase in our society many have fallen in love with technology and world want to have a feel in virtually to every thing they do. A design has been made in combination of electrical and electronics to change over from one power sources to the other automatically and trip off generation after... Continue Reading

CHAPTER ONE INTRODUCTION 1.1       Preamble A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). ( The Authoritative, 2000 ). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The... Continue Reading

DESIGN AND CONSTRUCTION OF AN AUTOMATIC CHANGE OVER SWITCH WITH GENERATOR CUT OFF AND STARTER ABSTRACT Power supply in Nigeria and most developing countries of the world is anything but stable. This has adverse effects on the consumers of the electricity and the equipments that are operated from the mains sources of electricity supply in these... Continue Reading

Abstract Producing software compels programmers to have in-depth knowledge of several programming languages, tools and frameworks. This time-consuming process demands dedication and mastery which are typically the foremost reasons most novice programmers give up a little into the software development process. This project seeks to eliminate... Continue Reading
