ABSTRACT This work modified an existing lead-acid battery charging system by developing and simulating the conventional lead-acid battery and the fuzzy logic control of the lead-acid battery charging systems. The fuzzy logic system is developed using Mamdani inference system in Matlab toolbox and Simulink, and consequently employed in controlling the 12 conventional charging system adopted. The output voltage of the battery is controlled using matrix laboratory (MATLAB) in creating Fuzzy Infe...
ABSTRACT Interior Permanent Magnet (IPM) motor is widely used for many industrial applications and has relatively high torque ripple generated by reluctance torque. Since the configuration of the stator has great influence on reluctance torque, different stator configuration is necessary to improve the torque performance of IPM motor. Natural variable modeling and performance comparison of Interior Permanent Magnet Motor with Concentrated winding (CW), Short pitched and Full pitched distribut...
ABSTRACT This thesis is a study of short-term electric power forecasting in the Nigerian power system using artificial neural network model. The model is created in the form of a simulation program written with MATLAB tool. The model, a multilayer timedelayed feed-forward artificial neural network trained with error back propagation algorithm, was made to study the pre-historical load pattern of a typical Nigerian power system in a supervised training manner. After presenting the model with a...
ABSTRACT A single line contingency analysis and generator(s) outages were carried out on 330kV, 27-Bus power network using MATPOWER 4.1 embedded in MATLAB to carry out fast decoupled load flow studies in order to identify the voltage violation at various buses, determine power losses at the transmission lines and to compute the performance indices. The performance indices were further ranked in accordance with their severity index. Voltages less than 0.95pu were assumed to be low voltages and...
ABSTRACT This project presents a quality model of induction motor showing steady state and dynamic analysis using Volt/Hertz open loop, Volt/Hertz closed loop, Slip differences and constant flux methods. The main objective is to maintain the speed at constant rotor flux and to investigate the control schemes for controlling induction machine, particularly the scalar control method and to evaluate their performance under variable input-output conditions. Analysis of the steady state equivalent...
Despite high levels of good quality tomato production in Kenya, about 40% of the produce goes to waste. This loss is attributed to glut during the harvesting season, poor feeder roads which lead to inaccessibility to the market centres as well as bruise damage during transport. This translates to a huge financial loss to tomato farmers. Preservation through drying technology can help in reducing this loss. Therefore, this study was initiated to investigate the performance of an experi...
ABSTRACT Phase change materials have been widely used in optical and electronic storage due to rapid and reversible phase transition between amorphous and crystalline states with remarkable resistivity and optical contrasts. More recently these materials have been identified as suitable candidates for phase change random access memory (PCRAM) applications due to their potential for high scalability, low power and fast speed operation. Despite these superior properties and enormous potential, ...

Abstract With the growing population rate, the amount of waste being produced is also increasing at a very fast rate. These days in our environment waste management is one of the major problems, the best solution has been proposed to solve this problem is segregating this waste and recycle it. But segregating it manually is complex, dangerous and utilizes more human efforts, cost and time. The proposed system designed to separate five types of wastes into respective bins automatically by the...
ABSTRACT In this thesis, an embedded system which is closely monitored and controlled the climate parameters such as humidity, temperature, and light of a greenhouses based on wireless sensor network on a regular basis round the clock for cultivation of crops or specific plant species which could maximize their production was presented. The designed system comprises beside the sensors from microcontroller, monitor, wireless communication based on XBee and respondents such as fan, heater and ...
Abstract Fuzzy logic is a paradigm for an alternative design methodology, which can be applied in developing both linear and non-linear systems for embedded control. One of successful application that can use fuzzy control is liquid level control. This control system keeps developing from time to time to replace the ordinary system which applies mechanical functions in its control in order to improve the system reliability. In order to find the best design to stabilize the liquid level, the ...
ABSTRACT Ability to use electrical energy when required is one of the fundamental presumptions of a modern society, and the introduction of complex and sensitive machines and systems into the network had increased the need for high reliability of supply [1]. Deregulation and competition are forcing improvements in efficiency and reductions in cost while customers are becoming more sensitive to electrical disturbances and are demanding higher levels of service reliability. Since a typical dist...
ABSTRACT The purpose of Maintenance is to extend equipment life time or at least the mean time to the next failure. Asset Maintenance, which is part of asset management, incurs expenditure but could result in very costly consequences if not performed or performed too little. It may not even be economical to perform it too frequently. The decision therefore, to eliminate or minimize the risk of equipment failure must not be based on trial and error as it was done in the past. In this thesis, ...
