ABSRACT The reliability of Power Company Electricity Service varies greatly due to many factors including the design of the power grid, protective features, power system maintenance practices and severe weather. This work is on the design and construction of a l .5KV A Pulse Width Modulated (PWM), Metal Oxide Semiconductor Field Effect Transistor (MOSFET) based Inverter, which works on the principle of Pulse Width Modulation. The inverter uses the IC SG3524 and a pair of six IRFP260N MOS...
ABSTRACT In urban areas, Liquefied Petroleum Gas (LPG) is a leading source of fuel because it is clean compared to kerosene, charcoal and firewood. Due to increase in its use, there is always danger of gas leakage which pose great danger to lives and property due to highly flammable nature of the gas. Cases of gas explosions has been on the rise and thus the need for development of a fast response and high accurate GSM based gas detection system. The developed device is a gas detector us...
Abstract Pulmonary tuberculosis (PTB) is a common worldwide infection and a medical and social problem causing high mortality and morbidity, especially in developing countries. An expert system for diagnosis of this disease was designed based on expert’s knowledge for providing decision support platform to assist fresh graduator (inexperienced) physicians, and other healthcare practitioners to arrive the final diagnosis of TB more quickly and efficiently especially in rural areas. Informat...
Abstract The aim of this project is to design and implement a Matlab based image processing software to extract features of breast cancer images in order to classify disease through neural network in order to examine system accuracy by comparing two techniques of neural networks, feed-forward and back-propagation neural networks. After simulation it was found that the feed forward neural network results are approximately same as the results of back propagation neural network, but from the acc...
ABSTRACT The construction industry in Sudan is an important sector due to its enormous contribution to the country’s economic development. This in terms of employment opportunities and attraction of Foreign Direct Investments which grossly contributes to the country’s GDP. However due to the geographical, political, social and financial situation of the country, many construction projects are prone to delay, cost overrun or unsatisfactory quality, these three functions form the core of ...
ABSTRACT Oil Industry has become the most important part of Sudan Economy and is playing the main role for country incomes. White Nile Petroleum Operating Company (WNPOC) is one of the Oil Operating Companies which has been producing crude oil since 2006; one of its running fields is Mala fields which comprise the following sub fields: • Mala Main, • Mala North, • Mala East and • Mala South East. When these fields were commissioned and started-up, there appeared continuous power out...
ABSTRACT The purpose of this project is to design and implement a digital wattmeter that can measure wattage of a circuit The design is implemented using the microcontroller ATMEGA 8, based on the principle of calculating power mathematically two ATMEGA8 were used, one for measuring current while the other for measuring voltage, the multiplication of the voltage and current values gives the wattage reading. At the end of the process the LCD displays the voltage, current and wattage readin...
ABSTRACT This project presents a single phase inverter system which serves as an alternative power supply. The conversion technique used is first converting the low voltage DC power to AC power using pulse width modulation (PWM), then boosted to high AC voltage using a step up transformer for constant output voltage instead of boosting the low voltage DC power to high voltage power source using a DC- DC booster which is then convetted to AC power using pulse width modulation (PWM). It is ...
ABSTRACT An integration of Vehicular Ad-hoc Network (VANET) and cellular network, e.g. LTE is a promising architecture for future machine-to-machine applications. This integration helps vehicles to have steady internet connection through cellular network and at same time can communicate with each other. However, dead spot areas and unsuccessful handover processes, due to vehicles high speed, can disturb the implementation of this kind of architecture. In this thesis, a Simplified Cluster –...
ABSTRACT This project is about the Design and Construction of a Vehicle Tracking and Accident Alert System (VTAA) using GPS and GSM Technology. It comprises of integration between GPS receiver, microcontroller and GSM module, and of course the push button for accident alert activation. The combination of all this technology wilJ produce our VTAA system. The GPS module receive the coordinate of the point at which the system is located, controlled by the user using command interfaces thro...
Abstract In the present study, a new technology controlled Ethanol/Water mix injection method is applied to a direct injection (DI) diesel engine to show effect on engine performance and emissions under steady operation. Ethanol/water mix is injected into the inlet manifold during inlet period. The experimental test matrix included six different fuels, namely Neat Diesel fuel and five secondary Ethanol/Water mix fuel with diesel fuel. The mixed fuels contain 0.55–2.79 by volume fraction of...
Abstract One motivation of grid computing is to aggregate the power of widely distributed resources and provide non trivial services to users. To achieve this goal an efficient grid scheduling system is an essential part of the grid. The scheduling of the processes can be implemented in different ways with different scheduling algorithms. In this project we use Shortest Job First [SJF] algorithm where it assigns highest priority to shortest process. If processes are long, it suffers with a l...
ABSTRACT The design of the wireless audio and video transmitter was done in stages taking into consideration a pre-selected desired frequency. These stages are the power supply stage, the carrier frequency generation stage, the carrier frequency pre-amplification stage, the voltage controlled oscillation stage and the final stage which is the modulation and amplification stage. First, carrier frequency was generated in the oscillator circuit comprising of an NPN transistor Cl 674, a vari...
Abstract Conventional methods of system load shedding are too slow and do not effectively calculate the correct amount of load to be shed. This results in either excessive or insufficient load reduction. In recent years, load shedding systems have been repackaged using conventional underfrequency relay and/or breaker interlocks schemes integrated with Programmable Logic Controllers to give a new look to an antiquated load preservation methodology. A truly modern and intelligent load shedding...
ABSTRACT This study was carried out on River Atuwara in Ota, Ogun State, Nigeria with the aim of developing a coefficient of re-aeration model applicable to River Atuwara and other rivers in the Nigerian environment. This was achieved by sourcing for data once every month from 22 sampling locations of interest within a pre-selected segment of the river over a period covering the dry and wet seasons. The data collected include hydraulic data (depth, width, velocity and time of travel) and wat...
