Abstract To fulfill the need of higher bandwidth, enhanced number of users, enhanced speed of communication of today’s users, the concept of wavelength division multiplexing (WDM) and fiber optic are developed. In which the multiple input signals are combined together and transfers as a single input. It uses the concept of multiplexing and de-multiplexing. WDM system comprises of amplifiers that are used to enhance the performance of the optical fiber system. This study analyzes a hybrid c...
ABSRACT Hypertensive-patient monitoring usually requires the use of non-invasive sensors that are hardwired to bedside monitors. This set-up is cumbersome, forcing the patient to be confined to his hospital bed thereby not allowing him to move around freely within the hospital premises. Presently, in order to continuously track a patient's Blood Pressure (BP) remotely over a period of time, physicians hand over specialized devices to patients. Most of these devices are cuff-based that are wo...
ABSTRACT This project presents the design and construction of a microcontroller based Automatic Transfer Switch (ATS) for a single phase system. The ATS, which is based on a switch gear control system, gives a functional system that provides an automatic switching of power supply between a primary source (public utility) and a secondary power source (generator). The methods employed in designing the ATS involve the use of switching and power relays, Atmega8 microcontroller, diodes, resis...
A web-based information management system for national health insurance scheme(NHIS) will assist the body to have an online registration of people, health maintenance organizations (HMOs), accredited heath care providers, etc. Looking at the Nigerian population, access to health insurance is denied to a certain category of people as a result of not being a government worker or not privileged to be duly informed on the operation of the scheme and how to enroll Knowing that Health insurance is ...
ABSTRACT This report presents a design and implementation of a microcontroller based remote controller for fan and lighting system with LCD indicator. It enables the user to switch ON and OFF the fan and lighting system from approximately 6 meters. The entire system is based on microcontroller that makes the control system smarter and easy to modify. The system ranges from a power supply unit to the control unit and the display unit which indicates when the system is turned ON or OFF. ln...
Abstract : IX The way people perceive the city’s elements at night is totally depends on lighting design and man-made facilities. Due to the development of cities’ economic and citizen’s life style, the nightscape of the city became as important as the appearance of the city at daytime and sometimes it is more important because it can make more impact on people’s minds about the city. Though the potential of Khartoum city to become an iconic lighted city on the Nile river, the city a...
Abstract In Long Term Evolution-Advanced heterogeneous networks, pico-eNBs are added to existing macro cells networks that contain macro eNBs in order to offload traffic from macro layer and bring users closer to the picoeNBs to enhance the cell edge user experience. Moreover, Cell Range Expansion (CRE) is a way to increase the percentage of users that associate to pico BSs which leads to reduce the imbalance traffic load between cells .However, there is strong interference which is caused b...
ABSTRACT Digital intercept receivers are currently moving away from Fourier-based analysis and towards classical time-frequency analysis techniques, such as the Wigner-Ville distribution, Choi-Williams distribution, spectrogram, for the purpose of analysing Low Probability of Intercept (LPI) radar signals.The LPI signals are difficult to detect, intercept and recognize, because they have many combined features implemented that help the LPI radar prevent its detection by modern intercept rece...

The metal detecting systems is a microcontroller based system. This metal detector make use of microcontroller for it operation as well as other components such as: comparator, voltage regulator, operational amplifier. transistors etc .. For this project, the metal detector is built in a way that a metal sensor (culprit oscillator) senses...
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 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 –...
