ABSTRACTNigeria’s dependence on conventional energy for power needs has been her undoing. Given the limited supply, and inherent dangers, her quest for electrical power self sufficiency has remained a dream. As the inhabitants of the world increases, pressure is placed on almost all the essential commodities for human satisfaction. The continuous supply of power from the national grid to industries and establishments has become a major problem thereby forcing some companies to go for ...
ANTENNA SIMULATION: How to optimize your design. antenna are virtually everywhere from commercial applications such as smartphone,RFID tags and wireless printers, to deference application such as phased array antennas, to provide integral ground based communication systems. electromagnetic simulation is highly valuable tool in antenna design and platform integration. it provides the designer with the ability to virtually design and evaluate 'what if' scenarios as well as ve...
AbstractThis project work focuses on the design and construction of heat detector for use in homes, industries, offices etc. It uses thermistor as the heat sensitive element; which is a type of resistor whose resistance changes significantly according to temperature change. The thermistor was connected as a voltage divider to one input therminal of the comparator (Pin 2) of the 555 timer IC as the resistance of the thermistor increases, the voltage at pin 2 decreases. Thus pin 1 becomes high ...
AbstractThe uninterrupted power is only dedicated for the purposed of illumination. Light is so important to man, so there is need to build an emergency lightening system to help reduce the problem encounter due o frequent interrupted power failure. This is reason for this project report which is CONSTRUCTION OF AUTOMATIC EMERGENCY LIGHTING SYSTEM. These project forms a stand-by source of light energy to man, it operates with the principles that when there is power failure the system will aut...
AbstractDigital (Fan) Regulator is one of the applications of electronics to increase the facilities of life. Fan is one of the unavoidable Electronic equipment in our day to day life. It has become essential element without which people can’t lead a smooth life. The presence of a fan in a house or office is not now considered as a luxury on the other hand it is included in the basic requirement. The uses of new electronic theories have been put down by ex...
ABSTRACTTransient over voltages have often been blamed for the malfunctioning of electrical power systems. This seminar paper is an overview which seeks to describe the state of the power system under transient condition. It also provides information on the rate of occurrence, on the wave shape, and on the energy associated with the transients, as a function of the location within the power system. Also, the basic principles of coordinated protection with specific experimental examples are eq...
ABSTRACTCongestion remains a major challenge to telecommunications service provision both to the service providers as well as the subscribers. This seminar work attempted to determine the causes of congestion and evaluated congestion control mechanisms adopted by service providers in Nigeria using MTN Nigeria as a case study. Findings from the study showed that apart from the carrying capacity of the MTN network other factors such as the use of phones for data transfer and multimedia ac...
ABSTRACTThe general approach to any design of a process plant involve an advanced network of Chemical Engineering processes. This equipment design project was carried out to design a molten salt cooler (heat exchanger) for production of 2.7 x 104 tonnes/year capacity of phthalic anhydride by direct synthesis of gaseous naphthalene.The information concerning the design of this equipment was gotten from literature review which was then used to obtain the physical properties datas. T...
INTRODUCTIONIn today’s quest for electrical energy and increasing hazards in our environment, alternatives to the use of non – renewable and polluting fossil fuels have to be investigated. One such alternative is SOLAR ENERGY. Solar energy is quite simply, the energy produced directly from the sun and collected elsewhere, on earth. The sun creates its energy through a thermonuclear process that converts about 650,000,000 tons of hydrogen to helium every second. The process creates he...
