INTRODUCTION Planned maintenance apart from programming inspection, should include monitoring, logging, periodic checks and tests of system as to guarantee correct day-today hitch free functioning and control of “closed circuit” water systems to maintain trouble-free operations.This first requirement for any maintenance system planned or otherwise is to compile an inventory of all plants and equipment to be maintained. Besides, additional information must be readily obtained from the manu...
INTRODUCTION Nigeria is characterized with large expanse of land with remote, isolated communities located at long intervals whose inhabitants are often peasant farmers living below subsistence level these areas are marked by lack of basic infrastructures like road network, telecommunication, water supply and electricity etc. Electricity supply in the country has been through centralized generating station (hydro and thermal) with high capacities (above 100MW). The major operators in the Nig...
INTRODUCTION Since the 1970s, energy crises have been reported across the world. In Nigeria Chendo (2001) reported that national energy supply is at present almost entirely, dependent on fossil fuels and fire wood. Also, Akinbami (2001) also observed that the total energy consumption in Nigeria comprises of 5.22% of natural gas, 3.05% of hydroelectricity, and 50.45% natural gas, 3.05% of hydroelectricity, and 50.45% of fuel work. Meanwhile, Ozean Journal of Applied Sciences 4(3), 2011 252 Ali...
INTRODUCTION Energy for obvious reasons is regarded as the prime mover of any economy, and the engine of growth around which all sectors of the economy revolve. Thus, it becomes imperative that its development, management, and improvement must have predetermined plans and strategies that are capable of driving the economy towards a sure path of sustainable development .West African region has one of the lowest per capita consumptions as far as energy is concerned. On the other hand, the energ...
Introduction This is the design and construction of a light sensitive circuit which when the sensor is blocked will activate the light emitting diode at the output. The output gain depends on the non-inverting input of the operational amplifier used in this demonstration. This system is made of different component which aided in the functionality of the design. Aim and Objective In this paper we are to design and construct a light sensitive circuit which senses an obstruction in the sensing ...
INTRODUCTION Digital systems design teams are facing exponentially growing complexities and need processes and tools that reduce the time needed to gain insight into difficult system integration problems. A digital system is a data technology that uses discrete (discontinuous) values. By contrast, non-digital (or analog) systems use a continuous range of values to represent information. Although digital representations are discrete, the information represented can be either discrete, suc...

This is a paper about generating sequences with matlab A digital signal processor (DSP) is a specialized microprocessor (or a SIP block), with its architecture optimized for the operational needs of digital signal processing. The goal of DSPs is usually to measure, filter and/or compress continuous real-world analog signals.1.1Generation of Discrete Time SequencesProject 1.1: Delayed Unit Sample SequenceA unit sample sequence is a sequence that has a value of one (1) at n=0, and a value of ze...
ABSTRACTOil spillage which can simply be referred to as the release of oil into the environment (land or water) either through a deliberate act, accident or as a result of equipment failure indeed has an alarming effect on the affected communities due to the fact that it either renders the environmentuseless or sometimes take a longer time for the affected area to have a natural process of attenuation.In addition, having given the necessary compensation to the affected communities in line wit...
ABSTRACTThe rapid increase in energy consumption particularly in the past several decades has raised fears of exhausting the globe’s reserves of petroleum and other resources in the near future. The huge consumption of fossil fuels has caused visible damage to the environment in various forms. Approximately 90% of our energy consumption comes from fossil fuels. Due to industrializations and population growth our economy and technologies today largely depend upon natural resources, which are...
ABSTRACTEnergy conversion engineering (or heat-power engineering, as it was called prior to the Second World War), has been one of the central themes in the development of the engineering profession. It is concerned with the transformation of energy from sources such as fossil and nuclear fuels and the sun into conveniently used forms such as electrical energy, rotational and propulsive energy, and heating and cooling. A multitude of choices and challenges face the modern energy conversioneng...
ABSTRACTThis report is intended for a general insight into cryogenics. Different individuals may have faint ideas about what cryogenics are as much is not known here in Nigeria about what cryogenics are and this report work clearly gave a deeper knowledge of cryogenics Chapter one gives a brief history of cryogenics and the various cryogenic temperatures that have been achieved since 1800 to 1965. Chapter two gives a general knowledge of the fundamentals of cryogenic engineering...
ABSTRACT This technology is so helpful in our everyday life. This paper dealt extensively about the latest technology which is useful for finishing materials with a very high precision. These latest processes are known as Advanced Fine Finishing Processes. In this paper, we gave a thorough insight into some of these processes. With the demand of stringent technological and functional requirements of the parts from micro- to nano-meter range, evolution of ultra-precision finishing processes ...
ABSTRACT In recent times, most of the household appliances are using electric power and as such, electricity shortage has become a major problem throughout the world. Ceiling fan is one of such appliances that consume electric power. The best way to minimize the power consumption of the ceiling fan is to reduce the weight of the ceiling fan blade. Thus, this project work entails the design of a new ceiling fan blade in which case the weight and power consumption was compared to the Panasonic ...
