ABSTRACT The paper discusses the solar energy potentials and drawbacks as sustainable alternative energy source for Nigeria, the numerous issues involved in harnessing solar energy and clearly articulates a road map to enable Nigeria tap into this huge potential. Research indicate that, Nigeria lying in the tropics, receives abundant sunshine where about 1500PJ (about 258 million barrels of oil equivalent) could be available to Nigeria annually from solar energy if solar appliances with 5% c...
ABSTRACT The Student Industrial Working Scheme (SIWES) is a program that was designed by the Industrial Training Fund (ITF) with the aim of aiding young science and engineering university students to have an experience of working in industries and companies based on their fields of study in order to extend their learning outside the classrooms and lecture halls. This is a report which contains information about my SIWES experience. It contains details on the company I worked in which wa...
ABSTRACT This report brings to the fore, The Renewable Energy Sources presently accessible to the human species, and the feasibility of harnessing these energy sources in Nigeria. Since the dawn of the 21st Century, Global Warming, Carbon Emission Reductions and Renewable Energy Sources have all been major topics of discussion, permeating into the facets of every socio-economic and political forum such as, Davos Economic Forum, G7 and G20 Conventions, and has spawned specific platforms for di...
In democratic countries, voting is an vital tool to collect and re-act people‘s views. In the elections, the election of member of the assembly, the head of local/state government election, and others, a voter can cast vote after going to the designated polling place and checking his identity. Conventionally, voting booth is used for casting votes in both centralized and distributed places. Voting is done under the supervision of authorized parties. Counting of votes is done manually once...
ABSTRACT: This work entails design, construction, packaging and evaluation of a prototype automatic a.c. voltage stabilizer using parallel cascaded relays. The unit was cascaded to provide more switching contacts on the auto-transformer. The overall system design is a compact assembly encased in a portable metal box with handle which can operate on 90v minimal input voltage. In this paper, a parallel cascaded relay what is essential was implemented in the design of voltage stabi...
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...
