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 ...
ABSTRACT Transient 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 e...
ABSTRACT Security is a prime concern in our day-today life. Everyone wants to be as much secure as possible. An access control for doors forms a vital link in a security chain. The microcontroller based Door locker is an access control system that allows only authorized persons to access a restricted area. The system is fully controlled by the 8 bit microcontroller AT89C2051 which has a 2Kbytes of ROM for the program memory. The password is stored in the EPROM so that we can change it at any ...
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...
ABSTRACT Congestion 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 activ...
ABSTRACT The project work titled Design and construction of a metal detector. When fully design and implemented would be able to detect any metallic material that is passing or coming close. This function would serve as a security check for dangerous metallic material as an alarm. Going by the sophisticated means of armed rubbers adopt these days in the breaking into bank supermarkets offices and highly secured area. No security system will be optimised or complete without the installation of...

INTRODUCTION This research work introduces the society to voice recognition technology and its usefulness. It serves as a research work for both students and researchers to ease related topic. As technology increases, speech recognition systems have added to the development of the society in the sense that it has increased communication in the society.
ABSTRACT Digital electronics is now used in all fields of electronics from computers to digital phones and most industrial machines and motor vehicles. When prototyping digital electronic circuits, specific digital input signals are required to design the digital circuit. To accomplish this task, a teaching device known as a “Digital Trainer” is utilized. The purpose of this project work is to provide a method for students to test digital circuits, with a simple and inexpensive digi...
ABSTRACT This project work is focused on the design and construction of obstacle detection system for the visually impaired. This paper reports on a study that helps visually-impaired people to walk more confidently. The study hypothesizes that a smart walking stick that alerts visually-impaired people over obstacles in front could help them in walking with less accident. The aim of the paper is to address the development work of a walking stick that could communicate with the users th...
ABSTRACT Since one of the problem of our country Nigeria has been inconsistency power supply, as many business center today depend on computer controlled system, high technology equipment and needs a precise and constant power supply. This work is focused on the design and construction of uninterruptable power supply due to the rising domestic and commercial need for additional back-up source meant to minimize the problem associated with processing, disruption and distribution of val...

ABSTRACT Demulsification (emulsion breaking) is necessary in many practical applications such as the petroleum industry, painting and waste-water treatment in environmental technology. Chemical demulsification is the most widely applied method of treating water-in-crude oil emulsions and involves the use of chemical additives to accelerate the emulsion breaking process. The effect of chemical demulsification operations on the stability and properties of water-in-crude oil emulsion...
