ABSTRACT: This project design is simply used to display the items demanded by each customer on the table. Each table has four buttons for Rice, beans, amala and akpu, and each of the buttons are connected to the processor. The customers on every table presses the button with the label of the item he or she needed. Then, a screen in the kitchen is used to display the table number and the items demanded. The major components used in this design are 8951 microprocessor, crystal o...
ABSTRACT Natural Disasters or Natural Calamities, whatever you name it has for long been the most dreaded cause of mass destruction and loss of human lives, wealth and property. It destroys the beauty of earth, lives of humans and leave behind no traces of existence. It’s so severe in its approach that millions and billions of people and land vanishes and escape into oblivion in just a moment. But nothing fruitful or beneficial could be done as most of the people thought that these d...
Abstract Digital (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 expertise to increase the fa...
INTRODUCTION:The main objective of this project is to develop an Automatic Door opening system using IR sensors which will reduce the need of manual labor.Automatic door opening systems using IR sensors plays a very important role in domestic applications. The elimination of manual supervision adds up as an additional advantage for its usage. Its significance can be proved by considering the following specialties of kit designed.
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 ...
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...
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 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...
