ABSTRACT The design and construction of s refrigerating unit is handled from the knowledge of the working principles of laws of thermodynamics. The size of the containing vessel i.e the case as established to be of 45cm by 32 cm in dimension. The Angle iron mild steel to used in the fabrication and welding. The box case of two layers are fabricated. Plastic (cooler) box is then placed inside the upper part with the other parts of the refrigerator were brought in. they were all fixed onto a...

ABSTRACTA paint mixer is defined as a pattern constructed for the production (mixing) of paint manually. The method of fabrication of the paint mixer involved a preliminary computation of the dimensions of the standard mixer in relation to the dimension of the reacting vessel in which they will be used in marking out, cutting out to sizes, rolling, folding, welding, body-filling and painting. The first step taken in the fabrication of this project work was the selection of material ...
ABSTRACT Nigeria’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 gen...
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 verify the fin...
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...
INTRODUCTION TO SMART CARDS It has been said that smart cards will one day be as important as computers are today. This statement contains a bit of an error because it implies that smart cards are not computers, when in fact, they are. Because smart cards are indeed tiny computers, it’s difficult to predict the variety of applications that will be possible with them in the future. It’s quite possible that smart cards will follow the same trend of rapid increases in processing power that...
ABSTRACT Energy is of great importance to the world at large. It is very important to every nation for growth and development as it is a driving wheel for technological advancement. It is to this end that good management and audit should be inculcated to make sure that this energy is utilized and sustained. This work centers on techniques and measures involved in management and ascertaining good audit. TABLE OF CONTENT Page Title page i Certification ii Ackno...
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...
Abstract This seminar is designed to make home automation easy to control when a user is not at home. The paper is designed to allow easy use of a mobile phone to control appliances in the home. Using a mobile phone the development of the control system will be carried out using SMS. This will communicate with another mobile phone, which in turn controls the devices attached to microcontroller modules. When the action has been carried out then a response is sent to the user. The p...
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 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...
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 Cloning of Computer System is very essential in a computing area. This project focuses more on how computer system could be coupled and maintained effectively and efficiently without any fault during assembling of the system. Throughout this project we shall focus on each and every components needed for assembling and also there functions. The main reason why people go for assembling of system instead of buying a new system is to allow them to have good and satisfactory q...
