ABSTRACT The project is on the tDevelopment of Automobile Br&e Linings using materials and methods. Five dis= brake linings of the geometrical specification of Peugeot 504 series were produced using the available equipment at the Mechanical Engineering Department of the University of Nigeria, Nsuklira, The friction pads were made of varying proportions of palm kernel shell as the base friction material, rubber latex, rubber dust, sulphur, clay, brass chips and Epoxy Resins. Laboratory tests...
ABSTRACT ISRASAT1 is the cube satellite being devolved by the Institute of Space Research and Aerospace (ISRA) to orbits at 450 km above the Earth. The main mission of ISRASAT1 is to take images from space, transmit it to ISRA ground station while transmitting a beacon signal all the time. ISRASAT1 subsystems are the onboard computer subsystem (OBC), electrical power subsystem (EPS), attitude determination and control subsystem (ADCS), communication subsystem (COMM) and payload subsystem (PS...
ABSTRACT The MEMS accelerometer is an important sensor to measure the object’s motion state (acceleration), and it is a key device in inertial systems such as, vibration measurement and navigation systems. MEMS accelerometer has the advantages of high precision and large measurement range, but it suffers from noise problems which results in negative consequences, because of double integration process to calculate the distance which results in erroneous measurements especially when integrat...
ABSTRACT Effect of annealing temperatures and annealing time on the hardness of engineering materials is of great importance which needs c1·itical considerations. This work involves casting Al-6% Cu alloy. Spectroche111ical analysis on the alloy revealed that the alloy mainly contained 91 % alumi11iu111 and 6% copper. After casting, ho111oge11izatioa1n1n ealing was conducted on IO samples of the alloy at 450°C lix I hou1· and the samples were allowed to cool in the furnace. The homogen...
ABSTRACT In this new era, innovation has extended its arm into different aspect of life especially in the transportation field. This development has led to an increase in pr-Oducing smarter vehicles fo1· transportation. Thus, requiring an appropriate automatic washing framework to wash and maintain cleanliness of these vehicles. This project involves the design and construction of a PLC based automatic car washing system with the aim of reducing water waster by incorporating a recycling sys...
Abstract This thesis intends to show the current state of Combined Heat and Power (CHP) Systems and highlights the different aspects of the technologies. The theoretical principals for planning and analysis of a CHP system are described. Economic and technical evaluation was conducted to a CHP system by using Suzuki models. Matlab program were developed in order to investigate on the main factor effects the profit index of CHP systems. These factors include capacity factor, annual cost rate ...
ABSTRACT The objective of this paper is to design, fabricate and experimentally investigate the working of Pedal Powered Centrifugal Pump (PPCP) which is used in small drinking water supply and garden irrigation.PP
Abstract This research aims to analyze and address the technical study Fault Tolerance in controlling the fuel map by predicting the expected failures to occur in the actuators unit the internal system (Fuel Map) and make the necessary compensatory accounts and estimates to ensure the continuation of the work the engine on an ongoing basis with a failure until the failure treatment or programmatically change the system on part if necessary. Through research was to explain the definition of c...
ABSTRACT The demand for energy is becoming a critical challenge for the world as the population continues to grow. This calls for Sustainable energy production and supply such as renewable energy technologies. Renewable energy technologies are safe sources of energy that have a much lower environmental impact than conventional energy technologies. In this paper, the sawdust briquette machine is designed. Sawmill waste is a big problem especially in urban cities in Nigeria. These wastes are b...
Abstract Pump control system is designed to monitor the level of water in the overhead and underground tank through water level sensors, and run the pump only when the water level in the underground tank is up to the position of the water level sensor as long as the overhead tank is empty and automatically turn off the pump after the fullness of the overhead tank where its has two water level sensors. The circuit is made up of (microcontroller Atmega16), three sensors for water level (Float ...
ABSTRACT Numerous failures and eventual losses in the chemical industry have been traced to corrosion processes. Failures resulting from the inability of metals to support designed load requirements because of losses imposed by corrosion effects can be combated economically through the use of chemical inhibitors. Despite the fact that synthetic inhibitors are effective, nonetheless they are associated with problems of toxicity, disposal, litigation and enormous costs. In order to protect the...
ABSTRACT Body amour describes the object that is worn or carried to provide an individual protection against external energy. This research work was carried out to formulate powdered alumina for body amour application. Alumina powder (Al203), magnesium oxide (MgO), calcium oxide (CaO) and polyvinyl alcohol (PY A) were the materials used in the formulation procedure for the research work, the materials were mixed thoroughly to form six different formulation samples; binder and alumina po...
Abstract Competition pressures are forcing manufacturing companies to continuously seek new ways to manage their production capabilities more effectively in order to meet the demands of the market. In addition, to fulfillment of consumer needs and faster delivery times require efficient manufacturing controls and planning to ensure that productivity is maintained, stocks are minimized and resources are optimized. Part of management's drive in an organization is to ensure future sustainabilit...
ABSTRACT Steam boiler is a closed vessel which is used to produce steam from water by combustion of fuel. Steam is important in engineering and energy studies. It is use to sterilize laboratory equipment, for heating applications and also used to generate power. A laboratory fire-tube boiler was design and constructed from a conceptual physical geometry, making necessary design calculations from which dimensions and other deductions were made, and finally developing a working drawing. A b...
