Abstract Machines are very important in modern society. The bearing compose a supreme component in the machine parts ,hence, many problems arise that minimize bearing life like high temperature, speed and excessive vibration. In this research, electronic simulation system is developed to measure temperature, speed, and vibration in deep groove ball bearing. Hence, the system live alarms and sends signal to stop the machine when it exceeds one of three-designed value. This system was tested i...
Abstract Picking and placing an object or products in specific place or boxes play an important part in industry process, it consumed a lot of time also need patience and accuracy and cannot handle any mistakes. Pick and place robot is a robot that can be programmed to pick product or any object and place it somewhere. these robots are popular among many automation applications and material handling system, they are especially practical in applications where repetitive and difficult tasks ne...
ABSTRACT The objective of this research is to identify the methods to improve current inspection and evaluation strategies for medical devices in health facilities. The research aims to emphasize the effect of proposed model variables (documents, visual inspection, risk management, preventive maintenance, performance indicators, corrective maintenance, inventory management, policies and procedures and vocational performance) on the dependent variable (the development of health care). The mos...
ABSTRACT With the fast depletion of fossil fuel sources for energy production and coupled with their negative impacts on the environment, the continued search for alternative sources that are renewable, sustainable and environmentally friendly has become imperative. This research examined the performance of sodium borohydride for the production of hydrogen gas using 5 ml each of organic acid (acetic acid) and extracts of spoilt citrus fruits (lime, lemon and orange) without the use of neithe...
ABSTRACT Liquid column that accumulates in the wellbore leading to the reduction or completely preventing the production of gas well is called liquid loading. This is one phenomenon that is essential because in other to optimize the recovery of hydrocarbon from the gas reservoir and to prevent the occurrence of liquid loading, pressure differential as a function of flow rate across the valves must not be neglected. Several options have been employed in well completions to predict liquid load...
Introduction Excellencies, distinguished guests, members of the Press, ladies and gentlemen, this is a unique day and unique occasion for me. In the first instance, it is a singular honour and privilege to be given this rare opportunity to address such a distinguished audience on the sore issue of poverty in Africa that has agitated my mind for several years now. But most importantly, today happens to be the birthday of our Chancellor, Dr. David Oyedepo, whose passion, vision and raison d'et...
INTRODUCTION. In its ordinary sense, the term destruction usually has the under current of sadness. Why then would destruction in this context be beneficial to the socio-economic well being of the human race? The reasons will crystallize out. I hope, as I discuss this topic. The black gold simply refers to crude oil or petroleum, its offspring are the products resulting from its destructive physical separation. One may then ask why the name “black gold”? Gold as we know is a very expensi...
ABSTRACT The purpose of Maintenance is to extend equipment life time or at least the mean time to the next failure. Asset Maintenance, which is part of asset management, incurs expenditure but could result in very costly consequences if not performed or performed too little. It may not even be economical to perform it too frequently. The decision therefore, to eliminate or minimize the risk of equipment failure must not be based on trial and error as it was done in the past. In this thesis, ...
INTRODUCTION In west African and other tropical countries cassava tubers are a source of major staple foods. They are also used in the .manufacture of ethyl alcohol and the production of starch used as a binder in tablet making and as an animal feed, and are being proposed for use as an addition to wheat flour for bread making. Corrosion of mild steel machinery, storage facilities, and agricultural implements used in processing cassava roots has been widely reported by the processing industr...
ABSTRACT A PLC is a digital computer used to automate electromechanical processes. PLC is frequently used when implementing automated control, which is an important part of many modern industries. This research is based on monitoring Level Temperature Pressure Flow and water cut of crude oil in the vessel by using ABB Programmable Logic Controller . Automatic control of crude oil in vessel can work continuously and can provide accurate quantity of crude in less time. In such process there is...
ABSTRACT The performance of Butan-1-ol (BTU) on the pitting corrosion inhibition of austenitic stainless steel (Type 304) in dilute sulphuric acid contaminated with recrystallized sodium chloride was investigated with the aid of potentiodynamic polarization technique. Corrosion potential, pitting potential, passivation potential, nucleation resistance, passivation range, passivation capacity measurements and potentiodynamic analysis were used to assess the pitting resistance characteristics ...
INTRODUCTION First of all, I like to thank God for this opportunity to stand before th all of you this afternoon to deliver the 29 in the series of Public Lectures organized by Covenant University. I like to thank the Chancellor, the Vice-Chancellor, the Registrar and all members of Management for giving me the opportunity to use this platform to express my views on the issue of Infrastructure development in our country and continent. Secondly I like to acknowledge my faith in God and in his...
REACTIONS AND TYPES Reaction in chemistry has to do with a chemical transformation taking place with atoms or molecules (compounds) or their combinations. Since there is usually a change in energy level, reaction is usually accompanied by heat absorption (Endothermic Reactions) or heat evolution (Exothermic Reactions). On a daily basis, apart from reactions that are initiated by man, there are scores of natural reactions taking place on routine basis. The existence of man and other living th...
ABSTRACT This study pursuit develop solar energy systems in the light of technological advances to develop these systems, especially those moving (solar Tracking) to take advantage of sunlight for a longer period. The Objective of Thesis is to find a design of the sun Tracker with two axes follow the movement of the sun throughout the sunrise to take advantage of the rays and solve the problem of environmental factors and the alternation of night and day to produce the greatest amount of sol...
ABSTRACT Power system stabilizers and other controllers are employed to damp oscillations in power systems, thereby guaranteeing satisfactory dynamic performance following major network disturbances. However, the parameters of these controllers are often tuned based on the power system linearized model which generally is a function of the system operating point or state. These controllers suffer from poor performance when the system state changes. The aim of the research work reported in thi...
