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...
Abstract The development of technology has a good impact on all sciences including medicine. The use of modern technology in medicine reduces the incidence of serious medical errors; some diseases need to follow their symptoms for a long time to be discovered. There is a problem in tracking symptoms for patients at each time visiting the hospital where data cannot be saved and retrieved when needed. By using the cloud computing technology, all hospitals can be linked by the Software-as-a-Ser...
Abstract This research concerns with the energy resources in Sudan. It includes the steam plants, their unplanned outage problems. The study conducted on Dr. Sharief power station in Khartoum north. The research is studied the station problems occurring during the period (Jan 2011 to Dec 2015), the maintenance program procedure and management method description. Losses resulting from unplanned outage were calculated. The rest of maintenance was not calculated because there were no enough dat...
ABSTRACT This thesis presents a neuro-fuzzy controller design for speed control of Direct Current (DC) motor. The thesis scope includes the simulations and modeling of DC motor, Fuzzy Logic Controller (FLC), neuro fuzzy controller and conventional Proportional-Integral-Derivative (PID) controller as benchmark to the performance of fuzzy system. The most commonly used controller for the speed control of DC motor is the conventional PID controller. Fuzzy logic controller and neuro-fuzzy contro...
INTRODUCTION “In the beginning God created the heavens and the earth. Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. And God said, let there be light, and there was light. God saw that the light was good, and he separated the light from the darkness. God called the light day, and the darkness he called night. And there was evening, and there was morning – the first day” [1]. Electricity, of which Ligh...
Abstract The computer program for machinery cost estimation (CP-Mace) is a Windows based software program that can be run on a Windows XP or higher system on computers. It is a user-friendly interactive program written in VISUAL BASIC 6 programming language for machinery management. It allows the user to interact with it by entering the required inputs and it will carry out the interactive calculations. The program enables the user to print out the output which is displayed on the screen. Th...
ABSTRACT Qualitative and quantitative predictions of reservoir properties and geometries beyond well control are vital to understanding the intrinsic characteristics of subsurface formations. Using well log data, 3D Seismic data, Geostatistical simulations, reservoir characterization, modeling via multivariate analysis was carried out for and lateral predictions on data set obtained from Liaohe field, western sag, Bohai Bay, Northern China. This sag is an intra-cratonic basin of Archean to Re...
