ABSTRACT Electricity, of which Light is a product is the whole essence of life. This informed God's decision to command light into existence before the creation of all other things. Unfortunately, the undertakers of our electric power sector will not allow this beautiful idea of God to work in this country [2]. Electricity is not a primary source of energy; however, it is one of the most versatile forms [3]. It is known to play a significant role in the advancement of the standard of life of ...
ABSTRACT In this study, a nonlinear dynamic model for large scale fossil fueled boiler turbine power generation units is presented. The challenge in controller design for these plants exists because they are typically nonlinear and multi-variable with multiple control objectives. This thesis presents the application of a fuzzy logic based controller for boiler turbine plant to control the drum pressure, power output and water level. Fuzzy control system have been successfully applied to a wi...
ABSTRACT The Stone Age, The Gold Age, The Silver Age, The Bronze Age, The Iron Age, etc. Some of these periods in history lasted centuries but in recent times both the rate of major materials breakthroughs and their improvements are increasing ever faster. Materials are constituents of the earth and the earth is materials. In Genesis 2:1, it reads: “In the beginning, God created the heaven and the earth”. So the earth was either created simultaneously with the heaven or it was c...
ABSTRACT The proposed methods to solve optimal control problems are classified as direct methods and indirect methods. This thesis is based on solving optimal control problems using direct methods in which an optimal control problem is converted into a mathematical programming problem. The direct methods can be employed by using the parameterization technique which can be applied in three different ways: control parameterization, control-state parameterization and state parameterization. Her...
Abstract The objective of this research is focused on the vortex flow in Kaplan turbine runner - a tip vortex. CFD analysis was performed to predict the water flow inside the turbine for more diagnosing and investigation of the hydro power problem. On the basis of this analysis it is possible to estimate the existing and the intensity of vortex, danger of possible blade surface and runner chamber cavitations’ pitting and power losses. In the research, the ways how to predict vortex flow an...
ABSTRACT 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 expensive me...
ABSTRACT In this research the thermal reactors have been studied, we reviewed the history of thermal reactors focusing on comparing advantages and disadvantages of using of each thermal reactors class, accordingly to these classification. we choose the pressure water reactor as the best candidate of these thermal reactors, this is due to the isolations of the second vapor cycle from the pressure and vapor system in the first cycle. This enable the pressure water reactors to be the most stabl...
ABSTRACT An easy-to-use and accurate multi-frequency path loss model is a necessary tool for heterogeneous radio network planning and optimization towards achieving a smart campus. The learning ability in artificial intelligence may be exploited to reduce computational complexity and to improve prediction accuracy. In this research project, an optimal heterogeneous model was developed for path loss predictions in a typical university campus propagation environment using machine learning appr...
ABSTRACT This research presented a new method for the mass production of a high quality, low cost, sheet metal products using a die, press and transferring mechanism. The research presented a definition of the tool (die), its design parts and the types which differ as per the products and operations concerned. The researcher selected the progressive die used for mass production, for more elaborated studies because it combines a number of die design and function in one frame. Al Madinah Al Mu...
ABSTRACT Medical devices play an important role in human being health. Consequently, it is important that there should be unified inspection method for imported medical devices and unify a team of work consisting of all regulatory authorities in the country. A protocol for inspection of imported medical devices was prepared and explained in figure (flow chart) which was conducted by a questionnaire directed for interested people in charge of regulating and inspecting of imported medical devic...
Abstract CT scan and MRI machines are very essential for the advance diagnostic, more complicated and high cost equipment in the radiology department that its failure can cause a detrimental effect on its financial income and the ability to provide proper healthcare to the patient. This study was done in Khartoum state hospitals, centers, and a number of private hospitals which are about 15 hospitals and centers in the period from March 2016 to February 2017 .Empirical field , observation an...
ABSTRACT In the last decade, there was rapid growing of Wireless Sensor Networks (WSNs) for research and commercial uses. Low-cost/low-power WSNs techniques are utilised in various applications such as smart-home, industrial control, health care, agricultural fields, environmental purposes, biomedical systems, and scientific applications. The aim of this research is to find the suitable number of paths and hops in each path to be used in transmit power control protocols for multi-path unifor...
ABSTRACT The Automated Guided VehicleAGV or a programmable mobile vehicle is capable of transportation task fully automated at limited area such as using in industrial applications to transfer material and production around a manufacturing unit. In the traditional industry materials and products are transported and moved using workers which lead to waste of the time and increase labour cost. Also its unsafe for the workers themselves by exposing them to bone and muscle diseases and exposing ...
Abstract Wireless charging through inductive coupling could be one of the next technologies that carry the futures forward. In this study it has been shown that it is possible to charge low power devices wirelessly via inductive coupling. It minimizes the complexity that arises for the use of conventional wire system. In addition, the thesis also opens up new possibilities of wireless systems in other daily life uses. Much interest in the research has been conducted to determine the feasibili...
ABSTRACT The topic of today's lecture concerns Electricity as it exists in Nigeria from the very beginning. The lecture will take us through the developmental stages of Electricity infrastructure in Nigeria from the beginning to what it is now. We all know that the engine of life the world over, is the uninterrupted electrical power supply. We also know that there is a very strong link between the per capita consumption of electrical power and the state of physical advancement of a nat...
