The study concentrated on the 220 kV double circuit’s Wawa- Wadi halfa Transmission Line Project, the three types of the transmission towers has different configurations and same...
Abstract Designing and controlling a robotic arm with great performance is one of the fields of interest in many applications. This thesis is concerned with the problems control of robot arm (mentor) using Proportional Integral Derivative (PID) controller for axis1 (shoulder) and axis2 (elbow). The research work was undertaken in the following developmental stages; first stage, estimation of the transfer functions of Direct current (DC) motors actuators of tow axis’s using system identific...
Abstract Fuzzy logic is a paradigm for an alternative design methodology, which can be applied in developing both linear and non-linear systems for embedded control. One of successful application that can use fuzzy control is liquid level control. This control system keeps developing from time to time to replace the ordinary system which applies mechanical functions in its control in order to improve the system reliability. In order to find the best design to stabilize the liquid level, the ...
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 Robots are used for the most boring and repetitive jobs in manufacturing. The military and police use robots for dangerous jobs, such as manipulating explosive devices. In this project of simulation of industrial robotic arm to pick and place like in cement factory at rotary packing machine, The conventional packing system is working manually by hand which need more labors to accomplish the packing process and also require a great effort from these labors which will lead to incr...

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 Software-defined network continues to be one of the most hyped technology evolutions in information and communication technology compare to all traditional and perfuse network technologies. These traditional networks introduce many challengestime-consuming, Multi-vendor environments require a high level of expertise and complicate network segmentation, inconvenience and difficulty of learning to manage such a huge systems and devices and more. In this study, mininet software is ...
Abstract This study was conducted to test the possibility of benefiting from the blast furnaces slag resulting from the production of steel at Giad Factory south of the city of Khartoum –Sudan. The study aimed to determine the effect of partially replacing some of the concrete mix components with steel slag to study the effect on the compressive strength and workability of the concrete mixture. A mix design was prepared for standard according to the British and US by using another mixes whe...
ABSTRACT Visual Servoing has been a focus of intensive research form the last three decades due to its various robotic applications, mainly to allow performing autonomous tasks with the help of image sensors. This thesis presenting a visual servoing control system for a 3DOF robotic arm which is visual approach of servo using a vision sensor as a feedback, this approach introduce a better flexibility more than usual used passive sensors allow the robot arm to track the object without dependi...
ABSTRACT This project presents a system which is a power based auto select technology which automatically selects an active phase from a three phase supply, for single phase load. This eliminate the use or' conventional manual changeover using rewireable fuses. This design was implemented using a combination of Op-Amps 555 timer and relay (switch) circuit to achieve the set aim. Testing results showed that the load will continue to receive power even when failure occurs in any of the three ...
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 design of switched local area networks in practice has largely been based on heuristics and experience; in fact, in many situations, no network design is carried out, but only network installation (network cabling and nodes/equipment placements). This has resulted in local area networks that are sluggish, and that fail to satisfy the users that are connected to such networks in terms of speed of uploading and downloading of information, when, a user’s computer is in a communic...
ABSTRACT Ability to use electrical energy when required is one of the fundamental presumptions of a modern society, and the introduction of complex and sensitive machines and systems into the network had increased the need for high reliability of supply [1]. Deregulation and competition are forcing improvements in efficiency and reductions in cost while customers are becoming more sensitive to electrical disturbances and are demanding higher levels of service reliability. Since a typical dist...
ABSTRACT African Locust Bean (Parkia biglobosa) seeds known as ‘Iyere’ in Yoruba language were fermented aerobically and anaerobically at 40, 50, 60 and 70 °С for five days (120 hours) with the aid of two starter cultures - Bacillus Subtilis and Saccharomyces Cerevisiae to a vegetable protein based food condiment known as ‘Iru’. The Fermenter was fabricated with galvanized iron, thus getting rid of the unhygienic methods of producing it locally. Samples were taken every day (24 hour...
