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...

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...
ABSTRACT This research work presents the design concept, construction and testing of portable crucible furnace which uses diesel oil as fuel. The diesel fired crucible furnace was designed, constructed using locally available engineering materials mild steel sheet of 1.5 mm, the materials used in this work were obtained from the local markets within Akure and Lagos. They include: mild steel sheet of 1.5mm thickness, compressor pot, stainless steel pipe of 60mm diameter, refractory material (...
ABSTRACT The design and construction of a 50HZ, 240V 1 kV A inverter is primarily based on an inverter circuit which inverts the D.C. source voltage from a battery, AC voltage for AC powered appliances. The overall operation of this system comprises inter connections of many subcircuits to give optimum performances. The sub circuit include; the oscillator circuit, PWM circuit, driver circuit, low battery/overload shutdown circuit, charging control/soft charging circuit, surge protection circ...
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
