ABSTRACT A switch is an imperative constituent of any electronic or electrical circuit. It can either be mechanical, electro-mechanical or electronic. Mechanical and electro mechanical switches are prone to wear and tear with time. The introduction of semiconductors has led to the invention of electronic switches that are more efficient, fast and durable. Further development of electronic switches led to the production of touch-sensitive switches. This project is based on the design and const...
ABSTRACT Electricity companies typically possess numerous units and they need to commit unit because electricity cannot be stored in a large-scale system and demand is a random variable process fluctuating with the time of the day and the day of the week. A problem that must be frequently resolved by electricity utility is to economically determine a schedule of what units will be used to meet the forecasted demand, and satisfy operating constraints. Lagrangian multiplier method is one of the...
ABSTRACT Electronic Digital message display Board is an electronic gadget that is capable of displaying length of alphanumeric characters, symbols and any form of representation on a matrix of light emitting diodes (LED) scrolling the characters across the screen for information disemination. This project set out to solve the problem of inadequate clarity, objectiveness and degree of comprehension inherent in paper bill boards. Also, response to the information is further enhanced when th...
ABSTRACT This project “maintenance of urban infrastructures (a case study of Ilorin metropolis)” lays emphasis on the various Infrastructures such as Roads, Rail, Electricity, Water-Supply, Solid Waste Management Facilities, Drainage Facilities and Sewerage. The various magnitude and the facilities provided were looked upon; the various defects and possible remedies to some specific infrastructures were also looked at. The major data collection procedures were from the various infrastruct...
ABSTRACT This research work show cases the potentials of Itakpe Iron concentrate for Magneto-rhelogical abilities. The concentrate was first ball milled to size reduce it then subjected to low magnetic strength from magnetic bits in-situ the magnetic fluid. It was determined that temperature affected the fluid inversely, as temperature increased at the shear rates from the viscometer and Newtonian viscosity calculated reduced, giving a negative relationship between temperature and Newtonian v...
ABSTRACT Urban population is rapidly increasing in Ilorin along with attendant increased water demand. The inadequacies of water supply services has forced the populace to depend on dug wells, boreholes, water tankers, street vendors etc. for their water needs. People spend hour’s daily carrying jerry can all around to collect and queue for water at the public water tap with high opportunity cost of time and intense economic wastage. This study assess the sustainability�...
A technical report on student work experience scheme on laptop repair. The students industrial work experience scheme (SIWES) established in 1973 by decree 23 of Federal Republic of Nigeria is the accepted skills training programme involving the students,universities and the industry (employers of labor), that is a part of the approved minimum academic standards in various degree programme for all the Nigerian Universities. I worked in the Engineering and Standards Department of the D...
ABSTRACT During this research work, namely; the undrained shear behavior of soils within Nnamdi Azikiwe University, five different samples within the university compound were analyzed. Some laboratory test was carried out for classification and identification of their engineering properties, these tests include particle size distribution, Atterberg limit test, specific gravity, and free swell tests. Also, shear strength test (UU triaxial test) at different cell pressures and one-dimensional c...
Abstract This research work focuses on development of practical instructional guide in the production of portable Universal SerialBus (UBS) Charger. Two research questions were set to guide the study. The study was carried out in Federal College of Education(Technical) Omoku Rivers State. The study adopted research and development design. The population for this study is 337 NCE I, II,and III electrical / electronics technology students. The sample of the study consists of 103 NCE I, II, and ...
ABSTRACT This project work has covered the design of an automatic security lighting system for ATBU, Yelwa Campus. Requirements for illuminance, type of fittings, power dissipation and mounting height were put into consideration. An electronic model of the campus was built with the streets outlined and lamps fixed at positions along the streets according to the design. An electronic control, based on a Light Dependent Resistor (LDR) is built, which provides automatic switch on and switch off ...
ABSTRACT No one form of power can sustain a nation. The ever increasing demand for electrical power has arisen from our lifestyles with revolves around electric power to speed up processes of development such as manufacturing, service provision and general well being of man. The need for the provision of quick but minute energy to prevent the disruption of small but very important business or personal processes could be life saving promoting efficiency at all times. This project work goes thr...
Adding to the requirement and need for power supply for day to day activities, it is therefore a necessity to design the power system to maintain minimal technical losses in the network, because most of our system component lack sufficient reactive power ability, this mean that the penetration of distributed generation (DG) will give way to reduce the transmission and distribution system resources thereby increase the reliability and probably better the power quality at all time. Hence the ob...
ABSTRACT Physical and aerodynamic properties of African breadfruit (Treculia africana) seeds were studied at four moisture levels: 12.50, 15.00, 17.50 and 20.10% wet basis (w.b). As moisture content increased from 10.50 to 20.10% wet basis (w.b), the average weight, major diameter, minor diameter, intermediate diameter, geometric mean diameter, arithmetic mean diameter of the seeds ranged from 0.35-0.60g, 8.0-10.06mm, 4.04-5.00mm, 2.96-4.60mm, 4.52-6.03mm, and 5.03-6.55mm respectively. Also t...
Abstract In this project we designed a solar powered computer control system for electrical machines and spark ignition engines. It is made up of a hardware device that comprises of various electrical components which are powered by a 25W solar panel. The power cord of the machines are modified and connected to the hardware and the hardware is in turn connected to a laptop computer using a USB cord. The machines are controlled from the laptop computer using special software deve...
ABSTRACT The modern manufacturing environment is dynamic and uncertain. In line with the global trend in manufacturing, this project is carried out to explore into the potentials of robots in manufacturing, service industry, and domestic use. The robot was designed and constructed to incorporate the use of mobile phones as control mechanism via dual-tonemultiple frequency (DTMF). Various components such as the Gripper, Gears, Chains, and Control system were designed with good factor of saf...
