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
ABSTRACT This study reports synthesis of solidacid catalyst from cheaper raw materials for efficient biodiesel production. The dissertation consists of six main research section including: (1) Synthesis and characterization of ordered solidacid catalyst from kaolin; (2) Synthesis and characterization of hierarchical nanoporous HY zeolite from acid activated kaolin; (3) Synthesis of nanoporous HY zeolites from activated kaolin, a central composite design (CCD) optimization study; (4) Synthesis...
ABSTRACT This research project assesses the geotechnical characterization of soils used for the construction of the failed sections along Ikole- Oye Ekiti Road, Ekiti State, Nigeria. This road spans 23kms. The study area falls within coordinates 7. 7979306° N (Oye) - 7. 7982660 N (Ikole) and 5.3285505°E (Oye) - 5.5144930°E (Ikole). It is a known fact throughout the world that the conditions of any road largely depend upon its geotechnical properties such properties includes soil strength,...
ABSTRACT Water scarcity is a problem in many parts of the world. In some regions, there is physical water scarcity because there are not enough resources of water to meet the increasing demand, while other parts of the world have an economic scarcity, where resources are more abundant but poor governance and other problems render water unavailable for most of the population. Where the problem is economic water scarcity, there are many solutions that could ameliorate the problem, but most tim...
ABSTRACT Globally, natural disasters are becoming places lately, and they are the results of climate change due to natural forces. Some of these disasters like floods, earthquakes, landslides and draught happen, resulting in loss of human lives and properties. Flood occurs when two or more acres of dry land or two or more properties are inundated by water or mudflow. In this study, the reconnaissance survey of the study area was carried out. The topographical map of the area contributing run...
ABSTRACT The human eye is a vital organ of vision which gives the sense of sight. However, there are many diseases that affect the human eye and can lead to partial or total blindness. The major causes of blindness include cataract, glaucoma, diabetic retinopathy and several other corneal and retinal infections but most of them can be prevented with an early diagnosis. Therefore, there is the need for a cheaper, easy-to-understand and readily available system to aid the diagnostic proces...
ABSTRACT Zeolites are important chemical materials used in chemical processes. The manufacture of the materials usually involves the use of expensive chemicals. This study involves the use of Elefun Nigerian Kaolin (ENK) as precursor material for the development of zeolite Y. The synthesis of zeolite Y was successful following a sequence: collection of raw kaolin clay from Elefun area of Ogun state, Nigeria; subjecting it to, calcination, partial dealumination and final hydrothermal syn...
ABSTRACT Converting the huge amount of waste cooking oils presently generated globally to biodiesel as complementary energy source to fossil fuel is one of the major routes to sustainable energy management. However, producing quality biodiesel at established optimum conditions, through a clean technology with favourable environmental implications is of greater importance. This research focused on achieving the latter through alkali catalysed trans-esterification process of biodiesel producti...
ABSTRACT Recognition is an important task in many organisations ranging from law enforcement to education. Therefore, organisations are constantly in search of more efficient and error free ways to carry out the recognition process. Existing methods of recognition can be categorized as traditional or technology assisted. The aim of this project is to develop a recognition system that is based on authentication using one physiological trait of an individual. The proposed recognition system wa...
