ABSTRACT Information and Communication Technology (ICT) is beginning to be recognised as one of the major instructional components especially in science subjects. This study sought to investigate the status of ICT in the teaching and learning of physics in secondary schools. It investigated: perception of teachers and students towards the use of ICT; physics teachers’ ICT competence; access to computers by both teachers and learners; teaching experience; and management’s and technical sup...
ABSTRACT There has been a steady increase in demand for clean and renewable energy globally. As a result, more effort has been put into research to harness solar energy from the sun to generate electricity using solar cells. Solar cells convert solar energy directly into electricity. Recent research findings indicate that properties of thin film solar cells strongly depend on the various deposition techniques chemical bath deposition (CBD) being one of them. This technique yields stable, adhe...
ABSTRACT Studying the process of groundwater flow in subsurface systems using numerical simulation has been widely practiced. The purpose of this study was to establish a 2D groundwater flow model for evaluating groundwater resources of the Voltaian Basin (around Tamale) in the Northern Region of Ghana. To understand the rate of abstraction of groundwater in the study area, a finite-element, steady-state groundwater flow model was used to simulate groundwater flow in the aquifer. COMSOL Mult...
ABSTRACT Class imbalance problem is prevalent in many real-world domains and as such has become an area of increasing interest for many researchers. In binary classification problems, imbalance learning refers to learning from a dataset with a high degree of skewness to the negative class. This phenomenon causes traditional classification algorithms to perform woefully when predicting positive classes with new examples. Data resampling is among the most commonly used techniques used to deal ...
ABSTRACT Degree of compaction (R %) value is an indicator in strength of earthwork construction. In the design of irrigation earthwork construction, degree of compaction value of compaction characteristics is often used, but laboratory test is time consuming and laborious. Fine aggregate classification and compaction characteristics are routinely determined for in-situ and borrow area (reservation area) soils used in the irrigation earthwork constructions. Developing regression based model to...
ABSTRACT There has been a growing concern in the development of alternative building materials to ensure housing for low-income earners who cannot afford owning houses due to high cost of modern materials. Plantain (Musa paradisiaca) peels are the major byproduct of plantain fruits, constituting about 40% of the fruits but are presently underutilized. This work covers the investigation into the effect of Ripe Plantain peel ash (RPPA) and Unripe Plantain peel ash (UPPA) as admixtures to concr...
ABSTRACT A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that each serve a particular purpose and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the ten-ain where the bridge is constructed and anchored, the material used to make it, and the funds available t...
ABSTRACT The importance of concrete in modem society cannot be underestimated. There is no escaping from the impact of concrete on everyday life. Concrete is a composite material which is made of filler and a binder. Typical concrete is a mixture of fine aggregate (sand), coarse aggregate (rock), cement, and water. Nowadays the usage of concrete is increasing from time to time due to the rapid development of construction industry. The usage of concrete is not only in building construction bu...
ABSTRACT This study investigates the influence of two main geotechnical properties of soils in the town of Ikole-Ekiti on civil engineering construction. The strength and compaction characteristics of the natural soil were determined. The investigation was carried out through laboratory tests on disturbed and undisturbed soil samples obtained from four trial pits (Samples A, B, C & D) in the town, across Ilotin, Ijemo-Titun, Yeye-Oba and Asin respectively. The samples were collected between ...
ABSTRACT Disinfection of water is a crucial step in the treatment of water in order to obtain clean drinking water. The use of water disinfection as a public health measure reduces the spread of diseases. This research paper examines water quality assessment of ground and surface water samples obtained from lkole campus of the Federal University Oye-Ekiti (FUOYE). The obtained stream water was tagged Sample A, and the ground water (borehole) was tagged Sample B. These two constitute major so...
ABSTRACT This project is designed to determine households' access to domestic water supply via mechanical and non-mechanical energy system in Usin, Ikole local government area Ekiti State Nigeria, in terms of quality and quantity as the importance of adequate safe water supply to human health cannot be over emphasized. However, safe/improve water supply to most Nigerian cities is still inadequate. In the study area the relationship between water quality the degree of water source protecti...
ABSTRACT Assessing the geotechnical parameters helps in improving the soil settlement which usually causes damage to the civil structure. Compaction is one of the most important and routine engineering techniques, performed to assure the safety and stability of soils. In this study, geotechnical investigations at the lkole campus of Federal University Oye-Ekiti, Ekiti State are carried out for undisturbed and ·disturbed samples obtained at five (5) specified locations and at a depths of t...
ABSTRACT Attendance is typically a list of people present at a particular event. Manual approach of attendance taking has not been very effective due to difficulty in keeping the attendance list over a long period of time, unnecessary time wastage during writing or signing, improper documentation, students forgetting to write or sign-the attendance paper among others. The aim of this project is to develop a technology assisted attendance system that will enhance efficient and effective means...
Abstract The aim of this project is to investigate and understand the load flow analysis for power systems, during abnormal condition using (Ne plane) with the main focus on load flow analysis theories and computer application. The thesis define the power system security and the effect of load flow , contingency analysis to power system security , and how it effect of equipment of power system network . The thesis investigate Sudan national electricity cooperation during big load period s , ...
Abstract This study is mainly concentrated on how to produce burnt clay bricks with a minimum firing cost and friendly Environmental Impact, through a new implemented energy – efficient technology, ie the Vertical Shaft Brick Kiln (VSBK) in the Sudan. The study aims to manufacture modeled building green bricks with different cheap solid additives having a high heating values [industrial and agricultural], petro-coke, animal dung, and saw-dust as an internal fuel.
