ABSTRACT Waste management is a very big challenge in Nigeria today.
ABSTRACT Most Finite Element Analysts in Nigeria develop own codes for their analysis due to inability to purchase commercial finite element analysis software packages that GUI geometric modelers and difficulty in managing coordinate data from imported CAD files.
ABSTRACT The fact that the drive parameters space of harmonically excited pendulum consist of mix parameters combination leading to different dynamics phenomena including chaotic and periodic responses is a strong motivation for this study aim at estimating the peak frequency that favour chaotic response
ABSTRACT Sustainability of agriculture is dependent upon availability of reliable climatic data for planning. Daily and monthly data were obtained for Ibadan, Nigeria from International Institute of Tropical Agriculture (niA) automatic weather station and Nigerian Meteorological Agency (NMA) manual weather station.
Abstract The contribution of this paper to traffic engineering is the application of Laplace Transform to the quantification of speed control in the modelling of road bumps with hollow rectangular shape. The paper simulates the behaviour of a vehicle when passing over a series of bumps. In many countries the current practice used for lowering the vehicle speed is to raise road bumps above the road surface. If a hollow bump is used it may be economical and offers other advantages over road bu...
ABSTRACT An electricity audit of a building is the process whereby an energy manager survey and analyzes how energy is used in the building with the main objective of identifying opportunities for reducing the amount of energy used and ensuring that available energy is used efficiently.
ABSTRACT A gravitational drip Irrigation system was designed and constructed using available materials; and tested for the use of small scale farmers.
ABSTRACT Two field experiments were conducted to compare the growth and yield of tomatoes using experimentation and FAO AquaCrop model at the University of Cape Coast Teaching and Research Farm in the Cape Coast Metropolitan Assembly of the Central Region of Ghana. The Randomized Complete Block Design was used with four (4) treatments and four(4) replications for the two experiments. The treatments used for both experiments were T1 – Full irrigation (100 %), T2 – 90 % irrigation, T3 – 8...
INTRODUCTION In the recent times, the application of interactive software algorithms have made tremendous impact in the field of technology and engineering, various computer-aided methods are now used in virtually dl its aspects of human endeavour. This work is on the development of a software algorithm to model and forecast energy Loads with a possible choice of three different forecasting models. The developed software does not only remove the medium associated with Energy modeling and fore...
abstract Modelling and prediction of wind speed are essential prerequisites in the sitting and sizing of wind power applications. The profile of wind speed in Nigeria is modelled using artificial neural network (ANN). The ANN model consists of 3-layered, feed-forward, back-propagation network with different configurations, designed using the Neural Toolbox for MATLAB. The monthly mean daily wind speed data monitored at 10 m above ground level for a period of 20 years (1983–2003) for 28 grou...
ABSTRACT Earth dam failures could result in the loss of lives, damage to properties, health, environmental and social problems. Distressed dams cost a lot of resources and inconveniences to remediate. There is paucity of data on failures and distresses of many earth dams located in the north-eastern part of Nigeria. This study was designed to determine the geological, hydrometeorological, engineering factors and soil properties responsible for the failures and distresses of earth dams. A tota...
ABSTRACT Boundaries of six selected countries one from each continent were studied, using fractal dimension technique. The Area – Perimeter relation method was used, where land area covered and boundary length of designated countries were measured in the unit of known box size (Box counting). The loglog plots of these variables were obtained and the slopes were measured as the required dimensions. Fractal dimensions determined lie between 1.19 and 1.55. The scale size of the maps, and the n...
ABSTRACT Engineering research is a sine-qua-non for development of new products, new production processes, hence production lines in the quest for self reliance in any economy. Modeling and simulation is a veritable tool for such research and development. This paper presents the multifaceted use of modeling and simulation as decision tools for engineering facet of an economy drawing examples from two different engineering disciplines- Metallurgical and Civil.
ABSTRACT In this study, the short-term load pattern for the University of Ibadan was investigated and a multilayered feed-forward artificial neural networks (ANN) model was developed to forecast the time series half-hourly load pattern of the system using the load data for a period of 5 years (2000 to 2004). The study showed that the mean half hourly load for the period of study ranged between 1.3 and 2.2 MW, and the coefficient of determination (R2 -values) of the ANN predicted and the measu...
ABSTRACT Commercial act~vated carbons are produced from bituminous and lignite coal. The environmental impacts and potentially increasing cost of coal has encouraged the search for other alternatives in agricultural wastes. The objectives of this study were to develop process flow diagrams for the large scale production of activated carbon from three agricultural wastes namely: coconut shells, oil-palm shells, and sugarcane bagasse as well as carrying out an economic evaluation to estimate th...
