ABSTRACT An assessment of farm transportation system to ascertain the availability of transportation for the evacuation of farm produce was undertaken in Osun and Oyo states of Nigeria employing printed questionnaires and personal communication as means of information collection. 20% of the farmers reside at between one and three km from their farms while for the remaining 80%, it ranges from four to 16 km. 17.6% of the farmers travel between one and three km to sell their produce while for t...
ABSTRACT The varying shapes and sizes of cassava tubers have made cassava peeling to one of the major problems in the mechanisation of cassava processing. A cassava peeling machine was designed and constructed. The design parameters include a power requirement of 0.36hp, belt tensions of 349.7 and 1807.5N and shaft diameter of 35mm. Its main component is a peeling chamber, which consists of two perforated drums rotating in the opposite direction. The machine had an average capacity of of 44.5...
Poor finishing and aesthetics capabilities of metal fabrication companies in Nigeria have been identified as a major cause of the poor acceptance of locally fabricated metal products. This study was aimed at assessing some finishing capabilities of Nigerian companies.
_ABSTRACT -. Nigeria has for long been a developing nation without much progress. An observation of some of the countries of the world reveals a strong interplay between the quality of engineering education and the technological advancement of such country.
ABSTRACT This paper presents an electronic Expert system platform to detect and diagnose existing and new cases of contagious diseases as they occur with minimal contact with the index patient(s) and healthcare personnel with a confidence level that can be used to initiate or suggest appropriate follow-up action(s). The aim is to use ICT tools for patient-diagnosis, raise a red flag in real-time and thus contain contagious cases which may degenerate into an epidemic by providing a way to ana...
Abstract: This paper presents the results of a mathematical model developed for predicting the 28-day compressive strength of foamed aerated concrete containing pulverised bone as partial replacement of cement for the purpose of quality controls. Strength-porosity relation was used as a basis for the development of the model, and the Bisection Methods of Numerical analysis was used to evaluate the inherent constants. For all the percentages of cement replacement with pulverised bone, the exp...
ABSTRACT Modeling of wind speed variation is an essential requirement in the estimation of the wind energy potential for a typical site. In this paper, the wind energy potential in Ibadan (Lat. 7.430 N; Long. 3.90 E; Alt. 227.2m) is statistically analyzed using daily wind speed data for 10 years (1995-2004) obtained from the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria. The daily, monthly, seasonal, and yearly wind speed probability density distributions are modeled...
ABSTRACT This study shows the usefulness of Artificial Neural Network (ANN) in maintenance planning and management.
ABSTRACT This work studied the effects of degrees of warm-split rolling at different temperatures on the strengths of three different grades of austenitic steels (chrome–manganese, chrome–manganese with Ni and Mo additions, chrome–nickel with Mn and Mo additions). The results were compared with cold-rolling effects on the steel grades. The tensile, hardness and impact strengths of the rolled products were obtained. The results showed that thermomechanical working remarkably influenced t...
ABSTRACT The analysis of a transient 2-Dimensional heat conduction problem by the Finite Element Method is hereby presented.
ABSTRACT Two layered rattan cement composite were made from Calamus Deeratus and Laccosperma Secundiflorum particles using cement:
ABSTRACT Leaf Area Index (LAI) is a concept that cuts across agricultural sciences and agricultural engineering with an encapsulating feature in environmental engineering. It is one of the most difficult 10 quantify properly owing to large spatial and temporal variability.
ABSTRACT This paper deals with facility maintenance scheduling model which incorporates opportunity and inflationary costs.
ABSTRACT This paper aims at applying a fuzzy logic control model to profitability in a case study of the plastic recycling industry in Nigeria. The studies of profitability components of the plastic recycling industry as used to develop a model framework and the application of fuzzy logic control model to the framework are given in this paper. A brief introduction to profitability concepts as well as useful suggestions and conclusions are all integral part of this paper which is based on the...
ABSTRACT This study presents a generalized analytical formulation of the Multi-Well Interference test problem using the concepts of the source and sinks functions as a tool for solving the basic interference equations.
