ABSTRACT The development of a framework for the local production of low-cost injection moulds, using inputs and technical skills available within a typical Nigerian city is the focus of this study.
ABSTRACT Abundant and economical energy is the life blood of modern civilization.
ABSTRACT A biobjective model is proposed for production planning in a multi stage, multi facility production system.
Abstract This paper presents experimental and simulation study of the effects of stress on microstructure and failure morphology of low carbon steel under plane stress conditions. The study has revealed large extension of grains at the point of fracture and, stress and strain looped around the pearlitic faces of the microstructure matrix. The stress and strain distributions in the microstructure have shown that concentration of stress and strain on the pearlite were instrumental to oblique f...
ABSTRACT Chainsaw milling is an inevitable means of preventing quantum wastage of valuable and scarce wood resource in un accesible locations.
ABSTRACT This paper presents a case study in the development and application of a time study model in a rice milling firm.
ABSTRACT Development and enhancement of innovative engineering curriculum is a vital exercise in producing well grounded graduates that can perform in todays world.
ABSTRACT The paper presents the design and local manufacture of a mechanized extruder for electrode coating.
ABSTRACT A multipurpose machine for sieving of Ogi (ground corn slurry) and other applicable grain slurry compromises the sieving container which receives water from an external water unit and the slurry Ogi to be sieved through a hopper.
ABSTRACT The observed poor quality of graduates of some Nigerian Universities in recent times has been partly traced to in adequacies of the National University Admission Examination System. In this study an Artificial Neural Network (ANN) model. for predicting the likely performance of a and date being considered for admission into the university was developed and tested.
ABSTRACT The job scheduling mathematical model was applied to small scale oil winning processing in this paper with a view to develop a framework for the proper scheduling of jobs (orders) in oil winning processing firm in Nigeria. The problem is addressed by supposing we have (n) customers to be served (where n is large); in what way should customers’ order be processed such that the firm’s profit is maximized while the customers are not unnecessarily delayed? The paper addressed the pro...
ABSTRACT Sawdust particles soon after emission from the cutting machine usually move dynamically with transformation in some dimensions. This paper models the sawdust particle motion as a two dimensional transformation system of continuous time series. Cost could be saved using this approach instead of utilizing dynamic systems that depend on time history. TWP dimensional graphical representation of continuous time series of Duffing's dynamic system for sawdust particles was investigated with...
ABSTRACT Heat flow patterns in two salt bath furnaces were studied in this work using finite element(FE) analysis. The implications of the heat flows on long term stability of furnace performance were evaluated. One design had a purely silica brick back-up after the embedded heating element with asbestos and glass-wool fiber insulation just before the outer steel shell. The other had an additional air-gap insulation formed by cylindrical steel belts with spacers placed after the silica back-...
ABSTRACT Monitoring of surface roughness is an essential component in planning of machining processes as it affects the surface quality and dimensional accuracy of machined components. In this study, the development and application of a machine vision system suitable for on-line measurement of surface roughness of machined components using artificial neural network (ANN) is described. The system, which was based on digital image processing of the machined surface, consisted of a CCD camera, ...
ABSTRACT Fuel flexibility and capacity to burn broad spectrum of fuels at high combustion efficiency with minimum emissions of greenhouse gases are few of several key advantages fluidized bed combustion technology has over other existing combustion technology. This report examines the design, development and testing of an experimental model Bubbling fluidized bed combustor (BFBC). The developed BFBC has unique inert bed's temperature regulating system which implies that the use of external s...
