Abstract: This study reports on the development in road traffic accidents in Nigeria since 1994.
The preliminary survey took Edo state, one of the 36 constituent States of Nigeria, as a case study.
An intervention model, which is a combination of an ARIMA noise and dichotomous models, was
employed in analyzing a seven-year monthly accident time series obtained from the Federal Office
of Statistics and the Federal Road Safety Corps of Nigeria. The Durbin Watson’s test statistic, used
to ascertain the adequacy of our ARIMA predictive model, suggested that the intervention model
adopted has a good fit. The study points up a significant reduction in the rate of road traffic
accidents through multiple policy interventions of Nigeria.
Abstract: To achieve meaningful and sustainable development of Africa, the continent must of
necessity look inwards particularly in the areas of Science, Engineering, technology capacity
building; and this is in view of the growing trends in globalization. There must be an active
collaboration and networking between research and industry on the one hand and between
researchers across the nations of Africa. This will promote technical cooperation which is sine qua
non to the development of the continent. A survey project on viable technological invention and
innovation in Engineering Research and Development (R&D) in Nigeria and their impact on
industry development by the Directorate of Technical Cooperation in Africa (DTCA) indicates that:
(a) though quite some achievements have been recorded in this sector, most of the inventions and
innovations are still at the level of incubation: (b) funding is a critical factor limiting development
of the Engineering Research and Development (R&D) sector: (c) there is minimum linkage and
collaboration among researchers, as well as between Research and industry, (d) the engineering
base remains small, fragmented and operating below the thresholds that would enable it make any
meaningful impact on industrial development: (e) brain drain is a key challenge as some of the best
and brightest engineers migrate to greener pastures mainly in the western countries. This paper
review the result of this project and argues for concerted efforts by all relevant stakeholders to
promotes full development and commercialization of viable inventions and innovations towards the
rapid development of Africa. The role of the DTCA in this is also highlighted.
Abstract: In this paper the author used his personal experience having passed through all the facets
of technological education specializing in Mechanical Engineering to solve the problem of noncontinuity
of technological educational system. Critical Path Method (CPM) was used to develop a
model for the continuity of Technological Education using Nigeria and Ghana as a case study. The
paper completely eliminates the terminal certificates awarded in some Nigerian and Ghanaian
Other educational lines like: Education, Art and Sciences were compared with that of Technological
line and solutions were proffered to the identified problems.
Abstract: In this study, the correlation between corrosion behaviour and formations, and topographic
characteristics of machined surfaces of stainless steel AISI 304 is investigated. Face turning was
performed for combinations of cutting conditions, leading to four differing surface patterns
owing to regular chip formation, very small chip thickness effect and built-up-edge formation.
To simulate industrial and environmental corrosion two corrosion tests were applied i.e. alternate
immersion method and exposure to FeCl3 solution. Different corrosion behaviour was revealed
through stereoscopic examination of the surfaces with regard to machining conditions and the
best global anti-corrosive performance was exhibited by the surfaces generated under regular
Abstract: This study employed Computational Fluid Dynamics, CFD solution to configure the
entire shape of the nozzle. The problems arising from the initial geometrical shape obtained using
one-dimensional approach were highlighted. Then with a two-dimensional approach and coded
FORTRAN programs, the convergent portion was handled with time matching CFD while the
divergent portion was handled with space matching CFD. A post-processing results analysis shows
that the results are in agreement with that obtained with the analytical approach. This research has
demonstrated significant and tangible benefits of the use of CFD numerical experimentation to
optimize the shape of the nozzle. These benefits are not solely limited to performance
enhancements, but solution reliability and algorithm development.
Abstract: This paper describes computer-aided-design software which accurately and efficiently
designs internal combustion engine (I.C.) parts with the aid of Microsoft Visual Basic Object -
oriented programming language. In addition to numerically outputting solutions (design
parameters), the software also provides graphical solutions which facilitates easy visualization of
trends in the variation of the solutions with important parameters. We then illustrate its accuracy
and efficiency with some benchmark examples.
Abstract: There are several reasons why industrial engineers need to optimize process layout
designs. This paper points out the justification and discusses the qualitative and quantitative
techniques involved in the determination of an optimal process layout for a pilot alkyd resin and
its end products manufacturing system. It also spotlights practical decisions required for
achieving optimality in the design process. It is the belief of the authors that with some
improvements on the final layout, our proposed layout will be a ballpark of eco-factory moored
on green manufacturing.
Abstract: The design of a fixed bed adsorption unit using adsorbent produced from locally available
palm kernel shell has been investigated using Microsoft Excel spreadsheet. Various mathematical
models were considered but the simpler and more convenient Wheeler-Robell model was adopted
in the design. The model was adopted in designing a template with Microsoft Excel Spreadsheet. A
Microsoft Excel Spreadsheet was developed for the design. The template was used to determine the
design parameters, such as length of column, diameter of bed, bed height and pressure drop across
