Modelling and simulation of an air motor system using extended radial basis algorithm
(University of Botswana, Faculty of Engineering and Technology, http://ajol.info/index.php/bjt, 2007-04)
This article proposes a new modeling scheme using extended radial basis function (RBF) and adaptive neuro-fuzzy filter for handling nonlinear uncertainties of an air motor servo valve. This model combines the fast model ...
Solar chimney power generation project - The case for Botswana
(Elsevier Science Ltd. www.elsevier.com/locate/rser, 2007)
Import of a huge proportion of electrical energy from the Southern African Power Pool, and the
geographical location and population distribution of Botswana stimulated the need to consider
renewable energy as an alternative ...
Application of enamel-coating for draught reduction of a mouldboard plough
(Akademiai Kiado, 2007)
The effect of enamel-coating on the draught performance of an animal-drawn
mouldboard plough was studied. A single furrow swing mouldboard plough-Maun
Series, and the same type enamel-coated plough both ox-drawn, are ...
Energy and exergy analyses of energy consumptions in the industrial sector in South Africa
(Elsevier Science Ltd, http://www.elsevier.com/locate/apenergy, 2007)
The energy-utilization over a 10-year period (1994–2003) has been analysed for the South African
industrial sector, which consumes more primary energy than any other sector of the economy. Four
principal sub-sectors, ...

Performance evaluation of commonly used oil ram press machines
(CIGR Journal http://www.cigrjournal.org/, 2007)
The ram-press technology for oil expression has received a lot of attention in many African countries during the last two decades. The technology is based on manually operated mechanical
presses, which employ a slider-crank ...
Investigating the pumping process of a resonance-vibrating pump for medium-depth boreholes
(Research in Agricultural Engineering http://journals.uzpi.cz/web/RAE.htm, 2007)
This paper deals with the pumping process of a resonance-vibrating pump, which utilizes the resonance vibrations
of one degree-of-freedom oscillating system. The pump is powered by a mechanical shaker consisting of ...
