    This paper presents the findings of a case study with building simulation using EnergyPlus dynamic thermal simulation software, in which wall insulation was varied together with cooling set-point temperature in a hot and ...
  • Inambao, F.L.; Mosweu, M. (University of Botswana, 2001)
    Diesel engines are used in heavy duty applications because of their high effeciency an reliability. However, oxides of nitrogen emissions remain a major concern. In diesel engines, fuel combustion is responsible for a major ...
  • Uziak, J.; Loukanov, I. A. (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 ...
  • Mothibi, J.; Kutua, S. (University of Botswana, www.ub.bw, 2001)
    One of the critical elements that determine the competitiveness of nations is the population density of, and quality of its engineers. This view has been corroborated by researchers such as Biluch (1989), Garelli et al ...

  • Kiravu, C.S.A.M. (University of Botswana, 2000)
    Computer models are used to replicate the essential performance features of a physical element using convenient modeling and simulation programs. Within SPICE, an acronym for the Simulation Program with Integrated-Circuit ...
  • Matshediso, I.B. (University of Botswana, http://www.ub.bw, 2004)
    Although most SADC countries have or were in the process of liberalizing their legislation and fiscal regimes some member states seemed to levy exorbitant tax rates. SADC members’ states need to note that in designing the ...
  • Ketlogetswe, C.; Fiszdon, J.K.; Seabe, O.O. (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 ...
  • Ketlogetswe, C.; Mothudi, T.H. (Elsevier Science Ltd. http://www.elsevier.com/locate/rser, 2009)
    Lack of access to electricity grid form the main challenge facing majority of developing regions particularly in rural communities. The situation is driven mostly by the absence of electricity infrastructure in most of ...
  • Oladiran, M.T.; Pheko, H. (Elsevier Science Ltd, http://journals.elsevier.com/00014575/accident-analysis-and-prevention/, 1995)
    In many African countries, including Botswana, the driving schools and instruction given to pupils are uncontrolled. Thus, this paper presents the results of an investigation into the level of professional training offered ...
  • Kanyarusoke, K.E.; Uziak, J. (Wiley Periodicals Inc. http://onlinelibrary.wiley.com/journal/10.1002/(ISSN)1099-0542, 2009)
    Formal Engineering Education has traditionally been delivered using the low technology—high touch lecturing method, in which the lecturer and student meet face to face. Distance education in this field has been quite ...
  • Loukanov, I. A.; Uziak, J. (International Symposium on Theory of Machines and Mechanisms (IFToMM), 2001)
    The single-stroke ram press machine is widely used for sunflower oil extraction in African countries. It is manually operated, low speed machine constructed on the basis of slider-crank mechanism. The paper presents a ...
