Acceptance of blackboard technology by mechanical engineering students at the University of Botswana
Uziak, J. (Tempus Publications, 2009)Technology-based teaching and learning is entering academic life at an amazing rate. It comes whether invited or not. Students and lecturers are confronted with new technologies. There are new teaching methods to accompany ... -
Application of enamel-coating for draught reduction of a mouldboard plough
Loukanov, I.A.; Uziak, J. (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 ... -
Coupled buckling design of steel laced columns
Uziak, J.; Gizejowski, M. (University of Botswana, 2009)A new design developed by the authors that gives an opportunity to account for the interaction of different modes of buckling is presented.Eurocode 3 model is used as the reference model, an equivalent geometric imperfection ... -
Draught requirements of enamel coated animal drawn mouldboard plough
Loukanov, I. A.; Uziak, J.; Michalek, J. (Czech Academy of Agricultural Sciences http://agriculturejournals.cz/web/RAE.htm, 2005)The power requirement of tillage implements is an important design consideration particularly for animal-drawn implements where the power is limited. The paper presents the possibility of reduction in the draught requirements ... -

A fourier method of determining the speed fluctuation coefficient of a general slideer-crank mechanism
Uziak, J.; Foster, J.D.G. (University of Botswana, Faculty of Engineering and Technology, http://ajol.info/index.php/bjt, 2001-10)In this paper a method is presented which enables the solution of the equation of motion of the slider-crank mechanism. Expansion of functions into Fourier series is used in this method, whereby the solution of the equation ... -

Introduction to general education courses to engineering programmes at the University of Botswana
Uziak, J.; Oladiran, M. T. (Tempus Publications http://www.ijee.ie/, 2009)Complementary studies are fundamental for accreditation of engineering programmes in line with the Washington Accord. This paper presents the experiences of the University of Botswana in introducing General Education Courses ... -
Measurement of operating forces in a ram press crushing sunflower seed
Foster, J.D.G.; Uziak, J.; Loukanov, I.A. (Blackwell Publishing Ltd, http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1475-1305, 2009)This study presents the experimental setup and results of measurement of forces and moments in a manually operated ram press machine. Tests were conducted on a BP30 ram press using electrical resistance strain gauges to ... -
Performance evaluation of commonly used oil ram press machines
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 ... -
Spreadsheets: the ideal tool for distance learning in Engineering education
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 ... -
Theoritical analysis of an offset single-stroke ram press for sunflower oil extraction
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 ...
