A fourier method of determining the speed fluctuation coefficient of a general slider-crank mechanism
(University of Botswana, 2001)
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 ...
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 ...
Assessment of ICT-based course delivery for mechanical engineering students: a case study
During the first semester of 2007/2008 academic session at the University of Botswana (UB), some mechanical engineering courses were delivered using a blended method i.e. online resource (eLearning) and traditional face to ...
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 ...
Measurement of operating forces in a ram press crushing sunflower seed
(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 ...
Spreadsheets: the ideal tool for distance learning in Engineering education
(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 ...
Acceptance of blackboard technology by mechanical engineering students at the University of Botswana
(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 ...
Introduction to general education courses to engineering programmes at the University of Botswana
(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 ...
Energy losses in a ram press machine for vegetable oil expression
(Dalhousie University, 2009)
Draught requirements of enamel coated animal drawn mouldboard plough
(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 ...
