  • Kok, S; Botha, N; Inglis, M (John Wiley & Sons, 2014-08)
    Goldmann applanation tonometry (GAT) is a method used to estimate the intraocular pressure by measuring the indentation resistance of the cornea. A popular approach to investigate the sensitivity of GAT results to material ...
  • Roberts, David P (Southern African Institute of Mining and Metallurgy (SAIMM), 2017-07)
    Bore-and-fill mining was implemented at a pilot site in Tau Tona mine’s shaft pillar on 97 level. Observations, scan data and measurements from this site were used to calibrate an inelastic numerical model of bore-and-fill ...
  • Eddy, C; de Saxe, Christopher C; Cebon, D (Camera-based measurement of cyclist motion, 2018-08)
    Heavy Goods Vehicles (HGVs) are overrepresented in cyclist fatality statistics in the UK relative to their proportion of total traffic volume. In particular, the statistics highlight a problem for vehicles turning left ...
  • Green, JJ; Bosscha, Peter A; Candy, L; Hlophe, K; Coetzee, S; Brink, S (2010-09)
    Safety in mines is of paramount importance, especially in the labour intensive operations of South Africa, where upward of 300 000 people are employed on a daily basis in an environment that is inherently dangerous. On ...
  • Mangera, R; Senekal, F; Nicolls, F (Avestia Publishing, 2014)
    Gesture recognition has many applications ranging from health care to entertainment. However for it to be a feasible method of human-computer interaction it is essential that only intentional movements are interpreted and ...
  • Coetzer, W; Moodley, D; Gerber, A (Semantics for Biodiversity, 2013-05)
    The domain complexity and structural- and semantic heterogeneity of biodiversity data, as well as idiosyncratic legacy data-creation processes, present significant integration and interoperability challenges. In this paper ...
  • Marivate, Vukosi N; Moiloa, P (IEEE, 2016-11)
    The increasing prevalence of Social Media platform use has brought with it an explosion of new user generated public data. This data is centered around many, diverse topics. One theme of interest is how one can tap into ...
  • Khan, Zubeida C (Academic Conferences and Publishing (ACPI)., 2019-03)
    Computer Security Incident Response Teams (CSIRTs) are responsible for data collection and analysis concerning cyber security threat incidents. In order to provide the best service support for cyber security breaches, ...
  • Ackermann, ER; Grobler, TL; Kleynhans, W; Olivier, JC; Salmon, BP; Van Zyl, AJ (Taylor & Francis, 2012-09)
    We use Cavalieri’s principle to develop a novel integration technique which we call Cavalieri integration. Cavalieri integrals differ from Riemann integrals in that non-rectangular integration strips are used. In this way ...
  • Tamsaout, T; Kheloufi, K; Amara, EH; Arthur, Nana KK; Pityana, Sisa L (Southern African Institute of Industrial Engineering, 2017-11)
    A theoretical approach based on a numerical simulation using experimental data is proposed as a contribution to the study of laser-based additive manufacturing by direct energy deposition (DED). The aim is to simulate the ...
  • Kekana, J; Siyakatshana, Njabulo; Wessels, G; Ubbink, O (2011-01)
    In this work the development of a numerical model capable of identifying suitable conditions responsible for spontaneous combustion of coal storage piles and carbonaceous waste dumps are presented. The developed model ...
  • Nkosi, MT; Mekuria, Fisseha; Gejibo, SH (IEEE, 2011-06)
    Healthcare providers are facing growing challenges in patient diagnostics and information gathering due to in-adequate infrastructure and insufficient number of health-care professionals to perform such operations. The ...
  • Mutanga, MB; Mudali, P; Dlamini, IZ; Ndlovu, L; Xulu, SS (The authors, 2010-05)
    Network forensics plays a major role in the investigation of criminal activities involving computer networks. Investigating such crimes is still an open research area due to the fact that technology is always advancing ...
  • Barnard, E (PRASA, 2009-11)
    The authors have previously argued that the infamous "No Free Lunch" theorem for supervised learning is a paradoxical result of a misleading choice of prior probabilities. Here, they provide more analysis of the dangers ...
  • Hwabamungu, B; Brown, I; Williams, Q (Association for Information Systems Special Interest Group for ICT in Global Development (SIG GlobDev), 2015-05)
    Information Systems (IS) strategizing research conducted mostly in the private sector setting indicates that there are many challenges to the implementation of Information Systems strategy and that there is need for further ...
  • Van Eden, B; Rosman, Benjamin S; Withey, Daniel J; Ratshidaho, T; Keaikitse, M; Masha, D; Kleinhans, A; Shaik, A (RobMech, 2014-11)
    Mobile manipulation is a robotics paradigm with the potential to make major contributions to a number of important domain areas. Although some mobile manipulators are commercially available, bespoke systems can be assembled ...
  • Mosola, NN; Dlamini, Thandokuhle M; Blackledge, JM; Eloff, JHP; Venter, HS (2017-09)
    Cloud computing brings flexible and cost effective services. However, security concerns plague the cloud. Data confidentiality is one of the concerns inhibiting the adoption of cloud computing. This concern stems from ...
  • Oboirien, BO; Engelbrecht, AD; North, Brian C; Du Cann, VM; Falcon, R (2009-03)
    There is currently a gap in the understanding of the morphological transformations experienced by high ash and intertinite-rich coals undergoing conversion to char during atmospheric gasification. In this study, work has ...
  • van Vuuren, DS (2011-01)
    This presentation looks at routes to produce titanium, its basic physical properties and main process routes. It concludes that basic physical properties of the relevant chemicals have major effects on the selection of the ...
  • Motlatle, Abesach M; Kesavan Pillai, Sreejarani; Scriba, Manfred R; Ray, Suprakas S (Springer, 2016-10)
    Cu nanoparticles were synthesized using low-temperature aqueous reduction method at pH 3, 5, 7, 9 and 11 in presence of ascorbic acid and polyvinylpyrrolidone. The nanoparticles were characterized using transmission electron ...
