  • Van Zyl, Lourens H; Gledhill, Irvy MA (2011-11)
    A grid was generated with the base of the fin, i.e. the hinge line, on the axis of a cylindrical domain with a diameter of 2m. Due to the axial symmetry of the setup, rotation of the T-tail should not change the pressure ...
  • Moller, H; Govender, G; Stumpf, W (Trans Tech Publications, 2009-04)
    The T5 heat treatment of semi-solid metal (SSM) processed alloy F357 was investigated by considering the effects of cooling rate and natural aging after casting, as well as artificial aging parameters on tensile properties. ...
  • Moller, H; Govender, G; Stumpf, WE (Bentham Science Publishers, 2008)
    Semi-solid metal (SSM) processing is a unique manufacturing method to produce near-net shape products for various industrial applications. The aim is to obtain a semi-solid structure free of dendrites (which are formed by ...
  • Smith, Andrew C; Springhorn, H; Mulligan, SB; Weber, I; Norris, J (2011-05)
    We describe a new programming language that is based on physical elements and especially developed to test the hypothesis that a physical computer programming language is possible. This imperative language is deliberately ...
  • De Saxe, C; Kienhofer, F; Nordengen, Paul A (2012-09)
    The practice of issuing of abnormal load permits to South African car-carriers (allowing a 300 mm increase in height and 500 mm increase in length) is being phased out. Such allowances will only be granted if a car-carrier ...
  • Chen, H; Ojijo, Vincent O; Cele, H; Joubert, T; Ray, SS; Land, K (SPIE Proceedings, 2014-03)
    SU-8/Clay nanocomposite is considered as a candidate material for microcantilever sensor fabrication. Organically modified montmorillonite clay nanoparticles are dispersed in the universally used negative photoresist polymer ...
  • Dlodlo, N; Tolmay, JP (Elsevier, 2011)
    This paper describes an architecture that was designed to enable access to the scenarios/challenges on the SINGA platform. SINGA is a virtual platform that enables children facing barriers of access to information, services ...
  • Labuschagne, Philip W; Moolman, FS (2011-11)
    This presentation compiles a summary of current technologies to improve oxygen barrier properties of plastics.
  • Du Plessis, C (2002-09)
    Doing business in developing countries requires a thorough understanding not only of the challenges, but also of the differences of opinion that shapes people’s attitudes and choices. Working in developing countries certainly ...
  • Smith, Adrew C (2006-11)
    This paper describes early results in the development of an alternative programming method which uses large, three-dimensional acrylic blocks to construct programming sequences. Computer illiterate children can create a ...
  • Smith, Adrew C (INTECH, 2010-04)
    Various modes of tangible interfaces have been explored and researched. In this paper we limit our look at tangible user interfaces to a subset of these. The subset is characterised by portability and no attached tethers, ...
  • Roux, S (Popular Mechanics, 2011-07)
    At the CSIR’s National Laser Centre, a team of researchers is pursuing Free Space Quantum Communication: transmitting optical signals by using the quantum properties of laser light. The aim is to provide secure and safe ...
  • Buck, R; Pfahl, A; Roos, TH (2012-05)
    The layout for a solar tower test facility for CSIR, Pretoria, is described. The solar tower system is designed for 400kWth receiver outlet power. The heliostat field layout takes into account both the real (non-flat) ...
  • Kriel, M; Le Roux, H (CRC Press, 2012-08)
    This chapter briefly outlines a few mathematical techniques to track targets in 3D using a 2D radar. 2D radars are relatively cheap and efficient sensors that often form the first line of defence in airspace control. In ...
  • Aderibigbe, BA; Owonubi, SJ; Jayaramudu, J; Sadiku, ER; Ray, SS (Springer, 2015-10)
    Hydrogel biocomposites containing a combination of partially and thermally reduced graphene oxide (rGO) and natural polymer were prepared by free radical polymerization. The effect of rGO and the natural polymer on the ...
  • Maphanga, Charles P; Ombinda-Lemboumba, Saturnin; Manoto, Sello L; Maaza, Malik; Mthunzi-Kufa, Patience (SPIE, 2017-01)
    Human immunodeficiency virus (HIV-1) infection still remains one amongst the world’s most challenging infections since its discovery. Antiretroviral therapy is the recommended treatment of choice for HIV-1 infection taken ...

    South Africa currently has the highest incidence of TB per 100000 (358 per 100000) people in the world. In 2007 alone 112000 people died of TB in South Africa, of which 94 000 (72%) were co-infected with HIV. Although TB ...
  • Van Greunen, DG; Cordier, W; Nell, M; Van der Westhuyzen, Christiaan W; Steenkamp, V; Panayides, Jenny-Lee; Riley, DL (Elsevier, 2017-02)
    A series of twenty seven acetylcholinesterase inhibitors, as potential agents for the treatment of Alzheimer's disease, were designed and synthesised based upon previously unexplored chemical space surrounding the molecular ...
  • Olaitan, O; Herselman, Marlien; Wayi, N (2016-09)
    Due to the increased use of technology by a wider section of society, stakeholders, non-stakeholders and other informal interests can easily access an organisation’s most sacred information assets. As a result of the role ...
  • Halland, K; Britz, K; Klarman, S (2014-07)
