  • Ittmann, HW (Cape Media, 2008-05)
    Urbanisation, coupled with sustained economic growth, implies that more and more goods and commodities need to be supplied to urban areas. This trend has been observed world-wide in the last number of years. Whereas ...
  • Duvenhage, B (2015-11)
    Turbulent pockets of air in the atmosphere blur and disrupt the Point Spread Function (PSF) of a surveillance system. The PSF peak is offset in location, changed in size and in short exposures (or mild conditions) noticeably ...
  • Ismail, Y; Barnes, G; Mhlanga, T; Belyi, V; Forbes, A (2010-03)
    In this paper the authors outline an optical design for producing high-order Bessel-like beams with a z-dependent cone angle through the use of conventional optical elements, without the need for deliberate aberrations to ...
  • Nonyane, DR; Thokozani, M (Elsevier, 2012-05)
    Most of the methodologies published in literature on wastewater minimisation for batch processes are based on short term scheduling techniques. When these methods are applied to longer time horizons, the computational time ...
  • Macdonald, IAW; Crawford, RJM (National Scientific Programmes Unit: CSIR, 1988)
    This volume presents the proceedings of a conference held to review the state of knowledge on long-term data series from southern African ecosystems. Three chapters relate to marine environments: those of the West Coast ...
  • Ratsele, C; Dube, S; Lesoli, MS (GSSA, 2010-11)
    Sprouting allows woody plant species to persist in a site after a wide range of disturbances (e.g. prolonged fire), where opportunities for seedling establishment are limited. A study to investigate long-term effects of ...
  • Smith, MD; Van Wilgen, BW; Burns, CE; Govender, N; Potgieter, ALF; Andelman, S; Biggs, HC; Botha, J; Trollope, WSW (Oxford University Press on behalf of the Institute of Botany, Chinese Academy of Sciences and the Botanical Society of China, 2012-05)
    The long-term effects of changing fire regimes on the herbaceous component of savannas are poorly understood but essential for understanding savanna dynamics. We present results from one of the longest running (>44 years) ...
  • Komba, Julius; Anochie-Boateng, Joseph; O'Connell, Johan; Verhaeghe, Benoit (Springer, 2016-09)
    Enrobé à Module Élevé (EME) technology, a High Modulus Asphalt (HiMA), was originally developed in France. The technology is primarily suitable for construction of heavily trafficked routes, airports and container terminals. ...
  • Steenkamp, K; Wessels, Konrad J; Archibald, S; Von Maltitz, Graham P (CSIR, 2008-11)
    Satellite-derived phenology allows monitoring of terrestrial vegetation on a global scale and provides an integrative view at the landscape level. Understanding these seasonal phenological patterns is essential to (i) the ...
  • Keaikitse, M; Brink, W; Govender, N (PRASA, 2014-11)
    Detection and tracking are important components of many computer vision applications including automated surveillance. Object detection should overcome challenges such as changes in object appearances, illumination, and ...
  • Shatalov, M; Marais, J; Fedotov, I; Tenkam, MJ (InTech Open, 2011-12)
    Longitudinal waves are broadly used for the purposes of non-destructive evaluation of materials and for generation and sensing of acoustic vibration of surrounding medium by means of transducers. Many mathematical models ...
  • Fedotov, IA; Polyanin, AD; Shatalov, M; Tenkama, EM (Pleiades Publishing Ltd., 2010)
    In this work, for analyzing the longitudinal vibrations of a conic rod, the authors used the Rayleigh–Bishop model, which generalizes the Rayleigh model and takes into account both lateral displacements and the shear stress ...
  • Engelbrecht, Jeanine; Inggs, MR (American Geosciences Institute, 2016-08)
    Differential radar interferometry (dInSAR) techniques are well known for their ability to provide mm- to cm-scale measurements of surface deformation. Very accurate measurements of deformation have been achieved in several ...
  • Mubiwa, B; Mokonyama, Mathetha T; Annegarn, H (2015-07)
    Studies have shown that land-use and transportation systems have a two-way dependency. On one hand, the existing land-use structures influence trip distances and transport mode choice, while on the other hand transport ...
  • Aucamp, I; Woodborne, S; Perold, J; Bron, A; Aucamp, S-M (Edward Elgar Publishing, 2011-12)
    At the 1992 United Nations Conference on Environment and Development (or Earth Summit) in Rio de Janeiro, and a decade later at the 2002 World Summit on Sustainable Development (Earth Summit +10) in Johannesburg, the world ...
  • Baumbach, J; Marais, Andre H; Gonçalves, DP (International Council on Systems Engineering South Africa, 2015-09)
    Despite the advances in mature engineering disciplines, some complex systems continue to fail, and sometimes catastrophically. The lack of understanding of a problem and all its constituting elements is a key determinant ...
  • Estuarine and Coastal Research Unit, ECRU (National Research Institute for Oceanology, CSIR, 1982-10)
    This report provides information about Lourens River. The Lourens River was known in the late 17th century as the Tweederivier, since it was the second river crossed on the journey from the Cape Peninsula to the Hottentots ...
  • Milman, YV; Chugunova, S; Goncharuck, V; Luyckx, S; Northrop, IT (Elsevier Science Ltd, 1997)
    The paper reports hardness measurements on WC-6 wt%Co of three different grain sizes in the temperature range from -196 to 900 degrees C. Coarser grades have been found to soften with increasing temperature at a higher ...
  • Myburgh, HC; Olivier, JC (Institute of Electrical and Electronic Engineers (IEEE), 2009-05)
    This work proposes a near-optimal hard output neural network based iterative Maximum Likelihood Sequence Estimation (MLSE) equalizer, based on earlier work by the authors, able to equalize single carrier 4-QAM signals in ...
  • Myburgh, HC; Olivier, JC (Institute of Electrical and Electronics Engineering (IEEE), 2009-05)
    This work proposes a neural network based iterative Maximum Likelihood Sequence Estimation (MLSE) equalizer, able to equalize signals in M-arry Quadrature Amplitude Modulation (M-QAM) modulated systems in a mobile fading ...
