  • Litvin, IA; Khilo, NA; Forbes, A; Belyi, VN (Optical Society of America, 2010-02)
    The authors report on two resonator systems for producing Bessel–like beams with longitudinally dependent cone angles (LDBLBs). Such beams have extended propagation distances as compared to conventional Bessel– Gauss beams, ...
  • Rens, GB; Varzinczak, IJ (PRASA 2009, 2009-12)
    The authors are developing a new logic (DyMoDeL) for reasoning about dynamic agents with stochastic action, partial observation, knowledge-of and degree-of-belief-in a state of affairs. Development of the syntax and semantics ...
  • Bopape, Mary-Jane M; Engelbrecht, F (South African Society for Atmospheric Sciences, 2011-09)
    A nonhydrostatic sigma coordinate model (NSM) is currently being developed at the Council for Scientific and Industrial Research (CSIR), using the equation set of Engelbrecht et. al. (2007), for purposes of simulating ...
  • Pattinson, T; Majozi, T (Elsevier, 2009)
    A novel operational policy, the Process Intermediate Storage operational policy, is introduced and used to synthesize, schedule and design multipurpose batch plants. The model is based on the State Sequence Network and ...
  • Casini, G; Meyer, T; Moodley, K; Sattler, U; Varzinczak, I (Springer International Publishing, 2015-10)
    In recent years, various approaches have been developed for representing and reasoning with exceptions in OWL. The price one pays for such capabilities, in terms of practical performance, is an important factor that is yet ...
  • Stavropoulos, CC (Cooperative Scientific Programmes: CSIR, 1977-09)
    The telemetering of information over long distances from unattended environmental monitoring equipment at remote sites can be difficult to carry out using conventional high frequency radio communication. This is because ...
  • Maina, JW; Denneman, E; De Beer, Morris (2008-07)
    Pavement response modelling based on the theory of linear elasticity was introduced in South Africa in the late 1960's and early 1970's. Since that time, continuous developments took place, and today it is possible to ...
  • Stafford, W; Brent, A (Energy Research Centre, 2010-11)
    The global bioenergy industry is advancing rapidly. New technologies and potential feedstocks are being proposed that aim for bioenergy to contribute to a wider range of economic, social, and environmental objectives. ...
  • Veerasamy, N; Taute, B (Information Security South Africa, 2009-04)
    With technological change and advancement, attackers are increasingly becoming more sophisticated in their attack strategies and techniques. Other global factors and developments also impact the line of attack. This paper ...
  • Jeffrey, L; Henry, G; McGill, J (Struik Nature, 2015-01)
    This chapter provides some basic geological and mining background information and sets the scene in terms of the key operational challenges experienced by local coal miners and the role that geophysics can play in addressing ...
  • Audouin, M; Burns, M; Weaver, A; Le Maitre, David C; O'Farrell, P; du Toit, R; Nel, J (Edward Elgar, 2015-09)
    In this chapter the authors explore two elements which arguably underlie all aspects of sustainability science, namely: an emphasis on the relationships between social, ecological and economic aspects in a systemic view ...
  • Fourie, S; Van Schoor, Abraham M; Vogt, D; van der Walt, J; Jikelo, A; Campbell, G; Du Plessis, A (Coaltech, 2015-01)
    This chapter introduces a range of geophysical methods that may be applicable to coal mining and exploration problems. The focus of these discussions is on emphasising the link between geology and physics – and how the ...
  • Funke, Nicola S; Claassen, Marius (2017-04)
    The specific mission supported by this Road Map is to unlock South Africa's maritime potential through research, development and innovation.
  • Van Wyk, Llewellyn V (Alive2green, 2010-08)
    By recognising the specific environmental challenges facing South Africa, mindful of the government‘s commitment to reducing South Africa‘s Greenhouse gas emissions, and acknowledging the need to build social cohesion, the ...
  • Grobbelaar, C.S; Billinggum, P.A (NBRI/CSIR, 1975)
    The most basic function of a building is to protect its occupants and their possessions from the weather. It is no wonder therefore that a leaking root, or finishes marred by dump, leave the owner feeling cheated- his ...
  • Billingham, PA (NBRI/CSIR, 1977)
    When man first began to build shelters for himself about 800 years ago he concentrated on providing effective walls and roof. The floor go-t scant attention because it was already provided by the earth. The first soft ...
  • Donaldson, GW; Billingham, PA (1973)
    The words ‘built on a firm foundation' have become part of the language and most people would unhesitatingly agree that a house has to have a foundation' without perhaps understanding exactly why. If one were to place an ...
  • Addis, B.J (NBRI/CSIR, 1980)
    Paving is used to cover ground to eliminate dust, mud or erosion and to facilitate the movement of traffic. It can also be used to control the moisture content of the underlying soil around houses built on unsable soil ...
  • Ferreira, T.M; Billingham, P.A (1973)
    The difference between sound and noise varies from one human being to another. Noise, then, is simply unwanted sound and to understand how it can be combatted we must know more about its nature. A guide of acceptable levels ...
  • Cromarty, R.E; Billingham, P.A (NBRI/CSIR, 1985)
    Thousands of years ago primitive man made use of some of the colourful materials that he found around him to stain his body and clothing. He also decorated the walls of his cave with pictures of hunters and wild animals ...
