  • Coal and climate change: Potential for carbon capture and storage in South Africa 
    Hietkamp, S (2006-06)
    The highly concentrated CO2 streams currently produced at Sasol are well suited for CO2 sequestration without further processing except for pressurising. The potential in South Africa for biological sequestration is limited ...
  • Coal pillar design procedures 
    York, G; Canbulat, I; Jack, BW (2000-03)
    Examination of collapsed pillar cases outside of the empirical limits of Salamon and Munro’s in situ database has highlighted the need for additional parameters to be considered in the design of coal pillars. These include ...
  • Coal value chain - simulation model 
    Fourie, M; van Rensburg, JJ (Sasol Technology & Sasol Mining, 2005-08)
    This presentation focuses on setting of tools to facilitate optimisation and integration of coal value chain. It also focuses on maximising coal to gas yield and supply optimum coal quality
  • Coastal and marine research and capacity building 
    Francis, J; Celliers, Louis; Rosendo, S (United Nations Environment Programme ; Nairobi Convention Secretariat, 2015)
    Most, if not all, of the recommendations contained in this State of the Coast Report, relies on two cross-cutting and fundamental qualities. Firstly, managers, decision- and policy-makers and the various end-users have ...
  • Coastal dunes of South Africa 
    Tinley, KL (National Scientific Programmes Unit: CSIR, 1985)
    A synthesis is presented on the ecology of South African coastal dune ecosystems, which comprise about 80% of South Africa's 3 000 km shoreline. A detailed description of the extent, structure and functioning of these ...
  • Coastal flooding levels in South Africa 
    Theron, A; Rautenbach, C; Maherry, A; Rossouw, M (CSIR, 2015-04-22)
    The study for the CSIR & DEA – Phases 1 & 2 Research Study: South African Coastal Vulnerability Assessment present on the Coastal flooding levels in South Africa.
  • Coastal remote sensing – towards integrated coastal research and management 
    Lück-Vogel, Melanie (2012-10)
    The CSIR’s coastal systems research group conducts trans-disciplinary research from basic research up to the provision of policies and technical guidelines to prepare the coastal communities in South Africa and beyond ...
  • Coaxial end-launched and microstrip to partial H-plane waveguide transitions 
    Kloke, KH; Joubert, J; Odendaal, JW (IEEE Xplore, 2015-08)
    Conventional rectangular waveguides are commonly used for high power and other microwave and millimeter wave applications. Their use at lower frequencies has been limited by their bulky nature. A new type of compact waveguide ...
  • Code-switched English pronunciation modeling for Swahili spoken term detection 
    Kleynhans, N; Hartman, W; Van Niekerk, D; Van Heerden, C; Schwartz, R; Tsakalidis, S; Davel, M (Elsevier, online, 2016-05)
    We investigate modeling strategies for English code-switched words as found in a Swahili spoken term detection system. Code switching, where speakers switch language in a conversation, occurs frequently in multilingual ...
  • Coefficient of work-hardening in stage-IV 
    Nabarro, FRN (Pergamon-Elsevier Science Ltd, 1994-04-15)
    The theory of work hardening in stage IV depends on the relation between the relative misorientation Psi of neighbouring subgrains and the plastic strain gamma (Psi = B gamma exp). The value of the constant B is suggested ...
  • Cofimvaba: Innovative and systemic technology application in rural, education focused, agri-based development initiatives 
    Van Rensburg, J (2012-10)
    In this presentation the author shares current learning on the use of more targeted and systemic ICT for development as well as broader technology for development education and LED-focused interventions in the science, ...
  • Cognitive radio-based transmission energy management in Wi-Fi nodes 
    Olwal, TO; Montsi, L (2012-10)
    The CSIR has developed a cognitive radio-based transmission energy management algorithm that can be used to manage the energy consumption of Wi-Fi networks in rural and remote communities in South Africa. The project ...
  • Coherence optimization and its limitations for deformation monitoring in dynamic agricultural environments 
    Eng, Jeanine; Inggs, MR (IEEE, 2016-12)
    Differential interferometry techniques are well known for its ability to provide centimeter to millimeter scale deformation measurements. However, in natural and agricultural areas, the presence of vegetation and the ...
  • Coherent excitation of vibrational levels using ultra short pulses 
    De Clercq, LE; Botha, LR; Du Plessis, A; Rohwer, EG (South African Institute of Physics (SAIP), 2009-07)
    The purpose of this study was to develop a model of the coherent excitation of the first few vibrational modes in the electronic ground state of the molecule. The model will be used in combination with an optimization ...
  • COL816: Develop specifications for a portable counting seismometer to be implemented routinely in mines underground 
    Lynch, RA (2002-06)
    The SIMRAC project COL816 investigated the feasibility of a small, independent device monitoring local seismicity and extracting similar activity information to what can be recorded by a temporary network of seismometers. ...
