  • Greben, JM (Elsevier Science B.V, 1991-11)
    This paper originated from the author's dissatisfaction with the way the discrete Fourier transform is usually presented in the literature. Although mathematically correct, the physical meaning of the common representation ...
  • Greben, JM (UKSS, 2009)
    It has become common to describe complexity science as a new approach to many scientific questions that are less amenable to the usual “mechanistic view” of reality in science. However, we believe that the contrast implied ...
  • Ittmann, HW; Van Dyk, FE; Meyer, IA; Janse Van Rensburg, SJ (Operations Research Society of South Africa (ORSSA), 2007)
    Apart from work in the mining industry during the 1950s, the first real Operations Research (OR) group in South Africa was established at CSIR in the early 1960s. Those initially involved in this group played a significant ...
  • Ittmann, HW; Sarma Yadavalli, VS (Wiley, 2010-06)
    The history and current activities of the Operations Research Society of South Africa (ORSSA) is presented in this chapter
  • Debba, Pravesh; Carranza, EJM; Stein, A; Van der Meer, FD (Free and Open Source Software for Geospatial Conference (FOSS4G), 2008-09)
    This research describes a quantitative methodology for deriving optimal exploration target zones based on a probabilistic mineral prospectivity map. In order to arrive at out objective, we provide a plausible answer to the ...
  • Debba, Pravesh; Cho, Moses A; Mathieu, Renaud SA (IEEE, 2009-08)
    This paper uses simulated annealing and focus on the spectral angle mapper (SAM), to demonstrate how the separability of two mean spectra from different species can be increased by choosing the bands that maximize the ...
  • Debba, Pravesh (2010-05)
    The presentation was an the University of Pretoria to geology students. It focused on ways to design optimal sampling schemes to target specific minerals.
  • Debba, Pravesh (2012-07)
    The presentation made to Wits Statistics Department was on common classification methods used in the field of remote sensing, and the use of remote sensing to design optimal sampling schemes for field visits with applications ...
  • Debba, Pravesh; Carranza, EJM; Stein, A; Van der Meer, FD (2009-08)
    This research discusses a novice method for sampling geochemicals to characterize mine tailings. Researchers model the spatial relationships between a multi-element signature and abundance estimates of secondary iron-bearing ...
  • Debba, Pravesh; Carranza, EJM; Stein, A; Van der Meer, FD (IEEE, 2009-07)
    The paper describes a novice method for sampling geochemicals to characterize mine tailings. The author’s model the spatial relationships between a multi-element signature and, as covariates, abundance estimates of secondary ...
  • Cooper, Antony K (2008-05)
    This workshop was conceived with the aim of discussing what an address actually is and exploring the possibility of developing an international address standard across the various domains that use addresses. This paper ...
  • Freiboth, H; Goedhals-Gerber, LL; van Dyk, E; Dodd, M (LM-SCM 2014 XII. International Logistics and Supply Chain Congress, 2014-10)
    A large amount of fruit and money is lost every season due to breaks in the South African fruit export cold chain. With food security becoming an ever growing concern, especially in developing countries like South Africa, ...
  • Engelbrecht, GN; Schmitz, Peter MU; Bean, WL (2009-09)
    The development of performance indicators in the military is dependent on the measurability of its associated strategies. Von Clausewitz (1976) argues that nations are either at war or preparing for war. It follows that ...
  • Cho, Moses A; Debba, Pravesh; Mutanga, O; Dudeni-Tlhone, N; Magadla, T; Khuluse, SA (Elsevier, 2012-06)
    Indigenous forest degradation is regarded as one of the most important environmental issues facing Sub-Saharan Africa and South Africa in particular. We tested the utility of the unique band settings of the recently launched ...
  • Gupta, R; Das, Sonali (CSIR, 2008-03)
    This paper estimates Bayesian Vector Autoregressive (BVAR) models, both spatial and non-spatial (univariate and multivariate), for the twenty largest states of the US economy, using quarterly data over the period 1976:Q1 ...
  • Gupta, R; Das, Sonali (Springer, 2010-10)
    This paper estimates Bayesian Vector Autoregressive (BVAR) models, both spatial and non-spatial (univariate and multivariate), for the twenty largest states of the US economy, using quarterly data over the period ...
  • Gupta, R; Das, Sonali (SASA 2008, 2008-10)
    Bayesian methods are influenced by choice of prior. None-the-less, their importance cannot be disregarded in light of current exercise and existing other literature . The way forward is to try other large scale Bayesian ...
  • Greben, JM; Elphinstone, C; Holloway, Jennifer P; De Villiers, R; Ittmann, HW; Schmitz, Peter MU (Acad Science South Africa, 2005-03)
    During the last three elections in South Africa, the CSIR was involved in the prediction of the final outcome on the basis of early results. In this paper, we describe the methods used by the CSIR in these elections and ...
  • Cooper, Antony K; Greben, JM; Van Den Bergh, F; Gledhill, Irvy MA; Cannoo, BR; Steyn, WJVDM; De Villiers, R (South African Conference on Computational and Applied Mechanics SACAM08, 2008-03)
    A variety of armour units are used to protect breakwaters, piers and other harbour infrastructure, serving both to absorb the impact of violent seas and to reduce overtopping. A common type of armour unit is the dolos. ...
  • Ditsela, J; Coetzee, S; Cooper, Antony K (2011-06)
    An address assignment scheme identifies the components that make up an address and describes how values are assigned to these components. Address assignment schemes vary from country to country and there is often a strong ...
