  • Debba, Pravesh (2009-07)
    This presentation presented to the SASA Eastern Cape Chapter at Rhodes University posses two questions: (a) how could estimates of abundances of spectrally similar iron-bearing oxide/hydroxide/sulfate minerals in complex ...
  • Stylianides, T (Elsevier Science B.V, 1998-10)
    This paper describes a model which has been applied in practice to determine an optimal plan for clinker capacity expansion. The problem was formulated as an integer linear program aiming to determine the optimal number, ...
  • Deiss, JA; Berman, Robert J; Kienhofer, F (2018-09)
    A performance-based standards (PBS) framework evaluates actual on-road performance of a vehicle, allowing the length and mass of a vehicle to exceed prescriptive legislation, without compromising on vehicle safety and ...
  • Dudeni-Tlhone, N; Ramoelo, Abel; Cho, Moses A; Debba, Pravesh; Mathieu, Renaud SA (2010-10)
    This paper uses the spatial and the least squares (Analysis of Covariance-ANCOVA) regression methods to evaluate the important environmental factors in estimating quality grass for grazing (based on the nitrogen (N) content ...
  • Ortmann, FG; Van Vuuren, JH; Van Dyk, FE (Orion – Johannesburg, 2006-04)
    A description is provided of work performed as part of the fruit logistics infrastructure project commissioned by the South African Deciduous Fruit Producers’ Trust and coordinated by the South African Council for Scientific ...
  • Cooper, Antony K; van Rooyen, MH; Clarke, DG; Liebenberg, EC (CSIR, 1987-09)
    Geographically referenced (geo-referenced) information consists of all information that refers to the man-environment system and that can be localized in space and time. The basic entity of geo-referenced information is ...
  • Rakitianskaia, AS; Olivier, MS; Cooper, Antony K (2011-08)
    Online social spaces have become very popular in the past couple of decades. With the great numbers of users in the online environments it becomes obvious that the human factor plays an important role in the social structure ...
  • Cannoo, BR; Gledhill, Irvy MA; Cooper, Antony K; Greben, JM (South African Conference on Computational and Applied Mechanics SACAM08, 2008-03)
    The protection of coastal structures is important to South Africa. The dynamics of breakwaters is a topic that is becoming amenable to numerical study, in terms of the motion of multiple interlocking structures under wave ...
  • Cooper, Antony K; Sebake, N (2018-10)
    South Africa's commitment to meeting the Sustainable Development Goal (SDG) 11, “Make cities and human settlements inclusive, safe, resilient and sustainable”, requires the country to have an understanding of the range of ...
  • Letebele, MO; Maseloma, RC; Mokonyama, Mathetha T (Southern African Transport Conference, 2009-07)
    Fuel costs are a significant component of a public transport fare. It is therefore of critical importance for measures aimed at containing household public transport expenditure to explore alternative ways of reducing fuel ...
  • Greben, JM; Cooper, Antony K; Gledhill, Irvy MA; de Villiers, R (CSIR, 2008-11)
    The authors have applied various numerical techniques to describe the stability of breakwater structures under the exposure of waves. These studies are intended to get a better understanding of the parameters playing a ...
  • 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 ...
