  • Wall, K; Bhagwan, J; Ive, O; Kirwan, F (IWA Publishing, 2012-09)
    South African research finds that social franchising partnerships could address many challenges in the operation and maintenance of water services infrastructure. Franchising trains those on-site, and also provides backup ...
  • Krug, Marjolaine J; Swart, S; Hermes, J (American Geophysical Union, 2018-06)
    Off the east coast of South Africa, robotic ocean gliders deployed in the Agulhas Current capture new data that help us better understand how energy dissipates in the ocean.
  • Cooper, Antony K; Coetzee, Serena (Springer, 2020-04)
    Publicly-available mobile data can be used to derive fine grain commuting and travel patterns. These types of data include geocoded or geotagged discrete units of communication: messages, posts, tweets, status updates, ...
  • 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 ...
  • Van Wyk, Llewellyn V (2008-03)
    The notion of “open building” arose out of a counter movement within the Congrès Internationaux d’Architecture Moderne (CIAM) to the promotion of modern mass housing theories in post-First World War Europe. The opponents ...
  • Ndwe, J; Barnard, E; Dlodlo, M; Mashao, D; Kuun, C; Sharma, A (Springer, 2008-09)
    The OpenPhone project aims to design an Interactive Voice Response (IVR) health information system that enables people who are caregivers for HIV/AIDS infected children to access relevant information by using a telephone ...
  • Kamdar, A; Kienhöfer, F; Emwanu, B; Heyns, G; Nordengen, Paul A (IEOM Society International, 2018-10)
    This paper presents operational improvement outcomes of the Road Transport Management System (RTMS) in South Africa. The RTMS is a voluntary, self-regulation scheme that encourages consignees, consignors and road transport ...
  • Austin, LM (2006)
    There are approximately 50,000 urine diversion (UD) toilets in South Africa. Emptying the vaults implies that the faecal material must be handled, usually with spades or rakes. Should the material be used for agricultural ...
  • 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
  • Chetty, N; Ramkilowan, A; Griffith, DJ; Lysko, MD (Italian Society of Remote Sensing, 2013-04)
    South Africa’s fresh water resources are under threat by Harmful Algal Blooms (HABs). A comprehensive and cost effective method for wide area detection and monitoring of HABs is therefore needed to manage and where possible ...
  • 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 ...
  • Mema, V; Hlabela, Simon P; Marx, S; Rust, C (Dr. Mahalingam College of Engineering and Technology, 2015-08)
    Energy intensive technology, such as activated sludge plants, is fast becoming a high-cost item of municipal budgets amidst the rising electricity tariffs and vulnerable demand-supply dynamics in South Africa. The introduction ...
  • Semmelink, CJ; Groenewald, M; Du Plessis, E (National Department of Transport, South Africa, 1994-03)
    The report deals with the site investigations in connection with the compaction standards, that is a comparison between actual in situ dry densities achieved compared to specification requirements, for road layer work for ...
  • Paige-Green, P; Pinard, MI (2012-09)
    Sustainable upgrading of unsealed roads to a low volume sealed standard is best accomplished by maximising the use of the in situ materials within the prevailing road environment. Over the years and under traffic loading, ...
