  • Van Der Merwe, A; Van Dyk, E; Van Vuuren, J (Operations Research Society of South Africa (ORSSA) and Operations Research practice in Africa (ORPA), 2007-09)
    The goal of the study is to lend decision support to management a a wine cellar in three areas of expertise, with Wamakersvallei Winery serving as a special case study. This decision support system is to be delivered in ...
  • Meyer, IA; Marais, Mario A (2014-10)
    A number of factors complicate the ability to deliver sustainably on development interventions. Multiple role players are involved, the performance of implementation agencies are measured over the short- to medium term and ...
  • Lanz, EJ; Van Dyk, FE; Van Vuuren, JH (40th ORSSA Conference 2011, 2011-09)
    The mission of the Global Foodbanking Network is to work together to alleviate world hunger by developing national networks of foodbanks and strengthening foodbanking around the world. In the South African context, the ...
  • Turpin, SM; Marais, Mario A (Stellenbosch University Library and Information Service, 2004)
    This paper compares a number of theoretical models of decision-making with the way in which senior managers make decisions in practice. Six prominent decision-makers were interviewed about their own decision-making style ...
  • Uys, H; Biercuk, MJ; VanDevender, AP; Ospelkaus, C; Meiser, D; Ozeri, R; Bollinger, JJ (American Physical Society, 2010-11)
    The authors present theoretical and experimental studies of the decoherence of hyperfine ground-state superpositions due to elastic Rayleigh scattering of light off resonant with higher lying excited states. They demonstrate ...
  • Uys, H; Biercuk, M; Van Devender, AP; Ospelkaus, C; Meiser, D; Ozeri, R; Bollinger, JJ (SAIP 2010, 2010-09)
    This paper investigates the decoherence of superpositions of hyperfine states of 9Be+ ions due to spontaneous scattering of off-resonant light. It was found that, contrary to conventional wisdom, elastic Raleigh scattering ...
  • Roux, FS (CSIR, 2012-06)
    This report present the presentation on deconstructing quantum decoherence in atmospheric turbulence. The focus was on the classical and quantum scintillation, time vs propagation distance, current paradigm: Paterson model, ...
  • Ndlovu, GF; Asante, JKO; Roos, WD; Hillie, KT (SAIP, 2011-07)
    An Ultra-high Vacuum Variable Temperature Scanning Tunnelling Microscope was used to study the growth mechanism of Antimony on vicinal Cu polycrystalline samples. The STM data after deposition of 0.3 ML Sb at 300°C showed ...
  • Cronje, J (IVCNZ 2015 Image and Vision Computing, 2015-11)
    The work in this paper address the problem of removing non-uniform motion blur from a single image. The motion vector for an image patch is estimated by using a convolutional neural network (CNN). All the predicted motion ...
  • Napier, JAL; Malan, DF; Sellers, E; Daehnke, A; Hildyard, MW; Dede, T; Shou, K-J (1998-12)
    The investigation of the behaviour of the fracture zone surrounding deep level gold mine stopes is detailed in three main sections of this report. Section 2 outlines the ongoing study of fundamental fracture process and ...
  • Davel, MH; Barnard, E (PRASA 2004, 2004-11)
    The authors define a novel g-to-p prediction algorithm that utilises the concept of a 'default phoneme': a grapheme which is realised as a specific phoneme significantly more often than as any other phoneme. They found ...
  • Casini, G; Straccia, U (Association for the Advancement of Artificial Intelligence, 2013)
    Defeasible inheritance networks are a non-monotonic framework that deals with hierarchical knowledge. On the other hand, rational closure is acknowledged as a landmark of the preferential approach to non-monotonic reasoning. ...
  • Britz, K; Varzinczak, I (Centre for Artificial Intelligence Research, 2013-01)
    Nonmonotonic logics are usually characterized by the presence of some notion of `conditional' that fails monotonicity. Research on nonmonotonic logics is therefore largely concerned with the defeasibility of argument forms ...
  • Britz, K; Varzinczak, I (2012-06)
    Historically, approaches to defeasible reasoning have been concerned mostly with one aspect of defeasibility, viz. that of arguments, in which the focus is on normality of the premise. In this paper we are interested in ...
  • Moodley, K; Meyer, T; Varzinczak, IJ (ACM, 2012-10)
    Classical reasoning for logic-based KR (Knowledge Representation) systems is in general, monotonic. That is, there is an assumption in these systems that there is complete information about a domain. This means that they ...
  • Mashapa, MG; Chetty, N; Sinha Ray, S (American Scientific Publishers, 2012-05)
    The effect of defect complexes on the stability, structural and electronic properties of single-walled carbon nanotubes and boron nitride nanotubes is investigated using the ab initio pseudopotential density functional ...
  • Motaung, DE; Kortidis, I; Papadaki, D; Nkosi, SS; Mhlongo, GH; Wesley-Smith, J; Malgas, GF; Mwakikunga, BW; Coetsee, E; Swart, HC; Kiriakidis, G; Ray, SS (Elsevier, 2014-08)
    We present a systemic study on the structural, optical and magnetic properties of the un-doped and Mn doped ZnO thin films grown by aerosol spray pyrolysis at different deposition times. XRD profilinghas shown that the ...
  • Jule, L; Dejene, F; Ali, AG; Roro, Kitessa T; Mwakikunga, Bonex W (Elsevier, 2017-07)
    In this work, electron paramagnetic resonance (EPR) experiment on undoped ZnO and Al doped ZnO (AZO) nanoparticles prepared by facile sol–gel method were investigated. The effects of the Al concentration on room temperature ...
  • Van Wyk, Llewellyn V; Knoetze, Theunis P (2007-05)
    In exploring the possibility of establishing a theory of construction for development, this paper reviews concepts of theory and theory formulation, contextualises optimal developmental modalities, describes the role of ...
