High performance computing: Recent submissions

  • Harmse, H; Britz, K; Gerber, A (Springer, 2018-10)
    A challenge in ontology engineering is the mismatch in expertise between the ontology engineer and domain expert, which often leads to important constraints not being specified. Domain experts often only focus on specifying ...
  • Nkosi, Mpho C; Lysko, Albert A; Dlamini, Sabelo V (IEEE, 2018-12)
    Networks have become an important feature of our day-to-day to life and therefore, user experience is an imperative goal to be achieved by network operators. Load balancing is a method of improving network performance, ...
  • Bogaers, Alfred EJ; Jansen van Rensburg, GJ; Marquart, R; Skatulla, S (2018-09)
    In this paper, we outline the implementation of Hibler’s visco-plastic (VP) sea ice model into OpenFOAM, an opensource finite-volume modelling toolkit. Hibler’s visco-plastic model is arguably the most widely used description ...
  • Musehane, Ndivhuwo M; Oxtoby, Oliver F; Reddy, BD (Academic Press, 2018-11)
    In this work, droplet–droplet interaction is modelled using a multi-scale approach which couples multiphase flow simulation using a volume of fluid method to a surface thin film model operating on the sub-grid scale. The ...
  • Maúre, GA; Pinto, I; Ndebele-Murisa, MR; Muthige, Mavhungu S; Lennard, C; Nikulin, G; Dosio, A; Meque, AO (IOP Publishing Ltd, 2018-02)
    Results from an 25 regional climate model simulations from the Coordinated Regional Downscaling Experiment (CORDEX) Africa initiative are used to assess the projected changes in temperature and precipitation over southern ...
  • Modiba, Rosinah; Chauke, H; Ngoepe, P (2017-09)
    The study on the Ti-based materials and its application has been the interest of many research industries. These alloys are known to have an ordered B2 phase at high temperatures and transform to a stable low B19 martensitic ...
  • Nkoana, R; Engelbrecht, FA; Marean, CW (2015-09)
    Reconstructing the glacial maximum climates of the Cape south coast region of South Africa is important within the context of understanding the evolution of modern humans in this region. Simulating the Last Glacial Maximum ...
  • Modiba, Rosinah M; Chauke, HR; Ngoepe, PE (2017-09)
    The ab initio density functional theory approach was employed to study the effect of Ni, Ir or Pd addition to the TiPt shape memory alloy. The supercell approach in VASP was used to substitute Pt with 6.25, 18.75, 25.00, ...
  • Mabakane, Mabule S; Moeketsi, Daniel M; Lopis, Anton S (2017-12)
    This paper presents a case study on the scalability of several versions of the molecular dynamics code (DL_POLY) performed on South Africa‘s Centre for High Performance Computing e1350 IBM Linux cluster, Sun system and ...

  • Sithole, Happy M; Ubbink, Onno (CSIR, 2017-10)
    This presentation discusses how high-performance computing (HPC) combined with machine learning and artificial intelligence, present opportunities to non-traditional industries. It showcases how the CSIR’s renewed focus ...
  • Adeleke, Oluwatoyin A; Karry, KM; Michniak-Kohn, BB; Monama, Nkwe O (2015-10)
    The purpose of this abstract is to design and characterize a thermodynamically stable mouth-dissolving film containing isoniazid employing in silico and in vitro techniques. Isoniazid (solubility = 140 mg/mL and log P = ...
  • Naidoo, Mogesh; Sibiya, Bhekizizwe A; Bird, T; Nekhwalivhe, M; Netshandama, J; Mahlatji, M (National Association for Clean Air, South Africa (NACA), 2017-10)
    Municipalities are required to develop an Air Quality Management Plan (AQMP) in order to work towards mitigating the negative impacts of air quality on human health and the environment. The 2016 AQMP for the City of ...
  • Musehane, Ndivhuwo M; Oxtoby, Oliver F; Reddy, DB (Curran Associates, Inc., 2016-10)
    In this work, droplet-droplet interaction is modelled using a multiphase flow computational fluid dynamics approach coupled with a reduced order surface thin-film model. An existing multiphase flow model based on a multiple ...
  • Focke, RW; De Villiers, Johan P; Inggs, MR (IEEE Xplore, 2016-07)
    In this paper, the authors investigate speeding up the execution time of Interval Algebra (IA) mechanically-steered multistatic and multisite radar scheduling using a general-purpose graphical processing unit (GP-GPU). ...
  • Prnjat, O; Becker, B; Barbera, R; Kanellopoulos, C; Koumantaros, K; Mayo-Garcia, R; Ruggier, F (IEEE, 2015-05)
    CHAIN-REDS, an EU co-funded project, focuses on promoting and supporting technological and scientific collaboration across different e-Infrastructures established and operated in various continents. The project implemented ...
  • Suliman, Ridhwaan; Peake, N (Not available, 2015-07)
    The deformation of slender elastic structures due to the bulk motion of fluid around it is a common multiphysics problem encountered in many applications. In this work we implement two computational FSI approaches in a ...
  • Smith-Godfrey, S (Taylor&Francis, 2016)
    Oceans are increasingly gaining in importance in terms of enabling international trade via linking sellers and buyers. The behaviour patterns of such linking enablers on the oceans are receiving more attention from a ...
  • Grobler, J; Engelbrecht, AP; Kendall, G; Yadavallie, VSS (Elsevier, 2015-04)
    This paper expands on the concept of heuristic space diversity and investigates various strategies for the management of heuristic space diversity within the context of a meta-hyper-heuristic algorithm in search of greater ...
