  • SAURAN : a new resource for solar radiometric data in Southern Africa 

    Brooks, Michael J.; Du Clou, Sven; Van Niekerk, Wikus L.; Gauche, Paul; Leonard, Corli; Mouzouris, Michael J.; Meyer, Riaan; Van der Westhuizen, Nic; Van Dyk, Ernest E.; Vorster, Frederik J. (Energy Research Centre, 2015)
    A new resource for sun strength data in Southern Africa has been established with the commissioning of a regional network of solar monitoring stations. The Southern African Universities Radiometric Network (SAURAN) is an ...

  • Energy supply in Malawi : options and issues 

    Taulo, John L.; Gondwe, Kenneth Joseph; Sebitosi, Adoniya Ben (Energy Research Centre, 2015)
    Inadequate energy supply is one of the major problems confronting Malawi and limiting its social, economic and industrial development. This paper reviews the current status of energy supply and demand in Malawi; examines ...

  • Heat treatment of TI-6AL-4V produced by laserCUSING 

    Becker, Thorsten; Van Rooyen, Melody; Dimitrov, Dimitri (SAIIE, 2015)
    LaserCUSING® is a selective laser melting (SLM) process that is capable of manufacturing parts by melting powder with heat input from a laser beam. LaserCUSING demonstrates potential for producing the intricate geometries ...

  • Microstructure and mechanical properties of direct metal laser sintered TI-6AL-4V 

    Becker, Thorsten Hermann; Beck, Mathias; Scheffer, Cornie (SAIIE, 2015)
    Direct metal laser sintering (DMLS) is a selective laser melting (SLM) manufacturing process that can produce near net shape parts from metallic powders. A range of materials are suitable for SLM; they include various ...

  • Heat transfer to MHD oscillatory dusty fluid flow in a channel filled with a porous medium 

    Prakash, O. M.; Makinde, O. D.; Kumar, Devendra; Dwivedi, Y. K. (Indian Academy of Sciences, 2015)
    In this paper, we examine the combined effects of thermal radiation, buoyancy force and magnetic field on oscillatory flow of a conducting optically thin dusty fluid through a vertical channel filled with a saturated porous ...

  • Numerical investigation into entropy generation in a transient generalized Couette flow of nanofluids with convective cooling 

    Mkwizu, M. H.; Makinde, O. D.; Nkansah-Gyekye, Yaw (Indian Academy of Sciences, 2015)
    This work investigates the effects of convective cooling on entropy generation in a transient generalized Couette flow of water-based nanofluids containing Copper (Cu) and Alumina (Al 2O3) as nanoparticles. Both First and ...

  • A Water Flow Meter for Smart Metering Applications 

    Muller, Regardt I; Booysen, Marthinus J. (South African Conference on Computational and Applied Mechanics - SACAM, 2014-01)
    The availability and depletion of natural resources is increasingly punted as the limiting factor for sustainability. A lot of focus, especially in drought-stricken countries, is placed on water conservation. One way to ...

  • Constrained particle swarm optimization using a bi-objective formulation 

    Venter, Gerhard; Haftka, R. T. (Springer Verlag, 2010)
    This paper introduces an approach for dealing with constraints when using particle swarm optimization. The constrained, single objective optimization problem is converted into an unconstrained, bi-objective optimization ...

  • An algorithm for fast optimal Latin hypercube design of experiments 

    Viana, Felipe A. C.; Venter, Gerhard; Balabanov, Vladimir (Wiley-Blackwell, 2010-04)
    This paper presents the translational propagation algorithm, a new method for obtaining optimal or near optimal Latin hypercube designs (LHDs) without using formal optimization. The procedure requires minimal computational ...
