    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...
