  • Semi-automatic extraction of primitive geometric entities from point clouds 

    Goussard, Charl Leonard (Stellenbosch : Stellenbosch University, 2001-12)
    ENGLISH ABSTRACT: This thesis describes an algorithm to extract primitive geometric entities (flat planes, spheres or cylinders, as determined by the user's inputs) from unstructured, unsegmented point clouds. The ...

  • Simulating the effect of wind on the performance of axial flow fans in air-cooled steam condenser systems 

    Fourie, Neil (Stellenbosch : Stellenbosch University, 2014-12)
    ENGLISH ABSTRACT: The use of air-cooled steam condensers (ACSCs) is the preferred cooling method in the chemical and power industry due to stringent environmental and water use regulations. The performance of ACSCs is ...

  • Simulation and control implications of a high-temperature modular reactor (HTMR) cogeneration plant 

    Tshamala, Mubenga Carl (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: Traditionally nuclear reactor power plants have been optimised for electrical power generation only. In the light of the ever-rising cost of dwindling fossil fuel resources as well the global polluting ...

  • Simulation based calibration of turbo-charger boost control 

    Pienaar, Schalk Willem (Stellenbosch : University of Stellenbosch, 2007-12)
    Electronic engine control systems utilise tables, or maps, of data to determine the set-points of the various actuators on the engine and to calculate the values of variables that cannot be directly measured. To ensure ...

  • Simulation of a syngas from coal production plant coupled to a high temperature nuclear reactor 

    Botha, Frederick Johannes (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: In light of the rapid depletion of the world’s oil reserves, concerns about energy security prompted the exploration of alternative sources of liquid fuels for transportation. One such alternative is ...

  • The simulation of the flow of polymer melt in lomolding 

    Dymond, Jacques Andrew Dryden (2004-12)
