  • Goliath, Elroy Mario (Stellenbosch : Stellenbosch University, 2002-03)
    ENGLISH ABSTRACT: This study describes the design, construction, complete industrialisation and operation of a dual bed vacuum swing adsorption (VSA) demonstration plant, which operates at atmospheric and sub-atmospheric ...
  • Van der Westhuysen, A. J. (Stellenbosch : University of Stellenbosch, 2002-03)
    ENGLISH ABSTRACT: In this study the numerical short wave model SWAN is evaluated for application to a selected coastal region in South Africa. The aim of this study was to evaluate the degree of accuracy with which SWAN ...
  • Van Heerden, Jacobus P. (Jacobus Petrus) (Stellenbosch : Stellenbosch University, 2002-03)
    ENGLISH ABSTRACT: Flotation was introduced early in the zo" century as a separation process for extracting valuable minerals from grinded ore. Today flotation is a dominant mineral concentration method and is used for ...
  • Migeotte, Gunther (Stellenbosch : Stellenbosch University, 2002-03)
    ENGLISH ABSTRACT: This work is concerned with the hydrodynamic design of hydrofoil-assisted catamarans. Focus is placed on the development of new and suitable design methods and application of these to identify the most ...
  • Du Toit, J. A. (Jacques Andre) (Stellenbosch : Stellenbosch University, 2002-03)
    ENGLISH ABSTRACT: The dissertation presents an alternative approach to the control of power electronic converters. The conventional approach is to use a centralized controller with one or more measurement systems providing ...
