  • Ballot, Francis (Stellenbosch : University of Stellenbosch, 2009-03)
    Surfactants are compounds that reduce interfacial surface tension, resulting in detergency, emulsifying, foaming and dispersing properties. Surfactants produced via biochemical processes (biosurfactants) form a niche market ...
  • Bence, Keenan (Stellenbosch : Stellenbosch University, 2011-12)
    ENGLISH ABSTRACT: Biosurfactants are microbially produced molecules that show excellent surface-active properties. Bacillus subtilis ATCC 21332 produces the biosurfactant, surfactin, which exhibits antimicrobial activity ...
  • Van Rooyen, Gert-Jan (Stellenbosch : Stellenbosch University, 2004-04)
    ENGLISH ABSTRACT: Keywords: software-defined radio, SDR, quadrature mixing, quadrature modulation, quadrature demodulation, digital compensation, software radio, direct-digital synthesis, DDS. An often-stated goal of ...
  • Swanepoel, Willie (Stellenbosch : Stellenbosch University, 2011-12)
    ENGLISH ABSTRACT: Strain hardening cement‐based composites (SHCC) are fibre‐reinforced composites designed to form multiple fine cracks under tensile and flexural load. The cracks are controlled to small widths, ...
  • Molapo, Katiso Tokoloho (Stellenbosch : University of Stellenbosch, 2010-12)
    ENGLISH ABSTRACT: Reinforced concrete is susceptible to cracking. This makes it less durable than it would be had it been crack-free. Ingress of harmful substances into reinforced concrete through cracks – which causes ...
  • Cloete, Teunis (Stellenbosch : University of Stellenbosch, 2009-03)
    Clinical gait analysis has been proven to greatly improve treatment planning and monitoring of patients suffering from neuromuscular disorders. Despite this fact, it was found that gait analysis is still largely underutilised ...
  • Malherbe, D.C. (Stellenbosch : University of Stellenbosch, 2007-03)
    The supply of manufactured products depends on tool, die and mould (TDM) manufacturing. The TDM industry provides the machines, tools and equipment necessary to produce most manufactured components. The TDM industry is ...
  • Brink, C.J. (Stellenbosch : University of Stellenbosch, 2004-12)
    ENGLISH ABSTRACT: The primary aim of the research was to determine the optimum diversion location in a curved channel to minimise the abstraction of sediment. The secondary aim was to determine the optimum diversion angle ...
  • Ndovi, Lusungu (Stellenbosch : Stellenbosch University, 2008-12)
    The continued advancement and improvement of software-defined radio technology has been a key factor in furthering research into the implementation of most signal processing algorithms at baseband. Traditionally, these ...
  • Thompson, Geoffrey (Stellenbosch : University of Stellenbosch, 2007-12)
    Research on cranes and crane support structures has been completed at Stellenbosch University’s Structural Division. In order to link the research already completed with that which is practically relevant, an industry ...
  • Schutte, Adriaan Nicholaas (Stellenbosch : University of Stellenbosch, 2009-03)
    A bi-directional, direct conversion switch-mode converter is proposed for use in distributed household renewable energy systems. The converter is intended as the central interface between the household energy system’s low ...
  • Redecker, H. H. (Hans Henning) (Stellenbosch : University of Stellenbosch, 2004-12)
    ENGLISH ABSTRACT: This thesis discusses a 23 kW three-phase AC bus system that is utilized together with the “Stirling Energy System (SES) Integrated Solar Dish-Stirling Module” to function as a mini-grid for off-grid ...
  • Qi, Bing Cui (Stellenbosch : Stellenbosch University, 2001-03)
    ENGLISH ABSTRACT: Lignocellulose is the principal form of biomass in the biosphere and therefore the predominant renewable source in the environment. However, owing to the chemical and structural complexity of lignocellulose ...
  • Uras, Umit (Stellenbosch : Stellenbosch University, 2011-12)
    ENGLISH ABSTRACT: According to recent studies, biochar has the potential to improve soil fertility, mitigate climate change, reduce off-site pollution and assist in managing wastes. The application of biochar to soil is ...
  • Lind, Aingy Chantel (Stellenbosch : University of Stellenbosch, 2009-03)
    The abundance of alkane by-products formed in South Africa presents a feedstock opportunity for the production of a wide range of commercially important products, such as long-chain dioic acids and alcohols. These compounds ...
  • Prah, Ebenezer (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: Development of analytical methods to characterise biodiesel has become central to the overall success of the marketing of biodiesel fuel. In this regard, different bodies including the American Society ...
  • Van der Merwe, Hugo Jacobus (Stellenbosch : Stellenbosch University, 2008-03)
    Automatic bird song recognition and transcription is a relatively new field. Reliable automatic recognition systems would be of great benefit to further research in ornithology and conservation, as well as commercially ...
  • Thomas, Keegan D. (Stellenbosch : University of Stellenbosch, 2005-03)
    The objective of the thesis is to improve the performance prediction of axial compressors, using a streamline throughflow method (STFM) code by modelling the hub and casing wall boundary layers, and additional flow ...
  • Barnard, Daniel David (Stellenbosch : Stellenbosch University, 2013-03)
