  • Klompje, Gideon (Stellenbosch : University of Stellenbosch, 2006-12)
    Speech is the primary and most natural means of communication between human beings. With the rapid spread of technology across the globe and the increased number of personal and public applications for digital equipment ...
  • Ferreira, Thomas Ignatius (Stellenbosch : University of Stellenbosch, 2009-03)
    This thesis relates to the successful development of an unmanned terrestrial vehicle (UTV) capable of operating in an obstacle ridden environment. The primary focus of the project is on the specific path planning algorithms. ...
  • Marais, Johannes Izak Frederik (Stellenbosch : University of Stellenbosch, 2006-12)
    The open-ended coaxial probe is revisited as a broadband measurement system for general high frequency permittivity measurements. Three coaxial probes were developed that are suited for the measurement of both liquids ...
  • Grobbelaar, Johannes Jacobus (Stellenbosch : University of Stellenbosch, 2011-03)
    ENGLISH ABSTRACT: The objective of the thesis is the development of a phase noise measuring system that makes use of crosscorrelation and averaging to measure below the system hardware noise floor. Various phase noise ...
  • Theunissen, M. W. (Marthinus Wilhelmus) (Stellenbosch : Stellenbosch University, 2002-04)
    ENGLISH ABSTRACT: The field of topic spotting in conversational speech deals with the problem of identifying "interesting" conversations or speech extracts contained within large volumes of speech data. Typical applications ...
  • Dirkse van Schalkwyk, W. J. (Stellenbosch : Stellenbosch University, 2001-03)
    ENGLISH ABSTRACT: Unshielded distribution lines has a poor performance during lightning activity. Lightning initiates flashovers between the phases and earth and causes line breakers to trip several times during a ...
  • Winter, Pieter (Stellenbosch : University of Stellenbosch, 2005-03)
    Position calculation of mobile objects has challenged engineers and designers for years and is still continuing to do so. There are many solutions available today. Probably the best known and most widely used outdoor ...
  • De Jongh, Willem Adriaan (Stellenbosch : Stellenbosch University, 2001-04)
    ENGLISH ABSTRACT: Current global trends in government, industry and popular OpInIOn indicate that recycling will become essential in the future. Vacuum pyrolysis is a new technology with many recycling applications that ...
  • Fourie, Gert (Stellenbosch : Stellenbosch University, 2002-12)
    ENGLISH ABSTRACT: This thesis presents results of a study on the small-signal stability of a single-machine infinite-bus power system. Conditions of generator loading and network impedance are identified that require ...
  • De Villiers, Wernich (Stellenbosch : Stellenbosch University, 2001-12)
    ENGLISH ABSTRACT: A frequency domain Power Line Carrier (PLC) simulation program, with the ability to simulate signal attenuation including the coupling equipment, was developed. This simulation program was put to the ...
  • Du Toit, Daniel Josias (Stellenbosch : Stellenbosch University, 2011-12)
    ENGLISH ABSTRACT: This thesis investigates the viability of constructing a solid-state transformer (SST) with a series-input, parallel-output connection of full-bridge, three-level ying-capacitor converters. It focusses ...
  • Visser, Bernardus Johannes (Stellenbosch : Stellenbosch University, 2008-12)
    This thesis presents the design of a control system for the autonomous precision landing of an unmanned aerial vehicle aided by an infra red camera for precision position measurements. An optimal kinematics state estimator ...
  • Urban, Graeme John (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: Energy efficiency and the move to renewable energy resources are of vital importance in growing profitable and sustainable economies. In recent years, greater emphasis has been placed on institutions, ...
  • Van der Westhuyzen, Petrus Johannes (Stellenbosch : University of Stellenbosch, 2006-12)
    In order to rapidly detect, monitor and predict changes in milk as it ferments, sensors would need to be designed specifically for milk. To this end, invasive surgical stainless steel probes were investigated and the ...
  • Rossouw, Daniel Johannes (Stellenbosch : University of Stellenbosch, 2010-12)
    ENGLISH ABSTRACT: Flanged coaxial probes are widely used to conduct accurate, broadband permittivity measurements of various dielectric materials. A metrology study, discussed in [1], revealed that small perturbations ...
