  • Implementation of an SDH simulator using SDR 

    Brandt, A. D. (Stellenbosch : University of Stellenbosch, 2006-03)
    A Synchronous Digital Hierarchy (SDH) point-to-point bi-directional link was implemented at a base Synchronous Transfer Mode level 1 (STM 1) signal rate. The full STM-1 multiplexer was implemented and the functional ...

  • Improving Automatic Position Reporting System (APRS) throughput and reliability 

    Van Tonder, Hendrik Petrus (Stellenbosch : University of Stellenbosch, 2005-03)
    The Automatic Position Reporting System (APRS) is a well-established packet communication protocol that offers users a graphical position display system and a peer-to-peer textual message service. APRS is used in temporary ...

  • In-core temperature measurement for the PBMR using fibre-bragg gratings 

    De Villiers, Gerrit Johannes (Stellenbosch : University of Stellenbosch, 2009-03)
    The PBMR has called for research into the possibility of distributed in-core temperature measurement. In this thesis, several methods for distributed temperature measurement in high-pressure, -radiation and -temperature ...

  • Increasing distributed generation penetration when limited by voltage regulation 

    Nye, Jonathan Mark (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: This work investigated the influence of photo-voltaic generators on the voltage control of distribution feeders and the methods that can be used to increase the maximum penetration levels of these feeders. ...

  • Independent formant and pitch control applied to singing voice 

    Calitz, Wietsche Roets (Stellenbosch : University of Stellenbosch, 2004-12)
    ENGLISH ABSTRACT: A singing voice can be manipulated artificially by means of a digital computer for the purposes of creating new melodies or to correct existing ones. When the fundamental frequency of an audio signal ...
