      ENGLISH ABSTRACT: In this thesis the design, implementation and practical testing of an autolanding system responsible for landing a quadrotor Unmanned Aerial Vehicle (UAV) on a moving platform are presented. The goal ...

    • Automated mobile water leakage assessment system 

      Erwee, Jurie Johannes (2016-12)
      ENGLISH ABSTRACT: Despite humanity’s absolute reliance on the increasingly scarce resource of potable water, 25.4% of South Africa’s water is lost due to leaks in the distribution network before it reaches the consumer. ...

    • Automated parameter extraction for Single Flux Quantum integrated circuits with LVS 

      Roberts, Rebecca Mimi Catherina (Stellenbosch : Stellenbosch University, 2015-03)
      ENGLISH ABSTRACT: Thorough layout verification of superconductor integrated circuits goes beyond design rule checking and parameter value extraction. The former is used to verify adherence to process design rules, and the ...

    • Automated pediatric cardiac auscultation 

      De Vos, Jacques Pinard (Stellenbosch : University of Stellenbosch, 2005-03)
      Most of the relevant and severe congenital cardiac malfunctions can be recognized in the neonatal period of a child’s life. The delayed recognition of a congenital heart defect may have a serious impact on the long-term ...

    • Automated reading of high volume water meters 

      Ulyate, Jessica (Stellenbosch : University of Stellenbosch, 2011-03)
      ENGLISH ABSTRACT: Accurate water usage information is very important for municipalities in order to provide accurate billing information for high volume water users. Meter reading are currently obtained by sending a ...

    • Automated real-time performance feedback and time study using computer vision technology 

      Von Petersdorff, Hagen Alexander (Stellenbosch : Stellenbosch University, 2011-10)
      ENGLISH ABSTRACT: This final year project report describes the creation of a computer vision solution to assess worker performance in a manual labour environment. Time-study data is gathered by the system and performance ...

    • Automated stratigraphic classification and feature detection from images of borehole cores 

      Van der Walt, Stefan Johann (Stellenbosch : University of Stellenbosch, 2005-03)
      This thesis describes techniques proposed for analysing images of borehole cores. We address two problems: firstly, the automated stratigraphic classification of cores based on texture and secondly, the location of thin ...

    • Automatic alignment and error detection for phonetic transcriptions in the African speech technology project databases 

      De Villiers, Edward (Stellenbosch : University of Stellenbosch, 2006-03)
      The African Speech Technology (AST) project ran from 2000 to 2004 and involved collecting speech data for five South African languages, transcribing the data and building automatic speech recognition systems in these ...

    • The automatic and unconstrained segmentation of speech into subword units 

      Van Vuuren, Van Zyl (Stellenbosch : Stellenbosch University, 2014-03)
      ENGLISH ABSTRACT: We develop and evaluate several algorithms that segment a speech signal into subword units without using phone or orthographic transcripts. These segmentation algorithms rely on a scoring function, termed ...

    • Automatic classification of spoken South African English variants using a transcription-less speech recognition approach
