  • Fast accurate diphone-based phoneme recognition 

    Du Preez, Marianne (Stellenbosch : University of Stellenbosch, 2009-03)
    Statistical speech recognition systems typically utilise a set of statistical models of subword units based on the set of phonemes in a target language. However, in continuous speech it is important to consider co-articulation ...

  • Fast analysis of a compound large reflector antenna 

    Alphonse, Stephanie (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: The o set Gregorian dual re ector antenna is eminently well suited to a radio telescope antenna application as it o ers a narrow beam width pattern (i.e high gain) and good e ciency. The focus of this ...

  • Fast pyrolysis of corn residues for energy production. 

    Danje, Stephen (Stellenbosch : Stellenbosch University, 2011-12)
    ENGLISH ABSTRACT: Increasing oil prices along with the climate change threat have forced governments, society and the energy sector to consider alternative fuels. Biofuel presents itself as a suitable replacement and has ...

  • Fault tolerant adaptive control of an unmanned aerial vehicle 

    Basson, Willem Albertus (Stellenbosch : Stellenbosch University, 2011-12)
    ENGLISH ABSTRACT: This thesis presents the development of an adaptive longitudinal control system for an unmanned aerial vehicle (UAV). The project forms part of a research effort at Stellenbosch University into different ...

  • Fault tolerant flight control of a UAV with asymmetric damage to its primary lifting surface 

    Beeton, Wiaan (Stellenbosch : Stellenbosch University, 2013-12)
    ENGLISH ABSTRACT: In this thesis the design, analysis, implementation, and verification of a fault-tolerant unmanned aerial vehicle (UAV) flight control system which is robust to structural damage causing the natural ...
