• Calibration of heliostats using a drone. 

      Gouws, Jurgens Erik (Stellenbosch : Stellenbosch University, 2018-12)
      ENGLISH ABSTRACT: The aim of this thesis was to investigate the theoretical feasibility of calibrating heliostats using a drone. Doing so would require the following: (1) First show that it is possible to identify ...
    • Low impedance characterisation and modeling of high power LDMOS devices 

      Malan, Pieter Jacob De Villiers (Stellenbosch : University of Stellenbosch, 2005-12)
      In RF power transistor characterisation, the designer is confronted with low impedance measurements (typically from 1 Ohm to 12 Ohm). These transistors are contained in metal-ceramic packages of which the lead widths ...
    • Measuring, refining and calibrating speaker and language information extracted from speech 

      Brummer, Niko (Stellenbosch : University of Stellenbosch, 2010-12)
      ENGLISH ABSTRACT: We propose a new methodology, based on proper scoring rules, for the evaluation of the goodness of pattern recognizers with probabilistic outputs. The recognizers of interest take an input, known to ...
    • Simulation of tribological interactions in bonded particle-solid contacts 

      Van Wyk, Geritza (Stellenbosch : Stellenbosch University, 2012-12)
      ENGLISH ABSTRACT: In this study, tool forces from rock cutting tests were numerically simulated through a discrete element method (DEM) in association with PFC3D™. Tribological interactions such as contact, shearing, ...
