    Voltage control of medium to high power three-phase inverter supply systems 

    Jacobs, D. M. (Danver Maxwill) (Stellenbosch : Stellenbosch University, 2001-12)
    ENGLISH ABSTRACT: In this thesis a new voltage control method is developed for a three-phase inverter supply system. The inverter supply system consist of a Permanent Magnet Generator, a three-phase rectifier, a three-phase ...

    Harmonic mixer analysis and design 

    Van der Merwe, Marius (Stellenbosch : Stellenbosch University, 2002-03)
    ENGLISH ABSTRACT: Harmonic mixers are capable of extended frequency operation by mixing with a harmonic of the LO (local oscillator) signal, eliminating the need for a high frequency, high power LO. Their output spectra ...

    Structure from motion estimation using a nonlinear Kalman filter 

    Venter, Chris (Christian Johannes) (Stellenbosch : Stellenbosch University, 2002-12)
    ENGLISH ABSTRACT: Structure from Motion is defined as the problem of extracting the 3d motion of a camera moving through a scene, as well as the 3d structure of the scene, from the image sequence produced by the camera ...

    Investigation of the impact of high frequency transmitted speech on speaker recognition 

    Pool, Jan (Stellenbosch : Stellenbosch University, 2002-04)
    ENGLISH ABSTRACT: Speaker recognition systems have evolved to a point where near perfect performance can be obtained under ideal conditions, even if the system must distinguish between a large number of speakers. Under ...

    Prediction and measurement of power line carrier signal attenuation and fluctuation 

    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 ...

    Establishing a process for the fabrication of high-quality HTc SQUIDs 

    Rottier, P. A. (Pieter Adriaan) (Stellenbosch : Stellenbosch University, 2002-12)
    ENGLISH ABSTRACT: High-temperature (HTc) SQUID magnetometers are used in the biomedical field of magnetocardiography (MCG). The use of MCG enables a much earlier diagnosis of potentially dangerous conditions than the ...

    Simple broadband measurements of balanced loads using a network analyzer 

    Van Rooyen, M. W. (Melchior Werner) (Stellenbosch : Stellenbosch University, 2001-04)
    ENGLISH ABSTRACT: Balanced loads such as antennas normally require baluns when they are measured. For wide band applications, designing and building a balun complicates the measurement and introduces errors. A simple ...
