Automatic phoneme recognition of South African English
(Stellenbosch : Stellenbosch University, 2004-03)
ENGLISH ABSTRACT: Automatic speech recognition applications have been developed for many languages in
other countries but not much research has been conducted on developing Human Language
Technology (HLT) for S.A. ...
The instrumentation and initial analysis of the short-term control and stability derivatives of an ASK-I3 glider
(Stellenbosch : University of Stellenbosch, 2004-03)
ENGLISH ABSTRACT: This thesis describes the process followed to determine the short-term control and stability
derivatives of an ASK-13 glider (ZS-GHB). The short-term control and stability derivatives are
obtained by ...
Modular approach to the development of a two-way radio receiver system
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: The preliminary development of a FM radio receiver module is discussed. An existing narrowband
system operating between 48MHz and 50MHz will be replaced. Digital components were

Bidirectional converter for a stirling energy system
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: This thesis discusses a 23 kW three-phase AC bus system that is utilized together with the
“Stirling Energy System (SES) Integrated Solar Dish-Stirling Module” to function as a
mini-grid for off-grid ...
Microwave data transmission by means of an optimal bandwidth multichannel QPSK system
(Stellenbosch : Stellenbosch University, 2004)
ENGLISH ABSTRACT: The increase in the complexity and functionality of new satellites leads to a
growing demand for a digital communication system operating at a much higher bit
rate than before. The main purpose of this ...
A three-phase AC/AC matrix converter system
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: The thesis discusses the analysis and design of a three-phase-to-three-phase direct
AC-AC matrix converter. A background study of the various matrix converter topologies
and their modulation strategies ...
Wavelet-based speech enhancement : a statistical approach
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: Speech enhancement is the process of removing background noise from speech signals. The
equivalent process for images is known as image denoising. While the Fourier transform is
widely used for speech ...
Transformerless series dip/sag compensation with ultracapacitors
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: This thesis covers the development of a transformerless series dip compensator. Of all known power
quality problems, voltage dips are the greatest reason for concern. Series injection dip compensators
offer ...
