An aircraft based emulation platform and control model for LEO satellite antenna beam steering
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: A joint project between the KU Leuven and Stellenbosch Universities was at
the time of this thesis underway to develop a space borne electronically beam
steerable antenna and the associated ground-space ...
Investigation of a high-speed serial bus between satellite subsystems
(Stellenbosch : Stellenbosch University, 2003-04)
ENGLISH ABSTRACT: The aim of this thesis is to investigate the implementation of a high-speed serial bus based
on the IEEE Std 1394-1995 specification for use in a microsatellite.
Earth observation microsatellites carry ...
Handwritten signature verification using hidden Markov models
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: Handwritten signatures are provided extensively to verify identity for all types of transactions
and documents. However, they are very rarely actually verified. This is because of
the high cost of ...
Application of an extended Huygens' principle to scattering discontinuities in waveguide
(Stellenbosch : Stellenbosch University, 2004-04)
ENGLISH ABSTRACT: The implementation and verification of a recently proposed Huy gens' principle in hollow
lossless waveguide is described. The extended Huygens' principle is applicable
to the scattering effect of ...
An EMC framework for South Africa
(Stellenbosch : Stellenbosch University, 2003-04)
ENGLISH ABSTRACT: This thesis pursues the establishment of a new Electromagnetic Compatibility (EMC)
framework for South Africa. The aim of this framework is to ensure that the user is
protected from sub-standard products ...
Evaluating the applications of spatial audio in telephony
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: Telephony has developed substantially over the years, but the fundamental auditory model
of mixing all the audio from di erent sources together into a single monaural stream has not
changed since the ...
Development of a FEM waveguide code, incorporating Fast Frequency Techniques, for numerical synthesis
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: A computational tool for numerical synthesis via optimization is developed. Only
two port waveguide devices are considered. The Finite Element Method (FEM) is
used for the electromagnetic analysis. ...
Analysis and implementation of the speaker adaptation techniques : MAP, MLLR, and MLED
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: The topic of this thesis is speaker adaptation, whereby speaker-independent speech models
are adapted to more closely match individual speakers by utilising a small amount of
data from the targeted ...
Development of a high speed PCI data capture card for the SUNSAT I ground station
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: The primary payload of the University of Stellenbosch's micro-satellite, SUNSAT I,
was a high quality imager, capable of taking stereoscopic images of the surface of
the earth. Although the orbit of ...
A constant power, load independent microwave source
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: In the past few years, a need for consulting on microwave heating has surfaced. Since most
specialised microwave components are imported, this adds a hefty price tag in developing the
infrastructure ...
