Autonomous aerobatic flight of a fixed wing unmanned aerial vehicle
(Stellenbosch : University of Stellenbosch, 2007-03)
This thesis relates to the successful development of a flight control system to perform a range of
aerobatic manoeuvres autonomously. The project is the first to try to extend the flight control
capabilities of the ...
Calibration of UV-sensitive camera for corona detection
(Stellenbosch : University of Stellenbosch, 2007-03)
Electrical energy is continuously transported across the world by high voltage transmission lines. These
transmission lines are however subject to losses beside the inherent resistive and dielectric losses. This
additional ...
Evaluation of modern large-vocabulary speech recognition techniques and their implementation
(Stellenbosch : University of Stellenbosch, 2009-03)
In this thesis we studied large-vocabulary continuous speech recognition.
We considered the components necessary to realise a large-vocabulary speech
recogniser and how systems such as Sphinx and HTK solved the ...
Automated pediatric cardiac auscultation
(Stellenbosch : University of Stellenbosch, 2005-03)
Most of the relevant and severe congenital cardiac malfunctions can be recognized
in the neonatal period of a child’s life. The delayed recognition of a congenital heart
defect may have a serious impact on the long-term ...
Advanced modelling of a borehole radar environment with the finite difference time domain method
(Stellenbosch : University of Stellenbosch, 2001-12)
Over the last decade, as the mining industry of South Africa is moving
to ever deeper mines, the borehole radar is becoming an increasingly important
field of research.
In December 2000, Burger completed his thesis on ...
Facial Feature Reconstruction using Structure from Motion
(Stellenbosch : University of Stellenbosch, 2005-03)
Structure from Motion suggests that an object or scene’s three-dimensional
structure can be determined from its observed two-dimensional motion. Human
efforts, manifested in computer algorithms, try to mimic the ...
Adaptation, optimisation and simulation of the CSMA/CA protocol for a low earth orbit satellite UHF link
(Stellenbosch : University of Stellenbosch, 2006-12)
A low earth orbit satellite is to provide the telecommunications link to facilitate email
services to rural areas, where the infrastructure necessary for e-mail is lacking
(e.g. no telephone lines). Communication time ...
Development of dynamically reconfigurable ground station software
(Stellenbosch : University of Stellenbosch, 2007-12)
Applications are normally developed with a specific purpose in mind and when
new features are needed the source code has to be modified, recompiled and
redistributed. It will be more beneficial if new features can be ...
Design Procedures for Series and Parallel Feedback Microwave DROs
(Stellenbosch : University of Stellenbosch, 2007-12)
Clear procedures for designing dielectric resonator oscillators (DROs) are presented in
this thesis, including built examples to validate these design procedures. Both series
and parallel feedback DROs are discussed and ...
Probe characterisation, design and evaluation for the real-time quality Indication of milk
(Stellenbosch : University of Stellenbosch, 2006-12)
In order to rapidly detect, monitor and predict changes in milk as it ferments, sensors would need to be
designed specifically for milk. To this end, invasive surgical stainless steel probes were investigated and
the ...
