Human-computer interface using a web camera
(Stellenbosch : University of Stellenbosch, 2007-12)
In this thesis we present a human-computer interface (HCI) system for disabled
persons using only a basic web camera. Mouse movements are simulated
by small movements of the head, while clicks are simulated by eye
blinks. ...
Rural e-mail system for the Sumbandila satellite
(Stellenbosch : Stellenbosch University, 2007-12)
ENGLISH ABSTRACT: Keywords: digital signal processing, OSI layer, network protocols, embedded systems,
satellite technology
This thesis describes the design and implementation of a rural e-mail system for the ...
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 ...
Pulse power device characterization for amplifier design
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: Bi-polar Si transistors optimized for pulse conditions is still the most popular choice as
amplification element in the final stages of solid-state radar amplifiers in L and S band. With the
radar market ...
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 ...
Optimisation methods applied to compensator placement
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: The optimal placement of different types of compensators on electrical networks is a complex
task faced by network planners and operations engineers. The successful placement of these
devices normally ...
Microwave heating of multiphase materials : modelling and measurement
(Stellenbosch : Stellenbosch University, 2005-12)
ENGLISH ABSTRACT: Both coaxial probe and waveguide (WG) measurement systems for electric and magnetic
material property extraction were investigated. These measurement techniques were used
to determine electrical properties ...
Development of a rotary-wing test bed for autonomous flight
(Stellenbosch : University of Stellenbosch, 2006-03)
This project developed a low-cost avionics system for a miniature helicopter to be used for
research in the field of autonomous flight (UAVs).
Previous work was done on a small, electrically powered helicopter with some ...
