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 ...
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 ...
The development of an ARM-based OBC for a nanosatellite
(Stellenbosch : University of Stellenbosch, 2007-12)
Next-generation nanosatellites are becoming a very cost effective solution to
gain access to space. Modern manufacturing technology together with low
power low cost devices makes the development of nanosatellites, using ...
A comparison of Gaussian mixture variants with application to automatic phoneme recognition
(Stellenbosch : University of Stellenbosch, 2007-12)
The diagonal covariance Gaussian Probability Density Function (PDF) has been a very
popular choice as the base PDF for Automatic Speech Recognition (ASR) systems. The
only choices thus far have been between the spherical, ...
Development and control of a 3-axis stabilised platform
(Stellenbosch : University of Stellenbosch, 2007-03)
The successful control of a three-degree-of-freedom gyroscope is presented for the
application of steering and stabilising a platform mounted underneath an airship.
The end goal is to stabilise a camera for earth observation ...
The fabrication of PBCO buffered step-edge Josephson junctions
(2007-03)
A major challenge in the design and operation of High Temperature Superconducting
(HTS) devices is the fabrication of reproducible Josephson junctions with good IcRn products.
One objective of this thesis was to fabricate ...
