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 ...
Flight control system for a variable stability blended-wing-body unmanned aerial vehicle
(Stellenbosch : University of Stellenbosch, 2009-03)
This thesis presents the analysis, design, simulation and practical implementation of a
novel control system for a variable stability blended-wing-body unmanned aerial vehicle.
The aircraft has a moveable centre of mass ...
Design of a single-sided axial flux PM in-wheel electric vehicle machine with non-overlap stator windings
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: With the current worldwide energy problems electric vehicles are set to replace conventional combustion engine vehicles. Electric vehicles with gearless in-wheel mounted brushless permanent magnet motors ...
Design of a haptic controller for excavators
(Stellenbosch : University of Stellenbosch, 2009-03)
The input orientation of the excavators in use today usually comprises
two joysticks that control the actuator links individually. In order to perform
an excavation task, several different combinations of joystick ...
An LDPC error control strategy for low earth orbit satellite communication link applications
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: Low earth orbit (LEO) satellite communication presents a unique environment
which inherently di ers from most other communication channels.
Due to the varying orbital patterns of LEO satellites the link ...
Fast accurate diphone-based phoneme recognition
(Stellenbosch : University of Stellenbosch, 2009-03)
Statistical speech recognition systems typically utilise a set of statistical models of subword
units based on the set of phonemes in a target language. However, in continuous
speech it is important to consider co-articulation ...
Autonomous docking for a satellite pair using monocular vision
(Stellenbosch : University of Stellenbosch, 2009-03)
Autonomous rendezvouz and docking is seen as an enabling technology. It allows, among
others, the construction of larger space platforms in-orbit and also provides a means for the
in-orbit servicing of space vehicles.
In ...
High-power broadband absorptive waveguide filters
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: This dissertation presents a synthesis method for broadband high-power absorptive microwave
lters by cascading a wide stop-band wa e-iron lter with an absorptive harmonic
pad.
The classical image ...
Hover control for a vertical take-off and landing vehicle
(Stellenbosch : University of Stellenbosch, 2009-03)
This thesis details the development and comparison of two linear control systems
that performhover control for a vertical take-off and landing unmanned
aerial vehicle.
A non-linear mathematical model of the aircraft ...
An eCos based flight software for a nanosatellite
(Stellenbosch : University of Stellenbosch, 2009-03)
The nanosatellite is build-up of subsystems and payloads (defined as satellite nodes)
connected together into the OBC using CAN bus as the main communication protocol.
The flight software application is required to run ...
