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 ...
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, ...
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 ...
Face recognition using Hidden Markov Models
(Stellenbosch : University of Stellenbosch, 2005-03)
This thesis relates to the design, implementation and evaluation of statistical
face recognition techniques. In particular, the use of Hidden Markov
Models in various forms is investigated as a recognition tool and ...
Evaluation of selected subspace tracking algorithms for direction finding
(Stellenbosch : University of Stellenbosch, 2007-03)
This thesis examines three reduced complexity algorithms for subspace tracking in the context
of radio direction finding. Projection Approximation Subspace Tracking (Yang), the
Fast Data Projection Method (Doukopoulos ...
Estimation of Synchronous Generator Parameters using Time-domain Responses
(Stellenbosch : University of Stellenbosch, 2005-12)
Power system stability simulations are of growing importance for studying the operational
integrity of modern power systems, especially in developing economies where generating and
transmission capacity lead the demand ...
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 ...
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 ...
hp-Adaptation for the FEM Analysis of Waveguides
(Stellenbosch : Stellenbosch University, 2008-03)
The nite element method (FEM) is a powerful tool for the computational analysis of a wide range
of electromagnetic problems. As the complexity of the problems is increased so are the demands
in terms of the computational ...
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 ...
