Virtual human modelling and animation for real-time sign language visualisation
(University of the Western Cape, 2008)This thesis investigates the modelling and animation of virtual humans for real-time sign language visualisation. Sign languages are fully developed natural languages used by Deaf communities all over the world. These ... -
The Complexity of Splay Trees and Skip Lists
(University of the Western Cape, 2008)Our main results are that splay trees are faster for sorted insertion, where AVL trees are faster for random insertion. For searching, skip lists are faster than single class top-down splay trees, but two-class and multi-class ... -
Foreign Exchange Option Valuation under Stochastic Volatility
(University of the Western Cape, 2009)The case of pricing options under constant volatility has been common practise for decades. Yet market data proves that the volatility is a stochastic phenomenon, this is evident in longer duration instruments in which the ... -

The efficacy of the Eigenvector approach to South African sign language identification
(University of the Western Cape, 2010)The communication barriers between deaf and hearing society mean that interaction between these communities is kept to a minimum. The South African Sign Language research group, Integration of Signed and Verbal Communication: ... -
Visualization of microprocessor execution in computer architecture courses: a case study at Kabul University
(University of the Western Cape, 2010)Computer architecture and assembly language programming microprocessor execution are basic courses taught in every computer science department. Generally, however, students have difficulties in mastering many of the concepts ... -
South African sign language recognition using feature vectors and Hidden Markov Models
(University of the Western Cape, 2010)This thesis presents a system for performing whole gesture recognition for South African Sign Language. The system uses feature vectors combined with Hidden Markov models. In order to constuct a feature vector, dynamic ... -
