A Digital Identity Management System
(University of the Western Cape, 2007)The recent years have seen an increase in the number of users accessing online services using communication devices such as computers, mobile phones and cards based credentials such as credit cards. This has prompted most ... -
Credit Card Transactions Fraud Detection, and Machine Learning: Modelling Time with LSTM Recurrent Neural Networks
(University of the Western Cape, 2007)In recent years, topics such as fraud detection and fraud prevention have received a lot of attention on the research front, in particular from plastic card issuers. The reason for this increase in research activity can ... -
Towards a chereme based dynamic South African sign language gesture recognition system
(University of the Western Cape, 2007)Hand gestures are a natural and intuitive way of human to human communication. Motivated by the achievements made towards automatic speech recognition, and by the ease with which people sign, many researchers started ... -
Application of Several Time Series Methods to Three Important Financial Time Series
(University of the Western Cape, 2007)This study is concerned with three different financial time series over an eight year period, namely: the government repurchase rate, the Rand-Dollar exchange rate and the Allshare Index. The aim is to better understand ... -
End-to-end single-rate multicast congestion detection using support vector machines
(2008)IP multicast is an efficient mechanism for simultaneously transmitting bulk data to multiple receivers. Many applications can benefit from multicast, such as audio and videoconferencing, multi-player games, multimedia ... -
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 ... -
Ellection markup language (EML) based tele-voting system
(University of the Western Cape, 2009)Elections are one of the most fundamental activities of a democratic society. As is the case in any other aspect of life, developments in technology have resulted changes in the voting procedure from using the traditional ... -
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 ... -
Semi-synchronous video for deaf telephony with an adapted synchronous codec
(University of the Western Cape, 2009)As Information and Communication Technology (ICT) matures, communication services must be improved to meet the needs of all types of users. For some uses, current Video over Internet Protocol (IP) brings unsatisfactory ... -
Inexpensive mobile technologies to empower rural farmers with m-agriculture
(University of the Western Cape, 2010)Market information and established communication between seller and buyer play an important role in business activities. This thesis investigates the Transkei area in the Eastern Cape Province, South Africa to find out ... -
The use of mobile phones as service-delivery devices in sign language machine translation system
(University of the Western Cape, 2010)This thesis investigates the use of mobile phones as service-delivery devices in a sign language machine translation system. Four sign language visualization methods were evaluated on mobile phones. Three of the methods ... -
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 ... -
Mobile presentations with interactive chat for m-Learning
(University of the Western Cape, 2010)Using presentations in an m-Learning environment enables delivery of rich content to a mobile phone learner. This study investigated how to prepare and stream presentations from a desktop computer to a mobile phone in ... -
Numerical Methods for Mathematical Models on Warrant Pricing
(University of the Western Cape, 2010)Warrant pricing has become very crucial in the present market scenario. See, for example, M. Hanke and K. Potzelberger, Consistent pricing of warrants and traded options, Review Financial Economics 11(1) (2002) 63-77 where ... -
Rendering an avatar from sign writing notation for sign language animation
(University of the Western Cape, 2010)This thesis presents an approach for automatically generating signing animations from a sign language notation. An avatar endowed with expressive gestures, as subtle as changes in facial expression, is used to render the ... -
An investigation into the appropriateness of using agile processes to build an educational management information system
(University of the Western Cape, 2010)Since there was a need for an Educational Management Information System (EMIS) in the Ministry of Education in Afghanistan, we designed and implemented a prototype for use in the ministry and investigated the appropriateness ... -
