The automated functional and performance analysis of communication systems specified with some Formal Description Technique has long been the goal of telecommunication engineers. In the past SDL and Petri nets have been ...
The subjective response of people living with HIV to illness narratives in VR
(2004)
This dissertation reports on the results on an exploratory investigation into the potential efficacy of VR as both a support mechanism to people living with HIV I AIDS, as well its capabilities as an emotive medium. Two ...
A meta-authoring tool for specifying behaviour in virtual reality environments
(2004)
In this dissertation, we explore methods for empowering non-programmers with the ability to develop their own virtual environment applications. We explored some of the existing systems to determine what methodologies have ...
Using access information in the dynamic visualisation of web sites
(2004)
Log file analysis provides a cost-effective means to detennine web site usage. However, current methods of displaying log analysis results tend to be limited in that they either contain no reference to a web site's structure, ...
A web browsing workload model for simulation
(2004)
The simulation of packet switched networks depends on accurate web workload models as input for network models. We derived a workload model for traffic generated by an individual browsing the web. We derived the workload ...
Model driven segmentation and the detection of bone fractures
(2004)
The introduction of lower dosage image acquisition devices and the increase in computational power means that there is an increased focus on producing diagnostic aids for the medical trauma environment. The focus of this ...
Specification and verification of systems using model checking and Markov reward models
(2004)
This thesis examines Markov reward models, a formalism based on continuous time Markov chains, and it's usage in the generation and analysis of service levels. The particular solution technique we employ in this thesis is ...
Interactive cultural story-telling virtual environments using San stories
(2004)
Story-telling is being used for the preservation of culture, and interactive story-telling in particular is attractive for its ability to provide the user with a hands-on experience. We explored the feasibility of interactive ...
Visual query tools for uncertain data in space and time
(2004)
The aim of our project was to develop query and visualisation tools for this archive of African art. Our query system had to be designed to cope with different degrees of uncertainty in data, both in time and space. One ...
