Story experience in a virtual San storytelling environment : a cultural heritage application for children and young adults
(2005)
This dissertation explores virtual storytelling for conveying cultural stories effectively. We set out to investigate: (1) the strengths and/or weaknesses of VR as a storytelling medium; (2) the use of a culturally familiar ...
A framework for building spatiotemporal applications in Java
(2001)
A relatively new area of study that first received attention during the past decade explores how spatiotemporal data can be efficiently used in applications and stored in databases. Spatial data includes the locations or ...
A hybrid scavenger grid approach to intranet search
(2009)
According to a 2007 global survey of 178 organisational intranets, 3 out of 5 organisations are not satisfied with their intranet search services. However, as intranet data collections become large, effective full-text ...
Extraction of surface texture data from low quality photographs to aid the construction of virtual reality models of archaeological sites
(2001)
A tool has been designed and implemented to use information extracted from photographs captured using uncalibrated cameras (so-called casual photographs) to fill the occlusions which occur in three-dimensional models of ...
Optimising information retrieval from the web in low-bandwidth environments
(2007)
The Internet has potential to deliver information to Web users that have no other way of getting to those resources. However, information on the Web is scattered without any proper semantics for classifying them and thus ...
Garbage collection of the PLAVA object store
(2002)
This research investigates the implementation of suitable garbage collection schemes for a persistent store. The store that formed the basis for these experiments was the one developed for a Java Virtual Machine known as ...
Incompatibility of lognormal forward-Libor and Swap market models
(2005)
The lognormal forward-Libor and Swap market models were formulated to price caps and swaptions. However, the prices computed by these two models, under equivalent measures, are reported to be unequal. This study investigates ...
Using programming tools in virtual environments
(2002)
Presence is the sense of being in the computer-generated environment. It is regarded as the key to understanding the success of a virtual environment. In this research we focus on desktop virtual environment authoring ...
An extension to optic flow analysis for the generation of computer animated images
(1998)
This dissertation seeks to develop image based animation methods using the technique of optic flow analysis developed for a moving planar object. Image based rendering is presented as a class of algorithm using two dimensional ...
Evaluation of a multiprogramming time sharing system through simulation.
(1975)
The thesis describes the design and implementation of a simulation model. The model is patterned after the EXEC-8 multiprogramming time sharing operating system on the UNIVAC 1106 computer at the computer centre of the ...
