An open source model for teaching environments incorporating wireless devices
(2007)
Attempts have been made at bridging the digital divide in schools using desktop PC systems without much success. As a result many computer laboratories sit empty. There are many reasons for these failures. Often there are ...
A capacity limited, cognitive constructionist model of virtual presence
(2007)
The capacity Limited, Cognitive Constructionist (CLCC) model of presence is proposed as an information processing model of presence, which is demonstrated to have more theoretical power than extant models. The CLCC model ...
Measuring the applicability of open data standards to a single distributed organisation : an application to the COMESA Secretariat
(2008)
This dissertation develops data metrics that represent the extent to which data standards can be applied to an organization's data. The research identified key issues that affect data interoperability or the feasibility ...
Universal web application server
(2007)
The growth of the World Wide Web has in large part been made possible by the technologies that power it. These are the Web servers and Web browsers that many take for granted. Each has evolved to support the changing needs ...
Distributed authentication to preserve privacy through smart card based biometric matching
(2000)
This thesis focuses on privacy concerns, specifically those relating to the storage and use of biometrics. These concerns result from the fact that biometric information is unique. This uniqueness makes the biometric a ...
An extended spreadsheet paradigm for data visualisation systems, and its implementation
(2000)
We describe a data visualisation system which uses spreadsheets as its user interface metaphor. Similar systems implemented in the past were hampered by the contradiction between an imperative formula language and the ...
A lightweight interface to local grid scheduling systems
(2009)
Many complex research problems require an immense amount of computational power to solve. In order to solve such problems, the concept of the computational Grid was conceived. Although Grid technology is hailed as the next ...
ROLAND : a tool for the realistic optimisation of local access network design
(1999)
Investment in the local access network represents between 50% and 70% of capital investment of a telecommunications company. This thesis investigates algorithms that can be used to design economical access networks and ...
Parallel fluid dynamics for the film and animation industries
(2009)
The creation of automated fluid effects for film and media using computer simulations is popular, as artist time is reduced and greater realism can be achieved through the use of numerical simulation of physical equations. ...
