Information management systems (digital libraries/repositories, learning management systems, content management systems) provide key technologies for the storage, preservation and dissemination of knowledge in its various ...

This dissertation researches current approaches to photo sharing. We have found that most current methods of photo sharing are not as compelling as traditional photo sharing - with the increasing in popularity of digital ...

Recent studies have shown that the social context in which people play digital multiplayer games has an effect on their experience. Whether co-players are in the same location ("co-located") or in different locations ...

Our initial study indicates that successful integration of new communication medium into South African schools is not only challenging from the financial point of view, but also in terms of designing tools that fit within ...

Visualizations that show the shape of and spatial relationships between layers of surfaces are useful to oceanographers studying water masses or oncologists planning radiation treatments. The shape of and distances between ...

This thesis seeks to contribute to the field of learning management system (LMS) development in tertiary educational institutions, particularly to advance the adoption of learning management systems (LMSes) by exploring ...

The study of human evolution centres, to a large extent, around the study of fossil morphology, including the comparison and interpretation of these remains within the context of what is known about morphological variation ...

This study investigates the complexity of various reduction and synthesis Petri net transformations. Transformations that preserve liveness and boundedness are considered. Liveness and boundedness are possibly the two most ...

In this thesis, a new class of temporal probabilistic modelling, called evolving dynamic Bayesian networks (EDBN), is proposed and demonstrated to make technology easier so as to accommodate both experts and non-experts, ...

Presence has various definitions, but can be understood as the sensation that a virtual environment is a real place, that the user is actually in the virtual environment rather than at the display terminal, or that the ...

The phenomenal emergence of several heterogeneous wireless networks and technologies has allowed users to have access to IP services anywhere, at anytime, from any network and with whatever terminal they use. This computing ...

In a process control environment, hatch processes, as opposed to continuous processes, are characterised by multi-product manufacturing lines which often involve frequent product changes. One component of batch control ...

Wireless local and metropolitan area network (WLAN/WMAN) technologies, more specifically IEEE 802.11 (or wireless fidelity, WiFi) and IEEE 802.16 (or wireless interoperability for microwave access, WiMAX), are well-suited ...

By encoding 2D bar codes that store URL links, SMS or plain text, 2D visual tags link infonnation about objects in the physical world to online or offline content. The existence of physical world hyperlinks in the fonn of ...

Low resourced languages, such as South Africa's isiXhosa, have a limited number of digitised texts, making it challenging to build language corpora and the information retrieval services, such as search and translation ...

The user interface is a very important component in a piece of software as it is the layer which allows user interaction with the underlying functionality. Within the domain of digital libraries modification to the interface ...

BACKGROUND: Centralised resources such as GenBank and UniProt are perfect examples of the major international efforts that have been made to integrate and share biological information. However, additional data that adds ...

We designed and developed a Collaborative Annotation System for Proteins called DAS Writeback, which extends the Distributed Annotation System (DAS) to provide the functionalities of adding, editing and deleting annotations. ...

Information technology (IT) has become one of the key technologies for economic and social development in any organization. Therefore the management of Information technology incidents, and particularly in the area of ...

This research set out to determine the feasibility of using Java to create a tool that could perform paper-to-electronic format conversion by vectorizing the lines in a raster image of an architectural floor plan. The tool ...
