The application of information and communication technologies to development (ICT4Dev) is widely believed to have the potential to improve livelihoods in developing regions. Within the field of HCI, it is recognised that ...

The increasing number of cyber security breaches have revealed a need for proper cyber security measures. The emergence of the internet and the increase in overall connectivity means that data is more easily accessible and ...

Stock market trading has garnered much interest over the past few decades as it has been made easier for the general public to trade. It is certainly an avenue for wealth growth, but like all risky undertakings, it must ...

Most Social Media Platforms (SMPs) implement privacy policies that enable users to protect their sensitive information against privacy violations. However, observations indicate that users find these privacy policies ...

The complexity of determining whether a system meets the requirements of its designers has increased with the widespread use of real time concurrent systems. This testing process has however been simplified with the emergence ...

HiLog is a logic-based language which boasts the expressiveness of a higher-order syntax while retaining the simplicity of a first-order semantics. This work examines the suitability of Horn-clause HiLog as a query language ...

An application on a social network may provide a means to avoid the cost, decrease time and increase scale of operation of heritage preservation by motivating users to supply and process the data. This project uses a ...

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 ...

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 ...

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 ...
