Information visualisation uses interactive three-dimensional (3D) graphics to create an immersive environment for the exploration of large amounts of data. Unlike scientific visualisation, where the underlying physical ...

An integrated payroll-pension system designed specifically for commercial users with limited computer resources is presented. This system combines in a single system the usual functions of both a payroll system and a pension ...

In this research, we present a modelling technique that can efficiently facilitate anomaly detection that will help call analysts and managers with adaptive decision-making. We developed and implemented a Data 'fransformation ...

The emergence of virtual reality and related tools enables the fundamental infrastructure to begin building virtual cities, which can provide an interactive simulation and analysis environment for planning and management ...

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 ...

Computational uid dynamics can be used to reproduce the complex motion of fluids for use in computer graphics, but the simulation and rendering are both highly computationally intensive. In the past performing these tasks ...

The emerging sensor networking applications are predicting the deployment of sensor devices in thousands of computing elements into multi-technology and multi-protocol platforms. Access to information will be available not ...

The lack of communication facilities in developing countries is a constraint to social, political and economic empowerment of the people. However, advances in technology promise to deliver voice, video and data communication ...

The term cultural heritage spaces incorporates places, objects and practices of cultural and historical significance. Examples include the Southern African rock art heritage sites. Rock art is an archaeological term used ...

Academic performance prediction modelling provides an opportunity for learners' probable outcomes to be known early, before they sit for final examinations. This would be particularly useful for education stakeholders to ...

This text responds to the increasing demand for frameworks to support the design and evaluation of virtual worlds which are effective in their particular learning context by developing, a meta-theoretical framework for ...

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 ...

Character animation is the process of modelling and rendering a mobile character in a virtual world. It has numerous applications both off-line, such as virtual actors in films, and real-time, such as in games and other ...

This dissertation builds upon the ideas introduced by Liben-Nowell and Kleinberg in The Link Prediction Problem for Social Networks [42]. Link prediction is the problem of predicting between which unconnected nodes in a ...

Lack of adaptive-predictor models in software development renders the decision-making process complex, principally when evaluating investment options. Prior work has presented various approaches which are still non-integrated, ...

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 ...

The current medley of interoperability protocols is potentially problematic. Each protocol is designed by a different group, each provides a single service, and has its own syntax and vocabulary. Popular protocols such as ...

Engergy usage has become an important issue in wireless communication systems. The energy-intensive nature of wireless communication has spurred concern over how best systems can make the most use of this non-renewable ...

This thesis attempts to address the problem of mixed querying in CLIR. It proposes mixed-language (language-aware) approaches in which mixed queries are used to retrieve most relevant documents, regardless of their languages. ...

Mobile computing, by necessity, introduces its own paradigm of interaction and design complexities. Rather than trying to re-create miniature desktop systems, designers should focus on creating mobile software: software ...
