The thesis describes the design and implementation of a PL/I subset compiler which produces a hypothetical stack code as output. The compiler was based on a Pascal compiler developed by N. Wirth and U. Amman of Eidgenössische ...

The UbuntuNet Alliance, a consortium of National Research and Education Networks (NRENs) runs an exclusive data network for education and research in east and southern Africa. Despite a high degree of route redundancy in ...

Recording university lectures through lecture capture systems is increasingly common. However, a single continuous audio recording is often unhelpful for users, who may wish to navigate quickly to a particular part of a ...

Whether you are interested in improving the usability of Linux, Macintosh or Windows, there is one restriction you cannot escape - the hierarchical file storage system. The notion of files and folders has been with us for ...

This work revolves around the design and evaluation of digital storytelling simulating real personal storytelling. Study One was an ethnography, of real storytellers, which revealed types of narratives, dynamism and ...

This paper describes a survey of 497 final year scholars at schools in the Western Cape, South Africa. They were asked about their inclination to study information systems (IS) or computer science (CS), their knowledge of ...

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 ...

The research has been based on the thesis that efficient volume rendering of datasets, contained on the Internet, can be achieved on average personal workstations. We present a new algorithm here for efficient incremental ...

Computer communication networks are a vital link in providing many of the services that we use daily, and our reliance on these networks is on the increase. The growing use of networks is driving network design towards ...

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 ...

This thesis describes and reflects on the effectiveness of integrating contextmapping as both a methodology and interaction design practice in order to co-­design digital products with and for developing communities. A ...

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 objective of this project was to evaluate the effectiveness of teaching high school students the Java language utilising Java classes. These classes were designed to simplify the syntax of the language and to introduce ...
