Indigenous Knowledge Management Systems are being developed in order to preserve, process and retrieve knowledge. Unfortunately, most of the systems available do not take into account the different cultural ways of organising ...

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 ...

The rise in global connectivity driven by user-demand is bringing about a wave of end-user interconnectivity applications. This, coupled with the improvements in software security that have forced a shift from syntactic ...

This dissertation seeks to develop image based animation methods using the technique of optic flow analysis developed for a moving planar object. Image based rendering is presented as a class of algorithm using two dimensional ...

A tool has been designed and implemented to use information extracted from photographs captured using uncalibrated cameras (so-called casual photographs) to fill the occlusions which occur in three-dimensional models of ...

Multi-dimensional security protocol engineering is effective for creating cryptographic protocols since it encompasses a variety of design, analysis and deployment techniques, thereby providing a higher level of confidence ...

Currently, the standard approach to visibility preprocessing algorithms is to use a form of approximate solution, known as conservative culling. Such algorithms over-estimate the set of visible polygons. This compromise ...

Cosmological simulations are used by astronomers to investigate large scale structure formation and galaxy evolution. Structure finding, that is, the discovery of gravitationally-bound objects such as dark matter halos, ...

Marsaglia and Maclaren combined two linear congruential generators in order to produce a pseudo random number sequence uniformly distributed in the range [0,2³⁵]. Their method is a considerable improvement compared with ...

The authoring of realistic terrain models is necessary to generate immersive virtual environments for computer games and film visual effects. However, creating these landscapes is difficult - it usually involves an artist ...

The development of algorithms to efficiently determine an optimal path through a complex environment is a continuing area of research within Computer Science. When such environments can be represented as a graph, established ...

The DISTRIX operating system is a multiprocessor distributed operating system based on UNIX. It consists of a number of satellite processors connected to central servers. The system is derived from the MINIX operating ...

The increasing number of people having access to computers and the Internet and the numerous services provided by the Internet - e.g., Internet banking, online shopping, eBay, email - emphasizes the need for computer ...

Software engineering is a discipline concerned with manufacturing or developing software. Software plays a pivotal role in everyday life, an absence of which will be devastating to a number of governmental, recreational ...

A graphical language is developed as a generalization of the structured flowcharts proposed by Nessi and Shneiderman. This language can be used in the specification of procedures, procedure interfaces and data structures. ...

Modern Molecular Dynamics force fields, such as the CHARMM36 and GLYCAM06carbohydrate force fields, are parametrised to reproduce behaviours for specific molecules under specific conditions in order to be able to predict ...

Myasthenia gravis (MG) is an autoimmune disorder in which auto-antibodies directed at the acetylcholine receptors (AChR) of the neuromuscular junction (NMJ) block, alter or destroy their targets. The anti-AChR antibodies ...

There has been great interest in realising the Semantic Web. Ontologies are used to define Semantic Web applications. Ontologies have grown to be large and complex to the point where it causes cognitive overload for humans, ...

A relatively new area of study that first received attention during the past decade explores how spatiotemporal data can be efficiently used in applications and stored in databases. Spatial data includes the locations or ...

This study aims at investigating a framework that utilises the latest advances in KMS technology. This research outlines the framework and describes a system developed around this. The framework is based on fundamental ...
