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 ...

Modern radio interferometer arrays are powerful tools for obtaining high resolution images of low frequency electromagnetic radiation signals in deep space. While single dish radio telescopes convert the electromagnetic ...

Various campaigns indicate that a need exists for a convenient and anonymous crime reporting framework for the context of the developing world. In this thesis a contribution is made by means of a framework that facilitates ...

Conditional Access (CA) is widely used by pay-television operators to restrict access to content to authorised subscribers. Commercial CA solutions are available for structured broadcast and Internet Protocol Television ...

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 ...

South Africa has one of the highest Human Immunodeficiency Virus (HIV) prevalence rates in the world. People living with HIV/AIDS experience many unrelieved symptoms. Nutritional care and support are important in preventing ...

In this thesis, a systematic study of the structural characterization of the capsular polysaccharides of Streptococcus pneumoniae is conducted using Molecular Modelling methods. S.pneumoniae causes invasive pneumococcal ...

The digital Bleek and Lloyd Collection is a rare collection that contains artwork, notebooks and dictionaries of the earliest habitants of Southern Africa. Previous attempts have been made to recognize the complex text in ...

The closure of the European airspace due to the eruption of the Icelandic volcano Eyjafjallajokull in 2010 proved a major challenge for airlines and aviation authorities on a global scale. In contrast, more seasonal adverse ...

The design of Digital Library Systems (DLSes) has evolved overtime, both in sophistication and complexity, to complement the complex nature and sheer size of digital content being curated. However, there is also a growing ...

A first half of a first course on how to program in Python. This set of six files comprises the slides from first 6 weeks of our 12 week first year course on Python Programming. It is an introduction aimed at students who ...

The growth of mobile computing is changing the way people communicate. Mobile devices, especially mobile phones, have become cheaper and more powerful, and are able to run more applications and provide networking services. ...

Data discovery and data handling often presents serious challenges to organizations that manage huge archives of raster datasets such as those generated by satellite remote sensing. Satellite remote sensing produces a ...

Analysis of storage system workloads is important for a number of reasons. The analysis might be performed to understand the usage patterns of existing storage systems. It is very important for the architects to understand ...

This dissertation explores the use of a simple model of the human visual system to yield a performance improvement with hierarchical radiosity. Hierarchical radiosity is a physically based rendering algorithm and hence ...

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 ...

ATM and dynamic reconfiguration allow for rapid changes in a virtual path network depending on traffic load and future demands. This technology improves the utilisation, lowers the call blocking probability and increases ...

Peer-to-peer or P2P systems are applications that allow a network of peers to share resources in a scalable and efficient manner. My research is concerned with the use of P2P systems for sharing databases. To allow data ...
