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 ...

In this dissertation we explore methods of quality control of untextured polygonal models. The tools presented build, evaluate and improve on the field of multiresolution analysis through decimation. We evaluate the quality ...

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 ...

Since the emergence of the digital computer in the 1940s, computer architecture has been largely dictated by the requirements of mathematicians and scientists. Trends have thus been towards processing data as quickly and ...

Datalog is the fusion of Prolog and Database technologies aimed at producing an efficient, logic-based, declarative language for databases. This fusion takes the best of logic programming for the syntax of Datalog, and the ...

This study investigates the modelling of adative routing algorithms with specific reference to the algorithm of an existing Wide Area Network (WAN). Packets in the network are routed at each node on the basis of routing ...

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 ...

Rita+ is a structured syntax directed document processing system, which allows users to edit documents interactively, and display these documents in a manner determined by the user. The system is SGML (Standard Generalized ...

The design of efficient, reliable communication protocols has long been an area of active research in computer science and engineering, and will remain so while the technology continues to evolve, and information becomes ...

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 ...

The efficiency of an image compression/synthesis system based on a spline multi-resolution analysis (MRA) is investigated. The proposed system uses a quadratic spline wavelet transform combined with minimum-mean squared ...

There has been much research in the area of visual query systems in recent years. This has stemmed from the need for a more powerful database visualization and querying ability. In addition, there has been a pressing need ...

This dissertation concerns. analytical methods for assessing the performance of concurrent systems. More specifically, it focuses on the efficient generation and solution of large Markov chains which are derived from models ...

In this thesis, the performance analysis of SDL with a new type of stochastic Petri net is described. This new net is called SDL-net. The Concurrent Communicating System is described, and the need for qualitative and ...

Intermediaries are necessary to overcome challenges of Internet use for many users in the developing world. However the need for co-presence with intermediaries can be inconvenient for beneficiaries, and the process is ...

This thesis work takes an investigative approach into developing a middleware solution for managing services in a community cloud computing infrastructure pre-dominantly made of interconnected low power wireless devices. ...

The Weighted Histogram Analysis Method (WHAM) is a technique used to calculate free energy from molecular simulation data. WHAM recombines biased distributions of samples from multiple Umbrella Sampling simulations to yield ...

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 ...

ICT has furthered the social and economic development of societies but, rural African communities have lagged behind due to issues such as sparse population, low household income, a lack of electricity and other basic ...
