Large join order optimization on parallel shared-nothing database machines using genetic algorithms (1997)
Presentation / Conference Contribution
Nafjan, K. A., & Kerridge, J. M. (1997, August). Large join order optimization on parallel shared-nothing database machines using genetic algorithms. Presented at Euro-Par'97 Parallel Processing: Third International Euro-Par Conference, Passau, Germany

This paper proposes the use of genetic algorithms (GAs) for optimizing the sequence of large joins execution on parallel shared-nothing database architectures. In order to measure the suitability of this method we compare the GA that we have specific...

User modelling and the design of computer-based assistive devices (1997)
Presentation / Conference Contribution
Keates, S., & Dowland, R. (1997, March). User modelling and the design of computer-based assistive devices. Presented at IEE Colloquium on Computers in the Service of Mankind: Helping the Disabled, London, UK

User models are well represented in the field of human-computer interaction. They afford designers of interfaces detailed quantitative knowledge of the user for improved design, both in terms of the final end-product and the time taken to achieve thi...

Gesture recognition - Research and clinical perspectives. (1997)
Presentation / Conference Contribution
Keates, S., Potter, R., Perricos, C., & Robinson, P. (1997, June). Gesture recognition - Research and clinical perspectives. Presented at RESNA '97 Annual Conference: let's tango : partnering people and technology, Pittsburgh, Pennsylvania

This paper provides an overview of an existing gesture recognition system from both research and clinical perspectives. Developing a gestural input system needs not only a gesture recognizer but also the identification of appropriate clinical conditi...

Supporting cooperative working using shared notebooks. (1997)
Presentation / Conference Contribution
Turner, P., & Turner, S. (1997, September). Supporting cooperative working using shared notebooks

This paper discusses the use of a shared cooperative notebook by a group of software engineers and support staff distributed over two sites. The design: of the notebook is described and results of the pilot trial reported It was found that the system... Read More about Supporting cooperative working using shared notebooks..

Distance estimation in minimal virtual reality environments. (1997)
Presentation / Conference Contribution
Turner, P., & Turner, S. (1997, November). Distance estimation in minimal virtual reality environments

This paper reports on an experimental study into distance estimation in a simple virtual environment. The results have been then compared with an experimental study of spatial cognition in the real world. It is concluded that the minimal virtual envi...

Enhancing community and collaboration in the virtual library. (1997)
Presentation / Conference Contribution
Procter, R., McKinlay, A., Goldenberg, A., Davenport, E., Burnhill, P., & Cannell, S. (1997, September). Enhancing community and collaboration in the virtual library

The advent of the virtual library is usually presented as a welcome development for library users. Unfortunately, the emphasis which is often placed upon convenience of access tends to reinforce the perception of the use of information resources as a...

Using active constructs in user-interfaces to object-oriented databases. (1997)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1997, August). Using active constructs in user-interfaces to object-oriented databases. Presented at In Procs of the 1st International Database engine

This paper examines the use of active constructs in the definition of user-interfaces to object-oriented databases. A development environment for user-interfaces to databases is presented which features the interactive use of active features of an ob...

The perspective tunnel: An inside view on smoothly integrating detail and context. (1997)
Presentation / Conference Contribution
Mitchell, K., & Kennedy, J. (1997, April). The perspective tunnel: An inside view on smoothly integrating detail and context. Presented at Proc. of Eurographics Workshop on Visualisation in Scientific Computing

The perspective tunnel, a general kind of information visualisation artefact, embodies a visual form which exploits natural human visual perception. Perspective tunnels map information on to the floor, ceiling and walls of a tunnel, so that both ever...

Representing temporal relationships between events and their effects. (1997)
Presentation / Conference Contribution
Ma, J., Knight, B., & Peng, T. (1997, May). Representing temporal relationships between events and their effects. Presented at 4th Workshop on Temporal Representation and Reasoning

Temporal relationships between events and their effects
are complex. As the ejjects of a given event, a
proposition may change its truth value immediately after
the occurrence of the event and remain true until some
other events occur, while anot... Read More about Representing temporal relationships between events and their effects..

Formal methods for the re-engineering of computing systems. (1997)
Presentation / Conference Contribution
Liu, X., Yang, H., & Zedan, H. (1997, August). Formal methods for the re-engineering of computing systems

This paper presents a short review of formal methods and their use in the re-engineering of computing systems. Five classes of formal notations and theories, namely state/model-based, logic-based, algebraic-based, process algebra and net-based formal...
