Large join order optimization on parallel shared-nothing database machines using genetic algorithms (1997)
Presentation / Conference Contribution
Nafjan, K. A., & Kerridge, J. M. (1997). Large join order optimization on parallel shared-nothing database machines using genetic algorithms. In Euro-Par'97 Parallel Processing: Third International Euro-Par Conference Passau, Germany, August 26–29, 199

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...

Supporting cooperative working using shared notebooks. (1997)
Presentation / Conference Contribution
Turner, P., & Turner, S. (1997). Supporting cooperative working using shared notebooks. In Proceedings of the fifth conference on European Conference on Computer-Supported Cooperative Work (281-295)

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). Distance estimation in minimal virtual reality environments. In Proceedings of the 4th UK VR-SIG Conference

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). Enhancing community and collaboration in the virtual library. In Research and Advanced Technology for Digital Libraries (25-40). https://doi.org/10.1007/BFb0026

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). Using active constructs in user-interfaces to object-oriented databases. In Proceedings [of the First] International database engineering and applications symposium, (3-12)

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). The perspective tunnel: An inside view on smoothly integrating detail and context. In W. Lefer, & M. Grave (Eds.), Visualization in scientific computing '97: proceedings of the Eurographics Workshop in Boulogne-sur-Mer,

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). Representing temporal relationships between events and their effects. In Proc. of the 4th Workshop on Temporal Representation and Reasoning (148-152). https://doi.org/10.1109/TIME.1997.600796

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...

Formal methods for the re-engineering of computing systems. (1997)
Presentation / Conference Contribution
Liu, X., Yang, H., & Zedan, H. (1997). Formal methods for the re-engineering of computing systems. In COMPSAC '97-21st International Computer Software and Applications Conference (409-414). https://doi.org/10.1109/CMPSAC.1997.625024

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...

A design framework for system re-engineering. (1997)
Presentation / Conference Contribution
Liu, X., Chen, Z., Yang, H., Zedan, H., & Chu, W. (1997). A design framework for system re-engineering. In APSEC'97/ICSC'97 - Fourth Asia-Pacific Software Engineering and International Computer Science Conference (342-352). https://doi.org/10.1109/APSEC.

We discuss the current situation of formal methods and their use in the re-engineering of computing systems, especially real time systems. Based on the analysis result, a solution which uses a consistent 4-sector Wide Spectrum Language (WSL) is propo... Read More about A design framework for system re-engineering..
