A new scalable broadcast algorithm for multiport meshes with minimum communication steps (2003)
Journal Article
Ould-Khaoua, M., Al-Dubai, A., Al-Dubai, A., & Ould-Khaoua, M. (2003). A new scalable broadcast algorithm for multiport meshes with minimum communication steps. Microprocessors and Microsystems, 27(3), 101-113. https://doi.org/10.1016/s0141-9331%2802%2900094-7

Many broadcast algorithms have been proposed for the mesh in the literature. However, most of these algorithms do not exhibit good scalability properties as the network size increases. As a consequence, most existing broadcast algorithms cannot suppo... Read More about A new scalable broadcast algorithm for multiport meshes with minimum communication steps.

Towards a scalable broadcast in wormhole-switched mesh networks (2002)
Presentation / Conference Contribution
Al-Dubai, A. Y., Ould-Khaoua, M., & Mackenzie, L. M. (2002, March). Towards a scalable broadcast in wormhole-switched mesh networks. Presented at 2002 ACM symposium on Applied computing - SAC '02, Madrid, Spain

Broadcast algorithms for wormhole--switched meshes have been widely reported in the literature. However, most of these
algorithms handle broadcast in a sequential manner and do not scale well with the network size. As a consequence, many parallel ap... Read More about Towards a scalable broadcast in wormhole-switched mesh networks.

An Affordance-based Framework for CVE Evaluation (2002)
Presentation / Conference Contribution
Turner, P., & Turner, S. (2002, December). An Affordance-based Framework for CVE Evaluation. Presented at Human computer interaction (Annual conference) 2002, London, England

We argue that a conceptual framework is required to support the
practical evaluation of collaborative virtual environments. We propose
such a framework based on an extended, three level concept of
affordance. The application of the framework is il... Read More about An Affordance-based Framework for CVE Evaluation.

An investigation into virtual representations of real places. (2002)
Presentation / Conference Contribution
Arnspang, J., Benyon, D., Fahle, M., Granum, E., Madsen, C., Pajdla, T., Peleg, S., Smyth, M., Turner, P., Turner, S., & Weinshall, D. (2002, October). An investigation into virtual representations of real places. Presented at Fifth Annual International Workshop on Presence

The paper describes the main themes of a recently funded research project under the European Communitys Future and Emerging Technologies Presence initiative. The aim of the research is to develop new tools for empirical and theoretical studies of pre... Read More about An investigation into virtual representations of real places..

On the design of scalable pipelined broadcasting for mesh networks (2002)
Presentation / Conference Contribution
Al-Dubai, A., & Ould-Khaoua, M. (2002, June). On the design of scalable pipelined broadcasting for mesh networks. Presented at 16th Annual International Symposium on High Performance Computing Systems and Applications, 2002. Proceedings

Minimising the communication latency and achieving considerable scalability are of paramount importance when designing high performance broadcast algorithms. Many algorithms for wormhole-switched meshes have been widely reported in the literature. Ho... Read More about On the design of scalable pipelined broadcasting for mesh networks.

Coded path routing: a new approach to broadcasting in 3-D meshes, Technical Report (2002)
Presentation / Conference Contribution
Al-Dubai, A., & Ould-Khaoua, M. (2001, April). Coded path routing: a new approach to broadcasting in 3-D meshes, Technical Report. Presented at 20th IEEE International Performance, Computing, and Communications Conference, Phoenix, AZ, USA

Broadcast is an important collective communication operation required by many real-world parallel applications. This paper proposes the Coded Path Routing (or CPR for short) as a new approach for designing efficient broadcast algorithms for wormhole-...

An efficient adaptive broadcast algorithm for the mesh network (2001)
Presentation / Conference Contribution
Al-Dubai, A., & Ould-Khaoua, M. (2001, June). An efficient adaptive broadcast algorithm for the mesh network

Most existing broadcast algorithms proposed for the mesh do not scale well with the network size. Furthermore, they have been mainly based on deterministic routing, which cannot exploit the alternative paths provided by mesh topology to reduce commun...

A framework for engineering metaphor at the user interface (2000)
Journal Article
Alty, J., Knott, R., Anderson, B., & Smyth, M. (2000). A framework for engineering metaphor at the user interface. Interacting with Computers, 13(2), 301-322. https://doi.org/10.1016/s0953-5438%2800%2900047-3

Interface metaphors facilitate the learning of new computer systems by supporting the transformation of existing knowledge in order to improve the comprehension of novel situations. However, there is very little guidance for software designers on how... Read More about A framework for engineering metaphor at the user interface.

EniSpace: Evaluating Navigation in Information Space (1999)
Presentation / Conference Contribution
McCall, R., & Benyon, D. (1999, October). EniSpace: Evaluating Navigation in Information Space. Presented at WegNwt 99 World Conference on the WWW and Internet

Traditional methods of evaluating usability such as heuristic evaluation and cognitive walkthrough do not address all issues relating to navigation. This is despite the fact that designing effective navigation within electronic spaces is now consider... Read More about EniSpace: Evaluating Navigation in Information Space.
