Format
The workshop will have morning and afternoon sessions on each of the
two days. The first day and the morning of the second day will
feature a programme of invited lectures and contributed talks. The contributed talks will
be of 15 minutes length and should focus on one of the following topics
within the scope of the three areas listed in the rational for the workshop:
- numerical methods for model reduction and/or bifurcation prediction
- applications which have required model reduction and/or bifurcation prediction
- requirements and availability of open test cases to drive method development
- application requirements for new methods
The purpose of these sessions is to collect together a picture of current
research and future requirements within the workshop theme. The final session
will feature discussions, which are currently envisaged as being on the subjects of numerical methods and test cases. Three potential outcomes are envisaged from these discussions
- A special journal edition will be planned which will collect together a number of papers which show the current status of research. This will be worthwhile to stimulate the exploitation of ideas across traditional boundaries.
- It will be an objective to establish a collection of test cases which would be of use to people developing numerical methods independently of a particular discipline.
- More focussed follow-on events will be identified.
Abstract Submission and Presentation at the Symposium
One page abstracts for contributed talks addressing the themes described above should be sent to Ken Badcock (K.J.Badcock@liverpool.ac.uk) by 29th February, 2008. There will be no proceedings and so written papers are not required.
Presentations will be collected and distributed with the permission of the authors on these web pages after the workshop.
Workshop Fees
Thanks to sponsorship provided by AFRL and European Office of Aerospace Research and Development (EOARD) there will be no workshop fee. Participants will however have to pay for their own accommodation.
