INTERNATIONAL WORKSHOP

Multi-scaled Modelling in Defence Research and its Spin-offs

Held at LIMS during 31st May – 1st June 2007

TOPICS


The mathematical modelling explored in detail at the workshop concerned three areas
• biomedical /human-risk-interface [Brain under severe stress; nonlinear network analyses; location and perception problems; fire spread]
• terrain /geophysical problems [Sand-dune movement, effect on local terrain, geophysical analyses]
• impact /multi-particle problems [Cratering; droplet breakup methodology applied to fracture, aerosols; shaped-charge analysis, coats, detonics, fragmentation; oil-well perforation; ice impacts],
and other spin-offs, e.g. unmanned vehicles, drought or unrest instabilities, new methodologies. The applications all arose in the Defence context and its spin-offs, covering a very wide area.

PROGRAMME

The form of the workshop was as follows.


• Days One and Two had talks for the whole group on the three defined areas. A listing of the talks is given at the end of this section.
• These talks were interspersed during Day One and the first half of Day Two with breakout sessions for detailed discussions of topics within the three areas or topics spanning the areas.
• The event finished at the end of Day Two with wrap-up sessions and reports on the specific topics, future proposals and other allied developments.
• A dinner cruise was also held in the evening of 31st May on a boat on the Thames, which allowed much extra networking and discussions.
Major support for the workshop was from EPSRC (Engineering and Physical Sciences Research Council, UK) and EOARD (European Office of Aerospace Research and Development, Air Force Office of Scientific Research, USA). The event was also supported by LIMS, the Department of Mathematics UCL, the MAPS Faculty UCL and Arizona State University.
The workshop committee comprised Frank Smith, Nick Ovenden as leaders aided by Malcolm Arthur, Robert Bowles, Steve Bishop, Doug Cochran, John Curtis, Mick Davey, Ian Eames, Fariba Fahroo, Ian Ford, Roger Gent, Julian Hunt, Ted Johnson, Peter Muller, Sergei Timoshin.
