Proceedings of the 5th METTI School

The Eurotherm Advanced Spring School “Thermal Measurements and Inverse Techniques" has been run by the METTI Group (Mesures en Thermiques et Techniques Inverses) which constitutes a division of the Société Française de Thermique (French Heat Transfer Society).
It was supported by CNRS, Université de Bretagne Sud and Université Européenne de Bretagne.

The METTI group has already run or co-organized four similar schools, in the Alps (Aussois) in 1995 and 2005, in the Pyrenees (Bolquère-Odeillo) in 1999 and in Rio de Janeiro, in cooperation with ABCM, Brazilian Society of Mechanical Engineering and Sciences, in November 2009.

For this fifth edition, which took place in Roscoff (Brittany, France), June 13-18, 2011, the school was again open to participants from the European Community with the support of the Eurotherm Committee. It gathered 75 attendees from 10 different countries, with one third of doctoral students.

This school, which was organized around modern generic methods of experimental design and inversion in heat transfer, is a consequence of the Eurotherm 68 seminar “Inverse Problems and Experimental Design” (Poitiers 2001) where participants felt the need for an up-to-date formation in these fields. It is also related to the cycles of “International Conference in Inverse Problems: Theory and Practice” and “Inverse Problems, Design and Optimization” (next IPDO Conference in Albi, France, June 26-28, 2013, see http://ipdo2013.congres-scientifique.com/).

Techniques for solving inverse problems as well as their applications are currently rapidly developing in all the different domains of physical sciences and particularly in heat transfer, applied mathematics, statistics, signal processing, etc.

Experimentalists desiring to go beyond traditional data processing techniques for estimating the parameters of a model with the maximum accuracy feel often ill-prepared in front of inverse techniques.

In order to avoid biases at different levels of this kind of involved task, it seems compulsory that specialists of measurement inversion techniques, modelling techniques and experimental techniques share a wide common culture and language. These exchanges are necessary to take into account the difficulties associated to all these fields. It is in this state of mind that this advanced school has been prepared.

Two books were distributed at the beginning of the school. Most of the corresponding files (texts and presentations), which have been revised with some modifications, can be freely downloaded now (see the Table below).
