ADDITIONAL INFORMATION 
The LAMEF is considered as a " pôle d'excellence "  (a center of excellency) by the French DRET
(Direction of Research, Studies and Techniques) in the field of fatigue.
It participates in numerous european programs : BRITE EURAM, SOCRATES, TEMPUS, COMETT
High Schools Conference (Cooperation with UK, Poland, Greece, Portugal, Spain, Israël and Russia) ;
and also in  a national program : INTER-REGIONS program : Aquitaine/Spain.
