"In this thesis, a cell traction force microscopy method is developed for measuring traction forces of connective tissue cells. This method includes an improved methodology in traction force microscopy of live cells cultured on an elastic substrate.

La mise en forme à froid est étudiée à travers des essais de traction in situ et des prélèvements d’échantillons de traction plane et de gonflement. L’amorçage est lié à la rupture des particules ou de l’interface particule/matrice. Les porosités croissent par déformation plastique de la matrice. Cette croissance est favorisée par les états de contraintes triaxiaux. L’anis

Abstract:
Ce travail de thèse a pour but l'optimisation de forme en forgeage 3D. Les problèmes à résoudre consistent à chercher la forme optimale du lopin initial ou des outils de préforme afin de minimiser une fonction coût F qui représente une mesure de non-qualité définie par les industriels. Ce sont souvent des problèmes multi optima, et le temps nécessaire pour une évaluation de la fonction coût est très élevé (de l'ordre de la journée). L'objectif de cette thèse est de construire un module d'optimisation automatique qui permet de localiser l'extremum global à un coût raisonnable (moins de 50 calcu

Abstract:
As the core of virtually all vocal and instrumental composition in the Baroque music, the basso continuo group had an extremely important role in the sacred cantatas by Johann Sebastian Bach (1685-1750). During the Baroque period, the choice of instruments was sometimes indicated by the composer, but frequently the performers had to determine which instruments were most appropriate for the particular environment and context of the music.When performing the sacred cantatas of J.S. Bach, the conductor must identify and make decisions regarding the choices and combinations of instruments for bot
