Invariant frames for vector bundles and applications

Tudor Ratiu, Madeleine Jotz

This paper completes a proof of the Dirac reduction theorem by involutive tangent subbundles. As a consequence, Dirac reduction by a proper Lie group action having one isotropy type is carried out. The main technical tool in the proof is the notion of part ...

Role of elastin anisotropy in structural strain energy functions of arterial tissue

Nikolaos Stergiopoulos

The vascular wall exhibits nonlinear anisotropic mechanical properties. The identification of a strain energy function (SEF) is the preferred method to describe its complex nonlinear elastic properties. Earlier constituent-based SEF models, where elastin i ...

Method for fabricating micromirror for barcode reader, involves forming holes having diameter less than width of arms on both side of micromirror and wafer and on edges of region separating wafer and micromirror by etching arms

Philippe Renaud, Nicolas Abelé

A method for fabricating a micromirror in a wafer, including the steps of: depositing and etching layers forming two arms; etching the wafer such that in the back face only a thin portion of the wafer remains in the region of formation of the micromirror a ...

Biomechanics of Vascular Wall : the Role of Structural Organization of Elastin and Collagen

This thesis contributes to the field of biomechanics of vascular wall. The focus is particularly on the microstructure of vascular elastin and collagen constituents and their contribution to the macroscopic mechanical behavior of the wall. The analysis is ...
