We consider vortex filament systems which is regarded as a three dimensional extension of the point vortex system introduced by Onsager to investigate the 2D turbulence. We show that this system is equipped with a dual variational structure as in the case of the point vortex system, and that the mean field equations for the system in terms of the stream function and the vorticity are derived from a Lagrangian. In addition, we discuss the existence of solutions to the mean field equations.

The Oliver and Pharr method is the prevailing process for thin films Young's modulus evaluation. Introduced initially for homogeneous materials, this method does not account for the substrate and can consequently lead to significant error, especially at large indentation depths. We suggest here possible methods to improve the accuracy by making use of inverse analysis and finite element computations of the one layer elastic indentation problem.
