Ce travail porte sur l'équation de Reynolds comportant 3 facteurs d'écoulement, définis sur un élément de surface, caractérisant les effets induits par les rugosités. Les facteurs de frottement sont aussi abordés. Une br...

We present a graph-based decision procedure for Gödel-Dummett logics and an algorithm to compute counter-models. A formula is transformed into a conditional bi-colored graph in which we detect some specific cycles and al...

We investigate the asymptotic behavior, as ε tends to 0+, of the transverse displacement of a Kirchhoff-Love plate composed of two domains Ωε+∪ Ωε-, contained in the (x1,x2)-coordinate plane and depending on ε in the fol...

The objective of this work is to extend the linear analysis of PulsedDigitalOscillators to those topologies having a Finite Impulse Response (FIR) in the feedback loop of the circuit. It will be shown with two specific e...
