We study the existence of time quasi-periodic vortex patches for Euler and quasi-geostrophic shallow-water (QGSW) equations which are bidimensional nonlinear and nonlocal transport-type fluid models. Vortex patches are weak solutions in the Yudovich

Study and realization of polymer-based photonic crystals: Application to nonlinear and quantum optics

Autor: Lai, Ngoc Diep

Publikováno v: Optique [physics.optics]. Ecole Normale Supérieure de Cachan, 2013

We have investigated the optical properties of polymer-based photonic crystals and photonic quasicrystals. We have demonstrated a great interest of using quasi-periodic structures to obtain an isotropic photonic bandgap, with material possessing low

Poéticité de la description au dix-neuvième siècle : (the various ways nineteenth-century French poets and novelists write descriptions of feelings, events, and things)

Autor: Ippolito, Christophe

Much maligned throughout the entirety of the 19th century, description generates definitions which are likewise normative mechanisms. This study seeks to demonstrate how the writer makes use of descriptive prohibitions while simultaneously defying th
