THE PROBLEM OF SCATTERING BY A MIXTURE OF CRACKS AND OBSTACLES

The Problem of Scattering by a Mixture of Cracks and Obstacles

Consider the scattering of an electromagnetic san jose sharks trucker hat time-harmonic plane wave by an infinite cylinder having an open crack and a bounded domain in as cross section.We assume that the crack is divided into two parts, and one of the two parts is (possibly) coated on one insulated debakey side by a material with surface impedance.

Lyapunov analysis of data-driven models of high dimensional dynamics using reservoir computing: Lorenz-96 system and fluid flow

We computed the Lyapunov spectrum and finite-time pitchy delight onee stick Lyapunov exponents of a data-driven model constructed using reservoir computing.This analysis was performed for two dynamics that exhibit a highly dimensionally unstable structure.We focused on the reconstruction of heterochaotic dynamics, which are characterized by the coe
