Uni-directional waves over slowly varying bottom. Part I: Derivation of a KdV-type of equation
TL;DR: In this paper, the exact equations for surface waves over an uneven bottom can be formulated as a Hamiltonian system, with the total energy of the fluid as Hamiltonian, and the surface elevation is described by a forced KdV-type of equation.

A finite element scheme to study the nonlinear optical response of a finite grating without and with defect
TL;DR: In this paper, a simple numerical scheme based on the finite element method (FEM) using transparent-influx boundary conditions to study the nonlinear optical response of a finite one-dimensional grating with Kerr medium was presented.

Existence of multiple normal mode trajectories on convex energy surfaces of even, classical Hamiltonian systems
TL;DR: In this article, the number of distinct trajectories which correspond to particular periodic solutions (normal modes) with the same energy is investigated, and a constrained dual action principle is introduced. And the results show that the existence of at least n distinct trajectory if specific conditions are satisfied.
