Anomalous resonance phenomena of solitary waves with internal modes [PDF]
, 1999 We investigate the non-parametric, pure ac driven dynamics of nonlinear Klein-Gordon solitary waves having an internal mode of frequency $\Omega_i$. We show that the strongest resonance arises when the driving frequency $\delta=\Omega_i/2$, whereas when $

Asymptotic models for the generation of internal waves by a moving ship, and the dead-water phenomenon [PDF]
, 2011 This paper deals with the dead-water phenomenon, which occurs when a ship sails in a stratified fluid, and experiences an important drag due to waves below the surface.

Internal solitary wave transformation over the slope: Asymptotic theory and numerical simulation
Journal of Ocean Engineering and Science, 2018 The propagation and evolution of long nonlinear internal solitary waves over slope-shelf topography is theoretically and numerically studied in a two-layer fluid system of finite depth. The variable Korteweg–de Vries (vKdV) and variable extended Korteweg–

Brief communication: Modulation instability of internal waves in a smoothly stratified shallow fluid with a constant buoyancy frequency [PDF]
Natural Hazards and Earth System Sciences, 2019 Unexpectedly large displacements in the interior of the oceans are studied through the dynamics of packets of internal waves, where the evolution of these displacements is governed by the nonlinear Schrödinger equation.

Examining Breaking Internal Waves on a Shelf Slope Using Numerical Simulations [PDF]
Oceanography, 2012 The subject of internal waves interacting with bottom topographic features in the ocean has received much attention in the past few decades. This heightened interest is mainly due to a conjecture that breaking internal waves at boundaries can be a ...

Strongly nonlinear, simple internal waves in continuously-stratified, shallow fluids [PDF]
Nonlinear Processes in Geophysics, 2011 Strongly nonlinear internal waves in a layer with arbitrary stratification are considered in the hydrostatic approximation. It is shown that "simple waves" having a variable vertical structure can emerge from a wide class of initial conditions.

Nonlinear waves in solids with slow dynamics: an internal-variable model [PDF]
, 2017 In heterogeneous solids such as rocks and concrete, the speed of sound diminishes with the strain amplitude of a dynamic loading (softening). This decrease known as "slow dynamics" occurs at time scales larger than the period of the forcing.
