TRANSFORMATION OF REGULAR WAVES.

Proceedings of the Institution of Civil Engineers, 1987
Results are presented from calculations for shoaling waves using a development of Dean's non-linear stream function which display better agreement with previous experimental data for parallel waves in shallow water than other currently available theories. The results are presented in a manner suitable for design applications. In addition to wave height

Response of Modelled Ice Masses to Regular Waves and Regular Wave Groups

Proceedings OCEANS '83, 1983
An experimental investigation to determine the maximum instantaneous velocities attainable by a range of ice masses in regular waves and regular wave groups has been conducted. Models constructed of paraffin wax were shown to attain velocities approximately equal to those of the particle velocities in regular waves, for model beam to wavelength ratios ...

Waves and Patterns on Regular Graphs

SIAM Journal on Applied Dynamical Systems, 2015
The authors consider coupled phase oscillators on finite regular networks that can be thought of as approximating the surface of a sphere. Examples studied include the dodecahedron (20 nodes) and the buckyball (60 nodes) and various generalisations of these. For some networks and some coupling functions the authors can show that rotating wave solutions

Regularity Results for Nonlinear Wave Equations

The Annals of Mathematics, 1993
We report on some recent progress on the Cauchy problem for semilinear wave equations \(u_{tt} - \Delta u + g(u) = 0\) in \(\mathbb{R}^n \times \mathbb{R}\) for smooth nonlinearities \(g\) of critical growth \(g(u) = u |u |^{2^* - 2}\) for large \(|u |\), where \(2^* = (2n)/(n - 2)\), and related problems. Our aim in this article is twofold.

Travelling Wave Solutions of the General Regularized Long Wave Equation

Qualitative Theory of Dynamical Systems, 2021
This paper studies the model of the general regularized long wave (GRLW) equation. The main contribution of this paper is to find that GRLW equation has extra kink and anti-kink wave solutions when $p = 2n + 1$, while it's not for $p = 2n$. The authors give the phase diagram and obtained possible exact explicit parametric representation of the ...

Scattering of regularized-long-wave solitary waves

Physica D: Nonlinear Phenomena, 1984
The Lagrangian density for the regularized-long-wave equation (also known as the BBM equation) is presented. Using the trial function technique, ordinary differential equations that describe the time dependence of the position of the peaks, amplitudes, and widths for the collision of two solitary waves are obtained.
