Forces Induced by Breaking Waves

1970
Chapter VII dealt principally with fluid-induced forces and where the fluid motion appeared in the form of surface gravity waves, only non-breaking waves were considered. In this chapter, our concern is with the forces induced by waves breaking on structures.

Abstract forced symmetry breaking

1996
We consider abstract forced symmetry breaking problems of the type F(x,λ) = y, x ≈ O(x0), λ ≈ λ0, y ≈ O. It is supposed that for all λ the maps F(·,λ) are equivariant with respect to representations of a given compact Lie group, that F(x0, λ0) = 0 and, hence, that F(x,λ0) = 0 for all elements x of the group orbit O(x0) of x0.

Breaking wave forces and velocity fields

Coastal Engineering, 1984
Abstract A new technique for measuring velocities under breaking wave crests using laser-doppler anemometry has been developed. Results may be obtained at positions up to 4 millimeters from the crest. A wave field is presented for a vertically fronted wave and comparison is made with an appropriate numerical study. The velocities obtained are far in

Forced Symmetry Breaking as a Mechanism for Bursting

Physical Review Letters, 1998
A robust mechanism generating regular or irregular bursts of large dynamic range near threshold is described. The mechanism arises in the interaction between oscillatory modes of odd and even parity in systems of large but finite aspect ratio, and provides an explanation for the bursting behavior observed in binary fluid convection by Sullivan and ...

Forced symmetry breaking of homoclinic cycles

Nonlinearity, 1995
In the paper two equivariant equations (model equations for the Rayleigh-Bénard convection and a model for turbulent layers in wall regions with riblets) admitting structurally stable heteroclinic cycles are studied from the point of view of symmetry breaking. Sufficient conditions are formulated for the existence of various type of bifurcations from a

Forced Symmetry Breaking from O(3)

1992
Here we consider the flow near a manifold of equilibria of a specific orbit type of an O(3)-equivariant ordinary differential equation if we break the symmetry of the underlying system. This continues joint work with Mark Roberts [5] on cases of breaking SO(3)-equivariance. Applications to PDE’s are given in [6].

Forced symmetry-breaking in networks with dihedral symmetry

Chaos: An Interdisciplinary Journal of Nonlinear Science
Adaptation in complex systems implies a natural ability to change. In networks, adaptation may include a change in structural connectivity, which can lead to a change in collective behavior. When dihedral symmetry is present, i.e., rotations and reflections of a regular polygon, it is well-known that traveling and standing waves occur, generically, via

A Fifth Force and the Mediation of Supersymmetry Breaking

AIP Conference Proceedings, 2008
In this talk I will discuss a new mechanism for the mediation of supersymmetry breaking [1]. It relies on the existence of a fifth force, or what is more often refer to as a Z′ gauge‐boson. The existence of supersymmetry and an extra gauge‐boson is well motivated by the type of high‐energy theories (GUT models and string constructions) considered in ...

Forced Symmetry Breaking: Theory and Applications

1999
In this paper we want to present some ideas concerning the behavior of equivariant systems under small perturbations of their symmetry. We will touch these questions, discuss some applications and provide references to the literature. These references include details of the mathematical issues as well as further potential applications.

Wind-Forced Shelf Break Upwelling

1983
An analysis of current meter and hydrographic data collected from an array of moorings situated at the shelf break off Nova Scotia is presented. In particular, the focus is on the ocean response to moderate (10 to 20 m s-1), transient winds of two or more days duration blowing parallel to the local bathymetry.
