Rayleigh waves soil stiffness shear wave profiles shallow geophysics shear modulus
2015/9/29
The dispersive nature of Rayleigh waves is the basis of many identification procedures to infer the site stiffness profile from surface measurements. This article presents some important aspects relat...
Consider a viscous fluid of finite depth below the air. In the absence of the surface tension effect at the air-fluid interface, the long time behavior of a free surface with small amplitude has been ...
We consider the quantum radiation of scalar particles from a surface wave excited on a plane surface of a mirror. It is assumed that the field obeys Dirichlet condition on the boundary of the mirror. ...
Searching for chaotic deterministic features in laboratory water surface waves
chaotic deterministic features water surface waves
2009/11/12
The dynamic evolution of laboratory water surface waves has been studied within the framework of dynamical systems with the aim to identify stochastic or deterministic nonlinear features. Three differ...

2009/9/4
Nonlinear magnetostatic surface wave in a slab waveguide structure has been investigated. The design consisted of dielectric film between two thick nonlinear nonmagnetic negative permittivity material...
QR-Factors in the Crystalline Uppermost Crust in Finland from Rayleigh Surface Waves
Q Rayleigh waves Upper Crust Finland
2009/6/10
During the period 1981-1993 five deep seismic sounding profiles were performed in Finland as
an international co-operation to study the crustal structure of the Fennoscandian Shield. Apart from Pand ...
On the Interaction Between Long and Short Surface Waves
Short Surface Waves Interaction Long Surface Waves
2009/3/7
Short, dissipative, surface waves superposed on longer waves cause a growth of the long wave momentum Ml at a rate where kl, al are the amplitude and wavenumber of the long waves, so that klal is thei...
Measurement of the High-Frequency Spectrum of Ocean Surface Waves
High-Frequency Spectrum Ocean Surface Waves
2009/3/7
High-frequency spectra of wind-generated ocean waves were measured at an ocean research tower of Kyushu University using a fast-response wave recorder and an electronic differentiating circuit. Wind w...
Daylight Imagery of Ocean Surface Waves for Wave Spectra
surface-reflected daylight Ocean Surface Waves upwelling light Wave Spectra
2009/2/9
Both surface-reflected daylight and upwelling light are modeled to second order to help provide a quantitative and physically interpretable description of daylight imagery of ocean surface waves for w...
The Horizontal Diffusion of Tracers by Surface Waves
Horizontal Diffusion Tracers Surface Waves
2009/2/7
The horizontal dispersion of tracers in the presence of a random field of ocean surface waves is examined. Random fluctuations in the local Stokes-drift current cause a water particle to follow a rand...
Storm-Generated Surface Waves and Sediment Resuspension in the East China and Yellow Seas
