Dynamics of Love-Type Waves in Orthotropic Layer Under the Influence of Heterogeneity and Corrugation
The present problem deals with the propagation of Love-type surface waves in a bedded structure comprises of an inhomogeneous orthotropic layer and an elastic half-space. The upper boundary and the interface between two media are considered to be corrugated. An analytical method (separation of variables) is adapted to solve the second order PDEs, which governs the equations of motion. Equations...
متن کاملLateral Heterogeneity and Azimuthal Anisotropy of the Upper Mantle: Love and Rayleigh Waves 100-250 s
The lateral heterogeneity and apparent anisotropy of the upper mantle are studied by measuring Rayleigh and Love wave phase velocities in the period range 100-250 s. Spherical harmonic descriptions of the lateral heterogeneity are obtained for order and degree up to 1 = m = 10. Slow regions are evident at the East Pacific Rise, northeast Africa, Tibet, Tasman Sea, southwestern North America, an...
متن کاملThe rotation of polarization by gravitational waves
There are conflicting statements in the literature about the gravitational Faraday rotation of the plane of polarization of polarized electromagnetic radiation travelling through a gravitational wave. This issue is reconsidered using a simple formalism describing the rotation of the plane of polarization in a gravitational field, in the geometric optics approximation. It is shown that, to first...
متن کاملInvestigating the Amount of Forces Caused by Solitary Waves on Coastal Walls Using OpenFOAM Software
Coastal walls (dyke) are one of the methods of protecting the coast against coastal erosion and destructive forces of waves. The purpose of this study is to simulate the wave collision with the coastal dyke and compare the results with the laboratory model. Open FOAM open source software and K-ω SST turbulence model were used to simulate the amount of wave consumed by the coastal dyke. Taking i...
متن کاملThe three-sided romance of the lateral line: glia love axons love precursors love glia.
The lateral line system of fish and amphibians is closely related to the inner ear in terms of evolution, morphology and physiology. Several recent papers have shed new light on the postembryonic development of this system, and have revealed an unexpected triangular relationship where migrating sensory precursors guide axons, axons guide glia and glia, in turn, control the formation of sensory ...
