[1] Microwave and acoustic systems operated in the large wind-wave tank in Luminy, Marseille, France, show that most small-scale waves produced at large angles to the wind are products of breaking events bound to longer waves in the tank. These longer waves propagate at the dominant wave phase speed for fetches near 7 m but travel at speeds corresponding to the phase speed of a wave half as lon...

ENO (essentially nonoscillatory) and weighted ENO (WENO) schemes were designed for high resolution of discontinuities, such as shock waves, while optimized schemes such as the DRP (dispersion–relation–preserving) schemes were optimized for short waves (with respect to the grid spacing 1x , e.g., waves that are 6–81x in wavelength) in the wavenumber space. In this paper, we seek to unite the adv...

We study efficient injectors for coupling light from z-invariant ridge waveguides into slow Bloch modes of single-row defect photonic crystal waveguides. Two-dimensional vectorial computations performed with a Bloch mode theory approach predict that very high efficiencies (>90%) can be achieved for injector lengths of only a few wavelengths in length, even for small group velocities in the rang...

The phase velocities of Rayleigh waves increase more rapidly with distance from the East Pacific Rise (EPR) axis than is predicted by models of conductive cooling of the lithosphere. Low velocities near the axis are probably caused by partial melt at depths of 20 to 70 kilometers in a zone several hundred kilometers wide. The lowest velocities are offset to the west of the EPR. Wave propagation...

  Objective: Alveolar ridge preservation in patients with inadequate bone volume is one treatment option for successful implant placement and can be done by using bone graft materials. On the other hand, Ceno Bone has been recently produced by Hamanand Saz Baft Kish Co. as a bone bioimplant of allograft origin. This study aimed to assess the clinical, histologic and histomorphometric results of...

3D seismic reflection data have been used to map 784 enigmatic ridge-furrow structures in water depths of 0.8–1.7 km offshore Angola. The are characterised by asymmetric ridges with intervening furrows, typically <0.5–5.5 long, a sinuous bifurcating planform. furrows well-imaged on profiles, and range from 60 80 m width, up 10 amplitude, 0.1–1 wavelength. furrow sets aggrade downslope direction...

Numerical simulations are conducted of geostrophically balanced flow over an isolated mountain cut by a horizontal gap. The relative importance of the along-gap synoptic-scale pressure gradient and terraininduced mesoscale circulations for the generation of gap winds was examined by changing the direction of the synoptic-scale wind relative to the topography. In all cases, the forcing associate...

Profiles of potential density obtained from CTD casts at two stations at different distances from the Hawaiian ridge are examined for evidence of diapycnal turbulent mixing as indicated by density inversions and internalwave vertical strain. Results from independent casts are used to produce ensemble-averaged vertical distributions for the number of inversions and the Thorpe scale. Both paramet...

Abstract In this study, we consider particle-laden flows on an inclined plane under the effect of gravity. Previous experimental works have noted that a particle-rich ridge is generated near contact line. We investigate bump structure observed in ridges terms Lax’s shock waves mathematical theory conservation laws, explicitly considering particles with nontrivial radii morphology flows. also ex...
