Webb5 dec. 2002 · The slowness vector u points into the direction of wave propagation, and its modulus is the reciprocal of the wave speed. The ray parameter p and the horizontal … Webb16 sep. 2024 · Similarly, the quantity in the numerator of this slowness vector provides a new direction vector which points in the PVD, and we thus refer to it as the direction vector for the PVD. This new direction vector provides a convenient way to directly compute the PVD by using the extrapolated vector wavefields in general anisotropic media.

Webb13 apr. 2024 · After obtaining the slowness vector, the ray velocity can be computed easily. A 2D model is designed to test the feasibility of the new methods. Using the results for … Webb28 juni 2024 · This phase velocity defines a complex slowness vector, which is used to calculate the polarisation of the Rayleigh wave at different depths in an elastic half-space. Effects of prestress and anisotropic symmetry on the phase velocity of the Rayleigh wave and associated particle motion are analysed by a numerical example. Webbslowness vectors of all bootstrap samples are gathered and the clustering algorithm DBSCAN (Density-Based Spatial Clustering of Applications with Noise) is used to identify arrivals as clusters of slowness vectors. The mean of each cluster gives the slowness vector measurement for that arrival and the distribution of slowness vectors in each ... how to open geforce menu
