Slowness vector
WebbThus, the slowness vector (to be found) can be presented as a linear combination of two unit-length vectors: the polar axis and the ray velocity directions, with two unknown scalar coefficients. The axial energy propagation is considered as a limit case. WebbFind & Download Free Graphic Resources for Slowness. 36,000+ Vectors, Stock Photos & PSD files.

Finally, there is a “kinetic” formulation, which have proved to be a useful basis for some new numerical techniques. The kinetic model is based on the interpretation that
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 ...
