Automatic tracking of faults by slope decomposition


Method for locating fault lines or surfaces in 2-d or 3-d seismic data based on the fact that fault discontinuities in the space domain span a wide range in a local slowness (slope) domain, whereas other dipping events in the space domain data, such as noise, tend to be coherent, and hence will appear focused in the slowness dimension.

Systems and methods for determining optimal parameters for dynamic quantum clustering analyses


In the present work, quantum clustering is extended to provide a dynamical approach for data clustering using a time-dependent schrödinger equation. To expedite computations, we can approximate the time-dependent hamiltonian formalism by a truncated calculation within a set of gaussian wave-functions (coherent states) centered around the original points.
