In such cases, the 2D geometry provides the minimal array configuration required for evaluating the dominant AN events present in the study area. Observations derived from processing steps of 2D ANSI regarding basic AN characteristics (periodicity and location of noise-sources activity and body-to-...
Seismic arrays, first introduced in the late 1950s to detect underground nuclear explosions, have helped to improve our knowledge about the structure of the Earth for the last 40 years. During these years, numerous array processing methods have been developed that use the high signal coherence and...
The Bayesian optimization approach is used to solve for the SVM’s optimal configuration49. There are different approaches to ensure sufficient regularization of single models. In the present work, different regularization techniques are applied to meet the individual models, simulation cost and ...
To optimally extract the principal components, i.e., the signals, from the Hankel matrix of an updated data, we aim at solving the following optimization problem $$\begin{array}{l}{\mathrm{min}}\left\| {\mathscr{E}} \right\|_{F}^{2}\\ {\mathrm{s.t.}}\,{\mathrm{rank}}({\...
Further, data processing steps generally target the optimization of the correlation signal-to-noise (SNR) ratio by minimizing bias associated with nonstationary components of the wavefield. Our strategy includes spectral whitening and amplitude clipping at 3 times the standard deviation of the amplitude...

However, realtime monitoring of the development of fractures and faults in the subsurface remains pivotal to the optimization and safety of this process. This study demonstrates the applicability of a source-independent diffraction imaging method applied to passive seismic imaging for subsurface monitoring...
Given the conservative assumptions made in the design of the shared anchor in this study, including the use of global design safety factors prescribed in standards adopted by the oil and gas sector, it is likely that further detailed design and optimization could be made to reduce costs while ...
The architecture of magma plumbing systems plays a fundamental role in volcano eruption and evolution. However, the precise configuration of crustal magma reservoirs and conduits responsible for supplying eruptions are difficult to explore across most active volcanic systems. Consequently, our understanding ...
An optimization may be performed using information about a unit (one or more of geometry, mass distribution, center of mass, etc.) to generate a model that may be constructed for the unit. Such a model may be a control model. A marine seismic acquisition system can include a frame that ...
