A Probabilistic Tremor Location Method

open access: yesGeophysical Research Letters, 2020
A method to locate tremor with an unclear onset is introduced. The method maps envelopes of cross‐correlated records from pairs of seismographs to signal likelihoods using Bayes' theorem.

Robust Localization for Near- and Far-Field Signals with an Unknown Number of Sources

open access: yesFractal and Fractional, 2023
Source location is a constant issue of importance of both theoretical study and practical engineering. Many pioneers have put out the corresponding solutions for near- or far-field signals, and preferred contributions are suggested. To our best knowledge,

An Upper Mass Limit on a Red Supergiant Progenitor for the Type II-Plateau Supernova SN 2006my [PDF]

open access: yes, 2008
We analyze two pre-supernova (SN) and three post-SN high-resolution images of the site of the Type II-Plateau supernova SN 2006my in an effort to either detect the progenitor star or to constrain its properties. Following image registration, we find that

Acoustic Emission and Artificial Intelligence Procedure for Crack Source Localization

open access: yesSensors, 2023
The acoustic emission (AE) technique is one of the most widely used in the field of structural monitoring. Its popularity mainly stems from the fact that it belongs to the category of non-destructive techniques (NDT) and allows the passive monitoring of ...

UAV-Based Air Pollutant Source Localization Using Combined Metaheuristic and Probabilistic Methods

open access: yesApplied Sciences, 2019
Air pollution is one of the greatest risks for the health of people. In recent years, platforms based on Unmanned Aerial Vehicles (UAVs) for the monitoring of pollution in the air have been studied to deal with this problem, due to several advantages ...
