A source time reversal method for seismicity induced by mining
(American Institute of Mathematical Sciences, 2017)
In this work, we present a modified Time-Reversal Mirror (TRM) Method, called Source Time Reversal (STR), to find the spatial distribution of a seismic source induced by mining activity. This methodology is based on a known ...
Time-reversal, irreversibility and arrow of time in quantum mechanics
(Springer, 2006-03)
The aim of this paper is to analyze time-asymmetric quantum mechanics with respect of its validity as a non time-reversal invariant, time-asymmetric theory as well as of its ability to determine an arrow of time.
Roads to the past: how to go and not to go backward in time in quantum theories
(Springer Netherlands, 2019-03-18)
In this article I shall defend, against the conventional understanding of the matter, that two coherent and tenable approaches to time reversal can be suitably introduced in standard quantum mechanics: an “orthodox” approach ...
Source time reversal (STR) method for linear elasticity
(Elsevier Ltd, 2019)
© 2018 Elsevier Ltd We study the problem of source reconstruction for a linear elasticity problem applied to seismicity induced by mining. We assume the source is written as a variable separable function f(x)g(t). We first ...
A performance evaluation of electromagnetic time reversal method for locating faults in branched cable networks
(2019-01-25)
The post-failure impedance estimative method is one of the most used ways to locate faults in distribution systems. However, the presence of the distributed generation can degrade the precision of this kind of procedure. ...
A Performance Evaluation of Electromagnetic Time Reversal Method for Locating Faults in Branched Cable Networks
(Ieee, 2018-01-01)
The post-failure impedance estimative method is one of the most used ways to locate faults in distribution systems. However, the presence of the distributed generation can degrade the precision of this kind of procedure. ...
Impact Localization in Composites Using Time Reversal, Embedded PZT Transducers, and Topological Algorithms
(2020-03-17)
Time reversal is a powerful imaging processing technique that focuses waves at their original source using a single receiver transducer when diffusive wave field conditions are met. This has been successfully proved on ...
Baseline-free Damage Imaging Algorithm using Spatial Frequency Domain Virtual Time Reversal
(2021-01-01)
Structural health monitoring techniques are widely used in industry applications to guarantee the integrity of several types of components. This article proposes a baseline-free damage imaging algorithm based on Spatial ...
Singular perturbation problems for time-reversible systems
(Amer Mathematical Soc, 2005-01-01)
In this paper singularly perturbed reversible vector fields defined in R-n without normal hyperbolicity conditions are discussed. The main results give conditions for the existence of infinitely many periodic orbits and ...
Time reversal focusing in the audible range using a tunable sonic crystal
(Journal of Animal Ecology, 2021-06)
Time reversal (TR) focusing of acoustical waves is a widely studied phenomenon that usually requires a chaotic cavity or disordered scattering medium to achieve spatial and frequency decorrelation of the acoustic field ...
