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 ...
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. ...

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. ...
Nonlinear wave propagation through multiple scattering media and virtual time reversal focusing
(Acoustical Society of America, 2020)
In this work, the propagation of an ultrasonic nonlinear wave through a multiple scattering medium is experimentally studied. The interaction between multiple scattering and nonlinear phenomena is analyzed by the cross ...
Excitonic instabilities and spontaneous time-reversal symmetry breaking on the honeycomb lattice
(2014-01-16)
We elucidate the close relationship between spontaneous time-reversal symmetry breaking and the physics of excitonic instabilities in strongly correlated multiband systems. The underlying mechanism responsible for the ...

Jurassic-Early Cretaceous intermediate virtual geomagnetic poles and Pangaean subduction zones
(Elsevier Science, 2008-02)
The objective of this paper is to show that the distribution of Jurassic-Early Cretaceous intermediate virtual geomagnetic poles (VGPs) seems to be conditioned by Pangaean subducted slabs. Palaeomagnetic data from between ...
