Development of a mechanical strain sensor based on time reversal of ultrasonic guided waves
(IEEE, 2014-09-03)
The development of a strain sensor based on the time reversal focusing technique is presented. The sensor is composed by a strip of aluminum plate with two ultrasonic piezocomposite transducers bonded at the ends of the ...
Effect of chaos in a one-channel time-reversal acoustic mirror
(American Physical Society, 2019-07)
Time-reversal of propagating waves has been intensely studied during the last years and successfully implemented in different experimental contexts. It has been argued that ergodic or chaotic ray dynamics improve the ...

Reversible Hamiltonian Liapunov center theorem
(2005-02-01)
We study the existence of periodic solutions in the neighbourhood of symmetric (partially) elliptic equilibria in purely reversible Hamiltonian vector fields. These are Hamiltonian vector fields with an involutory reversing ...

Application of one-bit time reversal technique to mechanical strain monitoring in plates
(IEEEChicago, Illinois, 2014-09-03)
This paper presents the application of the one-bit
time reversal technique to a longitudinal strain sensor. The setup
consists of a pair of piezoelectric transducers bonded in the
extremities of a strip of aluminum ...
Detection of time reversibility in time series by ordinal patterns analysis
(2018-12-01)
Time irreversibility is a common signature of nonlinear processes and a fundamental property of non-equilibrium systems driven by non-conservative forces. A time series is said to be reversible if its statistical properties ...
