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 ...

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 ...

La focalización de ondas acústicas que se propagan por un medio inhomogéneo fue lograda con éxito a través del procedimiento conocido como espejo de reversión temporal (TRM). En este experimento, las ondas salientes son ...

The focused signal obtained by the time-reversal or the cross-correlation techniques of ultrasonic guided waves in plates changes when the medium is subject to strain, which can be used to monitor the medium strain level. ...

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 ...

We introduce jump processes in R(k), called density-profile processes, to model biological signaling networks. Our modeling setup describes the macroscopic evolution of a finite-size spin-flip model with k types of spins ...

This dissertation studies the detection and reconstruction of the space term for a variable separable source in acoustic and elastic wave problems. To do this, we study the time-reversal mirror method, which exploits an ...

Traditional studies on sexual communication have focused on the exchange of signals during courtship.However, communication between the sexes can also occur during or after copulation. Allocosa brasilien-sis is a wolf ...

La presente tesis de maestría presenta la implementación en entorno simulado de una estrategia de reducción de información y localización de objetivos, basada en el procesamiento de señales acústicas submarinas usando los ...
