Attenuation of the Vibration in a Non-ideal Excited Flexible Electromechanical System Using a Shape Memory Alloy Actuator
(2021-01-01)
This paper presents the implementation of a Shape Memory Alloy (SMA) actuator in a so-called non-ideal system with the objective of reducing the mechanical vibrations and the Sommerfeld effect present in this kind of system. ...
Attenuation mechanisms in fractured fluid-saturated porous rocks: a numerical modelling study
(Wiley Blackwell Publishing, Inc, 2019-05)
Seismic attenuation mechanisms receive increasing attention for the characterization of fractured formations because of their inherent sensitivity to the hydraulic and elastic properties of the probed media. Attenuation ...
On amplitude information carried by the ambient seismic field
The use of the ambient seismic field (ASF) to extract Earth’s response has received significant attention in the last several years. Multiple studies demonstrate the utility of the ASF for estimating high-resolution velocity ...

Tide-induced head fluctuations in coastal aquifers of variable thickness
(John Wiley & Sons Ltd, 2020-10-15)
In this work, a new analytical solution to describe tide-induced head fluctuations in aquifers of variable thickness is presented. The proposed model assumes a finite and confined aquifer with a thickness that increases ...
Calibration of the local magnitude scale (ML) for Peru
(Springer Verlag, 2017-07)
We propose a local magnitude scale (M L ) for Peru, based on the original Richter definition, using 210 seismic events between 2011 and 2014, recorded by 35 broadband stations of the National Seismic Network operated by ...
