Dynamic Discontinuous Control for Active Control of Mechanical Vibrations
Published 2010-02-01“…This article shows the use of the discontinuous control using dynamic sliding modes for the active isolation of vibrations in mechanical systems. This type of control law constitutes a robust feedback control policy due to its insensitivity to external disturbance inputs, certain immunity to model parameter variations, within known bounds, and to the ever present modelling errors. …”

An experimental study on footsteps sound recognition as biometric under noisy conditions
Published 2022-11-01“…The process of identification of a person is based on the study of footstep signals captured when walking over a sensing area, and the registering of sounds, pressure, vibration, or a combination of these measures. Application of this biometric can emerge in security systems, that identify persons who enter or leave a space, and in providing help to elderly and disabled persons. …”

Un collectionneur dans le siècle : entretien avec Hervé Fischer
Published 2021-04-01“…Émigré à New York, puis à Buenos Aires, il y a quand même suivi la tradition familiale, incluant cette différence radicale que faisait son père entre la valeur de l’art et son commerce. C’est la vibration de l’œil qui compte. Et il est resté fidèle à cette idée que l’art, comme la musique, se juge à l’écho esthétique que l’on ressent, comme le lui disait aussi Marcel Duchamp. …”

Comparative Analysis between Singular Spectral Analysis and Empirical Mode Decomposition for Structural Damage Detection
Published 2023-10-01“…Context: In recent years, thanks to technological advances in instrumentation and digital signal processing, noninvasive methods to detect structural damage have become increasingly important. Vibration-based structural health monitoring (SHM) techniques allow detecting the presence and location of damage from permanent changes in the fundamental frequencies of signals. …”
