In this paper, we introduce a new approach to the estimation of the parameters of high quality factor, low natural frequency resonators. Our approach is based on transient measurements of the slowly-varying amplitude and phase response of a resonator to an arbitrary nearly-periodic drive stimulus. We show how this approach may be employed for estim...
Dynamic system fault diagnosis is often faced with a large number of possible faults. The purpose of this paper is to propose an efficient method for such situations. To avoid intractable combinatorial problems, sparse estimation techniques appear to be a powerful tool for isolating faults, under the assumption that only a small number of possible ...
Come ha sottolineato Eugene Wigner, la matematica si è dimostrata efficace, oltre ogni ragionevole aspettativa, nelle scienze fisiche e nelle loro applicazioni tecnologiche. Il ruolo della matematica nelle scienze biologiche, mediche e sociali è stato molto più modesto ma è recentemente cresciuto grazie alla capacità di simulazione offerta dai mode...
Como subrayó Eugene Wigner, las matemáticas han demostrado una eficacia inconmensurable en las ciencias físicas y sus aplicaciones tecnológicas. El papel de las matemáticas en las ciencias biológicas, médicas y sociales ha sido mucho más modesto, pero ha crecido recientemente gracias a la capacidad de simulación que ofrecen los ordenadores modernos...
The acoustic impact of French wind farms is currently estimated by measuring their sound emergence. These measures require the implementation of on/off cycles of the wind farms in order to determine the ambient noise (wind turbines in operation) and the residual noise (stopped wind turbines). These procedures result in very significant losses of el...
The estimation of the ?long-term? (typically representative of one year period) noise level descriptor LeqLT is a major challenge/issue for the characterization of an environmental acoustic situation, whether it concerns road, rail, industrial or other outdoor noise situations. In this work we study the possibility of estimating the above-mentioned...

For many geotechnical purposes, the proper estimation of shapes and dimensions of landslide rupture zones is of significant importance. Very often, this exact delineation is difficult due to the lack of information on rupture zone extents in 3D. Based on a global landslide inventory, this work presents statistical analyses correlating dimension-rel...
This paper considers the problem of set-membership estimation for discrete-time linear time-varying descriptor systems subject to unknown but bounded disturbance and noise. We propose a set-membership estimation method based on a descriptor system observer and a zonotopic estimator of the observer error bounds. The observer parameters are optimized...
