High-quality resonances in quasi-periodic clusters of scatterers for flexural waves
(American Institute of Physics, 2022-07-04)
Multiple scattering theory is applied to the study of clusters of point-like scatterers attached to a thin elastic plate and arranged in quasi-periodic distributions. Two types of structures are specifically considered: ...
Resilience in Teachers: Validation of the Spanish Version of the CD-RISC10© Scale in Early Childhood, Primary and Special Education Teachers
(MDPI, 2022-09-22)
Schools are a fundamental context for processes of promotion and generation of resilience,
since they focus not only on aspects of academic development, but also of personal and social
development. Resilience in the ...
Edge modes for flexural waves in quasi-periodic linear arrays of scatterers
(American Institute of Physics, 2021-08-13)
We present a multiple scattering analysis of robust interface states for flexural waves in thin elastic plates. We show that finite clusters of linear arrays of scatterers built on a quasi-periodic arrangement support ...
Dipolar localization of waves in twisted phononic crystal plates
(American Physical Society, 2021-01-11)
The localization of waves in two-dimensional clusters of scatterers arranged in relatively twisted
lattices is studied by multiple scattering theory. It is found that, for a given frequency, it is always
possible to nd ...
Strong dipolar interaction in aperiodic Twisted Phononic Crystal Plates – METAMATERIALS 2021
(IEEE, 2021)
Localization of waves is studied by means of multiple scattering theory in a (2D)
arrangement configuration. Studied structures belong to the so called twisted lattices. Results
found show that, for a given frequency, ...
Substationarity for spatial point processes
(Elsevier Inc., 2019-05)
This article aims to introduce the concept of substationarity for spatial point processes
(SPPs). Substationarity is a new concept that has never been studied in the literature. Substationarity means that the distribution ...
The IPIN 2019 Indoor Localisation Competition—Description and Results
(IEEE, 2020-11-10)
IPIN 2019 Competition, sixth in a series of IPIN competitions, was held at the CNR Research Area of Pisa (IT), integrated into the program of the IPIN 2019 Conference. It included two on-site real-time Tracks and three ...
Covariance functions for multivariate Gaussian fields evolving temporally over planet earth
(Springer-Verlag GmbH Germany, part of Springer Nature, 2019-07-18)
The construction of valid and flexible cross-covariance functions is a fundamental task for modeling multivariate space–
time data arising from, e.g., climatological and oceanographical phenomena. Indeed, a suitable ...
Inverse Grating Problem: Efficient Design of Anomalous Flexural Wave Reflectors and Refractors
(American Physical Society, 2019-01-11)
We present an extensive formulation of the inverse grating problem for flexural waves in which the energy of each diffracted mode is selected and the grating configuration is then obtained by our solving a linear system ...
Shaping the Amplitude and Phase of Laser Beams by Using a Phase-only Spatial Light Modulator
(Journal of Visualized Experiments, 2019-01-29)
The aim of this article is to visually demonstrate the utilization of an interferometric method for encoding complex fields associated with coherent
laser radiation. The method is based on the coherent sum of two uniform ...
