A Novel Low Processing Time System for Criminal Activities Detection Applied to Command and Control Citizen Security Centers

Suarez-Paez, Julio; Salcedo-Gonzalez, Mayra; Climente, Alfonso; Esteve Domingo, Manuel; Gomez, J.A.; Palau Salvador, Carlos Enrique; Pérez Llopis, Israel (MDPI AG, 2019-12)

[EN] This paper shows a Novel Low Processing Time System focused on criminal activities detection based on real-time video analysis applied to Command and Control Citizen Security Centers. This system was applied to the ...
Analysis of flexural wave cloaks

Climente Alarcón, Alfonso; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (AIP Publishing, 2016-12)

This work presents a comprehensive study of the cloak for bending waves theoretically proposed by Farhat et al. [see Phys. Rev. Lett. 103, 024301 (2009)] and later on experimentally realized by Stenger et al. [see Phys. ...
CITRINE: Common Intelligence and Traceability for Rescue and Identification Operations

Climente Alarcón, Alfonso (Universitat Politècnica de València, 2012-01-11)

The Master Thesis is part of the European project CITRINE. A command and control system for crisis management has been build making use of DSS and a civil version of the military standar C2IEDM. The system uses sensors ...
Experimental evidence of rainbow trapping and Bloch oscillations of torsional waves in chirped metallic beams

Arreola-Lucas, Arturo; Baez, Gabriela; Cervera Moreno, Francisco Salvador; Climente Alarcón, Alfonso; Mendez-Sanchez, R.A.; Sánchez-Dehesa Moreno-Cid, José (Nature Publishing Group, 2019)

[EN] The Bloch oscillations (BO) and the rainbow trapping (RT) are two apparently unrelated phenomena, the former arising in solid state physics and the latter in metamaterials. A Bloch oscillation, on the one hand, is a ...
Gradient index lenses for flexural waves based on thickness variations

Climente Alarcón, Alfonso; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics, 2014-08-11)

This work presents a method for the realization of gradient index devices for flexural waves in thin plates. Unlike recent approaches based on phononic crystals, the present approach is based on the thickness-dependence ...
Implementación y pruebas en un Honeypot en una red corporativa conectada a Internet.

de Scals Polop, Pablo (Universitat Politècnica de València, 2024-10-10)

[ES] En la actualidad, donde las amenazas cibernéticas son cada vez más sofisticadas, el testeo de herramientas como los Honeypots se vuelve fundamental para fortalecer la ciberseguridad. El objetivo del TFG será la ...
Omnidirectional broadband acoustic absorber based on metamaterials

Climente Alarcón, Alfonso; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics, 2012-04-06)

We present the design, construction, and experimental characterization of the acoustic analogue of the so called photonic black-hole. The fabricated sample has cylindrical symmetry and consists of two parts, a shell that ...
Omnidirectional broadband insulating device for flexural waves in thin plates

Climente Alarcón, Alfonso; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics (AIP), 2013)

This work presents a gradient index device for insulating from vibrations a circular area of a thin plate. The gradient of the refractive index is achieved exploiting the thickness-dependence of the dispersion relation of ...
Refractive devices for acoustical and flexural waves

Climente Alarcón, Alfonso (Editorial Universitat Politècnica de València, 2015-03-31)

The aim of this work has been the design and demonstration of refractive devices, not only for acoustic waves, but also for flexural waves in thin plates. Mathematically these problems have been treated by means of the ...
Scattering of flexural waves from a hole in a thin plate with an internal beam

Climente Alarcón, Alfonso; Norris, A.N.; Sánchez-Dehesa Moreno-Cid, José (Acoustical Society of America, 2015-01)

The scattering of flexural waves by a hole in a thin plate traversed by a beam is modeled here by coupling the Kirchhoff Love and the Euler Bernoulli theories. A closed form expression is obtained for the transfer matrix ...
Single-phase metamaterial plates for broadband vibration suppression at low frequencies

Gao, Penglin; Climente Alarcón, Alfonso; Sánchez-Dehesa Moreno-Cid, José; Wu, Linzhi (Elsevier, 2019)

[EN] By studying platonic crystals based on lattices of cavities containing N-beam resonators, we conclude that crystals made of 1-beam resonators easily produce low-frequency omnidirectional bandgaps. Based on this favorable ...
Sound focusing by gradient index sonic lenses

Climente Alarcón, Alfonso; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Institute of Physics (AIP), 2010-09-06)

Gradient index sonic lenses based on two-dimensional sonic crystals are here designed, fabricated, and characterized. The index-gradient is achieved in these type of flat lenses by a gradual modification of the sonic crystal ...
Theoretical study of platonic crystals with periodically structured N-beam resonators

Gao, Penglin; Climente Alarcón, Alfonso; Sánchez-Dehesa Moreno-Cid, José; Wu, Linzhi (American Institute of Physics, 2018-03)

[EN] A multiple scattering theory is applied to study the properties of flexural waves propagating in a plate with periodically structured N-beam resonators. Each resonator consists of a circular hole containing an inner ...
Three-dimensional axisymmetric cloak based on the cancellation of acoustic scattering from a sphere

Sanchis Martínez, Lorenzo; García Chocano, Víctor Manuel; Llopis Pontiveros, Rafael; Climente Alarcón, Alfonso; Martínez Pastor, J.; Cervera Moreno, Francisco Salvador; Sánchez-Dehesa Moreno-Cid, José (American Physical Society, 2013-03-20)

This Letter presents the design, fabrication, and experimental characterization of a directional threedimensional acoustic cloak for airborne sound. The cloak consists of 60 concentric acoustically rigid tori surrounding ...
