Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (American Physical Society, 2012-04-27)We demonstrate the presence of Dirac cones in the dispersion relation of acoustic waves propagating on the surface of a plate of methyl methacrylate containing a honeycomb lattice of cylindrical boreholes. This structure ... -
Cerdá Jordá, Salvador; Giménez Pérez, Alicia; Cibrián Ortíz de Anda, Rosa (Audio Engineering Society, 2012-06)[EN] Producing a formal means for ranking the quality of concert halls requires that the subjective assessment by experts and listeners be matched to acoustic parameters. Using previous results from Ando and Beranek, the ...

Gómez-Tejedor, José A.; Monsoriu Serra, Juan Antonio (Universitat Politècnica de València, 2014-03-31)[EN] In this paper we present an application for Android mobile device able of measuring the fundamental frequency of a sound very precisely. This application may be used in diverse fields as in music for tuning musical ... -
Zaragozá Martínez, Núria (2011-03-14)Se realiza un estudio sobre el cartografiado de bivalvos solénidos utilizando la información angular del transductor Split beam en tres zonas de la Ría de Pontevedra. Los resultados nos muestran una exitosa correspondencia ... -
Sainz-Pardo Martí, Sara (2011-03-14)El objetivo del trabajo es comprender el comportamiento del atún rojo (Thunnus thynnus) en cautividad y monitorear el proceso de alimentación con técnicas no invasivas. Se realizan medidas dorsales con una ecosonda de haz ... -
Canelo Cohen, Laura Judith (2015-02-25)[EN] Most of the qualities of a woodwind instrument can be determined by calculating the limitations of its acoustic spectrum. For this reason, it is important to understand the mechanism of the instrument before you can ...

Martí Guerola, Amparo; Cobos Serrano, Máximo; López Monfort, José Javier (Acoustical Society of America, 2012-02)Automatic speech recognition (ASR) refers to the task of extracting a transcription of the linguistic content of an acoustical speech signal automatically. Despite several decades of research in this important area of ...

Puig Pons, Vicente; Espinosa Roselló, Víctor; Soliveres González, Ester; Ortega, Aurelio; Belmonte, Antonio; De la Gandara Garcia, Fernando (International Commission for the Conservation of Atlantic Tunas (ICCAT), 2012)[EN] In this paper, an experimental setup to estimate the biomass of caged bluefin tuna (Thunnus thynnus) in the Spanish Mediterranean coast is presented. Aims are to monitor individual tuna during all stages of growth, ... -
Arques Carbonell, Rafael Enrique (2017-10-25)La directiva de estrategia marina establece, mediante la decisión 2010/477/UE, que los estados miembros deben evaluar el buen estado ambiental de sus mares en base a once indicadores o descriptores, y que esa evaluación ... -
Orero Canet, Carlos (2014-05-19)[ES] Desde hace unos años, la industria automotriz reclama alternativas eficientes y ecológicas que sustituyan a los materiales absorbentes fibrosos en los dispositivos de control de ruido y emisiones acústicas (fundamentalmente ...

Conejero, J. Alberto; Lizama, Carlos; Ródenas Escribá, Francisco de Asís (Natural Sciences Publishing, 2015-09)[EN] We study a third-order partial differential equation in the form $\tau u_{ttt} +\alpha u_{tt} -c^2 u_{xx} -b u_{xxt} =0, (1)$$ that corresponds to the one-dimensional version of the Moore-Gibson-Thompson equation ... -
Pérez Bernabeu, Rubén (2018-10-01)En este proyecto se ha realizado un estudio acerca de las lentes Fresnel y su posible aplicación en el entorno de la medicina mediante el uso de ondas de ultrasonido. Este trabajo empieza con un desarrollo teórico de las ... -
Reyes Belmonte, Miguel Ángel (2014-01-07)At the end of the 19th Century, the invention of the Internal Combustion Engine (ICE) marked the beginning of our current lifestyle. Soon after the first ICE patent, the importance of increasing air pressure upstream the ... -
Adrián Martínez, Silvia (2015-04-16)[EN] Neutrino astronomy is a booming field in astroparticle physics. Due to the particular characteristics of neutrinos, these particles offer great advantages as probes for the study of the far and high-energy Universe. ... -
Cebrecos Ruiz, Alejandro; Picó Vila, Rubén; Romero García, Vicente; Yasser, A. M.; Maigyte, L.; Herrero, R.; Botey, M.; Sánchez Morcillo, Víctor José; Staliünas, Kestutis (American Institute of Physics (AIP), 2014-11-17)We study the propagation of waves in a periodic array of absorbing layers. We report an anomalous increase of wave transmission through the structure related to a decrease of the absorption around the Bragg frequencies. ... -
Fuster Fajardo, José Miguel (2014-01-21)Uno de los objetivos en la Acústica de Salas consiste en la creación de un campo sonoro difuso. Los difusores de sonido pueden mejorar el rendimiento acústico de las salas, aumentando la difusión del campo sonoro, la ... -
Torregrosa, A. J.; Serrano, J.R.; Piqueras, P.; García Afonso, Óscar (Elsevier, 2017)[EN] The implementation of tight vehicle emission standards has forced manufactures to use aftertreatment systems extensively. In addition to pollutant emissions abatement, these devices have a noticeable impact on the ... -
Gadea Borrell, José Mª; Segura Alcaraz, Jorge Gabriel; Juliá Sanchis, Ernesto (Springer-Verlag, 2015)[EN] This work has focused on characterizing laminated floors from the sound perception perspective. There are two main aspects in this work. The first is an alternative proposed for experimental characterization, which ... -
Payri González, Francisco; Broatch Jacobi, Jaime Alberto; Serrano Cruz, José Ramón; Piqueras Cabrera, Pedro (Elsevier, 2011-12)Wall-flow particulate filters have been placed as a standard technology for Diesel engines because of the increasing restrictions to soot emissions. The inclusion of this system within the exhaust line requires the development ... -
Denia Guzmán, Francisco David; Sánchez Orgaz, Eva María; Martínez Casas, José; Kirby, Ray (Elsevier, 2015-09-01)A mixed finite element model has been derived for the acoustic analysis of perforated dissipative silencers including several effects simultaneously: (1) High temperature and thermal gradients in the central duct and the ...
