  • Efficient three-dimensional building-soil model for the prediction of ground-borne vibrations in buildings 

    Clot Razquin, Arnau; Arcos Villamarín, Robert; Romeu Garbí, Jordi (2017-09-01)
    Article
    Accés obert
    This paper proposes a new efficient model for the prediction of low-amplitude ground-borne vibrations in buildings. The model takes into account the three-dimensional nature of the building structure by analytical and ...
  • Numerical study of the aerodynamics of sound sources in a bass-reflex port 

    García Alcaide, V. M.; Pallejà Cabré, S.; Castilla López, Roberto; Gámez Montero, Pedro Javier; Romeu Garbí, Jordi; Pàmies Gómez, Teresa; Amate, Joan; Milán, Natalia (Engineering Applications of Computational Fluid Mechanics, 2017-01-20)
    Article
    Accés obert
    The aim of this paper is to study the aerodynamics phenomena of a bass-reflex port that causes noise in the audible frequency range. After discarding structural and mechanical vibration issues, the hypothesis considered ...
  • Aircraft localization using a passive acoustic method. Experimental test 

    Martín Román, Sara-Regina; Genesca Francitorra, Meritxell; Romeu Garbí, Jordi; Clot Razquin, Arnau (2016-01)
    Article
    Accés restringit per política de l'editorial
    A passive acoustic method for aircraft localization is experimentally tested in this paper. The method relies on the Doppler effect influencing the signals received by a mesh of microphones distributed over the acoustic ...

  • Aplicación de la emisión acústica como método para anticipar el fallo de tejidos colaginosos (1ª parte) 

    García Vilana, Silvia; Martínez González, Eva; Sánchez Molina, David; Arregui Dalmases, Carlos; Velázquez Ameijide, Juan; Llumà Fuentes, Jordi; Rebollo Soria, María Carmen (2016-07-01)
    Article
    Accés obert
    Se usa un montaje experimental basado en Emisión Acústica (EA) para detectar la energía elástica liberada durante el proceso de tracción y rotura de tejidos colaginosos. Se localizan las señales y se cuenta el número de ...
  • Dynamic response of a double-deck circular tunnel embedded in a full-space 

    Clot Razquin, Arnau; Arcos Villamarín, Robert; Romeu Garbí, Jordi; Pàmies Gómez, Teresa (2016-10-01)
    Article
    Accés restringit per política de l'editorial
    A three-dimensional dynamic model for calculating the ground-borne vibrations generated by harmonic loads applied on the interior floor of a double-deck circular tunnel is developed. The response of the system is obtained ...
  • An energy flow study of a double-deck tunnel under quasi-static and harmonic excitations 

    Clot Razquin, Arnau; Romeu Garbí, Jordi; Arcos Villamarín, Robert (2016-10)
    Article
    Accés restringit per política de l'editorial
    This paper presents a comparison between the vibration energy flow radiated by a double-deck tunnel and the one radiated by a simple tunnel when both are excited by constant or by harmonic moving loads. For both cases, the ...
  • Assessment of environmental noise and its effect on neonates in a Neonatal Intensive Care Unit 

    Romeu Garbí, Jordi; Cotrina, Laura; Perapoch, Josep; Linés, Marcos (2016-10-01)
    Article
    Accés obert
    A method for analyzing the influence of noise on newborns is proposed. The method consists of defining three different types of time interval (quiet, noisy and nursing) and, for each period, environmental noise levels, ...
  • Optimization of the active control of turboprop cabin noise 

    Romeu Garbí, Jordi; Palacios, J.; Balastegui Manso, Andreu; Pàmies Gómez, Teresa (2015-09-01)

  • A stochastic model for soft tissue failure using acoustic emission data 

    Sánchez Molina, David; Martínez González, Eva; Velázquez Ameijide, Juan; Llumà Fuentes, Jordi; Rebollo Soria, María Carmen; Arregui Dalmases, Carlos (2015-07-15)
    Article
    Accés obert
    The strength of soft tissues is due mainly to collagen fibers. In most collagenous tissues, the arrangement of the fibers is random, but has preferred directions. The random arrangement makes it difficult to make deterministic ...
