  • Coupling of numerical and statistical methods in acoustics 

    Díaz Cereceda, Cristina (Universitat Politècnica de Catalunya, 2010-01-10)
    Master thesis
    Open Access
    Problems in the field of vibroacoustics can be modelled in two fundamental ways. On the one hand, they can be addressed in a deterministic way, using numerical methods like the Finite Element Method. On the other hand, ...
  • Efficient models for building acoustics : combining deterministic and statistical methods 

    Díaz Cereceda, Cristina (Universitat Politècnica de Catalunya, 2013-11-15)
    Doctoral thesis
    Open Access
    Modelling vibroacoustic problems in the field of building design is a challenging problem due to the large size of the domains and the wide frequency range required by regulations. Standard numerical techniques, for instance ...
  • Estimation of the vibration reduction index for three-dimensional junctions 

    Jose Sorroche, Guillem de (Universitat Politècnica de Catalunya, 2016-06-20)
    Master thesis
    Open Access
    In the framework of building acoustics design, sound propagation between rooms is a major factor in determining the acoustic insulation levels. Acoustic waves can be directly transmitted through common perimetral surfaces ...
  • Métodos óptimos de resolución de sistemas lineales en acústica computacional 

    Martos López, José (Universitat Politècnica de Catalunya, 2013-01-11)
    Minor thesis
    Restricted access - author's decision
    Esta tesina intenta encontrar un procedimiento de resolución optimizada de los sistemas lineales resultantes de la modelización de problemas de propagación acústica de manera que las exigencias de cálculo no se conviertan ...
  • Numerical modelling of impact noise 

    Díaz Cereceda, Cristina (Universitat Politècnica de Catalunya, 2009-06-01)
    Minor thesis
    Open Access
    El objetivo de esta investigación es desarrollar modelos determinísticos que permitan evaluar el aislamiento frente a ruido de impacto para diferentes tipos de forjados. Estos modelos abordan el problema mediante una ...
  • Representació gràfica de mapes d’accessibilitat aplicat al cas de Barcelona 

    Guerrero Morales, Isabel (Universitat Politècnica de Catalunya, 2012-06-29)
    Master thesis (pre-Bologna period)
    Open Access
    En aquest projecte s’estudia la connectivitat i l’accessibilitat de l’Aeroport de Barcelona comparant-la amb altres aeroports internacionals i nacionals, depenent de variables com el nombre de rutes, el número de vols i ...
  • Variant de les carreteres C-31, C-252 i GI-634 al seu pas per Verges 

    Martínez Rodríguez, Eduardo (Universitat Politècnica de Catalunya, 2015-06)
    Master thesis (pre-Bologna period)

  • Vibroacoustic coupling and transmission paths 

    Magrans Fontrodona, Francesc Xavier (Universitat Politècnica de Catalunya, 2018-12-21)
    Doctoral thesis
    Open Access
    This dissertation deals with four topics. The first three are in the same environment, the transmission paths. The fourth refers to the synthesis of subsystems and more specifically to two subsystems linked by any number ...
