      Article
      Accés obert
      In this paper, a numerical methodology based on a two-and-a-half-dimensional (2.5D) singular boundary method (SBM) to deal with acoustic radiation and scattering problems in the context of longitudinally invariant structures ...

    • Active noise control for open windows 

      Sohrabi, Shahin; Svensson, Peter; Pàmies Gómez, Teresa; Romeu Garbí, Jordi (2021-08-01)
      Article
      Accés restringit per política de l'editorial
      Over the last decades, the applications of the active noise control system are broadened. In this study, the active noise control is modeled to reduce the noise pass through an open window. The objective is to define a ...

    • A 2.5D coupled FEM–SBM methodology for soil–structure dynamic interaction problems 

      Liravi, Hassan; Arcos Villamarín, Robert; Clot Razquin, Arnau; Conto Quispe, Kenny Fernando; Romeu Garbí, Jordi (Elsevier, 2022-01-01)
      Article
      Accés obert
      In this paper, a novel numerical methodology to deal with longitudinally invariant soil–structure interaction problems is proposed. The methodology uses the finite element method to model the structure and the singular ...

    • A predictive model for fracture in human ribs based on in-vitro acoustic emission data 

      García Vilana, Silvia; Sánchez Molina, David; Llumà Fuentes, Jordi; Fernández Osete, Ismael; Velázquez Ameijide, Juan; Martínez González, Eva (2021-09-01)
      Article
      Accés obert
      Purpose The aim of this paper is to propose a fracture model for human ribs based on acoustic emission (AE) data. The accumulation of microcracking until a macroscopic crack is produced can be monitored by AE. The ...
