  • A Reduced Order Modeling approach for optimal allocation of Distributed Generation in power distribution systems 

    García Blanco, Raquel; Díez, Pedro; Borzacchiello, Domenico; Chinesta, Francisco (2016)
    Conference report

    This paper presents an “offline-online” strategy for optimal allocation and sizing of Distributed Generation. In traditional optimization approaches, each function evaluation requires the solution of a power flow problem, ...
  • Building performance at low frequency range including flanking transmissions 

    Guigou-Carter, Catherine; Poblet-Puig, Jordi (Deutsche Gesellschaft für Akustik e.V. (DEGA), 2016)
    Conference report
    Restricted access - publisher's policy
    Recent researches have proposed alternative formulas for the estimation of the vibration reduction index (Kij) at junctions. Among other aspects, the new approaches propose different expressions for the low, mid and high ...
  • Amplified catalogue of vibration reduction index formulas for junctions based on numerical simulations 

    Poblet-Puig, Jordi; Guigou-Carter, Catherine (Deutsche Gesellschaft für Akustik e.V. (DEGA), 2016)
    Conference report

    The vibration reduction index (Kij) is a key parameter in the prediction of flanking transmissions according to the EN-12354 standard. Formulas for the evaluation of Kij in L, T and X junctions that depend on the mass ratio ...
  • Sub-structuring of mechanical systems based on the path concept 

    Magrans Fontrodona, Francesc Xavier; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (Deutsche Gesellschaft für Akustik e.V. (DEGA), 2016)
    Conference report

    Real mechanical systems are usually complex. Their modelling with discretisation techniques involve a large number of degrees of freedom/unknowns. This leads to high computational costs especially at high frequencies. An ...
  • The solution of linear mechanical systems in terms of path superposition 

    Magrans Fontrodona, Francesc Xavier; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2017-02)
    Article

    We prove that the solution of any linear mechanical system can be expressed as a linear combination of signal transmission paths. This is done in the framework of the Global Transfer Direct Transfer (GTDT) formulation for ...
  • Regression curves for vibration transmission across junctions of heavyweight walls and floors based on finite element methods and wave theory 

    Hopkins, Carl; Crispin, Charlotte; Poblet-Puig, Jordi; Guigou-Carter, Catherine (2016-12)
    Article
    Restricted access - publisher's policy
    Sound insulation prediction models in European and International standards use the vibration reduction index to calculate flanking transmission across junctions of walls and floors. These standards contain empirical ...
  • A modal-spectral model for flanking transmissions 

    Poblet-Puig, Jordi (2016-11)
    Article
    Restricted access - publisher's policy
    A model for the prediction of direct and indirect (flanking) sound transmissions is presented. It can be applied to geometries with extrusion symmetry. The structures are modelled with spectral finite elements. The acoustic ...
  • Tutorial on Hybridizable Discontinuous Galerkin (HDG) for second-order elliptic problems 

    Sevilla Càrdenas, Ruben; Huerta, Antonio (Springuer International Publishing, 2016)
    Part of book or chapter of book
    Restricted access - publisher's policy
    The HDG is a new class of discontinuous Galerkin (DG) methods that shares favorable properties with classical mixed methods such as the well known Raviart-Thomas methods. In particular, HDG provides optimal convergence of ...
  • Master-slave approach for the modelling of joints with dependent degrees of freedom in flexible mechanisms 

    Muñoz Romero, José; Jelenic, Gordan; Crisfield, M. A. (2003-08-06)
    Article
    Open Access
    The analysis of multibody systems requires an exact description of the kinematics of the joints involved. In the present work the master–slave approach is employed and endowed with the possibility of including several more ...
  • Spectral analysis of the Beznar dam accelerogram. Comparison with results in the northeastern of Spain 

    Canas Torres, José Antonio; Barbat Barbat, Horia Alejandro; Pujades Beneit, Lluís; Egozcue Rubí, Juan José; Sarrate Ramos, Josep (1991-12)
    Article
    Open Access
    Numerical analysis applied to the Beznar dam accelerograms (longitudinal and transversal components) shows that the Fourier amplitude spectrum is a good approximation to the pseudo-velocity spectra. Thís fact makes possible ...
