    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 ...
  • A novel predictive PCE-based protection strategy for resilient transport networks 

    Ramirez, William Fred; Masip Bruin, Xavier; Marín Tordera, Eva (2015-11-21)
    Article
    Open Access
    © 2016. The ever increasing requirements of new Internet applications are pushing to optimize the design of optical networks. A key design criterion in network design is the ability to recover from failures in an agile and ...
  • Methods of data processing for debris flow seismic warning 

    Arattano, Massimo; Coviello, V; Abanco Martínez de Arenzana, Claudia; Hurlimann Ziegler, Marcel; McArdell, Brian, W (2016-08)
    Article
    Restricted access - publisher's policy
    The output of the seismic devices commonly employed for the monitoring of debris flows, such as geophones and seismometers, is a voltage that is directly proportional to the ground vibration velocity. The output signal in ...
  • Debris-flow monitoring for the set-up of a warning and alarm system: experiences from the pyrenees 

    Hurlimann Ziegler, Marcel; Abanco Martínez de Arenzana, Claudia; Moya Sánchez, José; Berenguer Ferrer, Marc; Vilajosana, Ignasi (2016-08)
    Article

    Debris-flow monitoring sites provide many important inputs on their mechanics and strongly improved the understanding on this hazardous process. Monitoring data are the basis for future early warning systems (EWS) and alarm ...
  • A multivariate statistical model of extreme events: an application to the Catalan coast 

    Lin Ye, Jue; García León, Manuel; Gracia Garcia, Vicente; Sánchez-Arcilla Conejo, Agustín (2016-11)
    Article
    Restricted access - publisher's policy
    Wave extreme events can be understood as the combination of Storm-intensity, Directionality and Intra-time distribution. However, the dependence structure among these factors is still unclear. A methodology has been developed ...
  • The solution of linear mechanical systems in terms of path superposition 

    Magrans Fontrodona, Francesc Xavier; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2017-02)
    Article
    Restricted access - publisher's policy
    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 ...
