  • AR modeling of the speech autocorrelation to improve noisy speech recognition 

    Hernando Pericás, Francisco Javier; Nadeu Camprubí, Climent (1992)
    Text en actes de congrés
    Accés obert
    Speech recognition in noisy environments remains an unsolved problem even in the case of isolated word recognition with small vocabularies. Recently, several techniques have been proposed to alleviate this problem. Concretely, ...

  • Arbitrary Lagrangian-Eulerian (ALE) formulation for hyperelastoplasticity 

    Rodríguez Ferran, Antonio; Pérez Foguet, Agustí; Huerta, Antonio (Wiley and Sons, 2002-02)
    Article
    Accés obert
    The arbitrary Lagrangian-Eulerian (ALE) description in non-linear solid mechanics is nowadays standard for hypoelastic-plastic models. An extension to hyperelastic-plastic models is presented here. A fractional-step method ...
  • Arbitrary lagrangian-eulerian finite element analysis of strain localization in transient problems 

    Pijaudier-Cabot, Gilles; Bode, L; Huerta, Antonio (John Wiley & Sons, 1995-10)
    Article
    Accés obert
    Non-local models guaranty that finite element computations on strain softening materials remain sound up to failure from a theoretical and computational viewpoint. The non-locality prevents strain localization with zero ...
  • Arbitrary Lagrangian-Eulerian formulation for fluid-rigid body interaction 

    Sarrate Ramos, Josep; Huerta, Antonio; Donea, J (2001-03)
    Article
    Accés obert
    A new formulation for two-dimensional fluid–rigid body interaction problems is developed. In particular, vortex-induced oscillations of a rigid body in viscous incompressible flow are studied. The incompressible Navier–Stokes ...
  • Arbitrary lagrangian-eulerian formulation of quasistatic nonlinear problems 

    Rodríguez Ferran, Antonio (Universitat Politècnica de Catalunya, 1996-10-18)
    Tesi
    Accés obert
    En esta tesis se presenta una metodología para la simulación numérica de procesos cuasistaticos en mecánica de sólidos no lineal, basada en una formulación arbitrariamente lagrangiana-euleriana (ale) del problema. Se hace ...

    Capítol de llibre
    Accés restringit per política de l'editorial
    Aim of the present chapter is to provide an in-depth survey of arbitrary Lagrangian-Eulerian (ALE) methods, including both conceptual aspects of the mixed kinematical description and numerical implementation details. ...
  • Arbitrary Lagrangian-Eulerian simulation of powder compaction processes

    Article
    Accés obert
    The arbitrary Lagrangian–Eulerian (ALE) description in non-linear solid mechanics is nowadays stan- dard for hypoelastic–plastic models. An extension to hyperelastic–plastic models is presented here. A fractional-step ...
  • Arbitrary wave synthesis using spectral transformations 

    Ferrando Bataller, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 1993)
    Text en actes de congrés
    Accés obert
    The different transformations among plane, cylindrical and spherical spectrum allow to tackle the arbitrary field synthesis from a set of known sources. Putting all the spectrums in the same coordinate axis we can obtain ...
