    • Exponential decay in one-dimensional porous-thermo-elasticity 

      Sánchez Casas, José Pablo; Quintanilla de Latorre, Ramón (2004)
      Article
      Accés obert
      This paper concerns the one dimensional problem of the porous-thermo-elasticity. Two kinds of dissipation process are considered: the viscosity type in the porous structure and the thermal dissipation. It is known that ...

    • Exponential stability in thermoelasticity with microtemperatures 

      Sánchez Casas, José Pablo; Quintanilla de Latorre, Ramón (2003)
      Article
      Accés obert
      This article is concerned with a linear theory for elastic materials with inner structure, whose particles in addition to the classical displacement, possess microtemperatures. In the main part of the paper we restrict ...

    • Numerical study of hopf bifurcations in the two-dimensional plane poiseuille flow 

      Sánchez Casas, José Pablo (Universitat Politècnica de Catalunya, 2002-11-28)
      Tesi
      Accés obert
      In this work we try to analyse the dynamics of the Navier-Stokes equations in a problem without domain complexities as is the case of the plane Poiseuille flow. The Poiseuille problem is described as the flow of a viscous ...

    • The frequency map for billiards inside ellipsoids 

      Ramírez Ros, Rafael; Sánchez Casas, José Pablo (2010-04)
      Report de recerca
      Accés obert
      The billiard motion inside an ellipsoid Q Rn+1 is completely integrable. Its phase space is a symplectic manifold of dimension 2n, which is mostly foliated with Liouville tori of dimension n. The motion on each Liouville ...

    • Unstable manifolds computation for the 2-D plane Poiseuille flow 

      Sánchez Casas, José Pablo; Jorba, Angel (2003)
      Article
      Accés obert
      We follow the unstable manifold of periodic and quasi-periodic solutions for the Poiseuille problem, using two formulations: holding constant flux or mean pressure gradient. By means of a numerical integrator of the ...

    • Unstable manifolds computation for the two-dimensional plane Poiseuille flow 

      Sánchez Casas, José Pablo; Jorba, Angel (2003)
      Article
      Accés obert
      In this work we study some aspects of the dynamics of the plane Poiseuille problem in dimension 2, in what refers to the connection among different configurations of the flow. The fluid is confined in a channel of plane ...
