      Article
      Accés restringit per política de l'editorial
      We show that periodic optical lattices imprinted in cubic nonlinear media with strong two-photon absorption and localized linear gain landscapes support stable dissipative defect modes in both focusing and defocusing media. ...

    • Dissipative solitons in binary fluid convection 

      Mercader Calvo, María Isabel; Batiste Boleda, Oriol; Alonso Maleta, María Aránzazu; Knobloch, Edgar (American Institute of Mathematical Sciences, 2011-10-01)
      Article
      Accés restringit per política de l'editorial
      A horizontal layer containing a miscible mixture of two fluids can produce dissipative solitons when heated from below. The physics of the system is described, and dissipative solitons are computed using numerical continuation ...

    • Dissipative structures for the system of Moore–Gibson–Thompson thermoelasticity in the whole space

      Article
      Accés restringit per política de l'editorial
      We investigate the dissipative structure for the system of Moore–Gibson–Thompson (MGT) thermoelasticity in the whole space. To analyze the dissipative structure, it is very useful to rewrite the equations into a symmetric ...

      Bessa, Iury; Camargos, Murilo Osorio; Puig Cayuela, Vicenç; Martinez, Reinaldo (2020)
      Text en actes de congrés
      Accés obert
      This paper addresses the problem of dissipativity-based fault tolerant control (FTC) based on fault hiding approach. In particular, a static recon guration block (RB) is used for recon guration of faulty systems. Such block ...

    • Dissolution experiments of commercial PWR (52 MWd/kgU) and BWR (53 MWd/kgU) spent nuclear fuel cladded segments in bicarbonate water under oxidizing conditions. Experimental determination of matrix and instant release fraction
