    • A representation of cloth states based on a derivative of the Gauss linking integral 

      Coltraro, Franco; Fontana, Josep; Amorós Torrent, Jaume; Alberich Carramiñana, Maria; Borràs Sol, Júlia; Torras, Carme (Elsevier, 2023-11-15)
      Article
      Open Access
      Robotic manipulation of cloth is a complex task because of the infinite-dimensional shape-state space of textiles, which makes their state estimation very difficult. In this paper we introduce the dGLI Cloth Coordinates, ...
    • An inextensible model for the robotic manipulation of textiles 

      Coltraro, Franco; Amorós Torrent, Jaume; Alberich Carramiñana, Maria; Torras, Carme (2022-01-01)
      Article
      Open Access
      We introduce a new isometric strain model for the study of the dynamics of cloth garments in a moderate stress environment, such as robotic manipulation in the neighborhood of humans. This model treats textiles as surfaces ...
    • Bouncing cosmologies via modified gravity in the ADM formalism: Application to loop quantum cosmology 

      Haro Cases, Jaume; Amorós Torrent, Jaume (American Physical Society (APS), 2018-03-15)
      Article
      Open Access
      We consider the Arnowitt-Deser-Misner formalism as a tool to build bouncing cosmologies. In this approach, the foliation of the spacetime has to be fixed in order to go beyond general relativity modifying the gravitational ...
    • Bouncing loop quantum cosmology from F(T) gravity 

      Amorós Torrent, Jaume; Haro Cases, Jaume; Odintsov, Sergei D. (2013-05)
      Article
      Open Access
      The big bang singularity could be understood as a breakdown of Einstein’s general relativity at very high energies. By adopting this viewpoint, other theories that implement Einstein cosmology at high energies might solve ...
    • Computation of critical current in artificially structurated bulk samples from Hall measurements 

      Carrera, Miquel; Granados García, Xavier; Amorós Torrent, Jaume; Maynou Gil, Roger; Puig Molina, Teresa; Obradors Berenguer, Xavier (Institute of Physics (IOP), 2008)
      Article
      Open Access
      High-temperature superconducting artificially structured bulk samples, such as bulks with slanted drills or welds of different pieces along the c-axis with holes drilled in different asymmetric positions, ...
    • Current distribution in HTSC tapes obtained by inverse problem calculation 

      Carrera, Miquel; Granados García, Xavier; Amorós Torrent, Jaume; Maynou Gil, Roger; Puig Molina, Teresa; Obradors Berenguer, Xavier (Institute of Physics (IOP), 2010)
      Article
      Open Access
      The development of SC devices based on HTSC tapes requires a deep knowledge of the current distribution in both pre-saturation and post-saturation regimes. Magnetic measurements have shown the possibilities ...
    • Current distributions in wide YBCO tapes 

      Carrera, Miquel; Granados García, Xavier; Amorós Torrent, Jaume; Puig Molina, Teresa; Obradors Berenguer, Xavier (Elsevier, 2012)
      Article
      Open Access
      The need of a better mechanical behaviour and the stabilization of coated conductors for applications, as Magnets, cables or Fault Current Limiters, has motivated the lamination of tapes with stainless steel or copper ...
    • Developable surfaces with prescribed boundary 

      Alberich Carramiñana, Maria; Amorós Torrent, Jaume; Coltraro, Franco (Springer-Birkhäuser, 2021)
      Part of book or chapter of book
      Open Access
      It is proved that a generic simple, closed, piecewise regular curve in space can be the boundary of only infinitely many developable surfaces with nonvanishing mean curvature. The relevance of this result in the context ...
    • Discrepancies between observational data and theoretical forecast in single field slow roll inflation 

      Amorós Torrent, Jaume; Haro Cases, Jaume (2016-09-09)
      Article
      Open Access
      The PLANCK collaboration has determined, or greatly constrained, values for the spectral parameters of the CMB radiation, namely the spectral index ns, its running as, the running of the running ßs, using a growing body ...
    • Generic behaviour of asymptotically holomorphic Lefschetz pencils 

      Amorós Torrent, Jaume; Muñoz, Vicente; Presas, Francisco (World Scientific, 2005)
      Article
      Open Access
      We prove that the vanishing spheres of the Lefschetz pencils constructed by Donaldson on symplectic manifolds of any dimension are conjugated under the action of the symplectomorphism group of the fiber. More precisely, ...
