  • Origin and modelling of cold dark matter halo properties: IV. Triaxial ellipticity 

    Salvador-Solé, Eduard; Serra, Sinué; Manrique, Alberto; González Casado, Guillermo (2011-04-15)
    Report de recerca
    Accés obert
    In the three preceding papers in the series, we presented a model dealing with the global and small-scale structure and kinematics of hierarchically assembled, virialised, collisionless systems, which correctly accounted ...
  • A technique to composite a modified Newton's method for solving nonlinear equations 

    Grau Sánchez, Miguel; Díaz Barrero, José Luis (2011-05-02)
    Report de recerca
    Accés obert
    A zero-finding technique for solving nonlinear equations more efficiently than they usually are with traditional iterative methods in which the order of convergence is improved is presented. The key idea in deriving this ...
  • On computational order of convergence of some multi-precision solvers of nonlinear systems of equations 

    Grau Sánchez, Miguel; Grau Gotés, Mª Ángela; Díaz Barrero, José Luis (2011-05-02)
    Report de recerca
    Accés obert
    In this paper the local order of convergence used in iterative methods to solve nonlinear systems of equations is revisited, where shorter alternative analytic proofs of the order based on developments of multilineal ...
  • Estudi de la transformació de l'espai de color RGB a l'espai de color HSV 

    Grau Gotés, Mª Ángela; Grau Sánchez, Miguel; Montseny Masip, Eduard; Sobrevilla Frisón, Pilar (2008-09-26)
    Report de recerca
    Accés obert
    S’apliquen les tècniques clàssiques de propagació de l’error a la transformació de l’espai de color RGB en l’espai de color HSV a un conjunt de 1098 imatges test. El conjunt d’imatges test són 183 paletes de color i sis ...
