    • Dynamical behavior of asteroids near resonance: the 4:1 gap and the 7:2 group 

      Grau Sánchez, Miguel; González Casado, Guillermo (1999-08)
      Article
      Accés restringit per política de l'editorial
      A comparative study of the evolution of the Sun–Jupiter–Asteroid system near the 4:1 and 7:2 resonances is performed by means of two techniques that proceed differently from the Hamiltonian corresponding to the planar ...

    • Estudi de la transformació de l'espai de color RGB a l'espai de color HSV 

      Grau Gotés, Maria Àngela; 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 ...

    • Note on the efficiency of some iterative methods for solving nonlinear equations 

      Grau Sánchez, Miguel; Noguera Batlle, Miquel; Díaz Barrero, José Luis (2015-11-02)
      Article
      Accés obert
      The e ciency of algorithms for solving nonlinear equations is a measure of comparison between di erent iterative methods. In the case of scalar equations two parameters are considered as it is well-known, but frequently ...

    • On a Moser-Steffensen type method for nonlinear systems of equations 

      Amat Plata, Sergio; Grau Sánchez, Miguel; Hernández Verón, Miguel Angel; Rubio, María Jesús (2016-12)
      Article
      Accés obert
      This paper is devoted to the construction and analysis of a Moser–Steffensen iterative scheme. The method has quadratic convergence without evaluating any derivative nor inverse operator. We present a complete study of the ...

    • On computational order of convergence of some multi-precision solvers of nonlinear systems of equations 

      Grau Sánchez, Miguel; Grau Gotés, Maria Àngela; 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 ...
