    Canas Torres, José Antonio; Barbat Barbat, Horia Alejandro; Pujades Beneit, Lluís; Egozcue Rubí, Juan José; Sarrate Ramos, Josep (1991-12)
    Article
    Accés obert
    Numerical analysis applied to the Beznar dam accelerograms (longitudinal and transversal components) shows that the Fourier amplitude spectrum is a good approximation to the pseudo-velocity spectra. Thís fact makes possible ...

  • Zero and coefficient inequalities for hyperbolic polynomials 

    Rubió Massegú, Josep; Díaz Barrero, José Luis; Rubio Díaz, Pedro (2006-03)
    Article
    Accés obert
    In this paper using classical inequalities and Cardan-Viète formulae some inequalities involving zeroes and coefficients of hyperbolic polynomials are given. Furthermore, considering real polynomials whose zeros lie in ...
  • The normal distribution in some constrained sample spaces 

    Mateu Figueras, Gloria; Pawlowsky Glahn, Vera; Egozcue Rubí, Juan José (2013-01-01)
    Article
    Accés obert
    Phenomena with a constrained sample space appear frequently in practice. This is the case, for example, with strictly positive data, or with compositional data, such as percentages or proportions. If the natural measure ...
