Order regularity for Birkhoff interpolation with lacunary polynomials
(2011-06-01)
Article
Accés obertIn this short paper we present sufficient conditions for the order regularity problem in Birkhoff interpolation with lacunary polynomials. These conditions are a generalization of the Atkinson-Sharma theorem. -
Spectral analysis of the Beznar dam accelerogram. Comparison with results in the northeastern of Spain
(1991-12)
Article
Accés obertNumerical 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
(2006-03)

Accés obertIn 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
(2013-01-01)
Article
Accés obertPhenomena 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 ...
