• Zero and coefficient inequalities for hyperbolic polynomials ﻿

(2006-03)
Article
Open Access
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 ﻿

(2013-01-01)
Article
Open Access
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 ...
• An improvement of Ostrowski root-finding method ﻿

(2006-02)
Article
Restricted access - publisher's policy
An improvement to the iterative method based on the Ostrowski one to compute nonlinear equation solutions, which increases the local order of convergence is suggested. The adaptation of a strategy presented here gives a ...
• Wave height data assimilation using non-stationary kriging ﻿

Article
Restricted access - publisher's policy
Data assimilation into numerical models should be both computationally fast and physically meaningful, in order to be applicable in online environmental surveillance. We present a way to improve assimilation for computationally ...
• Bayes linear spaces ﻿

(2010-12)
Article
Open Access
Linear spaces consisting of $\sigma$-finite probability measures and infinite measures (improper priors and likelihood functions) are defined. The commutative group operation, called perturbation, is the updating given by ...
