Métodos de punto interior para optimización cuadrática convexa con matrices no definidas positivas
(2009-02-25)
In this article a modification of the recursive algorithm of Cholesky is obtainedthat allows the factorization of Semi Definite Positive Matrices, even though theseare not positive defined, without increasing the computational ...

Nautelia: sistema automatizado para el ruteo náutico meteorológico
(2009-02-25)
For the captain of a ship, it is very important to have a proposal of the routethat allows him to reach the desired destiny as soon as possible, taking into accountweather conditions. In order to find such a route a former ...

An approach to ladder operators for the two-dimensional harmonic oscillator
An approach to ladder operators for the two-dimensional harmonic oscillator
(2009-02-25)
We show that elementary properties of associated Laguerre polynomials generatethe ladder operators for the harmonic oscillator radial wave function in two dimensions.Keywords: Harmonic oscillator, ladder operators, Laguerre ...

Elaboración de una metodología para la evaluación de la vulnerabilidad sísmica
(2009-02-25)
This work presents a methodology to assess the seismic vulnerability of a set ofstructures over a specific region. Using a simplified inference method we estimate theconditions of the structures in order to recommend either ...

Estimación bayesiana en la familia Pareto generalizada
(2009-02-25)
The generalized Pareto family of distributions with scale parameter > 0 andk form, has been used for modeling surplus over a given threshold, even though theparametric estimation in this family has some problems. In this ...
Conformally invariant differential operators and bilinear functionals in six dimensions
Conformally invariant differential operators and bilinear functionals in six dimensions
(2009-02-25)
We review how to construct the Paneitz operator in dimension four and the correspondingoperator in dimension six, by constructing symmetric bilinear differentialfunctionals that are conformally invariant.Keywords: Conformal ...
