  • An approach to ladder operators for the two-dimensional harmonic oscillator 

    López Bonilla, José; Cruz Beltrán, L. (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 ...

  • Conformally invariant differential operators and bilinear functionals in six dimensions 

    Ugalde G., William J. (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 ...

  • Estimación bayesiana en la familia Pareto generalizada 

    Sánchez Gómez, Rubén (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 ...

  • La ecuación de Navier-Stokes y multifractales 

    Mercado Escalante, José Roberto (2009-02-25)
    There is currently no general theorem on the existence and unicity of solutions tothe Navier-Stokes equation, which describes the flow of a viscous and incompressiblefluid. This is an open problem at the international ...

  • Elaboración de una metodología para la evaluación de la vulnerabilidad sísmica 

    Aldama Ojeda, Alejandro; Gómez Soberón, Consuelo; Guillén López, Briseida (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 ...

  • Nautelia: sistema automatizado para el ruteo náutico meteorológico 

    Cordero Hernández, Yovany; Fernández Castillo, Karelia; Baguer Díaz-Romañach, Marta L.; Calnick, Anneris; Borrajeros, Israel (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 ...

  • Generalización de dos métodos de detección de conglomerados. Aplicaciones en bioinformática. 

    Rodríguez Corvea, Laureano; Casas Cardoso, Gladys M.; Grau Abalo, Ricardo; Pupo Meriño, Mario (2009-02-25)
    This paper presents a modification to the temporal disease clusters methods inorder to apply them to other sciences. Particular specifications are shown in Scanand temporal Grimson techniques. The original data are transformed ...

  • Métodos de punto interior para optimización cuadrática convexa con matrices no definidas positivas 

    Palencia F., Gonzalo; Hing C., Rosina; Rojas C., Mariledy; Medina S., Denysde (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 ...
