  • A method for analyzing turbulence models 

    Grebene, V. N.; Ilyushin, B. B. (2009-02-19)
    In this article we introduce a concept based on the differential constraints methodto examine the closure procedure in Turbulence Models. We show how this conceptmay be applied to study the problem of interaction and mixing ...
  • Teoría de nudos geométricos e isotopía poligonal 

    Calvo Soto, Jorge Alberto (2009-02-19)
    The space of n-sided polygons embedded in euclidean three-space consists of a smoothmanifold in which points correspond to piecewise linear or “geometric” knots, while pathscorrespond to isotopies which preserve the geometric ...
  • Estabilizacíon del modelo poblacional de may a través de controles direccionales 

    Delgado Andrade, Víctor (2009-02-19)
    The May population model consider a satiate parameter over the predators andhas an unstable equilibrium state surrounded by a limit cycle. This work gives acontrol strategy driven to disturb the model in such way that the ...
  • Modeling genetic algorithms with interacting particle systems 

    Del Moral, P.; Kallel, L.; Rowe, J. (2009-02-19)
    We present in this work a natural Interacting Particle System (IPS) approach formodeling and studying the asymptotic behavior of Genetic Algorithms (GAs). In thismodel, a population is seen as a distribution (or measure) ...
  • Some properties and inequalities related to the kth inverse moment of a positive binomial variate 

    Arias López, Rodrigo; Garrido, José (2009-02-19)
     We present some known properties of bk(n, p) the kth inverse moment of a positive binomial variate. Additional properties of this function and new bounds are derived. Keywords:  Probability, statistics, life contingencies, ...
