Aplicación de la búsqueda tabú en regresión no lineal
(2009-02-20)We implement the combinatorial optimization technique known as tabu search inthe parameter estimation problem in a given non linear model. For the generationof neighbors, the implementation is based on a discretization of ... -
Mmds and 2d scattering problem by cylindrical structure with piece-wise smooth boundary
(2009-02-20)An universal modification of the method of discrete sources (MMDS) was appliedfor solving 2D Dirichlet or Neumann boundary problem when the scatterer’s contour isa piece-wise smooth contour. The problems of accuracy, ... -
Formalización de una teoría de la mentalidad
(2009-02-20)We introduce a model based in Game Theory, and those used primarily in biology(evolutionary games) to understand history. We are interested in use the model tounderstand the last years of the colony of Costa Rica. We proved ... -
Deformaciones isométricas infinitesimales de una clase de superficies pegadas
(2009-02-20)In this work the sufficient condition of rigidity of a stuck 4-dimensional surface inthe Euclidean 6-dimensional space is demonstrated. This surface represents in himself,the product of Riemann of two surfaces, each one ... -
A formula for complex zonal polynomials of second order
(2009-02-20)A formula for complex zonal polynomials of second order is derived by solving aparticular partial differential equation.Keywords: Laplace-Beltrami operator, zonal polynomials, Hermitian matrix, Legendre’sdifferential equation. -
Rigidez de una superficie con puntos singulares
(2009-02-20)The infinitesimal isometric deformations of a type of surface with singular pointsare considered and a sufficient condition of rigidity of such surfaces is demonstrated.Keywords: Surface with singular points, Gauss formula, ... -
Generadores de números primos y factorizadores de números compuestos
(2009-02-20)The sequence of natural numbers presents itself as a multidimensional array. Twoproblems are solved on the basis of these arrays:a) distribution of prime numbers in multidimensional array,b) factoring of composite numbers.For ...
