On a variational principle for shape optimization and elliptic free boundary problems
(2009-02-18)A variational principle for several free boundary value problems using a relaxation approach is presented. The relaxed Energy functional is concave and it is defined on a convex set, so that the minimizing points are ... -
Nuevas técnicas de particionamiento en clasificación automática
(2009-02-18)In this article there are exposed some new thechniques for hte search of global optima inthe partitioning problem in Cluster Analysis. With these thechniques the results are sensibly improved with respect to the traditional ... -
Análisis discriminante descriptivo: teoría, algoritmo y software
(2009-02-18)The objetive of this article is to present a computational implementation of the Descriptive Discriminant Analysis. We have developed some theoretical aspects in order to formulate an algorithm that was implemented using ... -
Casi-ortogonalidad y proximidad en L2 de martingalas pii en casi intervalos
(2009-02-18)It was introduced in [2] the notion of prOcess with independent increments in near-intervals (PII), establishing the existence of a decomposition into components with certain regularity properties. In this work we deepen ... -
Estimación no paramétrica de la densidad y de la regresión - previsión no paramétrica
(2009-02-18)We begin with a short wiew of non parametric estimation of density and regression; then we give details and interpretation of a forecasting method, called non parametric forecasting . We show different aspects, technical ...
