• #### Método heurístico para particionamiento óptimo ﻿

(2009-02-20)
Many data analysis problems deal with non supervised partitioning of a data set,in non empty clusters well separated between them and homogeneous within the clusters.An ideal partitioning is obtained when any object can ...
• #### Métodos de optimización del stress. Comparaciones usando disimilitudes tipo intervalo ﻿

(2009-02-20)
By the use of simulated annealing it is defined the algorithm MDSI-SS for the optimization of Stress defined by Donoeux and Masson [6] for interval-type dissimilarities.On three data sets it is compared the value of stress ...

The main goal of the present work is to show a paralellism between the equationsin Physics and Mathematics, and some problems generated in another branch whichcould be called Mathematical Biology. The article is divided ...
• #### Sobre el problema inverso de difusión ﻿

(2009-02-20)
Infiltration is physically described in order to model it as a diffusion stochasticprocess. Theorem M-B 1 is enunciated; whose main objective is the inverse diffusionproblem. The theorem is demonstrated in the specific ...
