    • Creation of a Model of Pollutans Diffusion in Soil-Water System Using a Cellular Automata 

      Merino Castro, Glicina (2011-03-18)
      In this paper is presented a developed model for a pollutant diffusion in a soil-water system, for specific conditions in a real study area. A model that allows the observations of the pollutant flow in the soil-water ...
    • Curvas ROC y Vecinos Cercanos, Propuesta de un Nuevo Algoritmo de Condensación 

      Jiménez Padilla, Raquel; Cuevas Covarrubias, Carlos (2011-03-18)
      k-NN criteria are non parametric methods of statistical classificaction. They are accurate, versatile and distribution free. However,  their computational cost may be too expensive; especially for large sample sizes. We ...
    • Fuzzy Regression VS. Ordinary Least Squares Regression: Case Study 

      de los Cobos Silva, Sergio Gerardo; Goddard Close, John; Gutiérrez Andrade, Miguel Ángel (2011-03-18)
      The objective of this paper is to disseminate the technique of fuzzy regression and to give a practical example of its use. To this end, classical regression is compared to several fuzzy regression models on a problem ...
    • Heuristic for Solving the Multiple Alignment Sequence Problem 

      Mora Gutiérrez, Roman Anselmo; Ramírez Rodríguez, Javier; Elizondo Cortéz, Mayra (2011-03-18)
      In this paper we developed a new algorithm for solving the problem of multiple sequence alignment (AM S), which is a hybrid metaheuristic based on harmony search and simulated annealing. The hybrid was validated with the ...
    • Heuristics for Solving the Multiple Problem Identification of the Responses of Brain and Artificial Neural Networks in the Presence of Usual and Unusual Stimuli by Means of Kalman-Type Filters 

      Cardo, Romina; Corvalán, Alvaro (2011-03-18)
      We consider the problem of obtaining information about the recognition of logical inconsistencies with already imprinted patterns of a subnetwork of a neural network, both cerebral and artificially designed, by means of ...
    • Heuristics for the Robust Coloring Problem 

      Gutiérrez Andrade, Miguel Ángel; Lara Velázquez, Pedro; Lopez Bracho, Rafael; Ramírez Rodríguez, Javier (2011-03-18)
      Let $G$ and $\bar{G}$ be complementary graphs. Given a penalty function defined on the edges of $G$, we will say that the rigidity of a $k$-coloring of $G$ is the sum of the penalties of the edges of G joining vertices of ...
    • Integral Equations for the Aggregate Claim Amount 

      Pacheco González, Carlos G. (2011-03-18)
      In the context of insurance mathematics, we study the renewal properties of the so-called aggregate claim amount for the non-discounted and the discounted case. For these models, we set integral equations for the distribution ...
    • Minimal Reducts with Grasp 

      Mendez Gurrola, Iris Iddaly; Laureano Cruces, Ana Lilia; Ramírez Rodríguez, Javier (2011-03-18)
      The proper detection of patient level of dementia is important to offer the suitable treatment. The diagnosis is based on certain criteria, reflected in the clinical examinations. From these examinations emerge the limitations ...
    • Optimal Control of Pollution Stock through Ecological Interaction of the Manufacturer and the State 

      Grigorieva, Ellina V.; Khailov, Evgenii N.; Kharitonova, E. I. (2011-03-18)
      A model of an interaction between a manufacturer and the state where the manufacturer produces a single product and the state controls the level of pollution is created and investigated. A local economy with a stock pollution ...
    • Personnel Selection Based on Fuzzy Methods 

      Cañós, Lourdes; Casasús, Trinidad; Crespo, Enric; Lara, Tomás; Pérez, Juan C. (2011-03-18)
      The decisions of managers regarding the selection of staff strongly determine the success of the company. A correct choice of employees is a source of competitive advantage. We propose a fuzzy method for staff selection, ...
    • Regresion PLS y PCA como Solucion al Problema de Multicolinealidad en Regresion Multiple 

      Vega Vilca, José Carlos; Guzman, Josué (2011-03-18)
      We present and compare principal components regression and partial least squares regression, and their solution to the problem of multicollinearity. We illustrate the use of both techniques, and demonstrate the superiority ...
    • The Decreasing digits and the a, b, c Model: A Proposal for Handling Populations in Shelters 

      García G., María J.; Hernández R., José G.; Hernández G., Gilberto J. (2011-03-18)
      Happened a catastrophe, some one of the impacted population should their move from its homes, toward refuges or shelters. To guarantee the essential services in the shelter, it is necessary to know the population size that ...
