A mimetic finite difference method using Crank-Nicolson scheme for unsteady diffusion equation
(2010-04-09)n this article a new mimetic finite difference method to solve unsteady diffusionequation is presented. It uses Crank-Nicolson scheme to obtain time approximationsand second order mimetic discretizations for gradient ... -
About the exact and asymptotic distribution of the Gini coefficient
(2010-04-09)In this paper we deal with the distribution of the Gini Concentration Index (G).We derive its exact sample distribution which is useful only for small sample sizesand basing on the classic results for L-statistics of Egorov ... -
Analysis and Design of the Knowledge Representation for the Implementation of a Distributed Reasoning
(2011-04-29)The representation of knowledge and the reasoning comprise fundamental parts of the design of an expert system. In the case under study the real world is represented by the different events that can arise in the operation ... -
Asignación de frecuencias en telefonía celular aplicando el problema de coloracion robusta
(2010-04-09)The Robust Coloring Problem (RCP) is a NP-Hard Problem for which fast andefficient heuristic algorithms has been developed. In this work we present as a PCRthe problem of assignment of frequencies for a cellphone grid. ... -
Clasificacion automática simbólica por medio de algoritmos genéticos
(2010-04-09)This paper presents a variant in the methods for clustering: a genetic algorithm forclustering through the tools of symbolic data analysis. Their implementation avoidsthe troubles of clustering classical methods: local ... -
Evaluation of air pollution control policies in Mexico City using finite Markov chain observation model
(2010-04-09)This paper proposes a Markov observation based model, where the transition ma-trix is formulated using air quality monitoring data for specific pollutant emissions,with the primary objective to analyze the corresponding ... -
Portfolio Optimization Using Particle Swarms with Stripes
(2011-04-29)In this paper it is consider the Portfolio Optimization Problem developed by Markowitz [11]. The basic assumption is that the investor tries to maximize his/her profit and at the same time, wants to minimize the risk. This ... -
Propiedades de un enfoque difuso para particionamiento con datos bimodales
(2010-04-09)It is presented a new fuzzy partitioning criterion for two-mode data and an algo-rithm is formulated for its optmization. We study the convergence properties of themethod. The method was tested on real data. It is ...
