Spatial interpolation of dry deposition using EOF models
(2009-02-19)Random processes are monitored over space and time by a network of stations distributed across a spatial region. Auxiliary information is often gathered not only at the stations but at other points across the region. The ... -
Special software for computing the special functions of wave catastrophes
(2015-01-01)The method of ordinary differential equations in the context of calculating the special functions of wave catastrophes is considered. Complementary numerical methods and algorithms are described. The paper shows approaches ... -
Stadis dual: software y análisis de datos reales
(2009-02-18)We present a computational implementation in MATHEMATICA of the dual Statis method and we use the method for the growth analysis of some kind of sugar cane.Keywords: multivariate date analysis, MATHEMATICA, multiple tables, ... -
Structural Change Analysis in Linear Regression Model.
(2010-07-02)Assuming that the observations are from normal distribution we obtain de distribution of the maximum likelihood ratio test if there is a change in the parameters at an unknown time and we find the maximum likehood estimators ... -
Submartingalas finitas, teoremas de convergencia y métodos no standard
(2012-03-29)Se examinan dos teoremas clásicos de convergencia de submartingalas en tiempo discreto, los de convergencia casi segura y en L^1, usando los métodos del análisis no standard. Se realiza para ello un estudio previo sobre ... -
SUPERIOR ORDER G -STRUCTURES
(2014-07-01)In this article we study the basic facts about superior order G-structures, then we show that the set of infinitesimally automorphisms of a geometric G-structure is a closed Lie group. -
Supplemental data acquisition tools for modeling environmental systems
(2009-02-20)The goal of our on-going research is to develop effective and reliable tools formodeling the environmental systems of the Gulf of Mexico. For example, our on-goingresearch into methodologies for the prediction of water ... -
Symmetry orbits and their data-analytic properties
(2013-08-29)The concept of data indexed by finite symmetry orbits is reviewed within the data-analytic framework of symmetry studies. Data decompositions are discussed in terms of canonical projections and Plancherel’s formulas, and ... -
TABU SEARCH WITH ASPIRATION CRITERION FOR THE TIMETABLING PROBLEM
(2015-01-01)The aspiration criterion is an imperative element in the Tabu Search, with aspiration-by-default and the aspiration-by-objective the mainly used criteria in the literature. In this paper a new aspiration criterion is ... -
Teoría de nudos geométricos e isotopía poligonal
(2009-02-19)The space of n-sided polygons embedded in euclidean three-space consists of a smoothmanifold in which points correspond to piecewise linear or “geometric” knots, while pathscorrespond to isotopies which preserve the geometric ... -
Term Structure of Interest Rates
(2012-03-02)The risk free rate on bonds is a very important quantity that allows calculation of premium values on bonds. This quantity of stochastic nature has been modeled with different degrees of sophistication. This paper reviews ... -
The Black-Scholes type financial models and the arbitrage opportunities
(2009-02-25)By using the conservation laws concept, we study certain financial models similar tothe Black–Scholes model. We show that without complement limitations such modelscan have two or more volatilities. This fact imposes several ... -
The BPS preconditioner on Beowulf cluster
(2009-02-27)This work presents the implementation on a Linux Cluster of a parallel preconditionerfor the solution of the linear system resulting from the finite element discretizationof a 2D second order elliptic boundary value problem. ... -
The Combinatorial ANT System for Dynamic Combinatorial Optimization Problems
(2012-03-22)In this paper is presented a distributed algorithm based on Ant System concepts,called Combinatorial Ant System, to solve dynamic combinatorial optimization problems. Our approach consists of mapping the solution space of ... -
The Decreasing digits and the a, b, c Model: A Proposal for Handling Populations in Shelters
(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 ... -
The Determinant of Matching Matrix in the Evaluation of Matching Polynomial
(2011-04-29)A characterization is given for graphs whose matching polynomial is the determinant of their matching matrices. The matching matrix is then modified and its relation with other graph polynomials is examined. -
The Hankel transform of causal distributions
(2012-03-29)In this note we evaluate the unidimensional distributional Hankel transform of \dfrac{x^{\alpha-1}_{+}}{\Gamma^{\alpha}},\dfrac{x^{\alpha-1}_{-}}{\Gamma^{\alpha}},dfrac{|x|^{\alpha-1}}{\Gamma^{\frac{\alpha}{2}}},dfrac{|x ... -
