GNM-NIPALS: general nonmetric-nonlinear estimation by iterative partial least squares
(2014-04-03)This paper develops GNM-NIPALS as an extension of the NM-PLS methods, which allows to quantify the qualitative variables of mixed data, by means of the reconstitution function using the first k principal com- ponents, ... -
Goal problems in gambling theory
(2009-02-18)A short introduction to goal problems in abstract gambling theory is given, along with statementes of some of the main theorems and a number of examples, open problems and references. Emphasis is on the finite-state, ... -
Grafos destinados al Análisis de datos Multivariante Condicionado por su Estructura
(2012-04-26)We present two new methods for the construction of graphs that can be used with descriptive techniques of Multivariate Data Analysis: a graph based in the chi-square distance and a graph based in strongly-connected components. ... -
Graph dominance by rook domains for Znp and Zn3 × Zm2 graphs
(2009-02-20)Described within is the problem of finding near-minimum dominating subsets of agiven graph by rook domains. Specifically, we study the graphs of the kind ZnpandZn3×Zm2and introduce a simulated annealing algorithm to compute ... -
Herramientas matemáticas para la valoración de la ampliación de una infraestructura portuaria
(2009-02-20)infraestructuraportuaria ya consolidada, que conlleva unas inversiones a largo plazo.Para ello hay que recurrir a medios de an´alisis capaces de recoger, en la medidade lo posible, la incertidumbre sobre la futura evoluci´on ... -
Heuristic analysis of a near optimal approximation algorithm for the determination of investment options
(2009-02-20)When cash becomes available in a company, there are several strategies that allowus to benefit from it. The problem is how much to invest, for how long, and using whichof the investment options in order to get the maximum ... -
Heuristic for Solving the Multiple Alignment Sequence Problem
(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
(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
(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 ... -
Hércules contra la Hidra y la muerte del Internet
(2011-04-29)Hercules killed the Hydra of Lerna in a bloody battle—the second of the labor tasks imposed upon him in atonement for his hideous crimes. The Hydra was a horrible, aggressive mythological monster with many heads and poisonous ... -
Implementation of LDG method for 3D unstructured meshes
(2012-07-01)This paper describes an implementation of the Local Discontinuous Galerkin method (LDG) applied to elliptic problems in 3D. The implementation of the major operators is discussed. In particular the use of higher-order ... -
El incremento multivariado
(2012-03-29)We develop and study a generalization to multivariate functions of the notion of increment, by mean of we can reproduce in several variables, many importants theorems of the Calculus in one variable. In particular, it is ... -
Indentificación de Fases de la Diabetes Espontánea de un Biomodelo Murino mediante Análisis Multidimensional de Datos
(2012-03-02)Biomodels used in the study of diabetes allow to evaluate genetic and environmental factors. Our aim was to characterize individuals of eSS, a genetically diabetic line of rats. We applied multivariate analysis, using the ... -
Indices of regularity and indices of randomness for m-ary strings
(2009-02-27)The notions “regularity index” and “randomness index” previously introduced forbinary strings (2-ary) have been modified slightly and generalized for m-ary strings(m = 2, 3, 4, . . .). These notions are complementary and ... -
Infinitely oscillating wavelets and a efficient implementation algorithm based the FFT
(2015-01-01)In this work we present the design of an orthogonal wavelet, infinitely oscillating, located in time with decay 1/|t|n and limited-band. Its appli- cation leads to the signal decomposition in waves of instantaneous, well ... -
Influence Factors in Private Investment in El Salvador
(2012-03-12)According to many empirical studies, one aspect that determines the foundations of economic cycles in the short and medium term is the investment of capital goods since it belongs to an aggregate demand and explains the ... -
Integral Equations for the Aggregate Claim Amount
(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 ... -
INTERACTIVE MULTIOBJECTIVE TABU/SCATTER SEARCH BASED ON REFERENCE POINT
