Análisis digital. Una nueva técnica para la representación de funciones acotadas que, en un intervalo finito, satisfacen las condiciones de Dirichlet
(2009-02-19)A new technique is introduced for the approximation of any bounded function f(t) that satisfies Dirichlet's conditions in a finite interval, with a precision as high as wanted. Such approximation in obtained by adding n ... -
Análisis discriminante descriptivo: teoría, algoritmo y software
(2009-02-18)The objetive of this article is to present a computational implementation of the Descriptive Discriminant Analysis. We have developed some theoretical aspects in order to formulate an algorithm that was implemented using ... -
Análisis estadístico de datos categóricos ordenados
(2009-02-18)Ordered categorical panel data is modeled assuming an underlying continuous-time finite-space Markov chain. The tridiagonal form of the intensity matrix renders the implementation of the maximum likelihood method more ... -
Análisis evolutivo de la Opinión en Costa Rica: 1988-1991
(2012-03-29)En este artículo se utiliza el método Statis para analizar la evolución de la Opinión de los Costarricenses mayores de 18 años. Para tal efecto se usaron las encuestas anuales de opinión realizadas en el período 1988-1991, ... -
Análisis factorial de correspondencias intraclases ponderado
(2009-02-19)En este artículo se presenta una técnica de Análisis Factorial útil para el estudio de tablas de datos en las que existe una partición sobre el conjunto de individuos, definida de forma natural. Dicha técnica permite poner ... -
Análisis y síntesis de sistemas de ingeniería para la preparación y toma de decisiones bajo criterios múltiples
(2011-04-29)We present a methodology for the analysis and synthesis of systems dedicated to the preparation and decisions making under multiple objectives, as well as its application to engineering tasks. This methodology presupposes ... -
Análogos a Teoremas Tauberianos
(2011-04-29)We obtain some results similar to W. Rudin’s Tauberian Theorem, on singular integrals defined on bounded intervals. We also consider cases on which the Kernel is an oscillating function -
Anillos separables, de baer y pp-anillos
(2009-02-20)Keimel introduced the notion of proyectability in the class of lattice-ordered ringsand f-rings in [5]. Here we introduce a similar notion forgeting the lattice and orderedstructure of the ring and interpretating the ... -
Aplicación de la búsqueda tabú en regresión no lineal
(2009-02-20)We implement the combinatorial optimization technique known as tabu search inthe parameter estimation problem in a given non linear model. For the generationof neighbors, the implementation is based on a discretization of ... -
Aplicación del método de selección de propuestas a la descomposición de tareas discretas de optimización de gran complejidad
(2009-02-20)In the paper the method of Selection of Proposals and it generalisation, the problemof the organization of structures of conciliating decisions among interrelated systemsare studied. Focuses are offered for the optimal ... -
Application of a cognitive model of emotional appraisal to the board evaluation function of a program that plays chess
(2012-07-01)This paper describes the analysis and design of a cognitive emotional assesment model. This model is based on the goals looked for a chess player during a game. The model affects the output of the board evaluation function ... -
Aproximación fractal para semivariogramas freáticos
(2009-02-20)Hausdorff’s measure is integrated upon, and H¨older’s exponent is obtained as thecodimension DT ? D of the fractal in the Euclidian space in which it is immersed.This has resulted from the application of Daniell’s integral ... -
Artificial bee colony and particle swarm optimization for the estimation of nonlinear regression parameters
(2014-04-03)This paper shows the comparison results of ABC (Artificial Bee Colony) and PSO (Particle Swarm Optimization) heuristic tech- niques that were used to estimate parameters for nonlinear regression models. The algorithms were ... -
Artificial Neural Network Predictions of Water Levels in a Gulf of Mexico Shallow Embayment
(2012-03-01)Tide tables are the method of choice for water level predictions in most coastal regions. However, for many locations along the coast of the Gulf of Mexico, tide tables do not meet United States National Ocean Service (NOS) ... -
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. ... -
Asignación óptima de recursos
(2009-02-18)This work is on optimal assignation of resources. The proposed model is based on Net Flow Theory and here we give some indications for an efficient implementation of the model. -
Asymptotical analysis and Padé approximation in problems on diffusion-controlled cracks propagation
(2012-07-01)In this work, we consider the diffusion-controlled axisymmetric fracture in an infinite space, and half-space. An important example of diffusion-controlled fracture growth is given by hydrogen induced cracking. In metals, ... -
