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 ... -
Analysis of optimal control problems for the process of wastewater biological treatment
(2013-08-29)We consider a three-dimensional deterministic control model of the process of aerobic wastewater biotreatment. For this model, we formulate and solve two optimal control problems, each of which has a corresponding minimizing ... -
Análisis de las estructuras de opinión pública
(2009-02-18)En este trabajo se presentan los resultados de los análisis hechos a través de nueve años de investigación de las estructuras de la opinión pública en Costa Rica. La interpretación y los comentarios se hacen desde una doble ... -
Análisis de proximidades métrico usando búsqueda tabú
(2009-02-19)We apply tabu search (TS) in metric multidimensional scaling, obtaining good results comparable to those obtained with simulated annealing. A state in TS is a configuration of n points in a p dimensional space, and a ... -
Análisis de tablas múltiples con individuos cambiantes y variables fijas
(2009-02-18)En este artículo se presenta el método Statis cuando se observan las mismas variables en todos los instantes considerados, con individuos posiblemente cambiantes. Se demuestran varias propiedades de la infraestructura y ... -
Análisis de tablas múltiples de datos
(2009-02-18)Two methods for analyzing multiple data tables of the French Data Analysis school are presented: the Statis method and Multiple Factor Analysis. The types of data that can be trated by each methodology area analyzed and ... -
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
