Interstatis: the statis method for interval valued data
Interstatis: el método statis para datos de tipo intervalo
(2014-04-03)
The STATIS method, proposed by L’Hermier des Plantes and Escoufier, is used to analyze multiple data tables in which is very common that each of the tables have information concerning the same set of individuals. The ...
NONLINEAR FILTERS TO RECONSTRUCT ELECTROCARDIOGRAM SIGNALS
FILTROS NO LINEALES PARA RECONSTRUIR SEÑALES DE ELECTROCARDIOGRAMAS
(2014-07-01)
ECG signals have been used in cardiac pathology to detect disease heart. The main objective of this paper is to propose signal filtering techniques to reduce noise, extract information, to reconstruct the states and ...
Funciones regulares en el plano y operadores de Nemytskii
Regularized functions on the plane and nemytskii operators
(2014-01-01)
En este artículo mostramos que el espacio de las llamadas funciones regularizadas definidas sobre algún rectángulo del plano es un espacio de Banach. Más aún, bajo las hipótesis adecuadas damos condición necesaria ...
MATHEMATICAL MODEL FOR TOXIN TRANSPORT IN A MARINE FOOD CHAIN
MODELO MATEMÁTICO DEL TRANSPORTE DE UNA TOXINA EN UNA RED TRÓFICA MARINA
(2014-07-01)
Some cases of poisoning by consumption of contaminated fish, like the Ciguatera poisoning, occur unexpectedly and they are not easy to detect previously since the fish that carry the toxin do not have appearance and/or ...
GEODESIC DISTRIBUTION IN GRAPH THEORY: KULLBACK-LEIBLER-SYMMETRIC
DISTRIBUCIÓN GEODÉSICA EN TEORÍA DE GRAFOS: KULLBACK-LEIBLER-SIMÉTRICA
(2014-07-01)
Kullback-Leibler information allow us to characterize a family of dis- tributions denominated Kullback-Leibler-Symmetric, which are distance functions and, under some restrictions, generate the Jensen’s equality shown by ...
Artificial bee colony and particle swarm optimization for the estimation of nonlinear regression parameters
Colonia de abejas artificiales y optimización por enjambre de partículas para la estimación de parámetros de regresión no lineal
(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 ...
K-finite objects and decidability
Objetos K-finitos y decidibilidad
(2014-01-01)
We study the k-finite and decidable objects in an elementary topos. We prove some results concerning k-finite and decidable objects.
The traveling salesman problem: a deterministic algorithm using tabu search
El problema del agente viajero: un algoritmo determinístico usando búsqueda tabú
(2014-04-03)
We implement an algorithm corresponding to the Taboo Search method, called EraDeterministic, experimenting with the basic algorithm that ex- plores the search space and incorporating the diversification as strategy to ...
Construction and study of local linearization adaptive codes for ordinary differential equations
Construcción y estudio de códigos adaptativos de linealización local para ecuaciones diferenciales ordinarias
(2014-04-03)
The aim of this work is to construct adaptive integrators for ordinary differential equations based on the Local Linearization method. Different orders of the involved Padé approximation are considered and their effect ...
GNM-NIPALS: general nonmetric-nonlinear estimation by iterative partial least squares
GNM-NIPALS: Estimación general no métrica y no lineal por mínimos cuadrados parciales iterativos
(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, ...
