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 ...
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, ...
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 ...
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 ...
Location of police cars for public surveillance using two multicriteria models
Ubicación de radiopatrullas policiales para la vigilancia pública con dos modelos multicriterio
(2014-04-03)
The criminal boom in some Latin-American cities obliges the increment of patrols and policemen. Sadly they do not there sufficient vehicles to locate in all the places candidates. In the location of patrols, there are many ...
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.
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 ...
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 ...
On the design of membranes with increasing fundamental frequency
Sobre el diseño de membranas con frecuencia fundamental creciente
(2014-04-03)
By means of a relaxation approach, we study the shape design of a stiff inclusion with given area in a membrane in order to maximize its fun- damental frequency. As an eigenvalue control problem, the fundamental frequency ...
