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 ... -
Location of police cars for public surveillance using two multicriteria models
(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 ... -
The traveling salesman problem: a deterministic algorithm using tabu search
(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 ... -
Interstatis: the statis method for interval valued data
(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
(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, ... -
On the design of membranes with increasing fundamental frequency
(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 ... -
Funciones regulares en el plano y operadores de Nemytskii
(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 ... -
Construction and study of local linearization adaptive codes for ordinary differential equations
(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 ... -
K-finite objects and decidability
(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.
