    • Construction and study of local linearization adaptive codes for ordinary differential equations 

      Sotolongo Aguiar, Alina; Jiménez Sobrino, Juan Carlos (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 ...

    • Funciones regulares en el plano y operadores de Nemytskii 

      Aziz, Wadie (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 ...

    • GNM-NIPALS: general nonmetric-nonlinear estimation by iterative partial least squares 

      Aluja, Tomás; González, Víctor Manuel (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, ...

    • Interstatis: the statis method for interval valued data 

      Corrales, David; Rodríguez Rojas, Oldemar (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 ...

    • K-finite objects and decidability 

      Acuña Ortega, Osvaldo (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.  

    • Location of police cars for public surveillance using two multicriteria models 

      García G., María J.; Hernández, Gilberto; Hernández R., José G. (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 ...

    • On the design of membranes with increasing fundamental frequency 

      González De Paz, Raúl B. (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 ...

    • The traveling salesman problem: a deterministic algorithm using tabu search 

      López, Erasmo; Salas Huertas, Oscar; Murillo Fernández, Álex (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 ...
