Least-perimeter partitions of the disk
(Real Sociedad Matemática Española, 2004)
In this work we study the isoperimetric problem of partitioning a planar disk into n regions of prescribed areas using the least-possible perimeter. We obtain the regularity conditions that must be satisfied by the ...

Descriptional Complexity of Tissue-Like P Systems with Cell Division
(Springer, 2009)
In this paper we address the problem of describing the complexity of the evolution of a tissue-like P system with cell division. In the computations of such systems the number of (parallel) steps is not sufficient to ...

Some advances in the research on Lie algebras
(2008)
The main goal of this poster, which is written in the form of a survey and tries to show some aspects of the research of authors on Lie algebras, is to pay homage to the memory of Pilar Pisón Casares, who was firstly teacher ...

Multiple Objective TSP based on ACO
(Universidad de Almería, 2003)
In this paper we present an Ant Colony Optimisation based algorithm to determine the Pareto set for the Multiple Objective Travelling Salesman Problem. Our results are then compared with the ones obtained with a genetic ...

Error correcting codes from quasi-Hadamard matrices
(Springer, 2007)
Levenshtein described in [5] a method for constructing error correcting codes which meet the Plotkin bounds, provided suitable Ha- damard matrices exist. Uncertainty about the existence of Hadamard matrices on all orders ...

Formulación de tipo Petrov-Galerkin de algunos métodos distributivos: Aplicación a las ecuaciones de Navier-Stokes
(2007-09)
En este trabajo estudiamos la resolución de las Ecuaciones de Navier-Stokes estacionarias mediante métodos distributivos no lineales. Formulamos estos métodos como métodos de tipo Petrov-Galerkin, en un contexto de ...

Obtaining Homology Groups in Binary 2D Images Using P Systems
(IEEE Computer Society, 2009)
Membrane Computing is a new paradigms inspired from cellular communication. We use in this paper the computational devices called P systems to calculate in a general maximally parallel manner the homology groups of ...

Analysis of the Parameters of Transfers in Rapid Transit Network Design
(Schloss Dagstuhl--Leibniz-Zentrum fuer Informatik, 2006)
The rapid transit network design problem consists of the location of train alignments and stations in an urban traffic context. The originality of our study is to incorporate into the location model the decisions about ...
