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 ...

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 ...

Separación y clasificación de puntos rojos y azules
(Universidad de Valladolid, 2007)
En este trabajo estudiamos el problema de determinar si dos conjuntos disjuntos de n puntos en el plano son separables mediante una estructura de 2-level tree, compuesta por una recta y dos semirrectas, y diseñamos ...

Incremental-Decremental Technique for Delineating Tunnels and Pockets in 3D Digital Images
(WikiCFP, 2009)
In this paper, we combine two complementary techniques for computing homol- ogy: Incremental Algorithm for computing AT-models (which consist of an algebraic set of data that provide, in particular, homological information ...

Solving the Independent Set problem by using tissue-like P systems with cell division
(Springer, 2009)
Tissue-like P systems with cell division is a computing model in the framework of Membrane Computing inspired by the intercellular communication and neuronal synaptics. It considers the cells as unit processors and the ...

“Coalgebra” Structures on 1-Homological Models for Commutative Differential Graded Algebras
(Springer, 2001)
In [3] “small” 1-homological model H of a commutative differential graded algebra is described. Homological Perturbation Theory (HPT) [7-9] provides an explicit description of an A∞-coalgebra structure (Δ1,Δ2,Δ3,...) of ...

On some partitioning problems for two-colored point sets
(Prensas de la Universidad de Zaragoza, 2009)
Let S be a two-colored set of n points in general position in the plane. We show that S admits at least 2 n 17 pairwise disjoint monochromatic triangles with vertices in S and empty of points of S. We further show ...
