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 ...

An algorithm for computing the first homology groups of CDGAs with linear differential
(Research Institute for Symbolic Computation, 1999)
We design here a primary platform for computing the basic homological information of Commutative Differential Graded Algebras (brie y, CDGAs), endowed with linear differential. All the algorithms have been implemented ...

Computing Cocycles on Simplicial Complexes
(Springer, 1999)
In this note, working in the context of simplicial sets [17], we give a detailed study of the complexity for computing chain level Steenrod squares [20, 21], in terms of the number of face operators required. This analysis ...

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 ...
