The seven-triangle longest-side partition of triangles and mesh quality improvement
(Elsevier, 2008)
A new triangle partition, the seven-triangle longest-edge partition, based on the trisection of the edges is presented and the associated mesh quality improvement property, discussed. The seven-triangle longest-edge ...

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 ...

A theorem of H. Hopf and the Cauchy-Riemann inequality II
(Springer, 2007)
This is a sequel to “A theorem of H. Hopf and the Cauchy-Riemann inequality” [AdCT]. Here the result of the previous paper is extended (see the precise statement in Section 1 of the present paper) to surfaces in ...

The space of complete embedded maximal surfaces with isolated singularities in the 3-dimensional Lorentz-Minkowski space
(Springer, 2005)
We prove that a complete embedded maximal surface in L3 with a finite number of sin- gularities is an entire maximal graph with conelike singularities over any spacelike plane, and so, it is asymptotic to a spacelike ...

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 ...

Optimal Domains for L0-valued Operators Via Stochastic Measures
(Springer, 2007)
We study extension of operators T : E → L0([0, 1]), where E is an F–function space and L0([0, 1]) the space of measurable functions with the topology of convergence in measure, to domains larger than E, and we study the ...

An application of mixture distributions in modelization of length of hospital stay
(Wiley, 2008)
Length of hospital stay (LOS) is an important indicator of the hospital activity and management of health care. The skewness exhibited by this variable poses problems in statistical modeling. The aim of this work is to ...
