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 ...

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 ...

The General Set in the MCIM isotopic model
(Springer, 2005)
To obtain a bigger number of mathematical and physical applications of the Santilli's isotheory, the last studies have shown the neeed of analyzing isotopic models which use non associative laws. The main goal of this paper ...

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 ...

Single bend wiring on surfaces
(2002)
The following problem of rectilinear routing is studied: given pairs of points on a surface and a set of permissible orthogonal paths joining them, whether is it possible to choose a path for each pair avoiding all ...

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 ...

A consistent intermediate wave speed for a well-balanced HLLC solver.
(Gauthier-Villars, 2008)
In this work, we present a HLLC scheme modification for application to nonhomogeneous shallow-water equations with pollutant transport. This new version is related to the definition of a consistent approximation of the ...

Extending the notion of AT-Model for integer homology computation
(2007)
When the ground ring is a field, the notion of algebraic topological model (AT-model) is a useful tool for computing (co)homology, representative (co)cycles of (co)homology generators and the cup product on cohomology of ...

Rectifications of A-Algebras
(2007)
In this article, in the setting of connected DG-modules, we prove that, for any A -algebra M mi i≥1 , there is a chain contraction from a DG-algebra AM onto the DG-module M such that the A -algebra structure induced ...

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 ...
