Una propuesta usando Restricciones para la toma de decisiones en la tolerancia a fallos en procesos de negocio
(Mondragón Unibertsitatea, 2009)
Cuando un proceso de negocio no obtiene el objetivo que se propone será necesario realizar una diagnosis y detección de errores, descubriendo qué servicios están funcionando de forma incorrecta para su sustitución. El ...

Algebra of derivations of Lie algebras
(Elsevier, 2001)
We show a method to determine the space of derivations of any Lie algebra, and in particular we apply this method to a special class of Lie algebras, those nilpotent with low nilindex. Most calculations have been supported ...

Classification of Gene Expression Profiles: Comparison of K-means and Expectation Maximization Algorithms
(IEEE Computer Society, 2008)
Biomedical research has been revolutionized by high throughput techniques and the enormous amount of data they are able to generate. In particular technology has the capacity to monitor changes in RNA abundance for thou ...

Logarithmic Comparison Theorem and some Euler homogeneous free divisors
(American Mathematical Society, 2005)
Let D, x be a free divisor germ in a complex manifold X of dimension n > 2. It is an open problem to find out which are the properties required for D, x to satisfy the so-called Logarithmic Comparison Theorem (LCT), ...

Tutte uniqueness of locally grid graphs
(Departamento de Matemáticas CINVESTAV, 2004)
A graph is said to be locally grid if the structure around each of its vertices is a 3 × 3 grid. As a follow up of the research initiated in [4] and [3] we prove that most locally grid graphs are uniquely determined by ...

A Hybrid Metaheuristic for Biclustering Based on Scatter Search and Genetic Algorithms
(Springer, 2009)
In this paper a hybrid metaheuristic for biclustering based on Scatter Search and Genetic Algorithms is presented. A general scheme of Scatter Search has been used to obtain high–quality biclusters, but a way of generating ...

Multi-Classification by Using Tri-Class SVM
(SpringerLink, 2006-02)
The standard form for dealing with multi-class classification problems when biclassifiers are used is to consider a two-phase (decomposition, reconstruction) training scheme. The most popular decomposition procedures are ...

The Interactions of Cyanobacterial Cytochromec6 and Cytochrome f, Characterized by NMR
(Elsevier, 2002)
During oxygenic photosynthesis, cytochromec6 shuttles electrons between the membrane-bound complexes cytochrome bf and photosystem I. Complex formation between Phormidium laminosum cytochromef and cytochrome c6 from ...

Instantaneous growth approximation describing the nanocrystallization process of amorphous alloys: A cellular automata model
(Elsevier, 2008-07)
A cellular automata simulation based on an instantaneous growth approximation is developed to model the nanocrystallization kinetics. In this frame, the time required for a nucleus to grow up to its maximum size is ...

Heisenberg superalgebras
(Taylor and Francis, 2009)
Heisenberg algebras are the only Lie algebras (g, [, ]) which verify [g, g] = Z(g) and dim(Z(g)) = 1, where Z denotes the center of the algebra. We classify nilpotent Lie superalgebras that verify the same algebraic ...
