Characterization of symmetric M-matrices as resistive inverses
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2007-01-25)
Article
Accés obertWe aim here at characterizing those nonnegative matrices whose inverse is an irreducible Stieltjes matrix. Specifically, we prove that any irreducible Stieltjes matrix is a resistive inverse. To do that we consider the ... -
Computational cost of the Fekete problem
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2007-10-11)
Article
Accés obertWe present here strong numerical and statistical evidence of the fact that the Smale's 7th problem can be answered affirmatively. In particular, we show that a local minimum for the logarithmic potential energy in the ... -
Estimación de los puntos de Fekete en la esfera unidad
Gesto Beiroa, José Manuel (Universitat Politècnica de Catalunya, 2003-10)
Tesina
Accés obertEsta tesina se centra en el problema matemático de conseguir distribuir bien una cantidad cualquiera de puntos sobre la superficie de una esfera. Este problema admite multitud de variantes; nosotros estudiaremos tres de ... -
Estimation of Fekete points
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2005-05)
Article
Accés obertIn this paper we present a new method to estimate Fekete points on surfaces. Although our method works in a general setting, we concentrate on its application to the unit sphere because it is the prototype problem and ... -
Fekete points in non-smooth surfaces
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2006-07)
Article
Accés obertIn this paper we present a procedure for the estimation of the Fekete points on a wide variety of non-regular objects in $R^3$. We understand the problem of the Fekete points in terms of the identification of good ... -
Ground movement control in the construction of a new metro line in Barcelona
Gens Solé, Antonio; Mariano, Alessandra di; Gesto Beiroa, José Manuel; Schwarz, H (CRC Press, 2005)
Text en actes de congrés
Accés restringit per política de l'editorialGround movement control is of paramount importance in the construction of a new Metro line in Barcelona given the large diameter of the excavation and the need to cross heavily built areas. A variety of construction ... -
Kirchhoff indexes of a network
Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel; Mitjana Riera, Margarida (Elsevier, 2010-04-15)
Article
Accés restringit per política de l'editorialIn this work we define the effective resistance between any pair of vertices with respect to a value λ ≥ 0 and a weight ω on the vertex set. This allows us to consider a generalization of the Kirchhoff Index of a finite ... -
