      Article
      Open Access
      In 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 ...

      In 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)
      Conference report
      Restricted access - publisher's policy
      Ground 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
      Restricted access - publisher's policy
      In 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 ...
