  • Estimación de los puntos de Fekete en la esfera unidad 

    Gesto Beiroa, José Manuel (Universitat Politècnica de Catalunya, 2003-10)
    Minor thesis
    Open Access
    Esta 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
    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 ...
  • Fekete points in non-smooth surfaces 

    Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2006-07)
    Article
    Open Access
    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 ...
  • 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 ...
  • Modelling of Jet Grouting and its interactions with surrounding soils 

    Gesto Beiroa, José Manuel; Gens Solé, Antonio; Arroyo Alvarez de Toledo, Marcos (2012)
    Conference report
    Restricted access - confidentiality agreement
    The versatility of Jet-Grouting as a soil improvement technique has made this procedure to be widely used in geotechnical engineering practice. In this work we discuss some aspects related to the THMC coupling phenomena ...
  • Numerical simulation of THMC phenomena associated with jet-grouting 

    Gesto Beiroa, José Manuel; Gens Solé, Antonio; Arroyo Alvarez de Toledo, Marcos (Research Publishing, 2012)
    Conference report
    Restricted access - publisher's policy
    A framework for the study of the jet-grouting hydration reaction and of the associated THMC interactions with the surrounding soils has been developed. In this work, we summarize the basic formulation that may be used for ...
  • Potential Theory for boundary value problems on finite networks 

    Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2006-07)
    Article
    Open Access
    We aim here at analyzing self-adjoint boundary value problems on finite networks associated with positive semi-definite Schrödinger operators. In addition, we study the existence and uniqueness of solutions and its ...
  • Regular boundary value problems on a path throughout Chebyshev Polynomials 

    Bendito Pérez, Enrique; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Gesto Beiroa, José Manuel (2006-08)
    Article
    Open Access
    In this work we study the different types of regular boundary value problems on a path associated with the Schrödinger operator. In particular, we obtain the Green function for each problem and we emphasize the case of ...
  • Smoothing of yield surfaces and a reformulation of multi-surface plasticity 

    Gesto Beiroa, José Manuel; Gens Solé, Antonio; Vaunat, Jean (Centro Internacional de Métodos Numéricos en Ingeniería (CIMNE), 2011)
    Conference report
    Open Access
    In this work we describe a procedure for the smoothing of non-regular yield surfaces and plastic potential functions. We also present several application examples corresponding to different well-known cases. Moreover, we ...
  • THMC modelling of jet grouting 

    Gesto Beiroa, José Manuel; Gens Solé, Antonio; Arroyo Alvarez de Toledo, Marcos (2013)
    Conference report
    Open Access
    A framework for the study of the jet-grouting hydration reaction and of the associated thermo-hydro-mechanical and chemical (THMC) interactions with the surrounding soils has been developed. In this work, we summarize the ...
