    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

    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 ...
