    • A data-driven learning method for constitutive modeling: application to vascular hyperelastic soft tissues 

      González Ibáñez, David; García González, Alberto; Chinesta Soria, Francisco; Cueto Prendes, Elias (Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-01)
      Article
      Open Access
      We address the problem of machine learning of constitutive laws when large experimental deviations are present. This is particularly important in soft living tissue modeling, for instance, where large patient-dependent ...
    • Algebraic PGD for tensor separation and compression: an algorithmic approach 

      Díez, Pedro; Zlotnik, Sergio; García González, Alberto; Huerta, Antonio (2018-07)
      Article
      Open Access
      Proper Generalized Decomposition (PGD) is devised as a computational method to solve high-dimensional boundary value problems (where many dimensions are associated with the space of parameters defining the problem). The ...
    • Encapsulated PGD algebraic toolbox operating with high-dimensional data 

      Díez, Pedro; Zlotnik, Sergio; García González, Alberto; Huerta, Antonio (2019-11-28)
      Article
      Open Access
      In its original conception, proper generalized decomposition (PGD) provides explicit parametric solutions, denoted as computational vademecums or digital abacuses, to parametric boundary value problems. The PGD approach ...
    • Explicit parametric solutions of lattice structures with proper generalized decomposition (PGD): applications to the design of 3D-printed architectured materials 

      Sibileau, Alberto; García González, Alberto; Auricchio, Ferdinando; Morganti, Simone; Díez, Pedro (2018-01-10)
      Article
      Open Access
      Architectured materials (or metamaterials) are constituted by a unit-cell with a complex structural design repeated periodically forming a bulk material with emergent mechanical properties. One may obtain specific macro-scale ...
    • Mechanical and microstructural behavior of vascular tissue 

      Peña Baquedano, Estefania; García González, Alberto; Sáez Viñas, Pablo; Peña Baquedano, Juan Antonio; Cilla, Myriam; Martinez, Miguel Ángel (Elsevier, 2019)
      Part of book or chapter of book

      Accurate determination of the tissue response after vascular surgeries or pathologies in patients requires developing appropriate models of the organ or vessel under consideration. In this regard, combining experimental ...
    • Nonintrusive stochastic finite elements for crashworthiness with VPS/Pamcrash 

      Rocas, Marc; García González, Alberto; Larráyoz Izcara, Xabier; Díez, Pedro (2020-01-13)
      Article
      Open Access
      Crashworthiness analysis remains an important concern for the design of safety structures. In this context, uncertainties play an essential role in the response of a crash problem with non linear behavior. With this statement ...
    • On the modeling of patient-specific transcatheter aortic valve replacement: a fluid–structure interaction approach 

      Luraghi, Giulia; Migliavacca, Francesco; García González, Alberto; Chiastra, Claudio; Rossi, Alexia; Cao, Davide; Stefanini, Giulio; Rodríguez Matas, José Félix (Springer, 2019-09-01)
      Article
      Open Access
      Purpose Transcatheter aortic valve replacement (TAVR) is a minimally invasive treatment for high-risk patients with aortic diseases. Despite its increasing use, many influential factors are still to be understood and require ...
    • Optimitzación de la biosíntesis de nanocelulosa bacteriana por fermentación 

      García González, Alberto (Universitat Politècnica de Catalunya, 2017-10-03)
      Master thesis
      Open Access
      La cel·lulosa bacteriana és un biopolímer obtingut per fermentació amb diversos microorganismes, dels quals l’espècie més eficient en la producció és la Gluconacetobacter xylinus sucrofermentans. La principal diferencia ...
    • The effect of cell morphology on the permeability of the nuclear envelope to diffusive factors 

      García González, Alberto; Jacchetti, Emanuela; Marotta, Roberto (2018-07)
      Article
      Open Access
      A recent advance in understanding stem cell differentiation is that the cell is able to translate its morphology, i.e., roundish or spread, into a fate decision. We hypothesize that strain states in the nuclear envelope ...
