  • Comparison of continuous and hybridizable discontinuous Galerkin methods in incompressible fluid flow problems 

    Fernández Méndez, Sonia (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
    Conference report
    Restricted access - publisher's policy
    A comparison of the computational efficiency between Continuous Galerkin (CG) methods, with Taylor–Hood approximations, and Hybridizable Discontinuous Galerkin (HDG) methods is presented for the solution of the incompressible ...

  • Coupling of continuous and HDG methods 

    Paipuri, Mahendra; Tiago, Carlos; Fernández Méndez, Sonia (International Centre for Numerical Methods in Engineering (CIMNE), 2018)
    Conference report
    Open Access
    A coupling strategy between hybridizable discontinuous Galerkin (HDG) and continuous Galerkin (CG) methods is proposed in the framework of second-order elliptic operators. The coupled formulation is implemented and its ...

  • Comparison of high-order continuous and hybridizable discontinuous {G}alerkin methods in incompressible fluid flow problems 

    Paipuri, Mahendra; Fernández Méndez, Sonia; Tiago, Carlos (2018-10-01)
    Article
    Open Access
    The computational efficiency and the stability of Continuous Galerkin (CG) methods, with Taylor–Hood approximations, and Hybridizable Discontinuous Galerkin (HDG) methods are compared for the solution of the incompressible ...

  • Classifying granular materials for feeding performance using experimental and numerical techniques 

    Torres Serra, Joel; Caba, Joan; Rodríguez Ferran, Antonio; Romero Morales, Enrique Edgar (2018)
    Conference report
    Restricted access - publisher's policy
    Flowability of powders and bulk solids is critical for the packaging industry in the selection and design of bulk material handling equipment. Nowadays, a variety of feeder systems are used for dosing operations in bagging ...

  • Hygroscopicity issues in powder and grain technology 

    Torres Serra, Joel; Romero Morales, Enrique Edgar; Rodríguez Ferran, Antonio (The Hong Kong University of Science and Technology (HKUST), 2018)
    Conference report
    Open Access
    The effect of hygroscopicity on flowability of powders and bulk solids with applications in the packaging industry is experimentally and numerically investigated. Firstly, four granular materials are tested at different ...

  • Smart helical structures inspired by the pellicle of euglenids 

    Noselli, Giovanni; Arroyo Balaguer, Marino; DeSimone, Antonio (2019-02)
    Article
    Restricted access - publisher's policy
    This paper deals with a concept for a reconfigurable structure bio-inspired by the cell wall architecture of euglenids, a family of unicellular protists, and based on the relative sliding of adjacent strips. Uniform sliding ...

  • Fully coupled numerical model of actin treadmilling in the lamellipodium of the cell 

    Kollepara, Kiran Sagar; Mulye, Paris D.; Sáez Viñas, Pablo (John Wiley & sons, 2018-12)
    Article
    Restricted access - publisher's policy
    Cells rely on an interplay of subcellular elements for motility and migration. Certain regions of motile cells, such as the lamellipodium, are made of a complex mixture of actin monomers and filaments, which polymerize at ...

  • Caracterización numérica y experimental de un sistema vibroacústico mediante "Advanced Transferer Path Analysis" 

    Cierco, Ester; Vicens Rodríguez, Pere; Aragonès Martín, Àngels; Arcas, Kevin; Poblet-Puig, Jordi; Magrans Fontrodona, Francesc Xavier; Rodríguez Ferran, Antonio (Sociedad Española de Acústica, 2018)
    Conference report
    Restricted access - publisher's policy
    ATPA (Advanced Transfer Path Analysis) is a method that allows knowing the noise paths and contributions of a vibroacoustic problem. It is clear that a good quantification of the less dominant contributions is essential ...

  • Arrival trade-offs considering total flight and passenger delays and fairness 

    Villardi de Montlaur, Adeline de; Delgado Muñoz, Luis (2018)
    Conference report
    Restricted access - publisher's policy
    This paper studies trade-offs between flight and passenger delays and fairness when assigning delay pre-tactically (on-ground at origin airport) due to reduced airport capacity. The paper also defines and analyses ...

  • A multidimensional data-driven sparse identification technique: the sparse proper generalized decomposition 

    Ibáñez Pinillo, Rubén; Abisset Chavanne, Emmanuelle; Ammar, Amine; González Ibáñez, David; Cueto Prendes, Elias; Huerta, Antonio; Duval, Jean Louis; Chinesta Soria, Francisco (2018-01-01)
    Article
    Open Access
    Sparse model identification by means of data is especially cumbersome if the sought dynamics live in a high dimensional space. This usually involves the need for large amount of data, unfeasible in such a high dimensional ...

  • Mechanical oscillations in biological tissues as a result of delayed rest-length changes 

    Muñoz Romero, José; Dingle, Monica; Wenzel, Manuel (American Institute of Physics (AIP), 2018-11-26)
    Article
    Open Access
    Oscillatory behavior in tissue biology is ubiquitous and may be observed in the form of either chemical or mechanical signals. We present here and solve a mechanical cell model that exhibits oscillations emerging from ...

  • Active superelasticity in three-dimensional epithelia of controlled shape 

    Latorre Ibars, Ernest; Kale, Sohan Sudhir; Casares, Laura; Arroyo Balaguer, Marino (Macmillan Publishers, 2018-11)
    Article
    Open Access
    Fundamental biological processes are carried out by curved epithelial sheets that enclose a pressurized lumen. How these sheets develop and withstand three-dimensional deformations has remained unclear. Here we combine ...
