A flexoelectric microelectromechanical system on silicon
(2016)
Article
Accés obertFlexoelectricity allows a dielectric material to polarize in response to a mechanical bending moment and, conversely, to bend in response to an electric field. Compared with piezoelectricity, flexoelectricity is a weak ... -
A high order finite element formulation for the simulation of 3D Magneto-Mechanical problems with application to MRI scanners
(2019)
Text en actes de congrés
Accés restringit per política de l'editorialTransient magnetic fields generated by the gradient coils in MRI scanners induce eddy currents in their conducting components, which lead to vibrations, imaging artefacts, noise and the dissipation of heat. Heat dissipation ... -
A multidimensional data-driven sparse identification technique: the sparse proper generalized decomposition
(2018-01-01)
Article
Accés obertSparse 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 ... -
A staggered high-dimensional Proper Generalised Decomposition for coupled magneto-mechanical problems with application to MRI scanners
(2020-10-01)
Article
Accés obertManufacturing new Magnetic Resonance Imaging (MRI) scanners represents a computational challenge to industry, due to the large variability in material parameters and geometrical configurations that need to be tested during ... -
Building a certified reduced basis for coupled thermo-hydro-mechanical systems with goal-oriented error estimation
(Springer, 2020-09)
Article
Accés obertA goal-oriented a-posteriori error estimator is developed for transient coupled thermo-hydro-mechanical (THM) parametric problems solved with a reduced basis approximation. The estimator assesses the error in some specific ... -
Case study: experimental characterization of noise and vibration sources in a refrigerator
(2021-11-01)
Article
Accés restringit per política de l'editorialThe sources of noise and vibration of a refrigerator are characterized by means of laboratory measurements. Three different elements are considered: compressor, evaporator fan, and condenser fan. Both the radiated acoustic ... -
Converse flexoelectricity yields large piezoresponse force microscopy signals in non-piezoelectric materials
(2019-03-20)
Article
Accés obertConverse flexoelectricity is a mechanical stress induced by an electric polarization gradient. It can appear in any material, irrespective of symmetry, whenever there is an inhomogeneous electric field distribution. This ... -
Discrete empirical interpolation for hyper-reduction of hydro-mechanical problems in groundwater flow through soil
(2023-04-10)
Article
Accés obertThe recent surge in the availability of sensor data and computational resources has fostered the development of technologies for optimization, control, and monitoring of large infrastructures, integrating data and numerical ... -
Flexoelectric MEMS: towards an electromechanical strain diode
(2016)
Article
Accés obertPiezoelectricity and flexoelectricity are two independent but not incompatible forms of electromechanical response exhibited by nanoscale ferroelectrics. Here, we show that flexoelectricity can either enhance or suppress ... -
Hierarchical micro-adaptation of biological structures by mechanical stimuli
(2013)
Article
Accés obertRemodeling and other evolving processes such as growth or morphogenesis are key factors in the evolution of biological tissue in response to both external and internal epigenetic stimuli. Based on the description of these ... -
Junctional and cytoplasmic contributions in wound healing
(2020-08-26)
Article
Accés obertWound healing is characterized by the re-epitheliation of a tissue through the activation of contractile forces concentrated mainly at the wound edge. While the formation of an actin purse string has been identified as one ... -
Manifold learning algorithms applied to structural damage classification
(2021-06-05)
Article
Accés obertA comparative study of four manifold learning algorithms was carried out to perform the dimensionality reduction process within a proposed methodology for damage classification in structural health monitoring (SHM). Isomap, ... -
On some aspects of the geometry of non integrable distributions and applications
(American Institute of Mathematical Sciences, 2018-12-01)
Article
Accés obertWe consider a regular distribution D in a Riemannian manifold (M, g). The LeviCivita connection on (M, g) together with the orthogonal projection allow to endow the space of sections of D with a natural covariant derivative, ... -

(2010-09)
Article
Accés restringit per política de l'editorialThe geometry of the set of generalized partial realizations of a finite nice sequence of matrices is studied. It is proved that this set is a stratified manifold, the dimension of their strata is computed and its connection ... -
On the use of the Bingham statistical distribution in microsphere-based constitutive models for arterial tissue
(2010)
Article
Accés obertConstitutive models for arterial tissue have been an active research field during the last years. The main micro-constituents of blood vessels are different types of cells and the extra-cellular matrix formed by an isotropic ... -
