An anisotropic microsphere-based approach for fiber orientation adaptation in soft tissue
(2011)
Article
Accés obertEvolutionary processes in biological tissue, such as adaptation or remodeling, represent an enterprising area of research. In this paper, we present a multiscale model for the remodeling of fibered structures, such as ... -
Combining size-preserving and smoothing procedures for adaptive quadrilateral mesh generation
(Springer, 2013)
Text en actes de congrés
Accés restringit per política de l'editorialIt is well known that the variations of the element size have to be controlled in order to generate a high-quality mesh. Hence, several techniques have been developed to limit the gradient of the element size. However, the ... -
Defining quality measures for validation and generation of high-order meshes
(Springer, 2013)
Text en actes de congrés
Accés restringit per política de l'editorialA procedure to quantify the distortion (quality) of a high-order mesh composed by curved tetrahedral elements is presented. The proposed technique has two main applications. First, it can be used to check the validity and ... -
Explicit parametric solutions of lattice structures with proper generalized decomposition (PGD): applications to the design of 3D-printed architectured materials
(2018-01-10)
Article
Accés obertArchitectured 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 ... -
Inserting curved boundary layers for viscous flow simulation with high-order tetrahedra
(Springer, 2013)
Comunicació de congrés
Accés restringit per política de l'editorialWe propose an a posteriori approach for generating curved meshes for viscous flow simulations composed by high-order tetrahedra. The proposed approach is performed in the following three steps: (1) generate a linear ... -
La generació d’una xarxa d’autobusos i l’assignació d’aquests a les línies: dos algorismes heurístics
(Universitat Politècnica de Barcelona. Centre de Càlcul, 1977-12)
Article
Accés obertL'article presenta un model de transport i dos algorismes que operen en el context d'aquest. El primer algorisme genera una xarxa d'autobusos, entenent una xarxa com un conjunt de línies, o bé en millora una de ja existent, ... -
Machine learning techniques for optimal worm-like motion
(Universitat Politècnica de Catalunya, 2023-05)
Treball Final de Grau
Accés obertEn un context de popularització de les tècniques d’Intel·ligència Artificial, aquest treball es proposa aplicar la versió més coneguda d’aquestes, les xarxes neuronals, per tractar comprendre la dinàmica del tipus de cuc ... -
Nonintrusive reduced order model for parametric solutions of inertia relief problems
(John Wiley & sons, 2021-08-30)
Article
Accés obertThe Inertia Relief (IR) technique is widely used by industry and produces equilibrated loads allowing to analyze unconstrained systems without resorting to the more expensive full dynamic analysis. The main goal of this ... -
On curving high-order hexahedral meshes
(Elsevier, 2015)
Comunicació de congrés
Accés obertWe present a new definition of distortion and quality measures for high-order hexahedral (quadrilateral) elements. This definition leads to two direct applications. First, it can be used to check the validity and quality ... -
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 ... -
Optimizing rock cutting through computer simulation
