  • Simulation of two-fluid immiscible Stokes flows using hybrid nonconforming methods and geometrically unfitted meshes 

    Piccardo, Stefano (Universitat Politècnica de Catalunya, 2023-12-04)
    Doctoral thesis
    Open Access
    Covenantee:   École des Ponts ParisTech
    (English) We consider two-fluid problems involving immiscible Stokes fluids in contact and with surface tension at their interface. We develop, analyze, and compare two approaches for space discretization, the Hybrid ...
  • Rational-design of new candidates targeting bak and bombesin receptors in cancer 

    Vila i Julià, Guillem (Universitat Politècnica de Catalunya, 2023-11-22)
    Doctoral thesis
    Restricted access - confidentiality agreement
    (English) Cancer is the second leading cause of death globally, only behind cardiovascular diseases, being a major public health issue. Cancer comprises a wide group of diseases characterized by abnormal cell growth, which ...
  • Coercion-resistant cast-as-intended verifiability in electronic voting systems 

    Finogina, Tamara (Universitat Politècnica de Catalunya, 2023-10-02)
    Doctoral thesis
    Open Access
    (English) One of the most common fears regarding electronic voting is that a voting device will disregard the voter's intent and cast a different vote instead. An undetectable attack like that on a large scale will allow ...
  • Elliptic problems: regularity of stable solutions and a nonlocal Weierstrass extremal field theory 

    Urtiaga Erneta, Iñigo (Universitat Politècnica de Catalunya, 2023-07-04)
    Doctoral thesis
    Open Access
    (English) This PhD dissertation deals with qualitative questions from the theory of elliptic Partial Differential Equations (PDE) and integro-differential equations. We are primarily interested in a distinguished class of ...
  • Mathematical and computational modeling of flexoelectricity at fixed and moving interfaces, fracture surfaces and contact 

    Barceló Mercader, Jordi (Universitat Politècnica de Catalunya, 2023-09-08)
    Doctoral thesis
    Open Access
    (English) Flexoelectricity is a two-way coupling between strain gradient and polarisation or strain and polarization-gradient. Harnessing flexoelectricity as a functional property requires gradient engineering. This is a ...
  • High-performance computing fluid-structure interaction model of bioprosthetic aortic valve replacements 

    Oks, David (Universitat Politècnica de Catalunya, 2023-07-17)
    Doctoral thesis
    Open Access
    (English) Computational modeling and simulation (CM&S) provides a powerful cost- and time-efficient tool to access detailed mechanistic information of biomedical problems, which is not accessible in either clinical imaging ...
  • Mathematical and computational modeling of active cellular flows 

    Font i Reverter, Jordi (Universitat Politècnica de Catalunya, 2023-06-08)
    Doctoral thesis
    Open Access
    (English) During development, cellular tissues undergo dramatic reconfigurations as a result of organized flows driven by active forces. Depending on the system, cellular flows and active forces can be understood from a ...
  • Theory and computation of multiscale epithelial mechanics : from active gels to vertex models 

    Ouzeri, Adam Amine (Universitat Politècnica de Catalunya, 2023-06-14)
    Doctoral thesis
    Open Access
    (English) Epithelial monolayers perform a variety of mechanical functions, which include maintaining a cohesive barrier or developing 3D shapes, while undergoing stretches over a wide range of magnitudes and loading rates. ...
  • Flexoelectricity at surface instabilities and stress singularities 

    Mohammadi, Hossein (Universitat Politècnica de Catalunya, 2023-06-16)
    Doctoral thesis
    Open Access
    (English) The flexoelectric effect, the two-way linear coupling between strain gradient and electric polarization (direct flexoelectricity) or electric field gradient and strain (converse flexoelectricity) universally ...
  • Discrete operators and distances on subdivision networks 

    Monsó Burgués, Enrique P.J. (Universitat Politècnica de Catalunya, 2022-10-20)
    Doctoral thesis
    Open Access
    (English) The research we have carried out lies within the domain of diffusion problems for elliptic operators that are defined on discrete structures called networks, that are graphs that are capable of discriminating ...
  • Unstable motions in the three body problem 

    Paradela Díaz, Jaime (Universitat Politècnica de Catalunya, 2023-06-30)
    Doctoral thesis
    Open Access
    (English) The 3 Body Problem (3BP) models the motion of three bodies interacting via Newtonian gravitation. It is called restricted when one body has zero mass and the other two, the primaries, have strictly positive masses. ...
  • Mechanics of epithelial tissue subjected to controlled pressure 

    Chahare, Nimesh Ramesh (Universitat Politècnica de Catalunya, 2023-06-20)
    Doctoral thesis
    Open Access
    (English) Epithelial sheets form specialized 3D structures suited to their physiological roles, such as branched alveoli in the lungs, tubes in the kidney, and villi in the intestine. To generate and maintain these structures, ...
