Simulation of two-fluid immiscible Stokes flows using hybrid nonconforming methods and geometrically unfitted meshes
(Universitat Politècnica de Catalunya, 2023-12-04)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2023-11-22)
Tesi
Accés restringit per acord de confidencialitat(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
(Universitat Politècnica de Catalunya, 2023-10-02)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2023-07-04)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2023-09-08)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2023-07-17)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2023-06-08)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2023-06-14)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2023-06-16)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2022-10-20)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2023-06-30)
Tesi
Accés obert(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
(Universitat Politècnica de Catalunya, 2023-06-20)
Tesi
Accés obert(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, ...
