Canonical realizations of Bondi-Metzner-Sachs–like symmetries in field theory
(Universitat Politècnica de Catalunya, 2024-07-08)
Doctoral thesis
Open Access(English) The BMS group appears as an infinite-dimensional group of isometries of asymptotically flat spacetimes first introduced by Bondi, Metzner, van der Burg, and Sachs in 1962. This group has gained interest recently ... -
Numerical optimisation of worm locomotion on frictional substrates
(Universitat Politècnica de Catalunya, 2024-07-18)
Doctoral thesis
Open Access(English) Optimal control theory provides a framework to determine optimal inputs for mechanical systems modeled as initial value problems. The resulting minimisation problem may be solved with known direct and indirect ... -
Poisson structures on moduli spaces and group actions
(Universitat Politècnica de Catalunya, 2022-10-03)
Doctoral thesis
Open Access(English) In this thesis, we study Poisson Structures on Moduli Spaces and Group actions. In particular, we focus on b^m-symplectic structures that can be seen both as symplectic structures with singularities and a particular ... -
Simulation of two-fluid immiscible Stokes flows using hybrid nonconforming methods and geometrically unfitted meshes
(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
(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
(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
(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
(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
(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
(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
(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
(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 ...
