Ribera Ponsa, Helena (Data de defensa: 2018-03-16)
In this thesis we study diffusion processes of nanoparticle evolution and develop appropriate models with the aim of being able to optimise their functions according to the needs of industry. Two distinct ...
Costa Miranda, Núria (Data de defensa: 2021-04-14)
This PhD thesis focuses on lattice-based cryptography and how to apply it to build post-quantum online voting systems. It is the result of the research done by the author at Scytl in close collaboration ...
Vegué, Marina (Data de defensa: 2018-03-23)
Structure is fundamental in shaping the types of computations that neuronal circuits can perform. Explaining the laws that determine the connectivity properties of brain networks and their implications ...
Dalfó Simó, Cristina (Data de defensa: 2007-12-19)
Normalment les grans xarxes d'interconnexió o de comunicacions estan dissenyades utilitzant tècniques de la teoria de grafs. Aquest treball presenta algunes contribucions a aquest tema. Concretament, ...
Barbero Liñán, María (Data de defensa: 2008-12-19)
Durant els darrers quaranta anys la geometria diferencial ha estat una eina fonamental per entendre la teoria de control òptim. Habitualment la millor estratègia per resoldre un problema és transformar-lo ...
Pujol Vázquez, Gisela (Data de defensa: 2004-11-19)
En aquesta tesi, presentem una solució per a dos problemes rellevants en la teoria de control: el problema del cost quadràtic garantit i el problema del control H∞, per a un cert tipus de sistemes. ...
Chrysokentis, Georgios (Data de defensa: 2019-04-03)
This thesis develops a large eddy simulation framework for engineering applications using the finite element method. It focuses on the numerical formulation, the wall modelling approach as well as the ...
Gatti, Francesca (Data de defensa: 2021-03-19)
Let E be an elliptic curve defined over the field of rational numbers and let f be the corresponding newform of weight 2. Let g,h be two weight one newforms whose nebentype characters are mutually ...
Muixí Ballonga, Alba (Data de defensa: 2020-11-30)
This thesis proposes a new computational model for the efficient simulation of crack propagation, through the combination of a phase-field model in small subdomains around crack tips and a discontinuous ...
Córdoba Pañella, Paula (Data de defensa: 2022-04-22)
This thesis aims at improving the convergence of iterative solvers, used for algebraic systems coming from the discretization of partial differential equations (PDE), in the context of large scale ...
