Mirza, Waleed Ahmad (Data de defensa: 2023-02-16)
(English)The structure and dynamics of important biological systems, ranging from cytoskeletal gels to tissues, are controlled by an interplay between activity, dissipation, nematic order, density, and geometry. In particular, ...
Tozzi, Caterina (Data de defensa: 2021-04-30)
Organelles are the smallest functional parts of eukaryotic cells. Among them, some are membrane-bound such as the nucleus, the endoplasmic reticulum, or the Golgi apparatus, each of them with essential biological functions. ...
Latorre Ibars, Ernest (Data de defensa: 2021-02-19)
Fundamental processes in development and physiology are determined by the three-dimensional architecture of epithelial sheets. How these sheets deform and fold into complex structures has remained unclear, however, because ...
Spiegel, Christoph (Data de defensa: 2020-07-03)
Arithmetic Combinatorics, Combinatorial Number Theory, Structural Additive Theory and Additive Number Theory are just some of the terms used to describe the vast field that sits at the intersection of Number Theory and ...
Escala Ribas, Alex (Data de defensa: 2017-07-21)
Electronic voting presents many challenges due to its multiple security requirements. Some of the challenges are related to guaranteeing voters' privacy and system's transparency, which are hard to satisfy simultaneously. ...
Roy, Mallika (Data de defensa: 2020-02-12)
This work is based on the family of groups Z^m x F_n, namely free-abelian times free groups, direct products of finitely many copies of Z and a finitely generated free group F_n. These are a special type of right-angled ...
Garrote López, Marina (Data de defensa: 2021-07-22)
Phylogenetics is the study of the evolutionary history and relationships among groups of biological entities (called taxa). The modeling of those evolutionary processes is done by phylogenetic trees whose nodes represent ...
Talaya López, Julià (Data de defensa: 2003-06-27)
El sistema NAVSTAR/GPS ha desenvolupat un paper molt important en les tècniques de posicionament cinemàtic geodèsiques, especialment en la determinació de la trajectòries per a la orientació de sensors aerotransportats ...
Gil-Muñoz, Daniel (Data de defensa: 2021-07-02)
We develop a method to compute a basis of the associated order in a Hopf Galois structure H of the ring of integers O_L of an extension of number or p-adic fields L/K. We state and prove a necessary and sufficient condition ...
Pellicer Sabadí, Marta (Data de defensa: 2004-09-17)
DE TESI DOCTORAL.<br/>Els sistemes formats per una molla fixa en un extrem i una massa rígida en moviment en l'altre, s'han modelitzat clàssicament mitjançant l'EDO de segon ordre mu''(t) + du'(t) + ku(t) = 0. Però aquest ...
Castillo Baliarda, Miquel (Data de defensa: 1988-05-07)
ESTUDIO DEL EFECTO DE LA MICROINFORMATICA EN EL PROCESO DE APRENDIZAJE DE LAS TECNICAS DE EXPRESION GRAFICA (T.E.G.). LA MICROINFORMATICA Y LOS PROGRAMAS DE CAD (DISEÑO ASISTIDO POR ORDENADOR) PUEDEN REPRESENTAR UN NUEVO ...
Rivero Salgado, Óscar (Data de defensa: 2021-02-12)
The main objective of this dissertation is the exploration of certain arithmetic applications of the Euler systems of Beilinson--Flach elements and diagonal cycles. Euler systems have been proved to be a very powerful tool ...
Yániz Fernández, Francisco Javier (Data de defensa: 2002-11-29)
El tratamiento intrínseco de cuestiones relacionadas con la Teoría de Control no lineal a través de la aplicación de técnicas propias de la geometría diferencial ha sido en los últimos años un tema de interés para muy ...
Blanco Fernández, Guillem (Data de defensa: 2020-04-16)
The main aim of this thesis is the study of the Bernstein-Sato polynomial of plane curve singularities. In this context, we prove a conjecture posed by Yano about the generic b-exponents of a plane irreducible curve. In ...
Planas Bahí, Arnau (Data de defensa: 2020-09-30)
This thesis explores classification and perturbation problems for group actions on a class of Poisson manifolds called $b^m$-Poisson manifolds. $b^m$-Poisson manifolds are manifolds which are symplectic away from a ...
Rubió Pons, Llorenç (Data de defensa: 2008-07-08)
En el marc de l'estudi de la cohomologia de les varietats algebraiques, i en particular en les aplicacions cohomològiques del teorema de resolució de singularitats d'Hironaka, utilitzem la tècnica de les hiperresolucions ...
Olivé Farré, Carme (Data de defensa: 2006-07-10)
L'objecte del nostre estudi és el sistema del pèndol simple amb una pertorbació ràpidament oscil·lant de període petit respecte el temps, però el paràmetre de pertorbació no serà necessàriament petit. El període de la ...
Olivar, Gerard (Data de defensa: 1997-07-01)
Esta tesis estudia el fenómeno del caos en las ecuaciones que modelan un convertidor buck con control PWM. Desde el punto de vista matemático, contribuye al estudio de los sistemas lineales a trozos tridimensionales, con ...
Finogina, Tamara (Data de defensa: 2023-10-02)
(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 ...
Montejano Cantoral, Amanda (Data de defensa: 2009-06-09)
A partir del problema de los cuatro colores se inicia el estudio de coloraciones en grafos; teoría que ha existido ya por más de 150 años, y se ocupa del problema fundamental de partir un conjunto en clases de acuerdo con ...
