Dynamics and bifurcations in a simple quasispecies model of unstable tumorigenesis
(Universitat Politècnica de Catalunya, 2014-10)
Bachelor thesis
Open AccessCancer is a complex disease and thus is complicated to model. However, simple models that describe the main processes involved in tumoral dynamics, e.g., competition and mutation, can give us clues about cancer behaviour, ... -
Estudio de la dinámica de un ecosistema marino
(Universitat Politècnica de Catalunya, 2016-05)
Bachelor thesis
Open Access
Covenantee: Institut de Ciències del MarLa aportación de los Sistemas dinámicos al estudio de modelos en Biología ha sido importante ya desde los primeros ejemplos asociados a dinámica de poblaciones: modelos depredador-presa, competición entre especies y muchos ... -
Existence of invariant tori in skew-product systems: A computer assisted approach
(Universitat Politècnica de Catalunya, 2020-01)
Master thesis
Open AccessThis work is a computer assisted approach to the study of invariant manifolds in skew-product dynamical systems. More specifically, the existence of an invariant tori under a quasi-periodic perturbation of our system. The ... -
Galoisian approach to supersymmetric quantum mechanics
(Universitat Politècnica de Catalunya, 2009-07-02)
Doctoral thesis
Open AccessEsta tesis versa sobre el punto de vista desde la Teoría de Galois Diferencial hacia la mecánica cuántica supersimétrica. El objeto principal considerado aquí es la ecuación deSchrödinger estacionaria no relativista, ... -
Interference of defective particles in the replication of RNA viruses with satellites
(Universitat Politècnica de Catalunya, 2018-09)
Bachelor thesis
Open AccessIn this project we have investigated a dynamical system describing the dynamics of a standard virus together with its defective interfering particles (DIPs) and a virus satellite. Our model is inspired in the hepatitis B ... -
Invariant curves for area preserving maps
(Universitat Politècnica de Catalunya, 2019-07)
Master thesis
Open AccessThis work aims to present tool of this approach is the so-called parameterization method, that produces a Newton-like iterative method to solve the invariance equation for an invariant torus, and the KAM theorem is a result ... -

Modelling attentional biases in bistable perception
(Universitat Politècnica de Catalunya, 2019-07)
Master thesis
Open AccessBinocular rivalry is a type of bistable perception phenomena that arises when the eyes are unable to combine ambiguous stimuli into a unique image. It promotes a competition process between the visual interpretations ... -

Nonlinear dynamics of replication modes in tunable deleterious fitness landscape
(Universitat Politècnica de Catalunya, 2017-07)
Bachelor thesis
Restricted access - author's decision
Covenantee: Centre de Recerca MatemàticaWe analyze a system of nonlinear ordinary differential equations describing the intracellular amplification dynamics of viral RNA genomes. The replication modes considered range between two extremes given by the so-called ... -

(Universitat Politècnica de Catalunya, 2016-07)
Bachelor thesis
Restricted access - author's decisionNow a days mathematics can be used for many different purposes or topics, and every day new fields to be applied are found. One of this fields, which is becoming more and more popular, is financial mathematics. This thesis ... -
Parameter estimation for a mathematical model predicting the COVID-19 spread in the Àrea Metropolitana de Barcelona
(Universitat Politècnica de Catalunya, 2020-07)
Master thesis
Open AccessEpidemiology is the medical discipline in charge of sudying the dynamics of a disease in a given population; particularly, we are interested in human infectious diseases. In the 18th century, with Daniel Bernouilli, a new ... -
Phase-responsiveness transmission in a network of quadratic integrate-and-fire neurons
(Universitat Politècnica de Catalunya, 2020-01)
Bachelor thesis
Open AccessIn the study of the dynamics of neuronal networks, it is interesting to see how the interaction between neurons can elicit different behaviours in each individual one. Moreover, this can lead to the population exhibiting ... -
Population modelling for dormancy cancers
(Universitat Politècnica de Catalunya, 2020-07)
Bachelor thesis
Open AccessImmunotherapy is a type of cancer treatment that boosts the natural defenses of the body to fight cancer without damaging normal cells. Many scientists have shown interest in developing a mathematical model that simulates ... -
Using heterogeneity for obtaining the Medial Axis Transform of natural images
(Universitat Politècnica de Catalunya, 2018-05)
Bachelor thesis
Open AccessFrom Blum's Medial Axis Transform, that obtains the skeleton of binary images by joining the centers of all maximal inscribed disks in the shape, the AMAT was developed. The Appearance-MAT is a method that aims to compute ... -
Warmer temperatures and their effect on East-African malaria
(Universitat Politècnica de Catalunya, 2020-07)
Master thesis
Open AccessMalaria has been an issue worldwide for a long time, having a huge social, economic, and health burden. This disease occurs mostly in tropical and subtropical areas of the world, in countries where the levels of poverty ...
