Testing Precessing Bar Models in Gaia Data
(Universitat Politècnica de Catalunya, 2020-10)
Projecte Final de Màster Oficial
Accés restringit per acord de confidencialitat
Realitzat a/amb: Universitat de BarcelonaIn this work we explore the origin of the Galactic warp, which is a deformation of the Galactic disc forming its typical S-shape when viewed edge-on. This novel theory is based on the idea of a small misalignment between ... -
The complexity of power indices in voting games with incompatible players
(Universitat Politècnica de Catalunya, 2023-01-23)
Projecte Final de Màster Oficial
Accés obertWe study the complexity of computing the Banzhaf index in incompatibility games. We show: 1) weak #P-completeness for computing the index when the incompatibility graph has very few maximal independent sets, 2) strong ... -
The devices, experimental scaffolds, and biomaterials ontology (DEB): a tool for mapping, annotation, and analysis of biomaterials' data
(2020-02-26)
Article
Accés obert
Realitzat a/amb: Institut de Bioenginyeria de Catalunya / Universitat de Barcelona / Barcelona Supercomputing CenterThe size and complexity of the biomaterials literature makes systematic data analysis an excruciating manual task. A practical solution is creating databases and information resources. Implant design and biomaterials ... -
The nonlinear optics of first-order phase transitions
(Universitat Politècnica de Catalunya, 2022-08-30)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Institut de Ciències Fotòniques (ICFO) / Universitat Autònoma de Barcelona / Universitat de BarcelonaNonlinear effects are used to specially broaden the spectrum by the interaction with a material at high intensities. Here we study nonlinear effects in a light induced first-order phase transition of a thin layer of VO2. ... -
Tip of the gender-based violence iceberg in Catalonia: Estimating the hidden part
(Universitat Politècnica de Catalunya, 2023-06)
Projecte Final de Màster Oficial
Accés obertOne in three women worldwide experience physical or sexual violence, mostly by an intimate partner. Despite the large number of complaints, it is suspected that they represent only a small portion of the cases occurring, ... -
Transferring filtered multiplicative structures in Homotopy Theory
(Universitat Politècnica de Catalunya, 2020-07)
Projecte Final de Màster Oficial
Accés restringit per acord de confidencialitat
Realitzat a/amb: Universitat de BarcelonaHomotopy Theory focuses in the study of algebraic structures up to homotopy, a notion that allows to study algebraic invariants of topological and geometric origin. A classical technique in Homotopy Theory, introduced by ... -
Twisted electrons as an imaging tool for probing chiral molecules in strong field ionization
(Universitat Politècnica de Catalunya, 2021-09-08)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Universitat Autònoma de Barcelona / Universitat de BarcelonaOrbital angular momentum (OAM) carried by vortex beams has seen an explosion of interest across fields and this is particularly true in attosecond physics. Given that twisted electrons have been shown to be sensitive to ... -
Ultra short laser pulse characterization device based on disordered nonlinear crystals
(Universitat Politècnica de Catalunya, 2017-10-27)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona / Universitat Autònoma de BarcelonaIn this project we build and test a compact and portable optical device for ultrashort pulse characterization. This setup allows the measurement of the pulse duration as well as its chirp parameter by using the so called ... -
Ultracold dipolar bosons trapped in atomtronic circuits
(Universitat Politècnica de Catalunya, 2022-07-19)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Universitat de Barcelona / Institut de Ciències Fotòniques (ICFO) / Universitat Autònoma de BarcelonaWe consider a ring-shaped triple-well potential with few polar bosons characterized by a long-range and anisotropic interaction. By diagonalizing the extended Bose-Hubbard Hamiltonian, that treats sites as macroscopic ... -
Ultrafast singlet fission dynamics in polymer-based thin-films measured by femtosecond transient absorption spectroscopy
(Universitat Politècnica de Catalunya, 2022-08-26)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona / Universitat Autònoma de BarcelonaSinglet fission is a photophysical process which converts an excited singlet state into two independent triplet states. This has attracted significant attention for photovoltaic devices due to the fact that more than one ... -
Unsupervised clustering for mining patterns in genomic dataset
(Universitat Politècnica de Catalunya, 2018-04-13)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Universitat de Barcelona / Universitat Rovira i Virgili / Barcelona Supercomputing CenterWe propose an architecture for detecting patterns in genomic rearrangements that may cause cancer. We use an unsupervised clustering method based on Kernel Density Estimation function and Graph Mining techniques for pattern ... -
