Our understanding of the Universe has advanced tremendously in the past few decades, with General Relativity(GR) laying the ground for a successful model for the Universe, ΛCDM. However, there are still some fundamental ...
Atmospheric aerosols have played a key role in the development of the Earth’s atmosphere. Without atmospheric particles rainfall would be nonexistent and the climate would be very different. However, anthropogenic emissions ...
In this thesis, we will study the superfluidity of condensed atomic and photonic systems, through the manipulation of rotational states, such as vortices or persistent currents. We will study Bose-Einstein condensates both ...
This thesis is devoted to the study of the planar regime of N = 2 Lagrangian 4−dimensional superconformal field theories. In the first part of the thesis we study the matrix models that describe such theories upon performing ...
El trabajo presentado en esta tesis ha sido desarrollado en colaboración entre la empresa Francisco Albero S.A.U. (FAE) situada en L’Hospitalet de Llobregat (Barcelona, España) y el Institut de Recerca en Energia de Catalunya ...
[cat] En la actualitat les dades obtingudes amb instruments de teledetecció (mesures obtingudes a distància) formen una part essencial en l’àmbit de la meteorologia. Aquestes dades s’obtenen amb diversos sensors de tipus ...
The main goal of this thesis is to test the Standard Model (SM) of particle physics through the experimental analysis of rare processes, those that are suppressed in the SM. In particular, radiative b and rare strange ...
In this thesis, we explore different ways in which spacetime exhibits peculiar properties when subjected to the rules of quantum mechanics. These rules are naturally implemented at the level of semiclassical physics, where ...
This PhD thesis explores the quasi one dimensional Sb2Se3 absorber material and its application in substrate thin film solar cells in a SLG/Mo/Sb2Se3/CdS/i-ZnO/ITO configuration. The body of the thesis is introduced by a ...
This thesis is devoted to the study of radiation in generic conformal field theories in four dimensions. In the first part of the thesis we explain at the classical level the implications of considering accelerated ...
Una máxima que se plantea en la sociedad actual es la consecución de una mayor eficiencia en los procesos industriales, reduciendo factores como el peso, mejorando la respuesta con los ciclos de los materiales y sobretodo ...
Along this Thesis dissertation book, which is focused on the topic of Redox Flow Batteries, many efforts have been done in order to improve different aspects of the all-Vanadium Redox Flow batteries (VRFBs) technology, as ...
Chemical source localization (CSL) by autonomous robots has been a topic of research since the early 1990s and still today remains elusive beyond simple scenarios. It has numerous potential applications, such as the ...
Aparte del atractivo meramente matemático, el interés físico del estudio de los sistemas dinámicos con ligaduras reside en un hecho fundamental: sólo las teorías físicas cuya dinámica esté descrita por una lagrahgiana ...
The need of substituting the current energetic model by a system based on clean Renewable Energy Sources (RES) have gained more importance in the last decades due to the environmental issues related to the use of fossil ...
The bottom-up engineering of nanomaterials using solution-processing strategies is of particular interest for reducing cost and optimizing the performance of TE materials and devices. This thesis focuses on the development ...
TE devices have countless potential application, but their high manufacturing and material costs hamper their cost-effectiveness and limit their widespread implementation. To overcome these drawbacks, TE devices must be ...
The excessive consumption of non-renewable energy sources such as fossil fuels has lead the world to a global climate change, urging for new energy consumption habits together with developing cost- effective alternative ...
AIMS: We develop a new theoretical framework to generate Besançon Galaxy Model Fast Approximate Simulations (BGM FASt) to address fundamental questions of the Galactic structure and evolution performing multi-parameter ...
In this thesis we have presented a new method to search for tidal streams generated by globular clusters in the Gaia catalogue. This statistical method is based on the maximum likelihood technique to distinguish stream ...
