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 ...
Most of the efforts on the search and characterization of Earth-like exoplanets are currently focused on low mass stars. Some important properties related to the structure and processes in this type of stars are still ...
This project presents the study of luminescent devices and materials based on silicon for its use in the fabrication of an optical system that integrates light emitter, waveguide, and light sensor in a single chip obtained ...
The term light pollution refers to different harmful effects produced by artificial light sources. This phenomena affects observational astronomy, the flora and fauna of the species adapted to the natural cycles of light ...
The main goal of this thesis is to study the radiative decays produced in one of the four big detectors of LHC, LHCb, which focuses on the study of matter-antimatter asymmetry through b and c quarks. In particular, the ...
Biomolecular simulations have been widely used in the study of protein-ligand interactions; comprehending the mechanisms involved in the prediction of binding affinities would have a significant repercussion in the ...
The Gaia mission and its extensive catalogue of stars has marked the beginning of the Golden Age of Galactic dynamics. We have now access to the kinematics of more than a billion stars with which we can start ...
Nowadays, Nanotechnology is having an impact on practically every aspect of human life. It is a transformative technology that has influenced and will continue on electronics, computers, medicine, catalysis, energy, and ...
The goal of the present investigation is to examine the processing-structure-property relationships of multilayer graphene nanowall materials. Various plasma enhanced chemical vapor deposition (PECVD) processing parameters ...
[eng] This thesis focuses in the analysis of radative b-decays and rare strange decays, using data recorded by the LHCb, at the LHC during the Run 2 period. Two analyses are presented in the thesis, both flavour changing ...
The first confirmed detection of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found by radial velocity measurements in a four-day orbit around the nearby star 51 Pegasi by Mayor and ...
Spatial embedding and inherited metric constraints are a fundamental trait of biological neuronal circuits. However their role in shaping connectivity and dynamics has been often disregarded, with models of neuronal networks ...
This thesis studies Dark Energy, a central topic of Modern Cosmology, from different points of view. It covers from models and parametrizations to likelihood approximations for the observations of the Large Scale Structure ...
