Summary
The global climate change being experienced has prompted various governments to take measures to mitigate its effects. One of these measures has been the implementation of an energy transition, aimed at reducing greenhouse gas emissions and dependence on fossil fuels. This will be achieved through the progressive increase in the proportion of renewable energy sources in the energy mix. This rise in renewable energy entails the need to adapt the electrical transmission network to achieve the established goals for the energy transition in Spain. However, this involves a series of associated technical difficulties that must be addressed. That's why this Master's Thesis examines the proposed objectives in Spain, the current state of the transmission network, the technical challenges to be addressed, the forecast of future renewable energy projects, and the transmission network planning developed by Red Eléctrica. After analyzing all these points, the weaknesses in the current transmission network and the level of adequacy of the measures taken are determined.

Summary
To comply with the Sustainable Development Goals (SDGs), international regulations have been created such as the Renewable Energy Directive (RED) and the International Sustainability and Carbon Certification scheme (ISCC) that allow companies to acquire a certificate that indicates that their processes and products are sustainable and are intended to meet the SDG. This master's thesis presents an investigation into the perception of companies that currently have an ISCC scheme certificate and how they act in productive development within the different areas of the Colombian territory. For this, the research was approached from a mixed approach (qualitative and quantitative) which allowed the application of an information collection instrument where the results were correlated with information and research cited in this work which has been done in the last 10 years within of the country all in order to conclude if the ISCC scheme is a promoter of environmental awareness or, failing that, it is putting natural resources at risk. “The results were surprising.”

Summary
The increasing use of electric vehicles has led to a demand for new specialized lubricants tailored for this type of vehicle with the goal of enhancing its efficiency and prolonging their lifespan. Innovation in this field involves the incorporation of nanoparticles as an alternative to conventional additives in lubricants. This Master's Thesis examines the effects of adding nanoparticles of titanium carbide MXene (Ti3C2Tx) and calcium carbonate (CaCO3) to a base oil (PAO8) in concentrations of 0.05 wt%, 0.10 wt%, 0.15 wt%, and 0.20 wt%. The study addresses the synthesis of these nanoparticles, their characterization, the formulation of nanolubricants, and the analysis of their temporal stability. Tribological characterization is also carried out, including the friction coefficient, wear parameters, and roughness of worn surfaces compared with the base oil. Finally, an analysis of the lubrication mechanisms occurring with the application of these nanolubricants is proposed, contributing to a deeper understanding of the processes involved.

Summary
The present final master's thesis was carried out with the aim of developing a Sustainable Rural Community based on the study of three energy communities in the towns of Armallones, Poveda de la Sierra, and Zaorejas, municipalities belonging to Guadalajara, Spain. Likewise, different alternatives based on community tourism were sought, achieving local growth. To do this, the corresponding sizing of the energy communities was carried out through different programs such as iHOGA, HelioScope, and PVGIS to conduct an adequate economic analysis and thus achieve significant savings in the energy bills of both the town halls and the participating residents in this legal form. It is important to mention that three months after presenting the initial project carried out during rural campus practices, it was approved on January 24th of the current year. Similarly, for this work, a schedule was created considering the different places of interest belonging to the Alto Tajo Community to support the various local initiatives, generate attachment to the villages, create employment, and promote greater awareness of the towns to attract more tourists to the area and, in turn, achieve a social, environmental, and economic balance.

Summary
In this work, the modeling of a design for an off-grid green hydrogen production plant located at Sabón industrial plot (A Coruña) is presented. This industrial plot, which hosts large business consortia that are very sensitive to decarbonization, has good levels of both solar and wind resources. Considering a reference energy system consisting of a PEM type electrolyzer system of 1MW (commercial model) of power, powered by a wind-solar hybrid system. To ensure independence from the electrical grid, a lithium-ion battery accumulation system is considered. The modeling tool used in the work, HOMER, has made possible to verify the technical and economic feasibility of the proposal. The optimal proposal, consisting of a hybridized plant with 3.8 MWp of solar power, 3 MW of wind power and 4 MW of storage capacity, would be able to generate roughly 540 kg/h of green hydrogen. Taking into consideration the total estimated cost of the project (10.86 million dollars (M$)), the gross price of the hydrogen produced can be estimated at approximately 2.2045 $/kg. To evaluate the economic sustainability of the project, both the direct sale of the hydrogen and oxygen produced, and the excess of renewable electricity production are proposed. Under these conditions, an IRR of 24% is obtained for 25 years of lifetime for the project and the total investment would be recovered in 5 years. This research project was chosen as a national finalist for the 15th edition of the EDPR University Challenge competition organized by the energy company EDP Renewables and was presented and exhibited among the 5 best projects of the 2023 competition in the city of Madrid on October 25th. 2023, representing the University of Santiago de Compostela.

Summary
The study conducts an analysis of the set-up proposed by the Foundation Ciudad de la Energía (CIUDEN) to assess the response of polycrystalline panels with UMG technology concerning resistivity. Factors that may influence the data analysis are identified. The potential influence of reflection on the vertical panel is demonstrated. Possible shadow influences on the set-up and their respective affected time periods are detected. The coefficients of correlation for global radiation and DF among different powers are analyzed to evaluate the progress of the research. The results are used to create linear regressions that allow the detection of fluctuations in behavior. Finally, based on the findings of the study, proposals for the continuation of experimentation are put forth, along with the selection of the most suitable candidates for the next phase.

Summary
Green hydrogen production has been experimenting an important support from industries and governments in the last few years, to become the principal solution for climate change. The European Union alone is planning to invest around 500 billion euros in green hydrogen production projects to scale its capacity from 0.1 GW to 40 GW by the end of 2030 [1]. This study will focus on four simulations of a 5MW alkaline water electrolyzer pilot plant for green hydrogen production. The aim of these simulations is to understand the consumption of raw materials (water and electricity), efficiency, costs, and other essential requirements for the eventual production of green hydrogen and its subproducts. The results will be used as a starting point to develop a discussion on the requirements and future of green hydrogen technology, as well as the importance of hydrogen as one of the main options to achieve a future with net zero CO2 emissions. The production of ammonia and urea is also reviewed as two important subproducts that can be used to give hydrogen an extra value and help to decarbonize two of the main intensive CO2 industrial processes. These kinds of projects present better financial conditions and could be used as the basis for improving technology and creating green hydrogen markets, which eventually reduce prices enough to compete with traditional carbon-based hydrogen production.

Summary
The search for energy alternatives and the improvement of process and equipment is seeking to optimize the way energy is consumed at a general level, for which numerous sensors are used to establish regulated consumption over time, in addition to promoting self-generation. In order to take advantage of the remaining energy, use is made of different transducers, capable of transforming a generation source to another usable by electronic equipment. Since such devices typically produce very low power and voltage, it is necessary to implement intermediate circuits in order to condition the output values to be useful for the devices to be powered. In line with this objective, the present work exposes the design of a step-up DC-DC converter circuit for ambient energy harvesting circuits, starting from very low input voltage values (as low as 57 mV).

Summary
The 2030 Agenda and specifically the 17 Sustainable Development Goals (SDGs) are measures created by the UN to move towards the sustainable development of territories, dealing with problems such as poverty, climate change or economic and social inequalities. Almost five years before the deadline proposed by this entity, we find that many countries, cities and even companies do not apply what is stated in this Agenda. This is why this Master's Thesis sets out a sustainable development guide for the Iniciativa Prato_DO entity, which aligns its activities with those included in the SDGs and in the Agenda 2030 itself. One of the main problems is how ambitious the objectives proposed by UN are, so in this thesis we will focus on creating specific actions within the scope of the company's work, paying special attention to the creation of a follow-up plan, in order to ensure compliance with all the actions mentioned. All the measures and actions presented below are mainly aimed at improving the quality of life in the city of Viveiro while moving towards its sustainable development.

Summary
This research is a proposal to transform the Alto Tajo Community (Guadalajara), in particular the villages of El Recuenco, Peñalén and Huertapelayo, in a sustainable community encouraging the rural development and cooperating with the Sustainable Development Goals (SDGs). To accomplish it, 3 energetic communities are designed, all based on photovoltaic installations for collective self-supply. iHOGA, PVGIS, and HelioScope were the programs used. In order to provide 100 % energy for each Townhall and 50 % extra for each cooperative, 152 photovoltaic modules were designed for El Recuenco, 210 for Peñalén, and 106 for Huertapelayo. Virtual batteries are suggested as the energy storage system. The main goal is to reduce electricity bill costs and promote autonomy regarding large suppliers. Besides, climbing is proposed as an activity in order to encourage local, active and sustainable tourism. Creating jobs and setting population in Alto Tajo is the aim of the project in the medium long term.

Summary
The AIRES system is a set of programs that do MonteCarlo simulations of air showers of secondary particles produced by the interaction of high-energy cosmic particles with the Earth's atmosphere. Specifically, inclined air showers, those that reach ground with zenith angles with respect to the vertical $\theta$ higher than 60º, are characterized by the dominance of the muonic component which is accompanied by an electromagnetic halo produced mainly by decay of muons and muon interactions. The study of this type of air showers depends significantly on the hadronic interaction model used. The objective of this work is to characterize the densities of particles detected at ground using the most recent hadronic interaction models that arise from the latest results obtained in research carried out at the LHC (QGSJET-II-04, SIBYLL 2.3d and EPOS LHC) and compare the results obtained with the research carried out by I. Valiño et al. with the old hadronic model QGSJET01.

Summary
This work explores current-current deformations in two-dimensional Conformal Field Theories (CFTs), a critical area in theoretical physics with applications in string theory and different phenomena in condensed matter physics. The study delves into the conformal group, representations in various dimensions, and the specific richness of two-dimensional conformal invariance. It extends to an in-depth examination of T-duality and TsT transformations in $\sigma$-models, emphasizing integrably-marginal deformations. Particular attention is given to the $SL(2,\mathbb{R}) \times SU(2)$ Wess-Zumino-Witten model, analyzing the computation of the third-order correction in the two-point function and the marginality of current-current deformations. This work aims to contribute to the understanding of how certain deformations impact the conformal symmetry, this study is also related to the construction of new supergravity backgrounds, which is crucial for advancements in the $AdS/CFT$ correspondence.

Summary
The 12Li nucleus is an unstable system that lies beyond the neutron drip line (Sn less than 0). Its study constitutes a way to explore open quantum systems far from the valley of stability. Until now, the 12Li nucleus has been studied using the invariant mass technique with solid/liquid targets. This technique presents problems associated with the difficulty of measuring the neutrons resulting from the decay with sufficient precision. Due to this, an experiment was proposed to study the excited states of 12Li using the missing mass technique with the ACTAR-TPC gaseous active target. With this new experimental device, it is expected to increase the resolution in the excitation energy measurement and to improve the statistics of the experiment. This work consisted of performing a complete simulation of the experimental device and the transfer reaction under study, using the CERN analysis package ROOT. In the presented work, the ACTAR-TPC detector was characterized as realistically as possible. In the performed simulation, the different sources of uncertainty were implemented and their impact on the results was studied; specifically, on the excitation energy spectrum. Finally, from the simulations, the final observables of the experiment were obtained: excitation energy and the differential cross sections of the different simulated states.

Summary
This Master's Thesis aims to explore various fundamental consequences of the well-known BPS Skyrme model in Nuclear and Particle Physics. Firstly, an introduction to the Skyrme model is provided, particularly focusing on how the atomic nucleus is modeled within this theory. Secondly, the necessity of the BPS model and its main qualitative advantages are justified. The solutions to the associated equations of motion, the (classical) Skyrmions, are calculated, and we obtain a classical expression for their energy and radius. Thirdly, the quantization of the Skyrme field is studied by introducing rotational and isorotational degrees of freedom. This leads us to calculate the inertia tensors of isospin, spin, and mixed nature. It enables the calculation of the nucleus's energy due to the contributions from spin and isospin and allows us to analyze the limitations of the axial ansatz that we have assumed. Lastly, we compute the conserved currents associated with two important transformations: vector and axial-vector. Obtaining these currents in Skyrme theory is necessary for modeling the nucleus's effect (the form factor) in interactions between nuclei and particles in electroweak theory. First we compute the classical currents using Noether's theorem, followed by incorporating the quantization previously developed for the energy. The electroweak currents are linear combinations of these currents, modeling the electroweak interaction between Standard Model particles and the Skyrmion.

Summary
The population phenomenon in Spain involves the concentration of the population in the outer cities and on the coast, causing population decrease in rural areas. Alto Tajo´s Mancomunidad represents one of the areas most affected by the above phenomenon. Its population density is 0,87 inhabitants/km2, which is a problem of great proportions if we consider that the demographic parameter of 10 inhabitants/km2 is the prelude to the beginning of the neglect and social disarticulation of the populations. In order to improve the economic activity of the area and fix the population, the analysis of creating energy communities through the installation of photovoltaic systems was developed in the towns of Arbeteta, Peralveche, Villanueva de Alcorón and Villar de Cobeta. In addition, the use of wood from the area to produce pellets and options to promote the region's own trades were also considered. Regarding the energy communities, it would be necessary to create 7: One per community in Peralveche and Villar de Cobeta, 2 in Arbeteta and 3 in Villanueva de Alcorón. The investment for the installation of the photovoltaic systems in the 4 villages would be around 364,700 euros and the payback period for the investment would be between 11 and 15 years. Regarding the installation of a pellet production plant, a production of 10.000 mt pallets/year was estimated, and taking as a basis the work carried out by Lopez, Moreno, in 2017, an initial investment of 1.186.500 euros was calculated, considering the accumulated inflation from 2018 to November 2023. Regarding the activation of the region's own trades, we proceeded to analyze those related to pottery, ceramics, use of sheep wool and wood crafts, considering it essential that they go hand in hand with ecological and active tourism.

Summary
In the current context of climate change and the increasing demand for energy, the development of sustainable renewable energies has gained considerable significance. One efficient and practical way to harness solar light, which is the most abundant, clean, and safe energy source, is to convert it into electricity through photovoltaic cells. In this field, polymeric organic solar cells have the potential to become an economical and straightforward means of obtaining energy. The main objective of this TFM is to elaborate various computational studies to simulate, optimize, and maximize the performance of an inverted organic/polymeric solar cell of the BHJ type based on fullerenes, specifically with an active layer of PTB7-Th:PC70BM. To perform these computational analyses, the SILVACO/ATLAS TCAD simulation software will be employed, as it is a predictive tool that provides detailed information that is difficult or impossible to measure and it conveniently captures and visualizes theoretical knowledge.

Summary
On the way to a more sustainable and environmentally friendly society, the development of new energy sources plays a fundamental role. To replace fossil energy sources with less polluting ones, it is necessary to provide new and imaginative ideas that offer solutions to problems that consumers can not solve using conventional energy sources. Throughout this work, an economic and environmentally friendly solution to the problem of lack of electrical power existing in the Asprodico building in Ponteareas after being renovated is presented. For this purpose, a photovoltaic system with energy storage through lithium batteries is proposed. The installation will have a power of 30 kW to cover the needs of the center. In this project, the consumption that the building will have after the installation of new devices for heating, cooling, and Domestic Hot Water are explained. The calculations made to size both the photovoltaic system, the storage system, and the wiring and corresponding protections are also shown. Finally, a brief overview of the installation assembly and commissioning is carried out, an important fact being that it is an installation with parallel connection between inverters, which needs to be adjusted with a very specific configuration to function correctly.

Summary
This work focuses on the planning and design of a wind farm in the province of Lugo, addressing fundamental aspects from identifying strategic locations to conducting a comprehensive assessment of environmental and technical feasibility. The project begins with a detailed analysis of regional regulations applicable to wind farm installations, followed by an evaluation of environmental and technical constraints affecting site selection throughout the province. In addition to regulatory considerations, criteria such as the necessary surface area to minimize wind wake effects and the study of local wind resources are incorporated, including the selection of nearby measurement towers. Following the identification of three promising zones, an in-depth analysis is conducted to propose an optimal configuration of wind turbines based on the specific wind resource of each area. Net calculations are performed for different machine configurations, allowing the determination of the most favorable zone among the three selected. In addition to the technical evaluation, the project underscores the importance of an integrated analysis that considers environmental impacts and sustainable development opportunities. The goal is not only to maximize energy efficiency but also to minimize visual and environmental impact, ensuring compatibility with the natural and cultural environment of the province of Lugo.

Summary
The project focuses on evaluating a roadmap for Catalonia's energy transition (PROENCAT 2050) towards a sustainable, decarbonized model by 2050. This transition, guided by 12 fundamental principles, aims to significantly increase renewable energy capacity while foreseeing a sharp reduction in fossil fuel usage. To assess the proposal's viability, the current state of Catalonia's energy matrix has been reviewed, comparing it with that of Spain. Dependency on fossil fuels, energy consumption, electricity production, and associated greenhouse gas emissions have been analyzed. Finally, the main challenges identified include land use issues for new renewable energy installations, the potential to exacerbate territorial and economic inequalities, and the need for inclusive, participatory management to ensure sustainability and social equity. In conclusion, Catalonia's energy transition towards a sustainable, decarbonized model is crucial yet complex, requiring both economic investments and changes in the social and physical structures of the territory. Successful implementation hinges on meticulous planning and an inclusive approach that addresses both inequalities and technical and social challenges.

Summary
An automatic optimization procedure is proposed for a Parallel-Plate Avalanche Counter with Optical Readout, designed for heavy-ion tracking and imaging. Exploiting differentiable programming and automatic differentiation, we model the reconstruction of the position of impining 5.5 MeV alpha particles for different detector configurations and build an optimization cycle that minimizes an objective function. We analyze the performance improvement using this method, exploring the potential of these techniques in detector design.

Summary
The aim of this work is the study of the mesons made up of heavy quarks and antiquarks, known as quarkonium, and its interaction with the medium. Quantum Chromodynamics (QCD) predicts that, at sufficiently high densities and temperatures, hadronic matter goes under a phase transition involving the formation of the quark gluon plasma (QGP). Among the proposed signals for the study of quark gluon plasma, particles formed by quark-antiquark c assume a main role because of the modification of its properties as a function of the density and temperature of the medium. In this work we will analyze quarkonium’s behaviour in the presence of the medium originated in nuclear and hadronic collisions. In particular, we will study proton-proton collisions and we’ll see if similar phenomena as the expected in nuclear collisions can appear in smaller systems as well as what could be its origin

Summary
In this work, a study of direct CP violation in the B0 DK+pi- decays is developed based on the Dalitz plot analysis. This involves carrying out a selection process of B0 meson candidates. This process includes applying cuts on Trigger variables, rectangular cuts on kinematic variables, as well as those related to particle identification. Particle identification variables from the simulation sample are subjected to correction using the PIDCalib package of LHCb. Once the preselection is completed, multivariate Machine Learning methods are trained to refine background reduction in the data sample. Subsequently, a model is proposed for the invariant mass distribution of B0 meson candidates, incorporating contributions from both background and signal. Fitting this model to the complete data sample and sub-samples corresponding to different bins of the Dalitz plot provides the parameters necessary for calculating the total asymmetry and asymmetry in different regions of the phase space, respectively. The data used were collected from proton-proton collisions at LHCb during Run 2, between 2015 and 2018.

Summary
The objective of this work is to become familiar with the helicity formalism and its utilization in perturbative QCD. The helicity formalism provides a convenient way to calculate scattering amplitudes involving massless particles with spins. The project is divided into two parts. The first part of the project includes a thorough explanation of the helicity formalism, encompassing spinor variables for both quarks and gluons. In the second part, a detailed calculation of the amplitudes for dijet processes is carried out within this formalism. The squared amplitudes, after summing over spins and colors of the incoming and outgoing partons, agree with well-known results found in standard QCD textbooks, which are typically given without detailed derivation.

Summary
Radiotherapy is a form of medical treatment that exploits the biological effects of ionizing radiation for therapeutic purposes, commonly used for cancer treatment. Unlike the more well-known external beam radiotherapy, metabolic radiotherapy uses radiopharmaceuticals administered systemically to the patient, designed to preferentially target the tumor. This approach allows for internal irradiation of the patient, focusing the energy deposition on the target organs and minimizing damage to healthy tissues.\\ Despite the therapeutic potential of metabolic radiotherapy, its clinical use is limited by the lack of precision and individualization of the current dosimetric methods. This shortcoming is due to the systemic nature of the treatments, since it requires a precise characterization of the activity distributions in the patient's organs and their temporal evolution in order to estimate the dose to be delivered.\\ Using external radiation detector systems and individualized Monte Carlo simulations, it is possible to extract information about the distribution of activities within the patient, allowing for a more accurate estimation of the dose delivered to each organ of interest. The purpose of this work is to advance in the development of this methodology, delving into the implementation of personalized and realistic simulations, as well as studying the technical characteristics of the external detectors that would be employed for this purpose.

Summary
The Phi meson production is analyzed from the dimuon spectrum in proton-lead collisions at sqrt(s) = 8.16 TeV recorded by the LHCb detector, using both the forward (pPb) and backward configuration (Pbp). The objective is to measure the production of these low mass mesons versus the multiplicity of the collisions. The production increase of the Phi strange particle with multiplicity is an effect related to the formation of the Quark Gluon Plasma (QGP) called strangeness enhancement. The QGP is the state in which matter was a few microseconds after the Big Bang.

Summary
The Energy Transition is based on high technology, which means that without a stable rare earths (REE) market, it will be difficult to follow the path set by the Paris Agreement. The main producer of rare earths is China, accounting for almost 70% of world production. Therefore, if China decides to reduce foreign trade to supply its domestic market, the objectives set may be at risk. This is why Europe is committed to the recycling of electronic waste. Among these wastes are permanent magnets, which are a great source of rare earths, especially Nd. This master's thesis is a subtask of the Harmony project. The project aims to boost the independence and competitiveness of European industry by developing on a pilot scale an innovative, environmentally friendly, and safe closed-loop recycling process for rare earth elements from NdFeB permanent magnets. This subtask starts with a composition of Al2O3 CaO Nd2O3 from scrap metal. For its recovery, a hydrometallurgical process with organic acids has been used to reduce the toxicity of the process. First, a leaching process was carried out with different variables (temperature, solid/liquid ratio, acid concentration, etc.) and the optimum point of the process was obtained using the Minitab program. Once the optimum point was obtained, kinetics and precipitation were carried out

Summary
This Master's Thesis (TFM) aims to conduct a comparative analysis of greenhouse gas (GHG) emissions through life cycle assessment (LCA) for bioenergy generation from pig and cattle waste in Argentina. Specific objectives include creating a detailed inventory using primary and bibliographic data and calculating GHG emissions derived from bioenergy production from biogas generated by these wastes. The study is based on the life cycle assessment (LCA) methodology to evaluate the environmental impacts of biogas production. Various stages of the life cycle were analyzed, from waste collection to bioenergy production. The research reveals that despite the decrease in per capita beef consumption, intensive rearing in feedlots facilitates waste collection, increasing its potential as a raw material for biogas. Emissions were compared before and after economic allocation, showing a significant reduction in emissions from the cattle system due to a low allocation factor applied to the animal finishing phase. The results also highlighted the efficiency of cattle and pig manure in biogas production, requiring less than one head of livestock to produce 1 kWh. Additionally, the economic and social implications of implementing bioenergy systems were explored, emphasizing job creation and environmental cost reduction as key benefits.

Summary
This paper presents the development of a case study, which involves the rehabilitation and expansion project for a single-family home located in the O Barco de Valdeorras area, in the province of Ourense, with the ultimate goal of obtaining Passivhaus certification in the Rehabilitation modality (EnerPhit). The study highlights the importance of energy rehabilitation in meeting the commitments made by the Spanish state towards the EU’s 2030 targets, considering that more than 50% of residential buildings in Spain were built before 1980, of which 84.5% have energy ratings of E, F, or G. Additionally, a case study is analyzed where heritage regulations impose significant limitations on the range of possible actions, making the high-standard Passivhaus certification a major challenge. The project compares a baseline building that complies with the technical code (Scenario 01) with two certification options of the Passivhaus standard under EnerPHit rehabilitation: By energy demand (Scenario 02) and By components (Scenario 03). In Scenario 02, the additional investment in thermal insulation is 2.07%, while in Scenario 03 it is 0.66%. However, the annual energy savings are greater in Scenario 02, at 65.3%, compared to 48.49% in Scenario 03. Considering increases in electricity costs (5%, 7%, and 10% annually), Scenario 02 recovers its investment in 13 years, but offers greater medium-term savings (20 years). On the other hand, Scenario 03 recovers its investment more quickly, in 7 years, although with lower long-term savings compared to Scenario 02.

Summary
The intersection of superconductivity and nanofabrication presents significant potential for advancements in quantum technologies, particularly in the development of highly sensitive photonic detectors. In this work, the design of a superconducting photon sensor with single- and few-photon capabilities is proposed. This device had been previously studied via a primitive thermal model as an assessment of its viability, yielding positive results. This report serves as a continuation of this preliminary study and aims to perfect its calculations and identify the advantages and restrictions of the design. This is done by building a more accurate computational model that solves the heat equation numerically for the proposed sensor geometry and materials. The new simulation pairs the thermal dynamics analysis of the system with calculations of the electrical current distribution, so that Joule heating may be considered as a contribution to the heat equation. Application of this computational model to different cases seem to confirm the viability of the device as a detector capable of discriminating different numbers of simultaneous impinging photons, under certain conditions.

Summary
The present work examines the training of quantum generative adversarial networks or QGANs for a reduced number of cases in the generation of a target distribution. While quantum neural networks have been previously proposed as quantum GANs, improving the training accuracy remains a subject of active research. This study focuses on optimizing the ansatz as a way to improve training in terms of metrics such as relative entropy. Two approaches are proposed: the use of mixers, which are expected to increase the entanglement, and the inclusion of progressive ansatz, analogous to progressive GANs in classical deep learning. To identify the general features of training improvements through ansatz engineering, 1-dimensional distributions are studied. Circuits commonly used in QNNs such as the EfficientSU2 and its variants were used to study their performance as generators. Variations in the depth of the circuits, as well as the increase of the levels of entanglement through control gates have allowed to increase the understanding of the training process. Meanwhile, it has been seen that the use of progressive training on circuits designed with the application of this same methodology in mind increases the quality of the results obtained in QGANs, achieving relative improvements of around 50% in terms of the Kullback Leibler divergence.

Summary
Quantum computing is a rapidly evolving field, with almost every aspect of it open to change or improvement. Among these changes, a very promising one is the evolution from one quantum processing unit (QPU) to several, in a new paradigm called distributed quantum computing (DQC). Some research is already underway in this area to prepare the ground for an eventual architecture with these characteristics. This is the case of InQuIR and NetQASM, two languages for DQC. This paper attempts to compile the first, InQuIR, into the second, NetQASM, in order to create a compilation stack for this paradigm. An example of this compilation is shown, together with a simulation of the compiled code to check its correctness.

This paper attempts to compile the first, InQuIR, into the second, NetQASM, in order to create a compilation stack for this paradigm. An example of this compilation is shown, together with a simulation of the compiled code to check its correctness.

Summary
In this work, we analyze the electrochemical interface in ternary mixtures of ionic liquid (IL), lithium salt, and water using Molecular Dynamics (MD) simulations. ILs, divided into protic and aprotic types based on their hydrogen-bonding abilities, are increasingly used as electrolytes in batteries due to their unique properties. The research focuses on H2O-EAN-LiNO3 and H2O-EMIMBF4-LiBF4 mixtures across various water molar fractions, while maintaining low water concentrations due to its limited electrochemical stability when free. The MD simulations employ the OPLS-AA force field, using implicit walls to study the interface. The structure of layers near the interfaces, the structural and orientational organization of molecules, as well as charge profiles and potential drop in these regions will be studied for both neutral and charged walls. Additionally, the analysis of velocity autocorrelation functions (VACFs) and their Fourier transform, the vibrational density of states (VDOS), will allow us to study lithium molecular cages at the interface, whose evolution will depend on both the addition of water and the presence of an electric field. Characterizing these regions is vital to investigate the applicability of these mixtures as electrolytes in lithium batteries. For neutral walls, the different protic or aprotic nature of the ILs will be the key factor in determining the interface structure, while in the presence of an electric field (charged walls), this will become the crucial element.

Summary
Magnetic Resonance Imaging (MRI) is nowadays a crucial diagnostic tool, which generally uses the response of atoms such as hydrogen, carbon or fluorine to generate three-dimensional images. In this work, a reproducible experimental procedure has been developed for the synthesis of lipid nanoparticles encapsulating perfluorooctyl bromide (PFOB), a compound with a high content of fluorine atoms. The main objectives of the study included the structural and morphological characterization of the nanoparticles by Dynamic Light Scattering (DLS) and Transmission Electron Microscopy (TEM), the confirmation of the presence of 19F in the nanoparticles using nuclear magnetic resonance spectra, and the validation of their visualization by MRI in a preclinical 9. The results demonstrated the successful development of the experimental method, the detailed characterization of the nanoparticles, the detection of 19F in the nuclear magnetic resonance spectra, and the obtaining of magnetic resonance images of the samples with nanoparticles, thus establishing a solid basis for the use of PFOB nanoparticles as contrast agents in magnetic resonance imaging.

Summary
This Master's Thesis aims to generate optical vortices using amplitude diffractive elements to explore their potential application in the direct imaging of exoplanets. The goal is to capture the light from these planets while preventing light from their host star from saturating the detectors. The star light is much brighter than the one from the planet. To achieve this, these diffractive elements are fabricated and their performance extinguishing starlight is evaluated. After a brief overview of the state of the art in exoplanet imaging and the physics behind optical vortices and some of their applications, the experimental work begins with the design of a series of diffractive plates, using diffraction gratings with different periods to generate vortices of different orders. Next, the fabrication of these diffractive elements using lithographic techniques is carried out. The second part consists of the experimental characterization of the fabricated plates. A collimated beam is used to simulate the star or the planet, and a variable aperture telescope incorporating a coronagraph is set up, where the plates are placed to perform a qualitative study and, later, measurements of the extinction obtained . The objective is to analyze how the vortex order and period parameters affect the maximum extinction. A discussion on the effects of the element quality, the influence of some reflections, and the angular distance is included. Finally, the results obtained are compared with another coronagraph, the Lyot coronagraph, showing that implementing amplitude diffractive elements in coronagraphy is useful for the direct imaging of exoplanets.

Summary
In this TFM thermophysical and tribological properties were experimentally studied for five vegetable oils: sunflower, soybean, corn, neem and castor oil. A prhoT apparatus based on a vibrating tube densimeter was used to experimental determine the volumetric behaviour at temperatures from 298.15 K to 373.15 K and from 0.1 MPa to 80 MPa. A rotational viscometer was used to determine the viscosity and the viscosity index. Friction coefficient measurements were performed with a ball-on-three-pins configuration moreover an optical profilometer was utilized to quantify the wear and the roughness of the surfaces. A total of 610 new density, compressibility, expansivity and viscosity data are reported. Castor oil has the highest density and viscosity and the lowest isothermal compressibility and viscosity index. The thermal expansivity of sunflower oils is independent of the temperature at 20 MPa and 10 MPa, respectively. The wear track depth, worn area and surface roughness of the contact lubricated with corn oil are the highest, suggesting more significant wear. The results showed that neem and castor oils have the best anti-friction behaviour, thus the friction coefficient of both oils are respectively, 40 % and 20 % lower than those of sunflower, soybean and corn oils.

In this work, nanoparticles of the metal organic framework (MOF) type containing Cu in their lattice have been obtained through synthesis processes in aqueous medium and room temperature: CuMI and Cu3(HITP)2. MOFs have been characterized based on their catalytic and energy storage capabilities. To this end, a spectrometric study of a rhodamine B reaction catalyzed by MOFs and a study of cyclic voltammetry and charge and discharge curves of MOFs have been carried out. In addition, we complemented the analysis by comparing the results with the data obtained for ZIF-67, a reference MOF due to its catalytic and energy storage applications.

Summary
In this work, we carry out an analysis of two atmospheric variables in five Galician cities in the context of climate change for the coming decades. For this purpose, climate models reproducing precipitation and temperature are used to work with historical and future time series. Due to the presence of biases and limitations in the models, the first part of the work consists of applying correction methods to the chosen models using observation time series given by stations in the study cities. From a statistical analysis, a decision is made on the method that obtains a corrected series that best matches the observed series. Once we have one or several optimal methods, we can analyse the future series. To do this, we obtain probability distribution functions of the corrected future and historical series for all the models used and the study cities. The final analysis focuses on the behaviour of extreme values of temperature and precipitation in relation to global and regional climate change. It is also intended to draw conclusions about the models and methods used and their comparisons, the future behaviour of the climate in Galicia and possible improvements of the work.

In this master thesis we present a generalization of the procedure first developed by Halcrow and Harland to obtain the nucleon-nucleon interaction potentials using the Syrme model. We begin by presenting the generalized Skyrme model and studying the 2-skyrmion system as a pair of classical rigid bodies. We find explicit expressions for the metric and potential energy, which fully characterize the system, and develop the scrips needed to compute them numerically using the symmetrized product approximation. Finally, we describe the quantization of the 2-skyrmion system providing expressions for the nucleon-nucleon potentials as functions of the components of the metric and potential energy. Definitive results employing the procedure and scripts described in this thesis are expected to appear in a publication in the near future.

The CALIFA calorimeter, composed of inorganic CsI(Tl) scintillator detectors, constitutes one of the main detectors of the R3B experiment at the GSI-FAIR facility (Darmstadt, Germany). During a campaign to characterize the calorimeter crystals, they were subjected to protons of different energies incident at the nuclear physics center facility in Julich, Germany. The experimental setup consisted of several crystals of different geometries and a silicon detector that allows determining the direction of incident protons. The aim of this master's thesis is to analyze these data to characterize the passage of protons through the crystals, the distribution of energy among them due to transmission and light losses through coatings, the energy loss in protective materials when protons traverse more than one crystal, as well as the resolution and detection efficiency of CALIFA components. For this purpose, identification of the obtained information will be carried out, detector calibration will be performed, and a study of the correlation between them will be presented.

Summary
The study of nuclear structure is a very active research field. Originally, single-particle nuclear shell models were extremely succesful in describing nuclear phenomena. However, as both experimental techniques and theory advanced, much more phenomenology was discovered, which was incompatible with a pure single-particle model of nuclei. This Master thesis focuses in the study of the quenching of single-particle motion of nucleons inside atomic nuclei. In particular, the focus is in the single-nucleon transfer reaction 15C(p,d)14C, for which an experiment was previously carried out in 2023. The experiment used the Argonne Tandem Linac Accelerator System (ATLAS) for the production of a 15C secondary beam, which was sent into the Active Target Time Projection Chamber (AT-TPC), which was the active target detector used for the experiment. The current status of the analysis of the data from this experiment is shown in this text. So far, a preliminary optical potential for the elastic scattering of the 15C+p system was obtained, and a preliminary cross section for the transfer channel was determined. Some problems appeared during the analysis process, which show that more study about the AT-TPC response may be needed before achieving more conclusive results.

Summary
In this work, we investigate the high-energy behavior of Quantum Chromodynamics (QCD) by studying quark-photon jet production in proton-nucleus (pA) collisions at forward rapidity, focusing on the lowest order in the electromagnetic coupling in perturbation theory. We employ two key frameworks: Transverse Momentum Distributions (TMD) factorization and the Color Glass Condensate (CGC) theory, that describes the nucleus as a collection of classical gluon fields. These two approaches are critical for understanding hadronic behavior under extreme conditions, especially in the small-x regime where gluon saturation becomes significant. We begin by discussing the asymptotic freedom of QCD and introducing light-front quantization, leading to light-front perturbation theory, a key tool for our analysis. The small-x regime of QCD is then explored, with CGC theory modeling the non-linear gluon saturation and TMD factorization providing a detailed description of transverse momentum distributions of partons. Finally, we show that TMD factorization and CGC converge in an overlapping domain corresponding to the correlation limit of quark-photon production in pA collisions at high rapidity. A detailed derivation of the production cross section confirms the consistency between these two approaches, offering insights into high-energy collisions and parton dynamics in the small-x regime.

Summary
This work is part of the discipline of air shower detection through radio-pulses. It tackles the modifications of the frequency spectrum in air, assuming constant density, as the observer moves closer to the shower maximum and the Fraunhofer approximation ceases to be valid. The work seeks to find the distance beyond which this approximation isn't useful, as well as describe and explain, if possible, the behaviour of the emission when distance and angle of the observer change.

Summary
In this work, we describe the initial tests conducted on the candidate detectors for determining the passage of cosmic radiation in the quantum computing structure of CESGA (Qmio). This detection structure will enable the quantification and reporting of cosmic radiation passing through the processor. These events induce massive and correlated transitions in the qubits, leading to state preparation errors. These highly correlated errors cannot be corrected by quantum error correction codes, difficulting the scalability of the system. The detector is composed of two Amcrys UPS-923A plastic scintillators, each 1 meter long, with Hamamatsu R-750 photomultipliers coupled at their ends, in perpendicular position. The study of events that simultaneously impact both bars allows for an accurate characterization of the system’s detection efficiency. This work put stress on the spatial and temporal properties of the detectors, which are necessary to determine the incidence of cosmic rays in the processor with the highest possible precision. These include the signal speed along the bars and the spatial and temporal resolutions. The attenuation properties of the bars are also evaluated by studying variations in signal amplitude as a function of the distance traveled. In addition to studying cosmic radiation events, the detection efficiency of beta radiation is also quantified using a strontium-90 source.
