Summary
For the design of a plant for the production of monoethanolamine from ammonia and ethylene oxide, the production process is divided into three sections: Conditioning: contains an absorption column in which ammonia is absorbed in water, the objective of which is to achieve a given ammonia composition at the reactor inlet. This absorption column will be designed by Irene Vidal. Reaction: this section can be composed of one or two reactors. In both cases, the equipment is isothermal. Everything will depend on the catalyst and the selected separation conditions. The exothermic reactions that occur inside the reactor are those produced by ammonia and ethylene oxide, obtaining ethanolamines (ETAS). They are carried out in liquid phase with second order kinetics. Adrián Ramos will design a single reactor). Separation: the last section is composed of a set of distillation columns, whose function is to separate the monoethanolamine from the different by-products. The distillation column will be designed by Carlos Rodriguez.

Summary
The aim of this project is to design a plant for the production of pentanoic acid from y-valerolactone. The proposed plant will produce 50,000 t/year of pentanoic acid with a purity of 99% and will operate continously for 24 hours, 330 days a year. The process will start with the conditioning of the raw materials, green hydrogen and y-valerolactone, together with a reaction stage. The latter willl aim at obtaning pentaoic acid and 2-methyltetrahydrofuran as a by-product. The reaction stage takes place in a catalytic reactor R-101 by hidrodeoxygenation of y-valerolactone. This equipment will be designed by Manuel Martínez García. The process continues with a first separaction stage where the unreacted hydrogen is recovered. Finally, the rest of the compounds are taken to a separation train consisting of three destillation towers. Of these three columns Noemí Mallón González will carry out with the rigorous desing of the last, T-303, where the pentanoic acid will be separated from the y-valerolactone.

Summary
The new coronavirus (COVID-19), which appeared in the Chinese city of Wuhan in 2019 and rapidly spread worldwide and became a pandemic, caused extensive damage, both human and material. Early detection of cases is therefore essential to prevent the spread of the virus. In this context, machine learning techniques, especially computer vision and convolutional neural networks, are becoming popular for their high accuracy in disease detection and classification. This work aims to analyse medical images through the use of deep learning techniques, specifically convolutional neural networks (CNN). The study focuses on three types of clinical cases: healthy lungs, lungs with pneumonia and lungs with COVID-19. Different network architectures are used, such as VGG16, VGG2 and VGG3, applying various enhancement techniques to optimise the results. The methodology includes the collection and pre-processing of an X-ray image dataset, followed by the implementation and training of CNN models. Techniques used to improve the performance of the networks include data augmentation, dropout, transfer learning and fine tuning. In addition, a web application was created that allows the user to upload an image and receive a classification, indicating whether the image corresponds to a normal lung, COVID-19 or pneumonia. This application facilitates the practical visualisation of the results obtained and their clinical utility. The results obtained show that the binary classification model with VGG16 and transfer learning and fine tuning techniques provides the best results, especially in the context of unbalanced data. The experiments performed demonstrate the effectiveness of the techniques applied to mitigate overfitting and improve model accuracy. The implementation of improvement techniques, such as data augmentation and transfer learning, is crucial to obtain more accurate models.

Summary
Periodontal diseases are a group of chronic conditions that affect the tissues that hold teeth in place. The main way of assessing the state of these oral tissues to diagnose patients and analyse their evolution is by performing periodontograms. The data obtained when performing a periodontogram can be recorded manually or digitally using different tools. However, most of the existing tools for periodontograms have some limitations, such as the need for an Internet connection. This report presents the work carried out for the implementation of a new desktop tool for periodontograms, PERIOSTAGE, which provides a number of significant advantages over existing solutions. It not only allows offline data recording, eliminating the dependence on a network connection, but also provides graphs and visual summaries of the patient's periodontal status. In addition, the application analyses the periodontogram to determine a periodontal diagnosis according to the most widely accepted criteria in the dental community, improving the accuracy of this assessment and facilitating treatment planning accordingly. Finally, all of this is integrated into an intuitive and easy-to-use interface.

Summary
In corporate environments with multiple printing devices, efficient printer management is essential to reduce wait times, minimize unnecessary movements, and ensure users choose the most suitable printer for their needs. The variety of features among printers can make selecting the right device challenging, leading to ineffective management and reduced productivity. This problem intensifies in large organizations where the lack of clear information about the status and location of available printers can result in suboptimal utilization of printing resources. To address this challenge, this Final Degree Project focuses on the development of NoTimePrinting, a web application designed to optimize printer usage in corporate environments. This solution presents an interactive map that displays the distribution of printers, facilitating visual and accessible management of printing resources. NoTimePrinting also includes an advanced recommendation system that suggests the optimal printer based on parameters such as print job characteristics, user location, or the status and features of printers registered in the system.

Summary
Cardiovascular diseases are currently the main cause of death globally. In research, different topics are being addressed both from the Cardiology Service of the Hospital Clínico Universitario de Santiago (SC-CHUS) and from the Centro Singular de Investigación en Tecnologías Inteligentes (CiTIUS) of the Universidade de Santiago de Compostela. In this context, a common goal of collaboration between both entities arose in the search for a method for the automatic segmentation of the regions of interest of the heart that was fast and reliable to be able to process large amount of data efficiently. In this project, a basic model of convolutional neural network based on the U-Net architecture has been implemented, which has evolved with successive improvements until the final proposal, which is a convolutional neural network based on the U-Net architecture that performs a cascade segmentation in two phases. In the first phase, it works with low-resolution images to cut them to the cube of interest (which encloses the heart) and in the second phase in works with the cut images at a higher resolution to segment the heart into 7 substructures: the 4 chambers, the myocardium of the left ventricle and the great vessels. To train the model, since SC-CHUS does not have expert annotated data, images from the Multi-Modality Whole Heart Segmentation (MM-WHS) competition were used. The proposal of this project has also been evaluated with the criteria of the competition, obtaining better results than those of the methods that make up the state of the art but with the advantage of being less computationally complex, which means that it requires less inference time and has the capacity to be used even if powerful computing resources are not available. The final proposal has been validated with images from clinical practice provided by the SC-CHUS, which are very different from those of the MM-WHS. Even so, very satisfactory results have been achieved with correct segmentations in most cases and with a computational complexity that can be assumed in portable computers.

Summary
This work explores the state of the art of Bluetooth pentesting tools, evaluating their ability to identify vulnerabilities in IoT devices using this technology. It has been demonstrated that while no single tool can cover all possible threats, a combination of them allows for complete and effective security audits. The tools studied include Kismet, Ubertooth, Bluehydra, BtleJuice, GATTacker, Wireshark, BlueScanner, BlueDiving, Blooover, BlueSnarfer, BlueSpam, and BluePrinting, each with its specific capabilities and limitations. Additionally, the importance of a structured methodology, such as BSAM, has been highlighted to improve the coherence and depth of the audits. The implementation of these tools in real audits has allowed for the identification of critical vulnerabilities and the provision of recommendations to mitigate associated risks. This work concludes that the combined use of pentesting tools, along with a robust methodology, is essential to ensure the security of Bluetooth devices.

Summary
This project is based on the production of synthetic fuel from pure methanol from carbon dioxide capture in the atmosphere, wishing to process 44204 tonnes of raw material per year. This process was carried out by designing a distillation column which would remove all the water from the first equilibrium reactor; another multi-tubular fixed-bed reactor was designed with a zeolite catalyst, allowing us to obtain the purest possible hydrocarbon product for subsequent addition of additives. The main objective of this project is to study an alternative to conventional petrol in order to obtain a more environmentally sustainable fuel.

Summary
Power line inspection is a field in constant progress due to the importance of the entire electrical infrastructure in today's society. Most articles that address this topic focus on the monitoring of insulators, leaving aside a large number of components that also have relevance in the power grid. This paper explores the capability of versions of the RetinaNet, Single Shot Multibox Detector (SSD), You Only Look Once (YOLO) and Faster R-CNN models for the detection of a wider number of power grid elements. Finally, the performance of ResNet and EfficientNet classification models for the categorization of insulator defects is also studied.

Summary
Depression has become one of the major chronic health problems globally, and its diagnosis often presents challenges. In Spain, it is estimated that 50% of people with depression are not diagnosed. Although society is advancing in understanding this condition, the stigma of visiting a psychiatrist persists, and it continues to be confused with sadness. Simultaneously, in recent years, the use of artificial intelligence techniques has significantly advanced in the field of mental health. For example, natural language processing (NLP) techniques have been employed to analyze sentiments on social media. However, the number of research studies or projects applying these methodologies for the early detection of depression remains limited. Many people who require psychological intervention are not identified due to the aforementioned obstacles or the global shortage of mental health professionals, among other factors. Therefore, it is important to have a mass screening approach that allows for the detection of depression in its early stages and facilitates the intervention of mental health professionals. The solution proposed in this project is a prototype virtual assistant designed to manage the Geriatric Depression Scale (GDS-VE). This virtual assistant interacts with the user through a fluid conversation, analyzes their responses based on the questionnaire options, and determines the presence or absence of depressive symptoms. The capability of Dialogflow, by Google Cloud, to carry out this task has been experimentally tested. Additionally, the efficacy of pre-trained natural language inference (NLI) models in analyzing and understanding the context of responses and user conversation has been evaluated. The observations and results obtained place these tools in a favorable position for their purpose: to serve as support in facilitating a quick diagnosis of this type of illness. Under no circumstances are they proposed as a substitute for mental health professionals.

Summary
The world of home automation has gone through a major growth phase in recent years and this has led to the emergence of many different manufacturers and systems, and even different communication protocols. This is very good in terms of competition and variety of options, but it can be a big problem to integrate several different systems in the same infrastructure. In this work we develop a simple and scalable architecture that allows us to integrate the information from these systems into a single system centered on an MQTT broker for real-time communication, a database to persist the information that flows through the system, an API to consume that information, a web portal to make information (both API and broker) available to users and a simulator that allows us to create an environment to test this architecture without the need for investment in hardware. And after finishing this work, we concluded that this integration is possible without the need to create interdependencies between the original systems. We achieved this thanks to the fact that the database is isolated behind the API and the latter does not need to interact with the MQTT broker if we use an adapter. In addition, MQTT is an open and lightweight protocol that can be implemented in any other system, or failing that, create new adapters that convert messages from those systems into MQTT messages.

Summary
Mathematical modeling is essential for the understanding and handling of biological dynamic systems. Optimal control problems, which usually include algebraic differential equations as constrains, need to be used. For solving these kinds of problems, of infinite dimension, there are several different types of strategies. In this work, we will delve into direct methods, which perform a discretization of the optimal control problem, transforming it into a finite dimension nonlinear programming problem. In biology, most existing problems involve estimating system parameters from a series of experimental observations. For such a biological problem, a numerical study will be proposed for its solution, varying its configuration, and the results obtained will be commented in depth.

Summary
The rise of artificial intelligence in social robotics and the proliferation of TTS (Text To Speech) systems mean that there can be an integration of both fields, as can be seen in the Furhat robot. This technology is limited to a few languages, recently it was successfully managed to integrate the Proxecto Nos’s TTS into this robot, which allowed Galician speech. However, lip syncing was not adjusted to the Galician language, resulting in an incomplete user experience. This work proposes an alternative lip synchronization for the social robot Furhat during its Galician speech. To achieve this, forced alignment will be used, through the Montreal Forced Aligner (MFA) tool. To align with MFA, we have to create a pronunciation dictionary and train acoustic models with this tool, as none of these resources are currently available for the Galician language.

Summary
The re-identification of people is one of the big problems to be addressed in the field of computer vision. Variations in appearance and occlusions are some of the reasons that make this a complex task. Current models are not yet fully refined, so exploring various alternatives may be beneficial. This work is focused on studying several efficient methods for the initialization of an already existing model, without a prior extraction phase, and mechanisms for detecting duplicate identities. The purpose of this work is to study different alternatives and try to improve an already created person re-identification model, which can achieve comparable or superior performance to current methods, providing a solid basis for future research.

Summary
The aim of this proyect is to desing a plant for the production of pentanoic acid from y-valerolactone. The proposed plant will produce 50,000t/year of pentanoic acid with a purity of 99% and will operate continously for 24 hours, 330 days a year. The process will start with the conditioning of the raw materials, green hydrogen and y-valerolactone, together with a reaction stage. The latter will aim at obtaining pentanoic acid and 2-methyltetrahydrofuran as a by-product. The reaction stage will take place in a catalytic reactor R-101 by hydroxigenation of y-valerolactone. This equipment will be designed by Manuel Martínez García. The process continues with a first separation stage where the unreacted hydrogen is recovered. Finally, the rest of the compounds are taken to a separation train consisting of three distillation towers. Of these three columns, Noemí Mallón González will carry out the rigorous design of the last, T-303, where the pentanoic acid is separated from the y-valerolactone.

Summary
Tuna fishing boats use satellite buoys with acoustic probes and GPS to locate tuna schools. These buoys are deployed in the ocean by tuna vessels and support ships. In their usual operation, tuna boats receive acoustic information from the buoys onboard via satellite, which they must interpret to determine the presence of tuna. This allows for fine-tuning the search for tuna schools, avoiding unnecessary travel and consequently reducing fuel consumption. The placement and collection locations of these buoys are key to optimizing this operation. Marine Instruments is a leading company in the manufacturing of buoys for tuna fishing. In the context of this company, and due to the importance of these maneuvers, the objective of this project is the development, implementation, and deployment of an algorithm that, using the GPS positions of the boats and buoys, can automatically locate the places where these actions occur. The first part of the project involves preprocessing the GPS position information transmitted by the acoustic buoys and the boats themselves to primarily filter and complement the information that may be useful for the algorithms to be developed. The next stage involves the development of algorithms to detect the target maneuvers. Utilizing knowledge about the typical operation of tuna boats and the maneuvers they perform, the necessary conditions or rules will be obtained to apply to the information from the previous stage and detect when and where the maneuvers occur. Finally, the output information from our algorithm will need to be stored in a database. The objective is to maintain a record of all detected activity, both present and past, being able to use visualization tools to monitor the information and conduct studies on fishing activity. Managing the flow of information, from the moment it is generated by the algorithm, to its database loading and subsequent visualization, will also be a task covered within this project.
Tuna fishing boats use satellite buoys with acoustic probes and GPS to locate tuna schools. These buoys are deployed in the ocean by tuna vessels and support ships. In their usual operation, tuna boats receive acoustic information from the buoys onboard via satellite, which they must interpret to determine the presence of tuna. This allows for fine-tuning the search for tuna schools, avoiding unnecessary travel and consequently reducing fuel consumption. The placement and collection locations of these buoys are key to optimizing this operation. Marine Instruments is a leading company in the manufacturing of buoys for tuna fishing.

Summary
Semantic segmentation of multispectral remote sensing images has seen a significant increase in the use of deep learning algorithms in the last decade, due to the high accuracy these methods can achieve. Multispectral images are those captured through multiple bands of the electromagnetic spectrum, beyond the visible bands of red, green, and blue, allowing detailed information about the properties and characteristics of observed objects to be captured. This work focuses on adapting deep neural network models, originally designed for RGB images, to the domain of multispectral images using the PyTorch environment. The main objective is to develop and evaluate efficient and robust models for semantic segmentation, validating their performance with multispectral image datasets. One of the main contributions is the experimental demonstration that deep learning models designed for the semantic segmentation of RGB images can be effectively adapted to multispectral images, utilizing all the spectral and spatial information available in this type of images and achieving high-quality results. This validates the initial hypothesis that these algorithms can be successfully applied in the context of multispectral images, surpassing state-of-the-art models in terms of precision and effectiveness. In the development of this work, typical architectures of deep neural networks are studied and different models are tested to determine which offers better performance in the semantic segmentation of multispectral images. It is identified that, for the dataset used, after approximately 60 training epochs, the increases in precision and mean IoU become minimal, indicating a saturation point. This finding suggests that training models beyond this point does not provide significant improvements in performance but does considerably increase computation time. Additionally, signs of overfitting are observed in some models that continue training beyond this point, which does not improve performance and, in some cases, even harms it. Another important contribution is the verification that deeper architectures do not necessarily offer the best results. Lighter models, such as the ResNet18dilated + C1_deepsup, achieve high precision and good performance with less training time compared to more complex and deep models like the ResNet101dilated + PPM_deepsup. The final tests, conducted with the model that presented the best results in the preliminary tests (ResNet18dilated + C1_deepsup), reveal notable variability in the model's performance among different test images, suggesting that the size of the training dataset might be insufficient to capture all the necessary variability for consistent and generalized performance. This opens the possibility of future improvements, such as increasing the size and diversity of the training dataset to improve the robustness and consistency of the models, optimizing hyperparameters to discover more efficient and effective configurations for the semantic segmentation of multispectral images.

Summary
For the design of a monoethanolamine production plant from ammonia and ethylene oxide, the production process is divided into three sections: -Conditioning: the main equipment is an absorption column in which ammonia is absorbed in water to achieve a certain ammonia composition at the reactor inlet. This equipment will be designed by Irene Vidal. -Reaction: it is mainly composed of two istodermal reactors in which the second-order reaction occurs in the liquid phase between the aqueous solution of ammonia in water and ethylene oxide. This is highly exothermic. It is obtained as a monoethanolamine product and diethanolamine and triethanolamine as a by-product. One of these reactors will be designed by Adrián Ramos. -Separation: to separate the desired product (MEA) it will be necessary to use a distillation column, which will be designed by Carlos Rodríguez.

Initially, we present the theoretical foundation of these reformulations, which were originally developed for binary polynomial optimization problems. Then we extend these results to the broader context of polynomial optimization problems, including non-binary variables (integer and continuous). Finally, we evaluate the numeric results obtained after adapting and implementing these reformulations in a solver.

Summary
In this work we develop an unsupervised time series encoder with continual learning, for its integration with a classification model. Specifically, we adapt an existing time series encoder to be trained with continual learning, allowing the generated encodings to be used as input for the classification model. In addition, in order to evaluate the quality of the encodings, we design a metrics and visualization methods. The experiments show that the performance when using the encoder with continual learning is comparable to the performance obtained when using offline learning, the former situation being more difficult for the model. The integration experiments show that when using the encodings as input for the classifier with continual learning, the performance obtained is satisfactory.

Summary
In this work, various techniques from statistics and machine learning are studied with the objective of developing a model for detecting imbalances in blood potassium concentration using electrocardiographic records. Additionally, it also aims to provide explainability to the results through the identification of the most relevant electrocardiographic features for obtaining the solution. After a cleaning process on the original dataset, we have 2483 electrocardiograms (ECGs) associated with patients with normal, low (hypokalemia), and high (hyperkalemia) potassium concentrations. A feature selection process is carried out on these to obtain a reduced set of variables that allow the correct detection of imbalances in the ECGs and the subsequent explanation of the results. These variables were used to train different models that approached the problem from both a classification perspective (logistic regression, regression trees, Random Forest Classifier, and XGBoost) and a regression perspective (linear regression, decision trees, Random Forest, and XGBoost). Generally, the best results were obtained using the Random Forest model. In the classification of hypokalemia and hyperkalemia, specificities of 95.66% and 86.26%, sensitivities of 13.76% and 48.26%, and AUCs (area under the curve) of 0.73 and 0.76 were achieved. For regression, the R2 obtained was 0.17 and an RMSE (root mean square error) of 0.73. Therefore, none of the models allow the identification of ionic imbalances with a quality comparable to that obtained in previous works, although an advance was made in terms of the explainability of the results.

Summary
The objective of this work is to develop and validate a model for predicting paroxysmal atrial fibrillation (AF) in healthy individuals using machine learning techniques. Unlike other approaches that focus on detecting AF in already sick individuals, this study aims to anticipate the onset of the disease in still healthy individuals. To this end, a dataset of 58,582 electrocardiograms (ECGs) from 11,636 patients was used, which includes an identifier and a total of 493 electrocardiographic features. Some patients remain healthy across all ECGs, while others develop persistent or paroxysmal atrial fibrillation at some point. An important factor in this problem is the irregularity in the timing of ECG samples, as they are performed on patients in an unplanned manner, resulting in data that are not evenly spaced in time. This complicates the resolution of the problem since traditional time series analysis methods cannot adequately handle these irregularities. Therefore, a Latent-ODE (Latent Ordinary Differential Equations) model was chosen, which is particularly suitable for handling these temporal irregularities. Latent-ODEs allow modeling continuous dynamics in a latent space using ordinary differential equations in combination with recurrent neural networks (RNNs). In this latent space, it is possible to capture the underlying temporal evolution of the ECG features, thus providing a more robust and accurate representation of the temporal data. In this way, a Latent-ODE model was developed, along with feature selection and hyperparameter optimization techniques, which allowed us to achieve a best result of an AUC of 0.8812 and an F1-score of 0.7038.

Summary
The objective of this TFG is the design of a plant for the production of isoprene from formaldehyde and 2-methylpropene, also known as isobutylene. The process is carried out in two reaction stages in a production plant with a capacity of 20,000 tons per year, operating 24 hours per day for 330 days per year, reserving the remaining days for cleaning and maintenance. The project includes a summary of the main characteristics and properties of the raw materials and product and a study of the market for them. It also indicates the location of the chemical plant to carry out the process. The alternative selected consists of two reactive phases: in the first, the intermediate product, 4,4-dimethyl-1,3-dioxane, is formed, and in the second, the product of interest, isoprene. The final product is 99% pure isoprene. In addition, an analysis of the technical and economic feasibility is carried out to verify that the necessary technology exists to carry out the project as well as its profitability. The calculation of the material and energy balances of the process and the design of the different units and equipment is carried out, focusing on the design of the first reaction section in which two stirred tank reactors configured in series are located. In reactors R-101-1 and R-101-2 the reaction of 37% formaldehyde with isobutylene in the presence of phosphoric acid takes place to give the reaction intermediate 4,4-dimethyl-1,3-dioxane. An analysis of the control and safety system is carried out, as well as an environmental impact study, and site plans, process diagram, R-101 reactor and control plan are drawn up.

Summary
The objective of this project is to develop a plant for the production of hydrazine hydrate with a mass concentration of 64 percent from ammonia and sodium hypochlorite, both in solution, using the Raschig method. The design is approached with the purpose of producing 12000T/year of product operating continuously, 330 days a year, 24 hours a day. The rigorous design of the most relevant equipment of the process is described, being the hydrazine reactor and the distillation column to obtain the product. It has been decided to address the design of a hydrazine hydrate production plant because of its current research in the energy field for its use as chemical storage of hydrogen in fuel cells due to its high hydrogen content, ease of transport and storage, in addition to the fact that the only by-product of its decomposition would be nitrogen. This is a study of current importance, since it offers an alternative to fossil fuels. On the other hand, hydrazine hydrate is currently used in various industrial fields; due to its ability to eliminate oxygen from water, it is used in high-pressure steam generators and industrial boilers, but it also has other uses, such as foaming agent for plastic foams, polymerization initiators, pesticides, pharmaceutical products, photographic chemical products or dyes. Derivatives of this component also have a great place in today's industry, such as, for example, hydrazine anhydrous, which is synthesized by the Olin Raschig method and is notable for its use as a rocket propellant. The facility is located in the north of Spain, more specifically in the industrial park of Lloreda, belonging to the Asturian city of Gijón, with the aim of facilitating the commercialization of hydrazine hydrate by sea to northern Europe and other commercial areas of interest. This document represents the Final Degree Project by means of which the students Mara Meitín Fraga and Xeila Liñayo Vicente opt for the university degree in Chemical Engineering awarded by the Escola Técnica Superior de Enxeñaría of the Universidade de Santiago de Compostela.

Summary
Nowadays, society uses their technological devices for increasingly complex tasks that requires a huge use of the CPU, so the designers of the processor models and architectures need to adapt to these changes. Based on this need, it exists an architecture called big.LITTLE and designed by ARM that has cores with different efficiencies that allows the execution of the most computationally expensive tasks in the most efficient cores and the simple tasks in the cores with a lower performance and a lower energy consume. This work is developed in this context, creating an API that allows users to control the different cores of the processor. It also gives the users the ability to assign a core to a specific task. First, the API allows users to perform a speed test on a specific core and later, the assignment of one or more cores to a task.

Summary
This final degree project is part of a research project in collaboration with the Department of Cardiology of the “Hospital Clínico Universitario de Santiago de Compostela” on the prediction of survival in patients involved in cardiac rehabilitation programs. This topic is of utmost interest since heart disease is responsible for a large number of deaths each year and there is a lack of information about the aetiology of many of these diseases. The medical team designed and proposed a three-year rehabilitation program to several patients with a history of cardiovascular disease. The medical follow-up resulted in a database of more than 3,000 patients and more than 300 variables. However, as usual in a medical context, mainly due to the lack of automation and standardisation of the data collection processes, the dataset was incomplete, unbalanced and with errors. We proposed a detailed framework to carry out a rigorous pre-processing of the data to obtain a complete and error-free database. This included the investigation of the meaning of variables (their typology, medical significance and fundamental dependency relationships), missing data management (including data imputation), automatic error and outlier detection and variable engineering (calculation of new variables from other variables). After this process we obtained a complete and error-free database of 445 patients and 83 variables. We then proposed the use of different statistical techniques to carry out a correlation study between the variables, and finally we addressed the prediction of adverse events such as hospital readmission or myocardial infarction. The correlation study showed significant relationships between different variables, including obvious ones (such as weight and abdominal circumference), others that would be expected from a cardiovascular point of view (such as severity of myocardial infarction and worse heart function), others that were unexpected (such as younger age with depression and worse diet), and others that require medical knowledge to interpret (such as atrial fibrillation and its usual medication). We found that it was not possible to attempt to predict any of the major cardiovascular events included in the dataset with the minimum of confidence, since after the necessary data preparation process, there were insufficient representative samples of these cases. This report presents a set of techniques for conducting a population-based, variable correlation, and event prediction study that can be used as a guide in similar medical studies.

Summary
For the design of a monoethanolamine production plant from ammonia and ethylene oxide, the production process is divided into three sections: -Conditioning: This section contains an absorption column where ammonia is absorbed in water, with the goal of achieving a specific ammonia composition at the reactor inlet. This absorption column will be designed by Irene Vidal. -Reaction: This section can consist of one or two reactors. In both cases, the equipment is of the isothermal type. Everything will depend on the catalyst and the selected separation conditions. The exothermic reactions that occur inside the reactor are produced by ammonia and ethylene oxide, yielding ethanolamines (ETAS). These reactions take place in the liquid phase with second-order kinetics. Adrián Ramos will design a single reactor. -Separation: The final section consists of a set of distillation columns, whose function is to separate monoethanolamine from the various by-products. The distillation column will be designed by Carlos Rodríguez.

Summary
This final degree project delves into predictive process monitoring, specifically, the prediction of remaining time. This final degree project proposes a model based on the structure of transformers and applies various modifications to it to enhance its learning capacity of the temporal dependencies between different events, using self-attention and cross-attention mechanisms together. In addition, experiments are carried out with the representation of time to observe which measure is more useful and facilitates learning for the model. All of this is tested with various state-of-the-art models that use techniques such as Long Short-Term Memory (LSTM). After analyzing the results, it is concluded that transformers offer a greater learning capacity of these dependencies than other models such as recurrent neural networks (RNN), generating better models. In addition, the combined use of self-attention with cross-attention, and a temporal representation that indicates the duration of the events obtains the best results for most event logs. This work not only provides a new approach to time prediction in business processes, but also establishes a solid foundation for future research and development in this field.
This final degree project delves into predictive process monitoring, specifically, the prediction of remaining time. This final degree project proposes a model based on the structure of transformers and applies various modifications to it to enhance its learning capacity of the temporal dependencies between different events, using self-attention and cross-attention mechanisms together. In addition, experiments are carried out with the representation of time to observe which measure is more useful and facilitates learning for the model. All of this is tested with various state-of-the-art models that use techniques such as Long Short-Term Memory (LSTM). After analyzing the results, it is concluded that transformers offer a greater learning capacity of these dependencies than other models such as recurrent neural networks (RNN), generating better models. In addition, the combined use of self-attention with cross-attention, and a temporal representation that indicates the duration of the events obtains the best results for most event logs. This work not only provides a new approach to time prediction in business processes, but also establishes a solid foundation for future research and development in this field.

Summary
Kronecker's Jugendtraum is related to the problem of finding all abelian extensions of a quadratic imaginary field, therefore generalising the Kronecker-Weber theorem. To study this issue, the main tool is a certain class of elliptic curves, with a specially rich arithmetic structure, called complex multiplication. In this work we will explore the connection between these two topics. We will start by introducing, on one side, the elliptic curves, defining over them a group structure, focusing on finite order points; and on the other, extensions of Q, emphasising those with an abelian Galois group, as well as those generated by roots of unity or elliptic curve points. Afterwards, we will present the concept of complex multiplication and, finally, with the help from group representations, all the previous theory will be used to study a particular case of Kronecker's Jugendtraum, looking at the abelian extensions of Q(i).

Summary
Homomorphic cryptography allows operations to be performed on encrypted data without having to decrypt it. This feature is very attractive because, in particular, it prevents third parties to whom calculations with that data are delegated from accessing it, opening up a wide range of applications. The problem of building a completely homomorphic cryptosystem, which allows arbitrary calculations with encrypted data, was considered the holy grail of cryptography for 30 years. During that time, countless attempts have been made to solve it, obtaining only partial solutions. In 2009, the work of Craig Gentry represented a revolution by introducing the bootstrapping technique, through which some cryptosystems could be made completely homomorphic. From this moment on, different families of cryptosystems with this property have emerged, all of them making use of Gentry's invention. The aim of this paper is to carry out a small comparative study between some of the most widely used completely homomorphic cryptosystems today, specifically BGV, BFV and TFHE, comparing the algorithms that compose them and measuring the execution times. Previously, homomorphic cryptography will be introduced theoretically, defining bootstrapping and making certain considerations regarding the security of these cryptosystems. In addition, a brief historical context and a brief review of the state of the art will be given, presenting the main families of completely homomorphic cryptosystems.

Summary
Demonstration level facility of production of acrylic acid from glycerol as a first approach to the industrial scale development, as the maximum level of maturity achieved was the pilot plant scale. The traditional process for the obtention of acrylic acid is basen on the propylene oxidation, obtained directly from the combustion of fossil fuels. Due to the needs of the industry to support the energetic transition, it is necessary to search for alternatives which lessen the dependence on these type of non-renewable resources. Because of this, this work is based on the selective conversion of glycerol, a coproduct generated in the manufacture of biodiesel, which is obtained from vegetal oils and animal fats. Glycerol will react to produce acrolein in a first reactor, which will be converted into acrylic acid in a second step. This product will be purified by the usage of a flash drum, an absorption column, liquid-liquid extraction and a sequence of distillation columns. In terms of design, the student Daniel Fins Simón developes an hetereogeneous catalytic reactor in gas phase, while the student Pablo Carrera developes a liquid-liquid extraction unit.

Summary
Food waste in Spanish households exceeds 1200 million kg or liters, according to 2022 data (Ministry of Agriculture). Of this, more than 70% refers to unused food, as purchased, due to expiration or spoilage. This indicates a widespread excess in purchasing products at the supermarket and a lack of control over these in the refrigerator or pantry. As a contribution to reducing the impact of this problem, this thesis develops FreshStock, an Android mobile application that helps individuals and households to know and manage their food inventory and expiration dates, assisting in making more conscious consumption decisions. To achieve this, it will focus on greater usability and simplicity, providing useful features such as generating complete shopping lists with a button, organizing products by labels, and a barcode scanner with automatic Internet search for product information.

Summary
The industry drives the economic growth of a country, so its evolution is crucial. Recent innovations are based on the integration of new technologies that improve results and increase productivity. In all of this, collaborative arms or cobots are having a great impact due to their flexibility when working with human operators and their great adaptability to various tasks. For all this, and with the purpose of investigating the operation of new technologies, a system has been designed that integrates a Franka Panda collaborative arm, a GelSight Mini touch sensor, and Aruco markers recognized through an Orbbec Astra camera. The entire integration process is accompanied by challenges and difficulties such as the calibration of the Gelsight Mini or the transformation of coordinates between different reference systems. All designed and developed with the purpose of being able to perceive and manipulate objects of different sizes and materials through a robotic arm, which could later be incorporated into a production line or industrial environments. Furthermore, once the results are obtained, possible extensions and improvements are proposed that would complement the system.

2-Methoxy-2-methylheptane (MMH) is used in various fields, primarily as a gasoline additive or pharmaceutical intermediate. The plant's capacity is 30,000 tons per year since both traditional applications and new chemical-grade alternatives are not high-tonnage applications. MMH is produced from methanol and 2-methyl-1-heptene. As a sustainable alternative, it is proposed to use green methanol from a nearby plant. Pablo Rodríguez-Villamil is responsible for the design of a packed distillation column (T-203). Raúl Veiga Moo is in charge of the design of a catalytic heterogeneous fixed-bed reactor (R-101). Finally, Hugo Vidal Cabanelas is responsible for the design of a plate distillation column (T-202).

Summary
In the field of artificial intelligence research focused on object detection, the pursuit of improvements in the process of analyzing and evaluating datasets and the respective results of detection models is a crucial part of optimizing the entire process both in terms of time and associated resource costs. These evaluations and analyses must be carried out accurately and avoiding, as much as possible, any type of bias. For this, researchers need a wide variety of tools, and coordinating all of them can be complicated and confusing. Moreover, to perform all these training and analysis of detection models, it is necessary to use distributed clusters due to the high computational load their execution entails, causing each researcher to constantly monitor these clusters to stay up to date not only with the status of their own tasks but also with the general status of the job queue. In this work, a platform will be developed that will unify all the necessary tools to maximize the optimization of the research process both in the management and querying of the status of tasks and the job queue in these distributed clusters, as well as in the evaluation and analysis of image datasets in COCO format and the results and detections of detection models. This platform aims to provide a comprehensive and efficient solution, facilitating the researchers' work and improving the accuracy and coordination of their tasks.

Summary
This project consists of the analysis, design and implementation of a software solution that will help a customer to begin the migration of their infrastructure and corresponding configuration to IaC (Infrastructure as Code) paradigm. In the long term it also aims to encourage DevOps philosophy. Its adoption will involve both sysadmins and developers, bringing great benefits to the whole team by reducing the time required to configure and document the infrastructure's current state. Switching to this paradigm also results in a higher quality work and improves response times in multiple scenarios. Attempts to compromise the platform, security audits, deployment and hardening of new servers or publishing new application versions are just a few examples that will be approached more effectively and using less effort. Taking into consideration customer's constraints and existing infrastructure's characteristics, the best alternative will be chosen, the needed modules will be implemented to enable integration with current infrastructure and testing scenarios will be defined in order to validate that the solution works as expected.

Summary
The presence of different pollutants in the atmosphere is the cause not only of climate change, but also of many health problems for people. Nowadays, we have multiple satellites that allow us to monitor the levels of these parameters remotely. However, analyzing a multitude of files and data, for various parameters and days, can be a tedious task. That is why this thesis is proposed, which aims to design a system to monitor the variability and trend of different parameters obtained through satellite data. By downloading this data and its transformation and aggregation, we will be able to significantly reduce the amount of files that will be necessary to analyze, which eases the monitoring of pollution by end users. The development of this system will be done in such a way that it can be easily accessed, and also taking into account the interoperability of the system.

Summary
Human beings spend most of their time, especially today, inside a building, whether to live in it, for work reasons, for leisure... In short, human society focuses on the building throughout its life. Therefore, monitoring the aspects that may be of greatest importance is vital to improve quality of life and/or enjoyment. This fact makes building monitoring, within its different categories, a very useful way of providing information that is complex to obtain and process in another way. This information can significantly help improve the potential of the services that the building offers to its users. Among the various information that can be obtained through building monitoring, the most common is the monitoring of environmental conditions, since they help establish a suitable environment so that both people and other living beings, if applicable, can enjoy high environmental quality. . Furthermore, environmental comfort in a given space is one of the most important aspects when it comes to establishing a suitable place both to live and to visit at the right time. For these reasons, in this report it has been decided to implement a system that allows monitoring the environmental conditions of a building, so that information can be obtained in real time on different environmental factors such as temperature and humidity. Likewise, more measures will be incorporated that can be useful in the day-to-day life of a building, such as presence detection and door opening detection. All this information will be obtained through different types of sensors, which will send the measurements to an IoT node through the Zigbee protocol. Inside the node, all the logic necessary to interpret the measurements will be carried out, in addition to including a graphical interface for greater ease in configuring and monitoring the sensors. Finally, the information will be sent to a platform, where the end user will be able to see both the configured sensors and their respective measurements.

Summary
In the scientific field of remote sensing, multispectral and hyperspectral images capture detailed information in different bands of the electromagnetic spectrum, allowing high-precision analysis of the Earth's surface. This ability to capture multiple wavelengths is ideal for observing and studying the Earth's surface through satellites, drones, or airplanes. In recent years, advances in machine learning have significantly enhanced research in anomaly detection in these images, successfully identifying distinct elements within a specific environment. Recently, the technique known as Isolation Forest has demonstrated superior performance for anomaly detection compared to traditional distance-based methods. Moreover, its approach, based on the construction of isolation trees, allows for more precise anomaly detection, making it a powerful tool in the field of anomaly detection and pushing the state-of-the-art forward. The use of deep learning techniques in anomaly detection offers several advantages compared to traditional algorithms based on pixel distance calculations. Among these advantages is greater adaptability, as neural networks can be retrained with new data to adjust to changes in the environment or the characteristics of anomalies. Additionally, deep learning methods are less sensitive to noise and small variations in data, allowing for more robust performance in complex data scenarios, such as in MSI (Multispectral Images). Among the available algorithms of this type in the literature, Deep SAD offers a deep learning-based approach for anomaly detection that has demonstrated good performance on RGB image datasets. In this work, the Isolation Forest and Deep SAD algorithms have been adapted for use in multispectral images. Additionally, for both algorithms, a hyperparameter exploration was conducted to obtain a parametrization that fits the datasets used, belonging to the hydrographic basins of the Oitavén River. The results obtained by Isolation Forest and Deep SAD on these datasets have been compared with those obtained by the RX method, a consolidated method in the state-of-the-art for anomaly detection in this type of images. The results of the conducted experimentation showed that both proposed methods, Isolation Forest and Deep SAD, achieved good results in anomaly detection in MSI (Multispectral Images). Isolation Forest proved to be particularly effective, detecting a high percentage of the total existing anomalies in the images and significantly surpassing the detection percentages achieved by the distance-based RX algorithm. On the other hand, Deep SAD also managed to improve the number of detected anomalous pixels compared to the RX method, also showing a high capacity to distinguish between classes, achieving a good balance between the number of true positives and false positives.

Summary
Hypertrophic cardiomyopathy is a relatively common genetic disease with a very heterogeneous expression. Although most patients can lead a normal or nearly normal life, a small number of patients are at very high risk of ventricular arrhythmia and sudden death. Some of the reference tests for evaluating the risk of sudden death in these patients are cardiac magnetic resonance or echocardiography. This work raises the possibility of identifying new risk predictors from the electrocardiographic test, whose low cost and wide availability in the service portfolio of public health systems would ensure greater accessibility for the general population. To do this, machine learning techniques will be put into play for the development of a prediction model, as well as variable selection techniques for better interpretability of the results. A database compiled by the Cardiology Service of the Hospital Princesa de Madrid and annotated by hand by expert cardiologists will be used.

Summary
In the current technological era, the demands for processing and transmitting multimedia content are increasing. The vast amount of existing data necessitates efficient systems for information extraction, digitization, storage, and ultimately retrieval. The latter point is crucial as new technologies increasingly demand speed and effectiveness in utilizing all this information. This project aims to emphasize the idea of retrieving images from databases, specifically from storage systems where all this information is kept. Specifically, the development of a tool is proposed that allows retrieving a similarity ranking between images based on their descriptors. These descriptors are sets of numerical values that reflect characteristics of an image such as color or texture. Furthermore, the functionality is proposed to compute these descriptors locally, i.e., on a specific part of the image. This approach gives users more options when retrieving information. This comparison will be carried out between images in a database and a query image chosen by the user. Thus, the tool also integrates all corresponding database management actions, such as adding or deleting a database, or adding or removing an image within a database. Throughout this project, the knowledge acquired up to this point, combined with new knowledge gained during its development, will be applied to carry out valuable work in the field of computer engineering. This could potentially provide an opportunity to contribute value to the current technological world.

Summary
Currently, artificial intelligence is making it possible to solve problems and automate processes that, until now, required human labor. In this work, the problem of stock detection in warehouses will be addressed from the field of artificial intelligence and automation. Manual or semi-automatic methods are the most used for inventory control, but in this work a system based on image processing will be developed that allows situations of stock breakage or replacement to be detected in an automated manner, providing a more efficient and precise solution. To achieve this, this problem will be divided into different smaller challenges that will be addressed sequentially, finally building a complete system that will be able to detect movement, crop areas of interest in the images using ArUco markers, transmit the data efficiently using Kafka and classify the images using the CLIP model to monitor these inventory changes. Finally, the performance of this system will be evaluated to determine its viability as a real alternative to traditional inventory management methods used in warehouses.

Summary
Stress has become an increasingly prevalent illness, and along with the growing concern of contemporary society about mental health issues, it has become of great interest both to detect it and to study its causes. In this context, the following work has focused on the detection of stress through machine learning and deep learning techniques applied to physiological signals, specifically electrodermal activity (EDA) signals. To approach this research, an analysis of the current state of the art was conducted, replicating previous studies to understand and then improve them. Two public datasets were used: WESAD and AMIGOS, which provide records of physiological signals in various contexts and through different experiments. The methodology included data preprocessing, extraction of relevant features, and implementation of various classification models, both machine learning (SVM, Random Forest) and deep learning (neural networks). An advanced model combining Convolutional Neural Networks (CNN) with Long Short-Term Memory (LSTM) was developed, exploring the impact of modifying their configuration parameters, resulting in high accuracy. Additionally, validation techniques were enhanced by combining cross-validation and the leave-one-subject-out technique. The experimental results demonstrated that deep learning models significantly outperform machine learning models in terms of accuracy, achieving up to 98% precision with LSTMs. The generalization capability of the trained models was also evaluated using both datasets, observing superior consistency in deep learning models compared to notable disparities in machine learning models. These findings underscore the effectiveness of deep learning techniques in capturing complex relationships in physiological signals and improving stress detection.

Summary
LiDAR technology allows us to obtain three-dimensional scans of a surface or object at a very high resolution, but its processing, especially the calculation of the neighbors of a point, is very expensive both in terms of time and memory the more points a cloud has. One way to improve the performance of point cloud processing algorithms is to parallelize them, thus distributing the workload between different processing units. The objective of this work is to implement a solution to this problem, developing a point cloud partitioning algorithm and subsequently processing the clouds in parallel using MPI in distributed memory. In the strategy presented in this work, first the point clouds are equally partitioned between the different MPI processes. Then, each process reads its corresponding part of the point cloud and creates an octree with its points. Finally, the processes calculate the points' neighborhood and their geometric descriptors and save the results in a plain text file. An analysis of the performance and efficiency of the new implementation will also be carried out based on the number of processes, using different point clouds and comparing the results with those obtained sequentially.

Summary
When it comes to protecting an organization's assets, the use of security software tools is one of the main security measures adopted by tech companies, as it allows them to monitor and analyze large amounts of information in search of suspicious activity. Among the functionalities provided by these tools is the detection of vulnerabilities in the applications installed on the devices. However, there are certain technical and economic limitations that mean that most small and medium-sized organizations do not consider an automatic detection and remediation system for these types of vulnerabilities. Currently, there are open-source solutions that allow for vulnerability detection, but the remediation of these vulnerabilities is usually not available in the free tools, or at least not in an automatic way, as seen in the study of the documentation provided by several tools specifically recommended by the organization in which this project is developed. Therefore, this work proposes a partial solution to this problem by extending the capabilities of the open-source tool Velociraptor. On one hand, methods are developed to enable the collection and analysis of the necessary information during vulnerability detection. Additionally, through an application repository and action protocols, an effective way to remediate these vulnerabilities with minimal intervention is created.

Summary
Cloud Native technologies have been gaining traction within the business world, thanks largely to the advantages they offer over their direct competition, traditional cloud computing. These, being specifically designed to operate efficiently and scalably in cloud environments, allow you to make the most of the resources available within your environment. Even so, this technological model also brings with it problems that must be faced. One of them is their ability to adapt to work demands that are constantly changing, and which can lead to application availability problems if the system is not capable of supporting said load. This work aims to study the various automatic scaling tools available to Kubernetes, giving special emphasis to the Horizontal Pod Autoscaler (HPA) and traditional metrics, in order to verify their performance against various practical cases.

Summary
Currently, the expansion of quality synonyms is a necessary task to evaluate the sensitivity of linguistic models to small alterations introduced through synonym substitution. Using knowledge graphs to query and extract quality synonyms makes this task easier. However, knowledge graphs contain a lot of implicit knowledge that cannot be directly recovered with common query languages. Along these lines, this final degree project explores a new method to successfully expand the query to the AGROVOC knowledge graph, in the domain of agriculture. Taking advantage of the hierarchical and logical context of the concepts and the lexical richness of the terms in AGROVOC, the method allows inferring the most precise category for entities not included in the KG that verify two restrictions, that they are multiword and nest other entities affirmed in AGROVOC.

Summary
The objective of this project is to develop a plant for the production of hydrazine hydrate with a mass concentration of 64 percent from ammonia and sodium hypochlorite, both in solution, using the Raschig method. The design is approached with the purpose of producing 12000T/year of product operating continuously, 330 days a year, 24 hours a day. The rigorous design of the most relevant equipment of the process is described, being the hydrazine reactor and the distillation column to obtain the product. It has been decided to address the design of a hydrazine hydrate production plant because of its current research in the energy field for its use as chemical storage of hydrogen in fuel cells due to its high hydrogen content, ease of transport and storage, in addition to the fact that the only by-product of its decomposition would be nitrogen. This is a study of current importance, since it offers an alternative to fossil fuels. On the other hand, hydrazine hydrate is currently used in various industrial fields; due to its ability to eliminate oxygen from water, it is used in high-pressure steam generators and industrial boilers, but it also has other uses, such as foaming agent for plastic foams, polymerization initiators, pesticides, pharmaceutical products, photographic chemical products or dyes. Derivatives of this component also have a great place in today's industry, such as, for example, hydrazine anhydrous, which is synthesized by the Olin Raschig method and is notable for its use as a rocket propellant. The facility is located in the north of Spain, more specifically in the industrial park of Lloreda, belonging to the Asturian city of Gijón, with the aim of facilitating the commercialization of hydrazine hydrate by sea to northern Europe and other commercial areas of interest. This document represents the Final Degree Project by means of which the students Mara Meitín Fraga and Xeila Liñayo Vicente opt for the university degree in Chemical Engineering awarded by the Escola Técnica Superior de Enxeñaría of the Universidade de Santiago de Compostela.

Summary
Drying oil is used as a finish for paints and varnishes. In this process, waste cooking oils are used in a process that involves the use of a reactor (which will be designed in detail) and several separation equipment such as distillation columns. Waste cooking oils are introduced into the process, from which palmitic acid is extracted and fed into the process battery to ultimately form a product with good drying properties. This process involves typical equipment in the field of Chemical Engineering at high pressures and temperatures to meet the proposed plant capacity of 20,000 tons/year.

Summary
The objective of this project is to design a production plant for dimethyl ether (DME) from the catalytic dehydration of methanol. Its production capacity covers 50,000 tons annually at 99.95% purity by weight, operating continuously for 24 hours a day, 330 days a year, with maintenance shutdowns accounted for. Dimethyl ether is currently a product of interest as it is a competitive substitute for existing fuels. It is a clean gas, easily liquefiable, and easy to transport. It has potential in various markets, notably in power generation, as a substitute for liquefied petroleum gas, and as an automotive fuel due to its high cetane number and lack of sulfur oxide emissions. Its production is carried out in the R-201 multitubular catalytic reactor, which operates isothermally at 320ºC, producing dimethyl ether and water. This equipment is designed by Miguel Díaz Abalo. Next, in a train consisting of two distillation columns arranged in a direct sequence, the separation and purification of the product of interest take place, as well as the recirculation of the unreacted raw material. The first distillation column, designated T-301, is the equipment through which dimethyl ether is obtained at the required purity and flow conditions, and it is designed by Saleta Martínez Tella.

Summary
galerIA is a web application that implements a multimedia gallery where users can store and organize their images and videos. The main difference from other similar applications is that galerIA implements innovative functionalities based on machine learning models on the client side. Users, in a completely transparent way and without the need for technical knowledge, can benefit from applying super-resolution to their images, filtering them by the objects that appear in them, or generating new images, without the need for a dedicated server to do so, minimizing the cost of serving the application and the required bandwidth at the expense of higher resource consumption on the client device.

Summary
BigData is one of the fastest growing fields in computer science. Because of the big amounts of data and its variety, it started to be difficult or even unfeasible to process data with tradicional techniques. Because of this, new programming models such as MapReduce and new frameworks supporting this new models appeared. Current reference framework is Spark, which enables efficient massive data processing in a reasonable time. IgnisHPC is a data processing framework partially inspired on Spark and designed to improve some of its limitations. IgnisHPC has objectives such as the unification of the BigData and HPC workloads, multiple language compatibility, MPI integration, and a container virtualization design. In this work we develop the Java implementation for some of the IgnisHPC framework modules. We indicate the limitations between Spark and IgnisHPC, and compare performance with a test program.

Summary
The objective of this project is to design a production plant for dimethyl ether (DME) from the catalytic dehydration of methanol. Its production capacity covers 50,000 tons annually at 99.95% purity by weight, operating continuously for 24 hours a day, 330 days a year, with maintenance shutdowns accounted for. Dimethyl ether is currently a product of interest as it is a competitive substitute for existing fuels. It is a clean gas, easily liquefiable, and easy to transport. It has potential in various markets, notably in power generation, as a substitute for liquefied petroleum gas, and as an automotive fuel due to its high cetane number and lack of sulfur oxide emissions. Its production is carried out in the R-201 multitubular catalytic reactor, which operates isothermally at 320ºC, producing dimethyl ether and water. This equipment is designed by Miguel Díaz Abalo. Next, in a train consisting of two distillation columns arranged in a direct sequence, the separation and purification of the product of interest take place, as well as the recirculation of the unreacted raw material. The first distillation column, designated T-301, is the equipment through which dimethyl ether is obtained at the required purity and flow conditions, and it is designed by Saleta Martínez Tella.

Summary
Pictocuentos is an application born from the desire to provide an interactive form of entertainment based on the use of classic children's literature for girls and boys with communication difficulties, such as those with Autism Spectrum Disorder (ASD). It serves as a tool that can aid their cognitive development by adapting to their needs through the use of pictograms, thus helping them better understand their environment and stimulate language-related aspects. The goal of this Final Year Project is to develop a web app platform that allows users to create their own scenes using preloaded characters and settings taken from popular children's literature. Users can contextualize the scene through dialogues translated into pictograms and can enhance the immersive experience with background music or narration through voice bots. The design, implementation, and testing processes were approached differently for the frontend and backend. Notably, the user testing was conducted by graduates of the Speech Therapy Degree at the University of A Coruña and graduates of the Double Degree in Primary and Early Childhood Education at the University of Santiago de Compostela. This feedback came from individuals experienced in working with children with ASD. The results obtained suggest that Pictocuentos can become a leisure application that caregivers of such individuals can use to teach vocabulary in a fun and familiar way, fostering creativity while working on communication skills through pictograms.

Summary
Automatic stress detection is a relevant area of research due to the growing concerns about mental health in today's society. Thanks to advances in the field of affective computing, various methodologies and systems have been investigated in this area over the years. Although numerous monitoring systems exist, evidence on the congruence of their accuracy and applicability in a test with the same characteristics is still limited and varied. Therefore, this Bachelor's thesis aims to conduct a comparative evaluation to identify common patterns, strengths and areas for improvement between two methods of stress detection: one based on physiological signals using an Empatica EmbracePlus wristband, and the other on facial expressions using the Kopernica tool. The study was set in a controlled laboratory environment, with participants interacting with a cognitive reasoning game designed to induce stress. The process was divided into several phases: a relaxation period, interaction with the game in three different modes and a perceived stress questionnaire. Several key objectives were achieved. First, according to the EDA signal, it was established that the serious game used is a valid stress inducer, generating an increase in measured stress levels. Moderate congruence was found between the two detection methods, although with some discrepancies in their sensitivity to the complexity of the game tasks. The method based on physiological signals was shown to be more sensitive to slight variations in stress levels compared to facial expressions. Users were found to be unaware of their actual stress levels. Furthermore, it was concluded that reducing the resolution of the video impacts the accuracy of stress detection by Kopernica, with 640x360 being the minimum acceptable resolution. The results provide a clearer understanding of the strengths and limitations of each method, suggesting the need for specific adjustments in data processing to improve the accuracy and consistency of measurements. It also highlights the importance of extending the research to other emotions measured by Kopernica and to different populations to observe the manifestation of stress at different life stages.

Summary
This work tackles the partial pressure of carbon dioxide in the ocean surface prediction problem for carbon flux estimation. The set of oceanic data used comes from different satellites and oceanographic investigators organizations. To this end, the results of training nine different regression models with this set of data and with three other subsets of data created from the global set delimiting the geographic regions of the Atlantic, Indic and Pacific oceans were compared amongst them. The compared regression models were Random Forest, ExtraTrees, the method of the nearest neighbours, the support vectors machine, Gradient Boosting, Adaptive Boosting, CatBoost, XGBoost and LightGBM. After the analysis of the model comparison for each dataset, it was determined that the one which offered better results in the four cases was the ExtraTrees model, so its hiperparameters of number of estimators and maximum depth were adjusted to optimize the model’s output for each case. Once these models were adjusted, predictions using each dataset were made and files in the netCDF format were generated both for the input datasets and the sets of predicted data.

Summary
Due to the inexorable advance of the Internet, efforts to make it a safe place for everyone are increasingly necessary. One of these efforts is the abuse email boxes of companies dedicated to provide Internet services (ISPs). These abuse mailboxes aim to offer an effective way to communicate with the company about misuse perpetrated from their network. The high influx of reports received in these mailboxes forces such companies to seek efficient ways to manage them. It is from this need that this work arises, as its main objective is the development of a system for the efficient and proper management of the abuse mailbox of the company MásMóvil. To achieve this, on the one hand, we must automate the classification of received emails, as well as their response if necessary, and on the other hand, we must streamline the analysis of the reports themselves, especially the analysis of reported IP addresses. Both parts were successfully developed, as the designed method significantly optimise the task, saving the company significant effort and resources. The main tool for the work has been Microsoft Copilot, an artificial intelligence assistant recently released to the market, whose contributions and performance were to be tested. Additionally, for the completion of the process, tools such as Power Automate and PrivateGPT, an open-source project that integrates the advantages of chatbots with a locally private environment, were used. The Microsoft assistant ultimately played a less relevant role than expected, being surpassed in certain important aspects by PrivateGPT when it came to analyzing IPs. Power Automate, an application from the Microsoft 365 suite, took the lead role, as it handled practically all of the automation tasks.

Summary
Since the introduction of multicore processors, shared memory parallelization has been essential for improving the performance of computer systems by dividing tasks into smaller tasks that can be executed simultaneously on multiple processors or cores. Speculative parallelization allows this technique to be applied to problems with complex or unpredictable data dependencies, enhancing efficiency and reducing waiting times. In this work, we analyze the performance of SpecLib, an automatic speculative parallelization library, evaluating its effectiveness in various scenarios, varying factors such as the number of threads and the size of code blocks. The work aims to identify the factors that can affect the library's efficiency in different scenarios.

The process includes a pre-conditioning stage, where sulfuric acid in the liquid phase will be used to protonate the acetic acid that will be used in the reactor, with sulfuric acid playing a crucial role in the synthesis of the reaction as a catalyst. This reaction will take place in the tubular reactor R-101, designed by Brais Queiro Lamas. At the reactor outlet, two separation columns, T-201 and T-202, will be used respectively. The first is intended for the recovery of sulfuric acid, and the second to concentrate the peracetic acid to obtain the desired product. The T-202 column will be designed by Manuel Antonio Castro Pereiras. This project is presented as a Final Degree Project through which the students Manuel Antonio Castro Pereiras and Brais Queiro Lamas aim to obtain the Degree in Chemical Engineering awarded by the Higher Technical School of Engineering belonging to the University of Santiago de Compostela.

Summary
In recent years, various deep learning classification models have been proposed, adding to the existing methods for classifying multispectral remote sensing images. Within this framework, in this work, a conditional generative adversarial network (GAN), based on the StyleGAN2 model architecture, was adapted to the problem of classifying multispectral remote sensing images. Subsequently, a study was conducted on the network's capability to both generate and classify high spatial resolution multispectral images corresponding to Galician rivers. Finally, the results achieved with this classification model were compared to other models used in multispectral remote sensing problems. It was observed that the conditional StyleGAN2 achieves results close to other classification schemes that do not use generated datasets, such as convolutional neural networks, but falls short of methods specifically designed to generate samples for classification problems with imbalanced classes, such as ResBaGAN.

Summary
Ethyl acetate is a chemical compound used as a solvent in a large number of industrial processes, as well as an additive in both the food and cosmetic sectors. The plant's capacity is 25,000 tons per year since production in Spain is not of high tonnage. Ethyl acetate is produced through the esterification reaction between acetic acid and ethanol, with water obtained as a byproduct of this reaction. Additionally, as a sustainable alternative, the option of using bioethanol as a raw material is proposed. Joel Fernández García is responsible for designing the heterogeneous catalytic reactor, while Carlos Fuentes Varela designs the distillation column where the product is obtained. The separation train consists of three distillation columns and one liquid-liquid extraction unit.

Summary
Differential forms constitute a highly relevant mathematical object in Differential Topology and Differential Geometry with important applications to Physics. The aim of this work is to study different uses of differential forms and to show how they allow for effectively addressing numerous problems. First, basic notions about fiber bundle theory will be given, which are fundamental to address the rest of the work. Following this, the concept of orientation of a manifold will be defined, and a brief introduction to semi-Riemannian manifolds will be presented. This will allow us to generalize basic concepts of vector calculus to differentiable manifolds. Next, integration on manifolds will be studied, and the generalized Stokes' Theorem will be proven. These concepts will also be addressed for the case when the manifold is non-orientable. Finally, de Rham cohomology and its main properties will be studied. In addition to all this, applications to electromagnetism of the studied concepts will be included throughout the work. Specifically, Maxwell's Equations will be formulated using differential forms, Stokes' Theorem will be used to give an integral version of the equations, and de Rham cohomology will be used to illustrate wormholes and magnetic monopoles, physical phenomena never detected experimentally.

Summary
Object detection is one of the main challenges addressed in the field of Computer Vision. Traditional detectors require a large amount of labeled images for training. This presents a significant limitation, as image annotation is costly and data availability is often limited. In this context, semi-supervised learning for object detection emerges, addressing the scenario where there are few labeled images but a large number of unlabeled images. This work falls within this area and focuses on the study of Teacher-Student architectures. Specifically, the Unbiased Teacher v2 detector is studied. The aim of this work is to study different techniques that are beneficial in other learning contexts and analyze their applicability to this detector. Specifically, the following proposals will be analyzed: incorporation of modules typical of few-shot architectures (specifically the Gradient Decoupled Layer (GDL) and Prototypical Calibration Block (PCB) proposed in the DeFRCN detector); replacement of the fixed threshold strategy for filtering pseudo-labels with a flexible threshold strategy; and the use of a label assignment strategy based on Optimal Transport Assignment (OTA). The experiments conducted show that the use of GDL is beneficial for the detector's performance. Additionally, although the other proposals did not improve the detector, the experimentation revealed several challenges that arise when adapting these strategies to a detector with the characteristics of Unbiased Teacher v2. This information may be relevant for future analyses of the problem.

The subject of Cybersecurity taught in the Degree in Computer Engineering at the University of Santiago de Compostela's main objectives are to know and understand the main attacks that can receive a computer system. For the explanation and understanding of the different existing attacks, practices are carried out using a large number of virtual machines, many of them with numerous vulnerabilities. These practices have to be developed in an isolated and secure environment. Therefore, in this work we have implemented a networked system with a virtualization server that allows to configure and deploy all the virtual machines, a network has been configured to provide the required connectivity between the different systems, and several tests and pentesting exercises have been executed that can be performed in this safe and controlled environment.

Summary
In the last ten years, the popularity, capability, and investment in Artificial Intelligence techniques based on deep learning has increased considerably. Large Language Models (LLMs) are currently the most widely spread tools for text generation in a wide range of tasks. The size of these models and the corpus with which they are trained have turned them into large knowledge bases. One of the most promising lines of work focuses on using these models as study aid tools. An example of this trend could be Google Workspaces for Education. Job interviews are an integral part of our lives, and surprisingly, there aren't many interactive tools to help in their preparation. This bachelor's project titled AIWantTheJob is created to explore the use of LLMs as learning aid tools in order to cover this detected gap. AIWantTheJob aims to develop a job interview simulator to prepare candidates for a specific position. Using Deep Learning and NLP techniques, the system generates realistic and personalized interview scenarios that provide real-time assessments to improve interviewees' skills. To enhance the results of the responsible LLM, this work proposes a RAG (Retrieval-Augmented Generation) that generates and provides access to the specific knowledge base of the job position for which the user is preparing to interview. Additionally, a parallel tool called Nemo Guardrails is used, which serves, among many other things, to define conversation flows between the person and the LLM. The system has been implemented as an app that can be deployed in virtualized environments quickly and requires low-cost computing resources (considering the standard requirements of AI-based applications). Furthermore, the application is equipped with realistic deployment techniques to simulate a real production environment. Beyond the business case of the interviewer, the created system allows any developer to implement chatbots on other topics with specific actions, requiring minimal time investment and great ease. The proyect provides a chatbot that adequately performs the three proposed tasks (asking, evaluating, and simulating responses), adhering well to the context and hallucinating relatively little. Moreover, we can conclude that the results can be improved by using a more intelligent model, which would require more computational resources than those available during the project.

Summary
This end-of-degree project focuses on the development of a system that allows the construction and exploitation of a knowledge graph from emotional word bases. For this purpose, a vocabulary will be created to manage these word bases, and a set of procedures to popularise the knowledge base in a (semi)automatic way. Finally, a web application will be developed that consumes such structured data and allows its management and downloading by other users/scientists based on a set of defined filters. The main contribution, therefore, will be the updating of the previous system (https://www.usc.gal/pcc/app/emofinder/) through the use and exploitation of semantic technologies to ensure the F.A.I.R. (findable, accessible, interoperable and reusable) principles in the integrated word bases.

2-methoxy-2-methyl-heptane (MMH) is used in various fields, mostly as a gasoline additive or pharmaceutical intermediate. The capacity of the plant is 30 000 tonnes per year as both traditional applications and new chemical grade alternatives are not large tonnage applications. MMH is produced from methanol and 2-methyl-1-heptene. As a sustainable alternative, green methanol from a nearby plant is proposed. Pablo Rodríguez-Villamil Seoane is in charge of the design of a packed distillation column (T-203). Raúl Veiga Moo is in charge of the design of a catalytic heterogeneous fixed bed reactor (R-101). Finally, Hugo Vidal Cabanelas is in charge of the design of a distillation plate column (T-202).

Summary
Training object detection and segmentation models represents a considerable challenge in the field of computer vision. This process not only requires extensive datasets of annotated images, which may not be available for all classes of objects of interest, but also demands significant computational resources. The need for image annotation, high-performance GPUs, and powerful computer equipment implies a substantial investment in terms of time, economic resources, and human effort that not everyone can address. In this context, the development of models that, after a single initial training, are capable of detecting, segmenting, and classifying any type of object, can be a great advantage. This approach, known as zero-shot panoptic segmentation, seeks to address some of the current limitations of traditional models, which can only classify objects of classes with which they have been trained. To date, this area of research has been relatively unexplored due to its difficulty, both due to the lack of annotated data and the challenge of generalizing to unknown classes. The recently published CONCAT model is currently the only work in this field, and its results suggest that there is still considerable room for improvement. In order to improve the current state of the art in this task, this work proposes a new zero-shot panoptic segmentation algorithm, achieving significantly better results than CONCAT.

Summary
This essay focuses on the design of a production plant for 378.79 kg/h of copper sulfate pentahydrate from copper scrap. The process has an irreversible chemical reaction, which will be carried out in a continuous stirred tank reactor with an aeration system. The product resulting from the reaction is copper sulfate, which will be transferred to a crystallizer to obtain the desired product. The crystals formed will be separated from the rest of the mother solution through a filtration process that will be carried out in tandem with a continuous washing process to remove the acidity of the product. This entire process culminates in a drying process through which the excess water will be removed to give rise to a copper sulfate pentahydrate product with 5% humidity.

Summary
Life Story Books are widely used in reminiscence therapy for treating older adults with dementia, as they help stimulate memory, improve communication, and strengthen personal identity. Emobook, an Android application designed for tablets, assists caregivers in preparing these stories and allows the addition of elements such as videos or audio recordings. It also facilitates the capture of emotional responses associated with the memories, enabling the tracking of therapy sessions. During this project, a significant evolution of this application was undertaken, introducing new functionalities and improvements to expand its capabilities and enhance the user experience. Among the main improvements was the transition from local storage to cloud storage, making it easier to access and edit memories from any tablet with an internet connection, ensuring the necessary accessibility and flexibility. Additionally, the application was enhanced with the ability to add audio from Spotify, allowing caregivers to easily include meaningful music in the life stories. Features were also introduced to allow the transfer of memories between groups and to log attendance and disconnections, as well as the ability to modify configuration options and edit stories during therapy sessions directly from the viewing interface. These enhancements have optimized the Emobook application, facilitating caregivers' personalization and effective management of life stories, thereby improving the care and quality of life for older adults with dementia.

Summary
Process mining is a discipline focused on the analysis of the execution of business processes. Its objective is to obtain a detailed, accurate and actionable vision of these processes with the aim of improving their efficiency, conformity, performance and predictive capacity. It is, therefore, a critical tool today in many industrial and financial fields, but also in other areas less related to this technology such as health and education. However, the data extracted from the execution of such processes are not usually perfect and generally include problems derived from data capture, either by humans or by automated systems. This Final Degree Project (TFG) will focus on one of these problems, keys for mining techniques to maintain a high degree of effectiveness, integrity and efficiency: the detection of anomalies. Recently, due to the limitations of the classical methods of anomaly detection, deep-learning techniques have been employed. The latter offer significantly higher capabilities, allowing more accurate and efficient detection of anomalies compared to traditional approaches. These techniques include autoencoder-based architectures, a type of neural network that has proven to achieve very competent results in the identification of anomalies, according to the existing literature on the problem. These proposals are based on taking advantage of the great capacity of the autoencoder for the reconstruction of the input data: as normal data are more frequent, the trained model tends to reconstruct them with a lower error than the anomalous data, which allows us to detect the latter. This work proposes a new architecture based on one of the variants of the autoencoders: the CVAE (Conditional Variational Autoencoder). This proposal seeks to achieve a higher performance in the detection of anomalies compared to the approximations of the state of the art. In addition to the design process of the architecture, efforts have also focused on carrying out an appropriate preparation of the data and defining an appropriate strategy for the identification of anomalies. This proposal has been validated using 24 records of events associated with 6 synthetic processes of different complexity, achieving results higher than the state of art in deep learning approaches in the field.

Summary
This Bachelor's Thesis addresses the challenge of predicting the respiratory signal from electrocardiogram (ECG) signals using advanced machine learning techniques, specifically Recurrent Neural Networks (RNN) and Neural Ordinary Differential Equations (ODE-RNN). Given the irregular nature of biomedical time series, a methodology is proposed that not only focuses on the ECG signal directly but also incorporates a derived signal known as the warping signal, which captures significant temporal variations between heartbeats. This approach aims to improve the accuracy of predictions by providing the model with a richer representation of the underlying information in biomedical signals. Two differently trained models are developed and evaluated to see the influence of the warping signal on training for the prediction of the respiratory signal. Through this study, the ability of ODE-RNNs to effectively handle irregular temporal data, a critical aspect in the biomedical field, is explored. This work not only contributes to the field of time series processing and artificial intelligence but also lays the groundwork for future research in the prediction and analysis of complex biomedical signals, opening new possibilities for health monitoring and medical diagnosis.

Summary
Data mining for psychological disorders has been a prolific area of study in recent times. With the exponential growth of social media activity, the number of messages posted by users can provide valuable insights into their mental health status. On the other hand, pathological gambling is being targeted by many Western governments due to its rise with the advent of new technologies, especially among adolescents. The main objective of this work is to explore and analyse messages from an online gambling forum in order to detect signs, behavioural patterns or symptoms of pathological gambling. For this purpose, different data mining techniques and search models will be tested in order to extract statistical data and phrases reflecting symptoms of gambling disorder. Finally, the results obtained will be discussed, evaluating the effectiveness of the techniques applied and the data they reflect.

Summary
The motivation for this work comes from the lack of knowledge, on the part of the city councils of the large Galician cities, of the state of traffic in most of their streets. They only have information about those in which sensors have been installed. Therefore, it is proposed to create an artificial intelligence model capable of determining what the traffic is like on these streets. It is proposed to create a Machine Learning model based on LSTM (Long Short Term Memory) neural networks that is capable of determining the traffic status at any point in the city of Santiago de Compostela. We categorize the traffic state into 4 classes: free, fluid, congested and traffic jam. This traffic categorization is made from the two measurements obtained from the sensors already installed in the city. These measures are the flow or flow of cars and the occupancy or percentage of occupancy. An algorithm is also implemented that allows knowing the distance from a point to the other sensors along the shortest path, based on Dijkstra's algorithm. In this way, we seek to determine how strong the correlation will be between the selected point and the sensors. This solution will be an efficient, reliable and economical alternative for the municipalities of Galicia, compared to the installation of more sensors that monitor traffic.

Summary
In recent years, technological advances have enabled the use of multidimensional images in a wide range of contexts and applications. In many of these cases, Unmanned Aerial Vehicles (UAVs) with sensors capable of capturing images containing reflectance information from different bands of the electromagnetic spectrum are used. Problems associated with processing this type of image, such as registration or alignment, have become necessary for a multitude of applications of these images, such as change detection or the analysis of the evolution of foreign vegetation. The registration of two multidimensional images involves finding a geometric transformation (scale, angle, and rotation) that allows aligning images captured in the same area by using all the available spectral information to improve the quality of the registration. These images may be obtained at different time instances, with different perspectives or lighting conditions. Difficulties that, combined with the conditions of capture from UAVs, result in high variability between the images, despite having the same number and properties of spectral bands. These conditions are the main challenges of this work, which seeks to solve the problem of efficient registration of high spatial resolution multispectral multitemporal images of river ecosystems in Galicia. The aim is to align images captured in 2023 and 2024 with respect to images obtained in 2018 for the same areas. Given the large size of the images, portions of the complete images will be used. Additionally, due to the difficulties mentioned earlier in the registration process, a two-level process will be proposed: initial registration and refinement. First, an analysis and selection of the different registration algorithms available in the state of the art, capable of registering multi-band images, particularly hiperspectral ones, has been carried out. The selected methods have been implemented and evaluated on high spatial resolution multispectral multitemporal images of land cover. In the proposed experimentation, different tests have been conducted: evaluation of accuracy for different image sizes, with different numbers and types of natural and artificial elements, and with different levels of overlap or visual coincidence. The main contribution of this work is to address the registration of images that were captured as part of a project carried out by the research group in which this Final Degree Project was developed and which, therefore, suffer from all the problems typical of real images. For example, the pairs of images being registered correspond to different years and were captured by sensors on board drones, so the capture conditions between images from different dates are very different, both in terms of climate and drone inclination or altitude. Furthermore, it addresses the application of methods adapted to images with hundreds of bands and medium spatial resolution to images that have only five spectral bands but very high spatial resolution. A process was designed to systematically address image registration, and it was determined which algorithms are most suitable for both initial registration and final refinement. The evaluation is done both in terms of accuracies obtained and resilience to image overlaps and variations, as well as in terms of execution time.
In recent years, technological advances have enabled the use of multidimensional images in a wide range of contexts and applications. In many of these cases, Unmanned Aerial Vehicles (UAVs) with sensors capable of capturing images containing reflectance information from different bands of the electromagnetic spectrum are used. Problems associated with processing this type of image, such as registration or alignment, have become necessary for a multitude of applications of these images, such as change detection or the analysis of the evolution of foreign vegetation. The registration of two multidimensional images involves finding a geometric transformation (scale, angle, and rotation) that allows aligning images captured in the same area by using all the available spectral information to improve the quality of the registration. These images may be obtained at different time instances, with different perspectives or lighting conditions. Difficulties that, combined with the conditions of capture from UAVs, result in high variability between the images, despite having the same number and properties of spectral bands. These conditions are the main challenges of this work, which seeks to solve the problem of efficient registration of high spatial resolution multispectral multitemporal images of river ecosystems in Galicia. The aim is to align images captured in 2023 and 2024 with respect to images obtained in 2018 for the same areas. Given the large size of the images, portions of the complete images will be used.

Summary
Federated learning (FL) emerges as a promising solution for collaborative development of artificial intelligence models without compromising the privacy of distributed data. However, data heterogeneity, diverse local learning methodologies, and the presence of malicious attacks pose significant challenges that hinder the effectiveness and security of the global model. This work explores solutions to enhance the robustness of federated learning, not only in scenarios with high data heterogeneity but also in environments affected by malicious attacks aiming to significantly degrade the performance of the global model. Two main lines of work are examined to mitigate the impact of divergent clients: robust aggregation and active defense techniques. Moreover, a new methodology within the field of adapted personalized federated learning is introduced, employing local personalized models alongside a global model, allowing for more precise adaptation to the specific conditions of each client. Empirical studies, conducted in both synthetic and real environments, validate the effectiveness of the proposed strategies against attacks and demonstrate how proper management of heterogeneity and anomaly detection can significantly improve the performance of the federated model. This work, in addition to contributing to the existing literature on federated learning, also offers a practical perspective for its application in robotics, where data diversity and task specificity present unique challenges.

Summary
Demonstration level facility of production of acrylic acid from glycerol as a first approach to the industrial scale development, as the maximum level of maturity achieved was the pilot plant scale. The traditional process for the obtention of acrylic acid is basen on the propylene oxidation, obtained directly from the combustion of fossil fuels. Due to the needs of the industry to support the energetic transition, it is necessary to search for alternatives which lessen the dependence on these type of non-renewable resources. Because of this, this work is based on the selective conversion of glycerol, a coproduct generated in the manufacture of biodiesel, which is obtained from vegetal oils and animal fats. Glycerol will react to produce acrolein in a first reactor, which will be converted into acrylic acid in a second step. This product will be purified by the usage of a flash drum, an absorption column, liquid-liquid extraction and a sequence of distillation columns. In terms of design, the student Daniel Fins Simón developes an hetereogeneous catalytic reactor in gas phase, while the student Pablo Carrera developes a liquid-liquid extraction unit.

Summary
n the field of medical image analysis, the classification of dental X-rays is crucial for detecting pathologies, as it allows each image to be labeled with the presence or absence of a specific condition. Recently, convolutional neural networks (CNNs) have proven effective in this area. This thesis develops a model based on ResNet architectures to classify panoramic dental X-rays. Using a dataset provided by the OSRG from the University of Santiago de Compostela, which includes 8 classes of pathologies, data augmentation and class balancing techniques were applied to address class imbalance. Various ResNet architectures were explored, and hyperparameters such as batch size and image resolution were adjusted. This report details the experiments conducted, the results obtained, and the conclusions and potential extensions of the work.

Summary
In this work, we will consider the dynamics of an electron beam guided by an axially symmetric periodic magnetic field. This type of mechanism is known as an electron gun or microwave valve and is a part of many scientific, industrial, and domestic electronic devices. Its dynamics can be modeled using the Mathieu equation, which is a second-order equation with singularities and can be treated as a particular case of the Hill equation. Thus, we will focus on modeling the phenomenon and describe some results that guarantee the existence of periodic solutions with constant sign.

Summary
Isopropyl alcohol (IPA) is a product in progressive growth in the world market, both in the medium and long term. Among the many uses of this compound, its use in the pharmaceutical, cosmetics, cleaning, automotive and industrial sectors stands out. The process carried out consists of the production of IPA from acetone. A hydrogenation reaction is carried out, in which the reactants are acetone (liquid phase) and hydrogen and the products are isopropyl alcohol, propene and water. The IPA is then separated and is obtained in a very pure concentration. To take advantage of the by-products, hydrogen is recirculated, and a fuel is also obtained from the by-products obtained. The plant would be designed to obtain 97,000 tons of IPA at 97% purity and 29,000 tons of azeotropic IPA. It should be noted that this year (2023) the construction of an IPA production plant from renewable materials has been confirmed in Huelva, Spain. The company carrying out this project is CEPSA and the plant will be operational from 2025. Finally, the distribution of the equipment design will be the reactor with Javier Bermudez and the distillation column for Alicia Gomez.

Summary
Ethyl acetate is a chemical compound used as a solvent in a large number of industrial processes, as well as an additive in both the food and cosmetic sectors. The plant's capacity is 25,000 tons per year since production in Spain is not of high tonnage. Ethyl acetate is produced through the esterification reaction between acetic acid and ethanol, with water obtained as a byproduct of this reaction. Additionally, as a sustainable alternative, the option of using bioethanol as a raw material is proposed. Joel Fernández García is responsible for designing the heterogeneous catalytic reactor, while Carlos Fuentes Varela designs the distillation column where the product is obtained. The separation train consists of three distillation columns and one liquid-liquid extraction unit.

Summary
This Bachelor's Thesis explores the semantic classification of biomedical texts using the generative language model Llama3, aiming to improve access to information in biomedicine through MeSH descriptors. The proposed method consists of different stages, the first being the preprocessing of the MeSH ontology obtained through BioPortal. Then, biomedical abstracts annotated with generic categories are selected and prepared, ensuring a representative sample for subsequent classification. The methodology involves the implementation of an algorithm based on a zero-shot approach of the Llama-3 model, developing specific prompts and normalizing the generated responses to ensure consistency. Finally, exhaustive tests are conducted, applying standardized metrics such as precision, recall, and F-measure to evaluate the performance of the classification technique. The results show that Llama-3 surpasses weak supervision methods in terms of precision, although it presents challenges in terms of recall. The discussion includes a detailed analysis of specific descriptors, identifying patterns and proposing improvement strategies. In conclusion, the effectiveness of generative language models with closed queries is highlighted, as well as the importance of future optimizations in terms of computing capacity and prompt engineering techniques. This work lays the foundation for future research in the semantic classification of biomedical texts, suggesting expansions to optimize the obtained results.
