description: Urban rivers are critical ecosystems increasingly threatened by pollution. Effective water quality monitoring and contamination assessment are essential for informed management decisions. The Santiago River, a key hydrologic system in Mexico, has become one of the country’s most polluted rivers, posing significant ecological risks and public health concerns for nearby communities. This study underscores the urgent need for comprehensive environmental evaluation and enhanced monitoring approaches. Chapter one introduces the motivation behind monitoring water quality in highly polluted rivers, presenting the problem statement and contextual background of the Santiago River basin. It outlines the research question and provides an overview of the proposed dual-lens approach: combining water quality analysis via machine learning algorithms with metagenomic characterization of contamination effects. Key contributions of this work to the field are also highlighted. Chapter two reviews global monitoring strategies from highly polluted rivers, focusing on nine rivers across developed and developing countries to offer a comparative perspective on water quality management needs. In Chapter three, regression and classification machine learning models are developed to predict the Santiago River Water Quality Index (SR-WQI), designed as complementary tools to strengthen the current monitoring program. Chapter four analyzes the historical water quality patterns of the Santiago River to identify the most variable and representative data for training machine learning models. This chapter also reveals that redundant data can hinder model performance by leading to overfitting. Chapter five investigates spatial variations in the microbial composition of Santiago River sediments and examines correlations with water quality. Using high-throughput sequencing, potential microbial biomarkers were identified and impacts of physicochemical parameters and heavy metals on microbial communities were assessed. Finally, chapter five highlight the main findings of this thesis and covers some limitations, perspectives for future research and final remarks.

description: Hay un aumento en la detección de cáncer renal en las últimas dos décadas. El tamaño tumoral promedio reportado en la literatura es de 3 a 4 cm. Estos tamaños pequeños ofrecen tratamientos menos agresivos, cirugías parciales y mejor sobrevida global al cáncer. El Carcinoma de Cálulas Renales es el tumor renal más común representando al 85% de las veces. La única posibilidad de curar cáncer de riñón es quirúrgica. El cáncer de riñón es considerado el tumor más letal entre los tumores genitourinarios. Las metástasis sincrónicas, corta sobrevida libre de enfermedad y corta sobrevida cáncerespecífica son comunes con tumores mayores de 7 cm. La característica principal de la patología es ausencia de síntomas. 40% de pacientes presentarán metástasis al diagnóstico. Con esto nos dimos a la tarea de investigar si los tumores de pacientes con cobertura pública son de mayor diámetro, que los tumores de pacientes con cobertura de salud privada. Realizamos este estudio transversal, multicéntrico y comparativo que incluye pacientes con diagnósticos de cáncer de riñón tratados quirúrgicamente en hospitales de alto volumen del área metropolitana de Monterrey, México. Los hospitales incluidos fueron la Unidad Médica de Alta Especialidad IMSS No. 25, el Hospital Regional ISSSTE; y el Hospital Metropolitano de los Servicios Estatales de Salud de Nuevo León representando a los pacientes bajo cobertura pública y se compararon con un grupo de pacientes con cobertura privada representados por pacientes de los Hospitales TEC Salud: Hospital San José de Monterrey y Hospital Zambrano-Hellion y del Hospital Ángeles Valle Oriente. Se incluyeron 629 expedientes completos de pacientes con cáncer renal con los reportes de patología. Además se evaluaron histología tumoral, clasificación TNM y estadios tumorales, factores de riesgo, así como abordajes y técnicas quirúrgicas. Se utilizaron pruebas paramétricas U de Mann-Whitney para comparación de media de tamaños tumorales, Chi cudrada para variables cualitativas, y t-student para la edad entre grupos. Se demostró diferencia estadística entre los tamaños tumorales de ambos grupos. Los tumores de pacientes con cobertura de salud pública tuvieron mayor diámetro que los pacientes bajo cobertura privada. Llama la atención que en ambos grupos el tamaño tumoral supera al diámetro actual descrito en la literatura. Lo cual puede signifcar que no se están detectando tan frecuente como se debiera, a los paciente con tumores asintomáticos de tamaños más pequeños en ninguno de los dos grupos.

description: Grapevine is a highly economically important crop in Mexico. However, it can be affected by several pathogens, including viruses that can cause significant crop losses. It is important to identify early the infected plants to manage the disease correctly and prevent economic losses. Traditional detection methods have drawbacks, such as limited sensibility and accuracy. Digital PCR (dPCR) is an innovative method that claims to be more sensitive and reproducible than the routine method for virus identification: quantitative PCR (qPCR). This study assesses reverse transcription dPCR (RT-dPCR) as a method for the detection and quantification of RNA grapevine viruses focusing on grapevine virus A (GVA), grapevine fanleaf virus (GFLV), grapevine leafroll-associated virus 3 (GLRaV-3), and grapevine Pinot gris virus (GPGV). This assessment was performed using positive controls and comparing the limit of detection (LoD) results of RT-dPCR against the results obtained by RT-qPCR. ANOVA results showed that the PCR technique (RT-dPCR or RT-qPCR) and the virus (GVA, GLFV, GPGV, and GLRaV-3) were statistically significant in the results of the comparison of LoD. Furthermore, the replicates were non-significant according to ANOVA, showing high repeatability in both RT-qPCR and RT-dPCR. Tukey test demonstrated that RT-dPCR is significantly more sensitive than RT-qPCR, with a statistically reliable difference of 95% trust, especially in low-viral-load viruses such GPGV, which detection showed also to be statistically different than the other viruses. Additionally, a field study was performed to identify the presence or absence of each virus in 45 grapevine samples evaluated with RT-qPCR and RT-dPCR. Several false negative results were generated by RT-qPCR, which only reported positive results to 62.5% of the GVA infected samples, 85.7% of the samples contaminated with GLRaV-3, 38.9% of GPGV positive samples and for GFLV only 12.5% of the infected samples were identified. These results confirm the effectiveness of RT-dPCR as a sensitive method for RNA virus detection in grapevine, enabling early diagnosis and optimal management of viral infections in grapevine crops.

description: Signal classification in environments with low signal-to-noise ratio (SNR) presents a significant challenge across various fields, from industrial monitoring to biomedical appli cations. This work explores a novel methodology aimed at improving classification accuracy in such conditions, using EEG-based Brain-Computer Interfaces (BCIs) for inner speech decoding as a case study. EEG-based Brain-Computer Interfaces (BCIs) have emerged as a promising technology for providing communication channels for individuals with speech disabilities, such as those affected by amyotrophic lateral sclerosis (ALS), stroke, or other neurodegenerative diseases. Inner speech classification, a subset of BCI applications, aims to interpret and translate silent, inner speech into meaningful linguistic information. De spite the potential of BCIs, current methodologies for inner speech classification lack the accuracy needed for practical applications. This work investigates the use of inter-trial coherence (ITC) as a novel feature extraction technique to enhance the accuracy of in ner speech classification in EEG-based BCIs. The study introduces a methodology that integrates ITC within a complex Morlet time-frequency representation framework. EEG recordings from ten participants imagining four distinct words (up, down, right, and left) were processed and analyzed. Five different classification algorithms were evaluated: Ran dom Forest (RF), Support Vector Machine (SVM), k-Nearest Neighbors (kNN), Linear Discriminant Analysis (LDA), and Naive Bayes (NB). The proposed method achieved no table classification accuracies of 75.70% with RF and 66.25% with SVM, demonstrating significant improvements over traditional feature extraction methods. These findings indi cate that ITC is a viable technique for enhancing the accuracy of inner speech classification in EEG-based BCIs. The results suggest practical implications for improving communica tion and navigation capabilities for individuals with ALS or similar conditions. This work lays the foundation for future research on phase-based feature extraction, opening new avenues for understanding the neural mechanisms underlying inner speech and advancing BCI systems’ accuracy and efficiency

description: A growing body of research has demonstrated negative effects of sexualization in the media on adolescents' body image, but longitudinal studies and research including interactive and social media are scarce. The current study explored the longitudinal associations of adolescents' use of sexualized video games (SVG) and sexualized Instagram images (SII) with body image concerns. Specifically, our study examined relations between adolescents' SVG and SII use and appearance comparisons, thin- and muscular-ideal internalization, valuing appearance over competence, and body surveillance. A sample of 660 German adolescents (327 female, 333 male;M-age = 15.09 years) participated in two waves with an interval of 6 months. A structural equation model showed that SVG and SII use at Time 1 predicted body surveillance indirectly via valuing appearance over competence at Time 2. Furthermore, SVG and SII use indirectly predicted both thin- and muscular-ideal internalization through appearance comparisons at Time 1. In turn, thin-ideal internalization at Time 1 predicted body surveillance indirectly via valuing appearance over competence at Time 2. The results indicate that sexualization in video games and on Instagram can play an important role in increasing body image concerns among adolescents. We discuss the findings with respect to objectification theory and the predictive value of including appearance comparisons in models explaining the relation between sexualized media and self-objectification.

description: Depression is a mental disorder that affects millions of people worldwide, but a significant portion of the affected people don’t receive adequate treatment. There has been an increasing interest from researchers to detect this condition through social media posts in order to prompt for early treatment. However, most of the research has been focused on the Caucasian Western English-speaking population, limiting the applicability of their findings across diverse cultural contexts. While research has shown the use of nonverbal cues to convey sentiment, their role on depression detection remains under-explored. This thesis aims to assess the effect of nonverbal cues, specifically capitalization and character repetition, on depression detection using datasets both in English and Spanish. This effect was explored through three existing datasets. The first dataset included a collection of Reddit posts and comments in the English language and was selected to assess the effect on a dataset coming from one of the most reputable mental health competitions in Natural Language Processing. The second dataset consisted of a collection of Spanish- language messages from Telegram to verify whether findings in the English language would hold for Spanish. The third dataset, also built from Reddit posts, was used to analyze the impact of these features when classifying by depression severity levels rather than binary labels. Four classifiers were used throughout this research: Logistic Regression, Random Forest, Support Vector Machine, and Neural Network. Overall, the impact of capitalization and character repetition for depression detection was found to be minimal. These features had the most effect on English Reddit data with binary labels, while showing limited impact on Spanish data or when classifying by severity levels. Additionally, models using only character repetition outperformed those relying on capitalization features.

description: Digitalization has reshaped work and education, making Digital Skills essential for success in technology-driven environments. Despite their importance, few studies have evaluated Digital Skills as potential job resources that can help manage job stressors and support Psychological Detachment. This doctoral thesis addresses this gap in the literature through four studies. The first study reviewed the interplay between Digital Skills and Well-being, suggesting that these skills may act as a resource that promotes well-being and mitigates stress. The second study evaluated the psychometric properties of the Spanish version of the Digital Self-Efficacy scale, grounded in the DigComp framework, to assess the Digital Skills in Spanish-speaking workers. The third and fourth studies applied the Stressor-Detachment Model to explore whether Digital Skills can reduce the effect of job stressors on Psychological Detachment in digital work environments. Study 3 focused on workers in Ecuador, while Study 4 extended the analysis to university educators using a scale designed for educational contexts. The results showed that Digital Skills help workers and educators manage stress and support mental detachment from work. Some unexpected findings, such as certain stressors being positively linked with Psychological Detachment, suggest that further research is needed to understand stress responses in digital workplaces.

description: Purpose: This aim of this tutorial was to review assessment tools for speech-language pathologists working with Urdu speakers in the United States.Method: We outlined cultural and linguistic considerations for speech-language pathologists to consider when assessing Urdu speakers. We also reviewed available Urdu-language tests for pediatric and adult populations by their assessment area and evaluated whether they had been validated for Urdu speakers.Results: Speech-language pathologists should consider the impact of cultural and linguistic differences when planning assessment. In particular, many Urdu speakers are Muslim; hence, clinicians unfamiliar with the religion should open communication with clients about assessment preferences. Testing instruments covering the major areas of speech-language pathology are available for Urdu speakers in the United States.Conclusions: Speech-language pathologists can use the tools presented in this tutorial to evaluate both body impairments for Urdu speakers and the impact on an individual’s participation.

description: AISI 304 stainless steel is a widely used material for manufacture of machinery parts in different industries such as food, construction, automotive, naval and mining. Many of the failures of these components are related to fatigue and, in order to adhere to the principles of the Circular Economy, repair is proposed over replacement with a new component. As remanufacturing of mechanical components is a growing trend, it is of utmost importance to generate information about mechanical properties of repaired metallic components. Welding and material deposition processes remain the direct option for repairing damaged metallic components. In this work, a process of welding repair was simulated on a sample of AISI 304 stainless steel to evaluate its effect on fatigue strength. AISI 304 specimens were designed to obtain a high first natural frequency to accelerate the tests. To simulate damage, 1.5 mm deep grooves were made in the flat AISI 304 specimens by conventional milling. The repair process involved filling the grooves with ER 308L steel wire using the gas tungsten arc welding (GTAW) technique. Three orientations of reparation were chosen to evaluate the influence of the direction of principal stress in the endurance of the repaired AISI 304 component. To evaluate fatigue strength of a repaired component, a vibration-based fatigue test was conducted using an electrodynamic shaker. At the end of the fatigue tests, fractured specimens were analyzed using scanning electron microscopy. The results indicate that it is possible to recover up to 78.72% of the useful life of a damaged AISI 304 component repaired by welding, depending on the orientation of the repair relative to the direction of the principal stress. A progressive reduction in endurance was found as the orientation of the repair process varied relative to the principal stress direction.

description: In recent years, the implementation of immersive technologies such as Virtual Reality (VR) and Augmented Reality (AR) for Industry 4.0 (I4.0) applications has increased considerably. These technologies enable the connection of virtual and real environments focusing on human centered manufacturing. A challenge when implementing immersive technologies in industrial tasks is the lack of clear paths to select the most appropriate technology for specific operations, and the nonexistence of metrics to evaluate the integration performance. Nonetheless, there are trends in the literature that offer insights to conduct the decision making process for selection between immersive technologies, ensuring the suitability of the application. Based on the decision criteria identified in the literature a decision making approach is developed. This thesis also presents the development workflow of three VR/AR applications implemented in Unity Engine for Meta Quest 3 and Hololens 2. These applications are evaluated using overall performance metrics and are analyzed using the proposed approach.

description: For the use of the CSS model, workflows are needed to describe, assign and derive capabilities. This contribution provides a Capability Determining method that encompasses the three underlying technology-independent methods to guide stakeholders in describing, assigning and deriving capabilities for manufacturing. The first underlying method, Describing Capabilities, describes a workflow for the formal semantic description of capabilities. The workflow for assigning capabilities to a production resource is explained using the second method Assigning Capability. In the last workflow, capabilities are derived from a production specification or a process description using the method Deriving Capability.

description: Gravitational waves (GW) predicted by General Relativity, can be easily detected at LIGO VIRGO-KAGRA (LVK) observatories when very energetic astronomical events occur, such as the collision of two massive compact objects and more recently; Core-Collapse Supernovae (CCSNe). Even though this kind of GWs have not been detected yet, there are a lot of works dedicated to run numerical simulations to get a waveform that resembles those that can be observed in the next years. Besides the problem of detection, it is very interesting to know how to estimate physical parameters from the sources that arise a specific waveform. In this thesis work, the parameter estimation task is performed using the Markov Chain Monte Carlo (MC-MC) method using two different types of signals for the core-bounce stage of CCSNe: analytical signals generated by a model proposed in previous works and 2D numerically sim ulated waveforms. As a first case, gaussian white noise is injected to analytical signals to test MC-MC performance, then a second case deals with analytical signals in LIGO colored noise, and a last case considers LIGO colored noise injected in 2D numerically simulated signals. Results show the performance of MC-MC in each particular kind of signal and noise, having better results in the analytical signals embedded in gaussian white noise. Nevertheless, the last case shown better results for the estimated parameters than other techniques such as the ones used in related works. Additionally, a brief discussion about MC-MC computational time and implementation details are discussed

description: Die richtige Information zur richtigen Zeit am richtigen Ort – dieser Leitgedanke erhält im Rahmen der Industrie 5.0 eine zunehmende Bedeutung, insbesondere für den grundlegenden Wert der Menschzentrierung. Komplexe industrielle Anlagen, wie die in diesem Beitrag behandelte Wärmepumpenanlage, enthalten zahlreiche und vielfältige technische Informationen. Ein Instandhaltungstechniker, der auf Alarmsignale reagiert und ortsbezogene Maßnahmen innerhalb einer Anlage ergreifen muss, steht vor der Herausforderung in diesem komplexen Umfeld zielgerichtet an nötige Informationen zu gelangen, um anfallende Kosten zu minimieren. Standortbezogene Dienste (LBS) bieten hierfür potenzielle Lösungen, allerdings ist die Anwendung dieser im industriellen Bereich defizitär, da bestehende Systeme und Forschungsarbeiten sich vorwiegend auf Verbraucheranwendungen fokussieren. Dieser Beitrag legt den Schwerpunkt auf die industrielle Anwendungslösung mittels LBSs. Hierzu wird am Beispiel einer komplexen Wärmepumpenanlage das Konzept eines räumlichen Informationsmodells (SIM-CIP) für industrielle LBSs verdeutlicht. SIM-CIP integriert räumliche Informationen mit attributiven Informationen und geht zusätzlich über die rein ortsbezogene Erweiterung hinaus. So werden mögliche kontextabhängige Faktoren, die einen industriellen Arbeiter betreffen, berücksichtigt. Das konzeptionelle Modell umfasst fünf grundlegende Systeme – ein Datenbanksystem, ein Kartierungssystem, ein Positionierungssystem, ein Kontextmanagementsystem und eine Benutzerschnittstelle – die im Rahmen dieses Beitrages näher erläutert werden.

description: As the global population continues to grow, there is an increasing need to enhance the efficiency of production processes. On one hand, manufacturing processes face numerous challenges; on the other hand, various machines in the production line require an initial warm-up phase, which intersects with the fields of operations research and optimization. This dissertation explores the introduction of several concepts along with the warm-up process into the manufacturing workflow. It also addresses a range of issues associated with the warm-up in manufacturing, proposing solutions to these challenges. It tackles common problems in the production line, such as shortages, the environmental impact of carbon emissions, and the production of faulty items. The work at hand employs a diverse set of approaches, from mathematical solutions like the application of the Hessian matrix to the implementation of Karush-Kuhn-Tucker conditions. A variety of methodologies have been applied, ranging from analytical approaches to metaheuristics and innovative deep reinforcement learning techniques. The outcomes of this thesis have resulted in three published papers, with two additional works finished. The publications explore the effect of warm-up process in sustainable EPQ model, the effect of machine downtime on warm-up process, presence of shortage and faulty products with warm-up, machine downtime effect along with shortage on warm-up, and finally multi-product lot scheduling problem with warm-up process. The findings can be regarded as determination of optimal total cost for the system which provides higher revenue for corporations. In case of three published papers, this is done due to analytical approach and mathematical framework, in other words, a closed-form solution represents the whole structure. The solution methodology highlights key concepts, such as shortages and environmental regulations, by comparing results that show how the additional cost of carbon policies and the system’s ability to handle shortages contribute to lower overall costs. In cases involving rework and scrap, rework is shown to incur less cost. Finally, the multi-agent reinforcement learning effectively tackled the stochastic nature of metaheuristic algorithms in fine-tuning the control parameters. Altogether, each paper presents a specific direction within this thesis, and collectively, these provide practical insights for decision-makers in the industry.

description: Während der Entwicklung von automatisierten Anlagen ist die Spezifikation der Steuerungslogik ein wichtiger Schritt. Um diesen Prozess mit formalen Methoden zu unterstützen, kann die Steuerungslogik zunächst mithilfe eines formalen Modells spezifiziert werden, was eine formale Verifikation ermöglicht. In einem Vorgängerbeitrag der Autoren wurde eine solche Verifikation vorgestellt, die es ermöglicht, GRAFCET-Spezifikationen zu analysieren. In diesem Beitrag wird dieses Konzept um die Modellierung von Streckeninformationen erweitert. Die Modellierung von Streckeninformationen ermöglicht eine genauere Verifikation und in Teilen eine Reduktion des Zustandsraums. Anhand eines durchgängigen Beispiels werden zwei Ansätze für die Modellierung von Streckeninformationen vorgestellt und verglichen: die Modellierung mittels Invarianten und die Modellierung mittels GRAFCET. Bei der Modellierung mittels GRAFCET wird gezeigt, wie neben dem Verhalten der Steuerstrecke auch zusätzliche Eigenschaften des kombinierten Verhaltens modelliert werden können, wie beispielsweise die korrekte Abarbeitung des SPS-Zyklus. Um diese zusätzlichen Eigenschaften anwenderfreundlich modellieren zu können, wird eine Erweiterung von GRAFCET vorgestellt und gezeigt, wie dieses Konzept zur Modellierung von Streckeninformationen in die bereits vorgestellte Werkzeugkette zur Verifikation von GRAFCET-Spezifikationen integriert werden kann.

description: This master thesis proposes a detailed strategy that includes a mathematical model that de scribes the dynamics of an asymmetric 5-level flying capacitor inverter, as well as a model based control scheme and a novel model-based modulation technique. The presented study introduces a novel model-based control scheme based on the struc ture of a proportional-resonant controller, paired with a phase-shifted PWM modulation to drive the topology. Simulation models in Matlab/Simulink are conducted to prove through numerical evaluation that the inverter and its control scheme yield good dynamical perfor mance. The numerical results prove that the proposed control scheme achieves excellent dynam ical performance in terms of response time, even under system perturbations. The presented control technique delivers rapid correction actions and delivers an overall stable response with little Total Harmonic Distortion (THD) on the injected current. Additionally, this thesis presents an empirical control scheme to pre-charge the flying capacitor during system startup. This significantly reduces the transient inrush peak current, as well as minimizes the flying capacitor voltage overshoot. Overall, the results demonstrate that the combination of a model-based PR controller paired with a model-based adaptation of a PS-PWM modulation scheme is adequate to drive a 5-level flying capacitor inverter. Finally, the presented control and modulation schemes open avenues for further develop ment and scalability into higher-level flying capacitor inverters, as well as a possible practical deployment of the presented algorithms

description: Sowohl die passive als auch die reaktive Verwaltungsschale (VWS) halten immer mehr Einzug in die Praxis. Ebenso wird der Einsatz und die Entwicklung proaktiver VWS, deren Umsetzung zum aktuellen Zeitpunkt noch nicht spezifiziert ist, in aktuellen Forschungsprojekten evaluiert. Das Ziel ist, einen Überblick über die derzeit bestehenden Möglichkeiten für die Implementierung einer proaktiven VWS zu geben und somit einen Teil zu deren Spezifizierung beizutragen. Die drei Schwerpunkte liegen dabei auf der Realisierung der Architektur und Schnittstelle, sowie auf der flexiblen Integration verschiedener Interaktionsmuster für proaktive VWS.

El objetivo central de la Escuela Radiofónica Atarraya de Saberes, es visibilizar aspectos culturales e históricos como: mitos, cuentos, leyendas, historia, iniciativas colectivas, entre otros,de los municipios de Riosucio y Bojayà Chocó. Relacionando los procesos de creación de capacidades políticas territoriales con la recuperaciónde las tradiciones, la historia y lo autóctono propio de las comunidades. Es decir la Escuela Radiofónica permite la circulación de los saberes ancestrales y propios de la comunidades, como una forma de memoria histórica, pero también, de construcción de liderazgo político.

El Laboratorio Vivo, Veni ve la Minga de la Atarraya, surge como un escenario colaborativo que potencia la inteligencia colectiva diseñado como estrategia de participación y creación que apoya la Escuela Itinerante Atarraya de Saberes, permitiendo pensar en las distintas formas de organización para recuperar distintossaberes, historias y tradiciones culturales y conectarse con las personas de las comunidades para potenciar el aprendizaje en las nuevas generaciones.
