Influence of axial compression ratio in building columns
(English) Axial forces in columns of moment-resisting frames (MRF) have a paramount role for the seismic performance of these structural systems. Nonetheless, there are significant gaps in the literature entailing the ...
Process understanding of induced seismicity during stimulation of enhanced geothermal systems
(English) This doctoral thesis investigates the causes that induce (micro)seismicity as a result of hydraulic stimulation in fractured low-permeability rock. Understanding such phenomenon is of paramount importance to ...
Assessment and characterization of subsidence in the Catalan potash basin
(English) The importance of potash is inevitable to life on the planet earth as it is required by living mechanisms including plants, animals and human beings. In Europe, this vital ore is produced mainly by Germany and ...
Comunicación corporativa y su influencia en la generación de capital social empresarial
(English) Organisations use communication in the process of managing their commercial, institutional or social responsibility activities to form and maintain relationships with different audiences. Beyond being a way to ...
MIPing complex multi-action management planning: models, algorithms, and variants
(English) We are living in an era where the complexity of environmental challenges is unprecedented. Biodiversity loss, habitat degradation, and climate change are interconnected issues requiring a comprehensive and ...
A double full-stack architecture for multi-core quantum computers
(English) Despite its tremendous potential, it is still unclear how quantum computing will scale to satisfy the requirements of its most powerful applications. Continued progress in the fabrication and control of qubits ...
Las transiciones agroecológicas justas en los sistemas agroalimentarios: analizando el género y los conocimientos tradicionales
(English) This doctoral research develops the issue of just agroecological transitions in the food system and develops two case studies in the Global North and Global South. Based on the framework developed to analyze ...
Clustering large dimensional data via second order statistics: applications in wireless communications
(English) In many modern signal processing applications, traditional machine learning and pattern recognition methods heavily rely on the having a sufficiently large amount of data samples to correctly estimate the underlying ...
Simulation of two-fluid immiscible Stokes flows using hybrid nonconforming methods and geometrically unfitted meshes
(English) We consider two-fluid problems involving immiscible Stokes fluids in contact and with surface tension at their interface. We develop, analyze, and compare two approaches for space discretization, the Hybrid ...
Vibrations and energy transfer in molecules enhanced by single nanoantennas
(English) Light is a powerful non invasive tool for probing matter down to its fundamental molecular properties. The past three decades saw advent of metallic nanoantennas engineered to concentrate light into sub diffraction ...
Impacte ambiental de la valorització d’un residu industrial aviari per a l’obtenció de materials compòsits
(English) Chicken meat production has increased in recent years and is expected to continue growing, which also increases the generation of waste from the poultry industry. Chicken feathers (PlP) are one of these wastes ...
Evaluation of nutrient recovery from urban wastewater for sustainable fertilizer production
(English) The 20th-century introduction of the Haber-Bosch nitrogen fixation process significantly disrupted the nitrogen cycle in ecosystems, contributing to environmental issues and nutrient loss. The heavy reliance on ...
Promoting cardiac regeneration by biomimetic microenvironments
(English) Cardiovascular diseases are the most common cause of death in the world. The heart has a very limited regeneration capacity. Thus, following tissue damage – e.g., myocardial infarction –, heart transplantation ...
Caracterització multiescala de dades fisiològiques en la cardiologia translacional
(English) This thesis aims to explore cardiac cell physiology across various scales, also known as translational cardiology. The research employs novel computational techniques from Biomedical engineering and utilizes ...
Investigación en nuevas técnicas de microencapsulación biodegradables de fragancias para el sector de detergencia que eviten la liberación de microplásticos al medio ambiente
(English) Getting to give added value in the different products that are nowadays in the market has not been easy. Since many years ago we have worked on the addition of fragrances in different articles. This added value ...
Revolutionizing space mission event modeling with the Tychonis framework
(English) This thesis presents the Tychonis framework, a solution to the limitations faced by existing software packages used in space missions to identify geometric events. The framework is designed to integrate with ...
DA&AI supporting tools for gas turbine’s efficiency improvement: maintenance, operation modes and performance enhancement
(English) Digitalization has revolutionized many industries, including the power generation sector. The availability of a vast amount of data from various systems has transformed decision-making processes in Industry. ...
Relación entre estratificación socioeconómica y exposición al material particulado (PM10 y PM2.5) en el área urbana de Botogá (Colombia)
(English) Environmental inequality metrics require complex analyses between social, economic and environmental variables at different scales. The current research develops metrics within this framework to determine ...
Sistema de evaluación y priorización de inversiones públicas
(English) This doctoral thesis addresses one of the most significant challenges facing the Spanish administration: the efficient selection and management of public investments. To achieve this goal, the 'Public Investment ...
Fractal approach to wheel-rail roughness contact theory
(English) In this study, the Weierstrass fractal function was used to model the surface roughness of railway tracks and, subsequently, the static coefficient of friction (COF) for Hertzian rail-wheel contact and cylinder-plane ...
