Transparent surfaces based on ultrathin materials with tailored optical and biological functionalities
(English) The properties of ultrathin materials present exciting opportunities to develop multifunctional surfaces. In addition, the use of plastic and thin glass as transparent substrates has the potential to extend the ...
Nonlinear optics with a Rydberg ensemble for quantum information processing purposes
(English) Photons have emerged as the main candidates for carrying quantum information due to their weak interaction with the environment. Unfortunately, their limited interaction with one another poses challenges for ...
A data-driven approach to prescribe web API evolution
(English) In the last two decades, the use of web Application Programming Interfaces (APIs) has grown exponentially, providing both consumers (software developers) and providers (companies and institutions that expose their ...
Novel transversal topologies and coupled resonator configurations for acoustic wave filters
(English) During the last years, electro-acoustic technology has been a key factor in the development of portable devices thanks to its high performance and very compact filtering structures. Such a technology has enabled ...
Return of the marine heterotrophic flagellates: diversity, distribution and gene expression patterns
(English) Marine heterotrophic flagellates (HF) are very small (2-5 µm) unpigmented protists that are dominant bacterial grazers in the ocean, where they link the transfer of carbon from bacterial cells to higher trophic ...
Incorporación de la valoración de los servicios ecosistémicos en las políticas de sostenibilidad de entornos urbano-regionales: Medellín, Valle de Aburrá y la región central de Antioquia
(English) This paper explores the interdependent relationship of cities, as an expression of the process of urbanization and human agglomeration, as well as of all their spatial, political, social, economic and environmental ...
Multi-agent graph learning-based optimization and its applications to computer networks
(English) In the wake of a digital revolution, contemporary society finds itself entrenched in an era where network applications' demands surpass the capabilities of conventional network management solutions. This dissertation ...
Smart and efficient sensor networks operation for 5G and beyond ecosystems
(English) Sensor Networks (SN) will play an integral role in Beyond 5G (B5G) ecosystems, especially for highly-distributed use cases and services such as Digital Twins (DT). Thus, the underlying transport network needs to ...
Design optimization of dual active bridge converter
(English) The proliferation of batteries for local storage and electric vehicles (EVs) is rising steadily. The EV market’s prospects point to exponential growth in the coming years. This trend has also contributed to the ...
Preparation and characterisation of bimetallic catalysts for the steam reforming of methane
(English) Heterogeneous catalysis is one of the most important chemical technologies available today to produce most chemicals at the basis of industrial production. The transition to a greener energy production demands ...
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 ...
Understanding and mitigating the post-injection seismicity induced by fluid injection in enhanced geothermal systems
(English) Induced seismicity due to hydraulic stimulation and circulation is a hurdle for the development of Enhanced Geothermal Systems (EGS). The monitored seismicity has occasionally reached magnitudes large enough 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 ...
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 ...
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 ...
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 ...
