A novel arbitrary Lagrangian Eulerian framework for large strain solid dynamics
(English) In the realm of Computer-Aided Engineering applied to fast solid dynamics, the intricate mechanical behaviours exhibited by materials when subjected to strong dynamic forces, high speed impacts and complex ...
Optically detected nuclear magnetic resonance above and far below earth's magnetic field: spin dynamics and relaxation in unconventional regimes
(English) This thesis describes theoretical background, simulations, experimental apparatus and measurements of nuclear spin dynamics via optically pumped magnetometers in unconventional magnetic field regimes. It is divided ...
Development of textile capacitive sensor
(English) Nowadays, the textile clothing industry is searching for new ways to add value to their products. Developments in textile sensors start to demonstrate their usability and possibilities when they are integrated ...
Theoretical models for quantum simulators of novel materials and devices
(English) Over the past three decades, optically trapped ultra-cold atoms have served as a versatile platform for controlled exploration of numerous condensed matter phenomena. The successful fabrication of magic angle ...
Acontecimiento y ciudad. Cuando lo extraordinario transforma lo ordinario. Las fiestas de la Mercè y Barcelona
(English) The object of study of this investigation is centred on the potential that extraordinary events of the city have as a project design tool. We refer to instances in which the city is transformed into a laboratory ...
Speculation – postponement strategies in supply chain network design problems: a modelling framework for new supply chain strategies through stochastic optimization
(English) Speculation and Postponement are opposite supply chain strategies intended to either advance or postpone the necessary production processes to transform raw materials into finished goods. A Customer Order ...
Particle methods for reactive transport modeling in heterogeneous aquifers
(English) Aquifers are naturally heterogeneous systems across multiple scales, which poses a known difficulty for grid-based solvers of solute transport. When advection is the dominant transport mechanism, concentrations ...
Singularities and symmetries on the crossroads of geometry and physics
(English) In this thesis we study several mathematical objects that are essential to formulate and model physical systems. Applying the tools provided by differential geometry, we develop and analyze different mathematical ...
Hemp crop waste for green solutions in construction: physical and mechanical characterization
(English) The primary goal of this thesis is to unlock the potential of hemp stalk, an agricultural byproduct that currently lacks practical applications. The overarching aim is to promote the use of eco-friendly materials, ...
Multi-port container traffic analysis using Data Science tools: an application to Yangtze River Delta (China)
(English) As a crucial node of maritime transportation, seaports carry more than 90% of global trade. Considering the complexity of a port system, even slight improvement at strategical and operational decision levels will ...
Use of alternative materials in soil stabilization: mechanical and environmental aspects
(English) Currently, the two most raw material consumer industries are civil engineering and the pulp and paper industry. Meanwhile, these sectors face severe criticism due to their environmental impact. Additionally, by ...
On the use of decadal predictions for agricultural climate services: bridging the gap between service providers and users
(English) Unfavorable and extreme climate events such as drought and heat stress heavily impacts the agriculture sector and food security globally, and the impact of these climate hazards is expected to increase over 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 ...
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 ...
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 ...
