Quantum adventures from analog to digital: gauge, scars and laughlin
(English) This is a thesis in theoretical physics about analog quantum simulations, digital quantum simulations (quantum computing), and quantum state preparation using different quantum platforms (neutral atoms, trapped ...
Biofertilizers and biostimulants from microalgae grown in wastewater: characterization and agronomic trials
(English) Chemical fertilizers have played a crucial role in modern agriculture, enabling high productivity rates to meet the demands of a rapidly growing global population. However, it is now evident that its overuse poses ...
Automatic control for unmanned ground vehicles
(English) This thesis explores advanced control strategies for trajectory tracking, state feedback, disturbance mitigation, and autonomous vehicle guidance across a range of dynamic systems. The research is divided into ...
Isla de frío de los parques urbanos: hacia la definición de parámetros de composición para la optimización del efecto de enfriamiento en distintos contextos climáticos mediante análisis remoto
(English) Due to their composition, generally characterized by the predominant presence of vegetation and permeable soils, urban parks exhibit lower temperatures compared to other areas of the city. In many cases, this ...
La volta de maó de pla tibada, element essencial de l'arquitectura de Domènech i Montaner
(English) Domènech i Montaner, a cultured architect and up-to-date with European developments, found in construction an ally to shape his architecture. In this, he did not stray too far from the dictates of Viollet-le-Duc: ...
Study on rock fragmentation mechanism and ball loading parameter matching in ball mill
(English) Abstract Rock fragmentation in ball mills is a key topic in rock mechanics with broad scientific and engineering significance. However, the understanding of the mechanical mechanisms and ball loading optimization ...
Surface modification treatments to enhance the performance of titanium backplate in keratoprosthesis
(English) The cornea is the outermost layer of the eye, essential for vision as it provides protection and contributes 80% of the eye’s refractive power. Its transparency and lack of blood vessels are key to its function, ...
Photon counting with a single neutral atom: quantum efficiency, dark counts, and background rejection
(English) This thesis studies the use of a single trapped neutral 87Rb atom as a photon counter. Detection of quantum jumps (QJs), i.e., abrupt changes between atomic states observable by a change in atomic fluorescence, ...
Development of a fuzzy logic-based algorithm for stroke detection in non-contrast computed tomography images
(English) The present work addresses the problem of early stroke detection, not only from the perspective of detection accuracy, but also focusing on computational efficiency, considering the limited availability of ...
Nanocavities and molecules: polaritons and their dynamic interactions
(English) This thesis investigates light-matter interactions within plasmonic nanocavities, using ultra- confined optical environments to observe and control molecular dynamics at the nanoscale. Plasmonic cavities, formed ...
Microfluidics for sweat monitoring
(English) This thesis began with the goal of revolutionizing continuous monitoring through the use of sweat. Over the course of this research, the field of sweat monitoring has evolved significantly, being consolidated as ...
Development of metal-enhanced TiO2-based photocatalysts for hydrogen production
(English) Human activity has led to rising greenhouse gas levels, altering climate patterns and intensifying weather events. Therefore, a transition to a decarbonized energy system is needed, with hydrogen as a promising ...
Data integration of longitudinal single-cell with multi-omics data to enable precision medicine for complex diseases
(English) Recent developments in high-throughput analysis technologies have transformed biomedical research by generating extensive longitudinal and heterogeneous multi-omics data, including transcriptomics, proteomics, ...
Graph-driven digital twins as assistants to bridge maintenance
(English) Bridges are vital components of transport infrastructure networks which are facing a widespread lack of resilience due to aging and changing environmental conditions. Finding more efficient methods for monitoring ...
Designing and development of secure protection strategies for distribution network integrated with distributed energy resources
(English) Global electricity generation increasingly incorporates Distributed Generation (DG) resources, such as solar and wind, into distribution systems (DS), offering benefits like improved reliability, power quality, ...
Thermo-hydro-mechanical-chemical impacts of high-temperature aquifer thermal energy storage
(English) High Temperature Aquifer Thermal Energy Storage (HT-ATES) involves the injection and extraction of non-isothermal fluids into aquifers and triggers thermo-hydro-mechanical-chemical processes. These processes must ...
Integration of spatial and temporal patterns for ecological environment management in river-riparian system
(English) Rivers are important carriers of water resources and important components of ecosystems. In some areas, rivers have been artificially narrowed, riparian areas have been encroached upon, riparian resources have ...
Control of a grid of multiple AC and DC sub-systems interconnected with power converters
(English) High Voltage Direct Current (HVDC) offers clear advantages for long distance electrical transmission. This is why its implementation is rising in the interconnection of remote renewable energy and interconnection ...
Mitigation of compound events in Barcelona: urban water scarcity, flood risk and reduction of surface temperatures through WSUD
(English) Climate change is bringing with it situations where droughts coexist with periods of extreme rainfall in many regions of the world. Surface temperatures are increasing due to more frequent drought periods. In ...
Multicriteria methodology for assessing the sustainability of last-mile electrification programs
(English) The sustainability-driven global energy transition requires ensuring universal access to electricity, particularly in last-mile rural areas. Renewable-based energy access programs are pivotal for fostering ...
