Plastic pollution in marine ecosystems: spatiotemporal assessment in beach sediments of protected coastal areas
(English) Plastic pollution has emerged as a critical threat to marine ecosystems, particularly in ecologically sensitive and protected coastal areas. This doctoral thesis presents a spatiotemporal assessment of plastic ...
Neural network-based data processing for satellite imagery in small satellite earth observation missions
(English) The increasing availability and miniaturization of satellite sensors have enabled CubeSats to emerge as powerful platforms for Earth Observation (EO). Despite their reduced size and low cost, CubeSats can provide ...
A multitemporal and multiscale analysis of soil erosion and sediment transport. Application to the badlands in the Upper Llobregat River Basin
(English) Badlands are among the most active geomorphic environments on Earth, exhibiting extreme erosion rates, sparse vegetation, and steep, deeply dissected slopes. In mountainous Mediterranean regions, seasonal climate ...
Functional safety for highly automated vehicles
(English) The rapid advancement of autonomous vehicle technologies offers significant opportunities to improve road safety, but also introduces challenges to ensure compliance with established safety standards. This thesis ...
Nanoparticle modeling in industrial settings
(English) Nanoparticles (NPs) are incidentally generated in the industry by multiple material transformation processes, especially by highly energetic activities. This type of aerosol, due to its small size, poses a ...
Relativity of time, circularity and recycled material quality in LCA for fast-moving products
(English) Life Cycle Assessment (LCA) is the preferred methodology for quantifying the environmental impact of systems along value chains. The LCA’s most important methodological feature is the use of the Functional Unit ...
Accelerating many-core, heterogeneous, and distributed architectures with hardware runtimes and programming models
(English) Due to increasing concern about energy efficiency and the current trend to scale out HPC systems to many computing nodes, this thesis tries to tackle both problems with the help of hardware acceleration and ...
Contributions to energy-efficient multi-radio architectures for novel IoT scenarios
(English) As wireless networks continue to evolve to support a growing variety of applications, energy efficiency has become a critical design requirement, particularly for devices operating on constrained power sources. ...
Towards a more sustainable B2C delivery in Barcelona: bridging consumer, parcel carrier, and municipal perspectives
(English) The rapid growth of e-commerce is worsening the negative effects of urban distribution on cities. Although the last-mile segment comprises only a small part of the supply chain, its impact is disproportionately ...
Applications of hydroxyapatite nanoparticles in the field of biomedicine
(English) In the biomedical field, calcium phosphates have attracted attention due to their biocompatibility and bioactivity. They can be found in different individual phases (e.g., amorphous calcium phosphate, tricalcium ...
A framework to operationalize and automate the data integration lifecycle
(English) Data plays a key role in today’s world. Many organizations collect and store massive amounts of data from many different data sources. As a result, these data collections show a diversity in structure and semantics ...
Post-quantum cryptography acceleration for next generation computers
(English) The security of modern cryptographic schemes relies upon mathematical problems that are assumed to be hard to solve, like the Rivest-Shamir-Adleman (RSA) problem or the discrete logarithm problem over elliptic ...
Numerical analysis of thermally-driven winds in mountain-valley regions
(English) This thesis aims at simulating thermally-driven winds in mountain-valley systems, using the open source computational fluid dynamics (CFD) software OpenFOAM. Thermal-driven winds occur in mountain-valley regions ...
Numerical modelling of unsaturated soils with the material point method
(English) The Material Point Method (MPM) is presented as an advanced numerical method used to simulate geotechnical problems subjected to large deformations and soil-structure interaction problems, such as landslides, ...
Surface impedance characterization of high-temperature superconducting coated conductors for potential application in the future circular collider beam screen
