Ecologías [des]tejidas : un discurso sobre la 'relación'
(English) This research addresses the theme of coexistence, a concept of increasing relevance in the current context, marked by the economic, social, and environmental crises that have been manifesting globally since the ...
Análisis y propuesta de calificación sísmica de elementos no estructurales
(English) In the nuclear industry, safety-related equipment and components must be designed to withstand earthquakes without losing functionality. The floor response spectrum (FRS) is a widely used method for seismic ...
Dry-electropolishing of WC-Co cemented carbides: chemical, microstructural and mechanical characterization
(English) WC-Co cemented carbides are widely used in industry, particularly for cutting tools, due to its exceptional combination of mechanical properties. They are composites consisting of tungsten carbide (WC) particles ...
Ground-based GEOSAR system using DVB-S/S2 signals of opportunity and FPGA based correlators
(English) The SAR satellite missions from Geostationary Orbits (GEOSAR) offer short revisit times of less than 24 hours, which are essential for monitoring fast-evolving phenomena. A first mission has recently been launched ...
Collocation methods for the synthesis of graceful robot motions
(English) Graceful motion can be loosely defined as the one we observe in natural movements executed by animals and humans, which are characterized by being agile, efficient, and fluid. The generation of graceful robot ...
Unobtrusive ultra-short-term HRV analysis for the identification of physiological states in healthy people
(English) In recent years, heart rate variability (HRV) has become an essential tool for assessing the function of the autonomic nervous system (ANS), reflecting the balance between the sympathetic (SNS) and parasympathetic ...
Integrating modeling, synthesis, and knowledge management to support strategic decision-making toward the circular economy paradigm
(English) This thesis tackles some of the most urgent global issues we face today: waste accumulation, resource scarcity, and climate change. The focus is on applying sustainable practices through models like Industrial ...
Morphodynamic modelling for coastal hazard mitigation
(English) Mediterranean sandy beaches are facing increasing hazard, a situation that will be exacerbated due to climate change. This thesis focuses on the analysis of flooding and erosion along Catalan beaches under present ...
La reconversión de los espacios portuarios, en el Puerto de Balboa en el Pacífico de Panamá. Propuesta de mejora de la operativa mediante un modelo de optimización
(English) The coexistence of ports in the Panamanian Pacific with their surroundings requires everyone to have access to the ability to move around in an organized and spontaneous manner. The Port of Balboa, one of the ...
New approaches for resource management and job scheduling for HEP grid computing
(English) The Large Hadron Collider (LHC) ALICE (A Large Ion Collider Experiment) experiment uses grid computing for its extensive data processing and analysis. The ALICE Grid is composed of 48 sites distributed globally, ...
Fault diagnosis and prognosis approach using data-driven structurally generated residuals
(English) In this thesis, we will propose methods to combine structural analysis methods and data-driven techniques, extending the applicability of conventional model-based diagnosis methods and proposing an extension to ...
Contextualization of spatio-temporal action localization systems and media content applications
(English) Spatio-temporal action localization is a field of computer vision that determines both the spatial and temporal locations of actions taking place within a video. This particular task is one of the cornerstones ...
Architecture-aware sparse patterns to accelerate inverse preconditioning
(English) This work focuses on improving the efficiency of iterative methods for solving large and sparse linear systems. These problems arise in many fields, including climate modeling, molecular and fluid dynamics, among ...
