Sustainability, durability and mechanical characterization of a new recycled textile-reinforced strain-hardening cementitious composite for building applications
Cementitious materials have one of the highest compressive strength-to-weight ratios compared to other construction materials. Nonetheless, both tensile strength capacity and toughness result to be an order of magnitude ...
Vessel Traffic Services, towards e-Navigation : the role of Oceanic VTS in global maritime surveillance
This thesis presents the study and analysis of the Vessel Traffic Services (VTS), from its origins to the present, with further evaluation of future trends. Examining the current trend in terms of technologies that are ...
A socio-technical approach for assistants in human-robot collaboration in industry 4.0
The introduction of technologies disruptive of Industry 4.0 in the workplace integrated through human cyber-physical systems causes operators to face new challenges. These are reflected in the increased demands presented ...
Textile UHF-RFID antenna sensors based on material features, interfaces and application scenarios
Radio frequency identification over measurable ultra-high frequency textile substrates (UHF-RFID) is a promising technology to develop new applications in the field of health and the Internet of Things (IOT), due to the ...
Resilience for large ensemble computations
With the increasing power of supercomputers, ever more detailed models of physical systems can be simulated, and ever larger problem sizes can be considered for any kind of numerical system. During the last twenty years ...
Metapostales: la imagen moderna de España a través de las tarjetas postales en el boom desarrollista
In the introduction to the first chapter of her book On Photography, specifically in the well-known text on the fragment of the film Les Carabiniers (1963) by Jean-Luc Godard, Susan Sontag refers to postcards with a certain ...
Optimal operation and design of modular multilevel converter for HVDC applications
Modular Multilevel Converters (MMCs) are a type of Voltage Source Converter (VSC) which have become the preferred topology choice for High Voltage Direct Current (HVDC) applications. Compare to its HVDC converter predecessors, ...
Model order reduction methods for sensor data assimilation to support the monitoring of embankment dams
The latest monitoring and asset management technologies for large infrastructures involve digital representations that integrate information and physical models, exist in parallel to the real-life structures, and are ...
Data and methods for a visual understanding of sign languages
Signed languages are complete and natural languages used as the first or preferred mode of communication by millions of people worldwide. However, they, unfortunately, continue to be marginalized languages. Designing, ...
Local preconditioning for parallel iterative solvers
This thesis aims at improving the convergence of iterative solvers, used for algebraic systems coming from the discretization of partial differential equations (PDE), in the context of large scale simulations and high ...
Domos desplegables : método geométrico a partir de polígonos regulares
This research proposes a design method for deployable domes from the scissor-type system, starting from the geometry of regular polygons for its configuration. The geometry of the regular polygons inscribed in a circumference, ...
Development of CFD-based multi-fidelity surrogate models for indoor environmental applications
This thesis presents a methodology for CFD-based multi-fidelity surrogate models for indoor environmental applications. The main idea of this work is to develop a model that has accuracy comparable to CFD simulations but ...
Comparison of the mesophilic, thermophilic and temperature-phased anaerobic digestion of sewage sludge
Anaerobic digestion (AD) is currently spread all over the world for sewage sludge stabilisation, volume reduction and green energy production. Its implementation contributes to turn a wastewater treatment plant (WWTP) into ...
The management of fire complexity at the edge of criticality
Fire regimes are changing under the influence of global change. On the European continent, landscape memory in the 21st century is dominated by an accumulation of forest fuel and irrupted by a progressive climatic forcing ...
Diferent approaches to improve groundwater resources management : submarine groundwater discharge and managed aquifer recharge
Global change is expected to affect significantly the global hydrological behavior, changing mean annual precipitation patterns, increasing length of drought periods, rising evaporation and atmospheric water vapor and ...
Inspección no destructiva de estructuras mediante georradar : análisis de daños por corrosión y por otras patologías
This thesis aims to studythe capacities and limitations of Ground Penetrating Radar (GPR) to support inspection, assessment, maintenance and rehabilitation tasks, helping to earlydetection and evaluation ofpathologies in ...
Study and application of spectral monitoring techniques for optical network optimization
One of the possible ways to address the constantly increasing amount of heterogeneous and variable internet traffic is the evolution of the current optical networks towards a more flexible, open, and disaggregated paradigm. ...
Disentangling ecological networks in marine microbes
There is a myriad of microorganisms on Earth contributing to global biogeochemical cycles, and their interactions are considered pivotal for ecosystem function. Previous studies have already determined relationships between ...
Assessment of the societal impact of research and innovation in the agri-food sector
Research value, research relevance, research quality, and research impact have been widely tackled by various disciplines, such as health, engineering, management, and sustainability. How research and innovation are being ...
Development of cognitive workload models to detect driving impairment
Driving a vehicle is a complex activity exposed to continuous changes such as speed limits and vehicular traffic. Drivers require a high degree of concentration when performing this activity, increasing the amount of mental ...
