Leveraging graph neural networks for optimization and traffic compression in network digital twins
(English) In recent years, several industry sectors have adapted the Digital Twin (DT) paradigm to improve the performance of physical systems. This paradigm consists of leveraging computational methods to build high-fidelity ...
Structural performance of continuous composite bridges with partial shear connection and double composite action
(English) The steel-concrete composite structural solution has been widely applied in the execution of simply supported bridges since the merits of concrete compressive strength and steel tensile strength can be efficiently ...
Periferia y ciudad. El caso del Baix Llobregat en Barcelona
(English) The urban continuum of Barcelona extends through the Baix Llobregat, the mobility also forms an inseparable whole, the same happens with the economy, with social and cultural life; geography and the environment ...
Nonlinear optics at nanoscale: frequency conversion at interfaces
(English) The use of semiconductors, metals, or ordinary dielectrics in the process of fabrication of nanodevices is at the front edge of nowadays technology. In the last decade an impressive technological progress has ...
MASÍA URBANA: el papel arquitectónico y urbanístico de la masía en el área suburbana de Barcelona durante el siglo XX
(English) This thesis is based on a new concept of the ‘Urban Masia’ applied to the city of Barcelona between from the 1860s to the present. *(Although ‘‘masia’’ usually translated as 'farmhouse' in many cases, this term ...
Intelligent secondary control for energy management in a micro-grid by using multi-agent system
(English) Nowadays, distributed energy resources are widely used to supply demand in micro grids especially in green buildings. These resources are usually connected by using power electronic converters, which act as ...
Artificial intelligence, LiDAR and co-operative remote sensing for atmospheric observation and off-shore wind energy
(English) Remote sensing of the atmosphere is widely used by the wind energy industry to both assess future wind farms deployment sites as well as to improve their operation. With the rising interest in offshore wind energy, ...
Unstable motions in the three body problem
(English) The 3 Body Problem (3BP) models the motion of three bodies interacting via Newtonian gravitation. It is called restricted when one body has zero mass and the other two, the primaries, have strictly positive masses. ...
Theory and computation of multiscale epithelial mechanics : from active gels to vertex models
(English) Epithelial monolayers perform a variety of mechanical functions, which include maintaining a cohesive barrier or developing 3D shapes, while undergoing stretches over a wide range of magnitudes and loading rates. ...
Una nueva perspectiva del modelado y control de microrredes eléctricas y convertidores de potencia
(English) This doctoral thesis focuses on the modeling and control of electrical microgrids and triphasic converters. The starting points of this research work are based on previous work on modeling electrical microgrids ...
Discrete operators and distances on subdivision networks
(English) The research we have carried out lies within the domain of diffusion problems for elliptic operators that are defined on discrete structures called networks, that are graphs that are capable of discriminating ...
Experimental and numerical analysis of the unsaturated soil shrinkage and swelling behaviour under different compaction conditions
(English) The thesis presents part of an ongoing nvestigation on the Thermo-Hydro-Mechanical (THM) behaviour and cracking of deformable unsaturated soils undergoing cycles of drying and wetting. An experimental approach ...
Active flow control optimization on Selig Donovan 7003 airfoil
(English) The PhD focuses on the study of the flow around an airfoil at different Angles of Attack (AoA) with and without the implementation of Active Flow Control (AFC), while maintaining the Reynolds number constant at ...
La terre crue à l’épreuve des ambiances sonores : un dialogue entre la mesure physique et les expériences sensibles.
(English) Raw earth provides important environmental benefits, such as low embodied energy, lower greenhouse gas emissions, and infinite reversibility. Today, these already well-known benefits are boosting interest in ...
Flexoelectricity at surface instabilities and stress singularities
(English) The flexoelectric effect, the two-way linear coupling between strain gradient and electric polarization (direct flexoelectricity) or electric field gradient and strain (converse flexoelectricity) universally ...
Highly percolated ultra-thin metal films for reconfigurable metasurfaces
(English) There is currently significant scientific and technological interest in ultrathin materials, with at least one dimension in the nm range or even smaller, since they possess features not achievable with their ...
Determinación del grado de daño de una estructura mediante el análisis de la variación de frecuencias
(English) This thesis proposes to determine a damaged structure using the Principal Component Analysis (PCA) of modal frequency variation of sorne damaged and undamaged configurations. The estimators used are the accumulated ...
Specification, estimation and monitoring of quality-related software strategic indicators in agile software development
(English) In line with the current trend of exploiting corporative data, software companies, especially those using Agile and Rapid software development, are challenged to improve the quality of their products, their ...
Dynamic resource optimization and orchestration techniques for 5G new radio and beyond
(English) Earmarked as the revolutionary 5G key enabler, Network Slicing (NS) is the embodiment of the concept of running multiple logical networks as virtually independent business operations on a common physical ...
Effect of deformation on the mechanical behavior of an advanced steel of high resistance with high manganese content
(English) Pre-salt oil exploration means a new development path for Brazil. This activity stimulates investments from national and foreign companies, boosts the production of technology, promotes greater professional ...
