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 ...
Meibomian gland dysfunction and dry eye symptoms of fitted and over the counter contact lens wearers compared with non-contact lens wearing controls
(English) Meibomian gland dysfunction (MGD) is a chronic and diffuse abnormality of the meibomian glands (MGs) that occurs in 38% of contact lens (CL) wearers, though the influence of CLs on MGD is equivocal. A topical ...
Diseño de sistemas de electrificación autónomos para comunidades rurales considerando incertidumbre en la estimación de la demanda
(English) The United Nations objective to ensure energy access for all is still far from being achieved, particularly in rural areas of developing countries. In order to expand access to electricity, isolated systems, ...
Mathematical and computational modeling of active cellular flows
(English) During development, cellular tissues undergo dramatic reconfigurations as a result of organized flows driven by active forces. Depending on the system, cellular flows and active forces can be understood from a ...
Study of hybrid FRP-FRCM superficial structural elements
(English) The most common composite materials for strengthening building structures are divided into two dif ferent types based on the matrix’s composition, organics (polymers) or inorganics (cement, lime). The hybrid ...
Single-atom motional dynamics in an optical dipole trap
(English) This thesis studies, using simulation and experiment, the motional dynamics of a single atom in an optical dipole trap. The optical dipole trap we study is a single-beam, red-detuned, far-off-resonance trap (FORT). ...
Mechanics of epithelial tissue subjected to controlled pressure
(English) Epithelial sheets form specialized 3D structures suited to their physiological roles, such as branched alveoli in the lungs, tubes in the kidney, and villi in the intestine. To generate and maintain these structures, ...
Development of quenching and partitioning steels (Q&P)
(English) The automotive industry is constantly seeking to improve the performance of the car and at the same time reduce CO2 emissions into the environment, which can be achieved among other solutions through the use of ...
Modelització energètica d’edificis a escala urbana a Andorra. Reducció dels desajustos dels models mitjançant dades de consum d'energia desagregades
(English) The building sector has nowadays become a key point for policies and strategies to reduce energy and greenhouse gas emissions. The significant and unprecedented urban expansion that occurred in recent years and ...
Causal discovery and prediction: methods and algorithms
(English) This thesis focuses on the discovery of causal relations and on the prediction of causal effects. Regarding causal discovery, this thesis introduces a novel and generic method to learn causal graphs by performing ...
L'Antoni M. Gallissà i Soqué, arquitecte (1861/1885/1903). Biografia, analisi de l'obra i recuperació gràfica
(Català) A partir d'un material gràfic, fotografies i dibuixos s'ha fet la biografia d'un arquitecte fins ara molt desconegut i que va jugar un paper que considerem de molta importància dintre del Modernisme. Deixeble de ...
Soil-structure interaction in the performance-based seismic design of reinforced-concrete buildings
(English) When analyzing structures for seismic design and performance assessment purposes, it has been common to assume that the ground motions or their equivalent representations correspond to that of the free-field ...
Remote sensing for atmospheric observation and wind energy: over-land boundary layer and off-shore atmospheric stability
(English) Monitoring the atmospheric boundary layer (ABL) is a matter of interest for many applications, such as weather forecasting, pollutant-dispersion models and wind energy. The ABL is the most turbulent part of the ...
Construction and technological development of immersive virtual reality for pain therapy
(English) Virtual reality (VR) allows not only to easily change the perceived scenario but also to control several factors associated with the sense of being in an embodied virtual avatar that would not be achievable in ...
Contactos selectivos de portadores basados en óxidos metálicos de transición para células solares de kesterita
(English) In recent years, there has been an increasing need to find an environmentally friendly and low-pollution alternative for electricity production through solar energy absorption. Since 1950, photovoltaic researchers ...
