This doctoral thesis presents the use of an opto-electronic system so-called OBR (Optical Backscattered Reflectometer) as an alternative of measurement in structural health monitoring (SHM) processes in concrete structures, ...
El objetivo de esta investigación fue obtener un modelo matemático de calibración que permita estimar cuantitativamente el patrón ventilatorio (PV), en términos de volumen, en un grupo de voluntarios sanos y pacientes con ...
La tesis "Monitorización del progreso en el aprendizaje" se desarrolla en el contexto de la educación y las tecnologías de la información y la comunicación. Si podemos aprovechar los beneficios que ofrecen las TIC para ...
En un contexto de I+D+i (investigación + desarrollo + innovación), diversos estudios apuntan a la existencia de una fuerte relación entre comunicación y resultados, mostrando que la colaboración y compartición de conocimiento ...
When humans observe a scene, they are able to perfectly distinguish the different parts composing it. Moreover, humans can easily reconstruct the spatial position of these parts and conceive a consistent structure. The ...
The Simultaneous Localization and Mapping (SLAM) problem is widely acknowledged as one of the fundamental problem to solve in perception and robotics to produce actual mobile robotic agents. The problem itself is that of ...
The goal of the thesis is the effective computation of the geometric monodromy, equivalently the monodromy in the fundamental group, for families of compact connected Riemann surfaces (complex algebraic curves) of genus ...
The main object of study of this thesis is the development of artificial diffusion shock capturing techniques for continuous and discontinuous Galerkin (cG and dG) approximations of the convection-diffusion problem. Special ...
This thesis covers the development of monotonicity preserving finite element methods for hyperbolic problems. In particular, scalar convection-diffusion and Euler equations are used as model problems for the discussion in ...
Two innovative radiotherapy (RT) approaches are under development at the ID17 Biomedical Beamline of the European Synchrotron Radiation Facility (ESRF): microbeam radiation therapy (MRT) and minibeam radiation therapy ...
The main objective of the thesis is to study static and/or dynamic properties of a set of quantum fluids by means of quantum Monte Carlo techniques, mainly using the path integral formalism to obtain results both at zero ...
Since white dwarfs are the final stage of the evolution of the vast majority of stars, they carry important information about the chemical evolution of our Galaxy, its star formation rate, and its structure and dynamics. ...
The Thesis is devoted to simulations of quantum phase transitions by means of Quantum Monte Carlo techniques. Quantum phase transition is a transition between phases at zero or low enough temperature, where quantum effects ...
The city morphology is the greater evidence of human habitation and intervention on the natural landscape aimed both at individual protection and community living. It is an intervention that modifies not only the landscape ...
Esta tesis investiga sobre el proceso de transformación de la forma arquitectónica, analizando una técnica específica denominada morphing. La técnica del morphing se utiliza en los gráficos por ordenador para la transformación ...
While marine, anthropogenic noise pollution is a scientific and societal matter of concern, there is limited knowledge on how sea animals, particularly cetaceans, perceive their environment through sounds. Toothed whales, ...
En esta tesis se estudia la formación y mantenimiento de los bancos de arena sobre la plataforma continental asociados a la costa. Estos son estructuras sedimentarias de forma alargada y que se repiten periódicamente a lo ...
The natural fibers that come from vegetable origin have become a potential and competitive option as a reinforcement composite based on cement. This is due to their high resistance and low cost features, and also their ...
Although silicon (Si) is used in most current commercial power semiconductor components, Si capabilities are insufficient for new energy conversion requirements. Some of its important limitations are related with power ...
Motion planning is a traditional field in robotics, but new problems are nevertheless incessantly appearing, due to continuous advances in the robot developments. In order to solve these new problems, as well as to improve ...
