Pujol Vázquez, Gisela (Date of defense: 2004-11-19)
En aquesta tesi, presentem una solució per a dos problemes rellevants en la teoria de control: el problema del cost quadràtic garantit i el problema del control H∞, per a un cert tipus de sistemes. Considerem els ...
Ozón Górriz, Javier (Date of defense: 2001-07-23)
En la presente tesis se analiza el problema del coloreado de grafos tanto desde el punto de vista teórico como en relación a la resolución del problema mediante técnicas algorítmicas, algunas de las cuales se describen por ...
Montserrat Adell, Jordi (Date of defense: 2018-07-20)
Decision-making is an active field of research. Specifically, in recent times, a lot of contributions have been presented on decision-making under linguistic assessments. To tackle this kind of processes, hesitant fuzzy ...
Agis Cherta, David (Date of defense: 2020-12-21)
This thesis describes a structural health monitoring (SHM) strategy to detect and classify changes in structures that can be equipped with sensors. SHM is an area of great interest, because its main objective is to verify ...
Ponce de León Puig, Nubia Ilia (Date of defense: 2021-12-10)
This doctoral thesis exposes the development of a redesigned Predictive Control strategy that uses hysteresis to improve the performance of the controlled systems in different fields of application. The approach may use ...
Chrysokentis, Georgios (Date of defense: 2019-04-03)
This thesis develops a large eddy simulation framework for engineering applications using the finite element method. It focuses on the numerical formulation, the wall modelling approach as well as the generation of turbulent ...
Fanelli, Claudia (Date of defense: 2020-09-15)
Es conocido que muchas propiedades de las nanopartículas, como la luminiscencia, la fotoestabilidad, la eficiencia de la radiación óptica y las propiedades eléctricas, dependen del tamaño. Por lo tanto, la capacidad de ...
Monsó Burgués, Enrique P.J. (Date of defense: 2022-10-20)
(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 ...
Deutschmann, Ina Maria (Date of defense: 2021-11-29)
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 ...
García-Blanco, Raquel (Date of defense: 2017-02-09)
The Power Flow model is extensively used to predict the behavior of electric grids and results in solving a nonlinear algebraic system of equations. Modeling the grid is essential for design optimization and control. Both ...
Rodríguez del Río, Óscar (Date of defense: 2021-07-06)
The main objective of this dissertation is the study of the ejection-collision (EC) orbits in the circular and planar Restricted Three Body Problem (RTBP from now on). In particular, we will focus on the analytical and ...
