In the present thesis 3 detailed studies were carried out that spring from 3 different diagnostic techniques that include bronoscopy, tuberculine bacillus infection diagnosis, and the control of oxygen therapy in chronic ...
Estruch i Tena, Carles (Data de defensa: 2016-07-13)
We propose to develop, build and validate a new Concept of Bridge composed of Inflatable Beams, Lightweight, Modular and Portable (PVH-LMP) for surface transport vehicles, which uses pressurized air-filled beams made of ...
Rojas Hernández, Miguel Ángel (Data de defensa: 2019-11-20)
Nowadays, the growing demand for frequency-free bands for new emerging wireless technologies and fixed frequency allocation policies in the use of the radio spectrum have resulted in a saturation of the radio frequency ...
Hormigo Ventura, Juan Pedro (Data de defensa: 2020-11-25)
Urban tolls are nowadays one of the most promising instruments to regulate the entry of vehicles into cities, given the flexibility and versatility granted by the available technology. Although, initially, they represent ...
Solé Gustems, Miquel (Data de defensa: 2012-03-29)
La recogida actual de residuos de aparatos eléctricos y electrónicos (RAEE) es muy reducida, sobre todo para la categoría de los pequeños aparatos eléctricos y electrónicos. Con el objetivo de aumentar esta recogida, se ...
Díaz de Terán López, José Ramón (Data de defensa: 2013-09-12)
Durante los últimos años se han venido realizando viaductos con cimbra autolanzable y una nueva secuencia evolutiva de la sección transversal. Esta nueva secuencia evolutiva consiste en alcanzar un esquema autoportante que ...
Michiardi, Alexandra (Data de defensa: 2006-02-24)
Desde que fueron descubiertas en el principio de los años sesenta, las aleaciones con memoria de forma de NiTi han suscitado un interés creciente. Hoy en día, estos materiales se emplean extensivamente en el campo biomédico. ...
Rossini, Francesco (Data de defensa: 2014-06-05)
The topic discussed in this dissertation is the study of the public spaces in Hong Kong. In recent decades the city has established itself as a major financial centre and production, aiming to be one of global cities of ...
Monterde Gascón, María Carmen (Data de defensa: 2023-02-27)
(English) The transition towards to low carbon energy generation is promoting the installation of renewable energy sources, their successful deployment requires efficient energy storage systems in order to meet demand. ...
Mora Acosta, Josue (Data de defensa: 2001-12-20)
The target of this work is to contribute to the enhancement of numerical methods for the simulation of complex thermal systems. Frequently, the factor that limits the accuracy of the simulations is the computing power: ...
Sadurní Caballol, Alexandre (Data de defensa: 2012-09-28)

Albareda Valls, Albert (Data de defensa: 2013-01-18)
Concrete-filled tubes have been increasingly used these recent decades thanks to their improved structural behavior, especially under compression.Concrete filling in these sections improves ¡ts compressive strength thanks ...
Casas González, Guillermo (Data de defensa: 2018-10-30)
In this work we study the numerical simulation of particle-laden fluids, with a focus on Newtonian fluids and spherical, rigid particles. We are thus dealing with a multi-phase (more precisely, a multi-component) problem, ...
Irazábal González, Joaquín (Data de defensa: 2017-10-06)
The development of high-speed train lines has increased significantly during the last twenty-five years, leading to more demanding loads in railway infrastructures. Most of these infrastructures were constructed using ...
