Esta tesis constituye un estudio detallado y exhaustivo de las propiedades de una variedad específica de ondas ópticas solitarias. Observadas experimentalmente por primera vez en 1995, estas ondas estan formadas por un ...
The mid-infrared (mid-IR) spectral region, with wavelengths between 3 and 15 µm, is known for a wide range of applications ranging from spectroscopic sensing to thermal imaging. However, despite the strong technological ...
(English) This thesis describes theoretical background, simulations, experimental apparatus and measurements of nuclear spin dynamics via optically pumped magnetometers in unconventional magnetic field regimes. It is divided ...
Walking impairment after spinal cord injury leads to a decreased quality of life, other serious health conditions, and substantial health care costs. Consequently, gait restoration is a high priority among spinal cord-injured ...
By 2025, the Food and Agriculture Organization of the United Nations predicts that two-thirds of the world population will experience water stress conditions. In addition, it is expected that world population will increase ...
Modular Multilevel Converters (MMCs) are a type of Voltage Source Converter (VSC) which have become the preferred topology choice for High Voltage Direct Current (HVDC) applications. Compare to its HVDC converter predecessors, ...
To measure quantum features in a classical world constrains us to extend the classical technology to the limit, inventing and discovering new schemes to use the classical devices, while reducing and filtering the sources ...
Energy and transportation sectors are going through major changes as a result of technological advances, depletion of fossil fuels and climate change. With regard to the energy sector, the future smart grid is expected to ...
The growth in traffic increased the pressure on the environmental sustainability of air transport. In this context, many research effort has been devoted to minimise the environmental impact in the different phases of ...
The task of geotechnical site characterization includes defining the layout of ground units and establishing their relevant engineering properties. This is an activity in which uncertainties of different nature (inherent, ...
Com a primera part del treball de tesis doctoral, s'ha presentat la descripció, implementació i estudi computacional d'un nou algorisme de resolució del problema de fluxos no lineals amb constriccions a banda lineals. ...
Esta tesis analiza el conjunto de operaciones que se realizan en una Terminal de Contenedores Marítima para crear un modelo que optimice el volumen de producción en función de costes, precios, estructura y recursos.<br/><br/>Para ...
This thesis discusses the development of a new methodology for 3D printing of TiO2 nanoparticles and its applications in air purification and hydrogen production. A dosage has been obtained that allows 3D printing by DIW ...
The current investigation is aimed to improve the planning, orientation, monitoring, control and evaluation of the autonomous activities which a student must realize with the support of a Virtual Learning Environment (VLE). ...
La tesis doctoral realizada se basa en el estudio Sistematizado de los fenómenos ligados a la distribución De productos fitosanitarios por pulverización en Plantaciones frutales adultas y de sus efectos de control sobre ...
The Dissertation's main aim is to establish a procedure for the optimization of space grid as a framed tube (spatial mesh) structural typology envelope for tall buildings given the increasing interest in this recent ...
(English) The introduction of autonomous vehicles in intralogistics has significantly increased in recent times. However, in the industry, a single autonomous vehicle is often not used, but several of them are needed to ...
En esta Tesis Doctoral se desarrollan los principios básicos que rigen el comportamiento dinámico de un cilindro de suspensión hidroneumática, concibiendo métodos que lo optimizan y explotan al máximo sus propiedades ...
Se ha definido la Arquitectura Vernácula como el universo auto construido de distintos pueblos que legan su testimonio constructivo y que sintetizan los valores arquitectónicos, sociales y culturales, aún vigentes en algunos ...
El documento base de este trabajo es el aprobado el 1 de marzo de 1996 por la comisión Europea que establece los criterios para la concesión de la ecoetiqueta a ropa de cama y camisetas de algodón o algodón-poliéster. Uno ...
