Air transport, in 2018, was the means of transport chosen by 8.8 billion people around the world. This is a sector that expected continued passenger growth in the following years, but due to the current effects of the ...
La industria de la construcción está fragmentada debido a la gran cantidad de Pequeñas y Medianas Empresas (PYMEs) y la multitud de fases que forman parte de un proyecto. Desde siempre, esta situación ha provocado una serie ...
La industria es comúnmente vista como una fuente de degradación ambiental y de consumo de recursos, a pesar de ello es una parte vital del desarrollo social y de la creación de riqueza. Del mismo modo, los sistemas ...
(English) The sixth-generation (6G) network's evolution necessitates advancements in algorithms and architecture to transition from an AI-native to an intrinsic trustworthy automation-native system. Network slicing creates ...
(English) To mitigate the present environmental crisis, caused by the excessive use of fossil fuels and associated release of carbon dioxide into the atmosphere, it is necessary to significantly reduce worldwide energy ...
This thesis deals with sunny side-lit indoor atmospheres, in which an outdoor view is required and a calm environment to enhance concentration. Different window systems were compared: a single fully glazed façade and complex ...
Recent advancement in Photonics have brought about a new era of miniaturisation. Along came a need for technology to allow the manipulation of light at the micrometer scale, with precise control over beam propagation. The ...
In this century some of our main issues are energy shortage and pollution. This work will briefly describe these problems, proposing a plan of action combining energy saving and different sustainable energy sources. Within ...
Disordered media with refractive index variations can be found in the atmosphere, the ocean, and in many materials or biological tissues. Several technologies that make use of such random media, as image formation, satellite ...
The environmental issues associated with the use of conventional fuels necessitates the utilisation of renewable energy sources, as well as the implementation of energy efficient designs, in order to decrease electricity ...
Considering that the most abundant renewable energy source is the Sun, photovoltaic technology possesses one of the highest potentials to provide environmental benign and sustainable energy worldwide. Currently, most of ...
The quest for new artificial structures and materials uncovers novel new light-matter interactions, and intriguing physical phenomena. Since the late 80’s purely dielectric materials have been structured, at the wavelength-scale, ...
Conformance Checking is a new research discipline devoted to identify deviations between business process models and their real executions. Identifying deviations boils down to the notion of alignment conceptually. An ...
(English) The study of quantum light-matter interaction with atomic ensembles is an active research area. This kind of system allows fundamental studies on measurement in the context of continuous variables, in collective ...
Executable models play a key role in many development methods (such as MDD and MDA) by facilitating the immediate simulation/implementation of the software system under development. This is possible because executable ...
(English) Rare earths elements (REE) are crucial elements to the future of technology, particularly to the power generation and road transport. One of the most sustainable processes to recover rare earths is biosorption. ...
En esta tesis, se ha intentado sustituir el uso de los solventes orgánicos clorados peligrosos con la técnica de la extracción supercrítica para la limpieza de piezas metálicas porosas. Se ha estudiado experimental y ...
Nowadays, the need for ethical behavior in society is unquestionable due to dominant social problems that concern society, such as poverty, inequality and climate change. These issues have been addressed by private and ...
(English) Lignocellulosic biomass is an abundant renewable resource considered a suitable carbon raw material for the synthesis of chemicals and as an alternative to fossil fuels energy supply source. Cellulose, hemicellulose, ...
Els objectius principals d'aquesta tesis són l'avaluació del rendiment a nivell d'enllaç i l'estudi de l'abstracció de l'enllaç pel LTE/LTE-Advanced DL. S’ha desenvolupat un simulador del nivell d'enllaç E-UTRA DL basat ...
