Light-matter interaction with atomic ensembles
(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 ...
Tool-part tribological interaction assessment for continuous deformation processes
(English This dissertation is an experimental assessment of the tool-part tribological interaction of continuous deformation processes: ball burnishing as a superfinishing process and wire drawing as a bulk deformation ...
Structural behaviour of stainless steel frames. Safety against accidental seismic actions
(English) Stainless steel is one of the most promising construction materials due to its long service life, low maintenance requirements, excellent mechanical properties and high residual value. Nevertheless, for an efficient ...
On the data quality improvement of air pollution monitoring low-cost sensor networks using data-driven techniques
(English) Nowadays, authorities monitor the concentrations of regulated air pollutants in order to assist in decision-making processes, e.g., for the implementation of traffic restrictions, and mitigate the effects of air ...
Estudio teórico y experimental sobre el comportamiento no lineal de estructuras continuas parcialmente pretensadas
(English) Performance-based design (PBD) is a philosophy for structural design that puts emphasis on the realistic estimation of the structural behaviour and its relationship with the objectives of the final user, or ...
Efectos a largo plazo de la descarga de las aguas residuales procedentes de los sistemas de limpieza de los gases de escape de ciclo abierto sobre el nivel de acidez de las aguas del Puerto de Barcelona : análisis de la situación actual, evolución y propuestas para combatir los efectos perjudiciales causados por la descarga de las aguas de lavado
(English) This thesis is focused on analysing the impact produced by washwater discharges from exhaust gas cleaning systems fitted on ships on the pH level of Barcelona port waters. These systems are being used on board ...
Impulse maneuver design for a solar sail spacecraft in the restricted three-body problem framework
(English) A solar sail is a method of spacecraft propulsion that uses only the solar radiation pressure (SRP). The main research object of this thesis is a solar sail spacecraft in the artificially created libration point ...
Para una sociología de la intelectualidad outsider : manierismo (1964), de Arnold Hauser, y los marxismos heterodoxos
(English) Mannerism is one of the most contentious concepts in the history of Western art, and it is significant that an author as controversial as Arnold Hauser (1892-1978) devoted a good part of his efforts to it. The ...
Three-dimensional SPH simulations of the interaction between the nova ejecta and the companion star
(English) Classical and Recurrent novae are thermonuclear explosions hosted by accreting white dwarfs in stellar binary systems. Material piles up on top of the white dwarf star under mildly degenerate conditions, driving ...
The value of urban community public space - from Barcelona to Chongqing
(English) The community is the main urban space for expressing public space, and it is quite related to the daily life of everyone. In China, the community associated with housing became much more complex than before in ...
Optical parameter sensing: sensitivity limits and the advantages of using spatial modes of light
(English) Resolution enhancement in modern optical metrology techniques has been possible due to significant technological improvements. The accurate and precise control of wavelength, bandwidth, and power of light sources; ...
Improving monitoring and management of low-lying coastal areas with Sentinel-2 data: the Ebro Delta showcase
(English) Coastal areas support important ecosystems with great ecological value, giving rise to countless resources increasingly exploited by humans. Understanding the processes occurring in both inland and aquatic ...
Cylindrical microplane model for fiber reinforced polymer composites
(English) Fiber-reinforced polymers (FRPs) are the most used composite materials in many applications, from broom handle to the main structure of advanced aircraft. Despite the enormous research done on these materials, ...
Optical holographic microscopy for bio- and nanoparticle characterization
(English) Nowadays, being able to precisely characterize nanoparticles is of key relevance in a wide range of scenarios. For instance, chemical and pharmaceutical industries often rely in particle-sizing for quality control. ...
Advanced single molecule fluorescent tools to reveal spatiotemporal multi-molecular interactions in living cells
(English) The spatiotemporal organisation and compartmentalisation of molecules in living cells is crucial to regulate cell function. Dysregulation in how molecules dynamically explore their environment and interact with ...
Viewability contributions towards a better online advertising ecosystem
(English) Online advertising makes possible most of the freely available online content and services. However, it is far from being mature and there are still controversial topics that need to be addressed. One of these ...
Nanophotonics with charged particles
(English) Among the fundamental constituents of matter, charged particles such electrons and positrons are leading protagonists in physical phenomena associated with small (~ meV) and high (~ MeV) energy scales. For example, ...
Influencia del comportamiento cromático de las lentes intraoculares en la función visual
(English) Diffractive multifocal intraocular lens typically uses a hybrid refractive-diffractive design that consist of a high-power refractive base lens and a low-power diffractive profile engraved on one of its surfaces. ...
Practical strategies to monitor and control contention in shared resources of critical real-time embedded systems
(English) In the last decade performance needs in Critical Real-Time Embedded Systems (CRTES) domains like automotive, avionics, railway or space have been steadily on the rise due to the unprecedented computational power ...
Modelling and predicting extreme behavior in critical real-time systems with advanced statistics
(English) Critical Real-Time Embedded Systems (CRTES) are used in domains like transportation (e.g. avionics, automotive, space, and railway), healthcare, and industrial machinery. This subset of embedded systems requires ...
