Parametrització d'una bomba d'engranatges externs i validació en condicions reals
(English) Pumps of positive volumetric displacement (PDVP) drive a volume of fluid from suction to discharge for each revolution of its shaft, called derived capacity, and therefore, in an ideal constant capacity pump the ...
Solution-processed quantum dot infrared lasers
(English) Colloidal semiconductors quantum dots (CQDs) have emerged as a promising solutionprocessed gain material that can be engineered via low-cost and scalable chemical techniques. Owing to quantum confinement, their ...
Attosecond soft X-ray absorption revealing the ultrafast non-adiabatic dynamics of furan
(English) One of the fundamental goals of the physical chemistry community has always been to be able to follow the details of the evolution of chemical reactions in real-time. Besides the extreme temporal resolution ...
Strategies for improving resilience in distributed communication systems
(English) With the development of industry and society, new verticals have emerged such as Industry 4.0, cooperative sensing, and massive IoT. These verticals require network robustness and availability to maintain high ...
Strategies for UPF placement in 5G and beyond networks
(English) This doctoral thesis focuses on the design of strategies (i.e., exact and heuristic-based methods) to optimize the placement and reconfiguration of user plane functions (UPFs) in 5G and beyond networks. These ...
Energy and material circularity in building-integrated agriculture : an environmental approach
(English) Cities are great resource consumers and largely contribute to anthropogenic environmental impacts, urgently requiring a decarbonization plan. Urban agriculture lies on industrial ecology principles; waste resources ...
Bioresorbable Zn-based alloys for biomedical applications
(English) Biodegradable metals emerged as promising materials for bioresorbable devices avoiding the potential side effects of permanent implants. Among them, zinc (Zn) arose dueto its suitable degradation rate for biomedical ...
SFC placement and lifecycle management in edge-enabled 5G architectures
(English) The fifth generation (5G) of mobile communications urges software defined networking (SDN) and network function virtualization (NFV) to join forces with the multi-access edge computing (MEC) cause. Thus, reduced ...
Eco-friendly solar cells with cation-engineered AgBiS2 nanocrystals
(English) Climate change and global energy demand urge the development of renewable energy sources for worldwide power supply. Photovoltaic devices that convert solar energy directly into electricity are the most promising, ...
Development and clinical applications of a whole anterior segment and retinal SS-OCT
(English) Vision is central to human perception. It emanates from a complex organ, the human eye, starting from photodetection in the retina. However, the quality of the visual experience depends on the anatomical integrity ...
Cluster evaluation on weighted networks
(English) This thesis presents a systematic approach to validate the results of clustering methods on weighted networks, particularly for the cases where the existence of a community structure is unknown. Including edge ...
Shedding light on sewer pipes : deep learning perception approaches for autonomous sewer robots
(English) Sewerage is a vital infrastructure for society’s day-to-day life. Its maintenance is a priority and current European legislation increases the demand of a proper inspection. Being a complex access and dangerous ...
Theoretical and experimental investigation on the visible-light controlled functional properties in charged domain wall ferroelectrics
(English) Optical control of ferroelectric properties has been attracted a growing interest as an alternative to the conventional control by applied electric fields. However, the major drawback for achieving an effective ...
Understanding secondary emission processes and beam matter interactions for optimization of diagnostic wire grid system in particle accelerators : thermal modeling for beam power limits calculation
(English) Thin targets, in form of foils, stripes or wires, are widely used in beam instrumentation to measure various beam parameters, such as intensity, position and size. All these monitors can differ in geometry and ...
New data integration methods for drug re-purposing by mining heterogeneous omics data
(English) High-throughput omics technologies produce large-scale heterogeneous data that provide complementary views of the underlying complexity of the studied organism. To exploit these new data to answer biomedical ...
Estudio numérico y comparativo del comportamiento de columnas tubulares mixtas con un pretensado inicial de uno de los componentes : aproximación experimental del comportamiento de secciones CFST pretensadas, sometidas a compresión cíclica
(English) The use of mixed structures of the most varied types and typologies, mainly in steel and concrete, have been increasingly used in the recent decades. The mechanical advantages of these structures in comparison ...
Enhanced air traffic flow and capacity management under trajectory based operations considering traffic complexity
(English) The Air Traffic Flow and Capacity Management (ATFCM) aims at maintaining the forecast traffic demand below the estimated capacity in airports and airspace sectors. The purpose is to maintain the workload of the ...
Environmentally-friendly perovskite nanocrystals based on titanium and tin
(English) The availability of energy is a fundamental ingredient for the development of society. However, the intense consumption of fossil fuels as an energy resource since the second industrial revolution has caused a ...
First order logic of random sparse structures
(English) This work is dedicated to the study several models of random structures from the perspective of first-order logic. We prove that the asymptotic probabilities of first-order statements converge in a general model ...
Fluorescence quantum yield and the open circuit voltage in perovskite solar cells
(English) To mitigate the energy and climate crisis we are already facing and address the increasing energy consumption, it is essential to foster energy transition strategies. The energy transition success largely depends ...
