Monitoring and mining real-time network data streams are crucial operations for managing and operating data networks. The information that network operators desire to extract from the network traffic is of different size, ...
In the first part, we formally study the phenomenon of the so-called big bang bifurcations, both for one and two-dimensional piecewise-smooth maps with a single switching boundary. These are a special type of organizing ...
In the context of distributed generation growth, local grids could face operational issues. In that sense, smart grid deployment will give information to local grid operators about grid status at medium and low voltage ...
In order to increase the performance of particle colliders, it is crucial to make the beam sizes at the collision points as small as possible. This causes an increase of the beam size in the region surrounding the collision ...
Many materials of scientific interest show a disordered phase, with their molecules presenting positional disorder, orientational disorder or both. Processes of interest to life also occur in these kind of phases as it is ...
This thesis aims at improving the convergence of iterative solvers, used for algebraic systems coming from the discretization of partial differential equations (PDE), in the context of large scale simulations and high ...
Air pollution is an important topic with a great social impact; it is related with public health, environment and ecology, and climate change. Scientists have developed several models in the last thirty years, and regional ...
Quantum Mechanics was established as the theory of the microscopic world, which allowed to understand processes in atoms and molecules. Its emergence led to a new scientific paradigm that quickly spread to different research ...
(English) Nowadays, lightning presents a challenge to the proper functioning of an increasingly complex electrical system. One of the most sensitive and exposed to lightning elements are wind turbines. Due to their height ...
When GPS is not operative in closed environments, mobile robots use different types of sensor in order to locate their position. However, the use of audiofrequency signals sensors is significative lower than other type of ...
In recent times, metallic nanoparticle plasmonics coupled with applications towards biosensing has gathered momentum to the point where commercial R&D are investing large resources in developing the so-called localized ...
This thesis proposes a new computational model for the efficient simulation of crack propagation, through the combination of a phase-field model in small subdomains around crack tips and a discontinuous model in the rest ...
Over the course of 60 years, since the invention of the integrated circuit (IC), exponential improvements in cost, performance and power consumption were observed. Such advances have been strongly linked with the continuous ...
Long Term Capacity Planning (LTCP) consists of deciding the type and amount of capacity of production systems for multiple periods in a long term planning horizon. It involves decisions related to strategic planning, such ...
The main objective of this thesis is to achieve an improved understanding of the thermo-hydro-mechanical processes and material properties that affect how the gaps and canister) behave during and after installation in the ...
This PhD thesis is concerned with evaluating the long-term effects of interventions in the editorial peer review process of a biomedical journal. The growing need to increase the value of research and avoid waste motivates ...
This PhD thesis focuses on lattice-based cryptography and how to apply it to build post-quantum online voting systems. It is the result of the research done by the author at Scytl in close collaboration with Dr. Paz Morillo, ...
En 1409, seis años después de la inundación del barrio del Raval de Mar, los mercaderes solicitaron al rey permiso para construir una lonja que “ennobleciera su profesión y la Ciudad de Mallorca”. No fue hasta 1426 cuando ...
Developing efficient programs for many of the current parallel computers is not easy due to the architectural complexity of those machines. The wide variety of machine organizations often makes it more difficult to port ...
Nowadays almost all the expert opinion agrees that the cities -and the way of life that they carry- are the best solution to continue housing a growing world population. We know that the compactness of each city is directly ...
