In this thesis, the results of different core-shell structures are presented after having been synthesized by the modified Stöber method, results of UV-Vis, SEM, TEM, XRD, among others, are shown, which determined the ...
The invention of the laser triggered the study of light-matter interactions. In turn, the advent of artificial structured materials on micro- and nanometer scales has become a fruitful playground to tailor the propagation ...
This thesis focuses on the thermodynamic and crystallographic characterization of C60 solvates formed with small organic molecules (CBr2(CH3)2, CBr2Cl2, CBr2H2, CBrCl2H and CBrClH2) Chapter I provides an introduction ...
The motion of space objects is strongly nonlinear and non-integrable since it is not only affected by the Keplerian central gravity of the Earth, but also subjected to some complex perturbations. Either an accurate and ...
(English) The availability of RADAR images for monitoring Earth’s surface and its changes over time prompt the development of several interferometric SAR (InSAR) algorithms and methodologies. The Multi-temporal InSAR ...
The brain is a complex multiscale dynamical system made of neurons, connected with each other by synapses. Neurons are multidimensional nonlinear systems able to exhibit dynamical activities at different temporal and spatial ...
The aim of this thesis is to deepen into the understanding of the mechanisms responsible for the generation of complex and stochastic dynamics, as well as emerging phenomena, in the human brain. We study typical features ...
(English) New research shows that global demand for alloys with unique properties for various applications increased drastically, and among all them the demand for high entropy and metallic glasses in the industry is ...
Aerobiology is the science that focuses on the study of the airborne living organisms (bacteria, fungal spores, pollen, small insects, etc.). The influence of meteorology and climate change on plant phenology include shifts ...
Dynamical instabilities which lead to spontaneous pattern formation are present in a wide variety of nonlinear dynamical systems, both in nature as well as in technological areas. The instabilities may be saturating, leading ...
Optical excitable systems that mimic neuronal behavior have potential to be building-blocks of novel, ultra-fast, neuron-inspired photonic information processing systems. In particular, semiconductor lasers with optical ...
Free-route airs pace perm its us ers to freely plan a route between defined entry and exit waypoints with the pos s ibility of routing 1.fa intermediate points. Flights flyíng in a free-route area remain subject to air ...
(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 ...
The LISA Pathfinder project is an ESA/NASA technology demonstrator mission that must test the critical instrumentation required for a future space-borne gravitational wave observatory based on the LISA design. The satellite, ...
(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 growth in air traffic has led to a continuously growing environmental sensitivity in aviation, encouraging the research into methods for achieving a greener air transportation. In this context, continuous descent ...
(English) Turbulence is not only omnipresent in our daily lives but also in engineering applications. However, not until the middle of the XXth century researchers began to realize that simple, relatively large-scale ...
Supercomputing, also known as High Performance Computing (HPC), is almost everywhere (ubiquitous), from the small widget in your phone telling you that today will be a sunny day, up to the next great contribution to the ...
The object of study of this thesis are dipolar systems in the quantum degenerate regime. In general, dealing with many-body systems and evaluating their properties requires to deal with the the Schrödinger equation. In the ...
Control is important for transferring theoretical scientific knowledge into practical technology for applications in numerous fields. This is why coherent control study is significant on every timescale to have a complete ...
