The revolution of ICT technologies in Digital Era combined with progress of ComplexitySciences have lead to the emergence of Computational Social Science, whose purposeis to analyze society in a quantitative way. ...
In some types of fire, namely, smoldering fires or involving polymers without flame, gases and volatiles appear before smoke is released. Most of the fatalities registered for fires, are caused due to the intoxication of ...
Two decades ago, microfluidic technology begun to make its appearance in the fields of drug delivery and biomedical engineering to irrevocably revolutionize them. It was quickly realized how microchannels can aid formulation ...
Most of the real-world complex systems are best described as complex networks and can be mathematically described as oscillatory systems, coupled with the neighbours through the connections of the network. The flashing of ...
En aquesta tesi s’ha desenvolupat un mètode de mesura de la funció de transmissió òptica policromàtica d’instruments fotogràfics (sistema constituït per la lent formadora de la imatge i la placa de registre fotogràfic). ...
[eng] This thesis focuses on the functional design and preparation of different kind of nanocomposites and their applications in energy conversion and storage technologies, particular in OER, HER, H2O2ER and LSBs. For the ...
Complex networks are mathematical representations of the interaction patterns of complex systems. During the last 20 years of Network Science, it has been recognized that networks from utterly different domains exhibit ...
Living organisms and systems are continually converting energy, either internally stored or transduced from their surroundings, into motion. This activity and the resulting self-propulsion constantly push these biological ...
Multiple initiatives are being implemented to mitigate and, in the worst-case scenarios, adapt society to climate change. The vast majority consider renewable energies key to accomplishing a necessary transition from fossil ...
With the burning of large amounts of traditional fossil fuels, global environmental pollution is getting worse and worse, and energy crisis is becoming more serious for meeting human’s life demand. In ...
This thesis describes some results in AdS/CFT duality for quantum field theories in 2+1 and 1+1 dimensions. In first place, a one-parameter family of supergravity solutions is described, obtained as a deformation of a ...
Cosmological thermal first-order phase transitions are assumed to proceed via the nucleation of bubbles and subsequent expansion and collision. The out-of-equilibrium physics involved during the collision of bubbles is ...
CONTEXT: The current ΛCDM cosmological paradigm has seen remarkable success in recent decades (whether it is the discovery of the CMB, the formation of large-scale structures, the expansion of the universe etc.). Like any ...
The topics dealt with in this thesis are all part of the general problem of social consensus, namely how a convention flourish and decay and what motivates people to conform to it. Examples range from driving on the right ...
Hybrid bio-robotics is a discipline that aims at integrating biological entities with synthetic materials to incorporate features from biological systems that have been optimized through millions of years of evolution and ...
The goal of this thesis is studying hydrodynamic effects on active colloidal suspensions. Hydrodynamic interaction is propagated through the fluid in which the colloids displace due to the flow they create during their ...
Conventional in vitro cell culture models do not possess the complexity that the native tissues offer. Because of this, the functional properties of the tissues are not properly mimicked, which causes poorly predictive ...
A Metal-insulator transition (MIT) is the ability of some materials to change between metal and insulator electric behaviours as a function of some external stimuli such as temperature, stress, voltage, magnetic field or ...
[eng] Owing to its exceptional topographical resolution and electrical sensitivity, Conductive Atomic Force Microscopy (C AFM) has become an essential tool for nanoscale material analysis. However, achieving reproducible ...
ROS (Reactive Oxygen Species), such as H2O2, HO● and O2-●, are naturally produced by the metabolism of living beings. However, they can appear in large quantities in the case of certain diseases (Alzheimer's, Parkinson's, ...
