Labarta, Amílcar (Data de defensa: 1985-11-29)
Los trabajos de esta memoria persiguen un doble objetivo. Por un lado se ha pretendido ahondar en modelos de campo cristalino para cationes 3d(n) y su correlación con los datos experimentales, de sustancias de interés ...
Planes Vila, Antoni (Data de defensa: 1981-05-11)
En este trabajo se presenta un estudio experimental de la transformación martensítica de la aleación ternaria Cu Zn Al. El estudio ha sido realizado mediante el uso de un dispositivo de medida, original, que permite ...
Cornet i Calveras, Albert (Data de defensa: 1987-05-18)
En la pasada década, se han observado nuevas bandas de luminescencia en los semiconductores cuando son excitados fuertemente por medio de láseres (fotoexcitacion). La interpretación del origen de estas bandas era variado ...
Masoliver, Jaume, 1951- (Data de defensa: 1983-01-21)
En esta Tesis se llega a resultados originales relacionados con las propiedades dinámicas de las sistemas de muchos cuerpos o grados de libertad. En particular se estudian propiedades estocásticas y ergódicas de modelos ...
Kleineberg, Kaj Kolja (Data de defensa: 2016-06-27)
Online social networks (OSNs) enable researchers to study the social universe at a previously unattainable scale. The worldwide impact and the necessity to sustain their rapid growth emphasize the importance to unravel the ...
Palacios Ruiz, Lucas Santiago (Data de defensa: 2022-03-04)
This thesis contains my doctoral research in condensed soft matter physics prepared at the University of Barcelona. It covers the interaction of active Janus particles with liquid-liquid and liquid-solid interfaces, both ...
Gutiérrez-Roig, Mario (Data de defensa: 2016-01-28)
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. ...
Solorzano Soria, Ana Maria (Data de defensa: 2020-03-05)
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 ...
Glinkowska Mares, Adrianna (Data de defensa: 2021-09-09)
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 ...
Rosell Tarragó, Gemma (Data de defensa: 2022-06-16)
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 ...
Bosch i Puig, Salvador (Data de defensa: 1984-06-27)
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). ...
Du, Ruifeng (Data de defensa: 2022-06-30)
[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 ...
García Pérez, Guillermo (Data de defensa: 2018-11-16)
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 ...
Katuri, Jaideep (Data de defensa: 2018-09-20)
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 ...
Ramon Gamon, Jaume (Data de defensa: 2022-01-27)
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 ...
Han, Tingting (Data de defensa: 2020-12-11)
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 ...
Pravos Fernández, David (Data de defensa: 2019-11-08)
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 ...
Sanchez Garitaonandia, Mikel (Data de defensa: 2022-07-15)
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 ...
Valcin, David (Data de defensa: 2021-09-28)
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 ...
Amato, Roberta (Data de defensa: 2018-04-13)
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 ...
