Els programes de simulació Monte Carlo de caràcter general s'utilitzen actualment en una gran varietat d'aplicacions.<br/>Tot i això, els models geomètrics implementats en la majoria de programes imposen certes limitacions ...
Volpe, Giovanni (Data de defensa: 2008-10-23)
The ability of detecting farces and torques at the micro-and nano-scale is fundamental. When this Thesis started, various scanning probe techniques had already been developed to probe the mechanical properties of microsystems. ...
Martínez González, Cristina (Data de defensa: 2009-01-30)
In this Thesis we have presented the results of a set of experimental investigations of the dynamics of delay-coupled semiconductor lasers. The characterization of these systems includes topics such as the processing of ...
Cusmin, Paul (Data de defensa: 2009-03-11)
The work presented here has been focused, basically, on the study of the SmA-N and N-I phase transitions of a group of liquid crystals, the alkyloxycyanobiphenyls (nOCB), in which, for some of them, as it is the case of ...
Fraga Rivas, Iria (Data de defensa: 2010-02-26)
Differential Scanning Calorimetry (DSC) is one of the most widely used thermal analysis techniques for the study of transitions and relaxation processes in polymers and also in other materials. It measures the heat flow ...
Martínez García, Julio César (Data de defensa: 2011-07-15)
The key features of dynamics of ultraslowing glass forming systems are their universality in diversity. Its origin is recognized as one of the greatest challenges of condensed matter physics and materials engineering in ...
Casanova Bustamante, Jordi (Data de defensa: 2011-11-03)
Classical nova explosions are stellar explosions that take place in close binary systems with an energy release only exceeded by gamma-ray bursts and supernova explosions. Matter from the white dwarf flows through the inner ...
Mas de les Valls Ortiz, Elisabet (Data de defensa: 2011-12-01)
In Nuclear Fusion Technology, MHD flows can be encountered in liquid metal (LM) breeding blankets, the part of a fusion reactor where tritium, one of the fusion fuels, is to be produced. There are several types of LM ...
Martínez Rovira, Immaculada (Data de defensa: 2012-03-12)
Two innovative radiotherapy (RT) approaches are under development at the ID17 Biomedical Beamline of the European Synchrotron Radiation Facility (ESRF): microbeam radiation therapy (MRT) and minibeam radiation therapy ...
González de Perosanz, Miguel Àngel (Data de defensa: 2012-03-19)
This research work has been developed in order to contribute to the knowledge of radioactive aerosol characteristics and their behaviour in the atmosphere. The study was carried out in the city of Barcelona. The Instituto ...
Grossi, Claudia (Data de defensa: 2012-03-30)
Es los últimos años se han llevado a cabo importantes trabajos de investigación, tomando el gas radón como elemento de evaluación en modelos de transporte atmosférico y así estimar el flujo de partículas. Además la utilización ...

Probabilistic Risk Assessment for the evaluation of procedures in the Nuclear Safety field. Application to a pressurized water reactor. The studies contained in this PhD are involved in the Nuclear Safety research field. ...
Marín Lacoma, Eduardo (Data de defensa: 2012-12-21)
The accelerator and particle physics communities are considering a lepton Linear Collider LC as the most appropriate machine to carry out high precision particle physics research in the TeV energy regime. The Compact Linear ...
Perrone, Sandro (Data de defensa: 2014-02-07)
This thesis is focused on the study of stochastic and nonlinear dynamics in optical systems. First, we study experimentally the dynamics of a Brownian nanometer particle in an optical trap subjected to an external forcing. ...
Bargalló Font, Enric (Data de defensa: 2014-05-09)
The planned International Fusion Materials Irradiation Facility (IFMIF) has the mission to test and qualify materials for future fusion reactors. IFMIF will employ the deuteron-lithium stripping reaction to irradiate the ...
Molina Giralt, Glòria (Data de defensa: 2014-05-09)
Historical decorated glass and glazed ceramics are studied with the object to determine the technology of production and to relate it with the optical properties (colour, shine, opacity). Four different case of study are ...
Aragoneses Aguado, Andrés (Data de defensa: 2014-06-18)
The aim of this thesis is the study of the dynamics induced by optical feedback in semiconductor lasers. This study aims, on the one hand, to improve our knowledge of stocahstic complex systems, and on the other hand, to ...
