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 ...
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 ...
The main object of this Thesis is the study of the dynamical coupling between cellular processes, and how this coupling gives rise to a well-defined behavior in the presence of non-linearities and noise. Cell functioning ...
CERN is presently constructing the LHC, which will produce collisions of 7 TeV protons in 4 interaction points at a design luminosity of 1034 cm-2 s-1. The radiation dose resulting from the operation at high luminosity ...
A partir de un simulador previo de cultivos bacterianos, se ha continuado desarrollando su metodología, basada en la simulación discreta, para extender su uso a diversos campos de aplicaciones técnicas y científicas. un ...
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 ...
Se presenta el trabajo realizado sobre el paquete de Subrrutinas Penélope. Este código permite la simulación MC del transporte de fotones y electrones en la materia con geometrías complejas. Los aspectos considerados ...
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 ...
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 ...
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 ...
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 ...
El objetivo de esta tesis es el estudio de la dinámica de los láseres de semiconductor (LS) con realimentación óptica, tanto desde el punto de vista experimental como numérico. La reflexión de la luz emitida por el láser, ...
El treball Estudi de sals foses mitjançant la dinàmica molecular està integrat dins la línia de recerca Simulació de comportament atòmic en la matèria condensada i amb ell s'han assolit dos grans objectius. El primer ...
El término carga de espacio describe el estado eléctrico de un material, mal conductor, que mantiene una distribución de cargas eléctricas relativamente inmóviles. El estudio del efecto de la carga de espacio sobre las ...
Los resultados que se analizan en este trabajo proceden fundamentalmente de dos polímeros (PET, PEN) y hemos utilizado esencialmente la técnica TSC centrándonos en el comportamiento de los mecanismos de conducción ligados ...
En la investigació de la fusió termonuclear controlada per confinament magnètic es important conèixer el transport d'energia en els plasmes, doncs aquest transport és el que fa que es refredi més o menys ràpidament amb el ...
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. ...
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 ...
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. ...
In this work beta-decay half-lives and neutron-emission probability values have been experimentally determined for first time in several nuclei beyond the neutron-shell closure at N=126. To this aim the accelerator complex ...
