The ground deformations: tools, methods and application to some Italian volcanic regions
(Universita degli studi di Salerno, 2012-06-13)The objective of this thesis is the study of slow deformation of the soil as a result of intrusion of magma inside the magmatic chambers of some volcanoes located in Southern Italy. In particular, the Mt. Vesuvius and Campi ... -
Simulation and optimization of crowd dynamics using a multiscale model
(Universita degli studi di Salerno, 2012-04-11)In the last decades, the modeling of crowd motion and pedestrian .ow has attracted the attention of applied mathematicians, because of an increasing num- ber of applications, in engineering and social sciences, dealing ... -
Trasporto quantistico di spin in eterostrutture magnetiche
(Universita degli studi di Salerno, 2012-06-04)In questa tesi abbiamo studiato il trasporto di spin polarizzato e la torsione dello spin usando l’apporoccio della matrice di scattering secondo la teoria di Buttiker, nel caso di barriere magnetiche finite sotto l'effetto ... -
Electric transport properties of S/F hybrids: weak and inhomogenous ferromagnet
(Universita degli studi di Salerno, 2012-03-30)Superconductivity (S) and ferromagnetism (F) are competing phases whose coexistence is unlikely to occur. Exceptions require a non−uniform profile both for the pairing and the magnetization, as in the case of the FFLO state ... -
