Nb nanoporous ultrathin films: matching effects and interconnected wires
(2012-03-03)
When the applied magnetic field is higher than the lower critical field but below
the upper critical field, a type-II superconductor allows magnetic flux to penetrate it
in the form of vortices, a tiny normal area surrounded ...
Dissipation, mixing and two level system in quantum field theory
(2012-04-30)
In this dissertation we discuss several aspects of a two level system (qubit) in the context of quantum mechanics and quantum field theory. The presence of geometrical phases in the evolution of a qubit state is shown. We ...
Some topics on fuzzy logic
(2010-05-04)
Si trattano diversi aspetti della logica fuzzy, in particolare: 1) le proprietà preservate da un modello fuzzy ogniqualvolta esso è sottoposto a qualche genere di modifica; 2) la programmazione logica fuzzy, la logica della ...
Trasporto quantistico di spin in eterostrutture magnetiche
(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 ...
Magnetic orbital and transport properties in LaMnO3 based based heterostructures
(2011-05-13)
This thesis work deals with the magnetic, orbital and transport properties of (LaMnO3)2N(SrMnO3)N digital superlattices and of LaxMnO3-d thin films, both deposited by molecular beam epitaxy (MBE) technique on SrTiO3 ...
Synthesis and properties of linear and cyclic peptoids
(2012-03-26)
Le strutture e le attività metaboliche di tutte le cellule si basano su una vasta gamma di molecole comprendenti: amminoacidi, carboidrati, lipidi e nucleotidi, insieme alle forme polimeriche di questi composti. Ognuna di ...
From GeoVisualization to visual-analytics: methodologies and techniques for human-information discourse
(2012-04-03)
The objective of our research is to give support to decision makers when facing problems which require rapid solutions in spite of the complexity of scenarios under investigation. In order to achieve this goal our studies ...
Redox proteins for the development of biosensors
(2011-02-21)
In recent years the field of chemical sensors and optical biosensors has been developed considereably. A biosensor is a device composed of a biological component (Borisov and Wolfbeis 2008) that interacts with a target ...
Simulation and optimization of crowd dynamics using a multiscale model
(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 ...
New catalysts for ring-opening polymerization of cyclic esters
(2012-02-16)
The Ring-Opening Polymerization of cyclic esters by metal complexes via coordination-insertion mechanism represents the most effective and versatile method for preparing aliphatic polyesters with a good control in terms ...
