Steganographic methods for information hiding in MS-Office files
(Universita degli studi di Salerno, 2013-04-20)The simplest container of digital information is “the file" and among the vast array of files currently available, MS-Office files are probably the most widely used. These files, starting from MS-Office 2007, respect the ... -
On the Generalizations of Identity-Based Encryption
(Universita degli studi di Salerno, 2013-04-16)Today public-key cryptographic is widely deployed and successfully used but still a major drawback exists. In fact, from encrypted data a party can either decrypt or cannot learn anything at all about the message other ... -

(Universita degli studi di Salerno, 2013-04-02)Nella notte tra il 24 e 25 agosto del 79 d.C. villaggi e città vennero distrutti e migliaia di persone persero la vita per l' improvvisa eruzione del Vesuvio. Le rovine di Pompei ed Ercolano, sepolte e conservate dai ... -
Interplay of spin-orbital correlations and structural distortions in Ru- and Cr- based perovskite systems
(Universita degli studi di Salerno, 2012-07-02)The transition metal oxides are emerging as the natural playground where the intriguing effects induced by electron correlations can be addressed. Since the s electron of the transition metals are transferred to the ... -
High-sensitivity strain measurements from underground interferometric stations: geodynamic phenomena at Gran Sasso and first records from Canfranc
(Universita degli studi di Salerno, 2013-03-11)Earth's surface and interior continuously deform as a result of geological and geophys- ical processes. To study these phenomena and to understand better the rheological properties of the Earth, measurements of Earth's ... -
Quantumness of gaussian and non-gaussian states in the optical domain
(Universita degli studi di Salerno, 2013-04-04)The Dissertation Quantumness of Gaussian and non-Gaussian states in the op- tical domain collects my personal both theoretical and experimental contribu- tions, in the context of the Quantum Information theory in continuous ... -
Network anaomaly detection based on the observation of multi-scale traffic dynamics
(Universita degli studi di Salerno, 2012-03-03)Con la sempre più rapida crescita in termini di dimensioni e complessità delle moderne infrastrutture di rete, l’attività di individuazione e prevenzione di abusi e violazioni nell’uso di tali infrastrutture sta diventando ... -
Synthesis and properties of linear and cyclic peptoids
(Universita degli studi di Salerno, 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 ... -
New catalysts for ring-opening polymerization of cyclic esters
(Universita degli studi di Salerno, 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 ... -
From GeoVisualization to visual-analytics: methodologies and techniques for human-information discourse
(Universita degli studi di Salerno, 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 ... -
On the formulation of Einstein general relativity in a phisycal reference system
(Universita degli studi di Salerno, 2012-04-06)The research deals with the breaking of the evolution problem of a reversible material system in two different problems, the initial data problem and the restricted evolution problem. This breaking, intrinsically formulated, ... -
Nb nanoporous ultrathin films: matching effects and interconnected wires
(Universita degli studi di Salerno, 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 ... -

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 ... -
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 ... -
