New chemical topologies based on calixarene threading
(Universita degli studi di Salerno, 2014-03-11)Recently, Neri et al. have introduced an efficient method to obtain endo-cavity complexation and through-the-annulus threading of large calixarenes by exploiting the inducing effect of the weakly coordinating tetrakis[3, ... -
Le potenzialità dell’e-learning nell’apprendimento della matematica
(Universita degli studi di Salerno, 2011-02-18)La tesi indaga e discute le potenzialità dell’e-learning nell’apprendimento della matematica. Oggi la tecnologia dell’informazione e della comunicazione non è più strettamente legata a qualche quadro teorico. In passato ... -
Imbedding and compactness results in some function spaces
(Universita degli studi di Salerno, 2011-03-16)Abstract Nello studio di vari problemi ellittici con soluzioni in spazi di Sobolev S( ) (con o senza peso) definiti su un aperto di Rn, non necessariamente limitato o regolare, spesso risulta necessario stabilire ... -
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 ... -
Numerical treatment of special second order ordinary differential equations: general and exponentially fitted methods
(Universita degli studi di Salerno, 2012-04-19)The aim of this research is the construction and the analysis of new families of numerical methods for the integration of special second order Ordinary Differential Equations (ODEs). The modeling of continuous time ... -
Dissipation, mixing and two level system in quantum field theory
(Universita degli studi di Salerno, 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 ... -
Logit dynamics for strategic games mixing time and metastability
(Universita degli studi di Salerno, 2012-04-18)A complex system is generally de_ned as a system emerging from the interaction of several and di_erent components, each one with their properties and their goals, usually subject to external inuences. Nowadays, complex ... -
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 ... -
Analysis of a birth and death process with alternating rates and of a telegraph process with underlying random walk
(Universita degli studi di Salerno, 2012-04-24)My thesis for the Doctoral Programme in Mathematics (November 1, 2008 - October 31, 2011) at University of Salerno, Italy, has been oriented to the analysis of two stochastic models, with particular emphasis on the ... -
On the solvability of linear PDEs in weighted Sobolev spaces
(Universita degli studi di Salerno, 2012-03-30)In this work we are interested in strong solutions of a Dirichlet problem for an elliptic linear operator... [edited by author] -
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, ... -
Highly Stable Multistage Numerical Methods for Functional Equations: Theory and Implementation Issues
(Universita degli studi di Salerno, 2010-08-06)Functional equations provide the best and most natural way to describe evolution in time and space, also in presence of memory. In fact, the spread of diseases, the growth of biological populations, the brain dynamics, ... -
