Exact solutions in general relativity and alternative theories of gravity: mathematical and physical properties
(2011-06-06)
In this thesis, we discuss several subjects connected with the framework
of GR, in order to characterize astrophysical compact objects. The main
purpose is to provide simple models describing gravitational fields generated ...
Polymorphism and co-crystalline phases of polymers
(2012-02-04)
Crystalline phases are extremely relevant for properties and applications of many polymeric
materials. In fact, their amount, structure and morphology constitute the main factors controlling
physical properties of fibers, ...
Investigation of the groundwater-river interaction, using Radon-222 as a natural tracer, in a karst Mediterranean environment like in the case study of the Bussento river basin
(2010-04-27)
The naturally-occurring radionuclides have proven to be powerful tools for assessing the time dependency of GSI processes. The radionuclide 222Rn (referred to as radon) has the advantage of being a radioactive noble gas, ...
A molecular dymanics view of structure and reactivity
(2011-02-21)
The eld of computer simulations has developed into a very important branch of science providing a guess at
the interactions between molecules to obtain predictions of properties as accurate as required, subject to ...
Simulation and optimization of supply chains and networks using a macroscopic approach
(2011-03-16)
The aim of thesis is to present some macroscopic models for supply chains
and networks able to reproduce the goods dynamics, successively to show, via
simulations, some phenomena appearing in planning and managing such ...
Forensic Analysis for Digital Images
(2011-11-23)
Nowadays, taking and sharing digital pictures is becoming a very popular
activity. This is witnessed by the explosive growth of the digital cameras
market: e.g., more than one billion of digital cameras have been produced
and ...
Magneto-transport properties of thin superconducting strips in the framework of Time Dependent Ginzburg Landau model
(2012-05-30)
This dissertation is addressed to summarize my experimental/phenomenological research
activities conducted at the laboratories of Physics Department, University of Salerno. The
experimental work consisted in the fabrication ...
Discovering hidden structures in high dimensional data space
(2011-03-01)
Il grande volume di dati che viene attualmente collezionato nei vari campi di applicazione non può essere gestito usando le tecniche standard di data mining.
L’obiettivo principale del presente lavoro di tesi è quello di ...
Synthesis,characterization and catalytic activity of organometallic complexes of group 3 and 4 with N-heterocyclic carbene ligands
(2011-02-21)
The synthesis and characterization of a zirconium complex, having two alkoxide funtionalized N-heterocyclic carbene ligands, and its behaviour as catalyst in the polymerization of ethylene and propylene, have been reported.
NMR ...
Numerical treatment of special second order ordinary differential equations: general and exponentially fitted methods
(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 dynamical ...
