Exact solutions in general relativity and alternative theories of gravity: mathematical and physical properties
(Universita degli studi di Salerno, 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 ... -
The neutrino interaction analysis chain in OPERA
(Universita degli studi di Salerno, 2011-04-20)The aim of the OPERA experiment is to provide a “smoking-gun” proof of neutrino oscillations, through the detection of the appearance signal of ντ’s in an initially pure νμ beam. The beam is produced at CERN, 732 Km far ... -
Magnetic orbital and transport properties in LaMnO3 based based heterostructures
(Universita degli studi di Salerno, 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 ... -
Multiscale wavelet analysis for integral and differential problems
(Universita degli studi di Salerno, 2011-03-08)The object of the present research is wavelet analysis of integral and differential problems by means of harmonic and circular wavelets. It is shown that circular wavelets constitute a complete basis for L2[0; 1] functions, ... -
Improvements in the acoustical modelling of traffic noise prediction: theoretical and experimental results
(Universita degli studi di Salerno, 2011-04-21)Traffic acoustical noise is one of the most important component of the urban environmental pollution in densely populated areas all over the world. A very recent ACI-Censis study [1] on Italian urban areas shows that car ... -
Some topics in the theory of generalized fc-groups
(Universita degli studi di Salerno, 2011-02-15)A finiteness condition is a group-theoretical property which is possessed by all finite groups: thus it is a generalization of finiteness. This embraces an immensely wide collection of properties like, for example, ... -
Lukasiewicz logic: algebras and sheaves
(Universita degli studi di Salerno, 2011-02-21)Classical logic arose from the need to study forms and laws of the human reasoning. But soon, it came out the di culties of classical logic to formalize uncertain events and vague concepts, for which it is not possible ... -
Simulation and optimization of supply chains and networks using a macroscopic approach
(Universita degli studi di Salerno, 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 ... -
Uniqueness and partition of energy for thermomicrostretch elastic solids backward intime
(Universita degli studi di Salerno, 2011-06-12)In questo lavoro, è mostrata l’unicità delle soluzioni per il problema a ritroso nel tempo della teoria lineare dei materiali elastici termomicrostretch, ed è provata l’impossibilità della localizzazione nel tempo della ... -
Discovering hidden structures in high
(Universita degli studi di Salerno, 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 ... -
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
(Universita degli studi di Salerno, 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, ... -
Some topics in fuzzy logic
(Universita degli studi di Salerno, 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 ... -
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, ...
