Conflicting edges spanning trees and NP-Hard subgraph identification problems
(Universita degli studi di Salerno, 2018-04-17)How often do we try to get the best result with the least effort, spend as little time as possible to perform a task or make the most of the resources available in the workplace? In everyday life, the word ”optimize” is ... -
Aspetti fisico-matematici dei Materiali Auxetici con Memoria di Forma
(Universita degli studi di Salerno, 2018-04-09)The Poisson coefficient, or Poisson’s Ratio, plays a fundamental role in the Continuum Mechanics theory, which represents the relationship between lateral contraction and longitudinal elongation of a material subjected ... -
Event triggering and deep learning for particle identification in KM3NeT
(Universita degli studi di Salerno, 2018-04-11)Neutrino astronomy experiments like KM3NeT allow to survey the Universe leveraging the properties of neutrinos of being electrically neutral and weakly interacting particles, making them a suitable messenger. Observing ... -
On Vector-Valued Schrodinger Operators in Lp-spaces
(Universita degli studi di Salerno, 2018-04-06)... We construct a realization Ap of A in the spaces Lp(Rd;Cm), 1 p < 1, that generates a contractive strongly continuous semigroup. First, by using form methods, we obtain generation of holomorphic semigroups when the ... -
Electrical and thermal transport properties of superconducting materials relevant for applications
(Universita degli studi di Salerno, 2018-07-06)Superconducting materials are used in several applications among which the large-scale ones take advantage of the high energy transport capabilities of superconductors due to the low losses in electrical conduction. From ... -
Lo pseudotensore energia-impulso in teorie estese della gravitazione
(Universita degli studi di Salerno, 2018-07-12)The gravitational field’s energy and momentum definitions are treated in extensive gravitation theories, through the generalization of the energymomentum pseudotensor, defined by Einstein in general relativity. This ... -
Electical properties of pure and Co-substituted ZnO thin films investigated by UV-assisted SPM experiments
(Universita degli studi di Salerno, 2018-06-28)ZnO is an intrinsic n-type, wide band-gap (3.4 eV at 0 K), semiconductor which has been attracted the interest of the scientific community for several decades. More recently, ZnO has caught a renewed interest due to the ... -
Low-frequency noise spectroscopy as an effective tool for electric transport analysis
(Universita degli studi di Salerno, 2018-07-09)In this work, several experiments and analyses performed by means of noise spectroscopy, on a broad typology of materials and compounds, are presented. Structural, DC electrical transport and noise properties are exposed ... -
Unveiling spin-orbit coupling e ects on the electronic states of multi-orbital Transition Metal Oxides
(Universita degli studi di Salerno, 2018-06-03)Transition Metal Oxides (TMOs) show a wealth of intriguing properties which are governed by the interplay of charge, spin, and orbital degrees of freedom. Moreover, the comprehension of the features of strongly ... -
Low and high field Magnetic Resonance Imaging and its application in food science and plants
(Universita degli studi di Salerno, 2018-11-20)Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) are techniques that have seen a remarkable success and a fast growth over the past decades. Thanks to its non-invasivity and non-descrutivity, the MRI ... -
Stochastic processes governed by the generalized telegraph process and by Brownian motion and their applications
(Universita degli studi di Salerno, 2021-06-18)The aim of this research thesis is to broaden the treatment of stochastic processes derived from the telegraph process and Brownian motion. First, the classical telegraph process is presented. The Kolmogorov equations ... -
MV-algebras, semirings and their applications
(Universita degli studi di Salerno, 2021-04-17)The thesis is divided in two parts: the first part regards MV-semirings, involutive semirings and semimodules over them with particular attention to injective and projective semimodules; the second part of the thesis is ... -
Tailoring the structural and surface properties of TiO2 thin films and TiO2-based nanolayers, with heat treatments, layer thickness, and oxide mixtures
(Universita degli studi di Salerno, 2021-12-15)Titanium dioxide (TiO2), also known as titanium (IV) oxide or titania, is naturally available on the Earth as a bright, fine, and white pigment. Thanks to its unique properties, such as high refractive index, chemical ... -
New features exhibited by transition metal pnictides
(Universita degli studi di Salerno, 2020-02-05)Superconductivity under pressure was recently discovered in two transition metal pnictides belonging to the Pnma space group, namely CrAs [1, 2] and MnP [3], in the vicinity of a magnetic phase, respectively at the ... -
Local and global properties of Jacobi related geometries
(Universita degli studi di Salerno, 2019-12-18)In this thesis local and global properties of Jacobi and related geometries are discussed, which means for us that so-called Dirac-Jacobi bundles are considered. The whole work is roughly divided in three parts, which ... -
