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 ... -
Detailed study of the 2010-2014 Pollino (Italy) seismic sequence with absorption and scattering imaging of the surrounding area
(Universita degli studi di Salerno, 2020-02-04)A detailed study of the seismic sequence occurred in the western sector of the Pollino Range (Southern Italy) between 2010 and 2014, and an imaging of the surrounding area, have been performed in this thesis. The sequence, ... -
Development of an adaptive hierarchical multi-scale approach for the assessment, planning and prevention of the impact on anthropic and natural environments due to the exceeding of radon gas concentrations above threshold values and the corresponding risk associated to indoor radon exposures
(Universita degli studi di Salerno, 2018-04-17)Human exposure to natural Naturally Occurring Ionizing Radiation (NOIR), as that one related to Radon and its progeny, has been established as harmful by the worldwide scientific community and acknowledged by many international ... -
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 ... -
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 ... -
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 ... -
Exploring the transport properties of quantum systems on different lenght scales
(Universita degli studi di Salerno, 2021-11-10)In this thesis, after introducing some theoretical aspects of Mott insulators, pure single crystals of the Mott insulator Ca2RuO4 was investigated from an experimental point of view. The surprisingly low current density ... -
Gravitational lensing by massive and Exotic objects
(Universita degli studi di Salerno, 2023-02-21)Space-time is curved by the presence of massive bodies and this curvature influences the motion of the bodies themselves: this leads to a geometry in constant evolution. One of the consequences is that even light, supposed ... -
Hidden Structures and Conflicting Items in Combinatorial Optimization Problems
(Universita degli studi di Salerno, 2023-02-14)Combinatorial optimization-based methods are widely used to solve complex real life problems. In this thesis, we use some of these methods for addressing several emerging combinatorial opti- mization problems on graphs ... -
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 are ... -
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 ... -
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 ... -
Methodologies for environmental risks assessment related to the exploitation of energy geo-resources
(Universita degli studi di Salerno, 2021-10-05)The increasing exploitation of geo-energy resources to satisfy the needs of the world's population has also led to a focus on the risks associated with this type of human activity. It is in this context that this thesis ... -
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 ... -
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 ... -
Noncoercive nonlinear elliptic equations in unbounded domains
(Universita degli studi di Salerno, 2020-01-02)This research thesis is mainly devoted to the study of noncoercive Dirich let problems with discontinuous coefficients in unbounded domains. The presence of the noncoercive operator does not allow us to use classical the ... -
Nonlocal and nonlinear transport theories at nanoscale: applications to wave propagation
(Universita degli studi di Salerno, 2021-04-23)Many books and/or papers have been published on linear generalizations of Fourier's equation in order to introduce relaxational and nonlocal e ects for the heat ux [1{9]. Describing a heat-pulse propagation with a nite ... -
Numerical Modeling of Stochastic Differential Problems with Applications
(Universita degli studi di Salerno, 2023-01-27)The interest in the study of stochastic differential equations has grown considerably in recent years. The main reason for this interest is that stochastic differential equations are a potential tool for modeling evolutionary ... -
