(Universita degli studi di Salerno, 2023-05-16)In the last twenty years the school has been hit by a succession of disruptive and unknown innovations. In particular, there is institutional talk for the first time of ascertaining competences in DPR 323-98 (reform of ... -
Orbital motion, periastron advance and galaxy rotation curves beyond General Relativity
(Universita degli studi di Salerno, 2023-01-02)The Extended Theories of Gravity (ETG) have become one of the most investigated the- oretical proposals among the alternative explanations for the observed flatness of galaxy rotation curves, related to the dark matter ... -
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 ... -

Praseodymium and manganese doped Ca2RuO4: crystals growth and physical properties
(Universita degli studi di Salerno, 2023-07-17)Layered ruthenates have received a great attention in condensed matter physics due to the richness of their physical properties and the related phase diagram. Ruthenate compounds show a strong interplay between electronic, ... -
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 ... -
Λ + c production vs the event charged-particle multiplicity in pp collisions at 13 TeV with ALICE at the LHC
(Universita degli studi di Salerno, 2023-03-22)The Quantum Chromo-Dynamics (QCD) theory predicts, in condition of very high temperature and/or energy density, a phase transition from the ordinary nuclear matter to a colour-deconfined medium called Quark–Gluon Plasma ... -
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, ... -
Ambient seismic noise to image and monitor the propagation medium elastic properties in georesource exploration and exploitation areas
(Universita degli studi di Salerno, 2021-11-10)Traditional seismological methods for the study of the Earth structure are based on the information that can be extracted from direct waves emitted by seismic sources such as earthquakes or explosions. Useful information ... -
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 ... -
Properties and applications of pdf-related information measures and distributions
(Universita degli studi di Salerno, 2021-06-14)The study of the information measures gives rise to different measures according to the contests in which it is applied. In the contest of reliability theory and survival analysis, an ever-growing interest is given by the ... -
Polyhedral analysis and branch and cut algorithms for some NP-hard spanning subgraph problems
(Universita degli studi di Salerno, 2020-01-07)There is a widespread need to use a quantitative approach for the solution of decision problems that arise in many different areas of real life. The goal is to choose which decisions to take to manage a real system as ... -
A game theoretical approach to safe decision making system development for autonomous machines
(Universita degli studi di Salerno, 2021-03-20)One of the major technological and scientific challenges in developing autonomous machines and robots is to ensure their ethical and safe behavior towards human beings. When dealing with autonomous machines the human ... -
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 ... -
Exploring the transport properties of quantum systems on different lenght scales
