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 ... -
Behavioral Biometrics in the Era of Artificial Intelligence
(Universita degli studi di Salerno, 2023-02-22)Biometric technologies have historically been explored as Pattern Recognition systems. Over the past three decades, biometric- based human recognition systems have significantly changed and improved. Applications ... -

Estimates for the transition kernel for elliptic operators with unbounded coefficients
(Universita degli studi di Salerno, 2023-02-09)This manuscript is devoted to the study of the qualitative behaviour of the solutions of evolution equations arising from elliptic and parabolic problems on unbounded domains with unbounded coefficients. In particular, ... -
A characterisation of mathematics education creativity inspired by active and popular pedagogy
(Universita degli studi di Salerno, 2023-05-30)The present PhD thesis has been developed through an interweaving of reflections and experiences in the field of mathematics education that have, gradually, steered the research interest in a specific direction. Initially, ... -
On the regularity of solutions of free boundary problems
(Universita degli studi di Salerno, 2023-02-09)Optimal design problems have aroused particular interest in the scientific com- munity over the past thirty years. In physics, for example, they find application in the investigation of the minimal energy configurations ... -
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 ... -
A Study of some ML and DL-based Strategies for Network Security
(Universita degli studi di Salerno, 2023-06-26)The Internet and advanced communication networks, such as IoT and cellular net- works, produce enormous and diverse traffic data flows. The behavior of network traffic in these networks is highly intricate due to factors ... -
Isolation and characterization of lignins from Wheat straw and cardoon biomasses
