Non-markovian quantum dynamics
(Universita degli studi di Salerno, 2016-04-28)Quantum systems can necessarily be viewed as open systems. As in classical physics, any realistic description of a system must take into account the cou- pling to an environment that strongly in uences the system itself. ... -
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 ... -
Novel macrocyclic systems in asymmetric phase-transfer catalysis
(Universita degli studi di Salerno, 2017-02-27)In the great realm of organic synthesis, phase-transfer catalysis (PTC) is a well recognized methodology which plays a key role both in industry and academia research. This process involves reactions that take place between ... -
Novel technologies and process intensification in the production of micro-systems with pharmacological/nutraceutical activity
(Universita degli studi di Salerno, 2015-04-22)Purpose of the PhD thesis was to develop a novel microencapsulation process, designing and building a single-pot semi-continuous bench scale apparatus. The novel process is based on the coupling of two emerging techniques, ... -
Numerical treatment of special second order ordinary differential equations: general and exponentially fitted methods
(Universita degli studi di Salerno, 2012-04-19)The aim of this research is the construction and the analysis of new families of numerical methods for the integration of special second order Ordinary Differential Equations (ODEs). The modeling of continuous time ... -
Old and new problems in continuum structural materials
(Universita degli studi di Salerno, 2014-05-17)The PhD thesis in Mathematics titled "Old and New Problems in continuum structural masterials " is divided into two parts. In Part I ( Chapter I and II relative to the " Old Problems" ) is studied in particular the classic ... -
Olefin Metathesis Reactions Promoted by Ru-Catalysts with a Syn Substituted N-heterocyclic Carbene Backbone
(Universita degli studi di Salerno, 2014-03-06)The development of efficient catalytic systems dedicated to the formation of C−C double bonds from simple to highly functionalized alkenes represents a great challenge in modern organic synthesis. In addressing this ... -
Olive oil and oleate affect hepatic proteome and mitochondrial dynamics: in vivo and in vitro approaches
(Universita degli studi di Salerno, 2021-05-27)The Mediterranean diet (MD) has been pointed out as a nutritional approach to prevent metabolic disturbances leading to obesity, diabetes and liver steatosis. These properties have been largely attributed to oleic acid and ... -
On fractional probabilistic mean value theorems, fractional counting processes and related results
(Universita degli studi di Salerno, 2017-07-17)The thesis collects the outcomes of the author’s research carried out in the research group Probability Theory and Mathematical Statistics at the Department of Mathematics, University of Salerno, during the doctoral programme ... -
On neutrino mixing in Quantum Field Theory
(Universita degli studi di Salerno, 2017-05-23)Neutrino physics is one of the most important areas in research on the fundamental interactions, both theoretically and experimentally. A central issue in the study of these particles is related to the properties of mixing ... -
On the evolution of digital evidence: novel approaches for cyber investigation
(Universita degli studi di Salerno, 2014-04-23)Nowadays Internet is the fulcrum of our world, and the World Wide Web is the key to access it. We develop relationships on social networks and entrust sensitive documents to online services. Desktop applications are being ... -
On the formulation of Einstein general relativity in a phisycal reference system
(Universita degli studi di Salerno, 2012-04-06)The research deals with the breaking of the evolution problem of a reversible material system in two different problems, the initial data problem and the restricted evolution problem. This breaking, intrinsically formulated, ... -
On the Generalizations of Identity-Based Encryption
(Universita degli studi di Salerno, 2013-04-16)Today public-key cryptographic is widely deployed and successfully used but still a major drawback exists. In fact, from encrypted data a party can either decrypt or cannot learn anything at all about the message other ... -
On the solvability of linear PDEs in weighted Sobolev spaces
(Universita degli studi di Salerno, 2012-03-30)In this work we are interested in strong solutions of a Dirichlet problem for an elliptic linear operator... [edited by author] -
On the verification of parametric and real-time systems
(Universita degli studi di Salerno, 2011-05-06)Parametric and Real-Time Systems play a central role in the theory underlying the Verification and Synthesis problems. Real-time systems are present everywhere and are used in safety critical applications, such as flight ... -
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 ... -
