Since their discovery, graphene and carbon nanotubes have been playing an important role in nanoscience and nanotechnology thanks to their extraordinary physical and chemical properties. With silicon-based electronics ...

This thesis, as the research activity of the author, is devoted to establish new connections and to strengthen well-established relations between different branches of mathematics, via logic tools. Two main many valued ...

La TPMC risulta essere una procedura molto più sofisticata perché lavora in perfetto accordo con le raccomandazioni dei codici normativi visto che rispetta a pieno i criteri di gerarchia. Questi ultimi, infatti, sono fondamentali ...

Questa tesi è parte di una ricerca che mira a comprendere se sia possibile utilizzare, nell'ambito dell'educazione matematica, una piattaforma di e-learning per realizzare un insegnamento basato sulla mediazione e ...

My doctoral thesis concerns research in mathematics education, with particular reference to the use of the social networks. In this respect, I am interested in online discussion in mathematics and the comparison between ...

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 ...

The actual surveys highlight that teaching scientific disciplines it gives often-inadequate results, in Italy particularly, and it emerges that, in general, the educational aspects of the teaching of the Physics are not ...

In the “standard” Gizburg-Landau approach, a phase transition is intimately connected to a local order parameter, that spontaneously breaks some symmetries. In addition to the “traditional” symmetry-breaking ordered phases, ...

This work is focused on two helimagnetic materials: Ba2CuGe2O7 and Cu3Nb2O8. Recent studies report a number of interesting anisotropic proper- ties [1, 2, 3]. Ba2CuGe2O7 melilite oxide shows a complex magnetic behaviour, ...

The topic of my PhD thesis is a seismic tomography which has as object of investigation Italy, particularly Southern Italy and Southern Tyrrhenian. This tomography has been obtained by means of inversion of teleseismic ...
