A model of nonlocal heat transfer at nanoscale in rigid bodies will be considered. Depending on the relevance of the particular interaction's mechanism between the heat carriers and the lateral walls, three different strategies for the setting of the boundary conditions will be analyzed, and the consequent forms of the basic fields have been obtained, as well. From the physical point of view, the

We studied thermal waves along nanowires to include the effects both of the surfaces and of nonlinearities. However, it could be useful to explore the effects of the heat boundary conditions in smooth- and rough-walled nanowires, as well as to consider the unsteady state characterized by a frequency-dependent temperature gradient. It will be also interesting to analyze whether Second Law is capabl

Motivated by recent developments regarding nonlocal integral functionals, as well as new models in machine learning, I want to address related questions by discussing homogeneous L^\infty-functionals inthe nonlocal setting. I want to show that weak* lower semicontinuity holds if and onlyif certain conditions are satisfied by the supremand (density of the L^\infty functional). I also expect that

Grazie alla recente Teoria delle Deformazioni Strutturate (che si è recentemente sviluppata sia dal punto di vista della Meccanica del Continuo sia da quello del Calcolo delle Variazioni) ci si propone di ottenere un'analisi multiscala di materiali complessi, quali policristalli e materiali multifase, che catturi sia i contributi macroscopici dei cambiamenti geometrici regolari o meno, sia a livel

Functionally graded materials (FGMs) are composite materials with an inhomogeneous micromechanical structure. They are generally made of two components and, in contrast to traditional composites, are characterized by a compositional gradient from one component to the other.In the special case of heat-wave propagation in 3D FGMs we aim to study, in the framework of this project, the role played by
