Physical Layer Authentication With Channel Knowledge Maps in Indoor Environments

Luca Bonaventura, Francesco Ardizzon, Stefano Tomasin

Physical layer authentication (PLA) allows to authenticate the user by comparing measurements over time, assuming their time consistency or by modeling their evolution. However, th…

An IMEX-DG solver with non-conforming mesh refinement for atmospheric dynamics with rotation

Letizia Bottani, Tommaso Benacchio, Giuseppe Orlando +2

We present a high-order implicit-explicit discontinuous Galerkin (IMEX-DG) solver for the compressible Euler equations to account for rotational effects within a fully compressible…

Impact of curved elements for flows over orography with a Discontinuous Galerkin scheme

Giuseppe Orlando, Tommaso Benacchio, Luca Bonaventura

We present a quantitative assessment of the impact of high-order mappings on the simulation of flows over complex orography. Curved boundaries were not used in early numerical meth…

Asymptotic-preserving IMEX schemes for the Euler equations of non-ideal gases

Giuseppe Orlando, Luca Bonaventura

We analyze schemes based on a general Implicit-Explicit (IMEX) time discretization for the compressible Euler equations of gas dynamics, showing that they are asymptotic-preserving…

A comparison of different approaches to compute surface tension contribution in incompressible two-phase flows

Giuseppe Orlando, Paolo Francesco Barbante, Luca Bonaventura

We perform a quantitative assessment of different strategies to compute the contribution due to surface tension in incompressible two-phase flows using a conservative level set (CL…
