Discrete fully probabilistic design: towards a control pipeline for the synthesis of policies from examples
Enrico Ferrentino, Pasquale Chiacchio, Giovanni Russo
We present the principled design of a control pipeline for the synthesis of policies from examples data. The pipeline, based on a discretized design which we term as discrete fully…
A meshfree arbitrary Lagrangian-Eulerian method for the BGK model of the Boltzmann equation with moving boundaries
Sudarshan Tiwari, Axel Klar, Giovanni Russo
In this paper we present a novel technique for the simulation of moving boundaries and moving rigid bodies immersed in a rarefied gas using an Eulerian-Lagrangian formulation based…
Modeling and simulations of moving droplet in a Rarefied gas
S. Tiwari, A. Klar, G. Russo
We study a two phase flow with interactions of liquid and rarefied gas inside the gas phase. The gas phase is modeled by the BGK model of the Boltzmann equation. The liquid phase i…
Spectral and norm estimates for matrix sequences arising from a finite difference approximation of elliptic operators
Armando Coco, Sven-Erik Ekström, Giovanni Russo +2
When approximating elliptic problems by using specialized approximation techniques, we obtain large structured matrices whose analysis provides information on the stability of the…
A local velocity grid conservative semi-Lagrangian schemes for BGK model
Sebastiano Boscarino, Seung Yeon Cho, Giovanni Russo
Most numerical schemes proposed for solving BGK models for rarefied gas dynamics are based on the discrete velocity approximation. Since such approach uses fixed velocity grids, on…
High Order Semi-implicit WENO Schemes for All Mach Full Euler System of Gas Dynamics
Sebastiano Boscarino, Jing-Mei Qiu, Giovanni Russo +1
In this paper, we propose a new high order semi-implicit scheme for the all Mach full Euler equations of gas dynamics. Material waves are treated explicitly, while acoustic waves a…
