We propose a new hybrid I/O automaton model that is capable of describing both continuous and discrete behavior. The model, which extends the timed I/O automaton model of 12, 7] and the phase transition system models of 15, 2], allows communication among components using both shared variables and shared actions. The main contributions of this paper are: (1) the deenition of hybrid I/O automata ...

A hybrid particle scheme is presented for the simulation of compressible gas flows involving both continuum regions and rarefied regions with strong translational nonequilibrium. The direct simulation Monte Carlo (DSMC) method is applied in rarefied regions, while remaining portions of the flowfield are simulated using a DSMC-based low diffusion particle method for inviscid flow simulation. The...

A hybrid particle scheme, which is based on the direct simulation Monte Carlo (DSMC) method and incorporates a low diffusion particle method for continuum flow simulation, is extended for improved efficiency and wider applicability. The hybrid scheme is intended for simulation of gas flows involving a wide range of Knudsen number regimes, where strong coupling is desired between calculations in...

This paper addresses a central concern in modeling and simulating electric grids and the information infrastructure that monitors and controls them. As the electric power infrastructure incorporates modern computing and communication technology, joint (hybrid) simulations of continuous power system models and discrete event models of communication, computation, and control operations become ess...

Hardware-in-the-Loop (HiL) simulation is known as a reliable approach for testing and verification of the control system of hybrid vehicles.
