Modelling, Simulation and Dynamic Sliding Mode Control of a MEMS Gyroscope
Micromachines, 2021 An adaptive dynamic sliding mode control via a backstepping approach for a microelectro mechanical system (MEMS) vibratory z-axis gyroscope is presented in this paper. The time derivative of the control input of the dynamic sliding mode controller (DSMC)

On the velocity distributions of the one-dimensional inelastic gas [PDF]
, 2001 We consider the single-particle velocity distribution of a one-dimensional fluid of inelastic particles. Both the freely evolving (cooling) system and the non-equilibrium stationary state obtained in the presence of random forcing are investigated, and ...

Transport properties of highly asymmetric hard-sphere mixtures [PDF]
, 2009 The static and dynamic properties of binary mixtures of hard spheres with a diameter ratio of sigma(B)/sigma(A)= 0.1 and a mass ratio of m(B)/m(A)= 0.001 are investigated using event driven molecular dynamics.

Direct Simulation Monte Carlo for astrophysical flows: II. Ram pressure dynamics [PDF]
, 2013 We use the Direct Simulation Monte Carlo (DSMC) method combined with an n-body code to study the dynamics of the interaction between a gas-rich spiral galaxy and intracluster or intragroup medium, often known as the ram pressure scenario.

A New Parallel Algorithm of DSMC Method
Procedia Engineering, 2015 AbstractA new parallel algorithm of DSMC method with dynamic load balance implementation was introduced using MPI standard library. The parallel efficiency of the two kinds of parallel modes, peer-to-peer mode and master/slave mode, were investigated, respectively.

Simulating fluid flows in micro and nano devices : the challenge of non-equilibrium behaviour [PDF]
, 2009 We review some recent developments in the modelling of non-equilibrium (rarefied) gas flows at the micro- and nano-scale, concentrating on two different but promising approaches: extended hydrodynamic models, and lattice Boltzmann methods.
