Anomalous behaviour of hydrodynamic modes in the two dimensional shear flow of a granular material
Kumaran, V. - In: Physica A: Statistical Mechanics and its Applications 284 (2000) 1, pp. 246-264
The growth rates of the hydrodynamic modes in the homogeneous sheared state of a granular material are determined by solving the Boltzmann equation. The steady velocity distribution is considered to be the product of the Maxwell–Boltzmann distribution and a Hermite polynomial expansion in the...

TRANSIENT AND STEADY-STATE DYNAMICS OF GRANULAR SHEAR FLOWS
LOSERT, W.; KWON, G. - In: Advances in Complex Systems (ACS) 04 (2001) 04, pp. 369-377
The initiation and steady-state dynamics of granular shear flow are investigated experimentally in a Couette geometry with independently moveable outer and inner cylinders. The motion of particles on the top surface is analyzed using fast imaging. During steady state rotation of both cylinders...

Structure of a tethered polymer under flow using molecular dynamics and hybrid molecular-continuum simulations

At large shear … rates the polymer becomes more elongated than predicted by existing theoretical scaling laws. Also, along the normal-to-wall …. Comparison with previous Brownian dynamics simulations (which exclude both solvent and wall potential) indicates that these …

Driven steady states: rules for transition rates
Evans, R.M.L. - In: Physica A: Statistical Mechanics and its Applications 340 (2004) 1, pp. 364-372
It is well known that transition rates in a canonical ensemble should respect the principle of detailed balance. What are the equivalent constraints that apply in non-equilibrium steady states, implied by maximization of information-entropy? The exact theorem for the non-equilibrium rates yields...

The dynamic inelastic response of delaminated plates
Addessio, F.L.; Williams, T.O. - 2009
A generalized theory for laminated plates with delaminations is used to consider the influence of inelastic deformations on the dynamic behavior of composite plates with delaminations. The laminate model is based on a generalized displacement formulation implemented at the layer level. The...

Mind the gap!: Stylized dynamic facts and structural models
Canova, Fabio; Ferroni, Filippo - 2019
We study what happens to identified shocks and to dynamic responses when the data generating process features q disturbances but less than q variables are used in the empirical model. Identified shocks are mongrels: they are linear combinations of current and past values of all structural...

A parametric registration model for warped distributions with Wasserstein’s distance
Agulló-Antolín, Marina; Cuesta-Albertos, J.A.; … - In: Journal of Multivariate Analysis 135 (2015) C, pp. 117-130
We consider a parametric deformation model for distributions. More precisely, we assume we observe J samples of random … individual deformation parameters. For this, we construct a registering criterion based on the Wasserstein distance to quantify …
