Sliding lubricated anisotropic rough surfaces [PDF]

, 2001
The object of this paper is to study the effects of lubricant film flow, pressurized and sheared between two parallel rough surfaces in sliding motion. The influence of microscopic surface roughness on lubricant film flow macroscopic behavior is described ...

Particle interactions mediated by dynamical networks: assessment of macroscopic descriptions [PDF]

, 2017
We provide a numerical study of the macroscopic model of [3] derived from an agent-based model for a system of particles interacting through a dynamical network of links.

Basic concepts and models in continuum damage mechanics [PDF]

, 2007
In this paper, we present some basic elements of macroscopic modelling of damage. We then recall the general approach of continuum damage based on the thermodynamics of irreversible processes and its application to isotropic damage modelling.

Testing microscopic discretization [PDF]

, 2013
What can we say about the spectra of a collection of microscopic variables when only their coarse-grained sums are experimentally accessible? In this paper, using the tools and methodology from the study of quantum nonlocality, we develop a mathematical ...

Study of nonlocal correlations in macroscopic measurement scenario

, 2017
Nonlocality is one of the main characteristic features of quantum systems involving more than one spatially separated subsystems. It is manifested theoretically as well as experimentally through violation of some local realistic inequality.

A numerical closure approach for kinetic models of polymeric fluids: exploring closure relations for FENE dumbbells

, 2010
We propose a numerical procedure to study closure approximations for FENE dumbbells in terms of chosen macroscopic state variables, enabling to test straightforwardly which macroscopic state variables should be included to build good closures. The method

Macroscopic chaos in globally coupled maps

, 1998
We study the coherent dynamics of globally coupled maps showing macroscopic chaos. With this term we indicate the hydrodynamical-like irregular behaviour of some global observables, with typical times much longer than the times related to the evolution ...

Creation of macroscopic superposition states from arrays of Bose-Einstein condensates [PDF]

, 2006
We consider how macroscopic quantum superpositions may be created from arrays of Bose-Einstein condensates. We study a system of three condensates in Fock states, all with the same number of atoms and show that this has the form of a highly entangled ...

Universal macroscopic background formation in surface super-roughening

, 1998
We study a class of super-rough growth models whose structure factor satisfies the Family-Vicsek scaling. We demonstrate that a macroscopic background spontaneously develops in the local surface profile, which dominates the scaling of the local surface ...

Homogenization in magnetic-shape-memory polymer composites

, 2017
Magnetic-shape-memory materials (e.g. specific NiMnGa alloys) react with a large change of shape to the presence of an external magnetic field. As an alternative for the difficult to manifacture single crystal of these alloys we study composite materials
