Mechanisms of De‐icing by Surface Rayleigh and Plate Lamb Acoustic Waves
Advanced Engineering Materials, EarlyView.Ice accretion impacts daily life, renewable energy generation, maintenance, and security in industries and aeronautics. Acoustic waves (AW) are a promising method for ice removal, although de‐icing mechanisms require further investigation to optimize energy efficiency.

Time discretization of the spin Calogero-Moser model and the semi-discrete matrix KP hierarchy [PDF]
, 2018 We introduce the discrete time version of the spin Calogero-Moser system. The equations of motion follow from the dynamics of poles of rational solutions to the matrix KP hierarchy with discrete time. The dynamics of poles is derived using the auxiliary linear problem for the discrete flow.

GROUPOIDS AND IRREVERSIBLE DISCRETE DYNAMICAL SYSTEMS II [PDF]
Fiabilitate şi Durabilitate, 2012 The purpose of this paper is to study the topology of the orbit space of an irreversible discrete dynamical system (X, ) seen as a principal groupoid associated to the groupoid G(X,,E) introduced in [1] (where E is an equivalence relation on X).

Dynamical properties of spatial discretizations of a generic homeomorphism [PDF]
Ergod. Th. Dynam. Sys. 35 (2014) 1474-1523, 2012 This paper concerns the link between the dynamical behaviour of a dynamical system and the dynamical behaviour of its numerical simulations. Here, we model numerical truncation as a spatial discretization of the system. Some previous works on well chosen examples show that the dynamical behaviours of dynamical systems and of their discretizations can ...

Discrete and continuous dynamical systems
Computers & Mathematics with Applications, 1996 AbstractA basic process is the observation of an N-dimensional quantity x(t) in discrete time steps a + jh where j runs through the natural numbers. Naturally, one looks for the rate of change of this ‘information’ during one time step. We show that we obtain a discrete evolution equation which turns up in many fields of numerical analysis: Newton's ...
