equipartition

[¦e·kwə·pär′tish·ən]

The equal distribution of a compound between two solvents.
The distribution of the atoms in an orderly fashion, such as in a crystal.

Mathematically speaking equipartition based kinetic theory states that a molecule with n" atoms has 3n" degrees of freedom (f) [5-6] i.
With consideration for the eigenfunctions of 1-D structure, these results exhibit equipartition of kinetic energy between Love and Rayleigh waves.
Eddington, in his book Stellar Movements and the Structure of the Universe, (1914) was obviously taken by the Maxwellian idea but showed that the stars could not interact sufficiently to lead to equipartition of energy and that, therefore, Halm's theory was incorrect.
Our separation result for the multiparty communication complexity hierarchy holds in the strongest possible sense: our lower bound holds for every equipartition (even the best), and our upper bound holds for every partition (even the worst).
The researchers showed for the first time how photospheric plasma motion and magnetic fields are in equipartition over a wide dynamic range, while unleashing energy in ever-smaller scales.
Since, by application of the equipartition theorem of classical statistical mechanics, the total energy of the gas is E = [N.
The large number of internal atomic degrees of freedom that spectroscopy required seemed incompatible with the equipartition of energy.
The effect of an information source of external signals Y, is now seen in terms of more complex joint paths in Y and the R-space (of operators) whose behavior is, again, governed by a mutual information splitting criterion according to the Joint Asymptotic Equipartition Theorem (a variant of the Shannon-McMillan Theorem).
This definition is sometimes called "asymptotic equipartition principle" and it is equivalent to Shannon's source coding theorem (MacKay, 2003, p.
International contributors offer short communications and review and research papers on widely-ranging topics in this rapidly-changing or field, covering radio frequency waves dissipated by electron damping in tokamaks (machines producing a toroidal magnetic field for confining a plasma) with elliptic and circular magnetic surfaces, analytical treatments of barrier-type problems and plasma theory, interactions of ion beams with plasmas in terms of energy loss and equipartition sum rules, dephasing in Rydberg plasmas, and quasilinear properties of the Einstein Gauss-Bonnet field equations.
Indeed, when non-local effects are important, the influence of the walls is expected to be felt at a considerable distance, and the fact that the mean-free path is long will imply that at each point there is a superposition of populations having different temperatures, thus breaking equipartition.
