Particle deposition onto a flat plate with various slopes
In this work, a numerical simulation of the deposition of small suspended particles onto a flat plate with various degrees of inclination is performed. The particle deposition rates are obtained for various Reynolds and Rayleigh number groups
Temporal evolution of the "thermal" and "superthermal" income classes in the USA during 1983-2001
Personal income distribution in the USA has a well-defined two-class
structure. The majority of population (97-99%) belongs to the lower class
characterized by the exponential Boltzmann-Gibbs ("thermal") distribution,
whereas the upper class (1-3% of population) has a Pareto power-law
("superthermal") distribution. By analyzing income data for 1983-2001, we show
that the "thermal" part is stationary in time, save for a gradual increase of
the effective temperature, whereas the "superthermal" tail swells and shrinks
following the stock market. We discuss the concept of equilibrium inequality in
a society, based on the principle of maximal entropy, and quantitatively show
that it applies to the majority of population.Comment: v.3: 7 pages, 5 figures, EPL style, more references adde
