Some Efficient Measures of Relative Dispersion

Some Aspects of Turbulent Relative Particle Dispersion

In this paper, several aspects of the turbulent relative particle dispersion are considered, many of which are motivated by laboratory experiment and numerical simulation results. These are, * spatial intermittency effects, (a) reduction of relative particle dispersion in 3D; (b) prevalence of power-law scaling of relative particle dispersion in 2D enstrophy cascade; * quasi-geostrophic aspects...

Inflation And Relative Price Dispersion: Evidence For Iran

Dispersion measures and dispersive orderings

In this paper, the comparison of random variables according to the functionals of a general class of dispersion measures is characterized in terms of the dilation order. The Gini’s mean di¤erence is a particular member of this general class. In addition, a new and weaker order, called the second-order absolute Lorenz ordering, is introduced, and we judge random variables according to certain fu...

Some perspectives on dispersion

Pulsed Gradient Nuclear Magnetic Resonance provides direct insight regarding the translational motion of spin-bearing molecules. These methods gain a second dimension when the simple gradient pulse pair is enhanced by a second pair. Where the motion encoding of the two pairs is opposite, flow effects are removed from the echo attenuation, making it possible to measure diffusion in the presence ...

Relative Centrality Measures

In this paper we present natural and compelling generalizations of four widely used centrality measures to local and global measures relative to subsets of nodes in a network. These new relative centrality measures can provide insight into network properties with respect to subsets. Definitions of these measures are given and various properties are investigated.
