It was found that the sizes of the largest avalanches just preceding the lattice system were power- law distributed. Grasso, J.-R.Ī two-threshold model was proposed for scaling laws of noninteracting snow avalanches. Two-threshold model for scaling laws of noninteracting snow avalanchesįaillettaz, J. Copyright 1998 by the American Geophysical Union. However, we suggest to use higher order moments as promising diagnostic tools for mapping the contributions of various remote magnetospheric sources to local observatory data. ESS does not allow to make an unambiguous statement about the non triviality of scaling laws in "geomagnetic" turbulence. We found power law scalings for components of the homogeneous dissipation rate (É›) obeying the non-Richardson-Kolmogorov cascade as É›uËœku3 /2/(l R elm ), É›vËœkv3 /2/l, kvËœku/R el2 m, 0 l/5) a clear departure from the expected universality is observed for n > 6.
At infinite Reynolds number limit, the flow evolves as general power law and a new exponential law of streamwise distance, consistent with the criterion of equilibrium similarity hypothesis. We establish theoretically multitude scaling laws of a self-similar (statistical) axisymmetric turbulent wake. Multitude scaling laws in axisymmetric turbulent wake We will present results from a numerical simulation of asteroid collisional evolution over the age of the solar system using proposed scaling laws and a range of hypothetical initial populations. The effects of collisions among the asteroids produce the following observables: (a) the size distribution has been significantly shaped by collisions, (b) collisions have produced about 25 well recognized asteroid families, and (c) the basaltic crust of Vesta has been largely preserved in the face of about 4.5 Byr of impacts. (1994, Goutelas Proceedings) and tested the suite of proposed scaling algorithms against observations of the main-belt asteroids. We have expanded upon the work of Davis et al. The present situation is that there are several proposed scaling laws that differ by as much as two orders of magnitude at particular sizes. (1998, Icarus 135, 431-440) used the observed asteroid size distribution to infer a scaling algorithm. Ever more sophisticated computation methods have also been developed prominent among these are hydrocode simulations of collisional disruption by Benz and Asphaug (1999, Icarus, in press), Love and Ahrens (1996, LPSC XXVII, 777-778), and Melosh and Ryan (1997, Icarus 129, 562-564). How large bodies break up in response to energetic collisions is a problem that has attracted considerable attention in recent years. Testing Collisional Scaling Laws: Comparing with Observables
