Simulations of collision times in gravity driven granular flow

We use simulations to investigate collision time distributions as one approaches the static limit of steady-state flow of dry granular matter. The collision times fall in a power-law distribution with an exponent dictated by whether the grains are ordered or disordered. Remarkably, the exponents have almost no dependence on dimension. We are also able to resolve a disagreement between simulation and experiments on the exponent of the collision time power-law distribution.Comment: 7 pages, 5 figure

Notes from the U.S. Census Bureau\u27s March 24, 2016, release of County and Metro Area Population Estimates as of July 1, 2015: The following are key aspects of these new population estimates, summarized in bullet-style form. Figures the Nebraska locations are the focus of this summary; they are listed in no particular order. Associated excel tables contain the data.
