Scalar Conservation Laws with Nonconstant Coefficients with Application to Particle Size Segregation in Granular Flow

Journal of Nonlinear Science, 20(6), 689–707.

By: L. May n, M. Shearer n  & K. Daniels n 

Contributors: L. May n, M. Shearer n  & K. Daniels n 

author keywords: Conservation laws; First order partial differential equations; Granular flow; Particle segregation
topics (OpenAlex): Landslides and related hazards; Granular flow and fluidized beds; Soil and Unsaturated Flow
TL;DR: A velocity profile is measured from experimental data and initial value problems that mimic the segregation observed in the experiment are solved, thereby verifying the value of the continuum model. (via Semantic Scholar)

Shear-driven size segregation of granular materials: Modeling and experiment

PHYSICAL REVIEW E, 81(5).

By: L. May n, L. Golick n, K. Phillips n, M. Shearer n  & K. Daniels n 

topics (OpenAlex): Granular flow and fluidized beds; Landslides and related hazards; Soil and Unsaturated Flow
TL;DR: The Gray-Thornton model of segregation is applied to a granular flow with an exponential shear profile, and the model successfully captures the presence of a fast mixing process and relatively slower resegregation process, but the model predicts a finite resegregation time, while in the experiment resegregation occurs only exponentially in time.

2007 journal article

Shifts of finite type and Fibonacci Harps

APPLIED MATHEMATICS LETTERS, 20(2), 138–141.

By: A. Crannell *, S. May n & L. Hilbert n

author keywords: fractal strings; lattice strings; subshifts; Cantor sets; baker's map; Fibonacci
topics (OpenAlex): Cellular Automata and Applications; Mathematical Dynamics and Fractals; semigroups and automata theory
TL;DR: An explicit connection is made between the Fibonacci Harp and two well-known dynamical systems: subshifts of finite type and the baker’s map on the unit interval. (via Semantic Scholar)
