Sparse Dynamics for Partial Differential Equations
Hayden Schaeffer, Stanley Osher, Russel Caflisch +1
We investigate the approximate dynamics of several differential equations when the solutions are restricted to a sparse subset of a given basis. The restriction is enforced at ever…
On Cellular Automata Models of Traffic Flow with Look-Ahead Potential
Cory Hauck, Yi Sun, Ilya Timofeyev
We study the statistical properties of a cellular automata model of traffic flow with the look-ahead potential. The model defines stochastic rules for the movement of cars on a lat…
Perturbed, Entropy-Based Closure for Radiative Transfer
Martin Frank, Cory D. Hauck, Edgar Olbrant
We derive a hierarchy of closures based on perturbations of well-known entropy-based closures; we therefore refer to them as perturbed entropy-based models. Our derivation reveals…
