Self-similar imploding solutions of the 1D compressible Euler equations with a far field cutoff
Jack Luong, Scott Ramsey, Andrea L. Bertozzi +1
Imploding solutions to the radially symmetric, isentropic, compressible Euler equations have been well-studied, inspired by the work of Guderley. However, these smooth imploding so…

Macroscopic Traffic Flow Network Modeling For Wildfire Evacuation: A Game-Theoretic Junction Optimization Approach with Application to Lahaina Fire
Annie Lu, Hong Kiat Tan, Alexander Xue +2
The 2023 Lahaina wildfire killed 102 people on a peninsula served by a single two-lane highway, making exit lane capacity the binding constraint on evacuation time. We model the ev…
