Role of Horizontal Eddy Diffusivity within the Canopy on Fire Spread

open access: yesAtmosphere, 2020
Wind profile observations are used to estimate turbulent mixing in the atmospheric boundary layer from 1 m up to 300 m height in two locations of pine forests characteristic of the southeast US region, and to 30 m height at one location in the northeast.

The Dynamics of the Forest Graph Operator

open access: yes, 2016
In 1966, Cummins introduced the "tree graph": the tree graph $\mathbf{T}(G)$ of a graph $G$ (possibly infinite) has all its spanning trees as vertices, and distinct such trees correspond to adjacent vertices if they differ in just one edge, i.e., two ...
