Where the Horizon Is Drawn

Boundary Placement and the Time Lag of a Graded Diffusion Barrier

A research poster from the School of Underlying Conditions proves that a layered model of a graded diffusion barrier reproduces its steady flux wherever the layer boundaries are drawn but not its time lag, and bounds the lag error by the layers' thickness. In a worked sigmoidal example every two-layer boundary overestimates the lag, the least-error boundary lies below the half-contrast depth, and a third, transitional layer brings the lag within 6%.
