Why some things are darker when wet.
Angstrom has proposed that rough absorbing materials are darker when wet because their diffuse reflection makes possible total internal reflection in the water film covering them, increasing the likelihood of the absorption of light by the surface. His model is extended here in two ways: the probability of internal reflection is calculated more accurately, and the effect on absorption of the de...
متن کاملSlippery when wet: the effects of local alcohol access laws on highway safety.
Using detailed panel data on local alcohol policy changes in Texas, this paper tests whether the effect of these changes on alcohol-related accidents depends on whether the policy change involves where the alcohol is consumed and the type of alcohol consumed. After controlling for both county and year fixed effects, we find evidence that: (i) the sale of beer and wine may actually decrease expe...

متن کاملEffective Wet-in-Wet Flow Synthesis for Ink Diffusion
Wet-in-wet flow effect is a famous phenomenon in Chinese ink paintings. In this paper, we propose a new two-stage algorithm to synthesize this renowned effect. Given a reference image, in the first stage, we render the reference image using a new color ink diffusion synthesis algorithm. This physically-based algorithm explores a new and more sensitive Kubelka-Munk (SK-M) equation. As a result, ...
