News Context: We can calculate true scale-invariant roughness parameters. We believe this new understanding of roughness across scales will open the door to finally solving this age-old puzzle in surface analysis. Dr. Jacobs breakthrough is the first step in an uphill, and very steep, battle to create and validate these models.
Paper Context: # , 0 . Since we do not know the value of the slope ! " By assuming that the distribution of slopes in x-and ydirection is independent (which is true for a Gaussian distribution of slopes), we can express ! "
