Statistical Symmetry Analysis of Scallops
Stein-Erik Lauritzen

Abstract

A graphical method is suggested for measurement of inflection point angles in scallop copies on paper. Statistical analysis of the angle pairs from large numbers of scallops allow a quantitative judgement of the asymmetries of the scallops and, hence, of the flow direction. This is a safer method than judgment of scallop directions by inspection and finger touching.
