Symmetry breaking caused by geometric fluctuations can enable processes that are otherwise forbidden. An example is a perylene bisimide dyad whose dipole moments are perpendicular to each other. Förster-type energy transfer is thus forbidden at the equilibrium geometry since the dipolar coupling vanishes. Yet, fluctuations of the geometric arrangement have(More)
The medial axis of an image pattern is the loci of all inscribed disks that touch two or more boundary points without crossing any of the boundaries. The medial axis transform (MAT) is a powerful representation for objects with inherent symmetry or near-symmetry. The medial axis of 2-D image patterns provides a conceptual design base, with transition to a(More)
Sometimes, engineers have problems understanding the philosophy behind the statistical procedures they need to apply when analyzing materials data. This is not surprising, considering that in many engineering curriculums (i) statistics is limited to one or two (3 or 4 credit hour) courses; (ii) these are rather theoretical , instead of data analysis(More)
