Abstract: Abstract Interferometry, which measures the difference between a reference surface and a test surface, is widely used in high-precision testing. Usually the reference surface is considered as perfect and the surface errors there can be… read more here.

Abstract: The morphological response of two-dimensional curved elastic sheets to an isolated defect (dislocation/disclination) is investigated within the framework of Föppl-von Kármán shallow shell theory. The reference surface, obtained as a shell configuration in the absence… read more here.

Abstract: ABSTRACT Images of laser-induced fluorescence (LIF) of hydroxyl radicals (OH) produced in premixed flames are here analyzed from the perspective of fractal theory applied to flame wrinkling. The results confirm that the signal isosurface showing… read more here.
