Given a set of irregularly sampled 3D polygonal curves representing composite fibres within micro-computed tomography volume, new approach based on the Frenet–Serret formulas is proposed to measure point curvature and waviness along polyline even when its oscillations are not coplanar. However, direct computation measures would lead ill-formed results depending variant externalities across acqu...

Abstract The verification of different plate bending problems require a punctual measurement method the bent shape. However, with proper curvature procedure calculations can be made more accurate. This is due to workaround this provides by neglecting inaccuracies beam theory and tensile tests, measuring directly function between moment for given sheet metal. measurements in paper are help digit...

The aim of this research was to accurately measure the surface of the semi lunar articular surface of the pelvis (facies lunata acetabuli) and the variability of the acetabular geometry, as well as to determine the correlation between measured parameters. 30 macerated anatomical specimens of pelvic bones were measured. The radius and depth were measured in the classical way, while cartilaginous...
