In this paper we study the problem of computing the smallest-width annulus for a convex polytope in R d. This generalizes a topic from tolerancing metrology to higher dimensions, of which the planar case has been investigated by Swanson, Lee and Wu. We show this problem to be equivalent to the problem of computing diierent variants of Hausdorr-minimal spheres. We can formulate the latter proble...

The results of our investigation of several measurements on digitized 2D and 3D objects with fuzzy borders are presented. The performance of surface area, volume, and roundness measure estimators for digitized balls with fuzzy borders is analyzed. The method we suggest provides significant improvement in precision, compared to analogous estimation results obtained on a crisp (hard) segmentation...

In this paper, a classifier is proposed and trained to distinguish between bulking and non-bulking situations in an activated sludge wastewater treatment plant, based on available image analysis information and with the goal of predicting and monitoring filamentous bulking. After selecting appropriate activated sludge parameters (filament length, floc fractal dimension and floc roundness), an L...

Benzenoid hydrocarbons have regular structures, attracting the opportunity to test structural descriptors of their series. In present study, we compared information entropy, Wiener indices, topological efficiencies, roundness, and symmetries oligoacenes, phenacenes, helicenes. We found discussed mismatches between symmetry benzenoids. Among studied series, helicenes demonstrate parity effect wh...

In this paper, based on the as-cast CuSn10P1 alloy. Semi-solid alloy billet was prepared by cold-rolled isothermal treatment strain-induced melting activation (CRITSIMA). The effects of cold-rolling reduction, temperature, and time microstructure semi-solid copper were studied metallographic microscope Image-Pro Plus software. changes primary elements in analyzed briefly a scanning electron (SE...
