In this note, we characterize the convex hull of the Stiefel manifold and we find its strong convexity parameter. We also introduce the notion of roundness of a set and show that the Stiefel manifold is round.

The purpose of this paper to introduce the concept of roundness is fuzzy metric spaces. Also some theorems and definitions is given on round fuzzy metric spaces. Mathematics Subject Classification: 54A40, 54E35

This paper describes and explains some regularities in the frequency of numbers in text. An analysis of number frequencies in text corpora in Dutch, English, German, and French confirms the expectation that frequency is highly dependent on two factors: magnitude and roundness. Roundness (defined as number frequency in an approximation context) proves to be related to three arithmetical properti...

OBJECTIVE To test the homemade ring fixator as a tool for correction of bony deformity. MATERIAL AND METHOD The authors developed an aluminum alloy ring fixator and tested it to find out the accuracy of manufacturing and strength of the ring systems under axial load with the Roundness Testing Machine and Lloyd Universal Testing Machine. RESULTS The mean diameter of the twenty five-drill hol...

In aquaculture, the process of hybridization is used to produce animals that have better growth rates, meat quality, and higher resistance and tolerance to environmental variations than their parental species. The identification of a hybrid fish may require a DNA-based technology that is an expensive process. In this study, the sagittal otolith shape of hatchery-reared brook trout (Salvelinus f...
