Research ArticleOpen accessIn the abstractComparison of the Known Hypotheses of Lateral Buckling in the Elastic-Plastic States of Thin-Walled Semi-Slender ColumnsKrzysztof MurawskiStability of structures, as known, is a challenging issue, especially in critical engineering, i.e., in designing structures which in a wrong design process could cause a catastrophe. The avoidance of possible stability troubles is mandatory. In this study, the simplifications and hypotheses of loss of stability by lateral buckling in elastic-plastic states of semi-slender columns axially compressed by force are … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 21 Dec 2020 · 6,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Permutation Test for Comparing Two Correlated Receiver Operating Characteristic CurvesOkeh Uchechukwu Marius, Onyeagu SidneyThe area under the Receiver Operating Characteristic (ROC) curve (AUC) is a summary measure when comparing two ROC curves.
