Scaling of dynamic bending response of metal tube under impact loading considering strain rate effects

open access: yesAIP Advances, 2020
Based on the engineering background of the heavy drop impacting metal tube, the scaling law without considering the strain rate effects was deduced according to the π theorem.

ON PERMUTATION LOCATION–SCALE TESTS [PDF]

open access: yesStatistics in Transition New Series, 2019
Abstract Statisticians are constantly looking for methods of statistical inference that would be both effective and would require meeting as few assumptions as possible. Permutation tests seem to fit here, as using them makes it possible to perform statistical inference in situations where classical parametric tests do not work ...

Test method for de-icing salt-frost scaling in high-performance concrete

open access: yesMethodsX, 2018
This paper describes a de-icing salt-frost scaling test method for analysis of the salt-frost scaling behaviour in high-performance concrete with various binders. The method was therefore designed to result in considerable scaling damage for the concrete

Scaling Metric Measurement Invariance Models

open access: yesMethodology, 2023
This paper aims at clarifying the questions regarding the effects of the scaling method on the discrepancy function of the metric measurement invariance model. We provide examples and a formal account showing that neither the choice of the scaling method
