Dimensional Analysis under Linguistic Pythagorean Fuzzy Set
(2021-03-08)Dimensional analysis under linguistic Pythagorean fuzzy set (DA-LPFS) is a technique to handle qualitative (intangible) as well as the interactions between criteria, by combining dimensional analysis (DA) and Pythagorean ... -
Dimensional Analysis under Pythagorean Fuzzy Approach for Supplier Selection
(2019-03-06)The supplier appraisal process is one of the most important decision problems for companies focused on improving supply chain costs. Supplier selection is typically a multi-criteria decision making (MCDM) issue, as there ... -
Direct and Indirect measurements of the magnetic and magnetocaloric properties of Ni0.895Cr0.105MnGe1.05 melt-spun ribbons in high magnetic fields
(2019-10-15)We report the magnetic and magnetocaloric properties of rapidly solidified Ni0.895Cr0.105MnGe1.05 melt-spun ribbons studied by both direct (adiabatic temperature change) and indirect (isothermal magnetic entropy change) ... -
Discrimination between the lognormal and Weibull distributions by using multiple linear regression
(2018-03-13)In reliability analysis, both the Weibull and the lognormal distributions are analyzed by using the observed data logarithms. While the Weibull data logarithm presents skewness, the lognormal data logarithm is symmetrical. ... -
