The comprehensive index method has difficulties in evaluating the influence of air pollutant concentration changes on ambient quality. Thus, a evaluation based entropy weights and trend-regulating factors is proposed. According to information rates 6 pollutants, single weight proposed by integrating it with single-quality index, which reflects variations periods. Spearman’s rank correlation coe...

this paper discusses different important gas permeation models such as “maxwell”, “bruggeman”, “lewis-neilson”, and “pal” models to predict “mixed matrix membranes” (mmms) performance. the main parameter considered and discussed is the permeability of hydrogen on carbon nanotubes (cnts)-mmm. for evaluation of the theoretical models, experimental data of permeability for h2 were compared to the ...

The proposals of the Basel Committee on Banking Supervision for the revision of minimum requirements for bank’s risk capital leave the quantification of lossgiven-default (LGD) parameter used for capital calculation unspecified. This paper proposes a new methodology for incorporating LGD parameter explicitly into the Basel risk weight function. Numerical examples based on the new methodology ar...

Background: The attitude towards lactation is one of the best predictors of breastfeeding. Iowa Infant Feeding Attitudes Scale (IIFAS) is used to measure the attitude toward lactation. IIFAS is a valid and reliable tool but factorial structure of this tool was reported various in different studies. The aim of this study is to assess factorial structure of IIFAS. Materials and Methods: An extens...

Field monitoring of water quality during the autumn flood season in middle and lower reaches Yellow River 2021 was carried out. During this period, a host methods, including single-factor evaluation method, index fuzzy mathematics were utilized to evaluate status. The relevant findings indicate that mainstream tributaries is excellent, which meets function zoning goals. In particular, method em...
