Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.
Technology Reports of Kansai University (ISSN: 04532198) is a peer-reviewed journal. The journal covers all sort of engineering topic as well as mathematics and physics. the journal's scopes are

Peripheral arterial disease (PAD) affecting the femoropopliteal artery (FPA) is usually due to a chronic atherosclerotic obstruction that reduces blood flow to the lower limb. FPA stenting is an increasingly popular minimally invasive procedure that uses self-expanding nickel-titanium alloy (NiTi) stents. Benchtop mechanical stent testing allows direct evaluation of the device without interference from patient-dependent factors. The purpose of this study is to provide a ranking for different models of FPA stent that are frequently used to treat blocked FPA by applying the pictorial selection method for the criterion of variable mechanical load modes that were carried out in the experimental research studies. The results ranking of the FPA stent models was the first ranking position for SMART Control (Model I) with a net score of 3.65, the second model rank was for Complete SE (Model II) with a net score of 3.55, then SMART Flex. (Model III) with a net score of 3.40, and the classification of the last stent model was with a net score of 2.25, 2.20, and 2.10 for each one of Innova (Model X), Zilver (Model XI), and Viabahn (Model XII), respectively. There was none study has ranked the FPA stent models based on the mechanical criteria, which evaluate the mechanical performance for each stent.
In statistics copulas study and their applications are growing field which are very efficient functions in statistics and specially in statistical inference. Copula is used for constructing families of bivariate and multivariate distributions and a way of studying measure of dependence structure also, this copula couple multivariate distribution functions to their one-dimensional marginal distribution functions, which are uniformly distributed in [0,1]. They are several methods for constructing copulas as inverse method, Rüschendorf’s method, geometric method, algebraic method, and Archimedean method hence, we construct new copula according to univariate function. Copulas have appeared in many important fields such as civil engineering, biomedical studies, physics, quantitative finance, economics, climatology, social science, and insurance risk management which confirms its importance. This paper introduces some bivariate copulas as product, Clayton, Frank, Ali-Mikhail-Haq, Farlie-Gumbel-Morgensten, and Gumbel-Hougaard copulas. A new class of bivariate copula is introduced which depending on a univariate function. The basic properties which satisfied that is a true copula namely, the boundary conditions and the 2-increaing property are proved. Several properties of this class are studied as concordance ordering, dependence, symmetry, and measures of association. Further, example is proposed generated by a univariate function that described parametric family of copula as product copula.
