In this research, the influence of Bi nanoparticles addition on the high temperature superconductor BSCCO-2223 was studied. For this purpose, the samples were synthesized by the conventional sol-gel method. Then, the Bi nanoparticles with x= 0.00, 0.03, 0.06, 0.12wt% was added to BSCCO-2223. The structural characterization of all the samples was done by X-ray diffraction pattern (XRD). Also, th...

Receiver Operating Characteristics (ROC) curve serves as a statistical tool to measure the quality of Biomarker in 5 accessing the accuracy of any diagnostic test. This paper portrays the historical background of ROC curve and reviews various 6 parametric methods adopted for fitting the ROC curve till date. The parametric ROC models that are considered in this paper 7 are Bi-Normal, Bi-Gamma, B...

let $s$ be an ordered semigroup. a fuzzy subset of $s$ is anarbitrary mapping   from $s$ into $[0,1]$, where $[0,1]$ is theusual interval of real numbers. in this paper,  the concept of fuzzygeneralized bi-ideals of an ordered semigroup $s$ is introduced.regular ordered semigroups are characterized by means of fuzzy leftideals, fuzzy right ideals and fuzzy (generalized) bi-ideals.finally, two m...

In this paper, we introduce the notion of a bi-cooperative game with fuzzy bi-coalitions and discuss the related properties. In real game theoretic decision making problems, many criteria concerning the formation of coalitions have bipolar motives. Our model tries to explore such bipolarity in fuzzy environment. The corresponding Shapley axioms are proposed. An explicit form of the Shapley valu...

Introduction: Acquiring a high quality image has assigned an important concern for obtaining accurate diagnosis in nuclear medicine. Detector and collimator are critical component of Single Photon Emission Computed Tomography (SPECT) imaging system for giving accurate information from exact pattern of radionuclide distribution in the target organ. The images are strongly affect...

Investigating the longitudinal optical conductivity of graphene systems, which is the mostimportant property for opto-electronic devices, for three-layer graphene systems theoretically and numerically is the main purpose of this study. Each layer can be mono- or bi-layer graphene. Separation between layers has been denoted by d, selected to be about ten nanometers. The carrier densities i...

Effect of different fillers on natural rubber compounds was investigated through curing, mechanical properties and morphology studies for improving mechanical performance of rubber articles. In this work, natural rubber blends with Silica as Single-filler compounds, and blends with Silica and Carbon black as Bi-filler compounds were considered. Then, natural rubber blends with Silica, Carbon bl...
