Although it has been claimed in two different papers that the maximum cardinality cut problem is polynomial-time solvable for proper interval graphs, both of them turned out to be erroneous. In this work we consider parameterized complexity problem. We show proper/unit graphs FPT when by number non-empty bubbles a column its bubble model. then generalize result more general graph class defining...

background : most diagnostic tests for biliary atresia (ba) are invasive. this study evaluates the sensitivity and specificity of serum  tumor necrosis factor-α (tnf-α) for diagnosing extra hepatic biliary duct atresia (ehba) in infants. materials and methods : infants with cholestasis who were admitted to children′s medical center hospital were evaluated. a total of 50 infants (20 with ehba an...

In this paper we consider the problem of the evaluation of system reliability, in which the lifetimes of components are described using a fuzzy exponential distribution. Formula of a fuzzy reliability function and its α-cut set are presented. The fuzzy reliability of structures is defined on the basis of fuzzy number. Furthermore, the fuzzy reliability functions of k -out-ofm system, series sys...
