Comparing Imperfection Ratio and Imperfection Index for Graph Classes [PDF]
RAIRO - Operations Research, 2008 Summary: Perfect graphs constitute a well-studied graph class with a rich structure, reflected by many characterizations with respect to different concepts. Perfect graphs are, for instance, precisely those graphs \(G\) where the stable set polytope \(\text{STAB}(G)\) coincides with the fractional stable set polytope \(\text{QSTAB}(G)\).

Multi-objective optimization of covering parameters for cotton/spandex core-spun yarn using grey relational analysis in conjunction with the Taguchi technique. [PDF]
Sci RepThe growing need for high-performance stretchable fabrics led scientists to innovate a new spinning technique, especially for manufacturing cotton/spandex core-spun yarns. This type of yarn is spun by using spandex monofilament or multifilament as a core,

Analysis of key parameters influencing performance for assembled aluminum alloy buckling-restrained braces. [PDF]
Sci RepBuckling-restrained braces (BRBs) are widely used in engineering practice as both load-bearing and energy-dissipating components. However, the application of traditional BRBs is often limited by their self-weight, particularly in long-span structures. To

Exact inference for the risk ratio with an imperfect diagnostic test [PDF]
Epidemiology and Infection, 2016 SUMMARYThe risk ratio quantifies the risk of disease in a study population relative to a reference population. Standard methods of estimation and testing assume a perfect diagnostic test having sensitivity and specificity of 100%. However, this assumption typically does not hold, and this may invalidate naive estimation and testing for the risk ratio ...
