Comparing Imperfection Ratio and Imperfection Index for Graph Classes [PDF]

open access: yesRAIRO - 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 \(\text{QSTAB}(G)\).

Exact inference for the risk ratio with an imperfect diagnostic test [PDF]

open access: yesEpidemiology 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 ...

Post-buckling Partial Similitude Scaled Model for Stiffened Cylinders under Axial Compression by Energy Method

open access: yesBuildings, 2022
Considering the geometric nonlinearity and geometric imperfection of stiffened cylinders, the generalized similitude conditions and scaling laws for axial compression post-buckling are established by applying the similitude transformation to the total ...

On determining the imperfection ratio

open access: yesElectronic Notes in Discrete Mathematics, 2006
Perfect graphs constitute a well-studied graph class with a rich structure, reflected by many characterizations w.r.t different concepts. Perfect graphs are, e.g., characterized as precisely those graphs G where the stable set polytope STAB(G) coincides with the clique constraint stable set polytope QSTAB(G). For all imperfect graphs STAB(G) ⊂ QSTAB(G)

Strength Assessment of Rectangular Plates Subjected to Extreme Cyclic Load Reversals

open access: yesJournal of Marine Science and Engineering, 2020
The objective of this study is to investigate the strength of the rectangular plates subjected to cyclic load reversals with varying strain ranges. The finite element solution is implemented to estimate the load-carrying capacity.

Numerical comparison between the thermo-structural behavior of steel and partially encased steel and concrete composite columns in fire

open access: yesRevista IBRACON de Estruturas e Materiais, 2018
The bare steel structural members have a low fire resistance. However, in steel and concrete composite members, the concrete encasement, besides the contribution to the stiffness of the whole system, reduces the amount of heat that reaches the steel ...

Stress-strain assessment of plain dents in gas pipelines

open access: yesFracture and Structural Integrity, 2020
Paper presents the analytical solution of the stress-strain state for a dented pipeline, based on the method of equivalent loads. First off all solution for a harmonic imperfection is found, then using Fourier series expansion a semi-analytical procedure

The effect of imperfections on crack growth rates in cold worked and interference fit holes [PDF]

open access: yesScientific Technical Review, 2019
This work examines the effect of imperfections on fatigue crack growth (FCG) in lap joints (Hi-Lok fasteners). The Finite Element Method (FEM) is used to model the cold-working and interference fit processes.
