background: one of the methods used for standard setting is the borderline regression method (brm). this study aims to assess the reliability of brm when the pass-fail standard in an objective structured clinical examination (osce) was calculated by averaging the brm standards obtained for each station separately. materials and methods: in nine stations of the osce with direct observation the e...

BACKGROUND Cut-point finding is a crucial step for clinical decision making when dealing with diagnostic (or prognostic) biomarkers. The extension of ROC-based cut-point finding methods to the case of censored failure time outcome is of interest when we are in the presence of a biomarker, measured at baseline, used to identify whether there will be the development, or not, of some disease condi...

OBJECTIVE To review existing methods and illustrate the use of a new, simple method for identifying inaccurate reports of dietary energy intake (rEI). DESIGN Comparison of rEI with energy requirements estimated by using total energy expenditure predicted (pTEE) from age, weight, height and sex using a previously published equation. Propagation of error calculations was performed and cut-offs ...

To maintain the structural integrity of the engineering components, having an exact knowledge of residual stresses is important. Among all mechanical strain relief techniques to measure residual stresses, slitting is one of the youngest. This technique relies on the introduction of a narrow slot of increasing depth in a part containing residual stresses. Similar to other measurement techniques,...

Learning models and related results depend on the quality of the input data. If raw data is not properly cleaned and structured, the results are tending to be incorrect. Therefore, discretization as one of the preprocessing techniques plays an important role in learning processes. The most important challenge in the discretization process is to reduce the number of features’ values. This operat...

background : homicide is killing of a human being by another human being. various methods like strangulation, cut throat, stabbing etc may be used for homicide; however combination of two mechanisms is rare. case report: hereby we present a rare case with unexpected appearance of two different mechanisms of homicide applied over same region, wherein body of a female was referred to us with hist...

Karger (SIAM Journal on Computing, 1999) developed the first fully-polynomial approximation scheme to estimate the probability that a graph G becomes disconnected, given that its edges are removed independently with probability p. This algorithm runs in n5+o(1)ǫ−3 time to obtain an estimate within relative error ǫ. We improve this run-time through algorithmic and graph-theoretic advances. First...

[1] The paper discusses a generalized minimum residual (GMRES) iterative solution of the magnetic field integral equation (MFIE) applied to frequency domain scattering problems at medium and high frequencies. First, the performance of the original MFIE is studied, for the perfectly electrically conducting (PEC) sphere. It is shown that the residual error and the solution error do not correlate ...
