Abstract. The modern unification of the European standards EUROCODE requires securing a constant quality of metallurgical production in the EU countries. In this paper, experimentally found statistical characteristics of yield stress, ultimate tensile strength and ductility of Czech and Austrian steel are presented. In the probabilistic reliability analysis, the experimentally found yield stres...

Methods for estimating structural reliability using probability ideas are well established. When the residual ultimate strength of a buried pipeline is exceeded the limit, breakage becomes imminent and the overall reliability of the pipe distribution network is reduced. This paper is concerned with estimating structural failure of underground flexible pipes due to corrosion induced excessive de...

The inverse Lomax distribution has been extensively used in many disciplines, including stochastic modelling, economics, actuarial sciences, and life testing. It is among the most recognizable lifetime models. purpose of this research to look into a new important aspect distribution: calculation fuzzy stress-strength reliability parameter RF = P(Y < X), as?suming X Y are random independent v...

In this study, we consider the stress-strength reliability and mean remaining strength of a series system with cold standby redundancy at component levels. Classical Bayesian approaches are studied in order to obtain estimates when underlying stress, components follow exponential distribution different parameters. Bayes approximated by using Lindley’s approximation Markov Chain Monte Carlo meth...

Continuous stress–strength interference (SSI) model regards stress and strength as continuous random variables with known probability density function. This, to some extent, results in a limitation of its application. In this paper, stress and strength are treated as discrete random variables, and a discrete SSI model is presented by using the universal generating function (UGF) method. Finally...

  Background: The Motricity Index was used to measure strength in upper and lower extremities after stroke. The weighted score based on the ordinal 6 point scale of Medical Research Council was used to measure maximal isometric muscle strength. There is dearth of articles dealing with the reliability of this method. Therefore, the aim of this study was to determine the test retest reliability o...

For given random variables X and Y , the distributions of the product |XY | and the ratio |X/Y | are of interest in many areas of the sciences. In traditional portfolio selection models, certain cases involve the product of random variables. The best examples of this are in the case of investment in a number of different overseas markets. In portfolio diversification models (see, e.g., Grubel [...

patients and methods the study was performed with the participation of 172 cancer patients aged 18 and over. factor analysis (principal components analysis) was used to assess construct validity. criterion validities were tested by computing spearman correlation between candi and hospital anxiety depression scale (hads), and brief symptom inventory (bsi) (convergent validity) and quality of lif...
