shrink fit process is a useful technique in order to introduce beneficial residual stress in compound pressure vessels. in this paper, the effects of geometrical tolerances on residual stresses have been studied for a compound shrink fitted pressure vessel, practically. three layers, which are designed based on an optimum nominal thickness and overlap dimensions and tolerances, have been fitted...

Tthe Zografos–Balakrishnan-log-logistic (ZBLL) distribution is a new distribution of three parameters that has been introduced by Ramos et el. [1], and They presented some properties of the new distribution such as its probability density function, The cumulative distribution function, The  moment generating function, its hazard (failure) rate function, quantiles and moments, Rényi and Shannon ...

‎Several modifications of the Laplace distribution have been introduced and applied in various fields up to this day‎. ‎In this paper‎,  ‎we introduce a modified symmetric version of the classical Laplace distribution‎.  ‎We provide a comprehensive theoretical description of this distribution‎. ‎In particular‎, ‎we derive the formulas for th...

In this brief note, we highlight some difficulties that can arise when fitting a continuous, symmetric, unimodal distribution to a set of expert’s judgements. A simple analysis shows it is possible to fit a Cauchy distribution to an expert’s beliefs when their beliefs actually follow a normal distribution. This example stresses the need for careful distribution fitting and for feedback to the e...
