The generalized half-logistic distribution is ideal to fit the lifetime of some products, such as ball bearings and electrical insulation. In this paper, we aim extend scope by creating a motivated bivariate version. We thus introduce using Farlie Gumbel Morgenstern (FGM) copula, which called FGM (FGMBGHLD for short). particular, FGMBGHLD finds application in describing datasets that have weak ...

The Strength of Motivation for Medical School (SMMS) questionnaire is designed to determine the strength of motivation of students particularly for medical study. This research was performed to establish the validity evidence for measuring strength of motivation for medical school. Internal structure and relations to other variables were used as the sources of validity evidence. The SMMS questi...

CONTEXT The reliable measurement of shoulder strength is important when assessing athletes involved in overhead activities. Swimmers' shoulders are subject to repetitive humeral elevation and consequently have a high risk of developing movement-control issues and pain. Shoulder-strength tests performed in positions of elevation assist with the detection of strength deficits that may affect inju...

The paper is inspired by the stress-strength models in the reliability literature, in which given the strength (Y ) and the stress (X) of a component, its reliability is measured by P (X < Y ). In this literature, X and Y are typically modeled as independent. Since in many applications such an assumption might not be realistic, we propose a copula approach in order to take into account the depe...

The reliability of the stress-strength model attracted many statisticians for several years owing to its applicability in different and diverse parts such as engineering, quality control, economics. In this paper, system estimation containing Kth parallel components will be offered by four types shrinkage methods: constant Shrinkage Estimation Method, Function Estimator, Modified Thompson Type ...

The objective of this paper is to investigate the effect of copulas for constructing the bivariate distribution of shear strength parameters on system reliability of geotechnical structures. First, the bivariate distribution of shear strength parameters is constructed using copulas. Second, the implementation procedure of system reliability analysis using direct Monte Carlo simulation (MCS) is ...

considering the fact that rocks fail faster under tensile stress, rock tensile strength is of greatimportance in applications such as blasting, rock fragmentation, slope stability, hydraulic fracturing,caprock integrity, and geothermal energy extraction. there are two direct and indirect methods tomeasure tensile strength. since direct methods always encompass difficulties in test setup, indire...

this research was performed to determine the efficiency effect of sedimentary environment of kerman city area on soil structure bycomparing natural and reconstituted consolidation curves. in this regard, four different criteria such as sensitivity strength, stresssensitivity, schmertman criteria and the result of the uniaxial compression test were used. the base of these criteria is to compare ...

Ensuring the safe operation of pipe fittings in a natural gas station is critical. The irregular shape tee easily leads to uneven mechanical properties manufacturing process. strength may be lower than requirements due its unqualified heat-treatment As result, selecting reliable way repairing low-strength pipes pressing concern. To repair pipes, special-shaped epoxy steel sleeve (SSESS) was des...

This paper aims to propose a bootstrap method for characterizing the effect of uncertainty in shear strength parameters on slope reliability. The procedure for a traditional slope reliability analysis with fixed distributions of shear strength parameters is presented first. Then, the variations of the mean and standard deviation of shear strength parameters and the Akaike Information Criterion ...
