The effect of measurement errors on adaptive and non-adaptive control charts has been occasionally considered by researchers throughout the years. However, that effect on the variable sample size and sampling interval (VSSI) control charts has not so far been investigated. In this paper, we evaluate the effect of measurement errors on the VSSI control charts. After a model development, the effe...

Industrial organizations are complex systems` where the interactions among the various functions such as Sales, Distribution, Manufacturing, Materials, Finance, Human Resources and Maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. However, since most of these or-ganizations have a `Functional Structure`, each function or department works towards ...

because of reducing the number of spectators of football premier league, this study is seeking for identifying factors put the most impact on this decline. the statistical population consisted of all spectators in iran football premier league in 2015-16, out of which 395 spectators were randomly selected as the research samples. the data were collected via a researcher-made questionnaire. the f...

The transient response of passivated metallic electrode system under potential step was analyzed based on a linear model, and a technique for calculating the parameters characterizing the growth and dissolution of passive film was proposed. It is believed that the information which is expected to be gained from the impedance measurement can be obtained by this technique and that this technique ...

This paper presents a mathematical model for the vibration analysis of a three-component piezoelectric force sensor. The cubic theory of weakly nonlinear electroelasticity is applied to the model for describing the electromechanical coupling effect in the piezoelectric sensing elements which operate in thickness-shear and thickness-stretch vibration modes. Hamilton's principle is used to derive...
