original article   shift work is a common work schedule that has several inappropriate consequences, the most important of which is fatigue. the aim of this study was to invest gate the impact of the shift length on the occupatio al fatigue of operators in filling stations. this cross-sectional study was carried out on operators of the filling station in national iranian oil products distributi...

We propose a new multivariate CUSUM control chart, which is based on selfadaption of its reference value according to the information of current process readings, to quickly detect the multivariate process mean shifts. By specifying the minimum magnitude of the process mean shift in terms of its non-centrality parameter, our proposed control chart can achieve an overall performance for detectin...

The present investigation deals with study of thermoelastic damping and frequency shift of Kirchhoff plate resonators by using generalized thermoelasticity theory of dual-phase-lag model. The basic equations of motion and heat conduction equation are written with the help of Kirchhoff-Love plate theory and dual phase lag model. The analytical expressions for thermoelastic damping and frequency ...

Let x be an m-sequence, a maximal length sequence produced by a linear feedback shift register. We show that the nondeterministic automatic complexity AN (x) is close to maximal: n/2 − AN (x) = O(log 2 n), whereas Hyde has shown AN (y) ≤ n/2 + 1 for all sequences y.

Test Pattern Generators (TPG) are very important logic part of the Circuits that have self-test features. Nowadays, the self-test feature is an in-built part of the modern application hardware designs. This feature enables the user to test and verify the specific hardware failure with the help of the hardware itself. To enable self-test an extra operational and control circuit is required by th...
