“…Several authors have published work on nonnormal quality measurements for various chart types. Lashkari and Rahim26 consider the CUSUM chart, and Nagendra and Rai27 and Rahim28 consider the economic design of charts. All of this work models the probability density function of the quality measurement X by the first four terms of the Edgeworth series, which are functions of the first four moments.…”

We report the advantages of the adsorption and electrooxidation of oligonucleotides and calf‐thymus double stranded DNA (dsDNA) at glassy carbon electrodes (GCE) modified with a dispersion of multiwalled carbon nanotubes (MWCNT) in poly‐L‐lysine (Plys) (GCE/MWCNT‐Plys). Important enhancement in the guanine oxidation signal was obtained by adsorptive stripping voltammetry (AdSV) due to a most favorable interaction between the negatively charged DNAs and the positively charged Plys that support the MWCNT. The layer of oligo(dG)11 immobilized at GCE/MWCNT‐Plys was successfully used for the selective detection of the hybridization event using oligo(dG)11/oligo(dC)11 as model.

We consider the joint economic-statistical design of X and R control charts under the assumption that the quality measurement and the in-control time have Johnson and Weibull distributions. The Johnson distribution is general in that it can be made to fit all possible values of skewness and kurtosis. The four parameters-the sample size n, time h between successive samples, and the control factors k 1 and k 2 for the X and R charts-are determined so that the mean hourly loss-cost is minimized under constraints on the Type I and II error probabilities. We have generalized the Costa model to accommodate the Johnson and Weibull distributions. Sensitivity to nonnormality, shift, and Weibull scale parameter is considered in our analysis. Our sensitivity analysis shows that the optimal design parameters are sensitive to nonnormality. Comparisons of the fully economic and economic-statistical designs are given.
