A Spatiotemporal Scheme for Process Control Using Image Analysis of Speckle Patterns
Quality and Reliability Engineering International, Volume 41, Issue 5, Page 1773-1788, July 2025.ABSTRACT Conventional image‐based process control schemes require distinct, detectable features (e.g., edges or textures). In the absence of such features, current methods fail or require additional preprocessing. They are also prone to false detections from random noise, dirt, or scratches on the surface.

A novel experience in the use of control charts for the detection of nosocomial infection outbreaks
Clinics, 2011 OBJECTIVE: This study aims to compare different control charts to monitor the nosocomial infection rate per 1,000 patient-days. METHODS: The control charts considered in this study were the traditional Shewhart chart and a variation of this, the ...

On Performance of Two-Parameter Gompertz-Based X¯ Control Charts
Journal of Probability and Statistics, 2020 In this paper, two methods of control chart were proposed to monitor the process based on the two-parameter Gompertz distribution. The proposed methods are the Gompertz Shewhart approach and Gompertz skewness correction method.

Are estimated control charts in control? [PDF]
, 2001 Standard control chart practice assumes normality and uses estimated parameters. Because of the extreme quantiles involved, large relative errors result. Here simple corrections are derived to bring such estimated charts under control.

Shewhart’s Control Chart: Some Observations
, 1999 Data Analysis in Shewhart’s Control Chart, to use the original m samples n sized intensities, is the main subject of this paper. Given m × n intensities we examine three alternatives to sintetize the variability: a) arithmetic mean of m standard deviations (' S); b) root mean square of m variances (" S); c) global dispersion ("" S).
