The CCC-r chart is developed based on cumulative count of a conforming (CCC) control chart that considers the cumulative number of items inspected until observing r nonconforming ones. Typically, the samples obtained from the process are analyzed through 100% inspection to exploit the CCC-r chart. However, considering the inspection cost and time would limit its implementation. In this paper, w...

Abstract The RMAX chart was proposed to control the covariance matrix of two quality characteristics. monitoring statistic is maximum standardized sample ranges from bivariate observations In this article, we investigate performance synthetic charts. first signals when a second point, not far one, falls beyond warning limit. additionally point charts are compared with standard and generalized v...

BACKGROUND The inclusion for rehabilitation of visually impaired children is partly based on the measurement of near vision, but guidelines for near visual acuity assessment are currently lacking. The twofold purpose of this systematic review was to: (i) provide an overview of the impact of the chart design on near visual acuity measured, and (ii) determine the method of choice for near vision ...

Absfracl-In this paper, we propose a method for analysis of linear turbo equalization that makes use of extrinsic information transfer (EXIT) charts. Given channel knowledge and a timeinvariant set oi linear equalizer coefficients, evolution of soft information in the soft-input soft-output (SISO) equalizer can be estimated via analytically measuring the mutual inionnation between the transmitt...

Since the earliest days of statistical process control, it has been recognized that it is essential to monitor both mean and variability and to trigger an alarm if either characteristic shows sign of a special cause. It is, however, possible to monitor both mean and variance in a single chart responsive to shifts in either. Traditionally, this has been done by using separate X̄ and S or R charts...

In high quality industrial processes, the control chart is design based on cumulative count of conforming (CCC) items is very useful. In this paper, the performance of CCC-r chart with variable sampling intervals (CCC-rVSI chart) in the presence ofinspectionerrors isinvestigated. The efficiency of CCC-rVSI chart is compared with CCC-r chart with fixed sampling interval (CC...
