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 growing importance of publishing art collections online has led to increasingly strict tolerances on digital photography objects. There are two internationally recognized sets guidelines for creating high-quality images, Metamorfoze and FADGI. These require using standardized color patches in museal photography. X-Rite ColorChecker SG chart with 140 is often used. Recent studies sh...

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...

control chart is the most well-known chart to monitor the number of nonconformities per inspection unit where each sample consists of constant size. generally, the design of a control chart requires determination of sample size, sampling interval, and control limits width. optimally selecting these parameters depends on several process parameters, which have been considered from statistical and...

Background The most common cause of death during neonatal period is prematurity. Nutritional tolerance is very important in this period. If during this period the problems of feeding the preterm infant are not resolved, chronic disorder occurs in normal growth. Materials and Methods In this randomized controlledclinical trial we selected 60 preterm infants in the neonatal intensive care unit...
