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...

abstract background: menthol is the most important active material in mint and different mechanisms have been suggested for the way mint functions, most of which emphasize its analgesic effect owing to the presence of a group of temporary protein receptors. this study investigates the efficacy of peppermint capsule in the treatment of primary dysmenorrhea, in comparison with mefenamic acid and ...

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...

quality control plays an important role in increasing the product quality. fuzzy control charts are more sensitive than shewhart control chart. hence, the correct use of fuzzy control chart leads to producing better-quality products. this area is complex because it involves a large scope of industries, and information is not well organized. in this research, we provide a literature review of th...

introduction: recent anti-inflammatory group of medications include the introduction of cyclooxygenase-ii inhibitors such as coxibs. these agents offer potentially significant advantages because of their realive lack of gastrointestinal irritation. the aim of this study was to evaluate the effect third molar surgery. methods and materials: this study was a double, randomized, cross over, clinic...
