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...

The authors are to be congratulated for a very important contribution with many practical applications. Including covariates in the construction of growth charts will undoubtedly lead to more informative tools for practitioners in many disciplines. Growth charts are widely used in practice to monitor the evolution of particular univariate measurements over time. In some situations, a patient’s ...

International research suggests that differences in teacher performance can explain a large portion of student achievement. Yet little is known about how the quality of the Australian teaching profession has changed over time. Using consistent data on the academic aptitude of new teachers, we compare those who have entered the teaching profession in Australia over the past two decades. We find ...

Suppose that a target function f0 : R d → R is monotonic, namely, weakly increasing, and an original estimate f̂ of this target function is available, which is not weakly increasing. Many common estimation methods used in statistics produce such estimates f̂ . We show that these estimates can always be improved with no harm using rearrangement techniques: The rearrangement methods, univariate and...


 A few years ago, validating proteins to see if they were good or bad was a process that took years. With the creation of Ramachandran Graph evaluates protein structures through angles φ (phi) and ψ (psi), this task became less onerous. evolution computing bioinformatics, platforms have been created generate graphs in an online manner, however, high degree usability complexity. The system...
