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...

New methods for the assessment of drawing strategies are examined that focus on analysis perceptual chunking. The demonstrated with four diverse participants as they copied a line-graph and bar-chart. Video recordings transcriptions were analysed stroke by stroke. Diverse global used line graph whereas all similar approach bar-chart, but local differences. Performance fluency varied substantial...

The fractional Fourier transform is a mathematical operation that generalizes the well-known Fourier transform. This operation has been shown to have physical and optical fundamental meanings, and it has been experimentally implemented by relatively simple optical setups. Based on the fractional Fourier-transform operation, a new space-frequency chart definition is introduced. By the applicatio...


 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...

to facilitate a comprehensive whole population visual acuity screening, a 1-meter vision screener “e” chart was prepared to be used in the person-by-person household visual acuity examination by non-expert health workers. the chart is designed to be used in measuring visual acuity from a distance of one meter. the scaling is in terms of-log mar (logarithm of minimum angle of resolution) with a ...

This report describes the historical development in the clinical application of chemical variables for the interpretation of acid-base disturbances. The pH concept was already introduced in 1909. Following World War II, disagreements concerning the definition of acids and bases occurred, and since then two strategies have been competing. Danish scientists in 1923 defined an acid as a substance ...
