Advancing Manufacturing Quality Control Capabilities Through The Use Of In-Line High-Density Dimensional Data
… measurement devices. Unfortunately, appropriate quality control (QC) techniques have yet to be developed to take full advantage of this new data-rich environment and for the most part rely on extracting discrete key product characteristics (KPCs) for analysis. In order to maximize the potential …

A Fault Classification System for Quality and Productivity Improvement in Continuous Manufacturing Processes
… industry has recognized the need to improve the quality and productivity of its products and processes in order to increase its competitive position. In order to establish a high quality product companies install "quality systems" to improve product and process quality through intelligent …

Intergration of control chart and pattern recognizer for bivariate quality control
… of the existing multivariate statistical process control schemes are only effective in rapid detection but suffer high false alarm. This is referred to as imbalanced performance monitoring. The problem becomes more complicated when dealing with small mean shift particularly in identifying the …

Tests of quantitative precipitation estimates using national weather service dual-polarization radar in Missouri
… has an effect on the error and bias. Various quality control (QC) methods are applied to the radar parameters in order to determine whether or not they enhance the outcomes of the statistical testing applied to the radar data. The results show that R(Z, ZDR) type equations produce the best …

Expanding the genome editing toolbox for biomedical applications
… and precise genome editing. However, a thorough quality control (QC) process for the targeted site following this method has yet to be developed, and as a result, unwanted mutations may go undetected. To this end, we targeted two mouse genes, Ace2 and Foxg1, via CRISPR-READI, and generated three …

Uncovering novel genes causing isolated gonadotropin releasing hormone deficiency using runs of homozygosity in outbred families
… in outbred populations. METHODS: Strict quality control (QC) metrics for the SNP genotyped cohort and controls were used. Overall, 653 European IGD probands and 1,911 European controls remained. After pruning, 206,012 SNPs remained. Runs of Homozygosity (ROH) were found and a burden …

Robust and efficient process for acceptance testing of radiation therapy machines
… testing (AT), commissioning, and ongoing quality assurance (QA) and quality control (QC) of linac and treatment planning systems (TPS) is extremely inefficient requiring substantial labor efforts and significant expense for the testing equipment and software. Despite these efforts and …

Selection of Pathogen Surrogates and Fresh Produce Safety: Implications for Public Health and Irrigation Water Quality Policy
… irrigation water, and evaluate a common industry quality control (QC) E.coli strain (ATCC 25922). Selections of E.coli surrogates were made utilizing biofilm and leaf attachment data from lab scale assays. Five surrogates were found to be similar in biofilm formation and leaf attachment …
