The raw scanned image files were processed by using data normalization, quality assurance and control, filtering, and clustering.
For spot finding and generating preliminary result files the raw scanned image files were analyzed using GenePixPro version 6.0 whereas data normalization, quality assurance and control, filtering and clustering were carried out with GeneTraffic (Iobion, Agilent, Waldbronn, Germany) and statistical analysis with the SAM-program package.
On the other hand, MODIS NDVI is produced from atmospherically corrected surface-gridded reflectance with per pixel quality assurance information that is cloud filtered (Huete et al. 2011).
For quality assurance, 12 field blank filters and 19 duplicate measurements also were collected.
Other critical issues that add to the computational burden are: data interface with a limited bandwidth, the frequency of updating of data during a pandemic progress, pre-processing (filtering and quality assurance) requirement for raw data, and the need for data translation into parameter values using methods, like maximum likelihood estimation and other arithmetic conversions.
However it is not freely available to clinical centres and it does not try to improve broader clinical aspects such as detailed quality assurance reports, robustness, reports and specialised variant filtering.
On COBWEB, part of this quality assurance is done by automatic filters on the data collected, based on known statistic distributions.
But isn't peer review supposed to be the quality assurance mechanism for research, an essential filter that prevents flawed or nonsensical papers from being published?
The U.S. EPA has conducted a quality assurance study of laboratories handling STN filter samples and the results indicate that, although there was some variability between laboratories (particularly for lower mass components, such as aluminum and sodium, and for specific subfractions of OCM), there was general consistency between the laboratories for most PM2.5 components (U.S. EPA 2005).
Quality assurance and quality control methods from the National Oceanic and Atmospheric Administration NOAA Meteorological Assimilation Data Ingest SystemeMADISDIS) were used to filter out data that may have resulted from sensor drift or spiking (http://madis.noaa.gov/madis_qc.html).noaa.gov/madis_qc.html
For all chemical and physical analyses in the laboratory, field blanks, filter-lot blanks, replicate analyses, and externally certified standards were incorporated for quality assurance and quality control purposes.
