62. On-Line Process Control
Published: Date unknown
Authors: Raghu N Kacker, Nien F Zhang
Abstract: The natural state of manufacturing and measurement processes is usually nonstationary. The methods of statistical process control (SPC) are therefore inappropriate for on-line control. This paper provides a simple and generic protocol for on-line c ...

63. SRM 1955, Homocysteine and Folate in Human Serum; Production of a New Standard Reference Material
Published: Date unknown
Authors: Mary B Satterfield, B C Nelson, Lorna Tregoning Sniegoski, Adriana Hornikova, Nien F Zhang, Christine M Pfeiffer, Michael James Welch
Abstract: Homocysteine (HCY) and folate are interrelated biomarkers for arteriosclerosis and coronary heart disease with health problems associated with increased levels of homocysteine and low levels of folate. Although many different tests for both HCY and f ...

64. Statistical Analysis on Uncertainty for Autocorrelated Measurements
Published: Date unknown
Author: Nien F Zhang
Abstract: When repeated measurements are autocorrelated, it is inappropriate to use the traditional approach to calculate the uncertainty of the average of the measurements, which assumes that the measurements are statistically independent. In this paper, we p ...
