In-line monitoring of the thickness distribution of adhesive layers in black textile laminates by hyperspectral imaging

Gabriele Mirschel, +2 more
- 08 May 2019 - 
TL;DR: Near-infrared (NIR) hyperspectral imaging was used for in-line monitoring of thickness and homogeneity of hot melt adhesive layers inside laminates made up of black polyester textiles and reflection spectra were found to correlate with the thickness of the adhesive layersinside the laminate.

The Generalization of Student’s Ratio

Harold Hotelling
- 01 Aug 1931 - 
TL;DR: In this article, the distribution at which Student arrived was obtained in a more rigorous manner in 1925 by R.A. Fisher, who at the same time showed how to extend the application of the distribution beyond the problem of significance of means, which had been its original object, and applied it to examine regression coefficients and other quantities obtained by least squares, testing not only the deviation of a statistic from a hypothetical value but also the difference between two statistics.
