Measuring Manufacturings Significance in the USA

December 16, 2020
Author(s)
Katherine C. Morris, Douglas S. Thomas
Economic value added is a primary metric for measuring manufacturing activity; however, this metric and others exclude approximately half of the economic activity necessary for producing manufactured goods. With the recent disruption in the supply of goods

Categorization Errors for Data Entry in Maintenance Work-Orders

Analysis of High-Resolution Infrared and N 1 CARS Spectra of 34 S 18 O 3

October 16, 2008
Author(s)
Tony Masiello, J Barber, E T. Chrysostom, J Nibler, A G. Maki, A Weber, Thomas A. Blake, R L. Sams
Three fundamental modes and several hot bands of 34S 18O 3 have been investigated using both infrared spectroscopy and coherent anti-Stokes Raman scattering spectroscopy (CARS). Coriolis coupling effects are particularly noticeable in 34S 18O 3 due to the

Active Vibration-induced PM Noise Control in Optical Fibers: Preliminary Studies

May 29, 2007
Author(s)
David A. Howe, Archita Hati, Craig Nelson, Jennifer A. Taylor, Neil Ashby
Vibration causes mechanical distortions in fiber-optic transmission lines that induce time (phase) fluctuations. RF systems are increasingly using optical fibers in various ways and must occasionally operate in environments with acoustic and structure-born
