81. Micro-NCT of the Tool-Chip Interface in Machining
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6572
Published: 1/1/2000
Authors: Timothy J Burns, Matthew A. Davies, Michael Kennedy, Howard W Yoon
Abstract: Machining is a ubiquitous manufacturing process with tremendous economic impact. For example, Dr. Eugene Merchant, who is a founder of the scientific treatment fo machining processes, recently estimated that approximately 15 % of the value of all man ...

82. NIST-PTB Measurements of the Radiometric Temperatures of a High-Temperature Black Body Using Filter Radiometers
Published: 1/1/2000
Authors: Howard W Yoon, P Sperfeld, S Galal Yousef, J Metzdorf
Abstract: The results of a bilateral intercomparison of radiometric temperatures of a high-temperature blackbody from 2100 K to 3100 K measured using filter radiometers are described. The measurements took place over a ten-day period in October 1998 at the PT ...

85. Radiometric Measurement Comparisons Using Transfer Radiometers in Support of the Calibration of NASA's Earth Observing System (EOS) Sensors
Published: 9/1/1999
Authors: James J. Butler, Bettye C Johnson, Steven W Brown, Howard W Yoon, R Barnes, B L Markham, S F Biggar, E F Zalewski, P R Spyak, J W Cooper, F Sakuma
Abstract: EOS satellite instruments operating in the visible through the shortwave infrared wavelength regions (from 0.4 um to 2.5 um) are calibrated prior to flight for radiance using integrating spheres at a number of instrument builder facilities. The trac ...

87. Determination of Radiance Temperatures Using Detectors Calibrated for Absolute Spectral Power Response
Published: 6/1/1999
Authors: Howard W Yoon, Charles E Gibson
Abstract: We describe a method of directly determining blackbody radiance temperatures using filter detectors calibrated for absolute spectral power responsivity. The calibrations for absolute power are derived from a highly-accurate cryogenic radiometer, an ...
