Automatic Indexing: A State-of-the-Art Report

Automatic Indexing: A State-of-the-Art Report

Date: February 1970
Creator: Stevens, Mary Elizabeth
Description: Report issued by the U.S. National Bureau of Standards discussing results of a survey conducted on automatic mechanized indexing and data processing. As stated in the introduction, "it has concentrated on the major developments in and related demonstrations of automatic indexing potentialities. Examples are also given of indexes compiled by machine and of potentially related research efforts in such areas as natural language text searching, statistical association techniques used for search and retrieval, and proposed systems for concept processing" (p. 1).

Date: December 28, 1966
Creator: Love, Carl H.
Description: The abscissas and weights for Gaussian Quadrature of order N = 2 to 100,and N = 125, 150, 175, and 200 are given. The abscissas are given to twenty-four places and the error is estimated to be no more than 1 unit in the last place. The weights are given to twenty-three places and the error is estimated to be no more than 1 unit in the last place.

The Effect of Time Ordering on the Lyman α Profile

The Effect of Time Ordering on the Lyman α Profile

Date: June 1971
Creator: Godgrey, J. T.
Description: Report investigating the effects of time-ordering over the complete line profile using a unified theory of spectral line broadening previously developed. The behavior of the time-ordered thermal average and un-time-ordered thermal average are compared. The Fourier transform of the thermal average is obtained analytically. Calculations for the line profile of the Lyman-[functional symbol alpha] line of hydrogen are presented and are representative in that the full thermal average is replaced by the thermal average with the electron velocity distribution approximated by f(v)=[functional symbol alpha] (v-vav) where vav is the thermal velocity for the plasma in question.

Tensile and Impact Properties of Selected Materials From 20 to 300 ºK

Tensile and Impact Properties of Selected Materials From 20 to 300 ºK

Date: June 28, 1963
Creator: Warren, K. A.
Description: Report giving the tensile and impact properties of structural materials that were experimentally determined at temperatures from 20 to 300 ºK. Tensile properties of a few materials were also determined at 4 ºK. The properties experimentally determined were the yield strength, tensile strength, elongation, and reduction of area, the stress versus strain curve, and the impact energy. The test equipment and procedures are described. The individual data are presented in tables, and the average results are displayed in graphs.
