Automatic Measurement of Network Parameters: A Survey

Description: Report issued by the Bureau of Standards over a survey conducted on measurement methods of network parameters. As stated in the introduction, "this paper is concerned with the development of automatic methods of measuring basically the magnitudes and phase differences, or the complex ratio of two sinusoidal voltages, and applications of this capability to determining complex reflection coefficients and transmission coefficients and group delay times of electrical networks" (p. 1). This report i… more

The First Spectrum of Hafnium (HF I)

Description: Report continuing W. K. Meggers' previous analysis in LS-coupling. This coupling is not rigorous in Hf I, and many intervals are irregular. Consequently, the levels are given also in numerical order with the even and odd levels presented in separate tables. The long line lists are given in two Appendices: Appendix A contains the observed Zeeman data for the individual lines, 531 in all; Appendix B consists of the complete line list of observed and classified lines. By far the greater part of th… more

What About Metric?

Description: Pamphlet issued by the United States National Bureau of Standards discussing the reasons that the U.S. decided passed the Metric Conversion Act of 1975 and provides tables, illustrations, and formulas for converting between customary units and metric units of measuring weight, length, volume, and temperature. It also includes a discussion of how one might expect to use metric measurements in the marketplace, in the home, and at work.
