Automated Measurement of Frequency Response of Frequency-Modulated Generators Using the Bessel Null Method
From abstract: This paper describes a Bessel null technique to measure the frequency response of a frequency-modulated rf carrier and a program to automate frequency response measurements of signal generators with output frequencies from 0.450 to 2000 MHz. The measurements obtained using this technique are more precise than those obtained by a highly trained technician using a manual system.

Possible Estimation Methodologies for Electromagnetic Field Distributions in Complex Environments
Abstract: The problem of measuring and characterizing complicated multiple-source, multiple-frequency electromagnetic environments is becoming more important and more difficult as electrical devices proliferate. This paper outlines three general approaches to the problem which are currently under investigation at the National Bureau of Standards. The three approaches are: 1) a statistical treatment of the spatial distribution of electromagnetic field intensities, 2) a numerical computation using a finite-difference (or lattice) form of the electromagnetic action functional, and 3) use of a directional probe to scan a volume. All three methods are still in the development stage, but each appears promising.

Engineering Report on the McDermitt Caldera Drilling Project: Humboldt County, Nevada, Harney and Malheur Counties, Oregon
Introduction: This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the eleven holes drilled in the McDermitt caldera project during the 1981 drilling program. General information is presented regarding specific problems, including weather and logistics. A separate geologic report is being prepared and will be available through the Bendix Field Engineering Corporation Technical Library in the near future.

[Wyoming Uranium Evaluation] Volume 3: Uranium Assessment for the Precambrian Pebble Conglomerates in Southeastern Wyoming
From introduction: The Geology Department of the University of Wyoming was asked to make a geostatistical assessment of the uranium endowment of these deposits as a part of the World Class core drilling operations of the Bendix Field Engineering Corporation. This study was to include (a) the development of optimum geostatistical methodology for assessing uranium endowment in areas of close drill control (1 mile or less centers) as well as in areas of distant drill control (5 mile centers or more), (.b) the implementation of this methodology in assessing the uranium resources of the pebble conglomerates in southeastern Wyoming, and (c) the determination of the overall geostatistical uncertainty of the resource estimates. In addition, methods were to be studied for projecting the assessments into new areas, including prediction of estimate uncertainty.
