BOLOVAC Systems for Measuring Electrical Quantities From 0.5 MHz Through Microwaves

Description: From Introduction: "This paper describes in some detail how Bolovac works, when its structural components are, what are the methods and steps of the procedure in its various major applications, and reasons for its advantages. The emphasis is on applications. Present status at the National Bureau of Standards relating to fabricating the most important component of the Bolovac-the bolometric disk-is briefly pointed out."

Earthquake Resistance of Earth and Rock-Fill Dams, Report 2: Analysis of Response of Rifle Gap Dam to Project Rulison Underground Nuclear Detonation

Description: Summary: The motion of Rifle Gap Dam was measured in September 1969 during the Project RULISON underground nuclear explosion. The observed response was then compared with the response computed in a mathematical model. Observed and computed responses were similar. From this study it appears that the mathematical models used are applicable to the design and analysis of soil structures, at least for ground motion intensities comparable to those observed at Rifle Gap Dam.
