Analysis of thermal fluctuations in the Westinghouse Canada Water Loop to determine flow transit delay times using a transfer function cross-correlation technique

Description: Aerojet Nuclear Company performed an experiment at the Westinghouse Canada Ltd. water loop to try to verify the performance of a Transit Time Flowmeter to ultimately measure two-phase flow rates. The recorded data from that experiment were made available and analyzed at Argonne National Laboratory using a transfer function cross-correlation technique. The theoretical background for the transfer function method of analysis and the results of the data analysis are presented. Strong correlation pe… more

Temperature Distributions in Electron Beam Welding Cavities

Description: Surface temperatures in electron beam welding cavities in stainless steel 304 and aluminum 1100, 2024, and 6061 were measured with a narrow band infrared radiation pyrometer. A special device was designed for mounting the radiation-sensing probe next to the electron beam gun in the welding chamber. This mounting device included a mechanism for oscillating the probe so as to scan the cavity region both perpendicular and parallel to the welding direction. At the center of its movement the probe v… more

Relating spatial distributions of pollutants to health effects. Technical report No. 1. [Relation of air pollution to epidemics of respiratory diseases]

Description: A new and potentially useful statistical tool for epidemiology is introduced and some of its elementary properties are considered. The technique is a promising one for both data-analytic and inferential problems. Starting with the collection of isopleths of a spatially distributed explanatory variable (air pollution), the method produces a relationship between the explanatory variable(s) and the response variable (population-adjusted health effects) by accumulating the response within successiv… more

Multivariate Ornstein--Uhlenbeck process in studies of home range. Technical report No. 2. [Radiotelemetry tracking of birds, deer, and coyotes]

Description: In home range studies, the statistical analysis of radio telemetry data poses special problems due to lack of independence of successive observations along the sample path. Assuming, however, that such data is generated by a continuous, stationary, Gaussian process possessing the Markov property, then a multivariate Ornstein-Uhlenbeck diffusion process is necessarily the source and is proposed here to be a workable model. Its characterization is given in terms of the typical descriptive propert… more

Kinetics and mechanism of desulfurization and denitrogenation of coal-derived liquids. Fourth quarterly report, March 20--June 20, 1976

Description: The high-pressure liquid-phase flow microreactors are operating satisfactorily in both hydrodesulfurization and hydrodenitrogenation studies after minor modifications to allow in situ sulfiding. The hydrodesulfurization of dibenzothiophene occurs by a simple network giving only H/sub 2/S and biphenyl as primary reaction products. The reaction network for quinoline hydrodenitrogenation has been determined, and a kinetic model developed to allow quantitative determination of the first-order kinet… more

Irradiation effects on the mechanical properties of zirconium and dilute zirconium alloys: a review

Description: The effects of fast flux (E greater than or equal to 1 MeV) neutrons on zirconium and dilute zirconium alloys are discussed. The effects on the elastic constants, strength and ductility, creep, fatigue and fracture, and irradiation growth are reviewed. (FS)
