An Analytical Model for Predicting Cross-Country Vehicle Performance, Appendix D: Performance of Amphibious Vehicles in the Water-Land Interface (Hydrologic Geometry)

Description: Summary: "Forty tests were conducted with two amphibious tracked vehicles and one amphibious wheeled vehicle at Eglin Air Force Base, Fla., and near Khon Kaen, Thailand, to determine the vehicles' capabilities for exiting closed bodies of water. Empirical relations, based on the data collected in this study and in previous studies, are presented to support the conclusions that performance of amphibious tracked and wheeled vehicles (in terms of "go-no go") in the water-land interface can be correlated with soil strength (expressed as average cone index of the 0- to 6-in. soil layer), and that the slope-climbing ability in the water-land interface of the tracked vehicles tested compares favorably with that of the same vehicles operating on land surfaces of similar soil composition and consistency" (p. ix).

The Calculation of Rotational Energy Levels and Rotational Line Intensities in Diatomic Molecules

Description: Report describing procedures for making quantum mechanical calculations of rotational energy levels and rotational line intensities in diatomic molecules. The procedures are illustrated by sample calculations. A familiarity with the material of this report should enable a practicing electronic spectroscropist to carry out, though in a rather mechanical way, his own theoretical calculations for molecules under experimental investigation.
