A clinical data system is under development at the Upjohn Company that will reduce the time lag from patient visit to data availability, data entry errors, and the amount of training required for system use. The system design allows generality for bo

Using ray theory and assuming zero offset between source and detector, we have derived an expression for reverberation sequences in two‐dimensional models involving a water layer with a dipping bottom. The operators exhibit novel departures from th

This preliminary theoretical study is basically concerned with the estimation of the depth of an explosive source from a knowledge of the radiated Rayleigh wave. Details are given of the dependence of the amplitude spectrum on the explosive yield, de

The response of a system, consisting of two elastic half spaces in contact at a plane interface, has been investigated for different types of “line sources.” I use the term “line source” to designate a source of elastic energy which has the f

The problem treated is concerned with predicting the transient response of a system composed of a liquid layer, bounded above by a vacuum and below by a perfectly elastic solid, when excited by an arbitrary pressure applied uniformly over the surface

The formal solution for an axially symmetric radiation field in a multilayered, elastic system can be expanded in an infinite series. Each term in the series is associated with a particular raypath. It is shown that in the long‐time limit the indiv

The objective of this work is to provide a method for predicting the surface response of a stratified half space to the radiation from a localized source when neither the assumptions of the plane wave theory nor the assumptions of the normal mode the

The reflected and transmitted waves generated by a plane, monochromatic, compressional wave incident at a plane interface between two half‐spaces are analyzed. Energy ratios and the phase angles for the vertical displacement have been tabulated for
