While Lamb's analysis assumed a straight wavefront, it has been shown [8] that the same characteristic equations apply to cylindrical plate waves (i.e. waves propagating outwards from a line source, the line lying perpendicular to the plate). The difference is that whereas the "carrier" for the straight wavefront is a sinusoid, the "carrier ...
The Lamb Site (11SC24) is an archeological site located in the central Illinois River Valley (CIRV). Excavations of this site began in the 1990s to attempt to understand the Mississippinization of the area following several generations after the intervention of the Cahokians before Columbus's discovery of America. During the eleventh and ...
Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, and are frequently used in non-destructive testing for detecting defects.

Stoneley waves are most commonly generated during borehole sonic logging and vertical seismic profiling.They propagate along the walls of a fluid-filled borehole.They make up a large part of the low-frequency component of the signal from the seismic source and their attenuation is sensitive to fractures and formation permeability.
The free-roaming mind of a Gemini can lead them to hold seemingly contradictory opinions…which can freak out a Scorpio, who needs to know where their partner stands on everything at all times.
Plates with serials 1 through 999 had "ILL-34" at the bottom; plates with serials 1000 through 9999 had "ILLINOIS-34"; and plates with serials 10-000 and up had "ILLINOIS-1934". The latter two groups were the first plates to feature the full state name. 1935 Blue on white with border line; "ILL-35", "ILLINOIS-35" or "ILLINOIS-1935" at top none
