Ivan A. Getting synchrotron at MIT Radiation Laboratory. He also was involved in the development of the Sparrow III and Hawk missile systems; as well as commercial production of transistors at Raytheon. As a consultant to the US government: implementation of the Quick Reaction Capability for Electronic Counter-Measures; establishment of the SHAPE Supreme Headquarters Allied Powers Europe Laboratory at the Hague; deployment of U.S. air defense capability called the Semi-Automatic Ground Environment (SAGE) radar system; direction of studies on MX missile basing and long-range combat aircraft; technical analysis and design of a long-range supersonic bomber capable of reaching the former Soviet Union and
Seismic refraction velocity of the first layer V - velocity of the second layer h - thickness of the first layer T0 - intercept Seismic refraction Seismic refraction is a geophysical principle (see refraction) governed by Snell's Law. Used in the fields of engineering geology, geotechnical engineering and exploration geophysics, seismic refraction traverses (seismic lines) are performed using a seismograph(s) and/or geophone(s), in an array and an energy source. The seismic refraction method utilizes the refraction of seismic waves on geologic layers and rock/soil units in order to characterize the subsurface geologic conditions and geologic structure. The methods depend on the fact
