Time of Flight Ultrasonic Determination of 3D Elastic Constants — The three dimensional elastic constants of materials can be measured using the ultrasonic immersion method. This was pioneered by xx and xx from the National Physical Laboratory in the 19xx s. It has mainly been used for polymer composite… … Wikipedia
Ultrasound — Not to be confused with Supersonic .Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Although this limit varies from person to person, it is approximately 20 kilohertz (20,000 hertz) in healthy,… … Wikipedia
Robert Weber (astronomer) — Robert Weber was an American astronomer who ran the precursor to the LINEAR project shortly before his retirement in 1996. Data were collected by manually entering telescope pointing positions and requesting an image save. Searching twenty fields … Wikipedia
