Today, humans perform visual inspections every two years of most of the nation's older bridges. But with a scarcity of inspectors and tens of thousands of bridges, that process can be long and laborious. http://www.physorg.com/news159116064.html Technology Thu, 16 Apr 2009 15:55:04 EST news159116064 Virginia Tech's Center for Intelligent Material Systems and Structures (CIMSS) has teamed with Physical Acoustics Corporation (PAC), of Princeton Junction, N.J., to develop a suite of new technologies to provide a continuous, energy independent monitoring of the structural integrity of U.S. bridges. http://www.physorg.com/news152795925.html Technology Mon, 02 Feb 2009 11:19:15 EST news152795925 Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights. However, detecting them isn't so easy. http://www.physorg.com/news134322564.html Nanotechnology Thu, 03 Jul 2008 16:49:24 EST news134322564
