The next time the New Madrid fault zone produces a strong earthquake, buildings in the Midwest may see less damage if they use a new device developed by a researcher at the University of Missouri-Rolla.
Dr. Genda Chen, associate professor of civil engineering at UMR, has spent the past five years developing a “smart” damper that can adapt to external disturbances such as earthquakes and keep buildings from shaking as much. His most recent findings are included in an upcoming issue of the Journal of Structural Control and Health Monitoring, available Sept. 12. Earlier findings were reported in the March 2004 issue of the International Journal of Structural Engineering and Mechanics and the April 2004 issue of the American Society of Civil Engineers’ Journal of Engineering Mechanics.
Chen’s damper operates much like the brakes of an automobile. “When you drive and go too fast, you press the brake to slow down a little bit,” Chen explains. “Then you release the brake so you can keep your speed in a comfortable range. We’re using the same concept for a building. If, during an earthquake, the building shakes too much, we would like to brake it using a friction device.”

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
