Optimization is an effective method for enhancing the crashworthiness of cars. In a series of simulations of crash tests at Linköping University in Sweden it was possible to reduce the penetration of passenger space by a third.
Every year 47,000 people are killed in automobile accidents in the EU. This is as if a jumbo jet were to crash every third day. Such horrendous figures cry out for ever greater investments in crashworthiness. Modern optimization technique, based on so-called finite element methods, can bring us safer cars at a considerably lower cost of development.
A study carried out at the Linköping University Division of Solid Mechanics in collaboration with SAAB Automobile AB shows that it is possible to cut calculation times to one fourth of the time using traditional optimization methods. In his doctoral dissertation, Marcus Redhe describes 26 assessments that he carried out on a collision model of a SAAB 9-3. The optimization technique he used is called Space Mapping. The basis for calculations was a crash test of an American model in which the car was driven straight into a steel barrier at 56 km/h.

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...
