New algorithms Geolocate a video from its images and sounds (Libraries and Components)
Posted by: Site Administration
Researchers from the Ramón Llull University (Spain) have created a system capable of geolocating videos by comparing their audiovisual content with a worldwide multimedia database. In the future this could help to find people who have gone missing after posting images on social networks, or even to recognise locations of terrorist executions.

Parallel programming may not be so daunting (Libraries and Components)
Posted by: Site Administration
Computer chips have all-but stopped getting faster: The regular performance improvements we’ve come to expect are now the result of chipmakers’ adding more cores, or processing units, to their chips, rather than increasing their clock speed.

Stanford scientists use 'virtual earthquakes' to forecast Los Angeles quake risk (Libraries and Components)
Posted by: Site Administration
Stanford scientists are using weak vibrations generated by the Earth's oceans to produce "virtual earthquakes" that can be used to predict the ground movement and shaking hazard to buildings from real quakes.

The mathematical method for simulating the evolution of the solar system has been improved by UPV/EHU researchers (Libraries and Components)
Posted by: Site Administration
In order to improve a simulation designed to study the evolution of the solar system through time, numerical mathematical methods have been developed at the Computing Faculty of the University of the Basque Country (UPV/EHU). Specifically, the methods proposed enable the simulation calculations to be done faster and more accurately.

3D Printing on the Micrometer Scale (Libraries and Components)
Posted by: Site Administration
At the Photonics West, the leading international fair for photonics taking place in San Francisco (USA) this week, Nanoscribe GmbH, a spin-off of Karlsruhe Institute of Technology (KIT), presents the world’s fastest 3D printer of micro- and nanostructures. With this printer, smallest three-dimensional objects, often smaller than the diameter of a human hair, can be manufactured with minimum time consumption and maximum resolution. The printer is based on a novel laser lithography method.

Gap geometry grasped: A new algorithm could help understand the structure of liquids, and how they flow through porous media (Libraries and Components)
Posted by: Site Administration
Theoretical physicist Moumita Maiti and colleagues at the Jawaharlal Nehru Centre for Advanced Scientific Research in Bangalore, India, have now implemented an algorithm for analysing void space in sphere packing, where the spheres need not all be the same size. This method, about to be published in EPJ E, could be applied to analyse the geometry of liquids present between multi-sized spheres that are akin to a model for porous material. This provides a tool for studying the flow of such fluids through porous material. More importantly, it can also be used to study the packing geometry of proteins.

The advantages of 3D printing are now being put to the test in soil science laboratories (Libraries and Components)
Posted by: Site Administration
Imagine printing a 3-D object as easily as a typed document. Lose a button? Print one. Need a new coffee cup? Print one. While the reality of printing any object on demand may lie in the future, the technology necessary to do it has been available for decades. And soil scientists are now taking advantage of its possibilities.

Preventing 'Cyber Pearl Harbor' (Libraries and Components)
Posted by: Site Administration
Cyber attacks that have long caused major work disruption and theft of private information are becoming more sophisticated with prolonged attacks perpetrated by organized groups. In September 2012, Bank of America, Citibank, the New York Stock Exchange, and other financial institutions were targets of attacks for more than five weeks. Defense Secretary Leon E. Panetta warned that the United States was facing the possibility of a "cyber-Pearl Harbor" and was increasingly vulnerable to foreign computer hackers who could disrupt the government, utility, transportation, and financial networks.
