The worlds particle physics community today announced the launch of the first phase of the LHC computing Grid (LCG). The LCG is designed to handle the unprecedented quantities of data that will be produced by experiments at CERN ’s Large Hadron Collider (LHC) from 2007 onwards. "The LCG will provide a vital test-bed for the new Grid computing technologies that are set to revolutionise the way scientists use the worlds computing resources in areas ranging from fundamental research to medical diagnosis," said Les Robertson, CERNs LCG project manager.
The computational requirements of the experiments that will operate at the LHC are enormous. Some 12-14 petabytes of data will be generated each year, the equivalent of more than 20 million CDs. Analysing this data will require the equivalent of 70,000 of todays fastest PC computers. The LCG will meet these needs by deploying a worldwide computational Grid, integrating the resources of scientific computing centres spread across Europe, America and Asia into a global virtual computing service.
The first phase of the project, LCG-1, will operate a series of prototype services, gradually increasing in scale and complexity as its builders develop an understanding of the functional and operational complexities involved in building a Grid of such unprecedented scale. LCG-1 uses so-called "middleware" developed mainly by the European Data Grid project in Europe and the Globus, Condor and related projects contributing to the Virtual Data Toolkit in the US. It allows physicists to access worldwide distributed computing resources from their desktops as if they were local.

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
