When the CD at the beginning of the 1980s replaced the vinyl record, the industry believed he had found a storage medium for eternity. Today his that know themselves as smoke and mirrors: German music archive registered, that is the oldest copies begin to decomposed. Therefore, the CD has not to prolong the life of a recording over the 200 years of a record, but drastically reduced to one-sixth. Thus, the durability of the silver disc is equal to the the tape that demagnetized for approximately 30 years. The same applies to video tape and DVD after all: private collectors who build their own music or film archive are hardly noticed the gradual loss of quality of the discs. Because the players can extrapolate the missing digital data from the rest of the track.

More problematic it looks, however, insurance companies and other companies for the archives of authorities, research and cultural enterprises, banks. Almost all of these institutions have their data in reliance on the technology digitized. Now that couldn’t come beforehand on a new medium to copy their data holdings (migrate), for the specific purpose of State of the art”is. Some specialty companies such as IBM deliver robots that continuously check data store and automatically restore in case of defects. This hochproffesionelle version of the backup is a three-digit amount per migrated disc however. Culture archive reflect already on the good old microfilm back but in a contemporary variant: it no longer comes to scan up the originals. Rather, documents, pages and images, such as currently are usual, compressed to a digital record; a laser writes it directly to the film. He is recorded as airtight as a master tape and protected from light; Copies are considered for use. The downside: The archive-laser procedure needs a laser unit. And as the movie that is likely to follow not more than one hundred years.

Halverson & Peschke measuring and testing technology GmbH has passed a universal testing machine of type INSP 100 at the University of Kassel. The new system allows material testing up to 1,200 c. Nossen/Kassel, October 21, 2008 the Halverson & Peschke measuring and testing technology GmbH has passed a universal testing machine of type INSP 100 at the University of Kassel. The new plant is equipped with a high-temperature furnace, which enables material testing up to 1,200 c. To broaden your perception, visit patrick smith. In the framework of a project funded by the German Research Foundation DFG, the Chair of forming technology examines the temperature-dependent inelastic material behaviour of metals and plastics. Here, the Halperin & Peschke GmbH important parameterized data is contribute to the new universal strength testing machine.

INSP 100 determination of mechanical technological properties the universal testing machine of the INSP series with a capacity of 100kN is specially designed for use in material testing laboratories of the metal industry. The Universal strength testing machines are characterised by their high mechanical precision, a superior frame stiffness, as well as the usage of most modern control electronics. Even the basic version offers mounting options for various accessories, such as temperature control chambers, high-temperature furnaces and extensometers. University of Kassel explored coupled phenomena thermo mechanical coupling complex thermal and mechanical mechanisms rarely developed future potential in terms of the design space is just in the context of modern industrial manufacturing processes,\”explained Dipl.-ing. Manuel may wreath Valentin, researcher at the Institute of forming technology of the University of Kassel. The research goal of the special research area Transregio 30 since mid-2006 by the DFG-funded (SFB TR / TRR30) integrated manufacturing of functionally graded structures based on coupled thermo mechanical phenomena ‘ is about new hybrid thermo mechanical process for such micro- and to reach with conventional litigation strategies previously not macro-structural product structures or are only available at uneconomic terms.
