Digital Memory

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.

Nexans Germany

The year’s 45th national competition is the Foundation “youth research” out e.V. together with ThyssenKrupp AG from 13 to 15 May 2009 in Essen. We are committed to youth research, because we want to help the youth to realize their own future with its technical possibilities. Together with the youth of today, we develop the future it – our children – are living in the”Dr. Francis Krahenbuhl, Chief Executive Officer of Nexans Germany GmbH.

our support of the youth research dash is just one example, the early contact with schools and universities is as important to us. Finally we want to present as early as possible ourselves as an attractive employer our future employees”, adds Jutta van, spokeswoman Nexans Germany. That education is not a product, but rather an ongoing process, proves also the cable expert his national and international continuing education programs such as leadership development and the Nexans University”. Photo caption: The youth discovered new worlds the official poster of youth research 2010. About 5,000 research projects in the areas of workplace, biology, chemistry, Earth and space sciences, mathematics/computer science, physics and technology are for the competition Jugend forscht 2010 has been filed. Nexans Germany of Nexans Germany is one of the leading cable manufacturers in Europe.

The company offers a comprehensive range of high-performance cables, systems and components for the telecommunications and energy sectors. The programme is rounded off by superconducting materials and components, Cryoflex transfer systems and special machines for the cable industry. It is made in Germany and abroad with approx. 6.240 employees. The turnover is approx. EUR 936 million in 2008. Through the tight integration of the Nexans group Nexans Germany has excellent opportunities for the synergies in all areas of the group. The same is true for global projects as well as for research and development, exchange of know-how, etc.

IBM Research Density

Such technologies are necessary to keep pace with the explosion of digital information”, says Evangelos Eleftheriou, IBM Fellow and Director of storage technology research at IBM Research Zurich. IBM is in a unique position to assist customers in the backup, storage, and analysis of rapidly growing volumes of data and to help them to improve their efficiency and profitability.” Because: long-term storage has become an absolute must for users at relatively low cost. Data are often in automated tape libraries tape recorded, in which a or some a few tape drives manage dozens to thousands of tapes. Tape libraries can now petabytes of data include representing millions of gigabytes. An examination of the cost per gigabyte shows that the costs for the long term storage of data on tape-based systems, Depending on their size, currently are one-fifth to one-tenth of today’s disk storage systems. In addition, tape cartridges cause no power consumption, as long as not they accessed, in contrast to the continuously rotating disks. This offers further potential for cost savings and make the most energy efficient off-the-shelf storage technology tape systems. The current density demonstration is based on several important technical improvements.

25 times more data tracks on the unchanged 0.5 inch wide band could be accommodated through a precise positioning of the read and write heads. A great progress was also made in the detection ability of the individual bits, which allowed a 50 percent increase of the linear density. Another crucial factor was the use of a new, low-friction read and stylus. Almaden, this was developed research at IBM, based on close cooperation with FUJIFILM in the development of new storage media. IBM has had a long Tradition of innovation in tape storage technology. The first commercial IBM tape storage product, the IBM 726 magnetic tape unit was announced about 60 years ago. It also used band roles with a range of about a half an inch, reaching a capacity of approximately 2 megabytes.

Today announced band storage density would correspond to the 17.5 millions capacity of this first band role. (1) the record density was achieved at a typical speed of 2 meters per second, and the obtained error rates are correctable with standard error correction method and meet IBM’s specifications for LTO 4 products. (2) at this calculation, a 12-percent increase in the length of the band adopted the reduced Strip thickness from the results. 3) rounded up from 43.75 further information please refer to the English-speaking media release: news /… You can download high-resolution images online: photos/ibm.

What Is The Rubber?

Rubber as a universal material rubber is a heavily destructible and elastic very resistant fabric. The main ingredient is rubber. This substance is extracted from the Kautschikbaum and was the best for the production of rubber. Rubber is versatile and nowadays hardly to think away from everyday life. Rubber rings are used, for example, as seals for valves o.a.

and one can find it everywhere. The rubber is processed using much pressure and heat to rubber. The result is a long rubber band which is then cut into pieces. A large part of the produced rubber ends up ultimately in Tyre production. Be there to handle different types of rubber and the different rubber bands are then pressed together to the tread of the tyre. Unfortunately, rubber is not unlimited can be, because rubber rings or erasers after some time become brittle and may break eventually. If the rubber is too old, it is no longer elastic and thus loses the characteristics of the material.

Rubber will soften under the influence of heat and finally liquid. In this manner, for example round shapes can be cast. Rubber is very resilient and flexible, but when a parent suspects the substance can tear or burst like the balloon. If the material is stretched such as during a long rubber band in the gym, it shrinks back after relieving on the output size. Rubber is a substance which is no longer indispensable in our industry. There are sealing our window or car tires, everywhere we find this material in the various versions. You could continue the uses for rubber in an endlessly long list here.
