E-government applications have to archive data or documents for long retention periods of 100 years or more. This requires to store digital data on stable media, and to ensure that the file formats can be read by available software. Both applications as well as media technology have only short life spans. Thus, data has to be migrated at frequent intervals onto new data carriers and to new file...

The chemical pathology requests on 180 000 patients a year are stored on microfiche, occupying 72 mm of shelf space. They are produced by a sequence of three computer programs which remove data from disc on to magnetic tape using the laboratory's Digital Equipment Corporation PDP 11/34 minicomputer. Processing on to microfiche is performed by a bureau. The magnetic tape is available for retrosp...

Observations of rain cells in the remains of a decaying tropical storm were made by Airborne Microwave Radiometers at 19.35, 92 and three frequencies near 183 GHz. Extremely loK^ brightnesa temperatures, as low as 140 °K were noted in the 92 and 183 GHz observations. These can be accounted for by the ice often associated with raindrop formation. Further, the 183 GHz obaervationa can ^.. interpr...

Using data collected by the Voyager 1 and 2 spacecraft in 19801 and 1981. strong evidence is presented for a direct correlation between variations in the solar wind at Saturn and the level of activity of Saturn's nonthermal radio emission. Correlation coefficients of 57-58% are reached at lag times of U-1 days between the arrival at Saturn of high pressure solar wind streams and the onset of in...
