With the addition of a shared database to a network, users can now centrally store data, find the data again easily, and report on it. The network extends the database to all users who need the information. Information that is changed by one user is instantly updated for all users. As new information is added to the database, all the users can see it. With a modem database, it is important to note that the data contained within the database need not be limited to plain text data. Text, images, documents, video, sound, and any other information that can be entered into a computer can be stored in a database. 

SEM-BSE images document that sample VUT191 11 does show chemical variability at the micrometer scale. Indeed, Figure 43.33A illustrates chemical zoning of crystal VUT191 11 on the sample surface as it was ana-... 

Studies of complex samples are the most demanding tasks in analytical methods and therefore must combine high-resolution separation systems with an equally advanced, selective detector. During the last decades, planar forms of electrophoresis, such as polyacrylamide gel electrophoresis (PAGE) and agarose gel electrophoresis, additionally supported with imaging documentation systems, are very useful tools for separation and identification of the complex biological samples. 

The processing and interpretation of a sequence of images documenting the observed transport of a tagged solute involves several considerations. In most cases the desired output is the fluid velocity, exhibiting a spatial resolution... 

The QAP system additionally was developped for inspection documentation purposes to meet the modern requirements in process documentation (ISO 9000). It is the basic system required to install a fully automated inspection by a camera system and image processing. 

The software US-SCAN 3.0 (IBT GmbH, Ober-Ramstadt, Germany) provides all functions of a portable flaw detector and a powerful ultrasonic imaging in A-, B-, C- and D-scans. Not only motor driven scanners can he used, but also manual scanning systems with encoders. Further documentation and test reports can be carried out with Windows software. 

The principal equipment for the ultrasonic examination is the P-scan system, PS-4, which is a computerised ultrasonic system, developed by FORCE Institute, for automatic, mechanical and manual ultrasonic examination of welds and materials. The system has documentation and storage facilities for all data related to each inspection operation, and includes visualisation of the inspection results in the form of images of the material volume examined. 

The World Patent Index of Derwent Information Ltd. is a broad collection of international value-added patent documents from 40 patent-issuing authorities. The bibliographic database contains 11.6 million patent records with 5.5 million images (October, 2002) and grows by 1.5 million patent documents each year. The classified and indexed documents (since 1963) are sometimes provided wdth additional abstracts or significant titles.

GORE. The CORE Electronic Chemistry Library is a joint project of Cornell University, OCLC (On-line Computer Library Center), Bell Communications Research (Bellcore), and the American Chemical Society. The CORE database will contain the full text of American Chemical Society Journals from 1980, associated information from Chemical Abstracts Service, and selected reference texts. It will provide machine-readable text that can be searched and displayed, graphical representations of equations and figures, and full-page document images. The project will examine the performance obtained by the use of a traditional printed index as compared with a hypertext system (SUPERBOOK) and a document retrieval system (Pixlook) (6,116).

Thermal imaging is sensitive to iafrared radiation that detects temperature changes over the surface of a part when heat has been appHed. Thermal diffusion ia a soHd is affected by variatioa ia composition or by the preseace of cracks, voids, delamiaatioas, etc the effects are detected by surface temperature changes. Defects cannot be detected if their depth below the surface is more than two to three times their diameter. Nondestmctive testing has been primarily used for composites and analysis of adhesive bonds or welds. Several studies are documented ia the Hterature (322—327). 

On a still larger scale, the making of full-size Polacolor repHcas of works of art provides accurate images for display and for professional study and documentation (see Fine art examination and conservation). Because these do not involve photographic reduction and enlargement, the 1 1 repHcas maintain the fine detail and dimensional relationships of the original subjects.
