Digital obsolescence is the risk of data loss because of inabilities to access digital assets, due to the hardware or software required for information retrieval being repeatedly replaced by newer devices and systems, resulting in increasingly incompatible formats.
A particularly important area of system interoperability is CRIS/IR interoperability, [7] i.e. the information exchange workflows between Current Research Information Systems and Institutional Repositories. While these two kinds of systems were once seen as competing with each other, nowadays they tend to work together via efficient mechanisms ...
Time domain statistical multiplexing (packet mode communication) is similar to time-division multiplexing (TDM), except that, rather than assigning a data stream to the same recurrent time slot in every TDM, each data stream is assigned time slots (of fixed length) or data frames (of variable lengths) that often appear to be scheduled in a randomized order, and experience varying delay (while ...
Communication Research Reports is a quarterly peer-reviewed academic journal covering communication studies. It was established in 1984 and is published by Routledge . The journal specializes in the publication of reports-style manuscripts using social scientific methods (such as quantitative data analysis).
TDRS Program Logo Location of TDRS as of March 2019 An unflown TDRS on display at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.. The U.S. Tracking and Data Relay Satellite System (TDRSS, pronounced "T-driss") is a network of American communications satellites (each called a tracking and data relay satellite, TDRS) and ground stations used by NASA for space communications.
The Mortality Medical Data System (MMDS) is used to automate the entry, classification, and retrieval of cause-of-death information reported on death certificates throughout the United States and in many other countries. The National Center for Health Statistics (NCHS) began the system's development in 1967.
In 2002, US Congress appropriated funding for the system for the first time. [2] and the system was established that year. [4] The NVDRS began collecting data in 2003 from six states, a number that increased to 17 by 2006 [2] and 32 by 2016. [5] In November 2008, the system and its accompanying data became freely accessible online. [6]
