41Cosmic microwave background experiments — [ Cosmic background (CMB) temperature on the celestial sphere as determined with the COBE satellite, (top) uncorrected, (middle) corrected for the dipole term due to our peculiar velocity, (bottom) corrected for contributions from the dipole term …
42Ontology-based data integration — involves the use of ontology(s) to effectively combine data and/or information from multiple heterogeneous sources [1]. It is one of the multiple data integration approaches and may be classified as Local As View (LAV)[2]. The effectiveness of… …
43National Space Science Data Center — The National Space Science Data Center serves as the permanent archive for NASA space science mission data. Space science pertains to astronomy and astrophysics, solar and space plasma physics, and planetary and lunar science. As the permanent… …

49Control Data Corporation — (CDC) was a supercomputer firm. For most of the 1960s, it built the fastest computers in the world by far, only losing that crown in the 1970s after Seymour Cray left the company to found Cray Research, Inc. (CRI). CDC was one of the nine major… …
50Cosmic infrared background — (CIB) is a mysterious infrared light coming from outer space. It is slowly being resolved into specific sources by infrared telescopes. In some ways it is analogous to the cosmic microwave background, but at shorter wavelengths. Contents 1… …
