CLASSIC: a structural data model for objects
1989
Proceedings of the 1989 ACM SIGMOD international conference on Management of data - SIGMOD '89
classic is a data model that encourages the description o f o b j e cts not only in terms of their relations to other known objects, but in terms of a level of intensional structurea sw ell. ...
One of the strengths of the approach is that the same language plays multiple roles in the processes of de ning and populating the DB, as well as querying and answering. classic for which w e h a ve a ...

A salient feature here is the graphical calculus for categorical quantum mechanics, which allows a purely diagrammatic representation of classical-quantum interaction. ...

This variation for at least some of these objects has been shown to be due to nonradial pulsation. For at least one star, evidence for a magnetic field has been observed. ...
Recent results for classical Be stars are reviewed and links to general astrophysics are presented. ...
McDavid et al. (2000) , modeling polarimetric data, required a spiral structure, rather than a plainly radial "arm," to explain phase lags in 48 Lib between Ha observations (scanning the outer parts of ...
