However, most of these data models are restricted to the description of the static structure of a database. They do not provide means to specify the dynamic behaviour of a database. This paper sketches a language for the specification of actions on databases which have been specified by an Extended Entity-Relationship (EER) schema. These actions are based on so-called elementary actions, which are automatically be derived from the EER schema. So, it can always be guaranteed that these schema dependent elementary actions preserve all inherent integrity constraints. The semantics of the elementary actions is given in two steps: First, it is shown how the semantics of a database schema, i.e., a current database state, can be represented by an attributed graph. Then, the semantics of elementary actions is given by programmed graph replacements.}}, author = {{Engels, Gregor}}, booktitle = {{Proceedings of the workshop on Graph Grammars and Their Application to Computer Science (1990), Bremen (Germany)}}, pages = {{344--362}}, publisher = {{Springer}}, title = {{{Elementary Actions on an Extended Entity-Relationship Database}}}, doi = {{http://dx.doi.org/10.1007/BFb0017372}}, volume = {{532}}, year = {{1990}}, } @inbook{16738, author = {{Dietzfelbinger, Martin and Meyer auf der Heide, Friedhelm}}, booktitle = {{Automata, Languages and Programming}}, isbn = {{3540528261}}, title = {{{A new universal class of hash functions and dynamic hashing in real time}}}, doi = {{10.1007/bfb0032018}}, year = {{1990}}, } @inbook{16739, author = {{Meyer auf der Heide, Friedhelm}}, booktitle = {{Lecture Notes in Computer Science}}, isbn = {{3540529535}}, title = {{{Dynamic hashing strategies}}}, doi = {{10.1007/bfb0029597}}, year = {{1990}}, } @inbook{16740, author = {{Karpinski, Marek and Meyer auf der Heide, Friedhelm}}, booktitle = {{Lecture Notes in Computer Science}}, isbn = {{3540529535}}, title = {{{On the complexity of genuinely polynomial computation}}}, doi = {{10.1007/bfb0029630}}, year = {{1990}}, } @inproceedings{16741, author = {{Dietzfelbinger, M. and Meyer auf der Heide, Friedhelm}}, booktitle = {{Proceedings of the twenty-second annual ACM symposium on Theory of computing - STOC '90}}, isbn = {{0897913612}}, title = {{{How to distribute a dictionary in a complete network}}}, doi = {{10.1145/100216.100229}}, year = {{1990}}, } @inproceedings{16742, author = {{Gil, J. and Meyer auf der Heide, Friedhelm and Wigderson, A.}}, booktitle = {{Proceedings of the twenty-second annual ACM symposium on Theory of computing - STOC '90}}, isbn = {{0897913612}}, title = {{{Not all keys can be hashed in constant time}}}, doi = {{10.1145/100216.100247}}, year = {{1990}}, } @article{16824, author = {{Meyer auf der Heide, Friedhelm}}, journal = {{Informatik Spektrum}}, number = {{4}}, pages = {{231--232}}, title = {{{Das Heinz Nixdorf-Institut der Universität-GH Paderborn}}}, volume = {{13}}, year = {{1990}}, } @inproceedings{16913, author = {{Domik, Gitta and Brugel, E.W. and Stencel, R.E.}}, booktitle = {{Proceedings of the 176th meeting of the American Astronomical Society}}, number = {{No. 2}}, title = {{{IRAS On-Line Catalogs at CASA}}}, volume = {{Vol. 22}}, year = {{1990}}, } @article{17164, author = {{Fuchssteiner, Benno and Oevel, Gudrun}}, journal = {{Appl.

Exploiting the polarity of the transitions, a detection window that has double the size of the code bit period is possible. The authors describe a detection circuit that achieves the enlarged detection window, and present a phase detector which is particularly simple to implement. Channel bit-error-rate measurements have been carried out employing a rate 1/3 (2, 8, 2) code. Error rates of 10/sup -8/ were achieved for recording densities up to 33 kb/in.
