For the ?rst time 4 workshops were held along with the eighth Object-Oriented info platforms convention, OOIS 2002, to motivate - teraction among researchers and practitioners. Workshop subject matters are, after all, inline with the conference’s scienti?c scope and supply a discussion board for teams of researchers and practitioners to satisfy jointly extra heavily and to switch evaluations and complex principles, and to proportion initial effects on centred matters in an environment that fosters interplay and challenge fixing. The convention hosted 4 one-day workshops. The 4 chosen workshops have been absolutely within the spirit of a workshop consultation hosted via a primary convention. certainly, OOIS offers with the entire themes concerning using object-oriented ideas for the advance of data structures. The 4 workshops are very speci?c and give a contribution to enlarging the spectrum of the extra normal issues handled frequently convention. The ?rst workshop concerned about a truly speci?c and key c- cept of object-oriented improvement, the specialization/generalization hierarchy. the second explored using “non-traditional” techniques (at the sting of object-oriented ideas, corresponding to elements, AI, etc.) to enhance reuse. The 3rd workshop handled optimization in Web-based details structures. And ?nally the fourth workshop investigated matters on the topic of model-driven software program development.

This ebook constitutes the completely refereed post-proceedings of the 4th overseas info Hiding Workshop, IHW 2001, held in Pittsburgh, PA, united states, in April 2001. The 29 revised complete papers offered have been rigorously chosen in the course of rounds of reviewing and revision. All present matters in details hiding are addressed together with watermarking and fingerprinting of digitial audio, nonetheless picture and video; nameless communications; steganography and subliminal channels; covert channels; and database inference channels.

Sample text

Subclasses are mutually disjoint. This is because the classification is made with regard to an essential characteristic, and it is impossible for an essential characteristic of an object to have two different values simultaneously. For example, a mammal cannot be simultaneously a human and a bovine (see figure 1(b)), because it cannot belong to more than one specie. Rule 3. Object migration is not allowed, because if the essential feature is changed, the object will not be the same. In our example, a human cannot become a cow.

In Sect. 3 we emphasize on polymorphic consideration as the guiding motivation to introduce spec/gen. Section 4 elaborates the rule of strengthening and gives some very powerful uses. In Sect. e. to use complete and disjoint specializations. In Sect. 6 this is extended to multiple spec/gen. The discussion is inspired by the EROOS method [15,13]. While EROOS offers its own notation, which is tailored to the concepts and principles of the method, we elaborate this paper using the Unified Modeling Language (UML) [12].

We shall therefore also have to define an arbitrary group of states. The chosen state, as is the case with the role and the essential characteristic, will depend on the universe of discourse.
