This paper proposes a new calculus for expressing the behaviour of object-oriented systems. The semantics of the calculus is given in terms of operators from computational categor...
In this paper, we introduce the systems ns-ACA0 and ns-WKL0 of non-standard second-order arithmetic in which we can formalize non-standard arguments in ACA0 and WKL0, respectively...
Abstract. Graph constraints were introduced in the area of graph transformation, in connection with the notion of (negative) application conditions, as a form to limit the applicab...
In this paper, we recall how the syntax of diagrams is captured by the diagram editor generator DIAGEN, and outline a visual, rule-based, and objectoriented programming language b...
We propose a new implementation scheme for XML transformation languages through derivation of stream processors. Most of XML transformation languages are implemented as tree manipu...
