Parallel Graph Transformation Applied to AGG Tool
Graph transformation is one of the key concepts in graph grammar. In order to accelerate the graph transformation, the concept of parallel graph transformation has been proposed by different tools such as AGG tool. The theory of parallel graph transformation used by AGG just allows clarifying the concepts of conflict and dependency between the transformation rules. This work proposes an approac...
متن کاملRealizing UML Metamodel Transformations with AGG
In this paper, we work out equivalence transformations on the UML metamodel as concrete graph transformations implemented in the AGG tool. We consider two examples for manipulating the static structure of a UML model, namely the transformation of an association class into a ternary association and the transformation of a ternary association into three binary associations. We discuss technical d...
متن کاملRefactoring of UML models using AGG
Model refactoring is an emerging research topic that is heavily inspired by refactoring of object-oriented programs. Current-day UML modeling environments provide poor support for evolving UML models and applying refactoring techniques at model level. As UML models are intrinsically graph-based in nature we propose to use graph transformations to specify and apply model refactoring. More in par...
متن کاملAGG: A Tool Environment for Algebraic Graph Transformation
AGG is a general tool environment for algebraic graph transformation which follows the interpretative approach. Its special power comes from a very exible attribution concept. AGG graphs are allowed to be attributed by any kind of Java objects. Graph transformations can be equipped with arbitrary computations on these Java objects described by a Java expression. The AGG environment consists of ...

Voltage-dependent Na + channels are thought to sense membrane potential with fixed charges located within the membrane's electrical field. Measurement of open probability (Po) as a function of membrane potential gives a quantitative indication of the number of such charges that move through the field in opening the channel. We have used single-channel recording to measure skeletal muscle Na § c...
