In B, the expression of dynamic constraints is notoriously missing. In this paper, we make various proposals for introducing them. They all express, in di erent complementary ways,...
Abstract. This paper shows how systems can be built from their component parts with specified sharing. Its principle contribution is a modular language for configuring systems. A c...

Descriptions of reactive systems focus heavily on behavioral aspects, often in terms of scenarios. To cope with the increasing complexity of services provided by these systems, beh...
Abstract. A collection of user interface design patterns for workflow information systems is presented. Each Workflow User Interface Pattern (WUIP) is characterized by properties e...
