Live Sequence Charts (LSCs) are a broad extension to Message Sequence Charts (MSCs) to capture complex interobject communication rigorously. A tool support for LSCs, named PlayEng...
We present a graphical semantics for the pi-calculus, that is easier to visualize and better suited to expressing causality and temporal properties than conventional relational se...
We discuss four issues concerning the semantics of Message Flow Graphs (MFGs). MFGs are extensively used as pictures of message-passing behavior. One type of MFG, Message Sequence...

In industrial requirements documents natural language is the main presentation means. In such documents, system behavior is specified in the form of scenarios, written as a seque...
