Dear colleagues,

You are cordially invited to attend the following presentation on
important extensions to the ToolBus language.

Time   : 10:00
Date   : June 7th, 2007
Room   : M280, CWI
Speaker: Dennis Hendriks (Master student TU Eindhoven)

Titel   : The ToolBus - Hierarchy, abstraction, namespaces and dependability
Abstract:
The ToolBus coordination architecture has some features (like its basis
in process algebra), which make it unique. However, the ToolBus can
still be improved in several ways. In my master's project I (mainly)
concentrate on adding more structure to the (currently unstructured)
group of ToolBus processes. I propose a hierarchical structure of
ToolBus processes and a communication restriction that enforces
abstraction. The benefit of my approach includes (among others) clearly
defined interfaces for subsystems and easier reuse of those subsystems.
I also introduce namespaces (for messages, notes and processes) in order
to solve the problem of name clashes, while at the same time adding more
abstraction. Finally, I make a first step towards dependable ToolBus
systems. As part of my master's project, I will not only design these
improvements, but I will also implement them in the Java version of the
ToolBus (ToolBusNG).


Best regards,

Jurgen Vinju
