The first of the three artifacts that have been accepted at SEAMS'15 is online and enriching the Exemplars section of this website:
Distributed Dependable Ensembles of Components (DEECo)
by Michal Kit, Ilias Gerostathopoulos, Tomas Bures, Petr Hnetynka, and Frantisek Plasil.
"To develop self-adaptive cyber-physical systems (CPS) we advocate the use of component-based abstractions and related tools. DEECo is a component system (model and runtime platform) that provides the architecture abstractions of autonomous components and dynamic component groups (called ensembles) on top of which different adaptation techniques can be deployed. This makes DEECo a vehicle for seamless experiments with self-adaptive systems where the physical distribution and mobility of nodes, and the limited data availability play an important role."
