  abstract = {Many Embedded Systems are supposed to run continuously, which includes
	recovering from errors by adapting their configuration or their architecture
	to changing conditions in their environment. The design of such systems
	has to relate some high-level extra-functional properties to some
	low level ones such as memory or CPU consumption by defining some
	complex feed-back loops for the dynamic adaptation of the system.
	However, although feed-back loops (also known as "adaptation policies")
	are a well-known idea, the design phase does not deal with those
	feed-back loops and thus the needed sensors and actuators are hard-coded
	during the development phase. This leads to expensive roll-back operations
	in the design process. To avoid that, we suggest a model-driven process
	based on new executable meta-modelling techniques. At modelling time,
	designers have to complement the architectural description with some
	sensors and actuators related to the involved extra-functional properties.
	It allows designers to specify in a consistent way the related adaptation
	policies. Then, since the models are executable, some simulations
	of the adaptation policies can be performed at design time to evaluate
	their performances with respect to some relevant test scenarios.},
