In response to this drawback, adaptive PAIS have emerged, which allow to dynamically adapt or evolve the structure of process models under execution. ...
Once a process is implemented, its logic cannot be adapted or refined anymore. This often leads to rigid behavior or gaps between real-world processes and implemented ones. ...
Data Flow Correctness So far, we have not considered data flow correctness in connection with process changes. ...

We discuss the importance of consistent software compositions in the context of self-managed systems, and the need for a correctness-preserving adaptation process. ...
In this paper, we focus on the complexity of preserving correctness in modularized selfmanaged systems. ...
• Can our presented correctness be relaxed in some cases, such as allowing a temporary non-consistent composition or a correctness-unpreserving update process? ...

In the context, of a view change we ensure up-to-dateness and consistency of all process views related to the same process model. ...
Next, property data flow correctness preserving describes, which operations preserve data flow correctness and which might violate it. ...

Finally we use a spatiotemporal generalisation of EED for motion-compensated inpainting of the missing data in the original sequence. ...
In this context, one should note that without the preservation of motion boundaries, blurry flow information would lead to a filling-in of wrong temporal data at the corresponding image locations. ...
