Flexibility in Process-Aware Information Systems [chapter]

Manfred Reichert, Stefanie Rinderle-Ma, Peter Dadam
2009 Lecture Notes in Computer Science  
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.  ...

Towards preserving correctness in self-managed software systems

Lieven Desmet, Nico Janssens, Sam Michiels, Frank Piessens, Wouter Joosen, Pierre Verbaeten
2004 Proceedings of the 1st ACM SIGSOFT workshop on Self-managed systems - WOSS '04  
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?  ...

Data flow abstractions and adaptations through updatable process views

Jens Kolb, Manfred Reichert
2013 Proceedings of the 28th Annual ACM Symposium on Applied Computing - SAC '13  
The increasing adoption of process-aware information systems (PAISs) has resulted in large process model collections.  ...  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.  ...

We then identify relevant properties (Section 3) guaranteeing correctness, and adapt the database concept of linearizability (Section 4) to allow concurrency in SDN while preserving correctness.  ...  We adapt the properties to SDN to guarantee a correct distributed data-plane. We do not consider network failures in this paper and leave durability as future work.  ...

Correctness criteria for dynamic changes in workflow systems––a survey

Stefanie Rinderle, Manfred Reichert, Peter Dadam
2004 Data & Knowledge Engineering  
Along this classification we present important criteria for the correct adaptation of running workflows and analyze how actual approaches satisfy them.  ...  The capability to dynamically adapt in-progress workflows (WF) is an essential requirement for any workflow management system (WfMS).  ...  Data flow is modeled by connecting global process variables (D) with activities (N ) either by read or write data edges (DataE).  ...

Towards Compliance of Cross-Organizational Processes and Their Changes [chapter]

David Knuplesch, Manfred Reichert, Jürgen Mangler, Stefanie Rinderle-Ma, Walid Fdhila
2013 Lecture Notes in Business Information Processing  
In this paper, we discuss requirements and challenges to be tackled in order to ensure that changes of cross-organizational business processes preserve compliance with imposed regulations, standards and  ...  Businesses require the ability to rapidly implement new processes and to quickly adapt existing ones to environmental changes including the optimization of their interactions with partners and customers  ...  In the context of (dynamic) process changes, state consistency and data consistency respectively, must be preserved; i.e., a running process instance must not face deadlocks, lifelocks, and data-flow errors  ...

A cross-media adaptation strategy for multimedia presentations

Susanne Boll, Wolfgang Klas, Jochen Wandel
1999 Proceedings of the seventh ACM international conference on Multimedia (Part 1) - MULTIMEDIA '99  
Additionally, during presentation, substitution models enforce a semantically correct information flow in case of dynamic adaptation to varying presentation resources.  ...  The cross-media adaptation strategy allows for flexible reuse of multimedia content in many different environments and, at the same time, maintains a semantically correct information flow of the presentation  ...  In this paper, we propose formal models that ensure that the presentation alternatives preserve the presentation semantics and a correct flow of information.  ...

Deinterlacing with Motion-Compensated Anisotropic Diffusion [chapter]

Matthias Ghodstinat, Andrés Bruhn, Joachim Weickert
2009 Lecture Notes in Computer Science  
Then we apply the variational optic flow technique of Brox et al. (2004) in order to obtain a precise interframe registration.  ...  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.  ...
