Cyber-Physical Systems are distributed, heterogeneous systems that communicate and exchange data over networks. This creates semantic dependencies between the individual components. In the event of an error, it is difficult to identify the source of an occurring error that is spread due to those underlying dependencies. Tools such as the Information Flow Monitor solve this problem, but require compliance with a protocol. Nodes that do not adhere to this protocol prevent errors from being tracked. In this paper, we present a way to bridge these black-box nodes with a dependency model and to still be able to use them in monitoring tools.

In rapid continuous software development, time- and cost-effective prototyping techniques are beneficial through enabling software designers to quickly explore and evaluate different design concepts. Regarding low-fidelity prototyping for augmented reality (AR) applications, software designers are so far restricted to non-digital prototypes, which enable the visualization of first design concepts, but can be laborious in capturing interactivity. The lack of empirical values and standards for designing user interactions in AR-software leads to a particular need for applying end-user feedback to software refinement. In this paper we present the concept of a tool for rapid digital prototyping for augmented reality applications, enabling software designers to rapidly design augmented reality prototypes, without requiring programming skills. The prototyping tool focuses on modeling multimodal interactions, especially regarding the interaction with physical objects, as well as performing user-based studies to integrate valuable end-user feedback into the refinement of software aspects.

A number of small Open Source projects let independent providers measure different aspects of their quality that would otherwise be hard to see. This paper describes this observation as the pattern Quality Attestation. Quality Attestation belongs to a family of Open Source patterns written by various authors.
