Artifact for "Building real-time digital twin instances with Function+Data Flow: user evaluation and extension for iterative pipelines"

This is the supplementary material for the research paper **Building real-time digital twin instances with Function+Data Flow: user evaluation and extension for iterative pipelines** In this paper, we evaluate the Function+Data Flow framework and its implementation in DesCartes Builder with a user study, and we propose the H-FDF extension supporting iterative pipelines. We employed DesCartes Builder v.0.2.2 in the user study. The tool installer is available at https://zenodo.org/records/18757324 and the corresponding source is at https://github.com/CPS-research-group/descartes-builder. This artifact include:- Use case pipelines - 'minimal.dcb': minimal pipeline (Fig. 3) - 'pipe-deformation-train.dcb': training of pipe deformation use case (Fig. 8) - 'pipe-deformation-test.dcb': testing of pipe deformation use case (Fig. 9) - 'user-study-material': Material used during the workshop evaluating the tool.- 'user-study-analysis': user study raw study and their scripts for their analysis, enabling to recreate the figures in Section 5. - 'knime-vs-fdf': pipelines discussed in the comparison of FDF/H-FDF with KNIME (Fig. 5 and Fig. 18)
