    Application and Testing of Business Processes in the Energy Domain
    (Datenbanksysteme für Business, Technologie und Web (BTW 2017) - Workshopband, 2017) Böhmer, Kristof; Stertz, Florian; Hildebrandt, Tobias; Rinderle-Ma, Stefanie; Eibl, Günther; Ferner, Cornelia; Burkhart, Sebastian; Engel, Dominik
    The energy domain currently struggles with radical legal and technological changes, such as, smart meters. This results in new use cases which can be implemented based on business process technology. Understanding and automating business processes requires to model and test them. However, existing process testing approaches frequently struggle with the testing of process resources, such as ERP systems, and negative testing. Hence, this work presents a toolchain which tackles that limitations. The approach uses an open source process engine to generate event logs and applies process mining techniques in a novel way.

    Digital weed reduction
    (43. GIL-Jahrestagung, Resiliente Agri-Food-Systeme, 2023) Burkhart, Sebastian; Noack, Patrick
    In an effort to reduce the usage of herbicides in herb cultivation, we discuss strategies to detect and eliminate toxic weeds, exemplified by Senecio vulgaris. This paper presents a method to classify plants based on their spectral characteristics utilizing hyperspectral imagery in the range between 400 nm and 1100 nm. We are able to remove background material by masking it automatically using the well-established NDVI and Otsu’s thresholding prior to classification. Based on a neural network, we correctly classify 93% of the leaf area from Senecio vulgaris even with a relatively low spectral resolution of 50 nm. Apart from data collection, all steps were implemented in open source software and the Python language using open source libraries.
