    A Polynomial-Time Algorithm for Detection of Uncovered Transitions in a Petri Net-Based Concurrent System by Marcin Wojnakowski, Maxim Maliński, Remigiusz Wiśniewski, Andrzej Obuchowicz, Zhiwu Li, Dawid Konarczak

    Published 2025-01-01
    “…Transition invariants play a crucial role in ensuring the correctness and reliability of such systems; however, existing methods often struggle with high computational demand, especially in the case of large and complex systems. The proposed approach addresses this challenge by performing a fast polynomial-time analysis to identify uncovered transitions, thereby streamlining the verification process. …”

    A FSTCN-Based Leak Detection Method for Large-Scale Pipeline Transportation Systems by Du Zhang, Chang-Su Kim, Chul-Hyun Hwang, Tae-Jun Lee, Hoe-Kyung Jung

    Published 2025-01-01
    “…Time series-based studies are widely used for leak detection in large-scale pipeline transportation systems, but single time-domain information, which ignores the spatial distribution of pressure sensors and does not consider periodic features, may not be sufficient for the detection accuracy of complex systems. To address it, a leak detection method based on frequency spatial-temporal convolution network (FSTCN) is proposed in this paper. …”
