    The Need for an Open Corpus of Software Architecture Descriptions
    (Softwaretechnik-Trends: Vol. 37, No. 2, 2017) Knodel, Jens; Buckley, Jim; Herold, Sebastian
    Software architectures are the conceptual tool to share information about key aspects of a software system and to enable reasoning about the principal, most fundamental, and often most difficult-to-change design decisions of the system. Studies of failed software systems give evidence that architecture drift, erosion or degradation is a prevalent problem in industrial practice. But a recent systematic literature review [9] indicates that research currently investigates compliance checking or inconsistency detection only. To advance research we need an open and grounded corpus of software architecture description – serving as a basis for more sophisticated studies beyond detection only. Such a corpus could enable (1) to evaluate new approaches, (2) to provide means for fixing degradation (when it occurs or a-posteriori), (3) to compare and benchmark approaches and, ultimately, (4) enable longitudinal studies in the field.

    Towards COTS component synchronization for low SWaP-C flight control systems
    (SE 2024 - Companion, 2024) Sax, Franz; Holzapfel, Florian
    The rise of innovative and novel fly-by-wire air vehicles like e-VTOLs for Advanced Air Mobility demands flight control systems whose components are low size, weight, power and cost (SWaP-C), but nevertheless offer high performance. One approach towards this mismatch is to use COTS components from e.g. the automotive sector and use their extensive features to enhance performance in a given system architecture. This paper describes one method of minimizing the latency in the communication between two COTS components by using an easily realizable algorithm with minimal memory, code and computation requirements for relative synchronization of the execution cycles of the components. A description of the resulting control problem, as well as simulation results from a dedicated MATLAB simulation environment are given. Those are then compared with an implementation on a representative set of devices from the EPUCOR flight control system.
