    A Framework for Supporting the Workflow for Archaeo-related Sciences: Managing, Synchronizing and Analyzing Data
    (Datenbanksysteme für Business, Technologie und Web (BTW 2017) - Workshopband, 2017) Kaltenthaler, Daniel; Lohrer, Johannes-Y.; Kröger, Peer; Obermaier, Henriette
    In this paper we analyze the challenges of the workflow in archaeo-related disciplines. We extract the main parts of the workflow and consider them in our solution for an eScience service in this domain. First, we describe the dynamic framework xBook to be used for different archaeo-related databases. Afterwards, we show the Synchronization supporting the collaboration with colleagues and sharing data. Finally, we describe the Analysis Tool, that allows analyses to be executed directly inside the framework. Concluding, we show a sample analysis in OssoBook, a zooarchaeological database.

    Model-based Real-time Synchronization
    (Softwaretechnik-Trends Band 34, Heft 2, 2014) Krusche, Stephan; Bruegge, Bernd
    In this paper we describe an approach for model-based realtime synchronization. We present an extension of the EMFStore platform which allows multiple collaborators to connect to each other directly via peer-to-peer and to synchronize changes on model instances with each other in real-time. With this approach we allow users to collaboratively work literally on the same model instance. We argue that this approach avoids serious conflicts and reduces the problem of outdated model instances.

    Path Expressions Revisited
    (Tagungsband des FG-BS Herbsttreffens 2024, 2024) Hövelmann, Thomas Alexander; Krause, Alexander; Ulbrich, Peter
    Path expressions provide a precise and concise method for defining synchronization rules for accessing shared data. In conjunction with predicates, even finer control of the sequences can be achieved. Furthermore, path expressions, with their ability to abstract from a specific synchronization technique, demonstrate a high level of adaptability. Despite being developed nearly five decades ago, they remain underrepresented in current software engineering and have yet to achieve widespread applicability. This paper reevaluates existing approaches and presents an automaton-based version of path expressions written in C++. We extend the concept of predicates to allow access to external system states and evaluate the feasibility and performance of our approach.

    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.
