    Online monitoring for safety-critical multicore systems
    (it - Information Technology: Vol. 59, No. 5, 2017) Tobuschat, Sebastian; Kostrzewa, Adam; Bapp, Falco K.; Dropmann, Christoph
    Using multicore processors in safety-critical systems is a challenge as well as an opportunity. The real parallelism, which may affect synchronization and determinism, leads to a safety-challenge, because new possible interferences might arise. Additionally, redundant software execution is possible within multicore systems. In complex multicore architectures one of the most important challenges is to know the system behavior and the recognition of any variations from the normal system behavior has to be guaranteed. For those cases it is necessary to monitor several states of the system, configurations, timing, etc. To monitor such a complex system a lot of information from the inside of the system needs to be evaluated without affecting the rest of the MPSoC.

    Robust preprocessing of time series with trends
    (Informatik bewegt: Informatik 2002 - 32. Jahrestagung der Gesellschaft für Informatik e.v. (GI), 2002) Fried, Roland; Gather, Ursula
    Physiological time series measured in intensive care exhibit trends, level changes and periods of relative constancy. This signal is overlaid with a high level of noise and many measurement artifacts, and there are dependencies between the different items measured. We develop a method which allows a reliable denoising of the data and which can separate artifacts from relevant changes in the patients condition. For clinical online application the method has to be automatized and work in real time.
