In dieser Arbeit wird ein mathematisches Modell beschrieben, welches den O2- und CO2-Stoff-wechsel am isolierten Herzen in den drei Kompartimenten Plasma, interstitiale Flüssigkeit und Parenchymalzellen beschreibt unter Berücksichtigung des Carbonat- und Phosphatpuffergleich-gewichtes. Mit Hilfe dieses Modells wird nach möglichen Sensoren für eine experimentell festge-stellte Flussänderung unter hyperkapnischen Bedingungen gesucht. Dazu werden die Zeitska-len der einzelnen Prozesse analysiert und es wird versucht einen Regelkreis zur Flusssteuerung in das Modell einzubringen. Zudem wird das Modell in MatLab implementiert, um dort mittels Bayes’scher Datenanalyse die Parameter des Modells an die experimentell gemessenen Werte anzupassen
Biconnected reliability
(2015)
Computer communication networks play a mayor role to manage data transfer and information processing. However, the components of the network may fail - by targeted attacks or by wearout. While targeted attacks are non-random, it seems appropriate to consider wearout effects as random. Further we can assume that the components fail independently. The task of network reliability is to analyze networks in respect to the functionality of the network with consideration of wearout of its components. In most cases a network is considered as functional if a selected set of terminals can communicate. ...
Beam shaping and splitting with diffractive optics for high performance laser scanning systems
(2021)
Diffractive optical elements (DOEs) enable novel high performance and process-tailored scanning strategies for galvanometer-based scan heads. Here we present several such concepts integrating DOEs with laser scanners and the respective application use cases. Beam shaping DOEs providing a homogeneous fluence over a custom defined profile, such as a rectangular Top-Hat, enable increased process quality in Laser-Induced Forward Transfer (LIFT) compared to the Gaussian beam of the laser source. We show that aberrations which occur over the necessary large wafer-sized image field can be eliminated through the use of a synchronous XY-stage motion. Another application that benefits from the use of DOEs is laser drilling. Drilling in display and electronics manufacturing demands high throughput that can only be achieved through the use of beam splitting DOEs for parallel processing. To this end, the joint MULTISCAN project is developing a variable multi-beam tool capable of scanning and switching each individual beamlet for increased control.
