FACULTY OF ENGINEERING ELECTRONICS AND COMPUTER SCIENCE DEPARTMENT Doctor of Philosophy MODELLING AND VERIFICATION OF EMBEDDED SYSTEMS BASED ON PETRI NET ORIENTED REPRESENTATIONS by Mauricio Varea Driven by the demand for more functionality, the complexity involved in the design of embedded systems continues to increase. This has lead to a progressive increase in the amount of control and data ...

In geological media, the large variety and complex configurations of fractured networks make it difficult to describe them precisely. A relevant approach is to model them as Discrete Fracture Networks (DFN)[10, 19], with statistical properties in agreement with in situ experiments [15, 13, 14]. A DFN is a 3D domain made of 2D fractures intersecting each other. Steady state flow in DFN is consid...

We present a topology-based method for mesh-partitioning in three-dimensional discrete fracture network (DFN) simulations that takes advantage of the intrinsic multi-level nature DFN. DFN models are used to simulate flow and transport through low-permeability fractured media subsurface by explicitly representing fractures as entities. The governing equations numerically integrated on computatio...

Seit 1994 wurden vom BMBF finanzierte DFN-Forschungsprojekte zu Verzeichnisdiensten an der Universität Tübingen durchgeführt. In den ersten dieser Projekte stand der Aufbau und Betrieb eines Emailverzeichnisses für die deutsche Forschung1 im Vordergrund. Zum Aufrechterhalt dieser Dienste kamen in den Folgeprojekten weitere Aufgaben hinzu, wie z.B. der Aufbau des Verzeichnisdienst-Kompetenzzentr...

Abstract PHANGS–JWST mid-infrared (MIR) imaging of nearby spiral galaxies has revealed ubiquitous filaments dust emission in intricate detail. We present a pilot study to systematically map the filament network (DFN) at multiple scales between 25 and 400 pc NGC 628. MIRI images 7.7, 10, 11.3, 21 ? m 628 are used generate maps emission, while PHANGS–HST B -band yields attenuation features. quant...

Sympathetic ophthalmia is a bilateral uveitis that develops after penetrating injury to one eye. This study aimed to identify the inflammatory cellular sub-phenotypes and expression of pertinent inflammatory cytokines/chemokines in sympathetic ophthalmia (SO). Dalen-Fuchs nodules (DFN), granulomas, and non-granulomatous foci of inflammation were micro-dissected from 15 cases. RNA was extracted,...
