Following the approach introduced in [SIAM J. Sci. Comput., 35 (2013), pp. B487– B510], we consider the formulation of the problem of fluid flow in a system of fractures as a PDE constrained optimization problem, with discretization performed using suitable extended finite elements; the method allows independent meshes on each fracture, thus completely circumventing meshing problems usually rel...

Zusammenfassung In diesem Paper stellen wir ein Echtzeit-Szenario zur Überwachung und Steuerung von entfernt laufenden Großsimulationen vor, das auf einer Extraktion von Geometrien aus den Simulationsdaten, deren Übertragung über Hochgeschwindigkeitsnetze zu einem Client und der daraufhin erfolgenden Simulationssteuerung beruht. Wir stellen die Probleme eines solchen Szenarios dar und präsentie...

Abstract In this paper we present a general framework for the transmission of interactive media with real-time characteristics, i.e. media involving user interaction. By identifying and supporting the common aspe...

This paper examines the identification of the parameters of the Doyle-Fuller-Newman electrochemistry-based Lithium-ion battery model from voltage and current cycling data. The battery used in this study has a lithium iron phosphate cathode chemistry intended for high-power applications such as plug-in hybrid electric vehicles. The variables optimized for model identification include parameteriz...

Abstract Fireballs are infrequently recorded by seismic sensors on the ground. If recorded, they usually reported as one-off events. This study is first bulk analysis of largest single fireball data set, observed Desert Fireball Network (DFN) in Australia period 2014–2019. The DFN typically observes fireballs from cm-m scale impactors. We identified 25 time series Australian National Seismograp...

This paper proposes a method for quantitative integration of seismic (elastic) anisotropy attributes with reservoir performance data as an aid in characterization of systems of natural fractures in hydrocarbon reservoirs. This method is demonstrated through application to history matching of reservoir performance using synthetic test cases. Discrete Feature Network (DFN) modeling (Dershowitz et...
