Quantum Computing for Query Containment of Conjunctive Queries
Luisa Gerlach, Tobias Köppl, René Zander +2
We address the problem of checking query containment, a foundational problem in database research. Although extensively studied in theory research, optimization opportunities arisi…
Data-driven Neural Networks for Windkessel Parameter Calibration
Benedikt Hoock, Tobias Köppl
In this work, we propose a novel method for calibrating Windkessel (WK) parameters in a dimensionally reduced 1D-0D coupled blood flow model. To this end, we design a data-driven n…
A parameter study for LLL and BKZ with application to shortest vector problems
Tobias Köppl, René Zander, Louis Henkel +1
In this work, we study the solution of shortest vector problems (SVPs) arising in terms of learning with error problems (LWEs). LWEs are linear systems of equations over a modular…
A 1D-0D-3D coupled model for simulating blood flow and transport processes in breast tissue
Marvin Fritz, Tobias Köppl, J. Tinsley Oden +3
In this work, we present mixed dimensional models for simulating blood flow and transport processes in breast tissue and the vascular tree supplying it. These processes are conside…
Analysis of a new multispecies tumor growth model coupling 3D phase-fields with a 1D vascular network
Marvin Fritz, Prashant K. Jha, Tobias Köppl +2
In this work, we present and analyze a mathematical model for tumor growth incorporating ECM erosion, interstitial flow, and the effect of vascular flow and nutrient transport. The…
A 3D-1D coupled blood flow and oxygen transport model to generate microvascular networks
Tobias Köppl, Ettore Vidotto, Barbara Wohlmuth
In this work, we introduce an algorithmic approach to generate microvascular networks starting from larger vessels that can be reconstructed without noticeable segmentation errors.…
Hybrid models for simulating blood flow in microvascular networks
Ettore Vidotto, Timo Koch, Tobias Köppl +2
In this paper, we are concerned with the simulation of blood flow in microvascular networks and the surrounding tissue. To reduce the computational complexity of this issue, the ne…
