VQLS Read the Fine Print: Practical Challenges for Solving the Poisson Equation by Means of a Variational Quantum Linear Solver

The need of computational power for engineering applications has been ever increasing and with classical computers approaching their physical limits, new ways of improvement have to be investigated. One of the promising solutions is quantum computing. Most engineering problems require solving a system of linear equations of higher dimensions and...

Identification of a dynamic center line model and its implementation in FLORIDyn: A comparison between MOESP and DMDc system identification

Wind energy plays an essential role in the transition to a sustainable future and wind turbines allow us to utilize it. Wind turbines are often installed in close proximity to make the best use of the given space and to save costs. This also has the disadvantage that the turbines influence each other due to wakes. This is where wind farm control...

Encoding undirected and semi-directed binary phylogenetic networks by quarnets

Phylogenetic networks generalize evolutionary trees and are commonly used to represent evolutionary relationships between species that undergo reticulate evolutionary processes such as hybridization, recombination and lateral gene transfer. In this thesis all quarnets, networks on four species, of a network are assumed to be known. We prove that...

Automated Execution Process Formulation using Sequencing and Decomposition Algorithms for Collaborative MDAO

With Multidisciplinary Design Analysis and Optimization (MDAO) a fully automated aircraft design analysis is set up and optimization algorithms are used to obtain better designs by balancing the synergy between components. In the EU project AGILE, a new methodology and framework were developed to make the MDAO approach more accessible to...

SDP-based Max-2-Sat Decomposition

The Max-Sat problem has been intensively studied during the past few decades. Semi-definite programming based approximation algorithms provide good approximation ratios and polynomial runtime solutions to this problem. Unfortunately the high degree of their polynomial runtime prevents their application to problems with a large number of...
