Klein, R.B. (author), Sanderse, B. (author)A novel hyper-reduction method is proposed that conserves kinetic energy and momentum for reduced order models of the incompressible Navier-Stokes equations. The main advantage of conservation of kinetic energy is that it endows the hyper-reduced order model (hROM) with a nonlinear stability property. The new method poses the discrete...journal article 2024

Martinelli, Cristiano (author), Coraddu, A. (author), Cammarano, Andrea (author)Lightweight structures, once ubiquitous in specific sectors such as aeronautics and space sectors, in recent years, have increasingly attracted the attention of industries that, historically, have not been particularly concerned with structural weight. Ample examples are provided by the civil and automotive industry, in which the paradigm...journal article 2024

Brown, Jason I. (author), Kolokolnikov, Theodore (author), Kooij, Robert (author)We introduce two new methods for approximating the all-terminal reliability of undirected graphs. First, we introduce an edge removal process: remove edges at random, one at a time, until the graph becomes disconnected. We show that the expected number of edges thus removed is equal to (Formula presented.), where (Formula presented.) is the...journal article 2024

Hagen, W.R. (author)The electron–electron, or zero-field interaction (ZFI) in the electron paramagnetic resonance (EPR) of high-spin transition ions in metalloproteins and coordination complexes, is commonly described by a simple spin Hamiltonian that is second-order in the spin S: ℋ=[2−(+1)/3+(2−2). Symmetry considerations, however, allow for fourth-order terms...journal article 2024

Hsu, Hsing-Li (author)Reset controllers are acknowledged for their potential to enhance performance, like speed and precision in precision motion industries. Existing literature primarily utilizes the classical zero-crossing law in these controllers. This study introduces a novel reset component, termed “fixed-phase reset control”, which employs an innovative reset...master thesis 2023

Sofia-Gabrion, Grégoire (author)A series of numerical simulations was executed using the high-performance cluster at TU Delft's Aerospace Faculty. The primary objective was to gain deeper insights into the intricate dynamics of a sonic transverse jet in a supersonic crossflow with an oblique induced shock wave, especially concerning mixing. These simulations delved into the...master thesis 2023

Karbasizadeh, Nima (author)This dissertation addresses the demand for faster, more precise, and robust controllers in the precision motion industry. Traditional linear controllers have limitations due to the waterbed effect and Bode’s phase-gain relationship. To overcome these limitations, complex-order controllers are explored in this study. The dissertation focuses on...doctoral thesis 2023

Jung-Muller, Mathieu (author)Temporal networks, like physical contact networks, are networks whose topology changes over time. However, this representation does not account for group interactions, when people gather in groups of more than two people, that can be represented as higher-order events of a temporal network. The prediction of these higher-order events is usually...master thesis 2023

Liu, Chengen (author)The edge flow reconstruction task improves the integrity and accuracy of edge flow data by recovering corrupted or incomplete signals. This can be solved by a regularized optimization problem, and the corresponding regularizers are chosen based on prior knowledge. However, obtaining prior information is challenging in some fields. Thus, we...master thesis 2023
