Cheizoo, Bas (author)The speed and precision required in the precision motion industry is an ever-growing challenge. Linear control offers intuitive frequency-domain controller design methods that are based on a frequency response function (FRF) of the plant, which is obtained solely from measurement data. Unsurprisingly, linear controllers account for over 90% of...master thesis 2024

Roozendaal, Tim (author)The focus of this thesis is the hydrodynamic limit of the Brownian Energy Process (BEP) and the<br/>Asymmetric Brownian Energy Process (ABEP) in infinite volume. The thesis starts by introducing some general theory about Markov processes, after which the topic of Markov duality is introduced. A number of relevant interacting particle systems ...master thesis 2024

Groen, S. (author)This thesis investigates how the design of prisons affects the rehabilitation of prisoners. It focuses on the Dutch prison system while drawing comparisons with Norway’s progressive approach. The study analyzes how the environment within prisons affects the well-being of inmates and their potential for reintegration into society. It examines the...student report 2024

Castiel Reis de Souza, A. (author), Elisiário de Carvalho, Darlan Karlo (author), de Moura Cavalcante, Túlio (author), Licapa Contreras, Fernando Raul (author), Edwards, Michael G. (author), Lyra, Paulo Roberto Maciel (author)A novel Flux Limited Splitting (FLS) non-linear Finite Volume (FV) method for families of linear Control Volume Distributed Multi Point Flux Approximation (CVD-MPFA) schemes is presented. The new formulation imposes a local discrete maximum principal (LDMP) which ensures that the discrete solution is free of spurious oscillations. The FLS scheme...journal article 2024

Jain, A. (author), Marykovskiy, Yuriy (author), Metrikine, A. (author), van Dalen, K.N. (author)Railway transition zones (RTZs) are regions where abrupt track stiffness changes occur that may lead to dynamic amplifications and subsequent track deterioration. The design challenges for these zones arise due to variations in material properties in both the depth (trackbed layers composed of different materials) and longitudinal directions of...journal article 2024

Heidary, Amir (author), Ghaffarian Niasar, M. (author), Popov, M. (author)The rapid increase of integrated distributed generators results in higher fault currents in the future modern grids. A remedy for the concern is employing series reactors as fault current limiters. This paper elaborates on a ferromagnetic core series reactor, which, when saturated, adversely affects the operation of the series reactor during...journal article 2024

Bravin, M. (author), Nečasová, Šárka (author)In this paper, we study the dynamics of a small rigid body in a viscous incompressible fluid in dimension two and three. More precisely we investigate the trajectory of the rigid body in the limit when its mass and its size tend to zero. We show that the velocity of the center of mass of the rigid body coincides with the background fluid...journal article 2024

Bai, Chengchao (author), Yan, Peng (author), Piao, Haiyin (author), Pan, W. (author), Guo, Jifeng (author)This article explores deep reinforcement learning (DRL) for the flocking control of unmanned aerial vehicle (UAV) swarms. The flocking control policy is trained using a centralized-learning-decentralized-execution (CTDE) paradigm, where a centralized critic network augmented with additional information about the entire UAV swarm is utilized...journal article 2024

Zhang, Yuqi (author), Kaiser, Elias (author), Dutta, S. (author), Sharkey, Thomas D. (author), Marcelis, Leo F.M. (author), Li, Tao (author)Triose phosphate utilization (TPU) limitation is one of the three biochemical limitations of photosynthetic CO<sub>2</sub> assimilation rate in C<sub>3</sub> plants. Under TPU limitation, abrupt and large transitions in light intensity cause damped oscillations in photosynthesis. When plants are salt-stressed, photosynthesis is often down...journal article 2024

Horstman, Bart (author)This study introduces a new design for the drivetrain of a robotic ball. An application for the robotic ball is a rehabilitation device for young children. With these children, movement can be stimulated in a more intuitive way when a robotic ball is used compared to other training programs. Since the ball will be kicked and played with, an...master thesis 2023

van Tol, Berend (author)In this thesis, we study stochastic duality under hydrodynamic scaling in the context of interacting particles on a grid. The approach is inspired and motivated by the relation between duality and local equilibria. We identify duality relations in terms of the expectation of the density field for which the hydrodynamic limit is recovered. This...master thesis 2023

Schermerhorn, Rick (author)In this report we examine the dual space of $\ell^\infty$. If $p \in [1,\infty)$ and $q \in [1,\infty]$ satisfy $\frac{1}{p}+\frac{1}{q}=1$, then one can identify the spaces $\ell^q$ and $(\ell^p)'$ in a natural way via an isometric isomorphism. This identification does not extend to the case $p=\infty$ and $q=1$. We prove that the obvious...bachelor thesis 2023
