Koch, Matthijs (author)The current Dutch housing domain is characterised by injustices on multiple scales, such as a shortage of housing, disparities in well-being across regions, and unaffordable housing. This situation can partially be attributed to spatial planning practices focused on promoting growth-oriented economic thinking. These contemporary planning...master thesis 2024

Koch, Johannes (author)The Real-Valued Gene-pool Optimal Mixing Evolutionary Algorithm (RV-GOMEA) is a state-of-the-art algorithm for single-objective, real-valued optimization. As many practical applications are inherently constrained, evolutionary algorithms are equipped with constraint handling techniques to allow optimizing constrained problems. The approach...master thesis 2023

Koch, Joel (author)This thesis studies companies which developed open source software but adopted cloud protection licenses, a novel type of software licenses which protect their business from competitors but potentially affect their open source communities. It addresses the practical problem of executives of the companies who miss information about the effects of...master thesis 2023

Koch, Rouven (author), van Driel, D. (author), Bordin, A. (author), Lado, Jose L. (author), Greplová, E. (author)Determining Hamiltonian parameters from noisy experimental measurements is a key task for the control of experimental quantum systems. An interesting experimental platform where precise knowledge of device parameters is useful is the quantum-dot-based Kitaev chain. In these systems, the fine tuning of Hamiltonian parameters is crucial in...journal article 2023

(author), van Loosdrecht, Mark C.M. (author), Lücker, Sebastian (author)Dissimilatory nitrate reduction to ammonia (DNRA) is a common biochemical process in the nitrogen cycle in natural and man-made habitats, but its significance in wastewater treatment plants is not well understood. Several ammonifying Trichlorobacter strains (former Geobacter) were previously enriched from activated sludge in nitrate-limited...journal article 2023

de Koster, P.B.J. (author), Schulz, Olaf (author), Koch, Jonas (author), Pachnicke, Stephan (author), Wahls, S. (author)We experimentally investigate the problem of monitoring the Kerr-nonlinearity coefficient $\gamma$ from transmitted and received data for a single-mode fiber link of 1600 km length. We compare the accuracy and speed of three different approaches. First, a standard split-step Fourier method is used to predict the output at various $\gamma$...journal article 2023

Huang, Chloe (author), Koch, Matthijs (author), YU, Zhuo (author), van Hal, Sophie (author)Different government bodies, from the European Union down to the Port of Rotterdam Authority have implemented the policy goal to become circular by 2050 to minimize demand and dependence on finite resources. However, a circular economy - an economic model in which materials circulate in closed loops and waste is viewed as a resource - is vastly...student report 2022

Koch, Pim (author)Sea level rise caused by climate change directly affects and threatens low-lying countries. In August of 2021, the report of the IPCC was published, and the findings were disturbing. The sea could rise by a few meters in the coming centuries, causing floods in large parts of West-Europe. Groeskamp and Kjellson proposed a solution to adapt to the...master thesis 2022

de Koster, P.B.J. (author), Koch, Jonas (author), Schulz, Olaf (author), Pachnicke, Stephan (author), Wahls, S. (author)Recently, a nonlinear Fourier transform-based Kerr-nonlinearity identification algorithm was demonstrated for a 1000 km NZDSF link with accuracy of 75%. Here, we demonstrate an accuracy of 99% over 1600 km SSMF. Reasons for improved accuracy are discussed.conference paper 2022

Koch, Rik (author)This thesis considers the design of the sampling-driven nonlinear model predictive controller (SD-NMPC) for power electronic converters. Most MPC schemes that are used nowadays lack in the application for systems with high sampling frequencies because of their high computational time, especially when the system is nonlinear. This is, for example...master thesis 2021

Koch, Dave (author)This paper proposes a socio-technical agent-based model developed to increase the understanding of decision-making in an airline operational control center (AOCC). In this model human decision-makers, a Decision Support Tool, and technical systems are included. The selected case study encompasses the<br/>unexpected diversion of a flight from...master thesis 2021

(author), Vallina-Rodriguez, Narseo (author)The impact of Internet phenomena depends on how they impact users, but researchers lack visibility into how to translate Internet events into their impact. Distressingly, the research community seems to have lost hope of obtaining this information without relying on privileged viewpoints. We argue for optimism thanks to new network...conference paper 2021

Yet, literature primarily focuses on professional identity, based on institutionalized definitions of design to which students must conform. In contrast, we explore personal motivations for wanting to become a designer. An instrumental...conference paper 2020
