Donker, Quinten (author)This thesis is about Van Kampen's theorem and fundamental groupoids. Van Kampen's Theorem is a classical result in algebraic topology, which proposes a way of calculating the fundamental group of a topological spaces using the fundamental groups of certain subspaces. In this thesis we will construct the fundamental group, which intuitively...bachelor thesis 2023

van Heiningen, Jeroen (author)The goal of this paper is to formalize the Fundamental Group of the Circle within Coq and the Unimath library, as described in the paper by Mr Licata and Mr Shulman, and show it is isomorphic to Z. Fundamental groups are a powerful algebraic invariant for studying Homotopy theory, and provide deep, yet concise insights into the fundamental...bachelor thesis 2023

van der Drift, R. (author), de Haan, J.G. (author), Boelhouwer, P.J. (author)Over the last decade, house prices have increased substantially in nearly all OECD countries. These house price increases frequently coincided with changes in mortgage credit conditions; i.e., decreases in the interest rate and increases in income. This is in line with existing literature, which finds an equilibrium relationship between...journal article 2023

Jiao, Y. (author), Calvert, S.C. (author), van Cranenburgh, S. (author), van Lint, J.W.C. (author)This study presents a new method to infer the average two-dimensional (2D) spacing between interacting vehicles in urban traffic from trajectory data. In this context, 2D spacing reflects the amount of road space consumed by pairs of interacting vehicles, and is related to 2D density at the macroscopic level. Due to complex interaction and...journal article 2023

Xu, Y. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author), Yuan, S. (author), Chen, Chao (author)Domino accidents are typical low-frequency and high-consequence events in chemical process industries. Applying quantitative risk assessment (QRA) in domino accident assessment is challenging due to the uncertainties in the escalation process. Meanwhile, the outcomes of QRA are subject to a certain degree of unreliability due to the...journal article 2023

Gomez Beldarrain, Garoa (author)Vehicle automation will increasingly release car drivers from driving tasks, allowing them to engage in previously inconceivable activities. Experiential components are therefore expected to become central in human automotive mobility. In this context, the design of future in-vehicle experiences is a research gap to still discover, that concerns...master thesis 2022

Vermolen, F.J. (author), Bakker, D.R. (author), Vuik, Cornelis (author)The discretisation of the Laplacian results into the well-known Laplace matrix. In the case of a one dimensional problem, an explicit formula for its inverse is derived on the basis of fundamental solutions (Green’s functions) for general boundary conditions. For a linear reaction–diffusion equation, approximations of the inverse are given.journal article 2022

(author), Yao, Z. (author), Zeman, M. (author), Santbergen, R. (author), Mazzarella, L. (author), Isabella, O. (author)Thin films of transition metal oxides such as molybdenum oxide (MoO<sub>x</sub>) are attractive for application in silicon heterojunction solar cells for their potential to yield large short-circuit current density. However, full control of electrical properties of thin MoO<sub>x</sub> layers must be mastered to obtain an efficient hole...journal article 2022

Li, D. (author), De Schutter, B.H.K. (author)Data-driven control without using mathematical models is a promising research direction for urban traffic control due to the massive amounts of traffic data generated every day. This article proposes a novel distributed model-free adaptive predictive control (D-MFAPC) approach for multiregion urban traffic networks. More specifically, the...journal article 2022

Orçun, S.E. (author)The ongoing Covid-19 pandemic has led to an unprecedented public health crisis worldwide starting from the early days of 2020. Alongside the medical concerns, a set of measures called non-pharmacological interventions (NPIs) affected daily lives of people drastically, in turn having a negative impact on subjective well-being (Berg, 2021; Wang et...master thesis 2021

Dooren, Kari (author)This project is about inclusion in the museum sector. Concerns around inclusion and equality are rapidly increasing. And, due to these societal dynamics, museums are in times of fundamental change towards inclusivity.<br/><br/>At the start of the project, a theoretic framework depicting the different layers and elements of inclusion was...master thesis 2021

Wierbos, M.J. (author)This dissertation studies the dynamics of bicycle traffic flow. The research focuses on busy situations such as bicycle queues at intersections and congestion upstream of a bottleneck. The cycling movements are analyzed on the aggregated scale in terms of density, speed and flow. Furthermore, cyclists are included in a traffic flow model by...doctoral thesis 2021

Palla, Pallavi (author)The gas production in the Groningen gas field of the Netherlands has caused a significant amount of shallowhuman induced earthquakes. Among various building typologies, Groningen is home to many Dutch historical churches constructed by unreinforced masonry which has shown to be highly vulnerable to these earthquakes. From the perspective of...master thesis 2021

Aarts, Michiel (author)The traffic density of small aerial vehicles operating within urban environments is expected to increase significantly in the near future. This urban environment is highly constrained due to being limited to the low-altitude airspace directly above the existing road network. To increase understanding of the factors influencing the capacity of...master thesis 2021

Keyvan-Ekbatani, Mehdi (author), Carlson, Rodrigo Castelan (author), Knoop, V.L. (author), Papageorgiou, Markos (author)Perimeter traffic flow control based on the macroscopic or network fundamental diagram provides the opportunity of operating an urban traffic network at its capacity. Because perimeter control operates on the basis of restricting inflow via reduced green times at selected entry (gated) links, vehicles on those links may be subject to queuing and...journal article 2021

(author), Menendez, Monica (author), Axhausen, Kay W. (author)Interactions among different modes or vehicle classes in urban road networks affect the network performance in different and complex ways. Thus, an answer to the question of “how many cars are too many for a city?” is not trivial. However, multi-modal macroscopic fundamental diagrams (MFD) offer a novel opportunity to answer this question. So...journal article 2021

van Dijk, Marieke (author)The term ‘polarization’ has become well-known in the public debate. In January 2019, the SCP (Netherlands Institute for Social Research) reported that 77% of the Dutch citizens think disagreements on social issues increase. As we mostly hear and see the more extreme and opposing sides in the media, it seems like society is divided about many...master thesis 2020
