Deng, X. (author)Tidal inlet systems, which consist of back–barrier basins connected to the open sea by one or multiple inlets, are found at many places along sandy coasts. They are valuable for ecology (breeding and feeding areas), economy (gas–mining and sand–mining) and recreation, and are important for coastal safety. But they are also sensitive to external...doctoral thesis 2023

Su, Jiahang (author), Li, Shuai (author), Wolff, Lennard (author), van Zwam, Wim (author), Niessen, W.J. (author), van der Lugt, Aad (author), van Walsum, T. (author)Extracting the cerebral anterior vessel tree of patients with an intracranial large vessel occlusion (LVO) is relevant to investigate potential biomarkers that can contribute to treatment decision making. The purpose of our work is to develop a method that can achieve this from routinely acquired computed tomography angiography (CTA) and...journal article 2023

Almeida Pignatelli de Avillez, Miguel (author)Quasi-satellite orbits (QSOs) are orbits around the smaller primary in three-body systems. The MMX mission (developed by JAXA, to be launched in 2024) will use QSOs to orbit Phobos, before landing on its surface. This work studies the feasibility of using the invariant manifolds of three-dimensional QSOs for designing landing trajectories, using...master thesis 2022

Marynets, K. (author)We study boundedness of solutions to a linear boundary value<br/>problem (BVP) modelling a two-layer ocean with a uniform eddy viscosity in<br/>the lower layer and variable eddy viscosity in the upper layer. We analyse<br/>bounds of solutions to the given problem on the examples of different eddy<br/>viscosity profiles in the case of their...journal article 2022

Giri, Sanjay (author), Thompson, Angela (author), Donchyts, Gennady (author), Oberhagemann, Knut (author), Mosselman, E. (author), Alam, Jahagir (author)This paper presents a hydraulic and morphological analysis of the Lower Jamuna in Bangladesh with a focus on two key bifurcations that are important for stabilization of the Lower Jamuna reach. We used ground measurements, historical data, multispectral satellite images from various sources as well as numerical models. We carried out hydraulic...journal article 2021

Deng, X. (author), Meerman, C. (author), Boelens, T. (author), De Mulder, T. (author), Salles, P. (author), Schuttelaars, H.M. (author)The existence of morphodynamic equilibria of double-inlet systems is investigated using a cross-sectionally averaged morphodynamic model. The number of possible equilibria and their stability strongly depend on the forcing conditions and geometry considered. This is illustrated by considering a rectangular double-inlet system forced by M<sub...journal article 2021

Kooij, Robert (author), Zegeling, André (author)For a family of two-dimensional predator-prey models of Gause type, we investigate the simultaneous occurrence of a center singularity and a limit cycle. The family is characterized by the fact that the functional response is nonanalytical and ehibits group defense. We prove the eistence and uniqueness of the limit cycle using a new theorem...journal article 2021

Gasull, Armengol (author), Geyer, A. (author), Mañosa, Víctor (author)It is well known that the existence of traveling wave solutions (TWS) for many partial differential equations (PDE) is a consequence of the fact that an associated planar ordinary differential equation (ODE) has certain types of solutions defined for all time. In this paper we address the problem of persistence of TWS of a given PDE under small...journal article 2021

Symes, Patrick (author)This thesis aims to provide insight into the conceptual design phase of Tetrahedron B.V. with regards to buckling stability. Currently, Tetrahedron B.V. assumes an effective length factor of one for determining the cross-section profiles of the Tetrahedron Crane. In this thesis, Euler-Bernoulli beams are used to model every member of this crane,...master thesis 2020

Donkers, Paul (author)The goal of this thesis is to create a theoreticalmodel that captures the influence of wind on the horizontal and vertical salinity distribution in an estuary, as well as the dynamics that arise within the estuary. A secondary, numerical model, that uses fewer assumptions, will be developed and analysed. This serves to determine whether the...master thesis 2020

Xia, Jingmin (author), Farrell, Patrick E. (author), Castro, Saullo G.P. (author)When loading experiments are repeated on different samples, qualitatively different results can occur. This is due to factors such as geometric imperfections, load asymmetries, unevenly stressed regions or uneven material distributions created by manufacturing processes. This fact makes designing robust thin-walled structures difficult. One...journal article 2020

Karamitopoulos, P.

Collet, F. (author), Kraaij, R.C. (author)We modify the spin-flip dynamics of the Curie–Weiss model with dissipation in Dai Pra, Fischer and Regoli (2013) by considering arbitrary transition rates and we analyze the phase-portrait as well as the dynamics of moderate fluctuations for macroscopic observables. We obtain path-space moderate deviation principles via a general analytic...journal article 2020

Gasull, A. (author), Geyer, A. (author), Mañosas, F. (author)We show that a family of certain definite integrals forms a Chebyshev system if two families of associated functions appearing in their integrands are Chebyshev systems as well. We apply this criterion to several examples which appear in the context of perturbations of periodic non-autonomous ODEs to determine bounds on the number of isolated...journal article 2020

Bax, Rutger (author)This thesis research has been conducted to analyse the sediment dynamics in the Yangon Estuary, in order to define the cause for the sedimentation in Monkey Point Channel. For years, Yangon Port has been suffering from limited accessibility due to the sedimentation in the channel and currently daily dredging is required in order to let ships...master thesis 2019

van de Kamp, Carsten T. (author)We consider adaptive network models with discrete and continuous state sets obeying dynamical rules that enable application to swarming systems. The 2-state adaptive network contains a supercritical pitchfork bifurcation in the transition between ordered and disordered stationary solutions. We derive an adaptive network model that works on a...bachelor thesis 2019
