Sensitivity of the seismic response of monopile-supported offshore wind turbines to soil variabilityPanagoulias, S. (author), de Winter, C.M.A. (author), Navalkar, S.T. (author), Nernheim, A. (author)The expansion of the offshore wind industry in areas with high seismicity has led to engineering challenges related to the design of the offshore wind turbines (OWTs). Monopiles, i.e., tubular steel piles of large outer diameter, low aspect ratio (penetration depth over outer diameter), and relatively thin pile wall, are traditionally the...journal article 2023

Lottering, Yara (author)This Bachelor End Project Thesis is about creating parallel variants of time-dependent methods. To achieve this, the time-dependent problem is formulated as a large system of linear equations that is solved iteratively. This linear system is determined from the time-dependent linear heat equation in 1D that all the analysis is about. The...bachelor thesis 2022

van Ooijen, Cas (author)This thesis is about the wave equation. The wave equation describes waves that propagate through a certain medium. The solution of the wave equation is a mathematical description of what that wave looks like. There are many fields of study where the wave equation is used to model processes that behave like travelling waves. For instance, a...bachelor thesis 2022

in 't Veld, Niels (author)Optimal control is a paradigm for solving optimization problems involving dynamical systems, which are to be controlled. It is able to solve fish harvesting problems, in which we want to optimize harvesting out-take by considering fishing as a control function that acts on the state of the dynamical system, which represents the growth of fish...master thesis 2022

Rosado Bailon, Gisela (author)The safety of a commercial aircraft is a factor to consider from the early stages of its design to guarantee that this one's structure can protect the occupants inside in a low-speed crash. In an aircraft's primary structure such as a fuselage, where the occupants and cargo should be protected, the design regulations imposed by the EASA have...master thesis 2022

Tang, Jiuyang (author), Li, Liangtao (author), Zhang, Kouchi (author), Zhang, Jing (author), Liu, Pan (author)Ultrasonic wedge bonding of aluminum (Al) wires is a widely applied interconnect technology for power electronic packaging. The joint quality of the wedge bonding is mainly affected by the process parameters and material properties. Inappropriate process parameters will lead to failure modes such as chip surface pit, metal layer peeling off,...journal article 2022

Caglar, Baris (author), Broggi, G.C. (author), Ali, Muhammad A. (author), Orgéas, Laurent (author), Michaud, Véronique (author)Knowledge of permeability of fibrous microstructures is crucial for predicting the mold fill times and resin flow path in composite manufacturing. Herein we report a method to rapidly predict the permeability of 3D fibrous microstructures. Our method relies on predicting the permeability of 2D cross-sections via deep neural networks and...conference paper 2022

Lager, I.E. (author), Stumpf, Martin (author), Vandenbosch, Guy A.E. (author), Antonini, Giulio (author)The late-time evaluation of electromagnetic (EM) field quantities yielded by convolution integrals that combine Green's functions available at discrete time samples and strictly causal excitations is critically revisited. A typical situation is used for tracing the causes of the divergent late-time behavior that is often experienced. A...journal article 2022

Bonfanti, Benedetta (author)Thyroid hormones are fundamental in the development and function of the human body. They are produced by the thyroid and their concentration is regulated by a negative feedback loop involving also the hypothalamus and the pituitary. Many studies have shown that each individual has a unique HPT axis set-point, which means that everyone has his or...master thesis 2021

van de Ven, Emma (author)Acute Ischemic Stroke (AIS) is an abrupt onset of a focal neurological deficit due to the occlusion of a cerebral artery caused by thrombosis or embolism. According to the World Health Organization, stroke is the second leading cause of death in the world. One of the available treatments is the aspiration thrombectomy, where a negative pressure...master thesis 2021

Hielkema, Marleen (author)This research is mainly about optimising compartment models for COVID-19 and then using them for different applications that can be used to consult authorities. A compartment model describes the dynamics of a disease by implementing differential equations for the different states that belong to that disease. This is done using parameters which...bachelor thesis 2021

Frima, Erik (author)In (mathematical) physics one can encounter problems with a fase change, the so called Stefan problems. Numerical methods to solve these problems often use a level-set function which indicates the distance to the fase boundary. Problems can arise in the medial axis points of the zero set. Therefore it can be usefull to calculate this medial axis...bachelor thesis 2021

Markensteijn, A.S. (author)Energy systems are vital in modern society, and reliable operation is crucial. Multi-carrier energy systems (MESs), which couple two or more single-carrier systems, have recently become more important, as the need for sustainable energy systems increases.

Kleynen, Wouter (author)A black hole is an object in space where the pull of its gravity is so strong<br/>that no light can escape. This notion gives rise to the phenomenon called<br/>gravitational lensing which is the effect where light is being bent by a massive<br/>object, in our case a black hole. With these two concepts in mind we are<br/>able to formulate the...bachelor thesis 2021
