Wassenaar, Arjen (author)The use of geometric anti-springs (GASs) in MEMS accelerometers can not only boost the sensitivity through the static balancing effect, it also introduces the capability to tune the stiffness post-manufacturing by adjusting the balancing force. This paper addresses the challenge of mechanically fine-tuning the stiffness to create the potential...master thesis 2024

Sennema, Erik (author)Intrusion detection systems (IDSs) are essential for protecting computer systems and networks from malicious attacks. However, IDSs face challenges in dealing with dynamic and imbalanced data, as well as limited label availability. In this thesis, we propose a novel elastic gradient boosting decision tree algorithm, namely Elastic CatBoost...master thesis 2023

Koshy Cherian, Jeswin (author)Drifting, a specialized form of sideslip control, involves intentionally inducing and maintaining a state of oversteer for lateral sliding of the vehicle. While previous research has primarily focused on autonomous drift control, the integration of the driver in the control loop remains largely unexplored. This thesis aims to explore how a...master thesis 2023

Fabre, Elodie (author)Facing the neo-liberalisation of the city, "the furtive monument" is a path across the city, combining programs of the body, the mind and the politics, in order to reach a state of empowerment. Based on a situationist drift, architectural interventions transform the way the city of Rotterdam is experienced, not based on profit but based on...master thesis 2023

Meijer, Stan (author)Abstract—This paper proposes a Nonlinear Model Predictive Control (NMPC) application for automated drifting, with exper- imental verification on a standard production vehicle, without hardware modifications. The controller stabilizes the vehicle on a high sideslip angle, which implies an equilibrium condition beyond tyre friction limits. The...master thesis 2023

Bontje, Floor (author)When a person makes a decision, it is automatically accompanied by a subjective probability judgement of the decision being correct, in other words, a (local) confidence judgement. Confidence judgements have, among other things, an<br/>effect on justifications of future decisions and behaviour. A better understanding of the metacognitive...master thesis 2023

Weiler, Marnix (author)During ‘float-out’ installation of export cables, the cable is pulled to shore while floating, supported by inflatable floaters. Understanding the hydrodynamic behaviour of these cable-floater-systems (CFS’s) is important, to be able to relate the hydraulic environment to the cable stresses and determine the maximum allowed hydraulic conditions...master thesis 2023

Kanniainen, Konsta (author)Various techniques have been studied to handle unexpected changes in data streams, a phenomenon called concept drift. When the incoming data is not labeled and the labels are also not obtainable with a reasonable effort, detecting these drifts becomes less trivial. This study evaluates how well two data distribution based label-independent drift...bachelor thesis 2023

André, Baptiste (author)When deployed in production, machine learning models sometimes lose accuracy over time due to a change in the distribution of the incoming data, which results in the model not reflecting reality any longer. A concept drift is this loss of accuracy over time. Drift detectors are algorithms used to detect such drifts. Drift detectors are important...bachelor thesis 2023

Cador, Andrei (author)Full vehicle automation requires complete control over all driving scenarios that can be encountered on roads in order to ensure passenger safety at all times. This extends to dangerous situations such as losing control on slippery surfaces, commonly known as drifting. This work aims to make a step toward ensuring passenger safety in these...master thesis 2022

Boreel, Noor (author)In the eighteenth century, the city centre of the metropolis of London was the most chaotic due to its immense industries and excessive noise and smell. This sensorial overstimulation brought and still brings potential unsustainable health and well-being effects on its urban participants. <br/><br/>This research explores the redefinition and...master thesis 2022

Wang, Wenhui (author)Data drift refers to the variation in the production data compare to the training data and sometimes the machine learning model would decay because of it. Some machine learning models face the problem when in production: they receive drift data while there’s no ground truth to evaluate model performance, thus no way of determining the...master thesis 2022

Kramer, Jelle (author)A vehicle that is travelling at high sideslip angles can still be controlled by drifting. Implemented into a vehicle, this phenomenon could lead to increased vehicle safety and performance. Additionally, it could lead to higher acceptance rates of autonomous driving.<br/>In this work a three state vehicle model is used. Using this model,...master thesis 2022

Hoogewerf, Guus (author)Three-component seismometers deployed on the sea bed have been used for many years. These so-called ocean bottom seismometers (OBS) are used to register both compressional and shear waves. The recorded seismic information is used to enhance our understanding of areas of interest located offshore, like hydrocarbon reservoirs, mid oceanic ridges,...master thesis 2022

Nijsse, Hannah (author)Low-field MRI is susceptible to temperature changes in magnet temperature, resulting in time-dependent inhomogeneities. This causes time-dependent phase shifts in the measured signal, leading to image distortions. In this project, a method is proposed to interleave short magnetic field (B0) mapping sequences in the target image acquisition for...master thesis 2022

van Houten, Aris (author)Compliant mechanisms and decoupled parallel mechanisms are topics of high interest. The combination has been manifested for lower-mobility mechanisms, yet not attempted for higher degrees of freedom. The scarcity is countered by designing a decoupled compliant spherical parallel mechanism (DCSPM), having three independent rotational degrees of...master thesis 2021

Huang, Ziyang (author)To meet energy demand towards a low-carbon future, the global market demand is growing for metals such as cobalt and nickel which are major elements in batteries. Polymetallic nodules, which are formed on abyssal plains at depths ranging from 4 to 6 kilometres and are distributed in high abundance on the top of the seabed, contains several times...master thesis 2021

Liu, Jordi (author)Within a Protoplanetary disk (PPD), planets form from micron sized particles, but what are the processes taken for planet formation? How does the evolution of micron sized particles via settlement and coagulation lead to the gigantic planets as the ones in our Solar System? This thesis explores the planet formation process of pebble accretion...master thesis 2021

Daan, Boris (author)For steel flexures, complex geometries are required to reach high support stiffness and limit axis drift over large ranges of motion. These complex flexures are expensive and difficult to manufacture. This paper presents a method of designing short, polymer wire flexures with high support stiffness and modelling their axis drift using a novel...master thesis 2020

Bakker, Floor (author)To exploit its socio-economic functions, engineering measures are regularly applied in estuaries. Estuaries are, however, known to be very complex systems. Stemming from this complexity is the generation of a so-called estuarine turbidity maximum (ETM), which poses great siltation problems to the engineering measures. An engineering measure,...master thesis 2020
