Performance of set based fault detection is highly dependent on the complexity of the set bounding methods used to bound the healthy residual set. Existing methods achieve robust performance with complex set bounding that narrowly define healthy system behavior, yet at the cost of higher computation times. In this thesis a major improvement is...

The scarcity of historical financial data has been a huge hindrance for the development algorithmic trading models ever since the first models were devised. Most financial models assume as hypothesis a series of characteristics regarding the nature of financial time series and seek extracting information about the state of the market through...

This thesis provides a theoretical framework for the arise of stop-and-go waves in platoons of Human-driven Vehicles (HVs) on a ring road topology. Possibilities and limitations for traffic control and suppression of such waves via a single Autonomous Vehicle (AV) are considered. Being HVs prone to show string instability, i.e. a type of...

The goal of this report is to study the way in which female university students (aged 18 to 25) deal with their moods during their menstruation, and to use this information to design a product to help them deal with their negative moods in a healthy way, by using resilience-focused mood-regulation strategies. Literature research and the field...

The ability to locate specific objects within images is an essential step in various computer vision based engineering applications. Image segmentation is the task of dividing an image into "segments" that are uniform as well as homogeneous with respect to some characteristics, for example grey tone or texture as in Haralick et al. This thesis...

The current needs of sustainable mobility lead to the electrification of transport industries, which require innovative products. The use of fuel cell electric vehicles (FCEVs) on a commercial basis depends on the development of hydrogen storage devices, which must be reliable and cost-effective. For the design of high safety composite pressure...

A fault-tolerant controller is presented that is able to recover a quadrotor from an upset condition in the case of a single rotor failure. With only 3 rotors the quadrotor is not fully controllable anymore, however by using precession the quadrotor can be made controllable again in roll and pitch. A step-by-step recovery strategy is proposed in...

Using an idealized width-averaged model, the influence of spring-neap cycles on the transport and trapping of suspended fine sediment in tide-dominated estuaries is investigated. To this end we introduce a multiple time scale expansion. This provides a mathematically sound argument for treating the fast ebb-flood cycle and the slow spring-neap...

Using a data-driven approach, a heterogeneous populated agent-based model of an airport security checkpoint is calibrated and validated. It is found that average performance using the model can be replicated to a sufficient degree. The heterogenous population could become useful when different passenger fractions - with different performance per...

One-Shot Neural Architecture Search (NAS) is a promising method to significantly reduce search time without any separate training. It can be treated as a Network Compression problem on the architecture parameters from an overparameterized network. However, there are two issues associated with most one-shot NAS methods. First, dependencies...

Currently used imaging methods in Atomic Force Microscopy (AFM) including the use of a Lock-In Amplifier or a Phase-Locked Loop, are suboptimal. In this report, the image resolution in AFM is improved by detecting the tip-sample interaction using complete measurements of the input of the cantilever and its measured deflection. Two methods are...

Low-thrust trajectories can benefit the search for propellant-optimal trajectories, but increases in modeling complexity and computational load remain a challenge for efficient mission design and optimization. An approach for developing models utilizing Gaussian Process (GP) regression and classification is proposed to perform computationally...

For large-scale system with tens of thousands of states and outputs the computation in the conventional Kalman filter becomes time-consuming such that Kalman filtering in large-scale real-time application is practically infeasible. A possible mathematical framework to lift the curse of dimensionality is to lift the problem in higher dimensions...

The growing share of renewable electricity generation poses a balancing challenge on the electricity grid and thus increases probability of for congestion on the electricity grid. On the supply side, flexibility can be built into the system. One option for a market to avoid congestion is the redispatch market, which is the way of solving...

Recent years the Netherlands have been shocked by a series of earthquakes. Normally an earthquake would be considered as a natural hazard, however extracting gas induces these earthquakes. Whenever a hazard is induced, it is perceived as man-made and therefore controllable. This leads to differences in risk acceptance in relation to natural...

Joint kinetics measured during level walking demonstrates that the main source of energy occurs around the ankle joint, i.e. a large power burst during push off. This power burst can be divided into two mechanisms; pre-emptive push off and a push off to accelerate the leg into swing. This division is marked by the contralateral initial contact,...

Traditional centralized power plants have limited ability to adapt to the varying power demands caused due to the increasing deployment of renewable energy sources. For power grids, willing to increase the use of renewable energy and thereby decrease the energy bills, demand side energy management could act as an effective solution. Demand side...

Greenhouse gas concentrations are ever increasing in the Earth's atmosphere, causing the global temperature to have reached over a 1.0 degree Celsius increase relative to pre-industrial levels. A further increase in this temperature can have disastrous effects on our society, thus the increase in greenhouse gases must be attenuated....

The Atomic Force Microscope is a type of high-resolution Scanning Probe Microscope where the image resolution has been demonstrated to be 3 orders of magnitude better than the optical diffraction limit. Directly observing individual protein molecules in action at high spatio-temporal resolutions has long been a holy grail for biological science....

The conducted study investigates the potential of a newly released multi-phase solver to simulate atomization in liquid rocket injectors. The "VOF-to-DPM" solver was used to simulate primary and secondary atomization in an air-blast atomizer with a coaxial injector-like geometry. The solver uses a hybrid Eulerian/Eulerian-Lagrangian formulation...
