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...

Interobserver reliability is a problem in behavioural studies. In order to increase the interobserver reliability, a formal checker is used to study behaviour. Together with a clear ethogram of basic behaviours, this tool can be used to automatically check for more complex behaviours and thus reducing the risk of biases introduced by human...

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 technology used in health care is one of the fastest developing fields in Precision Engineering. The main focus in this field is on the development of steerable, small dimensioned instruments. Using these, surgeries can be done with minimal damage to the patient, shorter hospital stay and more aesthetical healing.
From the medical 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...

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...

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...

Correction techniques, such as tangential iterative projections (TIP), were developed to reconstruct the image for the whole field of view. However, due to the three dimensional nature of biological tissues, induced aberrations are different throughout the field of view. This Master of Science thesis shows the development of four algorithms....

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...

The use of the Classical Laminate Theory (CLT) is limited to laminates where all the fibres in a ply are oriented in the plane of the laminate. In some applications, it is possible that the plies will start at the bottom of a laminate and end at the top of the laminate. This means an inclination is added to the plies, which creates an extra...

The energy transition is the transformation of the energy system and the main energy resources from fossil-based to zero-carbon resources. Decarbonization of the end-use sectors and the integration of the variable renewable energy (VRE) sources are the main challenges of the transition. In the Netherlands, the heat sector depends on natural gas...

The turbulent lifted Dutch natural gas jet diffusion flame in cold co-flowing air is widely used in gas turbine operation and subject of the current investigation. In striving to clean and sustainable combustion, adding hydrogen to the Dutch natural gas (DNG) fuel and CO2 in the coflow is promising. Objective of this investigation is to study...
