The Immersion and Invariance (I&I) wind speed estimator is a powerful and widely-used technique to estimate the rotor effective wind speed on horizontal axis wind turbines. Anyway, its global convergence proof is rather cumbersome, which hinders the extension of the method and proof to time-delayed and/or uncertain systems. In this...

We present a learning method to learn the mapping from an input space to an action space, which is particularly suitable when the action is an optimal decision with respect to a certain unknown cost function. We use an inverse optimization approach to retrieve the cost function by introducing a new loss function and a new hypothesis class of...

Despite the progress in the field of longitudinal formations of automated vehicles, only recently an interpretation of longitudinal platooning has been given in the framework of disturbance decoupling, i.e. the problem of making a controlled output independent of a disturbance. The appealing feature of this interpretation is that the...

Gaseous ammonia (NH<sub>3</sub>) recovered from residual waters may be used as a fuel in solid oxide fuel cells (SOFCs) to generate electricity without emission of undesirable oxidised nitrogen species. NH<sub>3</sub> can be directly recovered from water as a gas by vacuum membrane stripping (VMS), which also results in the evaporation of...

Collaboration between the Global South and Global North is inevitable. It can work. It can be emphatic, effective, and more equal. However, there is a deeply embedded history of colonialism involving power asymmetries that give rise to the dismissal of value systems, which pervert this type of collaboration from being truly realised. Hence,...

Acidizing is a widely used technique for intensification of geothermal wells. At certain conditions, acid injection results in a formation of highly conductive channels, e.g. wormholes. The associated rock matrix dissolution is highly nonlinear and may influence the fluid flow as well as rock properties. Wormhole patterns and breakthrough time...

Due to increasing cost pressure, disturbances from customs and an opportunity seen in reducing costs by increasing the procurement and construction in the Far East, Damen Shipyards Gorinchem is changing the requirements for its supply chain. Changes to the supply chain however not only inflicts a large number of stakeholders, but the cost...

Optical microscopes are fundamentally limited to a resolution of several hundreds of nanometers by the diffraction of light. Single-molecule localization microscopy (SMLM) circumvents this limit by sparsely exciting fluorescent molecules at different time instances. Single molecules can subsequently be localized with improved precision over the...

In this thesis a proof-of-principle demonstration is developed that uses the heat flux between a probe and a sample as a proxy for their separation. The proposed architecture uses a probe that consists of a bilayer cantilever with an attached sphere at its free end. The deflection of the cantilever that is caused by the heat input is measured...

We study the acceleration of the finite element method (FEM) simulations using machine learning (ML) models. Specifically, we replace computationally expensive (parts of) FEM models with efficient ML surrogates. We develop three methods to speed up FEM simulations. The primary difference between these models is their degree of intrusion into the...

Patients with a Fontan circulation have a diminished life expectancy of only 30-40 years old. A mechanical circulatory assist device can potentially increase their life expectancy and quality of life. Given the complexity of the anatomy and physiology of the Fontan circulation, design of a safe and effective mechanical assist device is a...

In drinking water treatment plants, multiphase flows are a frequent phenomenon. Examples of such flows are pellet-softening and filter backwashing where liquid-solid fluidisation is applied. A better grasp of these fluidisation processes is needed to be able to determine optimal hydraulic states. In this research, models were developed, and...

Although inland waterways (IWW) are considered one of the most reliable transport modes, it is very vulnerable to climate change, more than other transport modes such as rail and road transport. The inland waterway transport (IWT) performance strongly depends on the available water depth in the waterway, which is related to the river discharge....

In this work, we present the results of a preliminary uncertainty quantification and sensitivity analysis study of the Molten Salt Fast Reactor (MSFR) behavior at steady-state performed by applying a non-intrusive Polynomial Chaos Expansion (PCE) approach. An in-house high-fidelity multi-physics simulation tool is used as reactor reference...

The Netherlands aims at reducing natural gas consumption for heating in the housing sector. Although homeowners are responsible for replacing their heating systems and improving dwelling insulation, they are not always able to make individual decisions. Some projects require group decisions within and between buildings. We use an agent-based...

OCI Nitrogen, one of Europe's largest fertilizer producers, is investigating the extent to which it is possible to take targeted measures at an early stage and stop the development of major hazard accident processes. An innovative model has been developed and recently explained and elaborated in a number of publications. This current paper...

To reduce the Urban Heat Island (UHI) effect Green Infrastructure (GI) is seen as a key measure. Though, often the need for water to evaporate is neglected. This study focuses on showing the effects of irrigation and increased soil moisture contents on GI within urban areas to reduce the UHI-effect. ENVI-met, a micro-climate model, is used to...

In the Netherlands, the frequency and severity of extreme rainfall events are expected to increase. This can result in severely detrimental effects. It is complicated for municipal actors to effectively manage these events, as it requires judgement on probabilities, costs, and uncertain impacts. As a result, obtaining scientific knowledge...

Several initiatives are being developed to shift the current paradigm in Air Traffic Management (ATM) from the tactical-based approach to more strategic-based coordination of flights. This transformation of the ATM system relies on the improvement of predictive models that predict the 4D-trajectory of an aircraft. Previous studies primarily...

Nowadays cycling rates in most European cities are increasing, while many governments are looking for ways to integrate cycling into the daily lives of citizens not only as a leisure activity but also as an official means of transport. At the same time, a large part of the population itself aims to influence decision-makers and urban planners to...
