This thesis explores the feasibility of aerocapture manoeuvres at Venus, focusing on the challenges for an autonomous Guidance and Control (G&C) system, including a partial Navigation system simulation. Aerocapture leverages atmospheric drag for orbit insertion and presents a cost-effective alternative to traditional propulsive methods. The...

The data assimilation process for geothermal reservoirs often relies on well data which primarily offers insights into the immediate vicinity of the borehole. However, integrating geophysical methods can provide valuable information beyond well proximity, possibly enhancing reservoir predictions. Electromagnetic methods can be sensitive to the...

In this paper, we discuss our novel approach to support mixed-direction shunting in the planning domain for tree-like shunting yards. We explain how we used numeric fluents to improve an existing PDDL domain to support such actions. We elaborate on the underlying conceptual model of our domain and argue how does it accurately represent<br/...

The transverse flute can be studied on many aspects. In this thesis the sound waves that can be generated inside the flute are studied on their shape and frequencies. To achieve this, two mathematical models of the sound waves inside a flute are developed. To develop these models, solutions to the second dimensional wave equation are calculated...

A numerical model is developed in Simulink to simulate transient alkaline electrolyzer operation. The model is built to simulate a large scale hydrogen plant in Rjukan, Norway. The model is based on physical relations where available, some plant-specific data is modeled using empirical equations. The model describes the anodic and cathodic...

The hazards of unexploded ordnance threaten the increasing marine construction activities nowadays, which increases the importance of unexploded ordnance detection. Research has shown that transient electromagnetic methods can successfully be used to detect unexploded ordnance on land. New equipment is being developed to make marine unexploded...

The goal of this thesis is to create a theoreticalmodel that captures the influence of wind on the horizontal and vertical salinity distribution in an estuary, as well as the dynamics that arise within the estuary. A secondary, numerical model, that uses fewer assumptions, will be developed and analysed. This serves to determine whether the...

Option valuation is one of the more applied areas of mathematics. Options are financial derivatives whose value depends on the value of an underlying asset. They are frequently used in hedging to minimize the risk when trading in the underlying stock and therefore require accurate pricing. Though quite some research has been conducted on...

In the past years, climate change has caused an increasing number of extreme weather events. In the Netherlands this is, for instance, reflected by the growing amount of extreme rainfall events. This creates big issues for water management authorities like water boards. Water boards are often responsible for local streams, that cannot handle the...

The Wanda software package developed by Deltares can used for simulating both steady state and transient fluid flow in pipeline systems. Steady state simulations are used for initial system design and transient flow simulations are used for doing water hammer analysis in pipeline systems. For both types of simulations a system consisting of both...

In the past decades the understanding of fracture of ductile material has increased substantially. Research has shown that the onset of fracture highly depends on the full state of stress inside the material. Better understanding of fracture resulted in more advanced and complex fracture models being conceived, allowing researchers to predict...

In the Rhine-Meuse Delta in the Netherlands, deep scour holes can develop very suddenly. The holes may form a potential risk for the stability of surrounding riverbanks, dikes, bridges, tunnels and buildings. A scour hole can mostly be the result of two conditions: local changes in hydrodynamical conditions or local changes in erosive capacity...

Researchers at Delft University of Technology have recently developed an algorithm for optimizing noisy, expensive and possibly nonconvex objective functions for which no derivatives are available. The data-based online nonlinear extremum-seeker (DONE) was originally developed for sensorless wavefront aberration correction in optical coherence...

Due to increasing marine traffic intensity on inland waterways the interaction between ships and banks is becoming more of a problem. Bank effects make ship manoeuvring more difficult and rivers need to be protected against ship-induced currents and waves. This thesis contributes to the development of a new method that simulates these ship-bank...

When looking at domains with several building densities, the resulting average concentrations caused by traffic when unknown, are often linearised between known building densities. To verify if this assumption is correct, several cases of street canyons with intersections, are simulated using the DALESURBAN model. The traffic is represented by a...

Pigs (pipeline inspection gauges) are free moving piston-like devices, that are used for inspecting or cleaning pipelines in for example the oil and gas industry. Here they are used for onshore and offshore pipelines, where they are propelled by the production fluids. A better control of the velocity of the pig in the pipeline can be achieved by...

This thesis discusses the valuation of embedded options in insurance liabilities using radial basis functions. For insurance companies, the valuation of embedded options is an important topic within risk management. This valuation can become too computationally heavy when nested Monte Carlo simulations are used. To overcome this computational...

With fuel oil the main driver for operational expenses, increasingly stringent regulations on emissions of ships and a growing environmental awareness throughout the industry, the concept of Wind-Assisted Ship Propulsion (WASP) presents itself as a means to reduce fuel consumption. Though a promising concept, the performance prediction of a wind...

The influence of laminar-turbulent transition on a propeller blade’s performance has been investigated in this study, both numerically and experimentally. The computational fluid dynamics (CFD) is performed using the TAU code developed by the German Aerospace Center, as well as an existing propeller lifting-line code. The laminar-turbulent...
