The idea of capturing an asteroid has gained more and more attention in recent years, sparked by rapid technological development and the growing general interest into the subject, both by scientists and commercial parties. The focus of this thesis project lies on transferring a near-Earth asteroid (NEA) from its original orbit to a safe, stable...

The world is faced with two concurrent trends. The first is the growing demand for air travel in the long term. The second is the need to cut aircraft emissions due to environmental goals and ambitions set by authorities. Fully-electric aircraft are currently infeasible due to the limited battery specific energy and power. Hybrid-electric...

This research aims to develop a method to create a wind farm layout that is robust against the uncertainty source, the inter-year variation of Weibull parameters and wind direction sector probabilities. A wind farm layout optimisation problem under uncertainty corresponds to optimisation under uncertainty (OUU), which is computationally...

In order to make access to space cheaper, the first stage of a launcher can be recovered. For this research, different options are investigated to make the cost per flight cheaper. Two vehicles are investigated going to two different orbits. The results show that recovering the complete stage is better for vehicles that have a lower separation...

In this thesis project, it is investigated to what extent the energy consumption of an electric aircraft can be improved by using a variable pitch and RPM propeller, including energy recuperation during the descent, with respect to a constant pitch propeller. The largest percentage of total mission energy saved using the variable pitch propeller...

The structural properties of a composite laminate can be tailored by allowing the fibres to vary their orientation within the individual plies. This class of composites is termed variable stiffness and they are able to enhance the structural performance over traditional laminates by redistributing the internal load of the structure. Therefore,...

Destructive consequences of trapped space charges within HVDC coaxial cable insulation, such as accelerated aging, degradation, and breakdown, are some of the most significant challenges that manufacturers and users usually come up with. Pulsed Electro-Acoustic (PEA) method is a widely-used method for space charge detection and measurement, in...

The thesis focusses on the effects that an intercooler (IC) and an inter­turbine burner (ITB) have on the cycle performance of a UBPR engine. The IC is located between the low­pressure compressor (LPC) and the high­pressure compressor (HPC). It exchanges heat between the core flow and the bypass flow reducing the temperature in the core flow....

Waste-to-energy is the process of generating energy from municipal waste. The most conventional energy recovery method is incineration, which takes place at a waste-to-energy plant. The incoming waste is collected in a bunker, where an overhead crane stacks and mixes the material before feeding it to the furnaces. The more homogeneous the waste...

The present research performed a design exploration of fast ferry catamarans with hard chined demihulls sailing in irregular head waves, to analyse the influence of the demihull shape (without appendages) on wet deck slamming, and identify the geometrical properties and their trends to reduce it. Wet deck slamming is a phenomenon known to cause...

Over the last decade, interest in deep-sea mining of Polymetallic Nodules (PN) has reignited. It is driven by an increasing demand of metals that are critical for the digital economy and modern technologies such as batteries. Methods for resource estimation of PN are known and commercially available. There is however no standard method of a...

Minimum-time optimisation has been used extensively in motorsports, such as Formula One racing. Using minimum-time optimisation, the ideal racing line as well as control strategies such as braking strategies can be found. This is interesting, as Reijne et al have shown that cyclists apply diverse strategies, specifically during a descent [1]....

The maritime inventory routing problem (MIRP) is a tactical and operational planning problem, that takes an integrated view on ship scheduling and inventory management for bulk products. Given production and consumption levels during a predetermined planning horizon, the problem aims at finding delivery schedules with minimal travel costs, such...

In the field of radio astronomy the Ultra-Long Wavelength (f < 30MHz) band is unique, it has been studied for nearly a century yet it is still almost completely uncharted. Due to the reflective properties of Earth's ionosphere this band is nearly completely inaccessible for ground-based observatories, which can only receive frequencies down...

This thesis addresses the capabilities and challenges of automated design approaches, specifically for ap-plication in which a combination of heat transfer and flow is needed. The objective is to use automateddesign approaches from literature and to identify the bottlenecks.For this purpose, an industrial thermal-fluid airshower is designed,...

This paper addresses the airline centred Arrival Sequencing and Scheduling problem aimed at the smart distribution of arrival delays, considering the explicit preferences from users. We consider the scenario in which actions are executed solely in the en-route phase with the available leeway present in the<br/>current ATM system. The arrival...

In this thesis we look at three different algorithms within the field of phylogenetics and create a proof of concept for using machine learning to improve the algorithms. The problems are the maximum agreement forest problem, the hybridization number problem and finally the tail move problem. A study of the problems show that they can all...

Flash calculations are used for the dynamic simulation of vapor-liquid phase equilibria (VLE) in many chemical processes. When used to predict the composition of mixtures in VLE, the repeated applicatino of these flash calculations, particularly in dynamic cases can cause small inaccuracies to cascade. One way to prevent this, is to have strong...

This research aimed to design a new bridge for the city of Rome, Italy, through the support of modern optimisation and decision-making processes that can be implemented to make informed choices regarding aesthetic performance, structural firmness, and environmental impact. The bridge’s design was carried forward considering the city’s plans for...

Shape has long been an important parameter in improving the internal comfort of buildings and reducing energy demand. This can be seen from historical vernacular architectural typologies, like igloos, which have minimal thermal loss surface to provide a comfortable internal climate.  Using a shape factor to reduce the...
