Development of the autonomous vehicle has been a trending topic over the last few years. The automotive industry is continuously developing Advanced Driver-Assistance Systems (ADAS) that partially take over the driver’s workload. This has resulted in an increase in vehicle safety and a decrease in fatal crashes [1]. Full vehicle autonomy has not...

Existing scoliosis braces preclude spinal movement for activities of daily living, which reduces the willingness to wear the brace and treatment success. This work develops a scoliosis brace that meets corrective requirements while retaining patient mobility.
The primary compliance vector (PCV) captures the predominant kinematic degree of...

In 20 years, from 1996 to 2016, global cumulative container port throughput had an average annual growth rate of 6.3%. Furthermore, the average global transshipment incidence increased from 11% in 1980 to a stable 27% in 2017. This change in transshipment market dynamics has led to opportunities for potential port investments or disinvestments....

To increase the total wind farm power output, the wind farm layout needs to be optimized. The power output of a wind turbine depends on the incoming velocity, while the velocity is influenced by the wake of the upstream wind turbines. Wind Farm Layout Optimization (WFLO) problems makes use of the so called low fidelity wake models, which...

This research concerns the problem of scheduling aircraft maintenance tasks, that must be carried in multiple maintenance checks to keep the aircraft airworthy. During this research the allocation of maintenance tasks to their maintenance opportunities is referred to as the task allocation problem. It is a complex combinatorial problem that is...

Model-based evolutionary algorithms (MBEAs) are praised for their broad applicability to black-box optimization problems. In practical applications however, they are mostly used to repeatedly optimize different instances of a single problem class, a setting in which specialized algorithms generally perform better. In this paper, we introduce the...

Currently, KLM's apron processes work in separate silos and there is only minimal integration. The result is that processes tend to work to a local optimum instead of a global optimum. A Transport Logistic Control Tower is a centralized information hub from which integral decisions can be made which could benefit the overall turnaround process...

Vibrations are experienced as unwanted dynamic motions and the industry takes a lot of care to reduce these motions to improve comfort and to increase vehicle component durability. The properties of rubber, being generally soft while showing large inherent damping, makes the material a perfect choice to use in vibration isolators. To minimize...

The subject of this master thesis is the development of a design tool to help Vuyk Engineering Rotterdam B.V. arrange the machinery spaces (engine room, switchboard rooms, separator rooms) aboard their vessels early in their design process. It applies the field of automatic design generation to a step in Vuyk’s design process to save time and...

In the Netherlands, wind power has the highest potential for future development compared to alternatives such as solar PV and biomass. The intermittent nature of the wind power resource calls for novel approaches to supply and demand management, as well as power quality assurance. Energy storage technologies allow for the separation between...

In the automotive industry automation is popular and every year car OEMs advance their technology to be able to drive autonomously. Longitudinal control of the vehicles is an important part of the complete autonomous driving system. The difficulty of this control problem lies with changing longitudinal dynamics and the lack of full-state system...

Wind Power Producers (WPP) incur a negative result through mandatory participation on the balancing market. This study analyzes the performance of multiple improved offering strategies for a WPP offering both on the day-ahead market and the balancing market. It does so on revenue, as well as its impact on the grid and electricity market as a...

Nowadays, reinforcement learning algorithms on Markov decision processes (MDPs) face computational issues when the state space is large. To reduce this state space of a MDP several state aggregation, or clustering, methodologies have been applied. Recently, a new clustering algorithm has been proposed that is able to cluster states from a single...

The area surveillance problem is the problem of surveying a known or an unknown area with the main purpose of detecting objects. This thesis will tackle the problem of how to employ a group of mobile-sensors for surveying an unobstructed area in an optimal manner. The mobile-sensors should make use of their onboard computers and they should...

In modern ASML machines optical components play an important role in the lithography process. EUV light is transported from the source to wafer by reflective optics. These mirrors are subjected to large thermal loading, as a large portion of the reflected light is absorbed in the mirror structure. The portion of the absorbed light is strongly...

The utilization of deep geothermal resources for combined heat and power generation in Germany has increased slowly but continuously during the last years. Due to the growing technical readiness, the focus is now shifting from the first proof of concepts to optimizing the performance of existing plants. One promising approach is the further...

To increase performance of air-to-air missile guidance, a novel guidance law is developed using reinforcement learning methods. This guidance law is based on behavior obtained from optimal control methods and subsequently aims to approximate its performance. The study compares the developed guidance law to a traditional guidance law and optimal...

In the European Union Road freight transport volume is expected to grow 78% between 2000 and 2030, which results in more trucks on the road network. The worldwide estimated trend shows an increase of 150 million freight vehicles and an increase of 240 million passenger vehicles. The growth of both vehicle classes will have a major impact on the...

The purpose of this research is to investigate the effects of individually established buffer times, based on historical delay data, on the robustness of an operational stand and gate allocation schedule. Using flight schedules and the structural lay-out of Amsterdam Airport Schiphol, a stand and gate allocation model is created using BEONTRA...

The Delft University of Technology is developing an MDO tool for the conceptual design of transport aircraft. However, the current program is not able to investigate the influence of the undercarriage design on the weight, drag and geometry of transport aircraft. This research proposes a new design method for the undercarriage, for which a new...
