The influence of location on the profitability of a charging station

With the increasing number of electric vehicles on the road, the routing problem has become more complex. As charging electric vehicles takes longer than fueling non-electric vehicles, congestion can occur at charging stations. This might lead to the shortest route not being the fastest route, due to long waiting times at the stations. By...

Using reinforcement learning for finding the optimal quantum annealing schedule

For NP-hard optimisation problems no polynomial-time algorithms exist for finding a solution. Therefore, heuristic methods are often used, especially when approximate solutions can be satisfactory. One such method is quantum annealing, a method where some initial Hamiltonian is slowly perturbed to anneal towards a problem Hamiltonian. The...

Power flow control in a substation of a wind- and solar farm: Design of an Optimisation Unit Considering a System's Physical Boundaries and Technical Constraints

The goal of this graduation project was to design a state-of-the-art central farm controller. The designed central farm controller distinguishes itself from prevailing controllers by including a subsystem (the optimisation unit) that contributes to an improvement in power transmission effciency, decrease in maintenance costs and an increase in...

Taxis Dispatch: Minimizing waiting times by maximizing coverage

In this thesis, we investigate whether maximizing the coverage of taxis can be beneficial when the goal is to minimize the waiting times of the clients. When dispatching taxis, often only current requests are taken into account and not future ones. We examined how beneficial it can be to take coverage into account. For taxi companies it is...

Camera Positioning and Vision-based Fall Detection

Elderly care residences often have falling incidents, sometimes with dire consequences. This project aims to implement a method for detecting when people fall, an issue that has seen much research and practical implementations already. In contrast to other work, this project aims to create a non-intrusive, non-wearable solution through the use...

Insight into trading limits in financial algorithms

In this project we aimed to create a post-trading day safeguard system that allows for the identification of bugs in the primary and secondary risk control systems at Optiver. These systems are needed to prevent undesirable exposure to the market from happening, and to ensure that they know exactly what this exposure is. The amount of input data...

Optimisation of Propellant Consumption for Power Limited Rockets: What Role do Power Limited Rockets have in Future Spaceflight Missions?

In this thesis we look at the most cost-<br/>effective trajectory for power limited rockets, i.e. the trajectory which costs the least amount of propellant. First some background information as well as the differences between thrust limited and power limited rockets will be discussed. Then the optimal trajectory for thrust limited rockets, the...

Shortest Path Optimisation of the CyberKnife treatment in Radiotherapy

In the history of medicine, different treatments for cancer have been developed, such as radiotherapy, surgery and chemotherapy. However, nowadays more than 50% of the people diagnosed with cancer, undergo a radiotherapy treatment. One of the devices used for the treatment is the CyberKnife: a robotic radiodurgery system that can move around the...

Ranking items: Is solving a seriation problem a good alternative for existing methods?

In this dissertation we look at the seriation problem and the applications of this problem. Given a set of items, we try to find an ordering based on the similarity between the items. We start by explaining the mathematical theory behind the seriation problem. Then we describe a couple of different methods that can be used to find a solution for...
