de van der Schueren, Tom (author)The design space of power plants of naval surface vessels is ever expanding. As a result, the design space has become too large for a human design team to fully explore. Therefore, a concept exploration tool is introduced to generate and evaluate all possible concepts within the design space. An optimal solution is chosen based on ship...master thesis 2022

Gartland Bonet, Nico (author)The maritime industry has long relied on oils and heavy fuels as main energy carriers. The shipping sector still accounts for an important 2.5% of global greenhouse gas emissions. On top of this, current industry fuels contain high levels of sulfur and release nitrogen oxides upon combustion, which both can be extremely harmful to local...master thesis 2021

Arnoldus, Matthijs (author)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...bachelor thesis 2021

Azzahra Safira Suryanto, Azza (author)Urban Drainage Systems (UDS) are one of the most vital yet, complex infrastructures that support people's livelihood in urban areas. However, due to their mainly underground infrastructure and complexity, the planning and management of UDS are usually associated with high investment, which stakeholders sometimes overlook. As long-lived...master thesis 2021

Vos, Bas (author)One of the major challenges that the world currently faces is the energy transition. The aim of most countries worldwide is to reduce their carbon footprint, in order to slow climate change. Fossil fuel powered energy generation is replaced with an increasing share of variable renewable energy sources such as wind and solar energy. Because of...master thesis 2021

Bijvoets, Christian (author)Origami structures are found in mechanical technology more and more often. A less strict derivative of origami are Hinging Rigid Panel Structures, which are not bound to be developable from a single flat sheet of planar material. These Hinging Rigid Panel Structures can be applied to many fields of mechanical design, and moreover are interesting...master thesis 2021

Piña Rodriguez, Mariana (author)With the increasing need for more sustainable transportation, the electrification of IWW shipping becomes of great relevance. There are several ways to achieve this, from which the implementation of an exchangeable battery system is discussed in this research. Several challenges arise from the large-scale implementation of such a system. One of...master thesis 2021

Diercks, Ties (author)Optimising spacecraft reorientation manoeuvres with respect to time, energy and propellant is essential for achieving a high mission performance. Solving this reorientation problem in real time and onboard is considered to be a promising opportunity to achieve further efficiency improvements in space missions. However, the nonlinear programming ...master thesis 2021

Becetti, Belkassem (author)With the aim to reduce the CO2 emissions in the transportation sector, there have been significant developments in the recent few years where novel ground transport systems operating at airline speeds using all-electric propulsion have emerged to provide a sustainable alternative to classical methods of <br/>transport such as air travel. These...master thesis 2021

Prins, Reinier (author)The increase in quantity and electrification of energy in residential areas pushes the existing distribution network to its limits. If left unchanged, the network will suffer from voltage violations caused by the increase of electric vehicle (EV) charging, energy generation by Photovoltaics (PV) panels and the phasing out of natural gas....master thesis 2021

Athmer, Casper (author)The Train Unit Shunting and Servicing (TUSS) problem is an NP-hard problem encountered by the Dutch railway operator, Nederlandse Spoorwegen (NS). It considers trains at a shunting yard when they are not transporting passengers. It consists of four subproblems, involving assigning the trains at the yard to a transporting timetable (Matching),...master thesis 2021

Dijksman, Calvin (author)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...bachelor thesis 2021

Termote, Judith (author)Marine contractors as Heerema Marine Contractors (HMC) have made decommissioning part of their core business. Being the owner of two of the largest semi-submersible crane vessels (SSCVs), the choice for single lift jacket removal is straightforward. However, jackets in the Northern North Sea have a weight and height exceeding the crane capacity...master thesis 2021

Andringa, Sytze (author)Enterprise Modelling (EM) is the process of producing models, which in turn can be used to support understanding, analysis, (re)design, reasoning, control and learning about various aspects of an enterprise. Various EM techniques and languages exist, and are often supported by computational tools, in particular simulation. The goal of this...master thesis 2021

Vlasblom, Joris (author)This research evaluates and optimises the competitiveness of a combined wind, solar, and electrolyser plant in the Dutch electricity and hydrogen market. For the electricity market, this study used the EPEX spot market, where most electricity is traded. The hydrogen market is far less transparent than the electricity market; hence, a market had...master thesis 2021

Meeuwissen, Bart (author)Re-entry mission design remains an active field of study to safely return space missions back to Earth. With the developments in on-board computers, mission design and especially optimization of these missions has been performed numerically at an increasing rate at the cost of computing power. Analytical second-order methods have previously been...master thesis 2021

Church, Matt (author)The isostatic slab was developed by Pier Nervi and his colleague Aldo Arcangeli to create an elegant and easy to produce floor system, with efficient use of material. These slabs are designed with ribs aligned to the principal bending stress lines that support a flat deck. Concrete isostatic slabs are no longer constructed due to their expensive...master thesis 2021
