van Dijk, Casper (author)Parcel delivery companies offer time-guaranteed transportation of parcels, letters and packages, picked up at one customer and delivered at another. The time in which this has to be done depends on the service level that the customer pays for. To transport the parcels, a network is used consisting of facilities and links, where the facilities...master thesis 2018

de Zeeuw, Wessel (author)Even though negative effects on the use of crude oil have surfaced over the past years, our energy matrix still largely relies on this energy source. The production of oil, therefore, plays an important role in our society. Unfortunately, the process of oil production is highly uncertain. There are uncertainties associated on the production...master thesis 2018

Xavier, Donnatella Germaine (author)This Masters thesis is a new perspective on Large Eddy Simulation. The capability of goal oriented model constrained optimization technique to generate stable reduced order models without any additional stabilization term or subgrid scale modelling has been demonstrated. The low dimensional projection modes sought by the optimization program...master thesis 2018

van der Zee, Menno (author)Privately owned cars are an unsustainable mode of transportation, especially in cities. New Mobility on Demand (MoD) services should offer a convenient and sustainable alternative to privately owned cars. Notable in this field is the recent uprise of ride-sharing services such as offered by companies like Uber and Grab. Such services, especially...master thesis 2018

Perdeck, Matthias (author)In interplanetary space missions, it is convenient to have a second departure opportunity in case the first is missed. Two distinct approaches to minimizing the maximum of the two Delta-V budgets of such a trajectory pair, are developed. The first (‘a priori’) approach optimizes the variables of both trajectories at once. The second (‘a...master thesis 2018

Sfikas, Ilias (author)Raising environmental concerns have stimulated the development of renewable energy, including energy from the oceans, which contain a huge potential. In this thesis, particular emphasis is given to wave energy, which can deliver up to 2 TW on a global scale. The aim of this thesis is to optimize the control system of the Symphony Wave Power...master thesis 2018

de Bruijn, Dirk (author)European shipyards are building increasing amounts of complex ships such as off-shore, dredging or naval ships that are engineered-to-order. The block division is made when only preliminary hull structural design, functional compartments and the location of major equipment are known. The existing production scheduling optimization algorithms use...master thesis 2017

Vigney Kumar, Vigney (author)Offshore Wind Farm (OWF) installation procedure is a complicated phase requiring excellent management of resources for timely completion of tasks. The wind farm installation period involves crucial stages like streamlining onshore logistics, transportation of components on vessels, installation of foundations, wind turbines, and cable laying,...master thesis 2017

van Beurden, Merlijn (author)In my thesis, I have done research into the optimization of stopping patterns and frequencies of public transport services within a network. I have developed a model that takes both passenger and operator costs into account. The model has been run for a small fictional network and for the metro and train network of Amsterdam, to explore how the...master thesis 2017

Spillenaar Bilgen, Jesper (author)The main goal of any launch vehicle is to bring as much payload to space as possible. Space planes have been studied for decades, as they are thought to be more cost effective for frequent access to space than traditional expendable launchers. This research aims at optimizing the payload capacity of a single stage to orbit (SSTO) horizontal take...master thesis 2017

van der Planken, Jonathan (author)In this research the role of thick flexible soles in energy-efficient humanoid walking is analyzed. It is<br/>hypothesized that, the addition of underactuated degrees of freedom under the foot gives the robot<br/>the potential to execute a pseudo-passive walking motion 1, which yields a decrease in ankle torque<br/>and energy expenditure....master thesis 2017

Jonkman, Jake (author)Recently, the effects of quantization on the Primal-Dual Method of Multipliers were studied.<br/>In this thesis, we have used this method as an example to further investigate the effects of quantization on distributed optimization schemes in a much broader sense. Using monotone operator theory, the effect of quantization on all distributed...master thesis 2017

Wang, Weijun (author)The finite-element method can easily handle complicated geometries because of the application of unstructured meshes. Unlike the Cartesian grid used in the finite-difference method, the unstructured mesh can follow the sharp interfaces that separate two layers of different properties. Therefore, the finite-element method can provide more...master thesis 2017

Broxterman, Stefan (author)Topology optimization is a strong approach for generating optimal designs which cannot be obtained using conventional optimization methods. Improving structural characteristics by changing the internal topology of a design domain has been fascinating scientists and engineers for years. Topology optimization can be described as a distribution of...master thesis 2017

Földes, Gergely István (author)Airports are highly complex systems that can generate economic growth<br/>on their own. Accordingly, airports should take proactive actions to<br/>create a status quo between the stakeholders(the airport itself,<br/>airlines, passengers) in the tactical planning of the aircraft stand<br/>allocation. Namely, the harmonization between the...master thesis 2017

Verhoef, Nick (author)The structures which HMC installs offshore are fabricated onshore and subsequently moved onto a barge or ship, seafastened and then transported to the offshore location. The process of moving a structure from the onshore quayside to the barge or ship is called the load-out. This load-out can be performed by lifting, skidding or using a trailer ...master thesis 2017

Maljaars, J.L. (author)Over the years, the installed capacity of offshore wind turbines is increasing rapidly. However, the Levelized Costs Of Energy (LCOE) is still higher than the LCOE of traditional energy production methods like nuclear power or energy from coals or gas. This research focuses on a further decrease of the LCOE, by minimizing the mass of a monopile...master thesis 2017

ter Haar, O.A. (author)The increasing penetration of wind power generation introduces uncertainty in the behaviour of electric power grids. This work is concerned with the problem of day-ahead reserve scheduling (RS) for power systems with high levels of wind power penetration, and proposes a novel set-up that incorporates an alternating current (AC) Optimal Power...master thesis 2017

van der Meijden, S.A. (author)A minimization of disturbance caused by aircraft noise events and a reduction of fuel consumption during the initial and final phase of flight. These are the two objectives that play an important role in the Flexible Runway Allocation Model. By taking into account fuel consumption alongside noise annoyance, this model enables to analyze and...master thesis 2017

Carlier, M. (author)A high percentage of hospital admissions is due to surgical interventions. The operating theatre, which holds the operating rooms (ORs), is therefore one of the key resources in hospitals. Managing the operating theatre and finding an optimal OR schedule is complex due to the many factors that influence it. Scheduling a surgery in an OR...master thesis 2017
