Vendeloo, Bauke (author)This research considers Amels LE and SX super yachts. Bare hull, appended hull, and actuator disk simulations were performed using CFD, and compared to sea trial results. The results of the CFD are unique because they were generated after the sea trials were conducted, resulting in the ship speed in CFD and sea trial being similar. The results...master thesis 2021

Liang, F. (author)It is our choices that make us who we are. To lead a better life, we have to make better decisions. Nowadays, decisions are increasingly made in complex contexts, in a host of different application domains. Because of that, we need more reliable decision analysis methodologies to improve our decisions. The ability to deal with multi...doctoral thesis 2021

Smit, Jordi (author)Offline reinforcement learning, or learning from a fixed data set, is an attractive alternative to online reinforcement learning. Offline reinforcement learning promises to address the cost and safety implications of taking numerous random or bad actions online, which is a crucial aspect of traditional reinforcement learning that makes it...master thesis 2021

van Heijningen, Boudewijn (author)For the transportation of the produced energy at offshore windfarms to the onshore grid, export cables have to be installed in the sea bed. Usually, at first trenches are dredged, in which approximately one month later the cables are installed. During this period the trench should remain sufficiently open to install the cables, fulfilling the...master thesis 2021

Fenten, Jan (author), Bohm, N.L. (author), Van den Berg, Bas (author)The challenges we collectively face, such as climate change, are characterized by more complexity, interdependence, and dynamism than is common for educational practice. This presents a challenge for (university) education. These sustainability transition challenges are often described as wicked or VUCA (Volatile, Uncertain, Complex, and...conference paper 2021

van den Boomen, M. (author), Van der Meulen, Sjoerd (author), Van Ekris, Jonathan (author), Spanjers, Roel (author), Ten Voorde, Olle (author), Mulder, Janwin (author), Blommaart, Peter (author)<br/>The port of Rotterdam is the largest seaport in Europe. To maintain its position, the harbor will have to anticipate global transitions such as transferring to sustainable energy. Hydrogen is seen as a promising energy carrier; however, future demand is uncertain. The current research investigates decision making under uncertainty and...journal article 2021

Li, M. (author), Jiang, X. (author), Carroll, James (author), Negenborn, R.R. (author)The increasing capacity of offshore wind energy around the world brings challenges in Operation and Maintenance (O&M) management. Over the past years, many studies have focused on developing sound maintenance strategies in order to minimize maintenance cost or maximize availability. One of the promising maintenance strategies is...conference paper 2021

El Khelloufi, Zakaria (author)Energy transition goals to reduce carbon emissions are a driver key for an increase share of variable renewable energy sources (vRES). To achieve 49% of CO2 reduction by 2030 compared to 1990, the Netherlands set a plan to generate 84 TWh of electricity from renewable energy sources, where 35 TWh need to be generated exclusively from onshore...master thesis 2020

van den Boomen, M. (author)Ageing infrastructures and shortage of financing induce the need for optimising public infrastructure replacements. From an economic perspective, classical net present value comparison is traditionally the method of choice to decide on investments and replacements. The current research observes that typical infrastructure related features make...doctoral thesis 2020

Koster, Robert (author)The amount of air traffic worldwide is increasing, with an adverse effect on aircraft noise in the vicinity of airports as a result. Measurements and calculations have complementary benefits and limitations for the assessment of aircraft noise. A common method for the calculation of aircraft noise is ECAC Doc. 29. Various improvements of this...master thesis 2020

Shao, Fuwei (author)The problem that discussed is less an issue to the contexts, but a general critical reflection on the disciplinary of architecture. The determinant role of architects in design process and free interpretation of the inhabitants pose the conflictions. Our (architects) creativities and imaginations are confined within the given role and limited...master thesis 2019

Hagenaars, Kay (author)The information security (IS) risk assessment process is an essential part to organisation's their protection of digital assets. However, the fast changing IS environment causes for limited knowledge of eventualities, dependencies and values of systems and phenomena. Consequently, the IS risk assessment process is depending on the judgment of...master thesis 2019

Zhu, Y. (author), Goverde, R.M.P. (author)Unexpected disruptions occur frequently in railway systems, during which many train services cannot run as scheduled. This paper deals with timetable rescheduling during such disruptions, particularly in the case where all tracks between two stations are blocked for a few hours. In practice, the disruption length is uncertain, and a disruption...conference paper 2019

The site investigation (extent) and slope geometry, as well as the material properties and their spatial variability, are considered within a Bayesian network. The random finite element method ...conference paper 2019

van den Boomen, M. (author), Spaan, M.T.J. (author), Schoenmaker, R. (author), Wolfert, A.R.M. (author)Managerial flexibility in infrastructure investment and replacement decisions adds value. Real options analysis (ROA) captures this value under uncertain market prices. The concept of ROA is that future unfavourable payoffs can be deferred as soon as more information about market prices becomes available. The popularity of ROA is seen in a...journal article 2019
