Zhu, Man (author), Tian, Kang (author), Wen, Yuan Qiao (author), Cao, Ji Ning (author), Huang, L. (author)This study contributes to addressing the challenge of quickly obtaining an effective and accurate nonparametric model for describing ship maneuvering motion in three degrees of freedom (3-DOF). To achieve this, an intelligent ship dynamics nonparametric modeling method named improved PER-DDPG is proposed. This method leverages the deep...journal article 2023

Wang, Y. (author), Voskov, D.V. (author), Daniilidis, Alexandros (author), Khait, M. (author), Saeid, S. (author), Bruhn, D.F. (author)The efficient operation and management of a geothermal project can be largely affected by geological, physical, operational and economic uncertainties. Systematic uncertainty quantification (UQ) involving these parameters helps to determine the probability of the focused outputs, e.g., energy production, Net Present Value (NPV), etc. However,...journal article 2023

Li, H. (author), Lekić, A. (author), Li, Shan (author), Jiang, Dongrong (author), Guo, Qiang (author), Zhou, Lin (author)The distribution network (DN) reconfiguration is a well-known optimal power flow (OPF) problem. However, with the transition of DN from 'passive' to 'active', new technical challenges arise in DN reconfiguration. This article addresses two key issues in this regard. Firstly, the integration of local renewable generation (LRG) introduces...journal article 2023

Elmi, Zeinab (author), Li, Bokang (author), Liang, Benbu (author), Lau, Yui yip (author), Borowska-Stefańska, Marta (author), Wiśniewski, Szymon (author), Dulebenets, Maxim A. (author)Time management is crucial for liner shipping services. A variety of unexpected events can disrupt liner shipping schedules. A real-time port capacity analysis and rescheduling the original ship operations would be necessary to counteract the negative effects of such disruptions. Different ship schedule recovery options can be adopted in...journal article 2023

Daulat, Shamsuddin (author), Rokstad, Marius Møller (author), Bruaset, Stian (author), Langeveld, J.G. (author), Tscheikner-Gratl, F. (author)Small utilities often lack the required amount of data to train machine learning-based models to predict pipe failures, and hence are unable to harness the possibilities and predictive power of machine learning. This study evaluates the generalizability and transferability of a machine learning model to see if small utilities can benefit from...journal article 2023

Zhou, C. (author), van Nooijen, R.R.P. (author), Kolechkina, A.G. (author), Gargouri, E.F.G. (author), Slama, Fairouz (author), van de Giesen, N.C. (author)The dependency structure between hydrological variables is of critical importance to hydrological modelling and forecasting. When a copula capturing that dependence is fitted to a sample, information on the uncertainty of the fit is needed for subsequent hydrological calculations and reasoning. A new method is proposed to report inferential...journal article 2023

Xia, D. (author), Ma, Jihui (author), Sharif Azadeh, S. (author), Zhang, Wenyi (author)The collaborative design of the timetable and dynamic-capacity allocation plan of emerging modular vehicles (MVs) is a promising solution to the mismatch between supply and demand in public transportation studies; however, such efforts are subject to high-level dynamics and uncertainty inherent in operating environments. In this study, we...journal article 2023

Vasilikis, N. (author), Geertsma, R.D. (author), Coraddu, A. (author)Maritime industry has set ambitious goals to drastically reduce its greenhouse gas emissions through stipulating and enforcing a number of energy assessment measures. Unfortunately, measures like the EEDI, EEXI, SEEMP and CII do not account for the operational and environmental uncertainty of operations at sea, even though they do provide a...journal article 2023

Irnich, Jakob (author), van der Wal, C.N. (author), Duives, D.C. (author), Auping, Willem L. (author)Different leader-follower behaviors may be observed in models, such as group gathering, backtracking, and changing between groups. However, a comparison of these behaviors resulting in possible substantially different estimates of optimal evacuation procedures is lacking. Hence, we developed an agent-based model in combination with exploratory...conference paper 2023

(author), Kalnins, Kaspars (author)The Vibration Correlation Technique (VCT) is a non-destructive method to predict buckling loads for imperfection-sensitive structures. While successfully used to validate numerical models and predict experimental buckling loads, recommendations for defining the VCT experiment are scarce. Here, its sensitivity towards the number of load steps...journal article 2023

Crooijmans, Bastiaan (author)Climate agreement goals set by the Dutch government increase the urge to reduce our greenhouse gases. To fulfil these goals on a residential level a reduction of the emission of carbon which is produced during household demand and transportation (commute) is required. On a residential level, the amount of photovoltaic systems (PV) and electric...master thesis 2022

Neustroev, G. (author)Sequential decision-making under uncertainty is an important branch of artificial intelligence research with a plethora of real-life applications. In this thesis, we generalize two fundamental properties of the decision-making process. First, we show that the theory on planning methods for finite spaces can be extended to infinite but countable...doctoral thesis 2022

Almeida Pignatelli de Avillez, Miguel (author)Quasi-satellite orbits (QSOs) are orbits around the smaller primary in three-body systems. The MMX mission (developed by JAXA, to be launched in 2024) will use QSOs to orbit Phobos, before landing on its surface. This work studies the feasibility of using the invariant manifolds of three-dimensional QSOs for designing landing trajectories, using...master thesis 2022

Trommelen, Joost (author)Sea level variations and storm surges are expected to increase as a result of climate change. 570 cities and some 800 million people are by 2050 estimated to be exposed to these phenomena when emissions do not decrease (UCCRN, 2018). It is, however, deeply uncertain if and to what extent emissions will decrease. Additionally, the effects of...master thesis 2022

Matthieu, Mees (author)On-demand ridesharing might be an effective solution to reduce traffic congestion and, as a result, reduce emissions to mitigate environmental issues. However, travel times are more uncertain in ridesharing services compared to non-shared transit services due to their shared nature. For example, at one moment, the users are informed that the...master thesis 2022

Zhou, C. (author)Climate change is incompatible with the assumption of stationarity. This has lead to a sharp increase in the detection and study of nonstationarity in hydro-meteorological processes. Most hydro-meteorological processes are still analyzed by studying time series of observations. From the perspective of statistical characteristics, a stationary...doctoral thesis 2022
