Schweidtmann, A.M. (author), Zhang, Dongda (author), von Stosch, Moritz (author)The term hybrid modeling refers to the combination of parametric models (typically derived from knowledge about the system) and nonparametric models (typically deduced from data). Despite more than 20 years of research, over 150 scientific publications (Agharafeie et al., 2023), and some recent industrial applications on this topic, the...review 2024

Kalikatzarakis, Miltiadis (author), Coraddu, A. (author), Atlar, Mehmet (author), Gaggero, Stefano (author), Tani, Giorgio (author), Oneto, Luca (author)For propeller-driven vessels, cavitation is the most dominant noise source producing both structure-borne and radiated noise impacting wildlife, passenger comfort, and underwater warfare. Physically plausible and accurate predictions of the underwater radiated noise at design stage, i.e., for previously untested geometries and operating...journal article 2023

Hendrickx, G.G. (author), Antolínez, José A. Á. (author), Herman, P.M.J. (author)In recent years, coastal management has been facing new challenges: socio-economic growth and consequent climate change impose new boundary conditions pushing coastal systems towards unseen states. For adaptation and mitigation strategies as well as risk management, the resilience of systems to these projected changes must be tested and...journal article 2023

Slinger, J (author)The development of the bilateral Long Term Vision for the Scheldt Estuary between 1999 and 2001 reveals that it is possible to move from a history of conflict to cooperation in just two years. A retrospective, insider perspective is used to analyse the integrated three-layer hybrid modelling at the heart of this groundbreaking agreement. We...journal article 2023

Kakolaki, Seyed Ebrahim Hosseini (author), Hakimian, Vahid (author), Sadeh, Javad (author), Rakhshani, E. (author)The sudden outage of a transformer due to a fault can cause irreparable damage to the electricity industry. Hence, by conducting momentarily inspections of the transformer's condition, faults can be promptly detected, and the transformer can be disconnected from the power grid to prevent subsequent failures in this equipment. Detecting faults...journal article 2023

Cademartori, Giulia (author), Oneto, Luca (author), Valdenazzi, Federica (author), Coraddu, A. (author), Gambino, Andrea (author), Anguita, Davide (author)The prediction of ship motions and quiescent periods, is of paramount importance for the maritime industry. The capability to predict these events sufficiently in advance has the potential to improve the safety and efficiency of several marine operations, such as landing and take-off on aircraft carriers, transfer of cargo, and mating...review 2023

Krabbenborg, Britt (author)Banks such as Rabobank depend on multi-year mortgage prepayment forecasts in order to make provisions for the associated prepayment risks. The econometric models they use are fitted to historical data, and as a consequence their models are fitted to a decreasing interest rate regime. Given the current economic climate of increasing interest...master thesis 2022

de Mol, Dennis (author)Accurate and robust vehicle state estimation is important for proper operation of vehicle control systems. For lateral stability control accurate estimation of the Vehicle Sideslip Angle (VSA) is of utmost importance. This thesis aims to develop an accurate and highly robust model to estimate the VSA. Common vehicle sensors such as the Inertial...master thesis 2022

Valchev, Iliya (author), Coraddu, A. (author), Kalikatzarakis, Miltiadis (author), Geertsma, R.D. (author), Oneto, Luca (author)Monitoring and evaluating the biofouling state and its effects on the vessel's hull and propeller performance is a crucial problem that attracts the attention of both academy and industry. Effective and reliable tools to address this would allow a timely cleaning procedure able to trade off costs, efficiency, and environmental impacts. In...review 2022

Kopbayev, Alibek (author), Khan, Faisal (author), Yang, M. (author), Halim, S. Zohra (author)The increased complexity of digitalized process systems requires advanced tools to detect and diagnose faults early to maintain safe operations. This study proposed a hybrid model that consists of Kernel Principal Component Analysis (kPCA) and DNNs that can be applied to detect and diagnose faults in various processes. The complex data is...journal article 2022

Cao, Zhi (author), Huang, Yunkai (author), Guo, Baocheng (author), Peng, Fei (author), Dong, J. (author), Hemeida, Ahmed (author)To facilitate the active magnetic bearing (AMB) design and analysis, an accurate and fast model that considers both rotor eccentricity and the saturation effect is necessary. In this article, a novel hybrid analytical model (HAM) for effective calculation of the magnetic field of the AMB is proposed. Eccentricity and local saturation are...journal article 2022

Hulskamp, Romy (author)The coastal area provides important services such as valuable habitats for wildlife, resources for regional development, and buffer zones for the land against natural disasters such as storm surges. But these narrow coastal areas experience pressure from both land and ocean side. In order to regulate sustainable coastal development, protect...master thesis 2021

Zhang, Le (author)Estuarine intertidal flats comprise valuable ecosystems and act as an important sediment source for the adjacent salt marsh systems. However, accelerating sea-level rise threatens the mudflats and associated ecosystems, where the mudflat accretion lag behind sea level rise. A reliable forecast on the morphological developments of the mudflat...master thesis 2021

Bakker, Michael (author)Design decisions which are made in the preliminary ship design phase have a significant influence on the performance and total cost of a ship. These design decisions are mostly made with very little knowledge of the ship design problem. In fact, it is the personal experience of the naval architect which plays a significant role in this phase of...master thesis 2021

(author)Fast diesel engine models for real-time prediction in dynamic conditions are required to predict engine performance parameters, to identify emerging failures early on and to establish trends in performance reduction. In order to address these issues, two main alternatives exist: one is to exploit the physical knowledge of the problem, the...journal article 2021

van Lange, Dion (author)This thesis captures the calibration of a FX hybrid model: The FX Black-Scholes Hull-White model. The main focus is on the calibration of the parameters in the Hull-White process: The mean reversion and the volatility parameter. The latter is commonly calibrated as a time-dependent parameter, whilst the mean reversion parameter is not. This...master thesis 2020

Schaaphok, Marianne (author)Burn injuries occur daily and can have severe physical and mental effects both in short and long term, such as disabilities due to severe skin contraction. Even though the mortality rate has decreased over the years, the need for a higher quality of life after severe burns remains. Decreasing the probability of a severe contraction is essential...master thesis 2020

Manley, D.J. (author), van Ham, M. (author), Hedman, L.K. (author)Understanding how inequalities are transmitted through generations and restrict upward spatial mobility has long been a concern of geographic research. Previous research has identified that the neighborhood in which someone grows up is highly predictive of the type of neighborhood he or she will live in as an independent adult. What remains...journal article 2020
