Model Uncertainty Analysis in Operational Risk Analysis
(Master thesis, 2016)A model is a simplified representation of the real world. Model uncertainty is a common issue in predictive models, and discussions on this can be found in many subjects. Model uncertainty is a branch of uncertainty analysis ... -
Model-Based and Model-Free Optimal Control of a Gas Liquid Cylindrical Cyclone
(Journal article; Peer reviewed, 2018)Optimal control is important in the oil and gas industry, where small changes of process variables may have significant economical, environmental and safety impacts. Finding the optimal setpoint for a controlled variable ... -
Model-based maintenance optimization
(Master thesis, 2021)The thesis aims to apply a model-based assessment for the different maintenance policies possible for a system and thereby aid the engineers in choosing the optimal maintenance policy. For this purpose, a system of separators ... -
Model-based Sustainability Assessment - An Enabler for Transition to Sustainable Manufacturing
(Journal article; Peer reviewed, 2016)The “sustainable manufacturing” concept has been discussed by researchers and manufacturers for decades. Still, a transition to sustainable manufacturing is limited due to constraints such as the lack of a practical ... -
Modelica Component Models for Non-diffracting Floating Objects and Quasi-static Catenary Moorings
(Chapter, 2020)In this paper, the theory behind determining the hydrodynamic response of a floating object in the presence of waves is discussed, followed by a simplification for the case of wave-transparent objects. The Morison equation ... -
Modelica Component Models for Oceanic Surface Waves and Depth Varying Current
(Chapter, 2020)In this paper, the theory of progressive ocean-surface gravity-waves is discussed, followed by the concept of the representation of the irregular sea-state by a sea spectrum. Fourier series decomposition of the irregular ... -
Modeling and Control of a Bifilar Crane Payload
(Journal article; Peer reviewed, 2018)This paper presents a modeling technique and a controller for an underactuated crane payload. The crane payload is modeled as a bifilar pendulum. The payload is attached to a sheave block, such that a cable can freely run ... -
