Modeling of Generic Offshore Vessel in Crane Operations With Focus on Strong Rigid Body Connections
(Journal article; Peer reviewed, 2016)Both marine surface vehicles and underwater vehicles are often equipped with cranes, robotic manipulators, or similar equipment. Much attention is given to modeling of both the dynamics of marine vehicles and the dynamics ... -
Modeling of material failure in foam-based components
(Journal article; Peer reviewed, 2004)The modeling of material failure in foam-filled beams was explored through numerical analyses with LS-DYNA. The study was based on previous physical tests on bending of square aluminum extrusions filled with aluminum foam. ... -
Modeling of MMC for Fast and Accurate Simulation of Electromagnetic Transients: A Review
(Journal article; Peer reviewed, 2017)Over the past decade, modular multilevel converters have evolved as the preferred choice for high voltage conversion systems. The design of the converter poses a computational challenge to the classical electromagnetic ... -
Modeling of Multiterminal HVDC Offshore Grids with Renewable Energy and Storage Integration by Opensource Tools
(Chapter, 2019)With increasing offshore wind penetration levels, more secure and flexible offshore electrical transmission systems are needed to ensure security of supply to onshore users. When considering long distances of electrical ... -
Modeling of nonlinear effects due to head-on beam-beam interactions
(Journal article; Peer reviewed, 2018)The beam-beam interaction is one of the most severe limitations on the performance of circular colliders, as it is an unavoidable strong nonlinear effect. As one aspires for greater luminosity in future colliders, one will ... -
Modeling of Offshore Crane and Marine Craft in Wave Motion
(Peer reviewed; Journal article, 2020)Safe handling of heavy payloads in an offshore environment requires careful planning and depends on the interaction between a crane and a vessel. This paper investigates the coupled dynamics between a multipurpose crane ... -
Modeling of oxidative MEA degradation
(Journal article; Peer reviewed, 2014)Considerable amount of work had been recently done researching the degradation of solvents for CO2 post combustion capture, especially for the benchmark solvent MEA. The degradation of the solvent can cause plant corrosion ... -

(Chapter, 2020)In order to describe and discuss the recrystallization behavior of commercial particle containing Al-alloys, the physical basis and a mathematical formulation of a softening model nicknamed ALSOFT, accounting for the ... -
Modeling of Remotely Operated Vehicle (ROV) Operations for Aquaculture
(Journal article, 2023)This paper proposes an extensive model for unmanned underwater vehicle operations in aquaculture and includes a dynamic 6 degrees of freedom (DOF) quaternion-based model of a remotely operated vehicle (ROV) and a model of ... -
Modeling of semi-competing risks by means of first passage times of a stochastic process
(Journal article; Peer reviewed, 2017)In semi-competing risks one considers a terminal event, such as death of a person, and a non-terminal event, such as disease recurrence. We present a model where the time to the terminal event is the first passage time to ... -
Modeling of surfactant adsorption on coated quartz crystal surfaces during surfactant flooding process
(Peer reviewed; Journal article, 2020)The focus of this study was the experimental determination of surfactant adsorption during low salinity water injection combined with surfactant flooding (LSW-SF) into an oil reservoir and development of an analytical model ... -
