Numerical study of wave transformation using the free surface reconstruction method
(Chapter, 2017)The study of irregular wave field is complex due to its random hydrodynamic characteristics. Many experimental studies have been performed in the past to study irregular waves. However, numerical investigations are less ... -
Numerical Study on Aerodynamic Damping of Floating Vertical Axis Wind Turbines
(Journal article; Peer reviewed, 2016)Harvesting offshore wind energy resources using floating vertical axis wind turbines (VAWTs) has attracted an increasing interest in recent years. Due to its potential impact on fatigue damage, the aerodynamic damping ... -
Numerical study on buckling of aluminum extruded panels considering welding effects
(Peer reviewed; Journal article, 2022)Aluminum extruded panels are increasingly used in marine structures as lightweight solutions. Less welding is needed for such extrusions than traditional built-up panels of welding stiffener to plate sheets. However, the ... -
A Numerical Study on Ductile Failure of Porous Ductile Solids With Rate-Dependent Matrix Behavior
(Peer reviewed; Journal article, 2020)This work examines the effects of loading rate on the plastic flow and ductile failure of porous solids exhibiting rate-dependent behavior relevant to many structural metals. Two different modeling approaches for ductile ... -
A numerical study on the combustion of a resolved carbon particle
(Journal article; Peer reviewed, 2021)Combustion of a single, resolved carbon particle is studied using a novel numerical approach that makes use of an overset grid. The model is implemented into the framework of a compressible Direct Numerical Simulation (DNS) ... -
Numerical study on the dynamic fracture behavior of 3D heterogeneous rocks using General Particle Dynamics
(Journal article; Peer reviewed, 2018)The General Particle Dynamics code (GPD) is developed to simulate initiation, propagation and coalescence of cracks in 3D brittle rock specimens subjected to dynamic loads. In GPD, fractures of particles are determined ... -
Numerical Study on the Dynamic Response of a Submerged Floating Tunnel Under Current Loads Based on the Segment Model Towing Test Results
(Chapter, 2020)Submerged floating tunnels (SFTs) are considered as one of the relevant concepts to replace ferry connection in the Norwegian Public Road Administration's plan to upgrade the E39 coastal highway. Current load including ... -
Numerical Study on the Effect of a Submerged Breakwater Seaward of an Existing Breakwater for Climate Change Adaption
(Chapter, 2018)In coastal areas, climate change is causing mean sea level rise and more frequent storm surge events. This means the breakwaters are expected to withstand the action of more severe incident waves and larger overtopping ... -
Numerical study on the effect of the Lüders plateau on the ductile crack growth resistance of SENT specimens
(Journal article, 2018)The increasing demand of energy prompts the petroleum industry exploitation activities to the Arctic region where the low temperature is a strong challenge, both for structural design and material selection. For structural ... -
Numerical study on the feasibility of offshore single blade installation by floating crane vessels
(Journal article; Peer reviewed, 2019)Compared with jack-up crane vessels that are now widely used in offshore wind turbine installation, floating crane vessels are more flexible with respect to working water depth and are much faster in relocation. They are ... -
Numerical study on the heading misalignment and current velocity reduction of a vessel-shaped offshore fish farm
(Peer reviewed; Journal article, 2019)Recently, the concept of a vessel-shaped fish farm was proposed for open sea applications. The fish farm comprises a vessel-shaped floater, five fish cages, and a single-point mooring system. Such a system weathervanes, ... -
Numerical study on the strain capacity of girth-welded X80 grade pipes
(Peer reviewed; Journal article, 2022)Strain capacity is an important performance indicator for designing and evaluating high-grade steel pipelines. Due to the inhomogeneity of material properties in welded structures, girth welds are one of the main factors ... -
Numerical study on the structural response of blast-loaded thin aluminium and steel plates
(Journal article; Peer reviewed, 2016)The inelastic response of thin aluminium and steel plates subjected to airblast loading is studied numerically and validated against experimental data. Special focus is placed on the influence of elastic effects and negative ... -
Numerical study towards closed fish farms in waves using two Harmonic Polynomial Cell methods
(Chapter, 2020)In order to avoid salmon lice and minimize environmental pollution, closed fish-farm concepts are gaining increasing attention in Norway. Violent sloshing of the water inside the closed cage then becomes an important issue ... -
Numerical viscosity in large time step hll-type schemes
(Journal article; Peer reviewed, 2018)We consider Large Time Step (LTS) methods, i.e., the explicit finite volume methods not limited by the Courant–Friedrichs–Lewy (CFL) condition. The original LTS method (LeVeque in SIAM J Numer Anal 22, 1985) was constructed ... -

Nurse entrepreneurs' ethical concerns: A qualitative inquiry of the pursuit of opportunity
(Peer reviewed; Journal article, 2022)Aim This study explores how nurse entrepreneurs' ethical concerns influence their pursuit of entrepreneurial opportunities. Background Nurse entrepreneurs break norms to challenge the status quo in health care, and ... -
Nurse rostering with fatigue modelling: Incorporating a validated sleep model with biological variations in nurse rostering
(Peer reviewed; Journal article, 2022)We use a real Nurse Rostering Problem and a validated model of human sleep to formulate the Nurse Rostering Problem with Fatigue. The fatigue modelling includes individual biologies, thus enabling personalised schedules ... -
