A Dimensional-Decomposition Approach for Stochastic Scale-Resolving Simulations of Turbulent Reacting Flows
(Doctoral theses at NTNU;2018:399, Doctoral thesis, 2018)High-fidelity and reliable numerical design tools are main keys to the development of novel gas turbines for hydrogen-rich fuels. However, state-of-the-art simulation tools for the most part only give a bulk approximation ... -
A Discrete Element Method Study of Shear Localisation in Granular Material
(Master thesis, 2020)En fleksibel grensebetingelse er implementert for simulerte trykktester i diskret elementmetode (DEM) programmet Yade. DEM simulerer individuelle partikler i et granulært materiale. Med enkle kontaktlover og fysikk på ... -
A discrete-modules-based frequency domain hydroelasticity method for floating structures in inhomogeneous sea conditions
(Journal article; Peer reviewed, 2017)Based on the three-dimensional (3D) potential theory and finite element method (FEM), this paper proposes a new numerical method for hydroelastic predictions of floating structures in inhomogeneous seabed and wave field ... -
A discussion of continental lithospheric stretching models and comparison with interpreted 2D seismic data of the Viking Graben of the northern North Sea
(Master thesis, 2019)Riftmarginer markerer overgangen fra et kontinent til hav, og inneholder en oversikt over dets rifthistorie i arkitekturen. Ikke all rifter vil imidlertid utvikles til stadiet for skorpeseparering, men stanse før de når ... -
A discussion of risk influencing factors for maritime accidents based on investigation reports
(Chapter, 2017)This paper reports findings from a review of investigation reports from maritime accidents. Based on a systematic analysis of 95 reports, we discuss a selection of typical causes and circumstances for serious maritime ... -
A Discussion of Technical Challenges and Operational Limits for Towing Operations
(Master thesis, 2017)This thesis is written on the subject of marine towing operations. The purpose of the thesis is to identify and discuss technical challenges related to towing operations with respect to safety and operability. In addition, ... -
A displacement-free formulation for the Timoshenko beam problem and a corresponding isogeometric collocation approach
(Journal article; Peer reviewed, 2017)We present a reformulation of the classical Timoshenko beam problem, resulting in a single differential equation with the rotation as the only primal variable. We show that this formulation is equivalent to the standard ... -
A distributed anti-collision decision support formulation in multi-ship encounter situations under COLREGs
(Journal article; Peer reviewed, 2015)A multi-ship anti-collision decision support formulation is studied in a distributed and real time way. Under the general requirements from COLREGs rules and regulations, the performance of course alteration and changing ... -
A domain-decomposition strategy for a compressible multi-phase flow interacting with a structure
(Journal article, 2014)The problem of a high-pressure gas cavity and its interaction with surrounding liquid and a close-by structure is examined numerically. Even though this is of interest in many practical applications, here, the focus is on ... -
A dynamic analysis of in-situ stress state at the Upper Tamakoshi Hydroelectric Project area
(Journal article; Peer reviewed, 2018)The in-situ stress condition in the rock mass is influenced by both tectonic and geological environment such as faulting and shearing in the rock mass. This influence is of considerable magnitude in the Himalayan region ... -
A dynamic analysis of Skuteviksboder in Bergen and alternative load-bearingsystems
(Master thesis, 2010)A seismic analysis of Skuteviksboder is carried out by a simplified hand calculation in addition to a computation by the analytical program FEM-design. Alternative load-bearingsystems are discussed as well. The theory that ... -
A dynamic Bayesian network approach for prognosis computations on discrete state systems
(Journal article, 2017)The maintenance optimization of complex systems is a key question. One important objective is to be able to anticipate future maintenance actions required to optimize the logistic and future investments. That is why, over ... -
A Dynamic Channel Model for Indoor Wireless Signals: Working Around Interference Caused by Moving Human Bodies
(Journal article; Peer reviewed, 2018)The use of indoor wireless devices has substantially increased in recent years. This escalation is due to the expansion of traditional communication devices, such as mobile phones and laptop computers, to less traditional ... -
A dynamic river network method for the prediction of floods using a parsimonious rainfall-runoff model
(Journal article; Peer reviewed, 2019)Floods are one of the major climate-related hazards and cause causalities and substantial damage. Accurate and timely flood forecasting and design flood estimation are important to protect lives and property. The Distance ... -
A dynamic stress state analysis at the pressure tunnel of Upper Tamakoshi HPP, Nepal
(Chapter, 2018)In theory, in-situ stress state of an area of concern is mainly governed by gravity-induced stress, tectonic ac-tivity and topographic condition of that area. The tectonic and geological environment such as faulting and ... -
A family of hyperelastic models for human brain tissue
