Load Frequency-Based Power Management for Shipboard DC Hybrid Power Systems
(Peer reviewed; Journal article, 2020)The development of marine integrated power systems has enabled all-electric ship, with electric propulsion systems to be powered from diesel-generators. In addition, vessels with DC hybrid power sources such as fuel cell, ... -
Load measurements at riprap toe.
(Master thesis, 2018)Riprap is widely used as slope protection and when placed on the downstream slope of a rockfill dam, it provides erosion resistance under overflow conditions. For steep downstream slopes (S > 50%), initiation of riprap ... -
Load model for enhanced fatigue life estimation of Norwegian railway bridges: calibration, application, and uncertainties
(Doctoral theses at NTNU;2024:149, Doctoral thesis, 2024)The railway transportation is a crucial component of transportation infrastructure, known for its high capacity, environmental friendliness, and reliability. Despite requiring substantial initial investments, railway ... -
Load model of historic traffic for fatigue life estimation of Norwegian railway bridges
(Doctoral theses at NTNU;2019:73, Doctoral thesis, 2019)Material fatigue is the primary damage mechanism in steel railway bridges and ultimately causes material fracture and eventually component and system failure. It is essential that the infrastructure owner can predict and ... -
Load Modelling of Buildings in Mixed Energy Distribution Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:78, Doctoral thesis, 2007)The main topic of this thesis has been the development of a new method for load modelling of buildings in mixed energy distribution systems. The method estimates design load profiles, yearly load profiles, load duration ... -
Load transfer from coupled analysis to structural design of FWTs
(Master thesis, 2022)It is of research interest to establish a technique to capture the loads on the structural members of the offshore wind turbine when they are exposed to simultaneous wind and wave action. Unlike other floating offshore ... -
Loading and blade deflection of a tidal turbine in waves
(Journal article; Peer reviewed, 2019)A coupled numerical model has been developed and validated to study the fluid–structural interaction responses of a three-bladed tidal turbine in aligned waves and current. The unsteady blade element momentum (BEM) theory ... -
Loading rate effects on the fracture of Ni/Au nano-coated acrylic particles
(Journal article; Peer reviewed, 2012)Mechanical failure of monodisperse Ni/Au coated acrylic particles has been investigated by individual compression tests using nanoindentation-based technique equipped with a flat diamond punch. We have found that both ... -
Loads on the Gravity-net-cage from Waves and Currents
(Master thesis, 2014)Due to limited space close to shore and environmental concerns, the trend has become to move the fish farms to more exposed areas. This motivates the study of loads on the fish farm in more energetic currents and waves.In ... -
Local and Global Properties of the Harmonic Polynomial Cell Method: In-depth Analysis in Two Dimensions
(Journal article, 2017)A detailed and systematic analysis is performed on the local and global properties of the recently developed Harmonic Polynomial Cell (HPC) method, a very accurate and efficient field solver for problems governed by the ... -
Local and global responses of a floating bridge under ship-girder collisions
(Journal article; Peer reviewed, 2018)The Norwegian Public Roads Administration is running a project “Ferry Free Coastal Route E39” to replace existing ferry crossings by bridges across eight fjords in western Norway. Since most of the fjords are wide and deep, ... -
Local and non-local drivers of consumption-based water use in China during 2007–2015: Perspective of metacoupling
(Peer reviewed; Journal article, 2022)Increasingly growing consumption-based water use (WU) combined with climate change have exacerbated water stress globally and regionally, yet little is known about how the WU change is affected by metacoupled processes ... -

Local bracer vibrations for Offshore Wind jackets
(Master thesis, 2013)During the course of this master project, the candidates have worked with FEA of local vibrations occurring in bracers on offshore windturbine jacket. These vibrations arise as a dynamic response from wind-, wave-, and ... -
Local Dynamics of Offshore Wind Turbine Jacket Sub-structures
(Master thesis, 2010)The scope of this thesis has been to investigate the existence of out-of-plane vibration of jacket sub-structures for offshore wind turbines. This is done by making the program code JAC (Jacket Analysis Code), which is ... -
Local electrical properties of thermally grown oxide films formed on duplex stainless steel surfaces
(Journal article, 2018)The local electrical properties of thermally grown oxide films formed on ferrite and austenite surfaces of duplex stainless steel at different temperatures were investigated by Current sensing atomic force microscopy, X-ray ... -
Local entropy generation and entropy fluxes of a transient flame during head-on quenching towards solid and hydrogen-permeable porous walls
(Peer reviewed; Journal article, 2021)Premixed H2-air flames are studied in a one-dimensional wall-bounded configuration. The laminar flame propagates towards and quenches at a wall that is either solid or permeable. Entropy generation by each of 19 elementary ... -
Local Heating Networks with Waste Heat Utilization: Low or Medium Temperature Supply?
(Peer reviewed; Journal article, 2020)District heating enables an economical use of energy sources that would otherwise be wasted to cover the heating demands of buildings in urban areas. For efficient utilization of local waste heat and renewable heat sources, ... -
Local ionospheric modelling of GPS code and carrier phase observations
(Peer reviewed; Journal article, 2008)A limiting factor for successful ambiguity resolution in precise GPS positioning is the existence of un-modelled ionospheric errors in both the carrier phase and the pseudorange measurements. In this study, the ionospheric ... -
