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 ... -
Local loss coefficients inside air cavity of ventilated pitched roofs
(Journal article; Peer reviewed, 2018)Pitched roofs with a ventilated air cavity to avoid snow melt and ensure dry conditions beneath the roofing are a widely used construction in northern parts of Europe and America. The purpose of this study has been to ... -
Local mechanical properties and precipitation inhomogeneity in large-grained Al–Mg–Si alloy
(Peer reviewed; Journal article, 2022)Al–Mg–Si (6xxx series) alloys show excellent mechanical properties due to the precipitates formed during heat treatment. However, heat treatment of these alloys results in a soft precipitation free zone (PFZ) close to grain ... -
Local Ocean Wave Field Estimation Using A Deep Generative Model of Wave Buoys
(Journal article, 2023)Estimating oceanic wave fields from sparse observations has been a long-standing challenge in oceanography and an important environmental metric desired for maritime operations. The requirement for frequent real-time updates ... -
Local soil classification and assessment of the mechanical properties with emphasis on pile adfreeze bond strength in Longyearbyen, Svalbard
(Master thesis, 2022)Construction engineering practices have been a highly sensitive topic regarding the Arctic infrastructure. The limitations of the permafrost behavior impose an analysis from the thermal and mechanical point of view. The ... -
Local strain energy based fatigue assessment of cruciform welded joints: experimental data analysis and influence of hot-dip galvanization
(Journal article; Peer reviewed, 2018)Performing the fatigue assessment of a welded joint using the Notch Stress Intensity Factors [1] presents two major challenges. The first is the necessity of a precise reconstruction of the stress field around the notch ... -
Local strain energy density for the fatigue assessment of hot dip galvanized welded joints: Some recent outcomes
(Journal article; Peer reviewed, 2017)Since in literature only data about the effect of the hot-dip galvanizing coating on fatigue behavior of unnotched specimens are available, whereas very few for notched components and none for welded joints, the aim of ... -
Local strain energy density for the fracture assessment of polyurethane specimens weakened by notches of different shape
(Journal article; Peer reviewed, 2017)Recent studies on local stress fields in proximity of crack and notch tips have shown that Strain Energy Density (SED), averaged in a circular control volume surrounding the point of stress singularities, represents a ... -
Local strain energy density to assess the multiaxial fatigue strength of titanium alloys
(Peer reviewed; Journal article, 2016)The present paper investigates the multiaxial fatigue strength of sharp V-notched components made of titanium grade 5 alloy (Ti-6Al-4V). Axisymmetric notched specimens have been tested under combined tension and torsion ... -
Local Structural Analysis of a Semi-Submersible Exposed to Ice Loads
(Master thesis, 2015)The subject of deep sea drilling in the Arctic is now more relevant than ever. The environment in Arctic offshore areas can be extremely harsh and the structures operating there will have to be designed accordingly. In ... -
Local thermodynamic description of isothermal single-phase flow in porous media
(Journal article; Peer reviewed, 2022)Darcy's law for porous media transport is given a new local thermodynamic basis in terms of the grand potential of confined fluids. The local effective pressure gradient is determined using non-equilibrium molecular dynamics, ... -
Localisation of Submarine Power Cables by Magnetometers on REMUS 100 AUV
(Master thesis, 2017)Power cables that are exposed to the marine environment are prone to damage, especially if they are located close to, or above, the seabed. Underwater surveys are carried out to ensure that cables are buried and inspect ... -
Localized corrosion damage prediction of steel plates in marine applications using quadrilateral inverse-shell elements based on iFEM
(Chapter, 2022)This research effort focuses on a damage detection strategy for identifying pitting corrosion locations in corroded marine structures using numerical approaches. To this end, a four-node quadrilateral inverse shell element ... -
Localized wrinkling of metal films on elastic and liquid substrates
(Peer reviewed; Journal article, 2019)Global and localized wrinkling phenomena in films/substrates have been widely studied by means of experiment and theoretical analyses in the past two decades. They have shown broad application prospect in microstructure ... -
Locomotion control of a biomimetic robotic fish based on closed loop sensory feedback CPG model
(Journal article; Peer reviewed, 2019)This paper presents mechatronic design and hierarchical locomotion control of a biomimetic robotic fish for three-dimensional swimming modes. Inspired by biological features of Lamprey, a closed loop sensory feedback Central ... -
Loftsutbygging ved bruk av prefabrikkerte takelementer - Utfordringer og fordeler sammenlignet med tradisjonell plassbygging, med utgangspunkt i Sannerkvartalet i Oslo.
(Bachelor thesis, 2022)Økt etterspørsel av boliger i storbyene gjør det relevant å utnytte allerede eksisterende bebyggelse. Spesielt i tettbebygde storbyer som Oslo må det gjøres tiltak for å følge den økte befolkningsveksten og urbaniseringen. ... -
Log Facies Evaluation and Property Modelling of a Turbidite Reservoir, the Gulf of Mexico
