Oljevernberedskap ved oljeomlasting i Finnmark.
(Bachelor thesis, 2016)
Hovedoppgaven tar for seg spørsmål som hvordan foregår en STS-oljeomlasting? Hvordan opprettholdes beredskapen i et subarktisk område?
CCAD: A Basic Sample Database for Modeling Common Color Appearance
(Master thesis, 2016-08-30)
The consistency assessment of a set of cross-media color reproductions is an urgent research topic in color application field. This is enhanced by the various gamut devices which make it impossible to match exactly using ...
Supervisory Control of Line Breakage for Thruster-Assisted Position Mooring System
(Chapter; Conference object; Peer reviewed, 2015)
Thruster-assisted position mooring (TAPM) is an energy-efficient and reliable stationkeeping method for deep water structures. Mooring line breakage can significantly influence the control system, and ultimately reduce ...
A Tension-based Position Estimation Approach for Moored Marine Vessels
(10th IFAC Conference on Manoeuvring and Control of Marine Craft;MCMC 2015, Conference object; Journal article; Peer reviewed, 2015)
This paper presents a novel idea on a tension-based localization approach as a redundancy measure to handle the situation when the position reference (posref) signals are not available or significant GNSS drifts occur, ...
Modeling low emission scenarios for the European power sector
(Doctoral thesis at NTNU;2016:198, Doctoral thesis, 2016)
The long-term ambition for the European power sector is to almost completely decarbonize generation of electricity. There are potentially many ways of achieving this, however, assessing an optimal transition to a low-carbon ...
Stability Analysis Methods and Tools for Power Electronics- Based DC Distribution Systems, Applicable to On-Board Electric Power Systems and Smart Microgrids
(Doctoral thesis at NTNU;2016:271, Doctoral thesis, 2016)
The recent advancements in power electronics have resulted in widespread use of electronically controlled energy sources and loads in both AC and DC distribution systems. Power electronics also plays an important role in ...
Cement grouting during installation of ground anchors in non-cohesive soils
(Doctoral theses at NTNU, 2015:51, Doctoral thesis, 2015)
Pressure grouting during installation of grouted ground anchors is known to increase anchor capacity in non-cohesive soils, but little information is available on correlations between applied grouting pressures, duration ...
Identification of spatially distributed precipitation-runoff response routines for hourly simulation in gauged and ungauged basins
(Doctoral thesis at NTNU;2015:6, Doctoral thesis, 2015)
Due to sudden and considerable flow fluctuations during hydropeaking operation, forecasting of inflow to hydropower reservoirs at high temporal resolution (e.g. hourly) is required. Prediction of streamflow for both ...
Experiments on the droplet field in multiphase pipe flow
(Doctoral thesis at NTNU;2015:71, Doctoral thesis, 2015)
Gas-liquid flows are very common in industrial applications and many times involve three phases. Experiments are important as basis for development of 1D flow models used for design of multiphase transport systems. The ...
Low-Power Circuit Designs for In-Probe Ultrasound Imaging Applications
(Doctoral thesis at NTNU;2015:213, Doctoral thesis, 2015)
The main motivation behind the work in this thesis is to develop analog modules suitable for in-probe ultrasound imaging applications. The area and power are the main concerns for these applications given the limited area ...
