Understanding the dynamics of recent Norwegian extreme weather events and their influence on energy production
(Master thesis, 2021-08-05)The growing frequency and severity of extreme weather events in the Northern Hemisphere has prompted a lot of research being done on their origin and physical mechanisms. Both simplified and complex approaches have been ... -
Ignition of high-pressure hydrogen releases – Experimental study of impinging and non-impinging releases through a fast-acting valve, with and without a burst disc downstream of the valve
(Master thesis, 2021-09-14)A wide consensus of climate research indicates that anthropogenic greenhouse gas emissions affect the climate and causes the global mean temperature to rise compared to preindustrial levels. International treaties such as ... -
State of the Art Review of High Voltage Insulation Monitoring
(Master thesis, 2021-11-22)The devastating effects of global warming and climate change are now well understood and there is broad unity that fundamental changes are needed. This is clearly addressed in the United Nations Sustainable Development ... -
Modification and Analysis of a Multimegawatt Floating Spar Wind Turbine
