A comparison between fully-unsteady and quasi-steady approach for the prediction of the propeller performance in waves: Prediction of the propeller performance in waves
(Peer reviewed; Journal article, 2020)Maritime transport is the most energy-effective mode to move large amounts of goods around the world. Hauling cargo via waterway produces an enormous quantity of greenhouse gas emissions. Vessel fuel efficiency directly ... -
Comparison between Measured and Calculated Riser Response
(Master thesis, 2012)Well intervention operations can inflict large strains on a wellhead. The seabed in the North Sea is very rigid up to the point where the sea water meets the mud or sand. This is one of the reasons why wellheads operating ... -
Comparison Between Microstructure Parameters and Electrochemical Performance of Ni-CGO Anodes in SOFC Subjected to Redox-Cycling
(Master thesis, 2011)The aim of this thesis was to create an understanding between the electrochemical performance of a porous Ni-CGO anode used in SOFC, and its microstructural parameters when subjected to redox-cycling. The anode samples ... -
Comparison between RDBMS and NoSQL for Aviation Data
(Master thesis, 2019)Kontekst: Databaser er essensielle i nesten alle programvareprodukter i dag. Ytelsen på databaser kan påvirke produktet i stor grad når det kommer til bruk. Det er derfor avgjørende at ytelsen er så god som det er mulig å ... -
Comparison between Si MOSFETs and GaN HEMTs with special emphasis on low load problems occuring in the LLC resonant converter
