Development of an Automated Bin Picking System for Cluttered Environments
Vadheim, Sondre Aleksander; Østerdal, Hans Bratland (Master thesis, 2018)The amount online purchases conducted by consumers show no sign of declining, and the growth in retail sales have rapidly increased over the last decade. This growth is driving the demand for automated packing and shipping ... -
Development of heart rate regulator system for exercise bikes
Hjertholm, Erik (Master thesis, 2018)Inactivity is considered to be pandemic and the societal costs are huge and rising. One highly efficient way of combating inactivity is by doing high intensity interval training. This however has shown to be a challenging ... -
Directional Wells in Shallow Reservoirs using Curved Conductors and Hammering - Concept and analysis of a novel installation method for curved conductors
Korvald, Lars Andreas; Schreiner, Jørgen Andre (Master thesis, 2015)One of the challenges encountered when planning wells in shallow reservoirs in the arctic is the development of a plan to drill a relief well. According to NORSOK such a plan is required to be in place prior to the initiation ... -
Droplet Erosion Protection Coatings for Offshore Wind Turbine Blades
Valaker, Emil Andre (Master thesis, 2015)Sintef har en visjon om å utvikle en egen patentert løsning for å redusere erosjon på vindturbinblader offshore. Dette prosjektet hadde som intensjon og støtte opp under utvikling av et bedre beskyttelsesbelegg og bistå ... -
Dynamic Compensation System for Landing Objects on a Moving Ship
Hansen, Jon Andreas; Dyrset, Eirik Husby (Master thesis, 2016)The focus of this thesis is directed towards the difficulties that may occur during a ship-to-ship load transfer operation at sea conditions. Today few ships have the ability to exchange motion-data about the motion dynamics, ... -
