11. FEASIBILITY ANALYSIS OF THE DRIVE TRAIN ELECTRIFICATION FOR A RESCUE BOAT
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Progressing constraints on green house gas emissions lead to a sustainability trend,which greatly a↵ects the transport sector. Nowadays, companies show increasing interest indeveloping sustainable solutions. LÄS MER
12. Användarcentrerad utvärdering samt utveckling av ett larmsystem för vattenjet-propulsor
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktionSammanfattning : The purpose of this master thesis is to investigate how alarm systems and their visualizations, as well as signals affect work situations and decision making processes aboard vessels with water jet propulsion. Furthermore, this study aims to identify important aspects of the perception of alarm systems and which aspects that are more or less affected by stress, lack of information as well as audible and visual signals.

13. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.

14. Rim-Jet - A Mechanical Design for a Shaft-less Propulsor
Master-uppsats, KTH/Maskinkonstruktion (Avd.)Sammanfattning : During sea rescue operations it is common for the rescue vessels to operate in water with high number of debris that can get stuck in the propulsor. In particular plastic ropes that can get tangled around the shaft and melt causing a complete stop or damage the motor. LÄS MER
15. Layout of spillway aerator air ventsand its effect on air supply
Master-uppsats, KTH/MekanikSammanfattning : Chute aerators are constructed to protect spillways from cavitation damage.They function by launching the water ow as a jet and supplying airunderneath since having air entrained into the water is an eective way tomitigate cavitation. LÄS MER
