1. Small scale VTOL aircraft using only one lift-producing motor : A study of lift capacity for a Vertical Take-Off and Landing capable aircraft
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The usage of unmanned aerial vehicles in applications such as terrain mapping and surveillance is proliferating in the modern world. This project aims to investigate the feasibility, in terms of payload capacity and stability, of small scale winged aircraft that have the ability to lift and land vertically, while also being able to transition to normal forward flight using wings for primary lift.

2. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. LÄS MER
3. Calibration of the Measurement System for Methane Pyrolysis in Rocket Nozzle Cooling Channels
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Methane-based rocket propellant is gaining traction as a green technology with advantages in sustainability, cost-effectiveness, and performance. However, under high temperatures found in rocket nozzle cooling channels, methane can undergo thermal decomposition known as methane pyrolysis, resulting in the generation of hydrogen and solid carbon.

4. Development of a Compact Drive System for Total Artificial Heart
Master-uppsats, KTH/Medicinteknik och hälsosystemSammanfattning : Over eight decades of research into total artificial hearts (TAHs) has significantly contributed to saving end-stage heart failure patients. However, at the current stage of development TAHs have several limitations, one of them being their bulkiness. LÄS MER
5. Misfire Detection in Heavy Duty Diesel Engines Using Knock Sensors
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : In this thesis the possibility of using knock sensors for misfire detection in heavy duty diesel engines is investigated. This is of great interest due to many emission legislations getting stricter, especially in the US where robust misfire detection is mandatory for these types of engines. LÄS MER
