6. 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
7. Elektrifiering av hydraulsystem : En studie kring lämpliga växlar och motorer för grävmaskinstillbehöret tiltrotatorn
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknikSammanfattning : Today’s electric excavators uses standard hydraulics to control external tools. To increase the degree of freedom the excavator is equipped with a tiltrotator placed between arm and bucket. LÄS MER
8. Reaction Wheel Control System for a Self-balancing Bike : Reaction wheel based control mechanism for a small scale prototype bike
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In this thesis, the design of a self balancing prototype bike with a reaction wheel as balancing mechanism will be investigated. Bikes are inherently unstable systems, that dynamically resemble an inverted pendulum at a stand still. LÄS MER
9. Mathematical Model for Inverter Power Output in PV Parks
Master-uppsats, Uppsala universitet/Institutionen för materialvetenskapSammanfattning : Solar photovoltaic (PV) parks have proliferated all over the world as a result of the growing demand for electricity, and especially electricity from renewables. As these parks become larger and complex, it becomes increasingly important to develop accurate and efficient mathematical models that can be used to predict their performance and optimize their design.

10. Possibility for Positive Energy Retrofit in Borlänge
Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : The built environment accounts for 40% of annual carbon dioxide (C02) emissions. Among the total emissions, building operations generate approximately 27% annually. Other than this, building materials, infrastructural materials, and construction (embodied carbon) contribute to an additional 13% annually [1]. LÄS MER
