1. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER
2. Constructing a Social Profitability Index: Socially Responsible Investing in Electric Utilities
C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomiSammanfattning : Building on a theory about the Social Profitability Index (SPI), this paper is the first to construct an SPI in practice ranking investment opportunities based on social and financial returns within the electric utility industry. The social return is the investor-preference weighted social gain from avoiding carbon emissions by changing to renewable production technology in a firm. LÄS MER
3. Electrical Discharge Interaction with Lithium-Ion Battery Vent Gases: Investigations using High-Speed Imaging and Breakdown Analysis
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : The increasing drive for sustainable and eco-friendly transportation has made the electrification of cars a top priority in the energy and transportation sectors. Ensuring the safety of electrical vehicle (EV) batteries is of the utmost importance. LÄS MER
4. Heat recovery from low emission steel production through electrolysis and hydrogen reduction
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : The steel industry is a large emitter of carbon dioxide and uses a lot of energy. Because of an increased awareness of the detrimental effects of climate change, research in alternative ways to operate steel plants have been made. It is now possible to build plants with far less emissions by using electrolysis and hydrogen reduction. LÄS MER
5. Feasibility Study of Resistivity Measurement of Metal Surfaces to Address Potential Dislocations Caused by Surface Conditioning
Master-uppsats, Uppsala universitet/FREIASammanfattning : High electrical fields are needed inside the accelerating cavities of particle accelerators in order to accelerate the particles to higher energies in shorter distances. But high electrical fields will lead to electrical breakdowns. LÄS MER
