1. Framing Russia in the National Security Strategy of the United States of America
Master-uppsats, Uppsala universitet/Institutet för Rysslands- och Eurasienstudier; Uppsala universitet/Institutionen för informatik och mediaSammanfattning : Historically, the USA and Russian Federation have been two world powers that used to compete for a dominant power position in the bipolar world and spread influence on less developed countries. Relationships between the USA and Russia have mostly been complex and tense,with several escalation periods during the Cold War. LÄS MER
2. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps
Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. LÄS MER
3. Alternative Energy Storage Solutions and Future Scenarios of the Austerland Energy System
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The project Austerland Energi at the eastern tip of the island of Gotland called Östergarnslandet was started as a response to the larger project Omställning Gotland funded by the Swedish government as an effort for a pilot project to convert to renewable energy to reach zero CO2-emissions for the country in 2045. The current plan for the Austerland energy system is a solar PV and wind production base with energy storage in the form of batteries and hydrogen which also can be used as vehicle fuel. LÄS MER
4. Miljöpartiet och kärnkraften – en analys över tid
Kandidat-uppsats, Umeå universitet/Statsvetenskapliga institutionenSammanfattning : This paper will examine how the Swedish green party, Miljöpartiet, has problematized the use of nuclear energy during the party’s first term of office 1988-1991 and compare that with how the party problematizes nuclear power during its current term of office, 2018-2022. I do this to examine the possible differences or similarities in the party’s critique of nuclear power between the different time periods. LÄS MER
5. Simulation of Transformer Inrush Currents and Their Impact on the Grid
Master-uppsats, Lunds universitet/Industriell elektroteknik och automationSammanfattning : This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E. LÄS MER
