16. SOLAR WIND HEATING OBSERVED BY SOLAR ORBITER
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : In this project, we investigate the plasma heating associated with coherent structures, such as current sheets and vortices, in different solar wind conditions: slow solar wind, stream interaction regions, and heliospheric current sheets, observed by the Solar Or- biter mission. To unravel this mystery, we first use the Partial Variance of Increment method [1] to locate these coherent structures. LÄS MER
17. Energikartläggning av mobilt batterilager i kombination med en högeffektsladdare och påverkan på det lokala elnätet
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/ElektricitetsläraSammanfattning : To achieve the established environmental goals, a significant transformation is requiredin the Swedish transport sector. This includes a shift away from fossil fuels and a greateremphasis on electrifying a larger portion of the vehicle fleet. LÄS MER
18. Vägval för Uppsala kommun : Ett utvecklat verktyg som kan beskriva och förutspå ett distrikts effektkonsumtion och dess effekttoppar
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : This report is based on the work carried out on behalf of Uppsala Municipality within the framework of the course Independent Work in Energy Systems.The main purpose of the project was to develop a tool capable of generatingreliable simulations of power demand in 24 areas for the future developmentof the Southeast District in Uppsala.

19. Model Development for Wave Energy Converter Arrays in the Frequency Domain
Master-uppsats, Uppsala universitet/Elektricitetslära; Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : In this thesis, a model has been developed to analyze the behavior of wave energy converter arrays in the frequency domain. This development serves the purpose of establishing an in-house model tool for array modelling for CorPower Ocean. LÄS MER
20. Interfacial Dynamics at Surface Modified Molecular/Perovskite Solar Cells : How measurements are made to understand solar cell stability
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Humanity has great energy demands, and must simultaneously combat climate change by curbing anthropogenic greenhouse gas emissions. Perovskite solar cells (PSC) provide a low-carbon energy source, at lower production costs than traditional silicon-based solar cells. PSC's suffer some issues with long-term stability. LÄS MER
