1. When Flying is Inevitable : How international companies and business travelers can contribute to the transformation towards a future of sustainable aviation
Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)Sammanfattning : This thesis emerged from a question that had been repeating itself in my head for a long period of time: If myself and the rest of the world face the fact that we are likely to keep flying for years to come for reasons somehow considered valid, how can we at the same time still contribute efficiently to achieving a more sustainable future of aviation? Based on this dilemma and focusing on the factor of impact, an actor with the power of creating a larger impact than a single individual was firstly identified. This actor also provides the perspective used in this thesis. LÄS MER
2. Jetbrandtester och vätgas : En litteratur- och intervjustudie om försök med vätgasjetflammor
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Vätgas är en energibärare som kan vara en av pusselbitarna i omställningen till en mer klimatneutral värld. Infrastrukturen byggs ut, industrin växer och vätgasfordon blir vanligare. LÄS MER
3. Hydrogen Pipeline Infrastructure Design for Germany in 2045
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Germany’s commitment to carbon neutrality by 2045 underscores the need for climate action, with hydrogen’s multiple uses in industry, transport, and energy offering a viable solution. Efficient retrofitting of the extensive natural gas pipeline network can enable hydrogen to be transported from supply to demand centers. LÄS MER
4. Warm dark matter simulations and 21cm astronomy
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : The recent boom in 21cm astronomy has piqued the interest of many, especially cosmologists realizing its applications in their field. This study aims to determine if 21cm astronomy is a good tool for testing the validity of keV WDM models, as well as creating a code capable of simulating keV WDM models from an existing CDM code.

5. Ion and ENA precipitation onto the upper atmosphere of Venus : Estimate of precipitation maps using data from a hybrid model
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Venus does not have a strong intrinsic magnetic field as the Earth, and its magnetosphere is induced by the interaction of the solar wind with the ionosphere. The near-Venus space environment is characterized by the presence of a bow shock and of an induced magnetic boundary linked to the interplanetary magnetic field orientation. LÄS MER
