3. 22. Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

   Författare :Ebba Söderström; Emanuel Bengtsson; [2022]
   Nyckelord :Electric road systems; Elonroad; life cycle assessment; rail; feed-in station; pick-up; on-board charger; climate impact; global warming potential; articulated lorry; lower medium car; bus; Technology and Engineering;

   Sammanfattning : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.

4. 23. Electric propulsion of satellites as an alternative for implementation of a sunshade system

   Kandidat-uppsats, KTH/Fysik

   Författare :Maheen Arfan; Isabelle Bonnier; [2022]
   Nyckelord :Geoengineering; Sunshade system; Electric propulsion; Orbital mechanics; Sub-lagrange;

   Sammanfattning : As an alternative solution to global warming, this thesis explores the possibility of aspace-based geoengineering scheme that may prove worthwhile to implement in parallel toother environmental efforts that help mitigate impact of climate change. One suggestionof a geoengineering solution is deploying a large number of sunshades in the vicinity ofthe first Lagrange point of the Sun-Earth system, and this prospective sunshade projectwould serve to shield Earth from incident solar radiation.

5. 24. Mission Design Considerations of the Propulsion System Demonstration as part of the Hugin Space Exploration Technology Satellite Mission

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Barkarmo Romil; [2022]
   Nyckelord :Electric propulsion system; Field Emission Electric Propulsion; Ion propulsion orbital maneuvers;

   Sammanfattning : Beyond Atlas is a Swedish private company with the goal of exploring the solar system with cheap and reliable spacecraft. Part of their maiden mission, Hugin, aims to demonstrate navigation, propulsion, and communication technology on a 3U CubeSat. LÄS MER

7. 25. Building A Fixed Wing Autonomous UAV

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Erik Barsby; Casper Augustsson Savinov; [2022]
   Nyckelord :fixed wing; bachelor thesis; KTH; Ardupilot; autopilot; electric propulsion; UAV; autonomous.;

   Sammanfattning : The goal of this bachelor thesis has been to evaluate and test the available open source software and commercial hardwarefor potential later use as the electrical system in the ALPHAUAV. ALPHA is a student project, with the goal of building an autonomous drone capable of high altitude, long-endurance missions to gather data from electromagnetic phenomena in the atmosphere. LÄS MER
