1. 1. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Tómas Halldórsson Alexander; [2023]
   Nyckelord :Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

   Sammanfattning : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

3. 2. Identification of shape errors in a parabolic solar collector : An improvement to the analysing algorithms examining the solar collector from optical measurements

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Malin Gelfgren; [2023]
   Nyckelord :;

   Sammanfattning : Increasing global warming with droughts, forest fires and melting polar ice has forced the world to speed up the transition from fossil fuel to fossil free energy. A big part of it is the use of solar energy. To obtain solar thermal energy, different sorts of solar collectors have been developed. LÄS MER

4. 3. Test and Calibration of CUBES: a CubeSat X-ray Detector

   Master-uppsats, KTH/Fysik

   Författare :Caroline Holmberg; [2022]
   Nyckelord :Applied Physics; Astroparticle Physics; Tillämpad fysik; Astropartikelfysik;

   Sammanfattning : CUBES is an X-ray detector that will be placed aboard the KTH 3U CubeSat mission, MIST. Its purpose is to detect high energy X-rays as well as to test various components in a space environment. Two CUBES will be placed on the satellite. Each CUBES consists of a printed circuit board (PCB) with three multi pixel photon counters (MPPCs). LÄS MER

5. 4. Determining the alignment of Solar Orbiter instruments STIX and EUI during solar flares

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Författare :Sofia Tynelius; [2022]
   Nyckelord :Solar flares; the Sun; STIX; EUI; alignment; pointing;

   Sammanfattning : Solar Orbiter is a mission launched in 2020 that will take images closer than ever of the Sun. It has ten instruments on board, including The Spectrometer/Telescope for Imaging X-rays (STIX) and The Extreme Ultraviolet Imager (EUI). LÄS MER

7. 5. Artificial Intelligence applications for railway signalling

   Master-uppsats, KTH/Transportplanering

   Författare :Benjamin Smakic; [2021]
   Nyckelord :Artificial Intelligence; AI; Machine Learning; ML; Computer Vision; railway signalling; ERTMS level 3; GPS; autonomous train operations; Artificiell Intelligens; Maskininlärning; datorseende; signalteknik; autonoma tåg; självkörande tåg.;

   Sammanfattning : The main purpose of this Master Thesis is to investigate how front-facing, train-mounted cameras and Computer Vision, a type of Artificial Intelligence (AI), can be used to compensate for GPS inaccuracies. By using footage from track-recording cameras, Computer Vision can be utilized to determine the number of tracks and the track occupancy of the train, which would compensate GPS inaccuracies in the lateral positioning.
