1. 6. "Hela världen på vår tröskel" : lokala reaktioner på en utlokaliserad flyktingförläggning

   Författare :Eva Wikström; Lennart Nygren; Gunnar Alsmark; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; refugee center asylum seekers; Swedish refugee policy; immigration policy; integration; reactions; localization; ambivalence; stigmatization; racialization; NIMBY; Social work; Socialt arbete;

   Sammanfattning : This thesis describes, conceptualizes and analyzes local reactions to the establishment of a refugee center in a small, remote mining community in Malmliden, rural Sweden, in the early 1990s. The purpose of the study was to explore and describe the local and wider contexts in which the reactions took place and to understand reactions in relation to these contexts. LÄS MER

3. 7. Multispectral Remote Sensing and Deep Learning for Wildfire Detection

   Författare :Xikun Hu; Yifang Ban; Ioannis Gitas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active fire detection; biome; multi-criteria; Sentinel-2; Landsat-8; burned area mapping; deep learning; semantic segmentation; machine learning.; aktiv branddetektering; biom; multikriterietillvägagångssätt; Sentinel-2; Landsat-8; kartläggning av bränt område; djupinlärning; semantisk segmentering; maskininlärningsmetoderna; Geoinformatik; Geoinformatics;

   Sammanfattning : Remote sensing data has great potential for wildfire detection and monitoring with enhanced spatial resolution and temporal coverage. Earth Observation satellites have been employed to systematically monitor fire activity over large regions in two ways: (i) to detect the location of actively burning spots (during the fire event), and (ii) to map the spatial extent of the burned scars (during or after the event).

4. 8. A Database of Microwave Single Scattering Properties of Ice Hydrometeors

   Författare :Robin Nils Ekelund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radar; ice hydrometeors; microwave; scattering properties; sub-millimetre; remote sensing;

   Sammanfattning : Microwave remote sensing by satellites is important for global observations of ice hydrometeors. Interpretation of the measurements requires sufficiently accurate knowledge of hydrometeors’ interaction with photons, i.e.  article scattering and absorption. LÄS MER

5. 9. Large-Scale Multi-Source Satellite Data for Wildfire Detection and Assessment Using Deep Learning

   Författare :Xikun Hu; Yifang Ban; Martin Wooster; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Wildfire; Remote Sensing; Active Fire Detection; Burned Area Mapping; Burn Severity Assessment; Sentinel-2; Landsat; Sentinel-1; Deep Learning; Semantic Segmentation; Image Translation; Skogsbrand; fjärranalys; aktiv branddetektering; kartläggning av bränt område; bedömning av brännskador; Sentinel-2; Landsat; Sentinel-1; djupinlärning; semantisk segmentering; bildöversättning.; Geoinformatik; Geoinformatics;

   Sammanfattning : Earth Observation (EO) satellites have great potential in wildfire detection and assessment at fine spatial, temporal, and spectral resolutions. For a long time, satellite data have been employed to systematically monitor wildfire dynamics and assess wildfire impacts, including (i) to detect the location of actively burning spots, (ii) to map the spatial extent of the burn scars, (iii) to assess the wildfire damage levels.

7. 10. Temporal Characteristics of Boreal Forest Radar Measurements

   Författare :Albert Monteith; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; antenna array; Synthetic aperture radar; temporal coherence; tomography; backscatter; remote sensing;

   Sammanfattning : Radar observations of forests are sensitive to seasonal changes, meteorological variables and variations in soil and tree water content. These phenomena cause temporal variations in radar measurements, limiting the accuracy of tree height and biomass estimates using radar data. LÄS MER
