    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.

  3. 12. Geospatial data and knowledge on the Web : Knowledge-based geospatial data integration and visualisation with Semantic Web technologies

    Författare :Weiming Huang; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geospatial data integration; data visualisation; Semantic Web; Linked Data; ontology;

    Sammanfattning : Geospatial information is indispensable for various types of spatially informed analysis and decision-making, such as traffic analyses, and natural resource management. In addition, geospatial information is one of the most powerful information integrators to bridge diverse sources of information. LÄS MER

  4. 13. Fokus på föra : Om svenska funktionsverbsfrasers semantik och valens, med särskild utgångspunkt i verbet föra

    Författare :Renate Walder; Mats Thelander; Lena Ekberg; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Swedish language; functional verb structures; Swedish; cognitive semantics; polysemy; metaphor; domain-mapping; valency; corpus linguistics; Svenska; Swedish language; Svenska språket; nordiska språk; Scandinavian Languages;

    Sammanfattning : Functional verb structures, e.g. to have a break, to take into account, consist of a functional verb and an abstract noun (in a nominal phrase, NP, or a prepositional phrase, PP). The purpose of this thesis is to test whether three of the most central claims about these structures apply to Swedish functional verb structures with the verb föra. LÄS MER

  5. 14. Mapping the structure of science through clustering in citation networks : granularity, labeling and visualization

    Författare :Peter Sjögårde; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The science system is large, and millions of research publications are published each year. Within the field of scientometrics, the features and characteristics of this system are studied using quantitative methods. LÄS MER

  7. 15. Multi-Modal Deep Learning with Sentinel-1 and Sentinel-2 Data for Urban Mapping and Change Detection

    Sammanfattning : Driven by the rapid growth in population, urbanization is progressing at an unprecedented rate in many places around the world. Earth observation has become an invaluable tool to monitor urbanization on a global scale by either mapping the extent of cities or detecting newly constructed urban areas within and around cities.
