1. 11. Hyperspectral and multispectral remote sensing for mapping grassland vegetation

   Författare :Thomas Möckel; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant diversity Partial least squares Ellenberg indicators Vegetation index Heterogeneity;

   Sammanfattning : As a consequence of agricultural intensification, large areas of species-rich grasslands have been lost and farmland biodiversity has declined. Previous studies have shown that the continuity of grazing management can have a significant influence on the environmental conditions and the levels of plant species diversity in grassland habitats.

3. 12. Mapping ultrastructural effects of proteotoxic stress on S. cerevisiae

   Författare :Katharina Keuenhof; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; yeast; heat shock; stress; electron microscopy; ultrastructure; nuclear envelope budding;

   Sammanfattning : Cells are the basic building blocks of any living being, whether the organism consists of only one, or many cells. The different cellular components interact with one another to maintain the viability of the cell. An essential element of cells are proteins – peptide chains folded into a specific conformation unique to every protein. LÄS MER

4. 13. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping

   Författare :Xin Niu; Yifang Ban; Paolo Gamba; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RADARSAT-2; spaceborne; polarimetric SAR; urban land cover; classification; Information technology; Informationsteknik;

   Sammanfattning : Urban represents one of the most dynamic areas in the global change context. To support rational policies for sustainable urban development, remote sensing technologies such as Synthetic Aperture Radar (SAR) enjoy increasing popularity for collecting up-to-date and reliable information such as urban land cover/land-use.

5. 14. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping

   Författare :Xin Niu; Yifang Ban; Laurent Ferro-Famil; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RADARSAT-2; Spaceborne; Polarimetric SAR; Urban Land cover; Object-based Rule-based Classification; Support Vector Machines; Contextual; Stochastic Expectation-Maximization; Markov Random Field.;

   Sammanfattning : Urban land cover mapping represents one of the most important remote sensing applications in the context of rapid global urbanization. In recent years, high resolution spaceborne Polarimetric Synthetic Aperture Radar (PolSAR) has been increasingly used for urban land cover/land-use mapping, since more information could be obtained in multiple polarizations and the collection of such data is less influenced by solar illumination and weather conditions.

7. 15. Paleoglaciology of Shaluli Shan, southeastern Tibetan Plateau

   Författare :Ping Fu; Arjen Stroeven; Lewis Owen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciology; Tibetan Plateau; geomorphological mapping; cosmogenic nuclide; Last Glacial Maximum; glacial erosion; basal thermal regime; paleoglaciologi; Tibetanska platån; geomorfologisk kartering; kosmogena isotoper; senaste glaciala maximat; glacial erosion; subglacial temperatur; Physical Geography; naturgeografi;

   Sammanfattning : Reconstructing the paleoglaciation of the Tibetan Plateau is critical to understanding linkages between regional climate changes and global climate changes. This work focuses on the paleoglaciology of the Shaluli Shan Mountain area in the southeastern Tibetan Plateau. LÄS MER
