1. 6. 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.

3. 7. 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.

4. 8. Med kant av guld och silver... : En studie av knypplade bårder och uddar av metall 1550-1640

   Författare :Lena Dahrén; Margareta Nockert; Maths Isacson; Johan Knutsson; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Bobbin lace; gold; silver; edgings; borders; ecclesiastic textiles; dress costume; portrait; Knyppling; guld; silver; liturgiska textilier; dräkt; porträtt; handel; Art; Konstvetenskap; Textile Studies; Textilvetenskap;

   Sammanfattning :  The study examines bobbin-made borders and edgings in gold and silver during the period 1550-1640. The aim of the thesis is to study the technique of bobbin made lace and to place it in a historical, social and economic context. LÄS MER

5. 9. Remote Sensing of Urbanization and Environmental Impacts

   Författare :Jan Haas; Yifang Ban; Costas Cartalis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remote Sensing; Urbanization; Land Use Land Cover LULC ; Environmental Impact; Landscape Metrics; Ecosystem Services; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : This thesis aims to establish analytical frameworks to map urban growth patterns with spaceborne remote sensing data and to evaluate environmental impacts through Landscape Metrics and Ecosystem Services. Urbanization patterns at regional scale were evaluated in China's largest urban agglomerations and at metropolitan scale in Shanghai, Stockholm and Beijing using medium resolution optical satellite data.

7. 10. Connecting Systemic RNAi to the Endomembrane System in Caenorhabditis elegans

   Författare :Benjamin T. Holmgren; Andrea Hinas; Gerhart Wagner; Peter Brodersen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemic RNAi; RNAi inheritance; Endomembrane system; Late endosome; SID-5; SEC-22; SYX-6; C12D8.1; RNA; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

   Sammanfattning : RNA interference (RNAi) is a gene regulation mechanism conserved among eukaryotes. To silence gene expression, RNAi relies on a short single-stranded guide RNA to steer the RNA-induced Silencing Complex (RISC) to mRNAs with guide strand-complementary sequences. RNAi is a highly membrane-associated process. LÄS MER
