3. 2. A GIS-based landscape analysis of dissolved organic carbon in boreal headwater streams

   Författare :Jan-Olov Andersson; Lars Nyberg; Hjalmar Laudon; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boreal forests; wetlands; vegetation types; headwater streams; catchment hydrology; streamwater chemistry; DOC; GIS; terrain analysis; DEM; slope; wetness index; TWI; Freshwater ecology; Limnisk ekologi; Biology; Biologi;

   Sammanfattning : In boreal catchments, stream water chemistry is influenced and controlled by several landscape factors. The influence of spatially distributed variables is in turn dependent on the hydrological scale. LÄS MER

4. 3. On Invertibility of the Radon Transform and Compressive Sensing

   Författare :Joel Andersson; Jan-Olov Strömberg; Mikko Salo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radon transform; invertibility; compressive sensing; stability estimates; Mathematics; Matematik;

   Sammanfattning : This thesis contains three articles. The first two concern inversion andlocal injectivity of the weighted Radon transform in the plane. The thirdpaper concerns two of the key results from compressive sensing.In Paper A we prove an identity involving three singular double integrals. LÄS MER
