  1. 1. Kroppar under träd – en miljö för konstnärlig forskning

    Författare :Henric Benesch; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Artistic Research; Architecture; Change; Doxa; Environment; Heuristics; Space; Poetics; Doxa;

    Sammanfattning : This dissertation in the field of artistic research is an articulation, in words and images, on the experience of working with a notional environment for artistic research. It is not a reflection on or a description of the process which the work has involved, but above all an articulation, characterisation and development, in words and images, of the conceptual and pictorial world constituted during, through and in the course of the actual work on an environment for artistic research in Vasaparken, Göteborg.

  3. 2. Remote Sensing of Woodland Structure and Composition in the Sudano-Sahelian zone : Application of WorldView-2 and Landsat 8

    Författare :Martin Karlson; Madelene Ostwald; Tina Schmid Neset; Heather Reese; Frédéric Achard Forobs; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Remote sensing; Sudano-Sahel; woodland; agroforestry; WorldView-2; Landsat 8; tree attributes; tree canopy cover; aboveground biomass; Random Forest; Fjärranalys; Sudano-Sahel; woodland; WorldView-2; Landsat 8; trädattribut; trädtäcke; biomassa; Random Forest;

    Sammanfattning : Woodlands constitute the subsistence base of the majority of people in the Sudano-Sahelian zone (SSZ), but low availability of in situ data on vegetation structure and composition hampers research and monitoring. This thesis explores the utility of remote sensing for mapping and analysing vegetation, primarily trees, in the SSZ. LÄS MER

  4. 3. Cosmogenic radionuclides in environmental archives – A paleo-perspective on space climate and a synchronizing tool for climate records

    Författare :Florian Mekhaldi; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Comogenic radionuclides; 10Be; 36Cl; Solar energetic particles; Solar storms; Paleoclimate; Time-scales; Solar activity;

    Sammanfattning : The Sun is the primary source for Earth’s climate system. Its fluctuations in irradiance are also known to have an impact on climate. In addition, changes in solar activity modulate the atmospheric production rates of cosmogenic radionuclides (e.g. LÄS MER

  5. 4. Speeding up the Atmosphere : Experimental oxidation studies of ambient and laboratory aerosols using a flow reactor

    Författare :Erik Ahlberg; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Secondary organic aerosols; oxidation flow reactor; volatile organic compounds; climate;

    Sammanfattning : Apart from gases, the air we breath consist of tiny, so called, aerosol particles. A cubic metre of air in a relatively clean environment can consist of several billion aerosol particles. The impact of these particles on human health and on climate is significant. LÄS MER

  7. 5. Global Savannah Phenology : Integrating Earth Observation, Ecosystem Modeling, and PhenoCams

    Författare :Niklas Boke-Olén; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Savannahs are land areas where grass and trees co-exists to create a landscape that is neither a grassland nor a forest. It is estimated that savannahs cover approximately one sixth of the global land surface. They also play an important role in the global carbon cycle due to their total size. LÄS MER
