    Abstract : 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.

  4. 22. Geographical Information Systems (GIS) as a tool for analysis and communications of multidimensional data

    Author : Åke Sivertun; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Geographic Information Systems GIS ; Landscape Ecology; Artificial Drainage; Distributed Models; Environmental Change; Environmental Impact; Environmental Engineering; Landscape History; Drainage Technology; Historical Geography; Multidimensional and Multi-temporal Analysis; Hyperpixel; Colour Coding and Presentation of Multidimensional Data; Geografiska informationssystem;

    Abstract : An integrating approach, including knowledge about whole systems of processes, is essential in order to reach both development and environmental protection goals. In this thesis Geographical Information Systems (GIS) are suggested as a tool to realise such integrated models. READ MORE

  5. 23. A passage to wastewater nutrient recovery units : Microalgal-Bacterial bioreactors

    Author : Anbarasan Anbalagan; Jesus Zambrano; Sebastian Schwede; Carl-Fredrik Lindberg; Emma Nehrenheim; Francisco Gabriel Acién Fernández; Mälardalens högskola; []

    Abstract : In recent years, the microalgal–bacterial process has been considered to be a very attractive engineering solution for wastewater treatment. However, it has not been widely studied in the context of conventional wastewater treatment design under Swedish conditions. READ MORE

  6. 24. Sea Ice Concentration Estimation and Ice Type Classification from Dual-Frequency Satellite Synthetic Aperture Radar

    Author : Wiebke Aldenhoff; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sea ice concentration; sea ice; SAR imaging; sea ice classification; Fram Strait;

    Abstract : The sea ice cover in the Arctic has undergone dramatic changes in recent years. The perennial sea ice extent is decreasing by 12.2 % per decade while annual mean sea ice thickness has decreased by more than 2 m for the central Arctic Basin from 1975 to 2012. READ MORE

  7. 25. The political economy of emission standards : politics, business and the making of vehicle emission regulations in Sweden and Europe, 1960-1980s

    Author : Mattias Näsman; Ann-Kristin Bergquist; Kristina Söderholm; Per Högselius; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; history; car industry; environmental governance; environmental regulation; air pollution; transition; vehicle emissions; transnational; European integration; standards; knowledge creation; linking; delinking; expertise; business power; lobbying; California Effect Hypothesis; ekonomisk historia; Economic History; History; historia; sustainability; hållbarhet;

    Abstract : The purpose of this thesis is to contribute to an improved historical understanding of the challenges and complexities involved in constructing systems of governance of motor vehicle air pollution. The specific aim of the study is to explore the development of regulatory vehicle emission standards in Sweden between 1960 and the 1980s as well as to analyze this development within its broader European economic, regulatory and environmental policy context by adopting a transnational approach.
