  1. 1. Dissolved organic carbon in tropical watersheds : Linking field observation and eco-hydrological modelling

    Författare :Fabien Rizinjirabake; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dissolved organic carbon DOC ; Rwanda; Land use land cover variability; Climate variability and change; Rukarara River Watershed; eco-hydrological modelling; field observation;

    Sammanfattning : Dissolved organic carbon (DOC) is a general description of the organic material dissolved in water. DOC is an important source of energy, carbon, and nutrient transfers from terrestrial to aquatic ecosystems. The export of DOC into aquatic ecosystems may contribute to the carbon balance of terrestrial ecosystems and to water degradation. LÄS MER

  2. 2. Fritidssektorn : en statlig utmaning

    Författare :Lisbeth Lindström; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pedagogik; Education;

    Sammanfattning : The leisure sector, for example sports and games, has witnessed a tremendous expansion between 1960 and the present. During the last ten years the private sector led by companies, economic associations, foundations and many businesses have expanded their involvement in the leisure sector. LÄS MER

  3. 3. Multi-Camera Light Field Capture : Synchronization, Calibration, Depth Uncertainty, and System Design

    Författare :Elijs Dima; Mårten Sjöström; Roger Olsson; Ulf Assarsson; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Light field; Camera systems; Multiview; Synchronization; Camera calibration;

    Sammanfattning : The digital camera is the technological counterpart to the human eye, enabling the observation and recording of events in the natural world. Since modern life increasingly depends on digital systems, cameras and especially multiple-camera systems are being widely used in applications that affect our society, ranging from multimedia production and surveillance to self-driving robot localization.

  4. 4. Residual and critical saturation in geological storage of CO2 : results from field studies, pore-network modelling and laboratory experiments

    Författare :Ramin Moghadasi; Auli Niemi; Philip Ringrose; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geological CO2 storage; Residual trapping; Gas remobilization; Field experiment; Numerical modelling; Pore-network modelling; Pore-scale imaging;

    Sammanfattning : Geological storage of CO2 in deep saline aquifers is a promising technology in the combat to reduce the atmospheric emissions of CO2. A critical component in this solution is the estimation of aquifer’s in situ capability to store CO2. LÄS MER

  5. 5. Optics for Earth Observation Instruments

    Författare :Arvid Hammar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; off-axis; free-form mirrors; measurements; stray light; spline horns; THz; reflector optics; satellites; scientific instruments; diamond turning; tolerancing; telescopes;

    Sammanfattning : The optical system is an essential part of every remote sensing instrument used for detecting electromagnetic waves. Careful design, fabrication and characterization is therefore crucial, especially for satellite-borne missions where the possibility of post-launch repairs is highly limited. LÄS MER
