    Författare :Ignacio Solís Marcos; Katja Kircher; Alejandro Galvao; Tuomo Kujala; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Partial automation; human factors; event-related potentials; cognitive underload; task interference; additional task; automation experience; automation trust; Partial automation; mänskliga faktorer; Eventrelaterade potentialer; kognitiv underbelastning; arbetsstörningar; sidouppgift; automatiseringserfarenhet; automatiseringsförtroende;

    Sammanfattning : The technological development in recent years is currently reflected in the implementation of more and more advanced driver assistance systems (ADAS). A clear example is found in the automated driving systems being marketed today. LÄS MER

  2. 2. Aspects of Energy Resource Management

    Författare :Tomas Kåberger; Chalmers University of Technology; []
    Nyckelord :bio-energy; value; interdisciplinary; life-cycle analysis; tax-shift; resource; energy; electricity;

    Sammanfattning : Energy resource management requires input from many disciplines. The three first papers in this thesis deals with the use of physical terms in the interdisciplinary process where inputs from different disciplines are handled together. LÄS MER

  3. 3. Reproductive allocation and costs of reproduction in subarctic herbs : A resource-based perspective

    Författare :Åsa M. Hemborg; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ecology; Altitudinal gradient; Plant size; Predispersal seed predation; Reproductive effort; Resource dynamics; Seasonal variation; Sexual dimorphism; Somatic costs; Unisexual plants; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : The influence of internal and external factors on two major plant life history components, i.e., reproductive allocation and costs of reproduction, was examined for nine perennial herbs in subarctic Swedish Lapland. In one study, comparisons were made between Sweden and the French Alps. LÄS MER

  4. 4. The EU´s Collective Use of Force : Exploring the Factors behind its First Military Operations

    Sammanfattning : The EU has since 2003 carried out six military operations.  This thesis seeks to determine the circumstances under which the EU will, or will not, undertake military operations. LÄS MER

  5. 5. Mechanisms structuring the pelagic microbial food web : Importance of resource and predation

    Författare :Kristina Samuelsson; Agneta Andersson; Christiane Lancelot; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ecology; pelagic microbial food web; bacteria; flagellates; ciliates; phytoplankton; mixotrophy; nutrient status; predation limitation; resource limitation; Baltic Sea; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Temporal and spatial variations of pelagic microorganisms in the northern Baltic Sea were studied, as well as factors influencing their abundance and growth rates. Three main questions were asked 1) How does increased productivity influence the structure of the microbial food web? 2) Does predation limitation vary between trophic levels? 3) What is the relative importance of resource and predation limitation at different trophic levels?A field study in the northern Baltic Sea showed that dominating protozoa, flagellates and ciliates, increased with increasing primary productivity from north to south.
