  1. 6. Selection on floral traits in Primula farinosa

    Författare :Didrik Vanhoenacker; Johan Ehrlén; Jon Ågren; Arjen Biere; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coevolution; correlational selection; Falseuncaria ruficiliana; geographic mosaic; hand pollination; Hermann Müller; interaction strength; plant-insect interactions; pollen limitation; selection strength; spatiotempora; Uta stansburiana; Biology; Biologi; Plant Ecology; växtekologi;

    Sammanfattning : Flowers and inflorescences have evolved in relation to animals for at least 100 million years. Plants attract pollinators with large, conspicuous, bright-coloured or scented flowers. These display attributes, however, also attract herbivores. LÄS MER

  3. 7. Relativistic light-matter interaction

    Författare :Tor Kjellsson Lindblom; Eva Lindroth; Bernard Piraux; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-dependent Dirac equation; Beyond dipole effects; Relativistic effects; High-Intensity laser-matter interaction; teoretisk fysik; Theoretical Physics;

    Sammanfattning : During the past decades, the development of laser technology has produced pulses with increasingly higher peak intensities. These can now be made such that their strength rivals, and even exceeds, the atomic potential at the typical distance of an electron from the nucleus. LÄS MER

  4. 8. Mediated and Mobile Communication for Experts

    Författare :Marcus Nilsson; Kristina Groth; Dag Svanæs; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beyond being there; trauma; mediated communication; mdtm; wearable computers; Människa-datorinteraktion; Human-computer Interaction;

    Sammanfattning : This thesis focuses on systems for mediated communication that run on mobile technology. The aim has been to give an answer to the question about what require- ments there are for situation awareness for domain experts when communication is secondary and supports the primary task.

  5. 9. Numerical and Experimental study of shock boundary layer interaction in unsteady transonic flow

    Författare :Olivier Bron; KTH; []
    Nyckelord :Shock Boundary Layer Interaction; Shock Motion; Unsteady Flows; Nozzle Flows; Potential Interaction; Back Pressure Perturbations;

    Sammanfattning : A prerequisite for aeroelastic stability prediction inturbomachines is the understanding of the fluctuatingaerodynamic forces acting on the blades. Unsteady transonicflows are complex because of mutual interactions betweentravelling pressure waves, outlet disturbances, shock motion,and fluctuating turbulent boundary layers. LÄS MER

  7. 10. Interaction strength and responses of ecological communities to disturbances

    Författare :Maria Christianou; Bo Ebenman; Peter de Ruiter; Linköpings universitet; []
    Nyckelord :Species deletion; secondary extinctions; keystone species; keystone links; species reintroductions; Lotka-Volterra models; local stability; permanence; resilience; sensitivity analysis; diversity; complexity; food webs; competition communities; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Ecological communities are continuously exposed to natural or anthropogenic disturbances of varied intensity and frequency. The way communities respond to disturbances can depend on various factors, such as number of species, structural characteristics of the community, stability properties, species characteristics and the nature of the disturbance.
