  1. 6. On Robot Control using Range Sensors : with Special Reference to Active Uncertainty Reduction

    Författare :Bernt Nilsson; Aarne Halme; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robot Gripping and Docking; Gripper-Object Feedback; Non-contact Sensing; Laser Ranging; Flexible Arm; Mobile Robot; Probing; Dual Control; LQG-Feedback;

    Sammanfattning : This thesis addresses the problem of positioning robots relative to objects in the surrounding work space. The object's position and orientation (posture) are measured using a non-contact sensor on-board the robot. For gripping/docking tasks the goal posture is specified relative to the object and not in a fixed coordinate system of the robot. LÄS MER

  3. 7. Particle transport in human lung : effects of particle size and shape

    Författare :Sofie Högberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Recent studies have shown that nanoparticles may be more toxic than larger particles of the same material, but the health risks associated with widespread use largely depend on the extent of exposure. When dealing with potentially toxic particles, precautionary measures have to be taken in order to minimize contact. LÄS MER

  4. 8. Beyond Generative Sufficiency : On Interactions, Heterogeneity & Middle-Range Dynamics

    Författare :Martin Arvidsson; Peter Hedström; Marc Keuschnigg; Duncan Watts; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Collective dynamics; Social networks; Heterogeneity; Digital trace data; Agent-based simulation; Social mechanisms; Analytical sociology; Computational social science;

    Sammanfattning : Explaining how properties at the level of individuals translate into properties at the level of collectives is a core objective of sociology. Because the social world is characterized by complex webs of social interdependencies, establishing how micro and macro are related to one another requires a detailed understanding of how individuals are influenced by their social environments and the consequences that such influences have for the dynamics of the social process.

  5. 9. Genetic variation in structured populations

    Författare :Marina Rafajlovic; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; genetic variation; varying population size; effective population size; mutation; recombination; migration; multiple paternity; geographic structure; tests of neutrality; gene tree; species tree;

    Sammanfattning : It is widely acknowledged that the process of speciation in the presence of gene flow between different ecotypes is common in nature. However, the mechanisms underlying speciation are not understood. LÄS MER
