  1. 36. Probabilistic Mapping of Spatial Motion Patterns for Mobile Robots

    Författare :Tomasz Piotr Kucner; Martin Magnusson; Achim Lilienthal; Tomás Krajník; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : To bring robots closer to real-world autonomy, it is necessary to equip them with tools allowing them to perceive, model and behave adequately to dynamic changes in the environment. The idea of incorporating information about dynamics not only in the robots reactive behaviours but also in global planning process stems from the fact that dynamic changes are typically not completely random and follow spatiotemporal patterns.

  3. 37. Applications of the Virtual Holonomic Constraints Approach : Analysis of Human Motor Patterns and Passive Walking Gaits

    Författare :Uwe Mettin; Anton Shiriaev; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motion Planning; Humanoid Robots; Virtual Holonomic Constraints; Underactuated Mechanical Systems; Mechanical Springs; Automatic control; Reglerteknik;

    Sammanfattning : In the field of robotics there is a great interest in developing strategies and algorithms to reproduce human-like behavior. One can think of human-like machines that may replace humans in hazardous working areas, perform enduring assembly tasks, serve the elderly and handicapped, etc. LÄS MER

  4. 38. Distribution and persistence of epiphyte metapopulations in dynamic landscapes

    Författare :Victor Johansson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Habitat loss is a major cause of species extinction. Old trees have declined, and this continues because of poor management. Examples are development of secondary woodland in semi-open grasslands, and lack of natural tree regeneration. We therefore can expect that species associated with old tree are declining. LÄS MER

  5. 39. Patterns of performance in new firms : estimating the effects of absorptive capacity

    Författare :Erik Wetter; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : New firms are crucial for economic growth and development, especially in the knowledge-intensive service and manufacturing industries that compose an increasing portion of developed economies. As many new firms fail and performance varies widely for surviving firms, studying new firm entry and pre-formation processes is necessary but not sufficient to create increased understanding of the important contribution of new firms to economic growth.

  7. 40. Network Management for Dynamic and Heterogeneous Wireless Sensor Networks

    Författare :Shunmuga Priyan Selvaraju; Mats Björkman; Ali Balador; Hossein Fotouhi; Maryam Vahabi; Cicek Cavdar; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Wireless Sensor Networks (WSNs) are interconnections of spatially distributed sensor nodes with low-power wireless communication. In comparison with traditional wireless networks, WSNs provide novel features in network architecture, which are known as low-cost networking, rapid formation, widespread arrangement, self-organisation, and ease of deployment.
