  1. 1. Social learning in the Anthropocene Governance of natural resources in human dominated systems

    Detta är en avhandling från Stockholm : Department of Systems Ecology, Stockholm University

    Författare :Björn Nykvist; Jon Norberg; Marianne Krasny; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; social learning; multi-level governance; resilience; adaptability; natural resource management; institutions; policy making; impact assessments; Natural Resources Management; naturresurshushållning;

    Sammanfattning : We live in the Anthropocene – an age where humans dominate natural systems – and there is ample evidence that our current practices degrade the capacity of natural systems to provide us with natural resources. How we, as humans, organize and learn, in communities and among state and other societal actors, constitute a decisive factor for both local management of natural resources and the functioning of the planet Earth.

  2. 2. Convergence in mixed reality-virtuality environments facilitating natural user behavior

    Detta är en avhandling från Örebro : Örebro universitet

    Författare :Daniel Johansson; Leo J. de Vin; Morten Fjeld; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mixed reality. augmented reality; augmented virtuality; head mounted display; omnidirectional floor; natural interface; telepresence; Computer and Systems Science; Datalogi;

    Sammanfattning : This thesis addresses the subject of converging real and virtual environments to a combined entity that can facilitate physiologically complying interfaces for the purpose of training. Based on the mobility and physiological demands of dismounted soldiers, the base assumption is that greater immersion means better learning and potentially higher training transfer. LÄS MER

  3. 3. Modelling of the Fletcher-Gent effect and obtaining hyperelastic parameters for filled elastomers

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Rickard Österlöf; Leif Kari; Per-Erik Austrell; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; filled elastomers; natural rubber; carbon black; Fletcher-Gent effect; Payne-effect; finite strain; hyperelastic;

    Sammanfattning : The strain amplitude dependency , i.e. the Fletcher-Gent effect and Payne effect, and the strain rate dependency of rubber with reinforcing fillers is modelled using a modified boundary surface model and implemented uniaxially. LÄS MER

  4. 4. Organizational Lessons Learned Natural Hazards Affecting Critical Infrastructure

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Monika Rydstedt Nyman; Lars Nyberg; Magnus Johansson; Eva Liljegren; Henrik Tehler; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; natural hazards; critical infrastructure; feedback; lessons learned; collective learning; memory building; Risk and Environmental Studies; Risk- och Miljöstudier;

    Sammanfattning : This thesis focuses on an issue often presented as a solution – albeit a debated one ­– namely learning, specifically lessons learned from natural hazard events. Empirically, this thesis examines flooding and avalanches in a Swedish context, centering on systematic feedback mechanisms and learning from extreme events. LÄS MER
