  1. 1. Worse than Complex

    Författare :Petter Törnberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolutionary Developmental Theory; Complexity; Transitions; Naturalism; Innovation; Wicked Systems; Social Movements; Digital Trace Data; Innovation Society; Critical Realism;

    Sammanfattning : This thesis engages with questions on the boundary between what has traditionally been understood as social and natural. The introductory essay contextualizes the specific contributions of the included papers, by noting and exploring a reinvigoration of "naturalism" (the notion of a continuity between the human realm and the rest of natural phenomena) under the banner of Complexity Science.

  3. 2. Basal boundary conditions, stability and verification in glaciological numerical models

    Författare :Christian Helanow; Peter Jansson; Brian Hanson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glaciology; subglacial hydrology; ice sheet modeling; basal boundary conditions; non-linear Stokes flow; Physical Geography; naturgeografi;

    Sammanfattning : To increase our understanding of how ice sheets and glaciers interact with the climate system, numerical models have become an indispensable tool. However, the complexity of these systems and the natural limitation in computational power is reflected in the simplifications of the represented processes and the spatial and temporal resolution of the models.

  4. 3. Making transformation happen : Institutional entrepreneurship and boundary management in the Coral Triangle

    Författare :Franciska Rosen; Per Olsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This licentiate thesis sets out to investigate the dynamics of transformative change in social-ecological systems. That is, how large-scale sustainability transitions can be initiated and purposefully navigated. LÄS MER

  5. 4. Global stability and feedback control of boundary layer flows

    Författare :Espen Åkervik; Dan S. Henningson; Luca Brandt; Dwight Barkley; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stability; Global Stability; Feedback Control; Control; Estimation; Absolute Convective Instabilities; Model Reduction; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : In this thesis the stability of generic boundary layer flows is studied from a global viewpoint using optimization methods. Global eigenmodes of the incompressible linearized Navier-Stokes equations are computed using the Krylov subspace Arnoldi method. LÄS MER

  7. 5. On interface modeling  with emphasis on friction

    Författare :Anders Söderberg; Sören Andersson; Lars-Erik Stacke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface model; contact; friction; simulation; system behaviour; surface roughness; elastic foundation; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The general trend toward increased use of computer models and simulations during product development has led to a need for accurate and reliable product models. The function of many products relies on contact interfaces between interacting components. LÄS MER
