  1. 1. Urban Mobility Transitions : Governing through Experimentationin Bristol and New York City

    Författare :Emilia Smeds; Jenny McArthur; Helena Titheridge; Tim Schwanen; Yvonne Rydin; University College London Engineering and Public Policy Technology Department of Science; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transport; transitions; urban governance; experimentation; mobility;

    Sammanfattning : Transitions away from car-dominance is one of the key debates in urban research, policy and practice today. Car-free public space, cycling and convenient public transport services are widely seen as desirable, yet the reconfiguration of our streets and transport networks has been incremental. LÄS MER

  3. 2. Phase transitions in high-temperature superconductors

    Författare :Jack Lidmar; KTH; []
    Nyckelord :Superconductivity; Vortices; Phase transitions; Strongly correlated fermions; High-temperature superconductivity; Monte Carlo simulations.; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Thermal fluctuations and disorder strongly influence the behaviour of hightemperature superconductors. In particular the vortices play a key role in determining their properties. In this thesis the main focus lies on phase transitions, both in ultra-thin films and in three-dimensional systems, which are driven by vortex fluctuations. LÄS MER

  4. 3. Workload transitions and stress : changes over time

    Författare :Erik Prytz; Mark Scerbo; USA VA Norfolk Old Dominion University Department of Psychology; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; human factors; workload transition; stress; workload;

    Sammanfattning : Workload transitions are situations where operators are suddenly confronted with levels of workload substantially different from previously established levels. Workload transitions may affect the operators' state of stress and coping behaviors but previous research has not conclusively demonstrated the nature of those. LÄS MER

  5. 4. Guiding Sustainability Transitions: Backcasting, Experimentation and Social learning

    Författare :Johan Larsson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sustainability transitions; transdisciplinarity; reflexive governance; experimentation; backcasting; Education for Sustainable Development ESD ; social learning;

    Sammanfattning : Sustainability challenges including climate change, social injustice, resource depletion and biodiversity loss are becoming increasingly apparent. These challenges can be understood as partly resulting from unsustainable socio-technical systems in society, assumed to require transitions to become sustainable in time. LÄS MER

  7. 5. Phase transitions in magnetic metamaterials

    Författare :Björn Erik Skovdal; Björgvin Hjörvarsson; Vassilios Kapaklis; Gunnar K. Pálsson; Peter Schiffer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic metamaterials; artificial spin ice; mesospins; magnetic nanostructures; mesoscopic spin systems; multiscale materials; tri-criticality; emergence; edge modes;

    Sammanfattning : Magnetic metamaterials consisting of arrays of densely packed, two-dimensional nanoscale magnetic islands have degrees of freedom on two separate length scales: inside the islands, and among them. These degrees of freedom can be tuned by e.g. size, shape, island separation and lattice geometry. LÄS MER
