  4. 17. On Specifying and Estimating Economic Growth as a Spatial Process : Convergence, Inequality, and Migration

    Author : Martin E. Gustafsson; Roger Bivand; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Economic geography; economic growth; regional convergence; migration; spatial statistics; spatially correlated errors; geographical dependence; Kulturgeografi; Human geography; Kulturgeografi; kulturgeografi; Social and Economic Geography;

    Abstract : This thesis includes three self-contained papers. The first paper considers the effect of geographically dependent observations on cross-sectional growth convergence and proposes a way of decomposing the level of technology taking into account geographical variation in growth rates.

  5. 18. Online Learning for Energy Efficient Navigation in Stochastic Transport Networks

    Author : Niklas Åkerblom; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Thompson Sampling; Online Minimax Path Problem; Multi-Armed Bandits; Online Learning; Online Shortest Path Problem; Machine Learning; Combinatorial Semi-Bandits; Energy Efficient Navigation;

    Abstract : Reducing the dependence on fossil fuels in the transport sector is crucial to have a realistic chance of halting climate change. The automotive industry is, therefore, transitioning towards an electrified future at an unprecedented pace. READ MORE

  6. 19. Localization of N=2 Field Theories: a Twisted Path Across Four Manifolds

    Author : Lorenzo Ruggeri; Guido Festuccia; Stefano Cremonesi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supersymmmetry; gauge theories; localization;

    Abstract : Supersymmetric quantum field theories provide a framework where certain physical observables can be computed exactly. In those cases, one not only has control over perturbative contributions but also over non-perturbative contributions. READ MORE

  7. 20. Parametric stability analyses for fluid-loaded thin membranes

    Author : Yang Zhou; Anders Eriksson; Håkan Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membranes; Hydro-static load; Multi-parametric loading; Bifurcations; Generalized path-following; Fold lines; Mesh eects; Augmenting equations; Generalized eigenproblem; Solution surface.; Engineering Mechanics; Teknisk mekanik;

    Abstract : Membrane structures are commonly used in many elds. The studies of thesestructures are of increasing interest. The two projects focus on the evaluations ofequilibrium states for uid-pressurized membranes under dierent loading conditions,and the corresponding instability behavior. READ MORE
