  1. 6. fMRI for mapping the plastic somatotopy of primary somatosensory cortex - Development and clinical applications

    Författare :Andreas Weibull; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smoothing; physiological noise; spatial resolution; primary somatosensory cortex; cortical reorganisation; brain plasticity; fMRI; partial volume effects;

    Sammanfattning : Functional magnetic resonance imaging (fMRI) is a widely used tool for studying brain function in vivo. The technique is based on acquiring brain images sensitive to the physiological response following neural activation, and hence, allows brain activity to be examined and documented. LÄS MER

  3. 7. Precise kinematic GPS positioning with Kalman filtering and smoothing

    Författare :Patric Jansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Global Positioning System (GPS) has proven to be auseful tool for the determination of positions of a widevariety of moving platforms to accuracies in the order of a fewcentimetres. One of the critical aspects of precise kinematicGPS positioning at the centimetre level is the determination ofinteger carrier phase cycle ambiguities. LÄS MER

  4. 8. Averaging level control in the presence of frequent inlet flow upsets

    Författare :Peter Rosander; Alf J. Isaksson; Johan Löfberg; Morten Hovd; Linköpings universitet; []
    Nyckelord :Averaging level control; PI control; Surge tanks; Optimal control; Robust MPC; Process control;

    Sammanfattning : Buffer tanks are widely used within the process industry to prevent flow variations from being directly propagated throughout a plant. The capacity of the tank is used to smoothly transfer inlet flow upsets to the outlet. Ideally, the tank thus works as a low pass filter where the available tank capacity limits the achievable flow smoothing. LÄS MER

  5. 9. Insuring Against Unemployment

    Författare :Jonas Kolsrud; Bertil Holmlund; Erling Barth; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; unemployment insurance; savings; consumption smoothing; Economics; Nationalekonomi;

    Sammanfattning : This paper studies optimal public unemployment insurance (UI) when workers have the possibility of topping-up public UI with private UI that is endogenous to public UI and subject to moral hazard. The issue is analyzed with a theoretical model in which publicly insured workers, who differ in layoff risk, hidden to the planner, are offered to top-up public UI with private UI. LÄS MER

  7. 10. On the Snell envelope approach to optimal switching and pricing Bermudan options

    Författare :Ali Hamdi; Boualem Djehiche; Henrik Hult; Said Hamadène; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of two papers related to systems of Snell envelopes. The first paper uses a system of Snell envelopes to formulate the problem of two-modes optimal switching for the full balance sheet in finite horizon. LÄS MER
