  1. 1. Koopman mode analysis of the side-by-side cylinder wake

    University essay from KTH/Mekanik

    Author : Jimmy Röjsel; [2017]
    Keywords : Bluff body; wake flow; Side-by-side cylinder wake; Flip-op instability; Modal analysis; Koopman operator; Koopman mode decomposition;

    Abstract : In many situations, fluid flows can exhibit a wide range of temporal and spatial phenomena. It has become common to extract physically important features, called modes, as a first step in the analysis of flows with high complexity. READ MORE

  2. 2. Catch the dream Wave : Propagation of Cortical Slow Oscillation to the Striatum in anaesthetised mice

    University essay from KTH/Beräkningsbiologi, CB

    Author : Tiago Ferreira; [2014]
    Keywords : Cortex; Striatum; anaesthesia; slow oscillation; spontaneous activity; ketamine; in vivo; up states; wavelet; MUA; high-gamma range; MSNs;

    Abstract : Under anaesthesia or in deep sleep, different parts of the brain have a distinctive slow oscillatory activity, characterised by states of high membrane potential and intensive spiking activity, the Up-states; followed by hyperpolarisation and quiescence, the Down-states. This activity has been previously described in vitro and in vivo in the cortex and the striatum, across several species. READ MORE
