  1. 1. Measurement of timescales of cortical neuronal activity in behaving mice

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sasa Lekic; [2021]
    Nyckelord :Neural activity; prefrontal cortex; visual cortex; Timescale; Spike trains; Functional hierarchy; Neural aktivitet; PFC; Timescale; Spike train; Funktionell hierarki;

    Sammanfattning : Electrical activity is omnipresent throughout the brain, and it varies dependant on the brain region. Areal hierarchy has been suggested to be one of the main principles of the organization of the brain, but there is not a lot of evidence available related to the specialization of the brain’s regions in the temporal domain, that is, how the activity evolves over time.

  3. 2. Investigating differences in the decay of divorce-induced residential mobility across gender and urbanisation

    Master-uppsats, Malmö universitet/Fakulteten för kultur och samhälle (KS)

    Författare :Matthew Gareth Bevan; [2019]
    Nyckelord :Divorce; Effect; Gender; Residential Mobility; Time; Urbanisation;

    Sammanfattning : Divorce is a life course event that triggers deviant, negative residential moves that symbolises the antithesis of climbing the traditional housing ladder, and sets individuals on an altered housing trajectory, typically associated with long-term instability compared to married counterparts. Studies have revealed that long-term instability associated with divorce is commonly connected to an increased probability of moving out of owner occupation that is greater and persists longer for women than men.

  4. 3. Possibilities and Challenges in Temporal Control of XUV Pulses by Opto-optical Modulation

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Anna Olofsson; [2018]
    Nyckelord :Quantum Control; Atomic physics; ultrashort pulses; attosecond science; ultrafast optics; nonlinear optics; opto-optic modulator; Physics and Astronomy;

    Sammanfattning : Recent developments in opto-optical modulation technique calls for improved temporal control of light modulation processes of coherent XUV light. This thesis project evaluates an experimental method aimed at achieving redirection and amplitude modulation of XUV-light, by using precise determination of decay times in states of noble gases that are deemed suitable for opto-optical control.

  5. 4. A study on the effects of the process parameters of polymerised HMDSO using RF-PECVD in corrosion protection applications

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Madeleine Ardic; Anton Gifvars; [2017]
    Nyckelord :;

    Sammanfattning : In this master thesis the effects of the process parameters of pp-HMDSO were studied in the application of corrosion protection of an Al surface. The method for polymerising the HMDSO vapour was RF-PECVD. LÄS MER

  7. 5. Study of Proton Emission in Complex Nuclei

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Jonatan Adolfsson; [2016]
    Nyckelord :Nuclear physics; Nuclear theory; Nuclei far from stability; Proton decay; Cobalt-53; Physics and Astronomy;

    Sammanfattning : In a recent experiment, the partial half-life ([i]t[/i][sub]1/2[/sub]) of proton emission from the [i]I[/i][sup]π[/sup] = 19/2[sup]-[/sup] state of [sup]53[/sup]Co was accurately measured. A previous estimate is [i]t[/i][sub]1/2[/sub] ~ 17 s. LÄS MER
