  1. 1. Safety-Critical Teleoperation with Time-Varying Delays : MPC-CBF-based approaches for obstacle avoidance

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

    Författare :Riccardo Periotto; [2023]
    Nyckelord :Robust Control Barrier Functions RCBFs ; Model Predictive Control MPC ; Obstacle Avoidance; Time-Varying Delays; Teleoperation; Robust Control Barrier Functions RCBFs ; Model Predictive Control MPC ; Obstacle Avoidance; Time-Varying Delays; Teleoperation;

    Sammanfattning : The thesis focuses on the design of a control strategy for safety-critical remote teleoperation. The main goal is to make the controlled system track the desired velocity specified by a human operator while avoiding obstacles despite communication delays. LÄS MER

  3. 2. Mätning av cerebral blodflödeshastighet med transkraniell doppler under stegrat arbetsprov : Genomförbarhet och klinisk relevans

    Kandidat-uppsats, Umeå universitet/Avdelningen för fysioterapi

    Författare :Emanuel Ahlgren; Jonathan Boogh; [2023]
    Nyckelord :trancranial doppler; cerebral bloodflow velocity; middle cerebral artery; bicycle ergometry tests; partial pressure end-tidal carbondioxide; transkraniell doppler; cerebral blodflödeshastighet; arteria cerebri media; ergometercykeltest; partialtryck end-tidal koldioxid;

    Sammanfattning : Bakgrund: Hjärnskakning är en vanlig diagnos och vissa patienter upplever att fysisk ansträngning utlöser symtom lång tid efter hjärnskakningen. En förändring i reglering av cerebralt blodflöde (CBF) har visats vara en potentiell orsak bakom detta. LÄS MER

  4. 3. Psilocybin Induced Psychedelic Experiences : their Neural Mechanisms and Efficacy for Treating Depressive Disorders

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Linda Lindecrantz; Nicklas Villman; [2023]
    Nyckelord :psilocybin; depression; fMRI; systematic review; DMN;

    Sammanfattning : The aim of this systematic review is to present the current literature on the therapeutic potential of the classic psychedelic compound psilocybin for depressive disorders and the neurocognitive mechanisms involved recorded with functional magnetic resonance imaging (fMRI). A comprehensive literature search was conducted in the electronic databases Web of Science, Scopus and Medline EBSCO using a Boolean search string containing the keywords psilocybin, depression, fMRI, MRI and PET.
