  1. 1. Safe Reinforcement Learning for Social Human-Robot Interaction : Shielding for Appropriate Backchanneling Behavior

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mohamed Akif; [2023]
    Keywords : Human-Robot Interaction; Backchanneling; Social Robots; Safe Reinforcement Learning; Shielding; Recurrent Neural Network; Gated Recurrent Unit; Människa-Robot Interaktion; Uppbackning; Sociala Robotar; Säker Förstärkningsinlärning; Avskärmning; Återkommande Neurala Nätverk; Gated Återkommande Enhet;

    Abstract : Achieving appropriate and natural backchanneling behavior in social robots remains a challenge in Human-Robot Interaction (HRI). This thesis addresses this issue by utilizing methods from Safe Reinforcement Learning in particular shielding to improve social robot backchanneling behavior. READ MORE

  3. 2. Deep Learning for the prediction of RASER-MRI profiles

    University essay from Linköpings universitet/Medie- och Informationsteknik

    Author : Filip Arvidsson; Jonas Bertilson; [2023]
    Keywords : MRI; NMR; AI; Deep Learning; RASER-MRI; Media Technology; KIT; LIU; CNN; Autoencoder; Djupinlärning; Medieteknik; Magnetröntgen;

    Abstract : Magnetic resonance imaging (MRI) is a critical diagnostic tool in medical practice, enabling non-invasive visualization of anatomy and physiological processes. Nonetheless, MRI has inherent spatial resolution limitations, which may limit its diagnostic capabilities. READ MORE

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

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Linda Lindecrantz; Nicklas Villman; [2023]
    Keywords : psilocybin; depression; fMRI; systematic review; DMN;

    Abstract : 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.

  5. 4. Radiofrequency-Induced Heating of a Deep Brain Stimulator Lead inside TEM Cells and inside a 3T MR-Scanner

    University essay from Umeå universitet/Radiofysik

    Author : Haider Shaban; [2022]
    Keywords : Medical Physics; MRI; ;

    Abstract : The use of non-ionizing radiation in the magnetic resonance imaging (MRI) made it a safer diagnostic technique in comparison to the X-ray imaging method. MRI can also produce soft tissue images with a very high contrast without contrast agent which is another advantage that made MRI an important imaging technique for studying the mechanism of the deep brain stimulation (DBS) and for targeting the desired regions in the brain that should be stimulated.

  6. 5. Word embeddings and Patient records : The identification of MRI risk patients

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Erik Kindberg; [2019]
    Keywords : word2vec; word embeddings; patient records; MRI safety; digital healthcare;

    Abstract : Identification of risks ahead of MRI examinations is identified as a cumbersome and time-consuming process at the Linköping University Hospital radiology clinic. The hospital staff often have to search through large amounts of unstructured patient data to find information about implants. READ MORE
