  1. 1. Pilot Study on Working Memory : Investigating Single Trial Decoding to Find the Best Stimulus and Target for a Future Personalized Neurofeedback

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Erik Gasparini; [2023]
    Nyckelord :Visual working memory; Personalised neurofeedback; Visual stimulus; Targeted brain region.;

    Sammanfattning : A standard Neurofeedback approach to mitigate the working memory decline in some fragile groups (elderly, subjects affected by stroke or Alzheimer's disease) can be suboptimal for some patients. The goal of this research is to investigate which visual stimulus (among colour, geometrical shape, direction, and symbol) is the most suited for each of the six healthy participants and which brain areas are the most discriminative, during the maintenance of a presented stimulus in a retro-cue-based working memory experiment.

  7. 5. Residual stresses in Ti-6Al-4V from low energy laser repair welding

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Peter Ericson; [2018]
    Nyckelord :Micro laser welding; Low energy welding; Ti-6Al-4V; Ti64; Residual stress; Response Surface Methodology; Repair welding; Welding simulation; Mikrolasersvetsning; Lågenergetisk svetsning; Lågenergisvets; Ti-6Al-4V; Ti64; Restspänningar; Response Surface Methodology; Reparationssvets; Svetssimulering;

    Sammanfattning : Millimeterstora och svårupptäckta defekter kan uppstå internt i stora och komplexa gjutgods av Ti-6Al-4V, ibland går dessa oupptäckta tills detaljen genomgått mekanisk bearbetning och en stor kostnad redan har gått in i den. Dessa defekter och andra industriella olyckshändelser leder till ett behov av additiva reparationsmetoder där den för tillfället rådande metoden är TIG-svetsning. LÄS MER
