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

    Författare :Léa Prémont; [2023]
    Nyckelord :Augmented reality; Alzheimer’s disease; Navigation; Assistive technology; HoloLens 2; Optical See-Through; Localization; Kalman filter; Hologram; TLX; SUS; Réalité augmentée; Alzheimer; Navigation; Technologie d’assistance; HoloLens 2; Optical See-Through; Localisation; Filtre de Kalman; Hologramme; TLX; SUS; Förstärkt verklighet; Alzheimers sjukdom; Navigering; Tekniska hjälpmedel; HoloLens 2; Optisk genomskinlighet; Lokalisering; Kalman-filter; Hologram; TLX; SUS;

    Sammanfattning : This paper investigates the potential of augmented reality (AR) as a navigational aid for individuals with Alzheimer’s disease (AD), offering innovative solutions to the evolving challenges of AD care. As the disease progresses, patients often require more assistance and may transition to care centers, resulting in reduced independence. LÄS MER

  4. 3. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Marie Defives; [2022]
    Nyckelord :Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Sammanfattning : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. LÄS MER

  5. 4. Detailed chemical abundances of neutron-capture elements - from 523 local giant stars

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Rebecca Forsberg; [2019]
    Nyckelord :The Milky Way galaxy; Abundances; High-resolution spectroscopy; Neutron-capture elements; Physics and Astronomy;

    Sammanfattning : Purpose: The purpose of this work is to determine the abundances of neutron-capture elements in solar neighborhood giant stars. This enables constraints to be put on the the cosmic origin of these elements. LÄS MER

  7. 5. Optical Analysis of the Hydrogen Cooling Film in High Pressure Combustion Chambers

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Fabian Weber; [2019]
    Nyckelord :optical; analysis; hydrogen; h2; cooling; film; high; pressure; combustion; chambers; rocket; engine; thrust; experimental; oh*; shadowgraphy; flame; emission; lox; liquid; bipropellant; cryogenic; efficiency; heat; flux;

    Sammanfattning : For performance optimisation of modern liquid cryogenic bipropellant rocket combustion chambers, one component which plays an important role in reducing the wall side heat flux, is the behaviour of the cooling film. At the Institute of Space Propulsion of the German Aerospace Center (DLR) in Lampoldshausen, hot test runs have been performed using the experimental combustion chamber BKM, to investigate the wall side heat flux which is -- among other factors -- dependent on cooling film properties.
