  1. 1. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Arvin Razavi; [2023]
    Nyckelord :IMU wrist angle estimation; Wrist absolute angle; IMU-based human motion capture; orientation filter; Complementary filter; Kalman filter; IMU handledsvinkeluppskattning; handleds absolutvinkel; IMU-baserad mänsklig rörelsefångst; orienteringsfilter; komplementfilter; Kalman-filter;

    Sammanfattning : Hand-intensive work is closely related to the prevalence of upper body and hand/wrist work-related musculoskeletal disorders (WMSDs) in office work, manufacturing, service industries, as well as the healthcare industry. Some risk factors include vibrations, forceful exertions, heavy manual handling, repetitive motions, and prolonged nonneutral wrist postures. LÄS MER

  3. 2. Comparison of Autofocus Methods for Highly Reflective Surfaces : A Case Study on the Inspection of Optical Filters

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Axel Hedvall; [2023]
    Nyckelord :autofocus; reflective surface; optical filter; visual inspection; autofokus; reflekterande yta; optiskt filter; visuell inspektion;

    Sammanfattning : Visual inspection is a crucial final step when manufacturing products, as it determines if a product can be sold or rejected. The inspection is often performed manually by trained inspectors, which is time-consuming and often subjective. By automating the inspection, it can be performed faster and more accurately. LÄS MER

  4. 3. Properties of the Optical Hot Spots in the Circumstellar Ring of SN 1987A

    Master-uppsats, KTH/Fysik

    Författare :Christos Tegkelidis; [2023]
    Nyckelord :;

    Sammanfattning : The proximity of Supernova 1987A provides a great opportunity to study the aftermath of the impact of the ejecta with the dense clumps (observed as ”hot spots”) located in the equatorial circumstellar ring. This thesis examines the properties of the clumps by using Hubble Space Telescope optical imaging taken with the F625W and F675W broad filters between 1994 and 2022. LÄS MER

  5. 4. Development of a Deep-space-capable Navigation System for the Hugin Space Exploration Technology Demonstration Satellite Mission

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Axel Widenfelt; [2021]
    Nyckelord :Autonomous optical navigation; Autonom optisk navigering;

    Sammanfattning : Development of autonomous in-fight navigation capability for a CubeSat mission is a challenging task, often ignored in favour of relying on a Global Navigation Satellite System (GNSS). However, the potential value in solving this problem becomes great for deep-space missions where such networks have limited coverage. LÄS MER

  7. 5. Bandpassfiltrering i optiska fibrer för kvantkommunikationssystem : Konstruktion och testning

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Nikki Wang; Pelle Nydahl; [2021]
    Nyckelord :;

    Sammanfattning : Kvantkommunikation är konsten att överföra information med hjälp av qubitar. Qubitar har likt en vanlig bit två tillstånd, 0 och 1, men kan dessutom befinna sig i en superposition av båda tillstånden. Genom att använda kvantmekanikens lagar gör kvantkommunikation det omöjligt för en tredje part att avlyssna information som överförs. LÄS MER
