  1. 1. Finding new members of the VelHel-4 stream

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

    Författare :Lucas Johansson; [2023]
    Nyckelord :Galactic Archaeology; Milky Way; Stellar Streams; Streams; Stellar Halo; Stars; Globular Cluster; Astronomy; Astrophysics; Gaia; Chemical Abundance; Spectroscopy;

    Sammanfattning : According to the paradigm of lambda-CDM cosmology, the stellar halo ofour Galaxy has been built-up over time through the accretion of other galaxiesand star clusters. The remnants of some of these are still observable today asstellar streams, but are typically very faint and difficult to resolve amidst the farmore numerous foreground Milky Way stars. LÄS MER

  3. 2. Assessment of Shoulder Biomechanics during Pull-up Techniques

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Mariah Sabioni; [2023]
    Nyckelord :strength training; biomechanics; motion analysis; shoulder; styrketräning; biomekanik; rörelseanalys; axel;

    Sammanfattning : CrossFit® has gained popularity as a functional training method that caters to individuals with varying levels of fitness, including those with little to no athletic background. Regardless, shoulders represent the highest injury rate in this sport, most frequently associated with pull-up variations. LÄS MER

    Sammanfattning : Reinforcement learning (RL) has seen a fast expansion in recent years of its successful application to a range of decision-making and complex control tasks. Moreover, deep learning offers RL the opportunity to enlarge its spectrum of complex fields. LÄS MER

  5. 4. Validation of a new iPhone application for measurements of wrist velocity during actual work tasks

    Master-uppsats, KTH/Ergonomi

    Författare :Mohammed Abderhman Abaid; [2023]
    Nyckelord :Angular velocity; goniometer; inertial Measurement Unit IMU ; “ErgoHandMeter”; percentile; correlation iii; Vinkelhastighet; goniometer; IMU ; ErgoHandMeter ; percentil; korrelation;

    Sammanfattning : The breakthrough in mobile technology and the development of smartphones, supplied with sensing devices such as Inertial Measurement Units (IMUs), has made it possible to obtain accurate and reliable data on the angular velocity for different objects. The available technical sensors for wrist movements, such as electrogoniometers, are costly, time-consuming, and need a particular computer program to be analyzed. LÄS MER

  7. 5. Airspeed estimation of aircraft using two different models and nonlinear observers

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Alexander Roser; Anton Thunberg; [2023]
    Nyckelord :sensor fusion; flight mechanics; Kalman filter; extended Kalman filter; unscented Kalman filter; pitot tube; airspeed estimation; simulation;

    Sammanfattning : When operating an aircraft, inaccurate measurements can have devastating consequences. For example, when measuring airspeed using a pitot tube, icing effects and other faults can result in erroneous measurements. LÄS MER
