    Nyckelord :Fall prevention; balance estimation; center of mass; center of pressure; human pose estimation; human keypoint detection; Fallprevention; balansestimering; tyngdpunkt; tryckcentrum; kroppshållningsestimation;

    Sammanfattning : The deep learning technique Human Pose Estimation (or Human Keypoint Detection) is a promising field in tracking a person and identifying its posture. As posture and balance are two closely related concepts, the use of human pose estimation could be applied to fall prevention. LÄS MER

  3. 2. Sunshade Demonstrator Spacecraft Earth Sphere of Influence Escape Using a Propellant-free AOCS

    Master-uppsats, KTH/Rymdteknik

    Författare :Leonardo Ricci; [2021]
    Nyckelord :Solar sail; Solar radiation pressure; Attitude control; Escape trajectory; Centre of pressure; Disturbance Torques; Eclipse.; Solsegel; Solstrålningstryck; Attitydkontroll; Flyktbana; Tryckcentrum; Störningsmoment; Eclipse.;

    Sammanfattning : This thesis provides insights to what is peculiar about a solar sail attitude and orbit control system and provides the assessment, in the form of a feasibility study, of the effectiveness of sail tip vanes as a control hardware to escape the Earth sphere of influence. The demonstrator aims to prove the technology for the Sunshade project, a constellation of solar sails located at the Lagrangian point L1 to obscure part of the solar radiation directed towards earth.
