  1. 21. 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

  3. 22. Inverkan av uppmärksamhetsfokus på utförandet av knäböj på vippbräda : med jämförelse mellan personer med främre korsbandsrekonstruktion och personer utan knäskada

    Kandidat-uppsats, Umeå universitet/Avdelningen för fysioterapi

    Författare :Jesper Kallin; Oscar Kallings; [2023]
    Nyckelord :External focus; internal focus; balance; movement smoothness; knee joint; kinematic; Externt fokus; internt fokus; balans; rörelseflyt; knäled; kinematik;

    Sammanfattning : Bakgrund: Uppmärksamhetsfokus på omgivningen/externt fokus har återkommande visat förbättra motorisk färdighet, inlärning och prestation under flertalet olika motoriska uppgifter i jämförelse med fokus på egna kroppen/internt fokus. Instruktioner som uppmuntrar till internt fokus är mer förekommande vid rehabiliteringen av skador som ruptur av främre korsbandet, däremot har externt fokus visats påverka kinematiska variabler som kan minska risken för återskada.

  4. 23. Noggrannhet av RTK-GPS-positionering av enskilda frön vid precisionssådd

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Oskar Wikfeldt; Christoffer Pålsson Andersson; [2023]
    Nyckelord :Agriculture; Individual plant care; RTK; GPS; GNSS; Geo-referencing; Seed mapping; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : With higher demands on farmers to reduce the usage of fertilizers and pes ti cides because of their negative environmental impact, as well as the rising prices of resources required for agriculture, precision agriculture has become a big focus in today’s agriculture research. Individual plant care systems are a big part of precision agriculture, and accurate information about the po si tions of individual plants is required for these systems. LÄS MER

  5. 24. Design, Modeling, and Testing of a Force Feedback Haptic Device for Simulated Robot Interaction

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Patrik Lindström; [2023]
    Nyckelord :Force Feedback; Impedance Control; PD-gain; Dynamic Behavior; Closed-chain; Master-Slave; Parallel Manipulator; Kinematics Redundancy; Mass-Spring-Damper; Position Control; Current Control; Modeling; Design; Joints; Delta robot; Differential Equations; External Torques; Kinematics; Forward Kinematics; Inverse Kinematics; Dynamic Matrices; Jacobian; URDF; Haptics; Haptic Device; Solidworks; CAD; Maxon Motors; EtherCAT; Beckhoff;

    Sammanfattning : Haptic feedback is a growing phenomenon that incorporates the sense of touch through tactile sensations such as vibrations, electrical signals, air pressure, and sound waves or through force feedback, which employs torques and/or forces to replicate the pressure and weight of a simulated object. Utilizing haptic technology establishes a communication bridge between the user and the technical component, enhancing the user's understanding of the technical component's surroundings. LÄS MER

  7. 25. Studies of the J/Ψ → anti-Σ0Σ0 Reaction with BESIII : Event Selection Development

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Benjamin Verbeek; [2023]
    Nyckelord :hyperon; CP; symmetry; event selection; tracks; BES; BESIII; USTC;

    Sammanfattning : The apparent symmetry between matter and antimatter raises the question of why the universe consists of mostly matter. Via an academic exchange to USTC Hefei, a reaction was studied that aims to give insight into this question. LÄS MER
