  1. 1. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Klara Stefansson; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. LÄS MER

  3. 2. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Erik Axelsson; Sebastian Fagerstedt; [2023]
    Nyckelord :Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Sammanfattning : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. LÄS MER

  4. 3. Design and Implementation of a Rocket Launcher Hybrid Navigation

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Omar Ugolini; [2023]
    Nyckelord :launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

    Sammanfattning : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.

  5. 4. Data Driven Modeling for Aerodynamic Coefficients

    Master-uppsats, KTH/Matematisk statistik

    Författare :Erik Jonsäll; Emma Mattsson; [2023]
    Nyckelord :Master s thesis; System identification; Parameter estimation; Ordinary least squares; Machine learning; Aerodynamic coefficients; F18--HARV; Flight simulations.; Masteruppsats; Systemidentifiering; Parameteruppskattning; Minstakvadratmetoden; Maskininlärning; Aerodynamiska koefficienter; F18-HARV; Flygsimuleringar.;

    Sammanfattning : Accurately modeling aerodynamic forces and moments are crucial for understanding thebehavior of an aircraft when performing various maneuvers at different flight conditions.However, this task is challenging due to complex nonlinear dependencies on manydifferent parameters.

  7. 5. Detecting Successful Throws

    Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Sami Almousa; Gorgis Morad; [2023]
    Nyckelord :Robotics; Trajectory estimation; Object detection; ROS; Computer Engineering;

    Sammanfattning : This project aims to create a robot system that can accurately figure out if the throws are successful. This can help make various industrial tasks more efficient. The system uses implemented methods to process data from fisheye camera data and depth sensor data, to check the quality of the throws. LÄS MER
