  1. 6. Gyromätning i tunnelnät : Gyromätningens påverkan på kortare stomnät i tunnelmiljö

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Oskar Wängdahl; [2023]
    Nyckelord :Gyrotheodolite; Gyro surveys; Gyro measurements; Tunneling network; Geodetic control network; Truss network; Gyroteodolit; Gyromätning; Tunnelnät; Stomnät; fackverksnät;

    Sammanfattning : Geodetic measurements with a gyro theodolite are an important technique for establishing control networks in tunnelling projects. The observations are used as a separate control point outside the main network while checking the angle of the tunnels direction as it is difficult to connect the underground network to a superior network outside the tunnel.

  3. 7. 3D Estimation of Joints for Motion Analysis in Sports Medicine : A study examining the possibility for monocular 3D estimation to be used as motion analysis for applications within sports with the goal to prevent injury and improve sport specific motion

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Axel Persson; [2023]
    Nyckelord :;

    Sammanfattning : 3D joint estimation can be used to track bodies in areas such as entertainment, sports, biomedicine and surveillance to identify bodies from video streams and images. This is most commonly done with multi-view solutions but researchers are currently spending a large amount of resources into developing mono-view solutions. LÄS MER

  4. 8. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Jacob Lindahl; [2023]
    Nyckelord :LDMX; ANN; CNN; GNN; RNN; DM; Physics and Astronomy;

    Sammanfattning : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. LÄS MER

  5. 9. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Albin Lindvall; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

  7. 10. Automation of High-accuracy Marking Tasks at MAX IV using the Quadrupedal Robot Spot

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Sebastian Gulz-Haake; Nils Karlbrink Malmquist; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : When installing new research equipment at the synchrotron research laboratory MAX IV, a final positional accuracy of tens of microns is usually needed. To obtain that accuracy, initial reference points must be placed within 2 mm from the nominal target points in CAD, in a process referred to as bluelining. LÄS MER
