  1. 1. Development of an embedded system platform for signal analysis and processing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Philip Lind; [2023]
    Nyckelord :Digital signal processing; DSP; digital filter; FIR; IIR; Butterworth; Chebychev; windowed sinc; Digital signalbehandling; DSP; digitalt filter; FIR; IIR; Butterworth; Chebychev; sinc; fönstermetoder;

    Sammanfattning : Information is often stored and transmitted through electrical signals. This information may need refinement, which may be done by processing and altering the electrical signals, in which it is transmitted. When refining a signal, a frequency selective filter is often used. It can be implemented through digital signal processing (DSP). LÄS MER

  3. 2. Atmospheric Gravity Waves revisited with the EISCAT radar

    Master-uppsats, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen; Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Tatsuya Hirabayashi; [2023]
    Nyckelord :;

    Sammanfattning : It is known that AGWs strongly interact with Traveling Ionospheric Disturbancescalled TIDs (e.g. Kirchengast et al., 1996). LÄS MER

  4. 3. Preparations for photon external beam radiotherapy treatment planning of small animals

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Joanie Diha Guei; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. LÄS MER

  5. 4. Skeleton Tracking for Sports Using LiDAR Depth Camera

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Panagiotis Efstratiou; [2021]
    Nyckelord :Depth camera; Human pose estimation; Kinematics; Motion Capture; Skeletal tracking; Djupkamera; Uppskattning av mänsklig pose; Kinematik; Rörelseregistreringssystem; Skelettspårning;

    Sammanfattning : Skeletal tracking can be accomplished deploying human pose estimation strategies. Deep learning is shown to be the paramount approach in the realm where in collaboration with a ”light detection and ranging” depth camera the development of a markerless motion analysis software system seems to be feasible.

  7. 5. Extended and Unscented Kalman Filtering for Estimating Friction and Clamping Force in Threaded Fasteners

    Master-uppsats, Uppsala universitet/Signaler och system

    Författare :Mohammad Al-Barghouthi; [2021]
    Nyckelord :Estimation Theory; Extended Kalman Filter; EKF; Unscented Kalman Filter; UKF; Observability; Friction; Clamping Force; Tightening; Torque Controlled; Bolt; Threaded Fasteners;

    Sammanfattning : Threaded fasteners tend to break and loosen when exposed to cyclic loads or potent temperature variations. Additionally, if the joint is held tightly to the structure, distortion will occur under thermal expansion issues. LÄS MER
