  1. 11. Shock absorber dynamics : A parameter study of damper physical quantitiesand their effect on automobile comfort and control

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :David Stridfeldt; Jonsson Gustav; [2023]
    Nyckelord :Shock absorbers; dampers; parameter study; valve dynamics; comfort; control; Stötdämpare; dämpare; parameterstudie; ventildynamik; komfort; kontroll;

    Sammanfattning :   Damper performance is most commonly characterized by the damper’s forcevelocity behaviour. Different damper layouts and valving methods for creating oil flow constrictions bring different physical properties, outside of this conventional measure. LÄS MER

  3. 12. Efficient Traffic Monitoring in IoT Networks for Attack Detection at the Edge

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Engla Jansson; [2023]
    Nyckelord :;

    Sammanfattning : The Internet of Things has rapidly expanded over the years, and with this comes significant security risks, with attacks increasing at an alarming rate. A way to detect attacks in the network is by having each device send traffic monitoring information to an edge device that can investigate if any devices have been exploited. LÄS MER

  4. 13. A Hierarchical Tucker Solver for the Vlasov-Maxwell System

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Oskar Tegby; [2023]
    Nyckelord :;

    Sammanfattning : The Vlasov-Maxwell equations is a common model to describe the behavior of a plasma, but come at the cost of their dimensionality since both spatial and veloocity data is stored in three dimensions. This causes a significant obstacle to be able solve them numerically since the size of the data is N^6, which yields a data size of 8. LÄS MER

  5. 14. Correlation between Surface and Tumour Motion in Lung Cancer - including Deep Learning Perspectives

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Caisa Kjellström; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose: The purpose of this master thesis was to retrospectively investigate correlation between surface and tumour motion in lung cancer patients, alongside deep learning applications of the results. Additional correlations such as age, tumour volume and anatomical placement of the tumour were also investigated. LÄS MER

  7. 15. Robust visual SLAM with compressed image data : A study of ORB-SLAM3 performance under extreme image compression

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

    Författare :Guangzhi Wang; [2023]
    Nyckelord :ORB-SLAM3; compression; image feature; localization accuracy; internal parameter; hybrid compressing; brightness enhancement; ORB-SLAM3; kompression; bildfunktion; lokaliseringsnoggrannhet; intern parameter; hybridkomprimering; ljusstyrkeförstärkning;

    Sammanfattning : Offloading SLAM to the edge/cloud is now becoming an attractive option to greatly decrease device energy usage. The new SLAM solution involves compressing image data on the device before transmission, allowing a further decrease in the network bandwidth when performing SLAM at the edge/cloud. LÄS MER
