  1. 1. Structural Analysis and Redesign of a L90 Front Axle Casing

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Erik Berra Widén; [2023]
    Nyckelord :FEM; Ansys Mechanical; Axle Casing; Volvo CE; Wheel Loader; Redesign;

    Sammanfattning : This thesis was commissioned by Volvo Construction Equipment (Volvo CE) to redesign the front axle casing of their L90 wheel loader to be more in line with their larger wheel loaders. The current L90 front axle casing consists of two parts bolted together in the middle. LÄS MER

  3. 2. Segmentation of x-ray images using deep learning trained on synthetic data

    Master-uppsats, KTH/Fysik

    Författare :Marcus Larsson; [2023]
    Nyckelord :Radiography; Deep Learning; Synthetic Data; Segmentation; Röntgen; Djupinlärning; Syntetisk Data; Segmentering;

    Sammanfattning : Radiograph examinations play a critical role in various applications such as the detection of bone pathologies and lung cancer, despite the challenge of false negatives. The integration of Artificial Intelligence (AI) holds promise in enhancing image quality and assisting radiologists in their diagnostic processes. LÄS MER

  4. 3. Development and evaluation of an inter-subject image registration method for body composition analysis for three slice CT images

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Hugo Dahlberg; [2022]
    Nyckelord :Medical imaging; Image registration; SCAPIS;

    Sammanfattning : Over 30 000 liver, abdomen, and thigh slices have been acquired by computed tomography for the SCAPIS and IGT study. To utilise the full potential of the large cohort and enable statistical pixel-wise body composition analysis and visualisation of associations with other biomarkers, a point-to-point correspondence between the scans is needed.

  5. 4. Diagnosing Tuberculosis - A critical review of palaeopathological literature on tuberculosis in human skeletal and mummified remains

    Master-uppsats, Lunds universitet/Historisk osteologi

    Författare :Lina Andersson; [2021]
    Nyckelord :Tuberculosis; critical review; methods; palaeopathology; Pott´s disease; ribs; History and Archaeology;

    Sammanfattning : To analyse tuberculosis both in present and historic times becomes very important in order to understand the magnitude of this disease. The presented information in this thesis was based on a quantitative analysis of skeletal traits and aDNA used to diagnose tuberculosis in skeletal material and mummified remains. LÄS MER

  7. 5. Noise Reduction of Scintillation Camera Images Using UNET: A Monte Carlo Simulation Approach

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Johanna Korpijärvi; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background The project aims to reduce the noise in planar 111-In projections with a machine learning model. Method Sixteen base phantoms were used to create 696 phantoms in XCAT. An anterior planar projection was simulated with 111-In and ten uptake curves for each phantom in SIMIND. LÄS MER
