  1. 26. Optimization-Based Geometry Correction Of Blood Flow CFD Simulations Using 4D-Flow Data

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fritiof Hegardt; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 4D-flow is a powerful tool capable of capturing 3-dimensional, time-resolved flow measurements of blood flow in the body. Their current use is limited by resolution and scan times. A proposed solution is to use Simulation Based Imaging (SBI). LÄS MER

  3. 27. Use of the JET pedestal database to assess the role of ion temperature and plasma rotation on the discrepancy between ideal peeling-ballooning model and experimental data

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

    Författare :Max Eichenberger; [2022]
    Nyckelord :Nuclear fusion; Joint European Torus JET ; H-mode; pedestal; Edge-localized-modes ELMs ; Peeling-Ballooning; relative shift; ion temperature; plasma rotation; Kärnfusion; JET Joint European Torus ; H-läge; piedestal; ELM Edge Localized­Modes ; peeling-ballooning; relativ förskjutning; jontemperatur; plasmarotation;

    Sammanfattning : Next-generation and present fusion devices such as the Joint European Torus (JET) aim for plasma operations in H-mode, a plasma regime with high confinement and low loss of energy and fuel that results from a barrier for heat and particle transport at the plasma edge, the pedestal. Due to steep gradients of the density, temperature and pressure profiles, the pedestal experiences instabilities called Edge-localized-modes (ELMs) which lead to large fluxes of heat and particles that might damage machine components.

  4. 28. Radar Detection Using Deep Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Ziliang Xiong; Leonardo Carrera; [2022]
    Nyckelord :Deep Learning; Autonomous Driving; Radar; Point Cloud; Technology and Engineering;

    Sammanfattning : This thesis aims to reproduce and improve a paper about dynamic road user detection on 2D bird's-eye-view radar point cloud in the context of autonomous driving. We choose RadarScenes, a recent large public dataset, to train and test deep neural networks. LÄS MER

  5. 29. Research and Application of 6D Pose Estimation for Mobile 3D Cameras

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

    Författare :Qian Ruichao; [2022]
    Nyckelord :6 Degree-of-Freedom DoF ; pose estimation; deep learning; Light Detection and Ranging LiDAR ; structure light; TrueDepth; 6 frihetsgrader DoF ; poseringsuppskattning; djupinlärning; ljusdetektion och avstånd LiDAR ; strukturljus; TrueDepth;

    Sammanfattning : This work addresses the deep-learning-based 6 Degree-of-Freedom (DoF) pose estimation utilizing 3D cameras on an iPhone 13 Pro. The task of pose estimation is to estimate the spatial rotation and translation of an object given its 2D or 3D images. LÄS MER

  7. 30. Mechanical properties of WE43 : Finding optimized process parameters using PBF-LB for enhanced properties of the magnesium alloy

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Fanny Saarela; Fanny Sandblad; [2022]
    Nyckelord :biomedical engineering; materials science; additive manufacturing; powder bed fusion laser beam; PBF-LB; magnesium; magnesium alloys; WE43; mechanical properties; scan strategy; layer rotation; build direction; build orientation;

    Sammanfattning : When skeletal fractures are too extensive for fixation with plates and screws, autografts are the most used technique for treating this. Within the biomedical field the interest in biodegradable implants made from additive manufacturing have increased. Magnesium alloys has also gained interest because of its favorable mechanical properties.. LÄS MER
