  1. 1. The impact of snow loads on snow galleries : An initial evaluation of the snow galleries on the Iron Ore Line in Northern Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Karin Björnlinger; [2022]
    Keywords : Snow load; snow gallery; steel; FEM; railway; cobweb effect; utilizations grade; Snölast; snögalleri; stål; FEM; järnväg; spindelnätseffekten; utnyttjandegrad;

    Abstract : The snow galleries along the Iron ore railway line in northern Sweden have had major problems in recent years due to increasingly large snow loads. Despite great efforts reducing the loads by shoveling off the snow, several of the galleries have been damaged. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Qian Ruichao; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 3. Design of an In-situ cell, for hard X-ray spectroscopy of surfaces used in high-pressure and high-temperature experiments : Design av en In-situ cell för intensiv röntgenspektroskopi i högtryck- högtemperaturexperiment

    University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Author : David Zamora Torres; Felix Abeln; [2021]
    Keywords : In-situ cell; x-ray; XAS; x-ray absorption spectroscopy; XAFS; FEM; Finite element method; In-situ cell; x-ray; XAS; XAFS; FEM; Finita element metoden; röntgenspektroskopi;

    Abstract : This project analyzes how an in-situ cell can be developed to withstand high amounts of pressure and temperature of at least 100 bar and 500 °C. A theoretical prototype will be created as a product for Malmö University and other researchers to use or improve. READ MORE

  5. 4. Thermomechanical stress analysis of the main insulation system of traction electrical machines

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Dahman Ismail; Alexis Andrei; [2020]
    Keywords : finite element analysis; thermo-mechanical stress; heavy-duty vehicle; electrical machine; insulation system; coupled-temperature displacement analysis; finita element analys; termomekaniska spänningar; lastbilar; elektriska motorer; isolering; termisk kopplingsförbindelse;

    Abstract : More efficiency heavy-duty vehicles are developed with higher range, updated electronic and mechanical parts. The fuel efficiency and pollution of carbon dioxide need to be lower to achieve new EU regulations. The global population increases with an increased number of heavy-duty vehicles. This, in turn, increases the emission. READ MORE

  6. 5. Dynamic Soil-Structure Interactionof Soil-Steel Composite Bridges : A Frequency Domain Approach Using PML Elements and Model Updating

    University essay from KTH/Bro- och stålbyggnad
