  1. 1. Active and Physics-Based Human Pose Reconstruction

    Författare :Erik Gärtner; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer vision; human pose estimation; reinforcement learning; physics-based human pose estimation; active learning;

    Sammanfattning : Perceiving humans is an important and complex problem within computervision. Its significance is derived from its numerous applications, suchas human-robot interaction, virtual reality, markerless motion capture,and human tracking for autonomous driving. The difficulty lies in thevariability in human appearance, physique, and plausible body poses. LÄS MER

  3. 2. Physics-based Modelling for Aircraft Noise and Emission Predictions

    Författare :Evangelia Maria Thoma; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measurements; trajectories.; emissions; interdependencies; FDR; turbofan engine; aircraft noise; physics-based modelling;

    Sammanfattning : Starting from semi-empirical noise source models for the aircraft and 4D trajectory computations, this work focuses on the environmental assessment of scenario studies regarding technology evaluation and procedural planning. Extensive work was performed on improving and validating the existing tools. LÄS MER

  4. 3. Realistic Package Opening Simulations : An Experimental Mechanics and Physics Based Approach

    Författare :Eskil Andreasson; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer; aluminium foil; semi-crystalline; progressive damage; Abaqus;

    Sammanfattning : A finite element modeling strategy targeting package opening simulations is the final goal with this work. The developed simulation model will be used to proactively predict the opening compatibility early in the development process of a new opening device and/or a new packaging material. LÄS MER

  5. 4. Lithium ion Battery Aging: Battery Lifetime Testing and Physics-based Modeling for Electric Vehicle Applications

    Författare :Evelina Wikner; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physics-based modeling; Electric Vehicle EV ; Battery lifetime tests; Hybrid Electric Vehicle HEV ; Plug-in Hybrid Electric Vehicle PHEV ; Calendar aging;

    Sammanfattning : Electrification of vehicles is one solution in reducing emissions from the transport sector, and in particular to limit tail-pipe emissions in cities. In order to make the electrification successful and cost effective, there is a high demand for longer drive range and longer battery lifetime. LÄS MER

  7. 5. Hybrid digital twins: A co-creation of data science and physics

    Författare :Antonio Galvez; Diego Galar; Uday Kumar; Dammika Seneviratne; Dimitrios Kyritsis; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid modelling; physics-based model; data-driven model; HVAC system; Railway; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Safety is more important than reliability or efficiency in railway, aerospace, oil & gas, and chemical industries. Regulations are very restrictive in sectors where safety is paramount. LÄS MER
