  1. 1. Testing and analysis of composites with 3D woven reinforcement

    Författare :Tomas Ekermann; Malin Åkermo; Stefan Hallström; Lars Pilgaard Mikkelsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D weave; finite element; manufacturing; yarn path; weaving; failure criteria; mechanical testing; 3D väv; finita element; tillverkning; trådbanor; vävning; brottkriterier; mekanisk provning; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Composites with three-dimensional (3D) reinforcement have several benefits, compared to laminated composites. Their through-thickness reinforcement increase the out-of-plane properties significantly and could eliminate problems with delaminations. Also, these composites have proven to have great damage tolerance and energy absorption. LÄS MER

  5. 4. Reinforcement Learning for Active Visual Perception

    Författare :Aleksis Pirinen; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer vision; reinforcement learning; deep learning; active vision; object detection; human pose estimation; semantic segmentation;

    Sammanfattning : Visual perception refers to automatically recognizing, detecting, or otherwise sensing the content of an image, video or scene. The most common contemporary approach to tackle a visual perception task is by training a deep neural network on a pre-existing dataset which provides examples of task success and failure, respectively.
