  1. 6. 3D-Reconstruction of the Common Murre

    University essay from Linköpings universitet/Datorseende

    Author : Johannes Hägerlind; [2023]
    Keywords : pose estimation; shape estimation; 3D reconstruction; articulated mesh; bird; common murre;

    Abstract : Automatic 3D reconstruction of birds can aid researchers in studying their behavior. Recently there has been an attempt to reconstruct a variety of birds from single-view images. However, the common murre's appearance is different from the birds that have been studied. Moreover, recent studies have focused on side views. READ MORE

  3. 7. Real-time Soft Body Simulation using Extended Position-Based Dynamics and Tetrahedral Deformation

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : William Kamnert; [2023]
    Keywords : Physically based animation; Soft body deformation; Volumetric models; GPU parallel computing;

    Abstract : Background. Several methods have been used to simulate soft body deformation, such as mass-spring systems and position-based dynamics. This has been done using tetrahedral mesh models for preservation of shape and volume. READ MORE

  5. 9. Multi-Scale Topology Optimization of Lattice Structures Using Machine Learning

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Julia Ibstedt; [2023]
    Keywords : Topology optimization; Multi-scale topology optimization; Machine learning; Gaussian process; Homogenization; Inverse homogenization; Anisotropic materials; Symmetry groups; Material property space; Topologioptimering; Flerskalig topologioptimering; Maskininlärning; Gaussian process; Homogenisering; Anisotropa material; Symmetrigrupper; Materialegenskapsrymd;

    Abstract : This thesis explores using multi-scale topology optimization (TO) by utilizing inverse homogenization to automate the adjustment of each unit-cell's geometry and placement in a lattice structure within a pressure vessel (the design domain) to achieve desired structural properties. The aim is to find the optimal material distribution within the design domain as well as desired material properties at each discretized element and use machine learning (ML) to map microstructures with corresponding prescribed effective properties.

  6. 10. Adjoint optimization of a liquid-cooled heat sink

    University essay from KTH/Teknisk mekanik

    Author : Roven Pinto; [2023]
    Keywords : Adjoint method; topology optimization; porosity; OpenFOAM;

    Abstract : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. READ MORE
