  1. 1. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Emma Olofsson; [2023-06-22]
    Nyckelord :Assisted reproduction technologies Spermatozoa DNA fragmentation Density-gra- dient centrifugation Microfluidics ZyMōt Multi;

    Sammanfattning : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. LÄS MER

  3. 2. Exploration of Alternative Image Representation Using Signed Distance Functions

    Master-uppsats, Lunds universitet/Institutionen för designvetenskaper

    Författare :Jakub Olejnik; [2023]
    Nyckelord :computer graphics; SDF-based rendering; machine learning; Technology and Engineering;

    Sammanfattning : This project leverages the core concepts of differentiable rendering to find alternative representation of images using geometric primitives rendered with Signed Distance Functions. By utilising gradient-descent-based methods it is possible to find optimal parameters of rendered primitives to create high-quality reconstruction. LÄS MER

  4. 3. Signed Distance Field For Deformable Terrain Shovel Collision Detection

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Johannes Strid; [2023]
    Nyckelord :Signed Distance Fields; Collision Detection; Deformable Terrain;

    Sammanfattning : One commonly used representation of complex objects in physics-based simulations are triangle meshes. This representation utilizes a collection of triangles to approximate an object. An alternative representation is a Signed Distance Field (SDF). LÄS MER

  5. 4. Humans in the wild : NeRFs for Dynamic Scenes Modeling from In-the-Wild Monocular Videos with Humans

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

    Författare :Sanvito Alessandro; [2023]
    Nyckelord :Clothed Human Reconstruction; Neural Rendering; Neural Radiance Fields; Scene Reconstruction; Computer Vision; Clothed Human Reconstruction; Neural Rendering; Neural Radiance Fields; Scene Reconstruction; Computer Vision;

    Sammanfattning : Recent advancements in computer vision have led to the emergence of Neural Radiance Fields (NeRFs), a powerful tool for reconstructing photorealistic 3D scenes, even in dynamic settings. However, these methods struggle when dealing with human subjects, especially when the subject is partially obscured or not completely observable, resulting in inaccurate reconstructions of geometries and textures.

  7. 5. Effects of Design Space Discretization on Constraint Based Design Space Exploration

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Ludwig Karlsson; [2023]
    Nyckelord :Constraint programming; Design space exploration; Discretization; Multiresolutional analysis; Villkorsprogrammering; Designrymdsutforskning; Diskretisering; Multiupplösningsanalys;

    Sammanfattning : Design Space Exploration (DSE) is the exploration of a space of possible designs with the goal of finding some optimal design according to some constraints and criteria. Within embedded systems design, automated DSE in particular can allow the system designer to efficiently find good solutions in highly complex design spaces. LÄS MER
