  1. 1. Deep Learning-based Regularizers for Cone Beam Computed Tomography Reconstruction

    University essay from KTH/Matematisk statistik

    Author : Sabina Syed; Josefin Stenberg; [2023]
    Keywords : Adversarial Convex Regularization; Computer Vision; Cone Beam Computed Tomography; Convolutional Neural Networks; Deep Learning; Image Reconstruction; Adversarial Convex Regularization; Bildrekonstruktion; Datorseende; Djupinlärning; Faltningsnätverk; Volymtomografi;

    Abstract : Cone Beam Computed Tomography is a technology to visualize the 3D interior anatomy of a patient. It is important for image-guided radiation therapy in cancer treatment. During a scan, iterative methods are often used for the image reconstruction step. READ MORE

  3. 2. 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

  4. 3. Real-time refraction through multiple layers using image-space method with inline ray tracing

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

    Author : Daniel Parhizgar; [2021]
    Keywords : ;

    Abstract : Although modern hardware allows us to use ray tracing in real-time, ray traced refractions are still demanding due to its need to generate multiple rays recursively in order to fully refract through a multi-layered object. With the recent release of inline ray tracing, it is possible to traverse and register ray hits inside a fragment shader. READ MORE

  5. 4. Evaluating spreadability of metallic powders for powder bed fusion processes

    University essay from KTH/Materialvetenskap

    Author : Vignesh Hari; [2020]
    Keywords : Additive manufacturing; spreadability; flowability; Additiv tillverkning; spridbarhet; flytbarhet; mätetal;

    Abstract : Additive  manufacturing  technologies  are  widely  used  in  aerospace,  space,  and  turbine industries. Parts can be manufactured directly by selectively adding materials layer-by-layer. A key aspect that is critical to the quality of the final component being manufactured is the powder characteristics. READ MORE

  6. 5. Creating triangle strips from clustered point sets

    University essay from Akademin för teknik och miljö; Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : Peter Jenke; [2010]
    Keywords : surface reconstruction; triangle strip; convex layers; rotating calipers;

    Abstract : To create a digital model of the surface of some object from a setof points, representing positions on the surface of this object, requiresinformation about the relationship between the points. This informa-tion is not immediatly accessible. Thus, for creating such a model itis necessary to establish relationsships between the points of the set. READ MORE
