  1. 1. Visualization of Space Debris using Orbital Representation and Volume Rendering

    Magister-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Författare :Jonathan Fransson; Elon Olsson; [2019]
    Nyckelord :;

    Sammanfattning : This report covers a master’s thesis project done at the University Of Utah for theOpenSpace project. OpenSpace is a open-source astronomy visualization software and thethesis focus was to visualize the ever-increasing number of man-made space debris. Twodifferent visualization methods have been used in this thesis. LÄS MER

  4. 3. Reconstruction of trees from 3D point clouds

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Martin Stålberg; [2017]
    Nyckelord :Bayes; Bayesian inference; point cloud; pointcloud; 3D; tree; trees; reconstruction; Matlab; Povray; Arbaro; model; LIDAR; Hough transform; cylinder; geometry; heuristic; Australia; Australian Centre for Field Robotics; spherical grid; icosahedron; likelihood; intersection; artificial data; color encoded; depth map; coordinate map; ray tracing;

    Sammanfattning : The geometrical structure of a tree can consist of thousands, even millions, of branches, twigs and leaves in complex arrangements. The structure contains a lot of useful information and can be used for example to assess a tree's health or calculate parameters such as total wood volume or branch size distribution. LÄS MER

  5. 4. Estimating area of vector polygons on spherical and ellipsoidal earth models with application in estimating regional carbon flows

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Huiting Huang; [2017]
    Nyckelord :spherical ellipsoidal earth model; regional carbon flows; map projection; area of a polygon; atmospheric inversions; Earth and Environmental Sciences;

    Sammanfattning : Estimating area of polygons on the Earth’s surface is required in many fields in earth science. In the field of carbon modelling, one application of estimating polygons’ area is to estimate carbon flows for regions. LÄS MER

  7. 5. Suspensions with small, spherical particles

    Kandidat-uppsats, KTH/Numerisk analys, NA

    Författare :Samuel Zackrisson; [2015]
    Nyckelord :;

    Sammanfattning : Feasibly computable analytic solutions for systems of many particles in fluid dynamics and electrostatics are few and far-between. Simulations and numerical approximations are essential to studying these systems. This is commonly done without directly calculating the interacting field between particles. LÄS MER
