  1. 1. Jämförande analys av frågor för enskilda och flera geometrityper för hämtning av geospatiala data i MySQL och MongoDB : Bedömning av frågeprestanda för platsbaserad information i MySQL och MongoDB

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :William Larsson; [2023]
    Nyckelord :MongoDB; MySQL; geospatial data; single-geometry types; multiple-geometry types;

    Sammanfattning : The use of databases for managing spatial data is widespread due to the efficiency of traditional SQL databases like Azure SQL. However, the exponential growth of data from sources like social media has led to the popularity of NoSQL databases such as MongoDB that handle large volumes of data effectively. LÄS MER

  3. 2. Optimizing Realistic 3D Facial Models for VR Avatars through Mesh Simplification

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

    Författare :Beiqian Liu; [2023]
    Nyckelord :Mesh Simplification; Virtual Reality; Realistic Avatars; 3D Face Reconstruction;

    Sammanfattning : The use of realistic 3D avatars in Virtual Reality (VR) has gained significant traction in applications such as telecommunication and gaming, offering immersive experiences and face-to-face interactions. However, standalone VR devices often face limitations in computational resources and real-time rendering requirements, necessitating the optimization of 3D models through mesh simplification to enhance performance and ensure a smooth user experience.

  4. 3. A geometric approach to calculating the limit set of eigenvalues for banded Toeplitz matrices

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Teodor Bucht; [2023]
    Nyckelord :Toeplitz matrices; Banded Toeplitz matrices; Limit set; Eigenvalues; Mathematics and Statistics;

    Sammanfattning : This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. LÄS MER

  5. 4. Parallelization of boolean operations for CAD Software using WebGPU

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Max Helmrich; Linus Käll; [2023]
    Nyckelord :Parallelization; Web; Boolean Operations; WebGPU; CAD; GPU Acceleration;

    Sammanfattning : This project is about finding ways to improve performance of a Computer-Aided-Design (CAD) application running in the web browser. With the new Web API WebGPU, it is now possible to use the GPU to accelerate calculations for CAD applications in the web. LÄS MER

  7. 5. Adjoint Curves of Polycons

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Hilding Boij; [2023]
    Nyckelord :;

    Sammanfattning : In this thesis we are going to discuss polycons and their adjoint curves. We willdefine polycons as a type of polygon that allows for boundary curves of degree 2. LÄS MER
