  1. 1. Geometry of high dimensional Gaussian data

    Kandidat-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Olof Samuel Mossberg; [2024]
    Nyckelord :HDLSS; high dimensional data; stochastic boundedness; asymptotic orthogonality; geometry; multivariate normal distribution; HDLSS; högdimensionell data; stokastisk begränsning; asymptotisk ortogonalitet; geometri; multivariat normalfördelning;

    Sammanfattning : Collected data may simultaneously be of low sample size and high dimension. Such data exhibit some geometric regularities consisting of a single observation being a rotation on a sphere, and a pair of observations being orthogonal. This thesis investigates these geometric properties in some detail. LÄS MER

  3. 2. Itô Diffusions on Level Sets

    Master-uppsats, Uppsala universitet/Analys och partiella differentialekvationer; Uppsala universitet/Statistik, AI och data science

    Författare :Coën Olofsson; [2023]
    Nyckelord :Itô diffusions; level sets; stochastic differential geometry; numerical schemes;

    Sammanfattning : Itô diffusions that move on level sets of functions in Rn, which we have called level processes, are an overlooked variant of the classical Itô processes. These processes find themselves nestled between the study of regular Itô diffusions in Rn and diffusions which are bound to smooth manifolds. LÄS MER

  4. 3. Stochastic Geometry and Mosaic Models with Applications

    Master-uppsats, Uppsala universitet/Sannolikhetsteori och kombinatorik

    Författare :Albert Nilsson; [2023]
    Nyckelord :stochastic geometry; random mosaics; random tessellations;

    Sammanfattning : In this thesis, we consider stationary random mosaics with a focus on the Poisson-Voronoi mosaic and the Poisson-Delaunay mosaic. We consider properties of stationary random mosaics in R2, such as mean value results of the typical cell. LÄS MER

  5. 4. Analyzing V2V signal models in simulated 3D geometry-based stochastic channels

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Hussam Mohamed; Darshan Chawan; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Vehicle to everything (V2x) communication is one of the most researched topics today. The main goal behind this new emerging technology is road safety along with traffic and energy efficiency. Vehicular communications can further be sub-divided into certain types. LÄS MER

  7. 5. Matched Filters for Direct-Detection LiDAR in Non-Perpendicular Measurement Scenes

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Simon Ranefjärd; [2019]
    Nyckelord :;

    Sammanfattning : The ongoing development of Advanced Driver Assistance Systems (ADAS) and autonomous vehicles pushes the requirements of accurate measurements from several on-board sensors, one of which being the Light Detection And Ranging (LiDAR). The performance of the LiDAR measurements relies partially on the reflectivity of the target, the level of background noise and the angle of incidence to the measurement scene. LÄS MER
