  1. 16. Respiratory Motion Correction in PET Imaging: Comparative Analysis of External Device and Data-driven Gating Approaches

    Master-uppsats, KTH/Fysik

    Författare :Nina Lindström Söraas; [2023]
    Nyckelord :PET CT; Tomographic reconstruction; Respiratory gating techniques; Image registration; Motion correction; PET CT; Tomografisk rekonstruktion; Gating tekniker; Bildregistrering; Rörelsekorrigering;

    Sammanfattning : Positron Emission Tomography (PET) is pivotal in medical imaging but is prone to artifactsfrom physiological movements, notably respiration. These motion artifacts both degradeimage quality and compromise precise attenuation correction. LÄS MER

  3. 17. Solving the Gleason Problem using Partition of Unity

    Kandidat-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Amalia Adlerteg; [2023]
    Nyckelord :Gleason Problem; Partition of Unity;

    Sammanfattning : The Gleason problem has been proven to be a complicated issue to tackle. In this thesiswe will conclude that a domain, Ω ⊂ R𝑛, has Gleason 𝑅-property at any point 𝑝∈ Ω, where 𝑅(Ω) ⊂ 𝐶∞(Ω) is the ring of functions that are real analytic in 𝑝. First, we investigate function spaces and give them fitting norms. LÄS MER

  4. 18. Highly Available Task Scheduling in Distinctly Branched Directed Acyclic Graphs

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

    Författare :Patrik Zhong; [2023]
    Nyckelord :Distributed Scheduling; Fault-tolerance; Graph Partitioning; Task Graphs; Dask; Dask Distributed; Data Processing; Distribuerad Schemaläggning; Feltolerans; Grafpartitionering; Uppgiftsgrafer; Dask; Dask Distributed; Dataprocessering;

    Sammanfattning : Big data processing frameworks utilizing distributed frameworks to parallelize the computing of datasets have become a staple part of the data engineering and data science pipelines. One of the more known frameworks is Dask, a widely utilized distributed framework used for parallelizing data processing jobs. LÄS MER

    Kandidat-uppsats, Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Albin Jaldevik; [2022]
    Nyckelord :Discrete mathematics; Order theory; Combinatorics; Partially ordered set; Poset; Linear extension; Topological sorting; Probability; Partition; Young diagram;

    Sammanfattning : Let be a finite poset (partially ordered set) with cardinality . A linear extension of is an order-preserving bijection : , that is, if in then . We define the poset probability as the proportion of linear extensions where . We are primarily interested in for incomparable elements . LÄS MER
