  1. 1. Simuleringsdriven inferens av stokastiska dynamiska system

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Alfred Andersson; Vilgot Jansson; Noah Trädgårdh; Jacob Welander; Victor Wellsmo; [2023-11-28]
    Nyckelord :;

    Sammanfattning : Stokastiska modeller, som ger tillförlitlig och användbar information om ett systems beteende, består ofta av stokastiska differentialekvationer (SDE) vars likelihoodfunktion inte är analytiskt tillgänglig. Mer traditionella Markov Chain Monte Carlo-metoder (MCMC) samt relativt nyligen utvecklade likelihood-fria Approximate Bayesian Computation-metoder (ABC) utgör populära angrepssätt för att utföra inferens på dessa typer av problem.

  3. 2. The effect of autocorrelation when performing theapproximated permutation test

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Amerik Schouten; Linus Thor; [2023]
    Nyckelord :exchangeability assumption; Monte Carlo; temporal autocorrelation; type I error; simulation; re-sampling methods;

    Sammanfattning : In meteorology, permutation tests are a commonly recommended tool because standard paramet-ric methods of inference often is insufficient when analysing weather. Therefore other methodswith less stringent assumptions like permutation testing is used. LÄS MER

  4. 3. A Novel Method for Finding Overlap Depth : Development of ArtiaX, a ChimeraX plugin

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

    Författare :Gunnar Arctaedius; [2023]
    Nyckelord :Cryo-electron tomography; image processing; surface visualization; overlap measurement; normal projection method; Kryoelektrontomografi; bildbehandling; ytvisualisering; överlapsmätning; normalprojektionsmetoden;

    Sammanfattning : Visualization and image filtering are important parts of cryo-electron tomography analysis. ArtiaX, a plugin developed for UCSF ChimeraX, has been extended to improve the functionality of these two parts. For the visualization, a method of moving 3D surfaces to remove overlap between them has been developed and implemented. LÄS MER

  5. 4. AI and real-time Strategy Games

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Juan Pablo Botello Deras; [2023]
    Nyckelord :;

    Sammanfattning : As artificial intelligence continues to progress, applications hope to have AI perform tasks as good, if not better, than a human. A good way to test theoretical applications is through games, simple to complex. LÄS MER

  7. 5. Neutron Veto Inefficiency Studies with FLUKA for the LDMX Hadronic Calorimeter

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Jaida Raffelsberger; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter".
