  1. 1. Advanced methods for the calibration of optical tweezers

    Författare :Laura Pérez García; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optiska pincetter; kalibrera; probabilistiska metoder; bayesiansk inferens; styvhet; diffusionskoefficient;

    Sammanfattning : Optiska pincetter har sedan Arthur Ashkin och hans kollegors uppfinning på 1980-talet möjliggjort noggrann manipulation av mikroskopiska partiklar. Denna teknik har haft betydande inverkan inom flera områden, inklusive biologi, fysik, nanoteknik, spektroskopi, mjuka material och nanotermodynamik. LÄS MER

  3. 2. Scalable and Efficient Probabilistic Topic Model Inference for Textual Data

    Författare :Måns Magnusson; Mattias Villani; Marco Kuhlmann; Jordan Boyd-Graber; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Text analysis; Bayesian inference; Markov chain Monte Carlo; topic models; Textanalys; Bayesiansk inferens; Markov chain Monte Carlo; temamodeller;

    Sammanfattning : Probabilistic topic models have proven to be an extremely versatile class of mixed-membership models for discovering the thematic structure of text collections. There are many possible applications, covering a broad range of areas of study: technology, natural science, social science and the humanities. LÄS MER

  4. 3. Bayesian Models for Spatiotemporal Data from Transportation Networks

    Författare :Héctor Rodriguez Déniz; Mattias Villani; Augusto Voltes-Dorta; Yusak Susilo; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bayesian statistics; Transportation networks; Spatiotemporal data; Machine learning; Bayesiansk statistik; Transportnätverk; Spatiotemporal data; Maskininlärning;

    Sammanfattning : Urbanization has caused a historical transformation at a global scale, and humanity is moving towards a fully connected society where cities will concentrate population, infrastructure and economic activity. A key element in the cities’ infrastructure is the transportation system, as it facilitates the mobility of people and goods. LÄS MER

  5. 4. Variational methods for phylogeny and single-cell genomics

    Författare :Hazal Koptagel; Jens Lagergren; Alexandre Bouchard-Côté; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Variational inference; single-cell DNA sequencing; cell lineage tree; Bayesian phylogenetic tree inference; Variationsinferens; encellig DNA-sekvensering; cellhärkomstträd; Bayesiansk fylogenetisk trädinferens; Varyasyonel çıkarım; tek hücre DNA dizilimi; hücre soy ağacı; Bayesçi filogenetik ağaç çıkarımı; Datalogi; Computer Science;

    Sammanfattning : The investigation of the evolutionary history of organisms, both at the cellular level and at the species level, is a relevant research topic in computational biology. These investigations lead to a deeper understanding of developmental history, cancer progression, the genetic similarity of species, and more. LÄS MER

  7. 5. Bayesian Inference for Microwave Diagnostics at Joint European Torus

    Författare :Stefan Schmuck; Per Brunsell; Thomas Jonsson; Jakob Svensson; Laurie Porte; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ECE; Bayesian; Fourier transform; spectroscopy; joint inference; length-scale; Gaussian process; microwave diagnostic; JET; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The major goal of this thesis is to perform Bayesian inference jointly for electron kinetic profiles, a toroidal magnetic field correction, diagnostic sensitivities, and wall reflection properties given noisy measurements of four microwave diagnostics at the tokamak JET. Besides the measurements, this kind of inference considers prior knowledge, like profile length-scales, to update objectively the information about the physics parameters. LÄS MER
