  1. 31. Tomographic studies of the 21-cm signal during reionization : Going beyond the power spectrum

    Författare :Sambit K. Giri; Garrelt Mellema; Benoît Semelin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reionization; non-gaussianity; first stars; image processing; Astronomy; astronomi;

    Sammanfattning : The formation of the first luminous sources in the Universe, such as the first generation of stars and accreting black holes, led to the ionization of hydrogen gas present in the intergalactic medium (IGM). This period in which the Universe transitioned from a cold and neutral state to a predominantly hot and ionized state is known as the Epoch of Reionization (EoR). LÄS MER

  3. 32. Segmenting and Tagging Text with Neural Networks

    Författare :Yan Shao; Joakim Nivre; Jörg Tiedemann; Christian Hardmeier; Yue Zhang; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neural networks; sequence labelling; multilinguality; word segmentation; sentence segmentation; morpheme segmentation; transliteration; joint word segmentation and POS tagging;

    Sammanfattning : Segmentation and tagging of text are important preprocessing steps for higher-level natural language processing tasks. In this thesis, we apply a sequence labelling framework based on neural networks to various segmentation and tagging tasks, including sentence segmentation, word segmentation, morpheme segmentation, joint word segmentation and part-of-speech tagging, and named entity transliteration.

  4. 33. Invariancy Methods for Points, Curves and Surfaces in Computational Vision

    Författare :Karl Åström; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; curved surface; space curve; planar curve; laser guided vehicles; AGV; autonomous guided vehicles; recognition; reconstruction; image sequence; multiple view geometry; affine; invariant; projective; Mathematics; Matematik;

    Sammanfattning : Many issues in computational vision can be understood from the interplay between camera geometry and the structure of images and objects. Typically, the image structure is available and the goal is to reconstruct object structure and camera geometry. This is often difficult due to the complex interdependence between these three entities. LÄS MER

  5. 34. Mot lärdomens topp : Svenska humanisters och samhällsvetares ursprung, utbildning och yrkesbana under 1900-talets första hälft

    Författare :Tobias Dalberg; Mikael Börjesson; Donald Broady; Martin Gustavsson; Per Wisselgren; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; academic careers; trajectories; academic field; disciplines; institutionalisation; humanities; social sciences; prosopography; geometric data analysis; sequence analysis; Sweden; 20th century; sociology of education; Utbildningssociologi; Sociology of Education;

    Sammanfattning : This dissertation employs Pierre Bourdieu’s concepts of capital and field alongside Robert K. Merton’s notion of accumulation of advantage to study how different types of assets affect career trajectories in the humanities and social sciences. LÄS MER

  7. 35. Engineering membrane proteins for production and topology

    Författare :Stephen Toddo; Daniel Daley; Roslyn Bill; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane protein; Over-expression; Protein production; Codon optimization; Escherichia coli; AraH; NarK; mRNA secondary structure; coding sequence; ribosome binding site; RBS; topology; split-GFP; Biochemistry; biokemi;

    Sammanfattning : The genomes of diverse organisms are predicted to contain 20 – 30% membrane protein encoding genes and more than half of all therapeutics target membrane proteins. However, only 2% of crystal structures deposited in the protein data bank represent integral membrane proteins. LÄS MER
