  1. 36. Modeling Organizational Dynamics : Distributions, Networks, Sequences and Mechanisms

    Författare :Hernan Mondani; Fredrik Liljeros; Rickard Sandell; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; organizational dynamics; social organizing; organizational change; modeling; organizational growth; process stability; labor flow network; employment trajectories; heavy-tailed distributions; complex network analysis; sequence analysis; agent-based modeling; sociophysics; Sociology; sociologi;

    Sammanfattning : The study of how social organizations work, change and develop is central to sociology and to our understanding of the social world and its transformations. At the same time, the underlying principles of organizational dynamics are extremely difficult to investigate. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; image registering; multi-slice; slice profile; ferrous sulphate; polyacrylamide; 3D volume acquisition; RF field; B1 field; relaxation time; T1; T2; spin-echo; multi-spin-echo; stochastic noise; nonuniformity; SNR; radiologi; tomografi; medicinsk instrumentering; Radiopharmaceutical technology; Radiofarmaceutisk teknik; Physics; Fysik;

    Sammanfattning : Gel dosimetry is a new dosimetry method applied in radiation therapy. Gel dosimeters consist of a radiation sensitive gel, which can integrate absorbed doses from several radiation sources or beams. The dose to the gel can be evaluated by magnetic resonance imaging (MRI), a procedure that is the focus of the present thesis. LÄS MER

  4. 38. Sequence based identification of genetic variation associated with intellectual disability

    Författare :Jin Zhao; Lars Feuk; Anna Lindstrand; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : Intellectual disability (ID) is a common neurodevelopmental condition, often caused by genetic defects. De novo variation (DNV) is an important cause of ID, especially in severe or syndromic forms of the disorder. Next generation sequencing has been a successful application for finding pathogenic variation in ID patients. LÄS MER

  5. 39. Geometry and Critical Configurations of Multiple Views

    Författare :Fredrik Kahl; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; algebra; algebraic geometry; field theory; Number Theory; Matematik; Mathematics; reconstruction; image sequence; absolute conic; critical motions; critical surfaces; perspective projection; affine geometry; Euclidean geometry; multiple view geometry; projective geometry; group theory; Talteori; fältteori; algebraisk geometri; gruppteori; Mathematical logic; set theory; combinatories; Matematisk logik; mängdlära; kombinatorik;

    Sammanfattning : This thesis is concerned with one of the core problems in computer vision, namely to reconstruct a real world scene from several images of it. The interplay between the geometry of the scene, the cameras and the images is analyzed. LÄS MER

  7. 40. Stratified algebras and classification of tilting modules

    Författare :Elin Persson Westin; Volodymyr Mazorchuk; Aslak Buan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Representation theory; Generalized tilting module; Exceptional sequence; Quasi-hereditary algebra; Standardly stratified algebra; Essential order; Category O; S-subcategory; Projective dimension; Finitistic dimension; Mathematics; Matematik;

    Sammanfattning : This thesis contains three papers in representation theory of algebras. It mainly studies two types of algebras; quasi-hereditary algebras and standardly stratified algebras. LÄS MER
