  1. 1. Multidimensional MRI of Cardiac Motion : Acquisition, Reconstruction and Visualization

    Författare :Andreas Sigfridsson; Hans Knutsson; Stefan Skare; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MRI; cardiac; motion; reconstruction; Image analysis; Bildanalys;

    Sammanfattning : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all benefit from improved methods of measuring the dynamics of the heart. LÄS MER

  3. 2. Långhus i Gene : teori och praktik i rekonstruktion

    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Reconstruction; longhouse; Early Iron Age; Central Norrland; furnishing; room functions; fire; seat of honour; Christianisation; Icelandic sagas; Icelandic construction techniques; Arkeologi; Archaeology subjects; Arkeologiämnen; Archaeology; arkeologi;

    Sammanfattning : Under åren 1977–89 bedrev arkeologiska institutionen vid Umeå universitet en forskningsundersökning av en boplats från äldre järnålder på Genesmon i Själevad socken, norra Ångermanland. Under åren 1991–99 rekonstruerades delar av gården i Gene fornby, ett hundratal meter därifrån. LÄS MER

  4. 3. Finger Joint Reconstruction with Rib Perichondrium

    Författare :Daniel Muder; Torbjörn Vedung; Nils Hailer; Ola Nilsson; Simon Farnebo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; finger joint; reconstruction; cartilage; transplantation; osteoarthritis; Orthopaedics; Ortopedi;

    Sammanfattning : Difficulties in repairing and reconstructing articular cartilage damaged by trauma or disease remain unsolved and are one of the major challenges confronting orthopedic and hand surgeons in their clinical work. Relevant research has not adequately described the long-term clinical results, nor has it made a direct comparison to implant surgery after finger joint reconstruction with rib perichondrium.

  5. 4. Föreställningar om det förflutna. Arkeologi och rekonstruktion

    Författare :Bodil Petersson; Arkeologi; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; history of archaeology; museology; regional identity; political use; production of knowledge; re-enactment; living history; experiment; reconstruction; popularization; Arkeologi; arkeologi; Archaeology;

    Sammanfattning : The purpose of this dissertation is to discuss full-scale historical reconstruction in Denmark, Norway and Sweden. In recent years we have seen an accelerating interest among the public to visit reconstructed places with reference to ancient times. Reconstructions from the Stone Age to the Middle Ages are discussed. LÄS MER

  7. 5. Algebraic Reconstruction Methods

    Författare :Touraj Nikazad; Tommy Elfving; Constantin Popa; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iterative methods; image reconstruction; ART; Cimmino; Kaczmarz; Landweber; sequential iteration; simultaneous iteration; block iteration; semi-convergence; relaxation parameters; stopping rules; discrepancy principle; Numerical analysis; Numerisk analys;

    Sammanfattning : Ill-posed sets of linear equations typically arise when discretizing certain types of integral transforms. A well known example is image reconstruction, which can be modeled using the Radon transform. After expanding the solution into a finite series of basis functions a large, sparse and ill-conditioned linear system occurs. LÄS MER
