    Sammanfattning : Medical imaging continues to permeate the practice of medicine, but automated yet accurate segmentation and labeling of anatomical structures continues to be a major obstacle to computerized medical image analysis (MIA). Deformable models, with its profound roots in estimation theory, optimization, and physics-based dynamical systems, represent a powerful approach to the general problem of medical image segmentation.

  4. 3. Surface Plasmon Resonance : Sensitivity and Resolution

    Författare :Knut Johansen; Günter Gauglitz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Surface plasmon resonance (SPR) is a frequently used technique for detection of biomolecular interactions at surfaces. The SPR phenomenon emanates from an electromagnetic surface wave that is exited by a light source. LÄS MER

  5. 4. The Shape of Strangeness: Transverse Spherocity and Underlying Event studies of φ and its relation to Ξ in √s = 13 TeV pp collisions

    Författare :Adrian Nassirpour; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; ALICE; Quark-Gluon Plasma; small systems; pp collisions; underlying event; event-shape engineering; transverse activity; strangeness enhancement; resonance production; Fysicumarkivet A:2022:Nassirpour;

    Sammanfattning : Through ultrarelativistic particle collisions at the LHC, it is possible to deconfine quarks and gluons. This deconfinement gives rise to a strongly interacting medium, referred to as the Quark-Gluon Plasma (QGP). LÄS MER

  7. 5. Hydrodynamic Modelling for a Point Absorbing Wave Energy Converter

    Författare :Jens Engström; Jan Isberg; Mats Leijon; Antonio Sarmento; Uppsala universitet; []
