  1. 1. Blow-ups and normal bundles in derived algebraic geometry and beyond

    Författare :Jeroen Hekking; David Rydh; Marco Robalo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; derived algebraic geometry; blow-ups; normal bundles; Weil restrictions; Matematik; Mathematics;

    Sammanfattning : The main part of this thesis, Part II, consists of four papers. A summary and background is provided in Part I.Paper A introduces blow-ups of derived schemes in arbitrary centers, which is a generalization of the quasi-smooth case from [KR19]. LÄS MER

  3. 2. Reverse structural biology: Cellular processes uncovered by electron microscopy

    Författare :Jacob Croft; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; flagella; nuclear envelope budding; TAILS; cryo-EM; microtubule inner protein;

    Sammanfattning : This thesis contains two projects, both using electron microscopy as the primary technique. In the first project, nuclear envelope budding (NEB) is investigated as an alternate method of transport across the nuclear envelope. LÄS MER

  4. 3. Modeling of the wet-out process in composites manufacturing

    Författare :Da Wu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process modeling; liquid composite molding; fiber preform deformation; free surface flow; porous media theory;

    Sammanfattning : The fiber reinforced polymer composites (FRPCs) are carving out a niche amid the keen market competition to replace the other material counterparts, e.g., metals. Due to the low weight and corrosion resistance, the FRPCs are wildly utilized from aviation to automobile industries; both in the sectors of civilian and defense. LÄS MER

  5. 4. MUSCLE TONE IMBALANCE IN HUMAN UPPER EXTREMITY An experimental study of muscle adaptation to altered tension

    Författare :Fredrik Einarsson; Göteborgs universitet; []
    Nyckelord :muscle biopsy; freeze storage; upper extremity; shoulder; human muscle; sarcomere; stress-strain relationship; stress relaxation; stiffness; elasticity; mechanical testing; morphology; spasticity; obstetric brachial plexus palsy; rotator cuff tear; tendon transfer;

    Sammanfattning : Aim: The aim of this thesis was to improve outcome after tendon transfer and rotator cuff surgery by investigating the impact on response to passive mechanical testing and change in structural characteristics associated with longstanding changes in the tension of skeletal muscle in the human upper extremities in vivo. Patients and methods: The investigational method was in vitro assessment of human upper extremity muscles. LÄS MER

  7. 5. Manifold learning and representations for image analysis and visualization

    Författare :Anders Brun; Hans Knutsson; Magnus Herberthson; Carl-Fredrik Westin; Reiner Lenz; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; manifold learning; image analysis; signal processing; diffusion tensor mri; Medical informatics; Medicinsk informatik;

    Sammanfattning : We present a novel method for manifold learning, i.e. identification of the low-dimensional manifold-like structure present in a set of data points in a possibly high-dimensional space. The main idea is derived from the concept of Riemannian normal coordinates. LÄS MER
