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

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

    Abstract : 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]. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Da Wu; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; process modeling; liquid composite molding; fiber preform deformation; free surface flow; porous media theory;

    Abstract : 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. READ MORE

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

    Author : Fredrik Einarsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
