  1. 11. Optical shape measurements using temporal phase unwrapping

    Författare :Lars Kinell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : This doctoral thesis is devoted to optical shape measurements using an analysis scheme called temporal phase unwrapping. This scheme makes it possible to determine the absolute distance from a detector (usually a camera’s CCD-detector) to an object. Two different optical methods are considered for this 3-D sensing.

  3. 12. Modelling of laser-based powder bed fusion for bulk metallic glass formation

    Författare :Johan Lindwall; Andreas Lundbäck; Albert To; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : The work presented in this thesis aims to develop a modelling approach to predict crystalline phase evolution in bulk metallic glass during additive manufacturing with laser-based powder bed fusion (PBF-LB). Metallic glasses are non-crystalline metallic materials that generally possess exceptional properties because of its amorphous struc-ture. LÄS MER

  4. 13. Modelling and simulation of hot stamping

    Författare :Paul Åkerström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The growing effort to reduce vehicle weight and improve passive safety in the automotive industry has drastically increased the demand for ultra high strength steel components. There are several production technologies for such components. LÄS MER

  5. 14. Finger-Joints for Laminated Beams : Experimental and Numerical Studies of Mechanical Behaviour

    Författare :Erik Serrano; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Finger-joints; Laminated timber; Testing; Nonlinear fracture mechanics; Finite Elemente Method; Lamininating effect;

    Sammanfattning : The introduction of laminated timber, glulam being an example, allowed many of the disadvantages associated with solid wood to be overcome. The disadvantages in question are mainly those related to the size and shape limits of structural elements made of solid wood and to the large variability in such material properties of solid wood as strength and stiffness.

  7. 15. Linking Probability Theory and Quantum Mechanics, and a Novel Formulation of Quantization

    Författare :Fritiof Wallentin; Andrei Khrennikov; Kisil Vladimir; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum mechanics; contextuality; probabilistic interpretation; Born’s rule; frequentist interpretation; unitary representations; classical statistical mechanics; Koopman-von Neumann formulation; hidden-variable model; quantization.; Matematik; Mathematics;

    Sammanfattning : This doctoral thesis in mathematics consists of three articles that explore the probabilistic structure of quantum mechanics and quantization from a novel perspective.The thesis adopts a probabilistic interpretation of quantum mechanics, which views the archetypical quantum experiments of Bell- and double-slit- type as violating the principle of non-contextuality, i.
