  1. 1. Laser sintered materials with Non-equilibrium structures

    Författare :Bin Qian; Zhijian Shen; Germán F. de la Fuente; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser sintering; Materials; Non-equilibrium structures; microstructure; hierarchical structure; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : This thesis is focused on achieving materials with non-equilibrium structures fabricated by high-energy laser sintering. The chosen precursor materials have rigid and inert structures like high-melting point ceramics or metals. LÄS MER

  3. 2. Multimodal Imaging of Anisotropic Hierarchical Materials

    Författare :Adrian Rodriguez Palomo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomaterials; Hierarchical Materials; Multimodal Imaging; Birefringence; X-Ray Scattering;

    Sammanfattning : The thesis is focused on studying the nanostructure of natural and synthetic hierarchical materials with biological applications, using X-ray scattering imaging and birefringence microscopy. The term "hierarchical materials" is used for structures composed of sub-units organised in different length scales that create the building blocks for the next level. LÄS MER

  4. 3. On Postbuckling Analysis of Thin-walled Structures Numerical and Statistical Approaches

    Författare :Mats Ander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; postbuckling; hierarchical elements; imperfection sensitivity; displacement gradients; total Lagrange formulation; geometrically non-linear structures;

    Sammanfattning : Thin-walled structural elements, such as plates, shells and beams are important load carrying components in civil-, mechanical-, automotive- aeronautical- and marine engineering structures. In order to reduce the weight thin-walled structures are given an optimum design making them sensitive to unforeseen deviations in geometry, boundary conditions, material properties and applied loads.

  5. 4. Hierarchical structures and extended motion information for video coding

    Författare :Astrid Lundmark; John Håkon Husøy; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The thesis describes usage and generation of motion information in the field of video coding. Hierarchical structures for computation of this motion information are suggested. These hierarchical structures can be used also for other applications. LÄS MER

  7. 5. Konzeptuelle Struktur und materielle Manifestation : Nominale Part-Whole-Konstruktionen aus einer typologischen Perspektive

    Författare :Daniel Ormelius; Tyska; []
    Nyckelord :HUMANIORA; HUMANITIES; typological patterns; spatial representations; conceptual structures; morphosyntactic structures; ‘part-whole’ constructions; boundedness; internal structure; quantification; referentiality; quantifier phrase; noun phrase; determiner phrase; German language and literatur; Tyska språk och litteratur ;

    Sammanfattning : The aim of this thesis is to investigate the relation between intrasubjective mental representations – ‘conceptual structures’ – and their intersubjectively available material manifestation, in particular morphosyntactic representations. Such an investigation presupposes the analysis of not only extralinguistically established modules but also of structural levels that are inherent components of the language system. LÄS MER
