  1. 1. Local structure and composition : in additively manufactured bulk metallic glasses and composites

    Author : Inga Katharina Goetz; Jochen M. Schneider; Björgvin Hjörvarsson; Ulf Jansson; Maria Teresa Pérez Prado; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; additive manufacturing; bulk metallic glasses; nanoscale clustering; convective flow; laser nitriding; laser powder bed fusion; metallic glass - ceramic composites; oxygen impurities; mechanical properties; magnetic properties; viscosity; Fysik; Physics;

    Abstract : Additive manufacturing enables the production of complex multi-material geometries and bulk metallic glass parts beyond their critical casting thickness. The local modification of structure, composition, and properties is explored in this thesis with the aim to design novel composite materials and functional gradients. READ MORE

  2. 2. Local structure in disordered materials studied by neutron scattering and RMC modelling

    Author : Liselotte Karlsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Local structure; neutron scattering; RMC modelling; metallic glasses; high Tc; superconductors; fast ion conductors; Kärnfysik; Nuclear physics; Kärnfysik; Physics Of Matter; materiefysik;

    Abstract : Different disordered materials are becoming more and more important in various technological applications. There is a need to improve our detailed understanding of the local structure of such materials and how the atomic structure is related to macroscopic physical properties. READ MORE

  3. 3. Local Structure of Hydrogen-Bonded Liquids

    Author : Matteo Cavalleri; Lars G.M. Pettersson; John Tse; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen-bond; water; ice; density functional theory; DFT; core-level spectroscopies; x-ray absorption; Physical chemistry; Fysikalisk kemi;

    Abstract : Ordinary yet unique, water is the substance on which life is based. Water seems, at first sight, to be a very simple molecule, consisting of two hydrogen atoms attached to one oxygen. READ MORE

  4. 4. Robust Image Registration for Improved Clinical Efficiency : Using Local Structure Analysis and Model-Based Processing

    Author : Daniel Forsberg; Hans Knutsson; Mats Andersson; Claes Lundström; Wiro Niessen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image registration; deformable models; scoliosis; visualization; volume rendering; adaptive regularization; GPGPU; CUDA;

    Abstract : Medical imaging plays an increasingly important role in modern healthcare. In medical imaging, it is often relevant to relate different images to each other, something which can prove challenging, since there rarely exists a pre-defined mapping between the pixels in different images.

  5. 5. Evolving Urban Culture in Transforming Cities Architectural and Urban Design in a Fluid Context

    Author : Mir Azimzadeh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evolution; generative process; space; configuration; culture; society; urban design; architecture; urban spatial systems; metamorphosis; domestic space; public space; place; analytic theory; space syntax; cultural types; local structure; urban function; housing estate; city; spatial interface; street system;

    Abstract : The practice of architectural and urban design being involved in forming the space in our cities and built environments has certain effects on the social life in society that in its turn conditions the performance of the practice. The continuous changes in cities and societies, however, are just partially caused by the practice of architectural and urban design. READ MORE
