  2. 1. Plasticity Driven Damage and Void Growth

    Author : Mattias Olsson; Kärnfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; Thermal engineering; applied thermodynamics; vibration and acoustic engineering; vacuum technology; hydraulics; void growth; Mechanical engineering; damage evolution; elasto-plasticity; thermodynamics;

    Abstract : Plasticity induced damage evolution is considered using a thermodynamical approach. Different postulates on how to include the effects of damage in the constitutive equations have been studied. The results reveal that a mapping, similar to that of the stress, of both the kinematic and isotropic hardening variables is to be preferred. READ MORE

  4. 2. The void : Urban wasteland as political space

    Author : CECILIA VON SCHÉELE; Statsvetenskapliga institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban void; urban wasteland; urban planning; urban politics; space; rhythm; undecidable; montage; Derrida; Massey;

    Abstract : The rugged field and group of trees between housing estates or next to the railroad tracks, the left-over space of deserted industrial areas, the vacant demolition site of a central city block – they could all be termed ‘urban voids’. However, they are often anything but voids, in a literal sense, as they are not empty, or deserted. READ MORE

  5. 3. To void at will : lnvestigation and treatment of children with bladder dysfunction

    Author : Gunilla Gladh; Ulla Sillén; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Improvements in diagnostic and treatment procedures have made it possible to obtain a normal kidney function and continence for most children with bladder dysfunction. However, in the daily clinical work further diagnostic and treatments procedures may be required when traditional methods fail to help the child. READ MORE

  6. 4. Novel Diagnostics and Computational Methods of Neutron Fluxes in Boiling Water Reactors

    Author : John Loberg; Michael Österlund; Thomas Smed; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Void; BWR; neutron fluxes; channel bow; MCNP; 2D 3D; Physics; Fysik;

    Abstract : The focus in this thesis is to improve knowledge of the BWR related uncertainties void, channel bow, and control rods. The presence of void determines the moderation of neutrons in BWRs. A high void fraction is less efficient in moderating neutrons than a low one. READ MORE

  7. 5. Modeling the behavior of inclusions in plastic deformation of steels

    Author : Chunhui Luo; KTH; []
    Keywords : Inclusion; Steel; Plastic deformation; Void; Rolling; Forging; Finite element; Mesomechanical approach;

    Abstract : This doctoral thesis presents a modeling method fordemonstrating the behavior of inclusions and their surroundingmatrix during plastic deformation of steels.Inclusions are inescapable components of all steels. READ MORE
