  1. 1. Modeling defect structure evolution in spent nuclear fuel container materials

    Författare :Arash Hosseinzadeh Delandar; Pavel Korzhavyi; Rolf Sandström; Konstantin Khromov; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron insert; First principles calculations; Point defects; Effective interaction energy; Late blooming phase; Dislocation dynamics; High strain rate deformation; Single-crystal copper; Copper canister; Creep; Glide; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Materials intended for disposal of spent nuclear fuel require a particular combination of physical and chemical properties. The driving forces and mechanisms underlying the material’s behavior must be scientifically understood in order to enable modeling at the relevant time- and length-scales. LÄS MER

  3. 2. Experimental test setups and simulations in skiing mechanics

    Författare :Mikael Swarén; Anders Eriksson; Thomas Stöggl; KTH; []
    Nyckelord :sports equipment; test methods; sports mechanics; alpine skiing; cross-country skiing; poles; helmets; glide; performance;

    Sammanfattning : Product testing and development are essential parts in sports and for the athletes in their quest to reach the podium. Manufacturers of sports equipment often use basic test methods which do not test the equipment in a sports specific way. LÄS MER

  4. 3. High Frequency Microwave and Antenna Devices based on Transformation Optics and Glide-Symmetric Metasurfaces

    Författare :Mahsa Ebrahimpouri; Oscar Quevedo-Teruel; Nader Engheta; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Glide Symmetry; Transformation Optics; Lens Antennas; High Frequency; Microwave Devices; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The new generation of wireless communication networks intends to support data rate of Gbit/s. One solution to make it possible is to move upwards in frequency range to employ the unused spectrum in mm-wave frequencies. LÄS MER

  5. 4. Investigation of the most essential factors influencing ski glide

    Författare :Leonid Kuzmin; Mikael Jonsson; Mats Tinnsten; Lars-Erik Persson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wax; Computer Aided Design;

    Sammanfattning : There are many different parameters of a ski running surface (material, roughness, hydrophobicity, etc.). All the parameters have an influence on ski glide, some more and some less. Furthermore, some parameters with only minor relevance are commonly declared as critical, while truly critical parameters, as far as we know, never been investigated. LÄS MER

  7. 5. Interfacial kinetic ski friction

    Författare :Leonid Kuzmin; Mats Tinnsten; Jonas Danvid; Mikael Jonsson; Roland Larsson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ski glide; ski base; ski wax; hydrophobicity; UHMWPE; PTFE; topography; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : It is no doubt, that the ski glide over the snow is a very complicated object of research. However, ski glide is just a one area of many other areas of human knowledge. As a rule, the scientists and practitioners, who work in these areas, operate with some publicly expressed more or less solid hypotheses. LÄS MER
