  1. 6. On Rank-invariant Methods for Ordinal Data

    Författare :Yishen Yang; Sune Karlsson; Elisabeth Svensson; Rolf Larsson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ordinal data; rank-invariance; systematic change; agreement; association; inter-rater reliability; ranking; Spearman; multi-item scale; Statistik; Statistics;

    Sammanfattning : Data from rating scale assessments have rank-invariant properties only, which means that the data represent an ordering, but lack of standardized magnitude, inter-categorical distances, and linearity. Even though the judgments often are coded by natural numbers they are not really metric. LÄS MER

  3. 7. Product support and spare parts considering system reliability and operating environment

    Författare :Behzad Ghodrati; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : The required spare parts planning for a system/machine is an integral part of the product support strategy. The number of required spare parts can be effectively estimated on the basis of the product reliability characteristics. LÄS MER

  4. 8. Some applications of CALPHAD techniques to diffusion reactions in gradient materials

    Författare :Thomas Helander; KTH; []
    Nyckelord :;

    Sammanfattning : In gradient materials, i.e. materials that have varyingproperties due to an inhomogeneous chemical composition, thereis usually a strong driving force for diffusion reactions inthe gradient zone. Such reactions may have a strong influenceon the properties of the material. LÄS MER

  5. 9. Passenger assessments of quality in local public transport- measurement, variability and planning implications

    Författare :Helena Sjöstrand; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passenger; public transport; quality; survey; Stated Preference; assessment; assignment; planning; Transportteknik; Transport technology; Road transport technology; Vägtransportteknik;

    Sammanfattning : The aim of this work was to get a more detailed basis for planning of local public transport. With more knowledge of how segments of travellers assess different parts of a journey, bus routes can be planned to fit either all passengers or selected groups better. LÄS MER

  7. 10. Order in Strongly Correlated Quasi-One-Dimensional Systems : Solving Higher-Dimensional Systems Combining Matrix-Product-State Methods and Mean-Field Theory

    Författare :Gunnar Bollmark; Adrian Kantian; Annica M. Black-Schaffer; Fabian Heidrich-Meisner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; strongly correlated systems; matrix-product states; quasi-one-dimensional; Hubbard model; mean-field theory; first-principles calculations.; Fysik; Physics;

    Sammanfattning : Since their discovery the understanding of unconventional superconductors (USCs) has posed a great challenge in condensed matter physics. One central problem, both of theory and experiment, lies in determining the microscopic origin of electron pairing in such systems. LÄS MER
