  1. 6. Bracing of steel bridges during construction; theory, full-scale tests and simulations

    Author : Hassan Mehri; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

    Abstract : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.

  2. 7. Extensions of the kernel method of test score equating

    Author : Gabriel Wallin; Marie Wiberg; Jenny Häggström; Anton A. Béguin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Test equating; Nonequivalent groups; Standard error of equating; bandwidth selection; log-linear models; item response theory; Statistics; statistik;

    Abstract : This thesis makes contributions within the area of test score equating and specifically kernel equating. The first paper of this thesis studies the estimation of the test score distributions needed in kernel equating. READ MORE

  3. 8. Motivational beliefs in the TIMSS 2003 context : Theory, measurement and relation to test performance

    Author : Hanna Eklöf; Widar Henriksson; Simon Wolming; Svein Lie; Umeå universitet; []
    Keywords : test-taking motivation; TIMSS 2003; validity; construct validation; measurement; expectancy-value theory; self-concept; task value; factor analysis; eighth-grade students; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : The main objective of this thesis was to explore issues related to student achievement motivation in the Swedish TIMSS 2003 (Trend in International Mathematics and Science Study) context. The thesis comprises of five empirical papers and a summary. READ MORE

  4. 9. Aspects of Yang-Mills Theory : Solitons, Dualities and Spin Chains

    Author : Lisa Freyhult; Antti Niemi; Poul Damgaard; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical Physics; Field theory; String theory; Yang-Mills; Effective models; Supersymmetry; Solitons; Fermion number; Duality; AdS CFT correspondence; Bethe ansatz; Teoretisk fysik; Physics; Fysik;

    Abstract : One of the still big problems in the Standard Model of particle physics is the problem of confinement. Quarks or other coloured particles have never been observed in isolation. Quarks are only observed in colour neutral bound states. The strong interactions are described using a Yang-Mills theory. READ MORE

  5. 10. Test Design for Mean Ability Growth and Optimal Item Calibration for Achievement Tests

    Author : Jonas Bjermo; Frank Miller; Marie Wiberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; test design; item response theory; optimal experimental design; SweSAT; item calibration; vertical scaling; ability growth; computerized adaptive tests; Statistics; statistik;

    Abstract : In this thesis, we examine two topics in the area of educational measurement. The first topic studies how to best design two achievement tests with common items such that a population mean-ability growth is measured as precisely as possible. The second examines how to calibrate newly developed test items optimally. READ MORE
