  2. 1. A Ventilation Strategy Based on Confluent Jets : An Experimental and Numerical Study

    Author : Setareh Janbakhsh; Bahram Moshfegh; Alexander Zhivov; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple interacting jets; round jets; confluent jets; wall jet; ventilation strategy; air distribution system; air supply device; ventilation performance; thermal comfort; energy-saving potential; measurement; numerical predictions; RANS turbulence models; renormalization group RNG k– ε ; realizable Re k– ε ; and shear stress transport SST k– ω ;

    Abstract : This study presents air distribution systems that are based on confluent jets; this system can be of interest for the establishment of indoor environments, to fulfill the goals of indoor climate and energy-efficient usage. The main objective of this study is to provide deeper understanding of the flow field development of a supply device that is designed based on wall confluent jets and to investigate the ventilation performance by experimental and numerical methods.

  4. 2. 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

  5. 3. On the subjective–objective distinction for measures of memory and cognition : Theoretical and methodological issues in questionnaire development and validation

    Author : Peter Vestergren; Widar Henriksson; Christina Wikström; Michael Rönnlund; Björn Lyxell; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive dysfunction; measurement; memory complaints; self report; subjective memory; subjective–objective; Other social sciences; Övrig samhällsvetenskap; didactics of educational measurement; beteendevetenskapliga mätningar;

    Abstract : The aim of this thesis was to develop a questionnaire for cognitive functioning, which could possibly be used as a screening instrument for early signs of dementia in the future. The introduction discusses the often made distinction between subjective and objective measures. READ MORE

  6. 4. Wafer Bonding for Spaceflight Applications : Processing and Characterisation

    Author : Kerstin Jonsson; Maaike Visser-Taklo; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; wafer bonding; oxygen plasma; wet chemical; anodic bonding; gamma irradiation; proton irradiation; temperature cycling; vibration; shock; Weibull; adhesion quantification; double cantilever beam; tensile; chevron; blister; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : Bonding techniques intended for assembling space microsystems are studied in this work. One of the largest problems in bonding pre-processed semiconductor wafers are the severe process restrictions imposed by material compatibility issues. READ MORE

  7. 5. Detection of myocardial ischemia : clinical and experimental studies with focus on vectorcardiography, heart rate and perioperative conditions

    Author : Sören Häggmark; Ulf Näslund; Michael F Haney; Mårten Rosenqvist; Umeå universitet; []
