  2. 1. Towards optimal railway track utilization based on societal benefit

    Author : Victoria Svedberg; Aronsson Martin; Martin Joborn; Jan T. Lundgren; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Infrastructure managers in railway systems are striving to have as efficient track utilization as possible. There are no unanimous interpretation of efficiency in terms of track utilization, but the aim of the Swedish Transport Administration is to allocate track capacity such that societal benefit is maximized.

  4. 2. Striving for self-esteem : Conceptualizations and role in burnout

    Author : Victoria Blom; Maarit Johnson; Petra Lindfors; Martin Bäckström; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; self-esteem; contingent self-esteem; burnout; stressors; gender; stress; work; competence; performance; Psychology; Psykologi; psykologi; Psychology;

    Abstract : When self-esteem is dependent on competence individuals invest a great deal of effort in their accomplishments in order to validate themselves. The aim of the present thesis was to develop a theoretically sound and valid concept and measure of contingent self-esteem dependent on competence, and examine its vulnerable implications and role in burnout.

  5. 3. Processes important for forecasting of clouds over snow

    Author : Martin Hagman; Gunilla Svensson; Victoria Sinclair; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Boundary-layer meteorology; WRF; Initialization; Stratocumulus clouds; Parameterization; Stable boundary layer; Single Column Model; meteorologi; Meteorology;

    Abstract : The Swedish Armed Forces setup of the Weather Research and Forecasting Model (WRF) has problems to forecast low clouds in stably stratified conditions when the ground is covered by snow. The aim of this thesis is to understand what causes this deficit. READ MORE

  6. 4. Evaluation of a thermally driven heat pump for solar heating and cooling applications

    Author : Corey Blackman; Chris Bales; Eva Thorin; Victoria Martin; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar energy; solar heating and cooling; sorption integrated; Reesbe företagsforskarskola; Reesbe företagsforskarskola; Energy- and Environmental Engineering;

    Abstract : Exploiting solar energy technology for both heating and cooling purposes has the potential of meeting an appreciable portion of the energy demand in buildings throughout the year. By developing an integrated, multi-purpose solar energy system, that can operate all twelve months of the year, a high utilisation factor can be achieved which translates to more economical systems.

  7. 5. Assessing the reliability of detrital zircon in Early-Earth provenance studies

    Author : Ross Kielman; Martin Whitehouse; Alexander Nemchin; Victoria Pease; Marlina Elburg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geology; geologi;

    Abstract : Our understanding of the Early Earth and the processes that have shaped its evolution have spawned predominantly from the geochemical and isotopic signatures of a small number of zircon populations around the world. Studies of trace element distributions, Hf and O isotope systematics as well as mineral inclusion chemistry in detrital zircon are combined with U-Pb chronology in order to constrain source rock characteristics.
