  2. 11. On the modelling of turbulent flow and mixing in stirred reactors

    Author : Johan Revstedt; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; CFD; stirred reactors; impeller modelling; Energy research; mixing; LES; Energiforskning;

    Abstract : This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. READ MORE

    Author : Olof Stjernström; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Migration in Sweden; Migration theory; Social network; Migration decisions; Geographical preferences;

    Abstract : This study deals with long distance migration together with the importance of social networks and geographical preferences for the choice of destination when moving. Thus, the main purpose of this study is to analyze and specify the importance of the mover's social contacts when choosing a new place-of residence. READ MORE

  5. 13. Image segmentation using snakes and stochastic watershed : with applications to microscopy images of biological tissue

    Author : Bettina Selig; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The purpose of computerized image analysis is to extract meaningful information from digital images. To be able to find interesting regions or objects in the image, first, the image needs to be segmented. This thesis concentrates on two concepts that are used for image segmentation: the snake and the stochastic watershed. READ MORE

  6. 14. Some asymptotic results in dependence modelling

    Author : Jens Svensson; Boualem Djehiche; Allan Gut; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik;

    Abstract : This thesis consists of two papers, both devoted to the study of asymptotics in dependence modelling. The first paper studies large deviation probabilities for a sum of dependent random variables, where the dependence stems from a few underlying random variables, so-called factors. READ MORE
