1. 16. Evaluation of regression methods for log-normal data - linear models for environmental exposure and biomarker outcomes

   Författare :Sara Gustavsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; log-normal distribution; linear models; absolute effects;

   Sammanfattning : The identification and quantification of associations between variables is often of interest in occupational and environmental research, and regression analysis is commonly used to assess these associations. While exposures and biological data often have a positive skewness and can be approximated with the log-normal distribution, much of the inference in regression analysis is based on the normal distribution.

3. 17. The Syntax of Past Participles. A Generative Study of Nonfinite Constructions in Ancient and Modern Italian

   Författare :Verner Egerland; Italienska; []
   Nyckelord :HUMANIORA; HUMANITIES; Absolute Constructions; Word order and Participial Agreement in Italian; Scandinavian; and Romance; Affectedness Constraint; Medieval and Renaissance Italian; Spec head agreement and Case Theory; Antisymmetry; Past Participles; Null Objects; Italian language and literature; Italienska språk och litteratur ;

   Sammanfattning : The purpose of this thesis is double. First, it will be shown that a number of problems of the syntax of ancient, literary Italian lend themselves readily to an analysis in terms of the Theory of Principles and Parameters. LÄS MER

4. 18. Experimental study of the rotating-disk boundary-layer flow

   Författare :Shintaro Imayama; Henrik Alfredsson; Rebecca Lingwood; Benoît Pier; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; boundary layer; rotating disk; laminar-turbulent transition; convective instability; absolute instability; secondary instability; crossflow instability; hot-wire anemometry.;

   Sammanfattning : Rotating-disk flow has been investigated not only as a simple model of cross flow instability to compare with swept-wing flow but also for industrial flow applications with rotating configurations. However the exact nature of laminar-turbulent transi- tion on the rotating-disk flow is still major problem and further research is required for it to be fully understood, in particular, the laminar-turbulent transition process with absolute instability.

5. 19. Direct numerical simulations of the rotating-disk boundary-layer flow

   Författare :Ellinor Appelquist; Philipp Schlatter; Henrik Alfredsson; Rebecca Lingwood; Christopher Davies; KTH; []
   Nyckelord :Fluid mechanics; boundary layer; rotating disk; laminar-turbulent transition; convective instability; absolute instability; secondary instability; crossflow instability; direct numerical simulations; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : This thesis deals with the instabilities of the incompressible boundary-layer flow that is induced by a disk rotating in otherwise still fluid. The results presented are mostly limited to linear instabilities derived from direct numerical simulations (DNS) but with the objective that further work will focus on the nonlinear regime, providing greater insights into the transition route to turbulence.

7. 20. Auditory and Olfactory Abilities in Blind and Sighted Individuals : More Similarities than Differences

   Författare :Stina Cornell Kärnekull; Maria Larsson; Mats E Nilsson; Johan Willander; Fredrik U Jönsson; Johannes Frasnelli; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; absolute threshold; audition; autobiographical memory; blindness; discrimination; episodic recognition; identification; imagery; judgments of learning; memory; metacognition; olfaction; onset age of blindness; reminiscence bump; sensory compensation; Psychology; psykologi;

   Sammanfattning : Blind individuals face various challenges in everyday life because of the lack of visual input. However, since they need to rely on the non-visual senses for everyday tasks, for instance, when navigating the environment, the question has been raised as to whether perceptual and cognitive abilities in these senses may be enhanced.
