  1. 6. Feathers by day, membranes by night - Aerodynamic performance in bird and bat flight

    Författare :Florian Muijres; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; animal flight; aerodynamics; vortex wake; actuator disk; flight performance; span efficiency; bird; bat; wind tunnel; PIV; Pied Flycatcher; Glossophaga soricina; Leptonycteris yerbabuenae;

    Sammanfattning : The efficiency and performance of a flying animal is directly related to the aerodynamics around its body and flapping wings. Here, I have developed methods for quantifying the wake dynamics around a flying animal. The results are used to estimate the aerodynamic performance of flapping flight. LÄS MER

  3. 7. Study of heat release rates of mining vehicles in underground hard rock mines

    Författare :Rickard Hansen; Haukur Ingason; Nicholas Dembsey; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : A unique study on fire safety in hard rock underground mines with focus on heat release rates of mining vehicles is presented. A literature inventory was conducted with respect to fires in underground hard rock mines, which revealed that the most common fire cause in underground mines was flammable liquid sprayed onto hot surface and the most common fire object was a vehicle.

  4. 8. A Study of Critical Variables in the Anxiety of Schizophrenics by means of a Structured Clinical Interview and a Percept-genetic Experiment

    Författare :Dan Anders Palmquist; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Factor-analysi; Cluster-analysis; Structured Interview; Subliminal verbal stimulation; Gestalting ability; Regression; Disintegration; Subliminal perception; Psychopathology; Cognitive maturity; Affects; Anxiety; Schizophrenia Perception; Percept-genetics; Psykologi; Regression;

    Sammanfattning : Presented to 42 schizophrenic patients and 19 normals, by means of a percept-genetic technique, two motifs of mother and infant in close interaction (feeding and nursing) . The motifs were tagged, by subliminal presentation, with aggressive resp. "healing" sentences, in a balanced design. No effects of this tagging were discernible. LÄS MER

  5. 9. Monetary policy under uncertainty

    Författare :Ulf Söderström; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis contains four chapters, each of which examines different aspects of the uncertainty facing monetary policymakers.''Monetary policy and market interest rates'' investigates how interest rates set on financial markets respond to policy actions taken by the monetary authorities.

  7. 10. Predictive models for accidents on urban links - A focus on vulnerable road users

    Författare :Thomas Jonsson; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road transport technology; Transportteknik; Transport technology; Teknik; Technological sciences; Stads- och glesbygdsplanering; Town and country planning; speed; links; urban; safety; vulnerable road users; modelling; prediction; crash; traffic safety; accident; Vägtransportteknik;

    Sammanfattning : Much of earlier work on predictive models for accidents has been focused on rural traffic or urban intersections. This work has aimed at identifying and investigating possible improvements to predictive models for accidents on urban links. A special focus has been on the accidents of vulnerable road users.
