1. 1. Scaling sufficiency : Towards less material consumption

   Författare :Ola Persson; Karin Bradley; Mikael Klintman; Kersty Hobson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Urban and Regional Studies; Urbana och regionala studier;

   Sammanfattning : Various researchers have pointed out that avoiding further catastrophicconsequences related to the deteriorating ecological state of the planet,brought about by unsustainable production and consumption patterns,requires not only technological innovation and efficiency in productionprocesses, but also absolute reductions in energy and material use (i.e. LÄS MER

3. 2. CFD Methods for Predicting Aircraft Scaling Effects

   Författare :Karl Pettersson; Arthur Rizzi; Bryan Richards; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Scaling Effects; Boundary Layer Transition; Preconditioning; Vehicle engineering; Farkostteknik;

   Sammanfattning : This thesis deals with the problems of scaling aerodynamic data from wind tunnel to free flight  conditions. The main challenges when this scaling should be performed is how the model support, wall interference and the potentially lower Reynolds number in the windtunnel should be corrected. LÄS MER

4. 3. Expecting Happy Women, Not Detecting the Angry Ones : Detection and Perceived Intensity of Facial Anger, Happiness, and Emotionality

   Författare :Tonya S. Pixton; Åke Hellström; Maria Larsson; James A. Russell; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Signal Detection Perception ; Happiness; Anger; Face Perception; Facial Expressions; Superiority Effects; Gender Differences; Response Bias; Scaling; Euclidean Distance; Psychology; Psykologi; Psychology; psykologi;

   Sammanfattning : Faces provide cues for judgments regarding the emotional state of individuals. Using signal-detection methodology and a standardized stimulus set, the overall aim of the present dissertation was to investigate the detection of emotional facial expressions (i.e., angry and happy faces) with neutral expressions as the nontarget stimuli.

5. 4. Scaling techniques using CFD and wind tunnel measurements for use in aircraft design

   Författare :Karl Pettersson; Arthur Rizzi; Henrik Alfredsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; wind tunnel; scaling; Reynolds number effect; Vehicle engineering; Farkostteknik;

   Sammanfattning : This thesis deals with the problems of scaling aerodynamic data from wind tunnel conditions to free flight. The main challenges when this scaling should be performed is how the model support, wall interference and the potentially lower Reynolds number in the wind tunnel should be corrected. LÄS MER

7. 5. The language learning infant: Effects of speech input, vocal output, and feedback

   Författare :Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; human; language; language acquisition; perception; production; humanoid; development; model; embodied system; speech signal processing; vocal tract morphology; acoustic; speech input; information processing; scaling; interaction; growth; infant; imitation; feedback; perceptual salience; modeling; Phonetics; Fonetik; Phonetics; fonetik;

   Sammanfattning : This thesis studies the characteristics of the acoustic signal in speech, especially in speech directed to infants and in infant vocal development, to gain insight on essential aspects of speech processing, speech production and communicative interaction in early language acquisition. Three sets of experimental studies are presented in this thesis. LÄS MER
