  1. 1. CFD Methods for Predicting Aircraft Scaling Effects

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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.

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

    Author : Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
    Keywords : HUMANITIES; HUMANIORA; 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;

    Abstract : 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. READ MORE

  5. 5. Correlation Effects in Nanostructures

    Author : Paata Kakashvili; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conformal field theory; Coulomb blockade; Wigner crystal.; Strongly correlated electrons; Kondo effect; bosonization; Luttinger liquid; STM; single-electron transistor;

    Abstract : In this Ph.D. thesis I present the background and providefurther details to the work presented in the appended papers. The background consists of brief overviews of Kondo physics, Luttinger liquid theory, and conformal field theory. READ MORE
