  1. 21. Cykler och loopar i Salongen : En studie av återkoppling i frisörklassrummet

    Författare :Anna Öhman; Hector Pérez Prieto; Anna Lena Göransson; Marie Karlsson; Anders Jönsson; Karlstads universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Feedback; assessment; classroom; multimodal social semiotics; communication; vocational education; knowing; Återkoppling; bedömning; yrkesutbildning; multimodal socialsemiotik; kommunikation; kunnande; klassrum; Pedagogiskt arbete; Educational Work;

    Sammanfattning : The interest in this empirical study aims at assessment, more precisely feedback as part of ordinary activities within hairdressing education. The study investigates feedback practices related to assessment of knowing during production, with focus on communication between student and teacher. LÄS MER

  3. 22. 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

  4. 23. On sensory feedback in hand prostheses

    Författare :Christian Antfolk; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prosthetic hands; sensory feedback.;

    Sammanfattning : Amputation of the hand implies the loss of the ability to grasp and the ability to "feel". The grasping function can be primitively restored using an active prosthesis. Multi­articulating electrically powered hands have recently made their way to the market and these hands provide enhanced grasping and gripping capabilities. LÄS MER

  5. 24. Quantized Feedback for Slow Fading Channels

    Författare :Thanh Tùng Kim; Mikael Skoglund; Geir Øien; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fading channels; information rates; feedback communications; diversity methods; MIMO systems; power control; adaptive systems; quantization.; Telecommunication; Telekommunikation;

    Sammanfattning : Two topics in fading channels with a strict delay constraint and a resolution-constrained feedback link are treated in this thesis. First, a multi-layer variable-rate single-antenna communication system with quantized feedback, where the expected rate is chosen as the performance measure, is studied under both short-term and long-term power constraints.

  7. 25. Systematic Design of Linear Feedback Amplifiers

    Författare :Martin Lantz; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Volterra series; dynamic distortion; clipping; nonlinear distortion; systematic design; feedback amplifier; Signalbehandling;

    Sammanfattning : This work adds a quantitative description of distortion to the structured design method of negative-feedback amplifiers. It constitutes a power-series representation of the feedback amplifier, which may include dynamic (memory) effects, where the design parameters appear explicitly. LÄS MER
