    Sammanfattning : This thesis examines written feedback on texts in a university preparatory course, Qualifying Course in Swedish for University Studies. The general aim is to illuminate feedback practices in the teaching of academic writing to adult second language students of Swedish and what characterises the feedback practices, with an interest in lecturer and student perspectives.

    Sammanfattning : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. LÄS MER

  4. 3. Multiantenna Cellular Communications : Channel Estimation, Feedback, and Resource Allocation

    Författare :Emil Björnson; Björn Ottersten; Mats Bengtsson; Marios Kountouris; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; limited feedback; multicell communications; resource allocation;

    Sammanfattning : The use of multiple antennas at base stations and user devices is a key component in the design of cellular communication systems that can meet the capacity demands of tomorrow. The downlink transmission from base stations to users is particularly limiting, both from a theoretical and a practical perspective, since user devices should be simple and power-efficient, and because many applications primarily create downlink traffic (e.

  5. 4. Learning With Selective Feedback : Effects on Performance and Coding of Unknown Outcomes

    Författare :Ebba Elwin; Peter Juslin; Robin Hogarth; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive science; Kognitionsforskning; Psychology; psykologi;

    Sammanfattning : In experiential learning, one important source of information is the feedback that people receive on the outcomes of their decisions. Typically, however, feedback is systematically absent for many decisions and the actual experience of people may therefore be highly selective. LÄS MER

  7. 5. The brain-pituitary-gonadal axis of the three-spined stickleback, Gasterosteus aculeatus

    Författare :Yi Ta Shao; Bertil Borg; Sylvie Dufou; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BPG axis; GnRH; lh-β; fsh-β; three-spined stickleback; Gasterosteus aculeatus; homeostasis; feedback; funktionell zoomorfologi; Functional Zoomorphology;

    Sammanfattning : The seasonal reproduction of the three-spined stickleback is stimulated by long day photoperiod. As in other vertebrates, the reproductive system of stickleback is regulated by the brain-pituitary-gonadal (BPG) axis which is largely controlled by feedback effects. Both negative and positive feedback effects on the BPG axis have been found in fish. LÄS MER
