  1. 1. Masking environmental feedback : Misfits between institutions and ecosystems in Belize and Thailand

    Författare :Miriam Huitric; Carl Folke; Nils Kautsky; Juan Carlos Castilla; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine reserves; ecosystem change; sequential exploitation; pathology of resource use; institutions; driving forces; coral reefs; social-ecological systems; mangroves; aquaculture; Belize; Thailand; Maine; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The thesis analyses relationships between ecological and social systems in the context of coastal ecosystems. It examines human impacts from resource extraction and addresses management and governance behind resource exploitation. LÄS MER

  3. 2. Teleoperation and the influence of driving feedback on drivers’ behaviour and experience

    Författare :Lin Zhao; Mikael Nybacka; Pernilla Ulfvengren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teleoperation; driving behaviour; driving feedback; driving performance; driving experience; motion cueing feedback; steering force feedback; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Automated vehicles (AVs) have been developing at a rapid pace over the past few years. However, many difficulties still remain for achieving full Level-5 AVs. This signifies that AVs still require human operators to intervene or assist, such as taking over control of AVs or selecting their routes. LÄS MER

  4. 3. Relay Feedback and Multivariable Control

    Författare :Karl Henrik Johansson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Frequency methods; Process control; Sequential control; Automatic tuning; Control education; Laboratory process; Performance limitations; Decentralized control; Multivariable zero; Multivariable systems; Hybrid control; Nonlinear dynamics; Limit cycles; Oscillations; Relay feedback; Sliding modes; control engineering; Automatiska system; robotteknik; reglerteknik;

    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

  5. 4. 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

  7. 5. Limited Feedback Information in Wireless Communications : Transmission Schemes and Performance Bounds

    Författare :Thanh Tùng Kim; Mikael Skoglund; Hesham El Gamal; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diversity-multiplexing tradeoff; Large deviation analysis; Limited feedback; MIMO channels; Relay channels; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis studies some fundamental aspects of wireless systems with partial channel state information at the transmitter (CSIT), with a special emphasis on the high signal-to-noise ratio (SNR) regime. The first contribution is a study on multi-layer variable-rate communication systems with quantized feedback, where the expected rate is chosen as the performance measure. LÄS MER
