  4. 8. Realising full-scale control in wastewater treatment systems using in situ nutrient sensors

    Författare :Pernille Ingildsen; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; control engineering; Instrumentation; Wastewater treatment; Control; Full-scale plants; Control structures; Electronics and Electrical technology; Elektronik och elektroteknik; robotics; Automation; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology;

    Sammanfattning : Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. LÄS MER

  5. 9. Active Flow Control for Reducing Drag on Trucks: from Concept to Full Scale Testing

    Författare :Guglielmo Minelli; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AFC; Experiments; Vehicle Aerodynamics; Partially-Averaged Navier-Stokes; PANS; LES; Wind Tunnel; POD; Active Flow Control; Large Eddy Simulations; Proper Orthogonal Decomposition; PIV;

    Sammanfattning : There is no doubt that road vehicle transportation is needed to improve efficiency, to reduce power consumption and to contribute to a sustainable mobility. Aerodynamics plays a crucial role in this, and its optimization can have a significant impact on fuel efficiency. LÄS MER

  7. 10. On some Fatigue Problems Related to Steel Bridges

    Författare :Roberto Crocetti; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modular bridge expansion joints; full-scale testing; web breathing; postbuckling behaviour; fatigue; riveted connections;

    Sammanfattning : This thesis concerns three specific fatigue topics related to steel members in bridges, namely: (1) Modular Bridge Expansion Joints (MBEJs). Several premature fatigue failures of MBEJs have occurred in Europe and USA during the past decades. LÄS MER
