  1. 21. Bracing of steel bridges during construction; theory, full-scale tests and simulations

    Författare :Hassan Mehri; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

    Sammanfattning : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.

    Sammanfattning : Handling of granular material occurs all over the world for different reasons and under different conditions. In the mining industry, granular material handling is present in almost all processes. The machinery that deals with the granular material is typically subjected to significant wear. The loading process is a very crucial task in any mine. LÄS MER

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

    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. 25. Evaluation of medical response in disaster preparedness : with special reference to full-scale exercises

    Författare :Monica Rådestad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Air crash;

    Sammanfattning : Background: Disaster exercises and simulations serves as teaching and training tool for improving medical response in disaster preparedness. Rapid and effective medical response in major incidents is known as a “key phase” to optimise resources, and this requires that management systems have an “all hazards” approach. LÄS MER
