  1. 21. Non-Linear Vibration and Dynamic Fracture Mechanics of Bridge Cables

    Författare :Armando Leon; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cable Vibrations; Non-Linear Vibration; Dynamic Fracture Mechanics; Cable-Stayed Bridges; Dynamic Stress Intensity Factor;

    Sammanfattning : In the present work, the non-linear vibrations and the corresponding dynamic fracture mechanics of cables of cable-stayed bridges are studied. The cables are among the most critical components in cable-stayed bridges and there are different damage sources such as corrosion, vibration, fatigue and fretting fatigue that can significantly affect them, thereby reducing the cable’s service life and even producing their failure.

  3. 22. Development of methods for population-based surveillance of influenza

    Författare :Hanna Merk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : When this work was initiated the infectious disease surveillance systems available to public health authorities in Sweden and elsewhere were not providing continuously updated information on individuals stricken by disease unless the individuals sought health care or considerable field work was undertaken. However, continuous information on the incidence, regardless of health care seeking behaviour, is vital when estimating the case fatality rate and societal impact of a disease, and when comparing surveillance results between countries and over time.

    Sammanfattning : Background: To accelerate the coverage of skilled birth attendance, in 2005, the Indian government initiated a conditional cash transfer (CCT) programme, Janani Suraksha Yojana (JSY) that provides cash to women upon delivering in health facilities. The attempt to increase the utilization of facilities through the JSY, given the health system’s fragile state, has raised concerns about the programme’s success at achieving its intended goal of reducing maternal mortality ratio (MMR).
