  1. 6. Safety in Case of Fire - The Effect of Changing Regulations

    Författare :Johan Lundin; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; verification; risk analysis; uncertainty; prescriptive; risk control; building regulation; Performance-based; fire safety engineering; Teknik; Building construction; Byggnadsteknik;

    Sammanfattning : In this doctoral thesis some fundamental problems concerning society's ability to control the safety in buildings in the case of fire by issuing performance-based building regulations are identified and analysed. Fire protection documentation from forty-six projects was studied, together with a detailed analysis of the Swedish building regulations and an extensive risk analysis of a class of buildings.

  3. 7. Flywheel in an all-electric propulsion system

    Författare :Johan Lundin; Hans Bernhoff; P-O Västeräng; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flywheel; electric vehicle; hybrid vehicle; power management; energy storage;

    Sammanfattning : Energy storage is a crucial condition for both transportation purposes and for the use of electricity. Flywheels can be used as actual energy storage but also as power handling device. Their high power capacity compared to other means of storing electric energy makes them very convenient for smoothing power transients. LÄS MER

  5. 9. Differences in glycemic control in type 1 diabetes children and adolescents : in a national and international perspective and the effect on microvascular complications in young adults

    Författare :Johan Anderzén; Ulf Samuelsson; Lena Hanberger; Karin Åkesson; Carina Sparud Lundin; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This thesis focuses on glycemic control measured as HbA1c in type 1 diabetes (T1D) patients during childhood and especially during adolescence, both in a Swedish and an international context, and relates the glycemic control to the risk of complications in young adults.  In studies I and II, the Swedish Pediatric Diabetes Quality Register (SWEDIABKIDS) and the Swedish National Diabetes Register (NDR) were used.
