  1. 6. Internal Dosimetry in Nuclear Fuel Fabrication : Occupational Exposure to Uranium Aerosols

    Författare :Edvin Hansson; Mats Eriksson; Håkan Pettersson; Per Roos; Michael Sandborg; Bastian Breustedt; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Uranium; Aerosol; Internal; Dose; Nuclear;

    Sammanfattning : The production of nuclear fuel can be associated with occupational exposure to ionizing radiation from radioactive decay of uranium. Such exposure must be sufficiently low and radiation doses adequately determined. Radiation doses from internal exposure, i.e. LÄS MER

  3. 7. Analysis and control of a hybrid vehicle powered by free-piston energy converter

    Författare :Jörgen Hansson; Mats Leksell; Chandur Sadarangani; Anders Malmquist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-piston energy converter; FPEC; series hybrid electric vehicle; SHEV; power management; energy management; powertrain evaluation; equivalent consumption minimisation; ECMS; linear engine; Electrical engineering; Elektroteknik;

    Sammanfattning : The introduction of hybrid powertrains has made it possible to utilise unconventional engines as primary power units in vehicles. The free-piston energy converter (FPEC) is such an engine. It is a combination of a free-piston combustion engine and a linear electrical machine. LÄS MER

  4. 8. A Framework for Evaluation of Flood Management Strategies

    Författare :Karin Hansson; Love Ekenberg; Mats Danielson; Anna Vári; Stockholms universitet; []
    Nyckelord :flood; decision; multi criteria; simulation; evaluation; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : During the last decades, a great deal of attention has been focused on the financial risk management of natural disasters. The reason is that the economic losses from floods, windstorms, earthquakes and other disasters in both the developing and developed countries are escalating dramatically. LÄS MER

    Sammanfattning : Over time, the state has undertaken various reforms to govern the development of education. The issue of using new media may be seen as such an example. A change in the use of media in education imposes great challenges on both municipalities and teachers. LÄS MER

  7. 10. New methods for improving winter road maintenence

    Författare :Mats Riehm; Per-Erik Jansson; Torbjörn Gustavsson; Klas Hansson; Meelis Mölder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Winter road maintenance; Sensors; Infrared thermometry; Energy efficiency; De-icing salt; Other civil engineering and architecture; Övrig samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Winter road maintenance activities are crucial for maintaining the accessibility and traffic safety of the road network during winters. Common winter road maintenance activities include plowing and the use of de-icing agents (e.g. NaCl) to avoid freezing. LÄS MER
