  1. 21. Durability of sprayed concrete : steel fibre corrosion in cracks

    Författare :Erik Nordström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : A combination of sprayed concrete technique and steel fibre technology gives obvious advantages when saving the work needed to place conventional reinforcement. In rock strengthening applications this is most accentuated. Sprayed concrete in general, made by skilled workmen, will generally be of high quality and good durability. LÄS MER

  3. 22. Functional materials studies by Mössbauer spectroscopy

    Författare :Erik Nordström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Mössbauer spectroscopy has been used as a powerful tool to investigate the local properties of some materials suitable as active ingredients in technological applications. The magnetic properties of some magnetic multilayers were investigated using conversion electron Mössbauer spectroscopy. LÄS MER

  4. 23. Samordnad individuell plan (SIP) : Professionellas samt barn och föräldrars erfarenheter

    Författare :Erik Nordström; Sofia Kjellström; Berith Hedberg; Iréne Josephson; Johan Berlin; Jönköping University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Introduktion. Många barn och unga idag har så pass komplexa behov att de behöver samtidiga insatser från olika huvudmän. Insatserna blir alltmer specialiserade och fragmenterade, vilket kräver att professioner inom hälso- och sjukvård, socialtjänst och skola samverkar. LÄS MER

  5. 24. Steel fibre corrosion in cracks : durability of sprayed concrete

    Författare :Erik Nordström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Steel fibre reinforced sprayed concrete is common practice for permanent linings in underground construction. Today there is a demand on "expected technical service life" of 120 years. Thin steel fibres could be expected to discontinue carrying load fast with a decrease of fibre diameter caused by corrosion, especially in cracks. LÄS MER

  7. 25. Interference Rejection and Channel Detection in Mobile Communication

    Författare :Fredrik Nordström; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; detection of abrupt changes; WCDMA; Viterbi decoder; Kalman filter; co-channel interference; TDMA; EDGE; Mathematics; Matematik;

    Sammanfattning : This thesis is devoted to statistical problems in mobile communication, in particular disturbance rejection and change detection are studied. Co-channel interference is a significant problem for systems based on TDMA, e.g. EDGE. LÄS MER
