  1. 6. Three aspects of packet forwarding in the Internet

    Författare :Mikael Degermark; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : This thesis addresses packet forwarding in packet-switching networks such as the Internet. The interconnection points tying transmission links together in such networks are called routers, computers that may be specialized for the task. Routers need to decide where, when, and in what form each packet should be forwarded. LÄS MER

  3. 7. Surface complexation in natural particle suspensions

    Författare :Qing Du; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : This thesis is a summary of our studies on (i) the proton and copper adsorption at aqueous illite surfaces, (ii) the proton and copper complexation of humic substances (fulvic acid FA and humic acid HA), (iii) the interaction between illite and fulvic acid, and (iv) the copper complexation behaviors in illite-FA bi-complexant systems. These particular studies were designed to help us develop a framework for modelling heavy metal complexation/adsorption mechanisms at natural particle surfaces. LÄS MER

  5. 9. Experimental and theoretical investigations into the streaming potential phenomenon with special reference to applications in glaciated terrain

    Författare :Johan Friborg; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Sammanfattning : The occurrence of an electrical potential difference between the ends of a capillary tube when a fluid flows through is known as the streaming potential phenomenon. It was reported by Quincke in 1859 and was studied by Helmholtz, among others, in the nineteenth century. LÄS MER

  7. 10. Fatigue damage mechanisms in polymer matrix composites

    Författare :Kristofer Gamstedt; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Polymer matrix composites are finding increased use in structural applications, in particular for aerospace and automotive purposes. Mechanical fatigue is the most common type of failure of structures in service. The relative importance of fatigue has yet to be reflected in design where static conditions still prevail. LÄS MER
