  1. 16. Prognos av vägars bärförmåga vid tjällossningen : användning av temperatur som nyckeltal

    Författare :Andreas Berglund; Rolf Magnusson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The global trend towards a warmer climate and temperatures near or just above 0 °C during winter months, will most likely be more common in future. One of the consequences of this climate change could, in a worst-case scenario, be freezing and thawing over a significant part of the winter with corresponding road bearing capacity problems.

  7. 20. Game Theory and Agents

    Författare :Stefan J. Johansson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Game Theory; Multi-Agent Systems; No Free Lunch Theorem; Characteristic Distributions;

    Sammanfattning : A fundamental problem in multi agent systems is conflict resolution. A conflict occurs in general when the agents have to deal with inconsistent goals, such as a demand for shared resources. We investigate how a game theoretic approach may be a helpful and efficient tool in examining a class of conflicts in multi agent systems. LÄS MER
