  1. 1. Combinatorial Considerations on Two Models from Statistical Mechanics

    Författare :Johan Thapper; Svante Linusson; Peter Jonsson; Jakob Jonsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fully packed loop model; rhombus tilings; hard particle model; independence complex; discrete morse theory; Discrete mathematics; Diskret matematik;

    Sammanfattning : Interactions between combinatorics and statistical mechanics have provided many fruitful insights in both fields. A compelling example is Kuperberg’s solution to the alternating sign matrix conjecture, and its following generalisations. LÄS MER

  3. 2. Mångsynthet och mångfald : om lärarstudenters förståelse av och undervisning för hållbar utveckling

    Författare :Gunnar Jonsson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : This thesis focuses on complex understanding of sustainable development: what it is, how it can be understood by student teachers, and what affects the complexity that is discernible among pupils taught by student teachers. Three different substudies based on one another, give answers to the research questions. LÄS MER

  4. 3. Sensing and Making Sense : Designing Middleware for Context Aware Computing

    Författare :Martin Jonsson; Carl Gustaf Jansson; Anind K. Dey; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Computing devices are becoming wireless, smaller and embedded into other artifacts. Some of them are mobile while others are built into the environment. The novel technologies are also becoming more dependent of communication with other computing devices over different kinds of networks. LÄS MER

  5. 4. The impact of groundwater chemistry on the stability of bentonite colloids

    Författare :Sandra Garcia Garcia; Mats Jonsson; Per Claesson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear chemistry; Kärnkemi;

    Sammanfattning : I det svenska djupförvaret för kärnbränsle ska kompakterad bentonit användas som barriär mellan kopparkapslar med utbränt kärnbränsle och berget. I kontakt med vattenförande sprickor kan bentonitbarriären under vissa omständigheter avge montmorillonitkolloider. LÄS MER

  7. 5. Combustion dynamics and melt dripping of ethylene-acrylate copolyer composites

    Författare :Roland H. Krämer; Ulf W. Gedde; Mats Jonsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; methacrylic acid; ethylene; calcium carbonate; ionomer; nanoparticles; intumescence; halogen-free; flame retardant; melt dripping; Polymer chemistry; Polymerkemi;

    Sammanfattning : The degradation and combustion of blends of ethylene-acryalte copolymer with calcium carbonate and silicone were studied by a combination of flammability tests, in-situ measurements and analytical experiments. Compounds of poly(ethylene-co-methacrylic acid) blended with precipitated calcium carbonate nanoparticles were prepared. LÄS MER
