  1. 1. In-situ TEM Probing of Nanomaterials

    Författare :Magnus Hummelgård; Håkan Olin; Valeria Nicolosi; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; in situ; TEM; probing; nanowires; nanoparticles; ink; Other engineering physics; Övrig teknisk fysik; Material physics with surface physics; Materialfysik med ytfysik; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : Nanomaterials because of their small size, may have special properties unlikely to be seen in ordinary types of materials. Nanomaterials like nanotubes,nanowires and nanoparticles are best studied at the nanoscale, vital but also problematic. LÄS MER

  4. 3. Optimisation of Forest Road Investments and the Roundwood Supply Chain

    Författare :Leif Olsson; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Stochastic Programming; Scenario Analysis; Mixed-Integer Linear Programming; Forest Logistics; Upgrading of gravel roads; Business studies; Företagsekonomi; MATHEMATICS; MATEMATIK;

    Sammanfattning : In a pre-study, concerning roundwood freshness, performed by the Forestry Research Institute of Sweden during the spring of 2000, the quality on the forest road network was identified as a major problem for the Swedish forest sector. These problems mostly occur during spring thaw, but also when rains give muddy gravel roads. LÄS MER

  7. 5. Some modes of convergence and their application to homogenization and optimal composites design

    Författare :Anders Holmbom; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Homogenization; two-scale convergence; MATHEMATICS; MATEMATIK; Mathematics;

    Sammanfattning : In this thesis, we develop, extend, apply, and discuss a number of methods for the study of limits of sequences of functions and operators. The connection between the notion of two-scale convergence and more general concepts of convergence is investigated and some alternative classes of admissible test functions are characterized. LÄS MER
