  1. 16. Module identification in dynamic networks: parametric and empirical Bayes methods

    Författare :Niklas Everitt; Håkan Hjalmarsson; Cristian R. Rojas; Paul Van den Hof; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The purpose of system identification is to construct mathematical models of dynamical system from experimental data. With the current trend of dynamical systems encountered in engineering growing ever more complex, an important task is to efficiently build models of these systems. LÄS MER

  3. 17. Macroeconomic Studies on Fiscal Policy and Real Exchange Rates

    Författare :Göran Hjelm; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; econometrics; economic theory; Total factor productivity; Economics; Real exchange rates; Structural VAR models; Partisan models; Fiscal policy; Fiscal contractions; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

    Sammanfattning : This thesis contains four empirical macroeconomic studies and the papers may briefly be summarized as follows. In the first paper, we use both descriptive statistics and regression analysis to investigate whether movements in real exchange rates and money supply before and during fiscal contractions matter for the macroeconomic outcome.

  4. 18. Evaluation of the Tactoid Formation in Clay Systems

    Författare :Maria Jansson; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Nano-plattor; Taktoider; Anisotropi; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; Clay; Montmorillonite; Nanoplatelets; Tactoid; Anisotropy; Coarse-grained models; MD simulations; MC simulations; SAXS; Swelling pressure;

    Sammanfattning : Clay minerals consist of anisotropic nanoplatelets where the majority of the clay minerals are highly charged, and thus, swell in aqueous solution. The structure and swelling depend on the type of clay mineral, and also on the ionic composition, and temperature. LÄS MER

  5. 19. On the Origin and Distributions of the Inclusions in Production-scale ESR and PESR Remelted Ingots and Materials from Different Ingot Sizes and Solidification Structures

    Författare :Eva Sjöqvist Persson; Pär Jönsson; Torbjörn Carlberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : The study was carried out with the aim to evaluate the origin, morphology, and distribution of the non-metallic inclusions (NMI) in electro-slag remelted (ESR) steels and in electro-slag remelted steels using a pressured controlled inert atmosphere (PESR). In addition to the NMI studies, the solidification structure in different ingot sizes were studied in order to define the influence of the solidification on the NMI characteristics. LÄS MER

  7. 20. Why don’t we mine the landfills?

    Författare :Nils Johansson; Joakim Krook; Mats Eklund; Peter Tom Jones; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : There are many reasons to mine landfills. For example, metals are increasingly shifting location from the Earth’s crust through human society into landfills. LÄS MER
