    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; non-orthogonality; non-equilibrium; transport; nanosystem; quantum dot; spin-dependent; renormalization; Green function; diagram technique; many-body states; Hubbard operator; electron correlations; time-dependent; Fysik; icke-ortogonal; icke-jämvikt; transport; nanosystem; kvantprick; spinberoende; renormering; Green-funktion; diagramteknik; mångkropparstillstånd; Hubbadoperator; elektronkorrelationer; tidsberoende; Physics; Fysik; Fysik; Physics;

    Sammanfattning : The concept of the transfer Hamiltonian formalism has been reconsidered and generalized to include the non-orthogonality between the electron states in an interacting region, e.g. quantum dot (QD), and the states in the conduction bands in the attached contacts. LÄS MER

  3. 7. Essays on Financial Market Interdependence

    Författare :Lu Liu; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Stock markets; commodity futures; extreme downside risk; regime-switching; correlations; diversification; market linkages; heterogeneity; EMU stock markets; dynamic panel data;

    Sammanfattning : This thesis aims at investigating the risk spillover and correlations among national stock markets, and the structure of dependence between stocks and commodity futures. It consists of four chapters. Chapter 1 briefly reviews the literature background of financial market interdependence and summarizes the contribution of the thesis. LÄS MER

  4. 8. The Dark Side of Decentralized Target Tracking : Unknown Correlations and Communication Constraints

    Författare :Robin Forsling; Fredrik Gustafsson; Gustaf Hendeby; Zoran Sjanic; Simon Julier; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Using sensors to observe real-world systems is important in many applications. A typical use case is target tracking, where sensor measurements are used to compute estimates of targets. Two of the main purposes of the estimates are to enhance situational awareness and facilitate decision-making. Hence, the estimation quality is crucial. LÄS MER

  5. 9. Heat transfer in falling film evaporation of black liquor - Experiments and theory

    Författare :Miriam Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evaporator; black liquor; falling film; kraft pulp mill; Heat transfer; evaporation; viscosity; correlations; experimental; non-Newtonian;

    Sammanfattning : Pulp and paper industry uses a large part of the total amount of energy in industry in Sweden. The evaporation plant has the major energy demand in the kraft pulp mill, which is the dominant type of chemical pulp mill. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. LÄS MER
