  1. 1. Aspects of Static Multi-Class Traffic equilibria under Congestion Pricing

    Författare :Per Olov Lindberg; Lars-Göran Mattsson; David Watling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic; congestion pricing; equilibria; marginal social cost; Other civil engineering and architecture; Övrig samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Congestion charging is a now accepted means of influencing traffic to behave in a more socio-economic optimal way, like e.g. in the Stockholm project. Already early work, in the 1920’s, showed that road use can be inefficient due externalities, i. LÄS MER

  3. 2. Theoretical Studies of Surface Forces and Phase Equilibria

    Författare :Jan Forsman; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; simulations; phase equilibria; hydrophobic interactions; hydration; Fysikalisk kemi; Physical chemistry;

    Sammanfattning : The interaction between large hydrophobic and hydrophilic surfaces in aqueous solution is investigated, using Metropolis Monte Carlo simulations and density functional theory. Special attention is devoted to the solvation force and its dependence on the nature of the solvent-solvent and solvent-surface interactions. LÄS MER

  5. 4. Structure-Reactivity Correlations for Reactions of Palladium(II) and Platinum(IV) Complexes

    Författare :Tiesheng Shi; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thiol; l-methionine; maleic acid; carboxylic acid; thioether; platinum IV ; palladium II ; linear free energy relationship; volumes of activation; structure-reactivity correlation; reduction; substitution; equilibria; kinetics; mechanism; glutathione; Animal physiology; Djurfysiologi;

    Sammanfattning : The kinetics and mechanism for substitution reactions on tetraaquapalladium(II) by an extended series of thioethers, a great number of carboxylic acids, and olefins have been studied by use of UV-VIS, stopped-flow, and high-pressure stopped-flow spectrophotometry and NMR spectroscopy. Second-order rate constants k and activation parameters (activation enthalpies, entropies, and volumes) for formation of monodentate 1:1 complexes have been determined. LÄS MER

  7. 5. Studies of Steel/Slag Equilibria using Computational Thermodynamics

    Författare :Lina Kjellqvist; Bo Sundman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel slag equilibria; thermodynamic modelling; thermodynamic assessment; CALPHAD; phase diagram; Thermo-Calc; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : The main focus in the present work concerns calculations on steel/slag equilibria. Thermodynamic software and databases are now powerful and accurate enough to give reliable results when applied to complex metallurgical processes. One example is the decarburization process of high alloyed steels. LÄS MER
