  2. 1. Distance Protection of Transmission Lines with High Levels of Series Compensation : A study on frequency and time domain communication independent distance protection for series compensated lines

    Author : Md Tanbhir Hoq; Nathaniel Taylor; Jianping Wang; Claus Leth Bak; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Series capacitor; Series compensation; Transmission line; Distance protection; Incremental quantity; Lissajous curve; RL model; RLC model; Seriekondensator; Seriekompensation; Transmissionslinje; Distansskydd; Inkrementell kvantitet; Lissajous-kurva; RL-modell; RLC-modell; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Series capacitors are used in electric transmission lines to increase their power transfer capacity. They compensate for the inductive reactance of the line. They offer a useful alternative to building new lines, in view of economic and environmental constraints. READ MORE

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

    Author : Maria Jansson; Beräkningskemi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Interactions in aqueous salt solutions : Atomistic modelling versus experiment

    Author : Vidar Aspelin; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistisk mekanik; molekylär modellering; MD simuleringar; MC simuleringar; statistical mechanics; molecular simulation; MD simulations; MC simulations; Kirkwood-Buff theory; Hofmeister series;

    Abstract : The research in this thesis investigates how atoms and molecules constituting aqueous salt solutions interact using computational approaches, namely Monte Carlo simulations and molecular dynamics simulations. In the first paper, an atomistic model was developed for aqueous solutions of sodium thiocyanate and potassium thiocyanate (NaSCN and KSCN). READ MORE

  6. 4. Electrostatically Driven Structure Formation in Clay Dispersions

    Author : Maria Jansson; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Laponite®; Taktoid; Anisotropi; Överladdning; Interkalering; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; zeta-potential; Clay; Montmorillonite; Laponite®; Nanoplatelets; Tactoid; Anisotropy; Overcharging; Intercalation; Coarse-grained modeling; MD simulations; MC simulations; SAXS; Swelling pressure; zeta-potential;

    Abstract : Clay minerals consist of clay platelets, which are anisotropic in both size and charge, and these can form a lamellar structure depending on the size, making it a seemingly perfect model system for an electrical double layer. The situation is however, from a structural point, slightly less ideal. READ MORE

  7. 5. Small and Large, Charged Molecules in Solution and at Interfaces

    Author : Giulio Tesei; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular modeling; MD simulations; statistical mechanics; SAXS; QCM-D; Hofmeister series; amyloid fibril; lipid bilayer; cell-penetrating peptide; molekylär modellering; MD simuleringar; MC simuleringar; statistisk mekanik; SAXS; QCM-D; amyloidfibriller; cellmembran; cellpenetrerande peptider;

    Abstract : The influence of small and large, charged molecules on the properties of aqueous interfaces has important implications in chemistry, biology, and medicine. For example, at the surface of marine aerosols, the presence of halide anions and tropospheric gases gives way to multiphase chemical reactions affecting climate and air quality. READ MORE
