  1. 6. Decision processes in discretionary long-range travel

    Författare :Christer Lindh; KTH; []
    Nyckelord :;

    Sammanfattning : The present study is founded in transportation research but is interdisciplinary in that it is drawing on research areas like consumer behaviour, cognitive science, economic psychology and marketing. The results will provide knowledge to 1) researchers, who need a deeper understanding of travel behaviour in order to develop better models, 2) policy makers, who need information on transport demand for planning the infrastructure and for evaluating environmental consequences and 3) marketing analysts, who need information on the whole complex of business and discretionary travel pattems.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous underwater vehicles; Underwater gliders; Propulsion; Fuel cell; Energy management strategies; Autonom undervattensfarkost; Undervattensglidning; Propulsion; Bränslecell; Energy Management Strategies; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Autonomous underwater vehicles (AUVs) are robotic platforms that are commonly used to gather environmental data, provide bathymetric images, and perform manipulation tasks. These robots are used not only for scientific, but also for industrial and military purposes. LÄS MER

  4. 8. First-principles calculations of long-range intermolecular dispersion forces

    Författare :Auayporn Jiemchooroj; Bo E. Sernelius; Irina Yakimenko; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; van der Waals forces; dispersion forces; intermolecular interactions; dispersion coefficients; polarizability; Physics; Fysik;

    Sammanfattning : This work presents first-principles calculations of long-range intermolecular dispersion energies between two atoms or molecules as expressed in terms of the C6 dipole-dipole dispersion coefficients. In a series of publications, it has been shown by us that the complex linear polarization propagator method provides accurate ab initio and first-principles density functional theory values of the C6 dispersion coefficients in comparison with those reported in the literature.

  7. 10. Spectra and Dynamics of Excitations in Long-Range Correlated Structures

    Författare :Lars Kroon; Rolf Riklund; Magnus Johansson; Jeroen Lamb; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quasicrystals; deterministic aperiodic superlattices; Markov chains; electronic structure and diffusion; elastic vibrations; Fraunhofer diffraction; discrete solitons; phase transitions; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : Vad karaktäriserar en kristall? Svaret på denna till synes enkla fråga blir kanske att det är en anordning av atomer uppradade i periodiska mönster. Så ordnade strukturer kan studeras genom att det uppträder så kallade Braggtoppar i röntgendiffraktionsmönstret. LÄS MER
