Sammanfattning : This thesis, consisting of three papers and a summary, studies topics in the theory of stochastic processes related to long-range dependence. Much recent interest in such probabilistic models has its origin in measurements of Internet traffic data, where typical characteristics of long memory have been observed. LÄS MER

Sammanfattning : Ab initio alloy theory, formulated within the exact muffin-tin orbitals method in combination with the coherent-potential approximation, is used to determine the effect of long range order on the elastic properties. The lattice parameters and single-crystal elastic constants of Cu3Au are calculated for different partially ordered structures ranging from the fully ordered L12 to the random face centered cubic lattice.

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.

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.
