  1. 1. My first-passage target search in physics and biology

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Markus Nyberg; Umeå universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; first-passage; mean first-passage time; mean first-arrival time; random walk; diffusion; zero-crossing; persistence; survival probability; network; resetting; teoretisk fysik; Theoretical Physics;

    Sammanfattning : Random walks and diffusing particles have been a corner stone in modelling the random motion of a varying quantity with applications spanning over many research fields. And in most of the applications one can ask a question related to when something happened for the first time. That is, a first-passage problem. LÄS MER

    Sammanfattning : Shyness as a behavioral characteristic has been in focus of research in psychology for a number of decades. Adolescent shyness has, however, been relatively overlooked compared with studies conducted on children and adults. LÄS MER

  5. 5. Polar molecules in crystalline and surface environments : From first principles

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Alfredsson; Uppsala universitet.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : With the knowledge of the composition and structure of a chemical system, be it a molecule, a two-dimensional surface or a three-dimensional crystal, it is now possible to predict the specific properties of the compound under consideration via computational studies. Molecular and periodic Hartree-Fock and DFT calculations have been used as a tool to study polar molecules and how their properties respond to the molecular environment in a crystal or on an ionic surface.
