  1. 1. Urban microclimate and surface hydrometeorological processes

    Författare :Christer Jansson; Per-Erik Jansson; David Gustafsson; Chen Delian; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CoupModel; ENVI-met; roughness sub-layer; urban heat island; Physical geography; Naturgeografi;

    Sammanfattning : The urban near surface atmosphere is of great concern since it affects the climate to which an increasing amount of people are immediately exposed. This study investigated the microclimate in central Stockholm in terms of the thermal conditions in the 0-2. LÄS MER

  5. 4. Reduction of finite-group representations and influence of lattice symmetry on some properties in condensed-matter physics

    Författare :Per-Olof Jansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The first part of this thesis describes a method for calculating irreducible matrix representatives of arbitrary finite groups. Using a projection operator technique, a problem of degeneracy in the eigenvalues appear. By using a linear combination of irreducible group representatives the degeneracy is shown to be removed.

  7. 5. Rough Scatterers in Acoustics and Elastodynamics

    Författare :Per-Åke Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic scattering; penny-shaped crack; rough surfaces; elastodynamic scattering; T matrix; null field approach;

    Sammanfattning : The purpose of this thesis is to investigate the influence of roughness on wave scattering from finite-sized surfaces, in particular elastic wave scattering from cracks. Acoustic scattering from a sphere is considered using the null field approach. LÄS MER
