  1. 6. High resolution time-frequency representations

    Författare :Isabella Reinhold; Statistical Signal Processing Group; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; time-frequency analysis; non-stationary signals; multi-component signals; IF estimation; reassignment;

    Sammanfattning : Non-stationary signals are very common in nature, e.g. sound waves such as human speech, bird song and music. It is usually meaningful to describe a signal in terms of time and frequency. LÄS MER

  5. 9. On the representation of precipitation in high-resolution regional climate models

    Författare :Petter Lind; Erik Kjellström; Michael Tjernström; Jan Erik Haugen; Anna Rutgersson; Abdel Hannachi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Regional climate modeling; high-resolution; convection parameterization; precipitation; extremes; statistical analysis; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography; meteorologi; Meteorology;

    Sammanfattning : Weather and climate models applied with sufficiently fine mesh grids to enable a large part of atmospheric deep convection to be explicitly resolved have shown a significantly improved representation of local, short-duration and intense precipitation events compared to coarser scale models. In this thesis, two studies are presented aimed at exploring the dependence of horizontal resolution and of parameterization of convection on the simulation of precipitation. LÄS MER

  7. 10. High-Resolution Seismics Methods Applied to Till Covered Hard Rock Environments

    Författare :Björn Bergman; Christopher Juhlin; Laust Börsting Pedersen; Ari Tryggvason; Ramon Carbonell; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; High-Resolution; Reflection Seismics; Tomography; Nuclear waste repository; Bedrock; Sediments; Geofysik; Geophysics; Geofysik;

    Sammanfattning : Reflection seismic and seismic tomography methods can be used to image the upper kilometer of hard bedrock and the loose unconsolidated sediments covering it. Developments of these two methods and their application, as well as identifying issues concerning their usage, are the main focus of the thesis. LÄS MER
