  1. 11. Seismic tomography : Inversion for P- and S-wave velocities

    Författare :Ari Tryggvason; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : Seismology is undoubtedly the most powerful method for determining the structure of the Earth below the deepest borehole. This thesis describes the, use of seismic signals from both man-made and earthquake sources to model seismic velocities within a volume of the Earth. LÄS MER

  3. 12. Of Pipes and Bends

    Författare :Jacopo Canton; Philipp Schlatter; Ramis Örlü; Dwight Barkley; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear instability; bifurcation; flow control; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : This work is concerned with the transition to turbulence of the flow in bent pipes, but it also includes an analysis of large-scale turbulent structures and their use for flow control.The flow in a toroidal pipe is selected as it represents the common asymptotic limit between spatially developing and helical pipes.
