  • Tunnel Health Monitoring Using Seismics 
    Gebre, Mesay Geletu (Master thesis / Masteroppgave, 2013)
    In this thesis a new approach, called THEAMTM, is presented. The THEAMTM methodology is a non-invasive tunnel health monitoring method using active seismic. The method incorporates geophysical seismic analysis methods and ...
  • Tunneling times of single photons 
    Gulla, Jan; Skaar, Johannes (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)
    Although the group delay of classical pulses through a barrier may suggest superluminality, the information transfer is limited by the precursor, which propagates at the vacuum light speed. Single photons, however, have ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The description of the local turbulent energy transfer and the high-resolution ion distributions measured by the Magnetospheric Multiscale mission together provide a formidable tool to explore the cross-scale connection ...
  • Turbulent Flow Past An Edged GeometryBegrenset tilgang 
    Langmoen, Jacob Teodor Staffansson (Master thesis / Masteroppgave, 2023)
    Vortexes are a major part of turbulence studies, and have dominating effect on aerodynamics. Vortex generators have been used for a long time on air-crafts, to delay flow separation and increase performance. In this study, ...
  • Turbulente flukser ved reversert skjær i den geostrofiske vinden 
    Simonsen, Magne (Master thesis / Masteroppgave, 2010)
    In boundary layer modelling, the Monin-Obukhov theory is widely used to parmeterize the wind profiles and the momentum fluxes. During the IPY-THORPEX campaign at Andøya at 3. March 2008, a flight was made across an arctic ...

  • Turnaround radius in ΛCDM and dark matter cosmologies with shear and vorticity 
    Del Popolo, Antonino; Chan, Man Ho; Mota, David (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    We determine the relationship between the turnaround radius, Rt, and mass, Mt, in Λ CDM , and in dark energy scenarios, using an extended spherical collapse model taking into account the effects of shear and vorticity. We ...
  • Turning off autophagy: Investigation of the role of TOR and the Ubiquitin Proteasome System.Begrenset tilgang
