Skalenvarianz hydraulischer und struktureller Eigenschaften geklüfteter Gesteine
(Techn. Univ. Berlin, 2007)
Pressure‐Driven Poiseuille Flow Inherited From Mesozoic Mantle Circulation Led to the Eocene Separation of Australia and Antarctica
(
- Journal of Geophysical Research: Solid Earth
, 2021-04-27)
The separation between Australia and Antarctica occurred during the final stages of the break‐up of Pangea. Reconstructions of the rifting of the Australian plate away from Antarctica show fast spreading rates since ...
Influence of the surface on the atmospheric circulation of Mars
(Univ. Zugl.: Braunschweig, 2007)
Unlike on Earth where 3/4 of the surface is covered by oceans, the Martian surface has rougher topography with greater magnitudes of mountains and valleys. The Martian atmosphere is less dense compared to the terrestrial ...
Stability of flat galaxies
(2008)
In this thesis we investigate the existence and properties of stationary solutions of the flat Vlasov-Poisson system. This system of partial differential equations can be used as a model of extremely flat astronomical ...
Convergence of Daily GRACE Solutions and Models of Submonthly Ocean Bottom Pressure Variability
(
- Journal of Geophysical Research: Oceans
, 2021-02-19)
Knowledge of submonthly variability in ocean bottom pressure (pb) is an essential element in space‐geodetic analyses and global gravity field research. Estimates of these mass changes are typically drawn from numerical ...
Sand dunes on mars and on earth
(Univ. Stuttgart, 2007)
In this work the dune model introduced by Sauermann et al. (2001) is extended and applied to investigate the formation of different dune shapes on Mars and on Earth as function of wind directionality and sand availability. ...
Measurement of the proton air cross section using hybrid data of the Pierre Auger Observatory
(Univ. Karlsruhe, 2008)
Non-analytical line profiles in stellar atmospheres
(Univ. Hamburg, 2008)
In this work, nonanalytical line profiles for both cool and hot, dense atmospheres are added to the opacity calculations of the multipurpose stellar atmosphere code PHOENIX. Their influence on model atmospheres and synthetic ...
Georadar for small-scale high-resolution dielectric property and water content determination of soils
(Univ. Berlin, 2007)
To understand processes and dynamics linked to the volumetric water content of soils thorough knowledge of the water distribution inside soils is required. The applicability of the georadar technique for small scale soil ...
Spectral mixture analysis for monitoring and mapping desertification processes in semi-arid areas in North Kordofan State, Sudan
(Univ. Dresden, 2007)
One of the most important recently issues facing Sudan as well as sub-Sahara Africa is the threat of continued land degradation and desertification, as result of climatic factors and human activities. Remote sensing and ...
