Für Zwecke der differentiellen astrometrischen Positionsbestimmung von Kleinplaneten werden heutzutage verbreitet CCD-Beobachtungen eingesetzt. Insbesondere im Rahmen von Follow-up-Beobachtungsprogrammen sind eine Vielzahl ...

This thesis had two primary objectives: One objective was to explore and develop applications of Fourier transform infrared spectroscopy (FTIRS) for the quantification of biogeochemical properties in lake sediment; the ...

In der vorliegenden Arbeit wird die Heizung des interstellaren Mediums durch die Dämpfung von Plasmawellenturbulenz untersucht. Es wird gezeigt, daß die Heizung ausreicht, das thermische Gleichgewicht im interstellaren ...

Coronal Mass Ejections (CMEs) are extremely dynamical and huge events in which the solar plasma, initially contained in closed coronal magnetic field lines, is ejected into interplanetary space. When a CME is detected ...

The aim of this thesis is to obtain as much information as possible, about global solutions of the Cauchy problem for the Einstein-Vlasov-scalar field system with spherical, plane and hyberbolic symmetries written in areal ...

We combine numerical modeling of lithospheric extension with analysis of seismic moment release and earthquake b-value in order to elucidate the mechanism for deep crustal seismicity and seismic swarms in the Main Ethiopian ...

After the epoch of reionisation the intergalactic medium (IGM) is kept at a high photoionisation level by the cosmic UV background radiation field. Primarily composed of the integrated contribution of quasars and young ...

Gegenstand der vorliegenden Arbeit ist die technische Weiterentwicklung des durchstimmbaren Infrarot-Heterodynsystems THIS (Tuneable Heterodyne Infrared Spectrometer) sowie die Planung, Vorbereitung und Durchführung diverser ...

This thesis discusses the relation between the energetic particle characteristics measured by Galileo in the inner to middle Jovian magnetosphere, and the auroral emissions observed by the Hubble Space Telescope. The thesis ...

A new stochastic fractal model based on a fractional Laplace equation is developed. Exact representation for the spectral and correlation functions under random boundary excitation are obtained. Randomized spectral expansion ...
