Analyse von Bathymetrie und akustischer Rückstreuung verschiedener Fächersonar- und Sedimentecholot-Systeme zur Charakterisierung und Klassifizierung des Meeresbodens am Gakkel-Rücken, Arktischer Ozean
(Univ. Bremen, 2008)
Im ersten Kapitel erfolgt nach der Zielsetzung und Motivation für die vorliegende Dissertation eine kurze geographische Beschreibung des Arktischen Ozeans und dessen tektonischer Entwicklung.Das Augenmerk gilt dabei dem ...
Frontale Akkretion und Verformungsaufteilung eines gebogenen Falten- und Überschiebungsgürtels
(GFZ, Helmholtz-Zentrum, 2001)
Source processes and spectral ground motion models of intermediate depth Vrancea (Romania) earthquakes
(Univ. Karlsruhe, 2007)
For successful assessment and mitigation of earthquake hazards, it is necessary to be able to reliably predict the level of ground shaking which has to be expected from future large earthquakes. This prediction of ground ...
Satellite to satellite tracking in the space-wise approach
(Univ. Stuttgart, 2006)
The launch of the champ mission in 2000 has renewed interest in the recovery of the geopotential field from satellite observations which has been a challenging research issue for decades. It was the first dedicated gravity ...
Physical and chemical constraints on core-mantle differentiation in terrestrial planets
(Univ. Bayreuth, 2008)
In this study a physical mechanism and geochemical parameters have been examined in high pressure and high temperature experiments in order to place constraints on the conditions and the manner by which core-mantle ...
Broadband IF circuits for superconductor isolator superconductor (SIS) mixers for the Heterodyne Instrument for the far infrared on the Herschel Space Observatory and for sideband separating mixers
(Univ. Köln, 2007)
This thesis describes the development and manufacturing of the IF circuits for two different heterodyne receivers used for sub-mm radio astronomy. The first project is the broadband 4-8 GHz IF circuitry for the mixer units ...
