Investigating the potential of hyperspectral remote sensing data for the analysis of urban imperviousness
(Univ. Berlin, 2008)
Durch den Prozess der Urbanisierung verändert die Menschheit die Erdoberfläche in großem Ausmaß und auf unwiederbringliche Weise. Die optische Fernerkundung ist eine Art der Erdbeobachtung, die das Verständnis dieses ...
Drag and drop of pores during grain boundary migration
(Univ. Bochum, 2006)
Untersucht werden die Wechselwirkungen zwischen Poren und Korngrenzen in Polykristallen, insbesondere das Ziehen einer Pore mit und die Separation einer Pore von einer wandernden Korngrenze. Zwei relevante Transportmechanismen ...
Ein neues magmatisch-tektonisches Modell zur Asthenosphärendynamik im Bereich der zentralandinen Subduktionszone Südamerikas
(Univ. Potsdam, 2008)
Im Rahmen der Dissertation wurden an Wässern und freien Gasen aus Thermalquellen sowie an weniger als 5 Millionen Jahre alten basischen Vulkaniten des zentralandinen Puna-Hochplateaus (NE-Argentinien) umfangreiche element- ...
Seismic imaging in complex media with the common reflection surface stack
(Univ. Hamburg, 2009)
Reflection seismic is one of the most commonly used geophysical method for the oil and gas exploration. In this thesis I show the application of the Common Reflection Surface (CRS) stack technique to improve the quality ...
MHD-Modellierung der Dynamik der solaren Korona
(Univ. Bochum, 2005)
Gegenstand der Arbeit ist die Entwicklung eines symmetriefreien magnetohydrodynamischen Modells der solaren Korona, welches sich vor allem durch seine explizite Energiegleichung von bestehenden Ansätzen abhebt. Die relevanten ...
Cable reverberations during wireline distributed acoustic sensing measurements: their nature and methods for elimination
(
- Geophysical Prospecting
, 2021-05-16)
The application of distributed acoustic sensing in borehole measurements allows for the use of fibre optic cables to measure strain. This is more efficient in terms of time and costs compared with the deploying of conventional ...
Potential for Early Forecast of Moroccan Wheat Yields Based on Climatic Drivers
(
- Geophysical Research Letters
, 2020)
Wheat production plays an important role in Morocco. Current wheat forecast systems use weather and vegetation data during the crop growing phase, thus limiting the earliest possible release date to early spring. However, ...
Investigation of the dwarf galaxy population in Hickson compact groups
(Univ. Bochum, 2003)
The nature of compact galaxy groups, which is important concerning the influence of the environment on member galaxies, is largely unknown. In this work dwarf galaxies are investigated in the outer regions of compact galaxy ...
Step-on versus step-off signals in time-domain controlled source electromagnetic methods using a grounded electric dipole
(
- Geophysical Prospecting
, 2020)
The time-domain controlled source electromagnetic method is a geophysical prospecting tool applied to image the subsurface resistivity distribution on land and in the marine environment. In its most general set-up, a ...
The Impact on the Ozone Layer of a Potential Fleet of Civil Hypersonic Aircraft
(
- Earth's Future
, 2020)
The aeronautical community is currently researching technology that might lead to commercial hypersonic aircraft that would cruise at Mach 5–8 in the middle or upper stratosphere and would transfer passengers from London ...
