Computation of multivalued traveltimes in three-dimensional heterogeneous media
(Univ. Hamburg, 2003)In this thesis, I propose several methods for an efficient computation of 2D and 3D traveltimes of transmitted waves in smooth media. Traveltimes are needed in several seismic processing methods such as Kirchhoff prestack ... -
Computational methods for the analysis of climate change communication: Towards an integrative and reflexive approach
; (Wiley Interdisciplinary Reviews: Climate Change, 2022-11-05)
Computational methods, in particular text‐as‐data or Natural Language Processing (NLP) approaches, have become popular to study climate change communication as a global and large‐scale phenomenon. Scholars have discussed ... -
Computational Modelling of Coupled Heat Transport between the Heterogeneous Earth and an Overlying Ice Sheet
Bodenburg, Sascha;; Blachut, Wojciech; ; (2021)
Due to a complex interplay between the Earth and overlying ice sheets, a large variety of subglacial landforms developed. One example is the in the North German Basin widely spread phenomenon of tunnel valleys. An observed ... -
Computerauswertung von Seespiegeldaten für das IGCP—Projekt Nr. 61
(E&G – Quaternary Science Journal; Vol.30, No. 1)Ein Teil des deutschen Beitrages zum IGCP Sea Level Project war die Computerauswertung von Seespiegeldaten. Dies umfaßte den Entwurf eines Formblattes für die Datenerfassung sowie die Entwicklung eines Computerprogrammsystems ... -
Computing the biomass potentials for maize and two alternative energy crops, triticale and cup plant (Silphium perfoliatum L.), with the crop model BioSTAR in the region of Hannover (Germany)
(Environmental Sciences Europe, 2014)Background Lower Saxony (Germany) has the highest installed electric capacity from biogas in Germany. Most of this electricity is generated with maize. Reasons for this are the high yields and the economic incentive. ... -
Concepts and models for the characterization of the West Gedaref hydrogeologic system, Sudan

Concepts for nondestructive and depth‐resolved X‐ray residual stress analysis in the near‐surface region of nearly single crystalline materials with mosaic structure
(Journal of Applied Crystallography, 2020-12-02)Two evaluation concepts for nondestructive depth‐resolved X‐ray residual stress analysis in the near‐surface region of materials with cubic symmetry and nearly single crystalline structure are introduced by simulated ... -
Conch geometry, ontogeny and dimorphism in the Early Bajocian ammonoid Stephanoceras from Normandy, France
; (Lethaia, 2021-07-22)
A large suite of specimens belonging to the Early Bajocian Stephanoceras from Évrecy (Normandy, France) displays wide variation in conch and sculpture. The quantitative analysis of the conch geometry and its ontogeny on ... -
Concretionary methane-seep carbonates and associated microbial communities in Black Sea sediments
; Peckmann, J.; Blumenberg, M.; Michaelis, W.; Reimer, A.; (Palaeogeography, Palaeoclimatology, Palaeoecology, 2005)
Gas seeps in the euxinic northwestern Black Sea provide an excellent opportunity to study anaerobic, methane-based ecosystems with minimum interference from oxygen-dependent processes. An integrated approach using fluorescence- ... -
Cone penetration tests in dry and saturated Ticino sand
; ; ; ; ; (Bulletin of Engineering Geology and the Environment, 2021-03-11)
It is commonly assumed that dry and saturated sands exhibit similar cone resistance–relative density relationships. Some studies pointed out that partial saturation and calcareous sands with considerable fines content are ... -
Confinement and anisotropy of ultrahigh-energy cosmic rays in isotropic plasma wave turbulence
(Univ. Bochum, 2007)We have investigated the implications of isotropically distributed interstellar magnetohydrodynamic plasma waves on the scattering mean free path and the spatial anisotropy of high-energy cosmic rays. We demonstrate a ... -
Conjugation of artificial humic acids with inorganic soil matter to restore land for improved conservation of water and nutrients
; ; ; (Land Degradation & Development, 2019)
Artificial soil (AS) with a dark–brown appearance and high soil organic matter (SOM) was manufactured under hydrothermal conditions from poor sandy landfill using the 'hydrothermal humification process.' This approach may ... -
Consequences of land-use change and the wildfire disaster of 2017 for the central Chilean biodiversity hotspot
; ; ; (Regional Environmental Change, 2021-03-25)
Central Chile is an important biodiversity hotspot in Latin America. Biodiversity hotspots are characterised by a high number of endemic species cooccurring with a high level of anthropogenic pressure. In central Chile, ... -
Consequences of regularizing the Sawyer–Eliassen equation in balance models for tropical cyclone behaviour
; (Quarterly Journal of the Royal Meteorological Society, 2019)
The consequences of regularizing the Sawyer–Eliassen equation to calculate the stream function for the axisymmetric secondary circulation of a tropical cyclone are explored. Regularization is an ad hoc procedure in which ... -
Considering different recent advancements in GNSS on real-time zenith troposphere estimates
; ; (GPS Solutions, 2020-07-30)
Global navigation satellite system (GNSS) remote sensing of the troposphere, called GNSS meteorology, is already a well-established tool in post-processing applications. Real-time GNSS meteorology has been possible since ... -
