Tropical precipitation influencing boreal winter midlatitude blocking
(
- Atmospheric Science Letters
, 2019)
Recent studies using reanalysis data and complex models suggest that the Tropics influence midlatitude blocking. Here, the influence of tropical precipitation anomalies is investigated further using a dry dynamical model ...
Numerical analysis of the interaction between rockbolts and rock mass for coal mine drifts in Vietnam
(Univ. Freiberg (Sachsen), 2008)
Since decades rockbolts are widely used as a support measure in mining and civil engineering. The presented literature review under special consideration of the situation in underground Vietnamese coal mines has revealed ...
Neue Möglichkeiten interaktiver 3-dimensionaler Modellierungen von Potentialfeldern und ihrer Ableitungen
(
- Frühjahrstagung 2015 "Versorgungssicherheit, Umwelt, Wettbewerbsfähigkeit - Welchen Beitrag leistet die E&P-Industrie?
, 2015-04-22)
Die hier dargestellten Methoden dienen der drei-dimensionalen, interaktiven Bearbeitung der Potentialfelder Gravimetrie und Magnetik, sowie ihrer Ableitungen (Schwere- und Magnetik-Tensor). Die Methodik ist sowohl für ...
Möglichkeiten und Grenzen der Hill-Gleichungen für die Schwerefeldbestimmung
(GFZ, Helmholtz-Zentrum, 2006)
Development of a novel balloon-borne optical sonde for the measurement of ozone and other stratospheric trace gases
(Univ. Bremen, 2005)
Ozone, balloon-borne measurements, atmospheric trace gases, concentration profiles, climate change. - In the frame of this work, a new small-size balloon-borne sonde was developed. A miniature grating spectrometer in the ...
A Thermo‐Compositional Model of the Cratonic Lithosphere of South America
(
- Geochemistry, Geophysics, Geosystems
, 2021-04-22)
New seismic data on the crust and upper mantle of South America have recently become available and describe its deep structure with unprecedented resolution. Here, seismic data are combined with gravity data and mineral ...
Stochastic flow simulation in 3D porous media
(2005)
Stochastic models and Monte Carlo algorithms for simulation of flow through porous media beyond the small hydraulic conductivity fluctuation assumptions are developed. The hydraulic conductivity is modelled as an isotropic ...
Nowcasting and Predicting the Kp Index Using Historical Values and Real-Time Observations
(
- Space Weather
, 2019)
Current algorithms for the real-time prediction of the Kp index use a combination of models empirically driven by solar wind measurements at the L1 Lagrange point and historical values of the index. In this study, we explore ...
A modified Mask region‐based convolutional neural network approach for the automated detection of archaeological sites on high‐resolution light detection and ranging‐derived digital elevation models in the North German Lowland
(
- Archaeological Prospection
, 2021-02-02)
Due to complicated backgrounds and unclear target orientation, automated object detection is difficult in the field of archaeology. Most of the current convolutional neural network (CNN) object‐oriented detection techniques ...
Die visuelle Interpretation von Fernerkundungsdaten
(TU Bergakademie Freiberg, Fakultät Geowissenschaften, Geotechnik und Bergbau, Freiberg <Sachsen>, 2008)
Die Fähigkeit, in Luft- und Satellitenbildern Objekte wiederzuerkennen, kann folgendermaßen erklärt werden: Aus der Kenntnis einer Landschaft und ihrer Abbildung im Bild werden Interpretationsregeln entwickelt, die bestimmten ...
