Stick‐Slip Tremor Beneath an Alpine Glacier
(Geophysical Research Letters, 2021-01-25)Sliding of glacial ice over its base is typically described by a frictionless or slowly deforming bed. This view is challenged by recent seismic observations of stick‐slip motion at the ice‐bed interface. We revisit a ... -
Stochastic cosmological inflation - a replica field-theoretical study
(Univ. Bielefeld, 2009)In this thesis we apply methods from statistical physics to stochastic inflation. Those methods, the replica field theory and the Gaussian variational methods, have to our knowledge never been applied before in this context, ... -
Stochastic Eulerian model for the flow simulation in porous media
(WIAS, Berlin2003)This work deals with the stochastic flow simulation in statistically isotropic and anisotropic saturated porous media in 3D case. The hydraulic conductivity is assumed to be a random field with lognormal distribution. Under ... -
Stochastic flow simulation and particle transport in a 2D layer of random porous medium
(WIAS, Berlin2008)A stochastic numerical method is developed for simulation of flows and particle transport in a 2D layer of porous medium. The hydraulic conductivity is assumed to be a random field of a given statistical structure, the ... -
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 ... -
Stochastic Modeling Approach to Identify Uncertainties of Karst Conduit Networks in Carbonate Aquifers
(Water Resources Research, 2022-08-09)The characterization of the karst conduit network is an essential task to understand the complex flow system within karst aquifers. However, this task is challenging and often associated with uncertainty. Equivalent porous ... -
Stochastische Geschwindigkeitsfelder in der expandierenden Hülle entwickelter Sterne
(Univ. Hamburg, 2004)Die physikalischen Ursachen für das Auftreten massiver Winde bei entwickelten Sternen sind weitgehend unverstanden. Aus diesem Grund ist es bisher noch nicht gelungen, von einer empirischen Beschreibung des Phänomens zu ... -
Stochastische Grundwassermodellierung in der ingenieurtechnischen Praxis
(Sörensen, Hamburg, 1997)Analytische und numerische Modelle sind seit Jahrzehnten bewährte Hilfsmittel zur Berechnung von Strömungs- und Transportvorgängen im Grundwasser. Mit der Verfügbarkeit leistungsstarker Kleinrechner seit den 80er Jahren ... -
Stollenordnung für Göllnitz 1498
(1498)Diese Im Stadtbuch von Göllnitz (Gelnica) unter dem Jahr 1498 eingetragene Stollenordnung für Göllnitz geht auf eine ältere Stollenordnung zurück. Sie wurde anlässlich einer am 5. Oktober 1498 auf Antrag des Kanzlers des ... -
Storm Event–Driven Occurrence and Transport of Dissolved and Sorbed Organic Micropollutants and Associated Effects in the Ammer River, Southwestern Germany
(Environmental Toxicology and Chemistry, 2020-11-30)Storm events lead to agricultural and urban runoff, to mobilization of contaminated particulate matter, and to input from combined sewer overflows into rivers. We conducted time‐resolved sampling during a storm event at ... -
Storm-induced turbulence alters shelf sea vertical fluxes
(Limnology and Oceanography Letters, 2020)Storms are infrequent, intense, physical forcing events that represent a potentially significant driver of ocean ecosystems. The objective of this study was to assess changes in water column structure and turbulent fluxes ... -
Strahlungsemission in einem thermischen Hintergrundplasma in den Jets Aktiver Galaxienkerne
(Univ. Bochum, 2004)Die vorliegende Arbeit untersucht den Einfluß von thermisch verteiltem Plasma auf die Strahlungsemission in den Jets von aktiven galaktischen Kernen. Zur Bestimmung der Heiz- und Strahlungsproduktionsraten wird die ... -
Strain Localisation, Fracturing and Hydrothermal Mineralisation: Numerical Models of the Mount Isa Copper Deposit, Australia
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006)There is substantial need in mineral exploration to understand the structural controls on ore deposition for these types of deposits in order to predict the localities of new ones. Application of basic principles of rock ... -
Strain migration during multiphase extension, Stord Basin, northern North Sea rift
(Basin Research, 2020-11-11)In regions experiencing multiple phases of extension, rift‐related strain can vary along and across the basin during and between each phase, and the location of maximum extension can differ between the rift phase. Despite ... -
Strain Rate-Dependent Hardening-Softening Characteristics of Gas Hydrate-Bearing Sediments
(Geochemistry, Geophysics, Geosystems, 2019)The presence of gas hydrates (GHs) increases the stiffness and strength of marine sediments. In elasto-plastic constitutive models, it is common to consider GH saturation (Sh) as key internal variable for defining the ... -
Strain Signals Governed by Frictional‐Elastoplastic Interaction of the Upper Plate and Shallow Subduction Megathrust Interface Over Seismic Cycles
(Tectonics, 2022-05-03)The behavior of the shallow portion of the subduction zone, which generates the largest earthquakes and devastating tsunamis, is still insufficiently constrained. Monitoring only a fraction of a single megathrust earthquake ... -
Strain-dependent slope stability
(Acta Geotechnica, 2020-05-09)The state of equilibrium of a slope is usually interpreted and expressed by safety factors based on calculations with limit equilibrium methods. Different stress states, failure modes and hydraulic conditions in sections ... -
Strategien und Konfliktvermeidung bei der Restaurierung von Niedermooren unter Gewässer-, Klima- und Naturschutzaspekten, dargestellt am Beispiel des nordostdeutschen Tieflandes
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Beiheft 4; 2011)Abstract: The long-term goals of fen restoration include climate, water, and natural areas protection. Depending on the characteristics of fen under consideration (size, landscape position, previous land use, current ...
