-
(2006)Point and line singularities are superposed with incident unidirectional saturated and unsaturated flows. The resulting isobars of 3D Laplacian or advective dispersion equation fields model either seepage face dimples and ...
-
(2001)Methods of prevention of sudden outbursts have been considered. It has been shown that preliminary degassing of coal seams with the use of hydraulic separation of them is efficient method. Mathematical model of process of ...
-
(2001)Real rock is non-uniform solid body. Non-uniformity of the rock is determined by presence of pores, microcracks etc. Recurrence formulae have been offered for probabilities, describing simulation model of kinetic process ...
-
(2001)Some plates deform across zones that are many hundreds to thousands of kilometres wide, much broader than traditional boundaries such as mid-ocean ridges, deep-sea trenches and oceanic transform faults, across which most ...
-
(2002)We investigate the analytic signal method and its applicability in obtaining source locations of compact environmental magnetic objects. Previous investigations have shown that, for two-dimensional magnetic sources, the ...
-
(2002)One-dimensional analytical porosity-weighted solutions of the dual-porosity model are derived, providing insights on how to relate exchange and storage coefficients to the volumetric density of the high-permeability medium. ...
-
(2003)We investigate the resolution of band‐limited seismic signals using analytical arguments, based on the Rytov approximation of the single scattering problem and numerical modeling of the full wave equation. The experimental ...
-
(2006)Based on cusp-type catastrophe theory, a sample rock–rock model for studying the pillar rockburst mechanism is presented in this paper. It is shown that the stiffness ratio, K, of the roof and floor to the pillar plays an ...
-
(2006)Decades of work have shown that trace- to minor-amounts of hydrous components commonly occur in minerals whose chemical formula would be normally written without any hydrogen, namely, the nominally anhydrous minerals (NAMs). ...
-
ANALYTICAL MODELLING OF THE FORMATION TEMPERATURE STABILIZATION DURING THE BOREHOLE SHUT-IN PERIOD (2003)The problem of formation temperature stabilization during the shut-in period is solved analytically by the approximate generalized integral-balance method. The model accounts for the thermal history of the borehole ...
-
(2001)We study the early stages of diapirism and analyse the gravitational and buckling instabilities of a buoyant viscous layer overlain by a layer of strongly non-Newtonian power-law rheology (when a power-law exponent tends ...
-
(2003)Using Muskhelishvili's method, we present closed-form analytical solutions for an isolated elliptical inclusion in general shear far-field flows. The inclusion is either perfectly bonded to the matrix or, as in the case ...
-
(2006)Exact analytical solutions have been derived rigorously for the pore-fluid velocity, pore-fluid-flow focusing factor, stream function and excess pore-fluid pressure around and within a buried inclined elliptic inclusion ...
-
(2006)Analytical solutions are presented for solute transport in rivers including the effects of transient storage and first order decay. The solute transport model considers an advection-dispersion equation for transport in the ...
-
(2006)A stochastic model of the microstructure of rainfall is used to derive explicit expressions for the magnitude of the sampling fluctuations in rainfall properties estimated from raindrop size measurements in stationary ...
-
(2001)Analytical studies are carried out to investigate groundwater-head changes in a coastal aquifer system in response to tidal fluctuations. The system consists of an unconfined aquifer, a semi-confined aquifer and a ...
-
(2002)Small-scale analyses of volatiles in minerals and glasses provide information on how volatiles influence high-temperature geologic processes and low-temperature alteration processes. Four techniques for determining the ...
-
(2003)Isotopic analysis of heavy elements in individual stardust grains is important in testing and constraining theories of stellar nucleosynthesis. These analyses are challenging in that the grains are very small, the largest ...
-
(1997)In an effort to elucidate the processes of lunar mantle melting, and the magma evolution of mare basalts within Oceanus Procellarum on the western lunar near-side, we have analyzed seven fine-grained to vitrophyric Apollo ...
-
(2006)Tectonic escape is frequently considered to result from compression in a collisional belt, a free boundary opening the way to lateral extrusion of rigid blocks. However, in Anatolia the complex tectonic history provides ...
