Elasto-Thermodiffusive Response in a Two-Dimensional Transversely Isotropic Medium
The present article investigates the elasto-thermodiffusive interactions in a transversely isotropic elastic medium in the context of thermoelasticity with one relaxation time parameter and two relation time parameters. The resulting non-dimensional coupled equations are applied to a specific problem of a half-space in which the surface is free of tractions and is subjected to time-dependent th...
متن کاملLarge eddy simulation of two - dimensional isotropic turbulence
Large eddy simulation (LES) of forced, homogeneous, isotropic, two-dimensional (2D) turbulence in the energy transfer subrange is the subject of this paper. A difficulty specific to this LES and its subgrid scale (SGS) representation is in that the energy source resides in high wave number modes excluded in simulations. Therefore, the SGS scheme in this case should assume the function of the en...
متن کاملIsotropic inverse-problem approach for two-dimensional phase unwrapping.
We propose a new technique for two-dimensional phase unwrapping. The unwrapped phase is found as the solution of an inverse problem that consists in the minimization of an energy functional. The latter includes a weighted data fidelity term that favors sparsity in the error between the true and wrapped phase differences, as well as a regularizer based on higher-order total variation. One desira...
متن کاملTwo-Dimensional Correlation of Isotropic and Directional Diffusion Using NMR.
Diffusion nuclear magnetic resonance (NMR) is a powerful technique for studying porous media, but yields ambiguous results when the sample comprises multiple regions with different pore sizes, shapes, and orientations. Inspired by solid-state NMR techniques for correlating isotropic and anisotropic chemical shifts, we propose a diffusion NMR method to resolve said ambiguity. Numerical data inve...
متن کاملSampling theorems for two-dimensional isotropic random fields
The construction suggested by Lemma 1 enables transformation of a prof?lem of maximization of E, to a problem of maximiza-tion of E , ; hence randomness can be introduced. To summarize, given a quadratic function of the form E, or E,, it is possible to construct a neural network which will perform a random local search for the maximum. A rich class of optimization problems can be represented by...
