STOCHASTIC GALERKIN DISCRETIZATION OF THE LOG-NORMAL ISOTROPIC DIFFUSION PROBLEM

Mathematical Models and Methods in Applied Sciences, 2010
The stochastic Galerkin method is developed for the isotropic diffusion equation with an unbounded random diffusion coefficient. The logarithm of the diffusion coefficient is assumed to be an infinite series of Gaussian random variables. Well-posed weak formulations of the model problem are derived on standard Bochner–Lebesgue spaces.

Euler-like vector fields, normal forms, and isotropic embeddings

Indagationes Mathematicae, 2021
Germs of tubular neighborhood embeddings for submanifolds N of manifolds M are in one-one correspondence with germs of Euler-like vector fields near N. In many contexts, this reduces the proof of `normal forms results' for geometric structures to the construction of an Euler-like vector field compatible with the given structure.

Interaction of isotropic turbulence with a normal shock wave

Applied Scientific Research, 1993
The evolution of incompressible and compressible isotropic 2-d turbulent fields interacting with a normal shock wave up to Mach numbers of 2.4 was investigated by means of direct numerical simulation using an ENO scheme. A comparison of statistics with linear analysis results is presented.

The normal spectral emissivity of isotropic and anisotropic materials

Carbon, 1965
Abstract The correlation of structural anisotropy with the normal spectral emissivity of pyrolytic graphite is discussed relative to polycrystalline graphite and to isotropic single crystal nickel. Results reported include data in the near infrared (1.5–13μ) at temperatures between 800 and 1200°C in a hydrogen atmosphere. Photomicrographs (up to 1000×

Coarse‐to‐Fine Normal Filtering for Feature‐Preserving Mesh Denoising Based on Isotropic Subneighborhoods

Computer Graphics Forum, 2013
AbstractState‐of‐theart normal filters usually denoise each face normal using its entire anisotropic neighborhood. However, enforcing these filters indiscriminately on the anisotropic neighborhood will lead to feature blurring, especially in challenging regions with shallow features.
