Pressure in the Average-Atom Model
The (well-known) quantum mechanical expression for the stress tensor is derived and applied to obtain a formula for the pressure in the average-atom model. This average-atom pressure formula reduces to the (well-known) expression for the pressure in a classical free-electron gas when the average-atom continuum wave functions are replaced by free-electron wave functions. 1 Derivation We start wi...
متن کاملA Moving Average Bidirectional Texture Function Model
The Bidirectional Texture Function (BTF) is the recent most advanced representation of visual properties of surface materials. It specifies their appearance due to varying spatial, illumination, and viewing conditions. Corresponding enormous BTF measurements require a mathematical representation allowing extreme compression but simultaneously preserving its high visual fidelity. We present a no...
متن کاملOptical Properties of Plasmas Based on an Average-Atom Model
Optical properties of plasmas, including dielectric constants, indices of refraction, and absorption coefficients, are determined from an average-atom point of view. Linear response of an average atom to an harmonic electric field leads to an averageatom version of the Kubo-Greenwood formula, which is used to calculate the frequencydependent electric conductivity of the plasma. The frequency-de...
متن کاملHemispheric average Cl atom concentration
Methane is a significant atmospheric trace gas in the context of greenhouse warming and climate change. The dominant sink of atmospheric methane is the hydroxyl radical (OH). Recently, a mechanism for production of chlorine radicals (Cl) in the marine boundary layer (MBL) via bromine autocatalysis has been proposed. The importance 5 of this mechanism in producing a methane sink is not clear at ...
متن کاملA Compound Moving Average Bidirectional Texture Function Model
This paper describes a simple novel compound random field model capable of realistic modelling the most advanced recent representation of visual properties of surface materials the bidirectional texture function. The presented compound random field model combines a non-parametric control random field with local multispectral models for single regions and thus allows to avoid demanding iterative...
