Using a new density-functional equation proposed by us recently, frequency-dependent 2 L-pole (L = 1, 2, 3, 4) polarizabilities of He, Ne, Ar, Kr and Xe in their ground states have been calculated by numerically solving for each frequency only two, instead of 2N (N = number of ...
A radio-frequency (RF) inductive ion source at 27.12 MHz is investigated. With a global model of the argon discharge, plasma density, electron temperature and ion current density of the ion source is calculated in relation to absorbed RF power and gas pressure as a discharge chamber size ...
In the Contour Options dialog, the following options are available which control the way that Dips computes the pole density concentration values for the data:Fisher Distribution Schmidt Distribution Count Circle SizeThe Schmidt distribution method provides very quick computation time and, for large ...

Six parameters were used through plate modeling: length, width, thickness, poisonsup/sups ratio, modulus of elasticity and density. This study intends to estimate the natural frequency of seven different metals as follow: high strength low alloy steel, gray iron, aluminum by alloy 1100-H14 and...
We have calculated molecular geometries, HOMO-LUMO gaps, Fermi levels and vibrational frequencies for the σ-linear, σ-bent and π-coordinated [Au20-C60-Au20]n− (n = 0–3) complexes using the density functional B3LYP method and LANL2DZ basis sets. Our calculations showed that the σ-...
