J-Parameter Based Upon the Ubiquitous Geometrical Factor [eta]
The idea we explored is based on the popular expression giving J as a function of the ubiquitous geometrical factor [eta] and proposed in the case of elastoplastic mechanical behavior (13-16), (44-47).
Using the membrane permeation model, the effective diffusion coefficient is measured by measuring polymer intrinsic diffusion coefficient and solubility of the gas component in the polymer matrix for all the gases involved (14, 15): it is also necessary to assume a geometrical factor that accounts for the influence of foam morphology on the effective diffusion coefficient.
Because the former angle is larger than the latter one, geometrical optics suggests that the total power detected depends only on the blackbody temperature and a geometrical factor related to the pinhole aperture, detector optics, and relative separation, because the detector pupil is overfilled.
In literature, is appreciated the contribution of different sources to these errors, concluding the fact that errors due to the geometrical factors represent (9095)% of robots and manipulators pose errors.
A greatly talented designer, all of Jens Juul Eilersen's sofas are created according to classic measures and proportions, such as the "golden cut and square" where the geometrical factors ensure balance and harmony in both function and expression.
Their geometrical factors, along with operating stresses and corrosive operating environments require a deep understanding of the material requirements for long-lived suction roll shells.
The control factors are the geometrical factors of the drawing tools (a) and the technological factors of the drawing process (b) that are shown in Fig.
The determination of the geometrical factors is often quite challenging as well.
The calculation takes account of the following: purely geometrical factors such as the variation in irradiated area with incident beam angle and the effect of absorption; and the effect of defocussing, which is the variation in scattering angle at different parts of the irradiated specimen surface when the specimen is tilted out of the symmetrical orientation.
