The second reason has to do with the homogeneity requirement of pure substances.
In contrast with Helmholtz's analysis, which presupposes the homogeneity of space, the Postulate of Freedom allows for the possibility of replacing Helmholtz's homogeneity requirement with the possibility of subjecting the metric field to arbitrary, infinitesimal change.
The RT treatment technique typically used opposed posterior to anterior and opposed lateral field arrangement for the whole pelvis [ 6] to fulfil the homogeneity requirement.
Abass, A., Gestel, D. V., Wichelen, K. V., Maes, B. & Burgelman, M. On the diffusion length and grain size homogeneity requirements for efficient thin-film polycrystalline silicon solar cells.
In this study, we demonstrate the development of optimized beamlet IMRT plans that satisfy rigorous dose homogeneity requirements for all target volumes (e.g., ±5%), while also sparing the parotids and other normal structures.
We consider the problem of adjudicating conflicting claims, and characterize the family of rules satisfying four standard invariance requirements, homogeneity, two composition properties, and consistency.
Care was taken in the modeling process to satisfy homogeneity and homoscedasticity requirements in the regression/calibration analyses.
Since homogeneous partitions that define equivalent reduced-state-space MDPs can have a large number of blocks, we relax the requirement of homogeneity.
Parameters such as internal clogging, homogeneity of spray, the requirement for gas or vacuum house lines, the number of parts that must be handled, and the time required to assemble the applicator, load it, and have it ready for use are also discussed.
The requirement for homogeneity is not relevant in CCF management where uneven size, growth rate and gradual revival of the understorey are benefits rather than shortcomings (Lähde et al., 2010).
In some cases the minimum number possible may be less than either of these if the requirement for homogeneity is relaxed and a mix of current and voltage variables allowed.
