Alas, since Reichenbach reckoned the affine structure of the gravitational-inertial field to be just as conventional as its metrical structure, he was not able to recognize this method as other than an equivalent, but by no means necessarily preferable, account of the empirical determination of the metric through the use of rods and clocks (Coffa, 1979; Ryckman 2005,chs. 2 & 4).
Some brands have recognized this and tried methods that ultimately failed.
Two categories of factory cost are recognized under this method: prime costs and factory overhead costs.
Although subtle changes in processes are not the goal to be recognized by this method, general changing trends in processes will be understood using the proposed fuzzy recognition model, which is good to realize suboptimal process control.
Patterns were well recognized using this method but prior knowledge of the number of clusters is a prerequisite.
Though these results are promising, there are several caveats that must be recognized with this method.
This method is not universally applicable and many compounds particularly those from natural origin e.g. antibiotics etc. are not recognized by this method as drug-like compounds [ 10].
Nonetheless, it should be recognized that this method is much more affordable than analytical chemistry methods and, most important, it has successfully been used to measure BPA in samples in a comparable dose range and in a similar percentage of samples as the methods that are considered more accurate (Vandenberg et al. 2007).
In male Or67d-GAL4 samples that did not express the synaptic label (normally have ∼1500 puncta), but were processed identically using primary and secondary antibodies, the number of puncta recognized by this method was <30, suggesting that the 'false positive' rate was low.
However, disappointingly, in an extensive human proteomic analysis by Helgeland et al., no plasma protein could be conclusively demonstrated to be regulated via RIPC, although they recognized that this method has limited sensitivity in the range of low to medium abundance proteins [ 71].
