Compositions for controlling anomalies in the film formed by wrinkle finish powder coating compositions are disclosed as are finished form powder coating compositions, methods and uses. The methods generally involve contacting the glass articles with a substantially fluoride-free aqueous acidic treating medium for a time at least sufficient to increase the rupture failure points of the glass articles. The addition of timing over Ethernet and power over Ethernet allows a radiation measurement system to operate with a single Ethernet cable, simplifying deployment of detectors using standardized technology with a multitude of configuration possibilities. The visual cameras make it possible to define the position of the details of the environment by a triangulation method and another triangulation is carried out in order to know the position of the sources after having moved the apparatus. A first adjusted diffraction signal is generated by adjusting the first measured diffraction signal using the first spectra-shift offset and the first noise weighting function.
