Abstract: The present teachings relate to a method comprising a plurality of sensors, and one or more functionally connected processing units, the method comprising: providing, at any of the one or more processing units, time-series residual data of a sensor object; the sensor object being a group of at least some of the sensors from the plurality of sensors, and wherein the residual data comprises, for each of the sensors of the sensor object, a residue signal which is a difference between the sensor's measured output and the sensor's expected output, monitoring, via any of the one or more processing units, a level signal; wherein the level signal is indicative of a collective time-based variation of the time-series residual data, monitoring, via any of the one or more processing units, an association signal; wherein the association signal is indicative of the variation and/or association structure of the time-series residual data, generating, via any of the one or more processing units, an anomaly event signal when at a given time a value of the level signal and/or a value of the association signal changes from an expected value of the respective signal at or around that time. The present teachings also relate to a monitoring and/or control system for a plant comprising a plurality of sensors, wherein the system comprises one or more processing units configured to perform the method steps of any of the steps herein disclosed, and a computer software product.

Abstract: Plasticizer migration-resistant, UV-curable hotmelt adhesive for graphics films and labels made of plasticized PVC
Described here is a UV-curable hotmelt adhesive largely resistant to plasticizer migration and comprising a UV-crosslinkable poly(meth)acrylate formed from methyl acrylate, C4-18 alkyl (meth)acrylate, monomer with acid groups, copolymerized photoinitiator and optionally further monomers. The hotmelt adhesive further comprises an aliphatic polyester polymer. The use of the hotmelt adhesive on graphics films and self-adhesive labels made of plasticized PVC is also described.
