A method and system for decoding information that is output by an information source and transmitted in coded fashion via a transmission channel affected by interference, wherein the influence of statistical information, which is applied along side the transmitted information via the information source, on the decoding is modified as a function of the reliable of the decoding. The scores provided by the various scoring engines are adapted to provide a visual andor numerical feedback that provides information pertaining to correctness or incorrectness in one or more speech-features such as intonation, articulation, voicing, phoneme error and relative word duration. Also, the switchable polymer, processes for producing such polymers and compositions, and switchable adhesive articles comprising the adhesive compositions, such as light-switchable pressure sensitive adhesive dressings, and methods of using such articles. Paraffins without complete conversion result in products with less aromatics and relatively low density compared with the products directly from zeolite upgrading. A plant is used for manufacturing a hardened formed part.
