Profile: Snape Signals Research is an engineering consultancy specializing in the development of algorithms and electronics for processing signals and data. The consultancy covers single processing, pattern recognition, and data mining. Single processing approach is effective for ferritic steels, but can be difficult in stainless steel because the metal grain size is comparable with defect size. A common task in pattern recognition is completion of a mapping function given only fragments of the complete function. Data mining is the discovery of hidden relationships, similarities, and differences between records in the data set.
