Abstract: A method for automatically identifying and correcting errors in electronily stored character strings input from handwritten character strings is disclosed. The input character strings are compared to a predetermined list of correct character strings by dividing the input character string and each of the correct character strings into at least one character string fragment. Each character string fragment or set of character string fragments is formed by applying at least one different fragmentation submethod to the character string. The corresponding fragments from the input character string and the correct character strings are then compared in turn. The correct character string producing a unique lowest comparison value is determined to be the correct character string intended by the input character string. Accordingly, the determined correct character string is output in place of the input character string.

Abstract: A control system emulates an X-ray spectrum generation and analyzing system on a computer by emulating the experimental apparatus, emulating the experimental geometry between elements of the experimental apparatus and emulating a material sample within the experimental apparatus including the emulated material sample's physical properties. The control system allows an operator generate theoretical spectra of material samples based on the emulated experimental apparatus and the physical characteristics of the emulated material sample. The control system also allows the operator to compare the generated theoretical spectrum to a real spectrum acquired from the experimental system and sample which have been emulated. Thus, the operator can easily determine the sufficiency of the emulation of the experimental set-up. The control system further allows the operator to analyze the generated theoretical spectra.
