    Notes: Abstract The studies presented in this paper deal with the global recognition of a restricted variety of handwritten words comprising the vocabulary used to write French bank checks. Several tools have been developed within the constraints of this application, tools that relate to the general problem of off-line cursive handwriting recognition. The first difficulty when one wants to read a text is the location of words. This is done by using a top-down analysis that first locates lines of text before segmenting them into individual words. A structural model of cursive handwriting, built on the median axis of the word, is proposed. This constitutes an alternative to the use of the conventional, letter-by-letter analytical model and could be used for other problems involving cursive word recognition. According to this structural model of cursive handwriting, an edit distance is computed between the extracted structural description and the reference descriptions that are interpreted as grapheme strings. This provides an ordered list of candidates for each individual word. Feature extraction in the binary image of the word is performed using a specific line-following algorithm. Since it is possible to express the syntax of the sentences by a finite grammar, this information is used to discard the inconsistent sentences from the possible ones. These various algorithms have been tested on personal data, as well as on real check images.

    Structural analysis of Arabic handwriting: segmentation and recognition (1995)
    Springer
    Machine vision and applications 8 (1995), S. 232-240

    ISSN: 1432-1769

    Notes: Abstract In this paper, a structural method of recognising Arabic handwritten characters is proposed. The major problem in cursive text recognition is the segmentation into characters or into representative strokes. When we segment the cursive portions of words, we take into account the contextual properties of the Arabic grammar and the junction segments connecting the characters to each other along the writing line. The problem of overlapping characters is resolved with a contour-following algorithm associated with the labelling of the detected contours. In the recognition phase, the characters are gathered into ten families of candidate characters with similar shapes. Then a heterarchical analysis follows that checks the pattern via goal-directed feedback control.

    Identifiability and distinguishability of fundamental parameters in catalytic methanation (1986)
    Hoboken, NJ : Wiley-Blackwell

    Notes: Methods are presented to determine structural identifiability and distinguishability of parametric models. Results are applied to transient isotope tracing of methanation over a nickel catalyst. More meaningful information is obtained in this way about fundamental parameters than is possible by empirical curve-fitting.

    Structural identifiability of “first-pass” models (1987)
    Springer
    Journal of pharmacokinetics and pharmacodynamics 15 (1987), S. 179-189

    ISSN: 1573-8744
    Keywords: First-pass effect ; structural identifiability ; compartmental models

    Topics: Chemistry and Pharmacology
    Notes: Abstract This paper considers the structural identifiability of two compartmental models classically used to describe the pharmacokinetics of drugs orally administered and transformed into a metabolite with a firstpass effect at the hepatic level. The simplest model proves not to be globally identifiable even when plasma and urinary measurements of the drug and metabolite concentrations are made. It admits two sets of admissible solutions, so that a prioriknowledge must be introduced to distinguish them. The more complex model appears globally identifiable when blood and urine measurements are made.
