    Using Control Charts for The Creation of a System of Intelligent Alarms in Power Facilities of Nuclear Power Plants,

    journal article

    During the creation of systems of intelligent alarms in power facilities of nuclear plants, a problem was encountered of how to detect quickly and effectively (in real time) beginning instability of a process described by about 140 characteristics and to warn the control centre that, without appropriate measures, an emergency event is highly probable. Therefore, it is proposed that the classic control charts should be used to monitor process stability. Because of many characteristics being auto-correlated and non-stationary, range and moving range control charts were found to best and will be implemented in a future software application.

    Nowadays is it a common practice to add vegetable protein in the production of meat products. Because of the possible substitution of high-quality raw meat with vegetable protein without the labelling the product package and because of the allergenic potential of many vegetable proteins, it is important to develop accurate methods for its detection. The objective of the study was to compare histochemical, immunochemical (ELISA, ALERT gliadin screening test) and immunohistochemical methods for the detection of wheat protein in meat samples and sausages. Histochemical methods were useful for the detection of flour in meat samples, but the immunohistochemical method was better for the detection of wheat protein. ALERT gliadin screening test detected gliadin from 10 mg kg(-1), while an immunohistochemical method detected wheat protein concentrations from 1 g kg(-1) and an ELISA method detected wheat protein concentrations from 4 g kg(-1). ALERT gliadin screening test showed results within 1 day, whilst an ELISA detection method took 2 days, and an immunohistochemical procedure took 5 days at the soonest, all including sample preparation. This study also focused on optimisation of an immunohistochemical method for samples of cooked sausage. In addition, three samples were sufficient for wheat protein detection at a concentration of 1 g kg(-1) (and greater) with a confidence level greater than 95%.

    Abstract: Measurement system errors can be classified into two categories: accuracy and precision. Accuracy describes the difference between the measurement and the part's actual value. We focus to precision which describes the variation you see when you measure the same part repeatedly (by same or by other operators) with the same device by Gage R&R Study. Gage repeatability and reproducibility studies determine how much of your observed process variation is due to measurement system variation.

    Fuzzy distances,
    Kybernetika, Vol.41, (2005), No.3, pp.375-389, ISSN 0023-5954
    journal article

    In the paper, three different ways of constructing distances between vaguely described objects are shown: a generalization of the classic distance between subsets of a metric space, distance between membership functions of fuzzy sets and a fuzzy metric introduced by generalizing a metric space to fuzzy-metric one. Fuzzy metric spaces defined by Zadeh's extension principle, particularly to Rn are dealt with in detail.
