    There are many complex, well structured problems, where a hierarchical structure within the data is present. This means, that one or several components of the structure are determined at a higher level by a sub-tree of other components. The concept of fuzzy signatures was introduced to help model these kinds of problems. The data set belonging to a problem has an arbitrary structure, but due to so... View full abstract»

    There are many processes which have periods when they operate abnormally. These periods are not regular ones, therefore their detection and control require hard activity because statements of regular processes will change suddenly, or their statement might not be determined exactly. They are operated by chaotic functions which can be transformed into catastrophe function by fuzzy control. View full abstract»
